Description

Insulated container that uses vacuum insulation and can be assembled and disassembled

The present invention relates to a heat insulating container that uses a vacuum heat insulating material and can be assembled and disassembled.

The vacuum heat insulating material has a core material and an outer packaging material, and the inside of the bag constituted by the outer packaging material is maintained in a vacuum state in which the core material is disposed and the pressure is lower than the atmospheric pressure. . Since heat convection inside the bag is suppressed, the vacuum heat insulating material can exhibit good heat insulating performance. Since the heat insulating performance per unit thickness is higher than that of a general foam heat insulating material, the vacuum heat insulating material can reduce the thickness of the heat insulating material while ensuring desired heat insulating properties. Therefore, by using the vacuum heat insulating material for the heat insulating container, it is possible to reduce the weight and space of the heat insulating container.

A heat insulating container using a vacuum heat insulating material and capable of being assembled and disassembled is disclosed in Patent Documents 1 to 3, for example.

If the vacuum insulation material breaks and the internal vacuum state is broken, the heat insulation performance is drastically lowered. Therefore, the heat insulation container in which the vacuum heat insulating material is used is generally configured such that the protective material is disposed outside the panel constituting the heat insulating container, and the vacuum heat insulating material is disposed inside thereof. Even when a force is applied from the outside of the heat insulating container, the vacuum heat insulating material is hardly damaged because it is protected by the protective material. As the protective material, a material mainly composed of an organic polymer material having low thermal conductivity such as cardboard, plastic cardboard, or plate-like wood is generally used. When a metal part mainly composed of a metal material is used as a component of a heat insulating container, the heat conductivity of the metal material is high, so heat is transmitted through the metal part, and the heat insulating performance of the heat insulating container is reduced. May decrease.

(I) 1st invention The 1st invention of this indication is explained.

(1) The entire heat insulating container of the first invention of the present disclosure (a) The heat insulating container of the first invention of the present disclosure The first invention of the present disclosure is a heat insulating container that uses a vacuum heat insulating material and can be assembled and disassembled. is there. The heat insulation container is capable of forming a heat insulation space surrounded by the side panel, the top panel, and the bottom panel, and is in a disassembled state in which the heat insulation space is not formed from the assembled state in which the heat insulation space is formed. It is possible to change to the assembly state. The side panel of the heat insulation container includes an outer panel and an inner panel arranged on the panel surface of the outer panel on the heat insulation space side. The inner panel includes a heat insulating portion including a vacuum heat insulating material. The outer panel includes a metal support portion made of metal that continuously extends from an end of the side panel on the top panel side to an end of the side panel on the bottom panel side in the assembled state. In the assembled state, the metal support portion does not contact the heat insulating space formed by the panel surface on the heat insulating space side of the side panel, the panel surface on the heat insulating space side of the top panel, and the panel surface on the heat insulating space side of the bottom panel.

(B) Demand for heat-insulating container according to the first invention of the present disclosure The heat-insulating container is used, for example, in the physical distribution field for storage and transportation of articles that need to be kept cold or warm. Such a heat insulating container is generally a heat insulating space in which the inside of the container capable of storing articles is surrounded by a heat insulating panel so that the temperature change inside the container is suppressed as much as possible. It is configured. In order to ensure heat insulation performance, the insulation panel needs to have a certain thickness. Therefore, the heat insulating container has a problem that the volume inside the container is smaller than that of a normal container. Therefore, by constructing the insulated container so that it can be assembled and disassembled, the insulated container is assembled and used for luggage that requires temperature control, and the normal container is used for luggage that does not require temperature management. Insulated containers can be used and stored after being disassembled.

However, as the heat insulation container becomes larger, the heat insulation panel required for the heat insulation container also becomes larger, but the large heat insulation panel is heavy and difficult to handle. Therefore, in general, an insulating container that can be assembled and disassembled has dimensions of cm order. However, as for the flat pallet widely used in the physical distribution field, for example, the T11 type standardized by JIS as a flat pallet for consistent transport in Japan is 1100 mm long × 1100 mm wide × 144 mm high. Insulated containers with dimensions of the order of cm may not be able to store the entire luggage to be transported and / or stored on a flat pallet.

Furthermore, in transportation and storage using a cargo handling platform such as a pallet, at least two cargo handling platforms are used to effectively utilize the limited space such as the cargo platform, containers, and warehouses of transport machines such as trucks, railways, ships, and aircraft. It is required that it can be stacked on the stage. However, even if each dimension of the conventional heat insulation container whose dimensions are on the order of cm is simply increased, it may not be able to withstand the load applied to the heat insulation container and the heat insulation panel may be damaged. In the foam insulation, even if a part of the foam insulation is damaged, the decrease in heat insulation performance is limited to the damaged part, but in the vacuum insulation, if a small part of the vacuum insulation is damaged As a result, the heat insulation performance of the whole vacuum heat insulating material is lowered. Therefore, in a heat insulating container using a vacuum heat insulating material, it is required to take measures to prevent the vacuum heat insulating material from being damaged as much as possible. Moreover, in order to improve the load resistance of a container, use of a metal material can be considered. However, since the metal material has high thermal conductivity, when using a metal material for the heat insulating container, it is required to take measures to prevent deterioration of the heat insulating performance as much as possible.

(C) Main structure of the heat insulating container The heat insulating container of the first invention of the present disclosure can form a heat insulating space surrounded by the side panel, the top panel, and the bottom panel, and the heat insulating space is It is possible to change from the assembled state to the disassembled state in which the heat insulation space is not formed, and to change from the disassembled state to the assembled state. Therefore, the heat insulation container of the first invention of the present disclosure can be stored and transported in a disassembled state reduced by disassembling and stacking when not in use.

The side panel includes an outer panel and an inner panel disposed on the panel surface on the heat insulating space side of the outer panel, and the inner panel includes a heat insulating portion including a vacuum heat insulating material. Since vacuum insulation has good insulation performance even if it is small in thickness, the use of vacuum insulation can reduce the weight of the side panel, increase the storage capacity of the assembled insulation container, The heat-insulated container in a decomposed state can be made compact.

The outer panel of the side panel includes a metal support portion made of metal that continuously extends from the end of the side panel on the top panel side to the end of the side panel on the bottom panel side. Since the metal support part supports the load from its own weight or the top surface side, the heat insulation container of the first invention of the present disclosure has a good load resistance, and when the heat insulation container is enlarged and attempted to be stacked in two stages. Even so, the risk of breakage of the vacuum heat insulating material can be reduced.

The metal support portion of the outer panel of the side panel is formed by the panel surface of the side panel on the heat insulation space side, the panel surface of the top panel on the heat insulation space side, and the panel surface of the bottom panel on the heat insulation space side. Do not touch the insulation space. Therefore, it can suppress that heat is transmitted through a metal support part and the heat insulation performance of a heat insulation container falls.

As described above, the heat insulating container of the first invention of the present disclosure is a heat insulating container that uses a vacuum heat insulating material and can be assembled and disassembled, and can obtain good load resistance and heat insulating performance.

(D) Ancillary structure of the heat insulation container In the heat insulation container, the outer side panel of the side panel has a part not provided with the metal support part, and the part is provided with a protective material made of organic polymer. The sum of the area occupied by the metal support portion on the panel surface on the heat insulation space side of the outer panel and the area occupied by the protective material on the panel surface on the heat insulation space side of the outer panel may be 40% or less may be sufficient as the ratio of the area which the said metal support part occupies on the panel surface by the side of the said heat insulation space of the said outer side panel. It is possible to improve the heat insulation performance and reduce the weight of the heat insulation container. This ratio can be 20% or less or 10% or less. On the other hand, this ratio may be 1% or more.

In the heat insulating container, the metal support portion of the outer panel of the side panel may be disposed at a corner of the heat insulating container, and the protective material of the outer panel of the side panel is a surface portion of the heat insulating container. May be arranged. The load resistance of the heat insulating container can be improved efficiently.

The heat insulation container may include a pallet, and the pallet may be disposed on a panel surface of the bottom panel of the heat insulation container opposite to the heat insulation space. Since the heat insulating container with a pallet can be easily moved by a forklift or a hand lift, the risk of accidentally damaging the vacuum heat insulating material used in the heat insulating container during the moving operation is reduced. The same applies to the second, third, and fourth inventions described later.

The bottom panel of the heat insulating container may be joined to the pallet. Each panel constituting the heat insulation container can be assembled with reference to the position of the bottom panel fixed integrally with the pallet, so it is easy to obtain good heat insulation performance by arranging each panel at an appropriate position Become. The same applies to the second, third, and fourth inventions described later.

The bottom panel of the heat insulating container may be separable from the pallet. Since a general-purpose pallet can be used, the usability of the insulated container according to the first invention of the present disclosure is improved. Further, when loading / unloading a load, for example, a corner portion of the load may accidentally collide with the bottom panel. If the bottom panel has a vacuum heat insulating material, the vacuum heat insulating material may be damaged by a collision, but only the bottom panel needs to be replaced, so that the repair becomes easy. The same applies to the second, third, and fourth inventions described later.

The side panel of the heat insulating container may include a protruding portion toward the bottom panel in the assembled state at an end on the bottom panel. Since the heat insulation container can be assembled with reference to the position of the protruding portion of the side panel, it is easy to obtain good heat insulation performance by arranging each panel at an appropriate position. An example of the protruding portion is a side guide portion described later. The same applies to the second, third, and fourth inventions described later.

In the heat insulating container, the outer peripheral shape of the side panel of the heat insulating container is such that, when the heat insulating container in the assembled state is viewed from the top surface side, the length of at least one pair of opposing two sides is 0.5 m or more. It may be a quadrilateral, or may be a quadrilateral with a length of at least one pair of two opposing sides being 1 m or more. With such an outer peripheral shape, the entire cargo to be transported and / or stored on a flat pallet can be stored. The heat insulating container has an outer peripheral shape of a side panel of the heat insulating container, and when the heat insulating container in the assembled state is viewed from the top surface side, the length of at least one pair of opposite sides is 1.4 m. The following quadrilateral may be used. When storing and transporting the insulated container, the risk of damage to the outer peripheral panel due to a collision can be reduced. The same applies to the second, third, and fourth inventions described later.

The outer peripheral shape and dimensions of the heat insulating container according to the first invention of the present disclosure are not particularly limited. In the heat insulation container of the first invention of the present disclosure, each dimension may be in the order of cm, or one or more of each dimension may be 1 m or more. As a specific example of the outer peripheral shape of the side panel of the heat insulating container, when the heat insulating container in the assembled state is viewed from the top surface side, the vertical width and the horizontal width are 1000 mm and 1200 mm, respectively. A quadrilateral of 1119 mm to 1319 mm and a horizontal width of 916 mm to 1116 mm, a quadrilateral having a vertical width of 1100 mm to 1300 mm and a horizontal width of 900 mm to 1100 mm, a vertical width of 1100 mm to 1300 mm and a horizontal width of 700 mm or more In addition, a quadrilateral having a length of 900 mm or less and a quadrilateral having a vertical width and a horizontal width of 1065 mm or more and 1265 mm or less can be given. By making the shape of the side panel suitable for the shape of the standard pallet in each country, the efficiency of transportation and storage can be improved. Further, as the outer peripheral shape of the side panel of the heat insulating container, for example, when the assembled heat insulating container is viewed from the top surface side, a quadrilateral having a vertical width of 795 mm or more and 995 mm or less and a horizontal width of 644 mm or more and 844 mm or less. It is good. By making the dimensions suitable for the shape of a standard carriage, transportation and storage can be made more efficient. The same applies to the second, third, and fourth inventions described later.

In the heat insulating container, the heat insulating portion of the inner panel of the side panel may include a foam heat insulating material on the heat insulating space side of the vacuum heat insulating material, and the vacuum heat insulating material is inside the heat insulating portion and the outer panel. It may be arranged side by side. By protecting the outside of the vacuum heat insulating material with the outer panel and protecting the inside of the vacuum heat insulating material with the foam heat insulating material, the vacuum heat insulating material is hardly damaged. By reducing or eliminating the foam heat insulating material disposed outside the vacuum heat insulating material, the capacity of the heat insulating container can be increased.

In the heat insulating container, the heat insulating portion of the inner panel of the side panel may include a foam heat insulating material between an end surface of the vacuum heat insulating material and an end surface of the inner panel. By filling the foam heat insulating material without providing a gap between the end surface of the vacuum heat insulating material and the end surface of the inner panel, it is possible to suppress a decrease in the heat insulating performance of the heat insulating container.

The heat insulating container may be arranged such that the outer panel of the side panel and the inner panel of the side panel are separable. If the vacuum insulation material on the inner panel breaks, only the inner panel needs to be replaced, which facilitates repair. Moreover, the said heat insulation container may be comprised so that the surface of the said vacuum heat insulating material can be visually observed when the said outer side panel and the said inner side panel are isolate | separated. Since abnormal deformation may occur on the surface of the damaged vacuum heat insulating material, it is possible to examine whether the vacuum heat insulating material is damaged by visually observing the vacuum heat insulating material without breaking the inner panel. In addition, when the heat shield sheet mentioned later has covered the vacuum heat insulating material, the surface of a vacuum heat insulating material can be visually observed by using a transparent heat shield sheet. Moreover, the said heat insulation container may be arrange | positioned so that the said vacuum heat insulating material can be isolate | separated from the said inner side panel. If the vacuum insulation on the inner panel breaks, the broken vacuum insulation can be easily replaced.

In the heat insulating container, the side panel may include a plurality of partial panels, and each of the plurality of partial panels is in an assembled state, and a panel surface on one end side of the inner panel is an inner panel of another partial panel. You may arrange | position so that an end surface may be contacted, and you may arrange | position so that the end surface of the other end side of an inner panel may contact the panel surface of the inner panel of another partial panel. The heat insulation performance of the heat insulation container is stabilized because of the internal panel arrangement structure that can withstand omnidirectional shocks from the side.

In the heat insulating container, the side panel may include a first partial panel and a second partial panel disposed on an end side of the first partial panel, and a panel surface of an inner panel of the first partial panel; The end surface of the inner panel of the second partial panel may be disposed via an elastic body. The side panel may include a first partial panel and a second partial panel disposed on an end side of the first partial panel. The panel surface of the inner panel of the first partial panel and the second partial panel The end surface of the inner panel may have an arc surface that is arc-shaped when viewed in a cross section perpendicular to the panel surface, and the first partial panel and the second partial panel are in an assembled state. The arc surfaces may be in contact with each other. The side panel may include a first partial panel and a second partial panel disposed on an end side of the first partial panel, and end surfaces of inner panels of the first partial panel and the second partial panel are The first partial panel and the second partial panel may be in an assembled state when viewed in a cross section perpendicular to the panel surface. The inclined surfaces may be arranged so as to contact each other. In the heat insulating container, the side panel may include a first partial panel and a second partial panel disposed on an end side of the first partial panel, and an end of the inner panel of the first partial panel; The end portion of the inner panel of the second partial panel may be arranged to form a fitting structure. These arrangement structures improve the heat insulation performance of the heat insulating container because the inner panels are joined to each other.

In the heat insulating container, the side panel is disposed on a first partial panel, a second partial panel disposed on one end side of the first partial panel, and on the other end side of the first partial panel. A third partial panel may be provided, and the first partial panel can be opened and closed by rotating with respect to the plate portion around the linear rotation center and the plate portion constituting the wall surface in the assembled state. A door portion may be provided, and the position of the end surface on the top surface side of the outer panel of the first partial panel may be the position of the end surface on the top surface side of the outer panel of the second partial panel and the position of the first surface. It may be lower than the position of the end surface on the top surface side of the outer panel of the three-part panel. The first partial panel can be easily opened and closed. For example, a front panel described later as the first partial panel, a right panel described later as the second partial panel, and a left panel described later as the third partial panel can be used. However, the present invention is not limited to this, and when there is an openable / closable panel other than the front panel, the panel may be configured as described above as the first partial panel.

In the heat insulating container, the side panel may include a plate portion constituting a wall surface, and a door portion that can be opened and closed by rotating with respect to the plate portion around a linear rotation center. When the orthogonal cross section is viewed, the boundary surface between the plate portion and the door portion in the closed state of the door portion may not be on the same plane. Heat transfer through the boundary between the plate portion and the door portion is suppressed, and the heat insulating performance of the heat insulating container is improved. Further, the position where the outer panel on the plate part side and the outer panel on the door part side are in contact with the position where the inner panel on the plate part side and the inner panel on the door part side are arranged is shifted, The boundary surfaces may not be on the same plane, and may be bent, for example. Since the inner panel on the plate part side or the inner panel on the door part side covers the position where the outer panel on the plate part side and the outer panel on the door part side contact, more heat transfer through the boundary between the plate part and the door part Can be suppressed. The end face of the inner panel on the plate part side and / or the door part side in the opened state of the door part may have a display part. Since the display unit works as a warning, it can reduce the risk of damage to the vacuum insulation due to the impact on the edge of the inner panel on the plate part side or the inner panel on the door part side that is not protected by the outer panel. it can.

The side panel or the top panel is an openable / closable door part, a latch mechanism for holding the door part in a closed state, and connected to the latch mechanism to release the holding state of the door part by the latch mechanism. There may be provided an operation member that is operated in a movable manner, and a deformable handle portion that is disposed on the door portion so as to cover at least a part of the operation member. When assembling or disassembling the heat insulation container, it is possible to reduce a risk that the operation member accidentally hits the inner panel and the vacuum heat insulating material is damaged.

In the heat insulating container, the top panel is separable from the side panel and can be folded. When assembling or disassembling the heat insulating container, it is easy to raise and lower the top panel, and the risk of the vacuum heat insulating material being damaged due to the top panel accidentally hitting the inner panel can be reduced.

In the heat insulating container, a bottom protective material made of organic polymer may be disposed on the heat insulating space side of the bottom panel. Since a protective material using an organic polymer material having relatively low heat conductivity is used, the heat insulation performance is unlikely to deteriorate. If the bottom panel has a vacuum heat insulating material, the risk of breakage of the vacuum heat insulating material can be reduced.

In the heat insulating container, the side panel may be separable into a plurality of panels in the disassembled state of the heat insulating container, and the end surface of the side panel is an indication for identifying the order in which the plurality of panels are stacked. You may have a part. The efficiency of the work of assembling or disassembling the heat insulating container can be improved.

The side panel 1110 includes a right panel 1120, a left panel 1130, a back panel 1140, and a front panel 1150. Each of side panel 1110, top panel 1170, and bottom panel 1190 is a heat insulating panel including a heat insulating portion including a vacuum heat insulating material, as will be described later. In this example, the top panel 1170 and the bottom panel 1190 include a heat insulating portion including a vacuum heat insulating material, but this is not a limitation. For the heat insulating portions of the top panel 1170 and the bottom panel 1190, for example, a heat insulating material that is not a vacuum heat insulating material such as a foam heat insulating material may be used. Further, the right panel 1120 and the left panel 1130 include a metal support portion 1310 and a frame portion 1320. The metal support portion 1310 as a vertical frame and the frame portion 1320 as a horizontal frame constitute the entire frame of the outer panel of each panel. Although not shown, the back panel 1140 and the front panel 1150 are similarly provided with a metal support portion 1310 and a frame portion 1320. In this example, the area other than the frame of the outer panel of each panel is provided with a protective material mainly composed of an organic polymer material described later, but this is not a limitation, and the entire outer panel The metal support part may be comprised and the other metal support part may be arrange | positioned in areas other than the frame of an outer side panel. Moreover, the ratio which a metal support part accounts in an outer side panel may be more or less than this example. The shape of the metal support is also not particularly limited, and it is sufficient that a portion that continuously extends from one end of the panel to the other end exists in the metal support.

In addition, in this specification, in order to make an understanding easy, the direction and position in the heat insulation container 1100 may be described as follows.

The direction from the bottom panel 1190 toward the top panel 1170 perpendicular to the panel surface of the bottom panel 1190 is the + Z direction or the upward direction, and the opposite direction to the + Z direction is the −Z direction or the downward direction. The + Z direction and / or the −Z direction may be simply referred to as the Z direction. Of the horizontal plane, which is a plane perpendicular to the + Z direction, the direction perpendicular to the panel surface of the back panel 1140 from the back panel 1140 to the front panel 1150 is defined as the + X direction, and the opposite direction to the + X direction is defined as the −X direction. The + X direction and / or the −X direction may be simply referred to as the X direction. The direction from the left panel 1130 to the right panel 1120 perpendicular to the panel surface of the right panel 1120 orthogonal to the + X direction is defined as the + Y direction, and the opposite direction to the + Y direction is defined as the −Y direction. The + Y direction and / or the −Y direction may be simply referred to as the Y direction.

The main surface of each panel is the panel surface, and the other surfaces are the end surfaces. The panel surface side of each panel on the heat insulation space side is the inside of the panel, and the panel surface side opposite to the panel surface side on the heat insulation space side is the outside of the panel.

The front panel 1150 and the top panel 1170 have a structure that can be partially opened and closed, and FIG. 1 shows a partially opened state. The insulated container 1100 in FIG. 1 is in an assembled state of a quadrangular prism structure by closing the front panel 1150 and the top panel 1170, and is surrounded by the side panel 1110, the top panel 1170, and the bottom panel 1190. It is possible to form an insulated space inside the container.

As shown in FIG. 2, the heat insulating container 1100 in the assembled state in which the heat insulating space 1300 is formed includes a right panel 1120, a left panel 1130, a rear panel 1140, a front panel 1150, and a top panel 1170 as a bottom panel 1190 and a pallet. By separating from 1500, it is possible to have a disassembled state in which the heat insulating space 1300 is not formed. Obviously, contrary to that shown in FIG. 2, it is possible to change to the heat insulating container 1100 in the assembled state by connecting the panels of the heat insulating container 1100 in the disassembled state.

As shown in FIG. 2, a front panel 1150, a left panel 1130, a back panel 1140, and a right panel 1120, which are side panels 1110, are an

outer panel

1150B, 1130B, 1140B, 1120B, and an

inner panel

1150A, 1130A, 1140A, 1120A, respectively. Is provided. The top panel 1170 includes an outer panel 1170B and an inner panel 1170A. The bottom panel 1190 includes an inner panel 1190A. Although not shown, each of the inner panels includes a heat insulating portion including a vacuum heat insulating material. Since the inner panel 1190A is protected by the pallet 1500, the bottom panel does not include the outer panel in this example, but this is not a limitation, and the bottom panel may include the outer panel. . Accordingly, it is possible to suppress the bottom panel from being pressed against the unevenness on the surface of the pallet 1500 due to the load of the load and damaging the vacuum heat insulating material of the inner panel 1190A of the bottom panel. Further, in this example, the top panel 1170 includes the outer panel 1170B, but this is not a limitation, and the top panel may not include the outer panel 1170B. When the top panel 1170 includes the outer panel 1170B, when the heat insulating containers are stacked in two stages, the vacuum heat insulating material included in the inner panel 1170A of the top panel 1170 of the lower cool box by the bottom surface of the upper cool box. Can be prevented from being damaged.

As shown in FIGS. 1 and 2, the right panel 1120, the left panel 1130, and the front panel 1150 are respectively located on the left and right ends of the panel from the end on the top panel side, which is the upper side of the panel, below the panel. The metal support part 1310 made from a metal is provided which extends continuously to the end part on the bottom panel side which is the side. Although not shown, the same applies to the rear panel 1140. The metal support portion 1310 made of metal serves as a column or wall that supports the weight of the panel or the load from the top surface side.

As shown in FIGS. 1 and 2, the heat insulation space 1300 of the heat insulation container 1100 is in an assembled state, the panel surface inside the side panel 1110, the panel surface inside the top panel 1170, and the panel surface inside the bottom panel 1190. It is formed by. The panel surfaces on the heat insulation space 1300 side of the side panel 1110, the top panel 1170, and the bottom panel 1190 are respectively constituted by the inner panel surfaces of the

inner panels

1120A, 1130A, 1140A, 1150A, 1170A, and 1190A having a vacuum heat insulating material. Therefore, the

outer panels

1120B, 1130B, 1140B, and 1150B on which the metal support portion 1310 is disposed do not contact the heat insulating space 1300.

* Supplement the frame part. In the heat insulating container 1100 of FIGS. 1 and 2, the right panel 1120, the left panel 1130, and the front panel 1150 are respectively arranged at the upper and lower ends of the panel from the right end of the panel to the left end of the panel. A metal frame portion 1320 that extends continuously to the end. Front panel 1150 also includes a metal frame (not shown) that extends continuously from the right end of the panel to the left end of the panel near the center of the panel. Furthermore, the top panel 1170 includes a metal frame portion 1320 that continuously extends from one end of the panel to the other end at the upper, lower, left, and right ends of the panel. ing. The frame portion is arranged to support the load and suppress the breakage of the vacuum heat insulating material when it is applied from the lateral direction when the heat insulating container 1100 is transported or stored. Furthermore, it can also serve as a cross beam that transmits the load from the top surface side to the metal support portion 1310. However, the presence of the frame portion is not limited, and the frame portion may not be provided. Further, the use of the metal frame portion is not limited, and an organic polymer frame portion mainly composed of an organic polymer material may be used. As shown in FIGS. 1 and 2, by disposing the metal frame portion 1320 on the outer panel, the metal frame portion 1320 does not come into contact with the heat insulating space 1300, so that it is possible to suppress a decrease in the heat insulating performance of the heat insulating container.

By providing the metal support portion 1310, the heat insulation container 1100 of the present example can support the load from the top surface received by the weight of the side panel and the heat insulation container in the lower stage of the two-stage heat insulation container. It can control that a heat insulating material is damaged. Moreover, the heat insulation container 1100 of this example forms the heat insulation space 1300 by the panel surface of the inner panel which has a vacuum heat insulating material, and prevents the metal support part 1310 from contacting the heat insulation space 1300, thereby insulating the heat insulation container. It can suppress that performance falls from the metal support part 1310. FIG.

As shown in FIG. 3, the heat insulating container 1100 of this example can be stored and transported with the heat insulating containers 1100A having the same specifications stacked on the upper side. The two-stage stacking operation of the heat insulating containers can be performed by the following procedure, for example. The pallet 1500 is placed on the floor of the work place with the surface on which the load is placed facing up. The bottom panel 1190 of the heat insulating container 1100 is disposed on the surface of the pallet 1500 on which the luggage is placed. Place the load on the bottom panel. The heat-insulated container 1100 in a disassembled state is assembled so that luggage is stored inside the container. Thereby, the heat insulation container 1100 of the assembly state in which the load loaded on the pallet 1500 was accommodated inside can be obtained. It should be noted that the assembly work of the heat insulating container 1100 in a disassembled state may be started before the luggage is deposited on the bottom panel, and the luggage may be stored inside the container after the assembly or / and during the assembly. By the same procedure, an insulated container 1100A in an assembled state in which the luggage placed on the pallet 1502 is housed can be obtained. Then, for example, using a forklift, the heat insulating container 1100A is loaded on the heat insulating container 1100.

Hereinafter, the heat insulating container according to the first invention of the present disclosure will be described in more detail with some embodiments.

(2) 1st Embodiment of 1st invention (a) Structure of heat insulation container 1st Embodiment of 1st invention is described. FIG. 4 is a diagram illustrating the heat insulating container 1100 according to the first embodiment. FIG. 5 is a diagram illustrating each component member of the heat insulating container 1100.

The heat insulating container 1100 is a container used for storage or transportation of articles that need to be kept cold or warm, such as frozen products and heated products. As shown in FIG. 4, the heat insulating container 1100 has a substantially rectangular parallelepiped shape and includes a pallet 1500 for conveyance. A claw hole 1501 penetrating the opposite side surface is provided on the side surface of the pallet 1500. By inserting the claw portion of the forklift into the claw hole 1501, the heat insulating container 1100 in which articles are stored can be moved together with the pallet 1500.

As shown in FIG. 4, the heat insulating container 1100 has a substantially rectangular parallelepiped shape surrounded by a pallet 1500, a bottom panel 1190, a front panel 1150, a left panel 1130, a back panel 1140, a right panel 1120, and a top panel 1170. The front panel 1150 faces the back panel 1140 in a state where the panel surface is parallel, and is adjacent to the top panel 1170, the bottom panel 1190, the left panel 1130, and the right panel 1120 in a vertical positional relationship. The left panel 1130 faces the right panel 1120 in a state where the panel surface is parallel, and is adjacent to the top panel 1170, the bottom panel 1190, the back panel 1140, and the front panel 1150 in a vertical positional relationship. . The back panel 1140 is adjacent to the top panel 1170, the bottom panel 1190, the right panel 1120, and the left panel 1130 in a vertical positional relationship.

The outer peripheral shape of the panel surface outside the side panel 1110 of the heat insulating container 1100 is four sides whose vertical width and horizontal width are 1000 mm or more and 1200 mm or less, respectively, when the heat insulating container 1100 in an assembled state is viewed from the top side, that is, the + Z direction. It is a shape. As much as possible, increasing the length of one side is advantageous not only for increasing the storage capacity in one insulated container, but also for loading platforms, containers, warehouses, etc. of transport machines such as trucks, railways, ships, and aircraft. It is also efficient for efficient storage in a limited space. The length of one side of the side panel of the heat insulating container is preferably approximated to the size of the pallet 1500 used together. The heat insulating container 1100 of this embodiment is suitable for a T11 type flat pallet whose JIS standard has a vertical width and a horizontal width of 1100 mm.

The front panel 1150 is a panel that can be partially opened and closed by a hinge 1101. Metal support portions 1310 extending in a direction parallel to the Z direction are disposed at the ends of the front panel 1150 in the + Y direction and the −Y direction. A frame portion 1320 extending in a direction parallel to the Y direction is disposed at the end portions of the front panel 1150 in the + Z direction and the −Z direction.

As shown in FIG. 5, the top panel 1170 has an outer panel 1170B and an inner panel 1170A. Front panel 1150, left panel 1130, back panel 1140, and right panel 1120 have

outer panels

1150B, 1130B, 1140B, and 1120B, and

inner panels

1150A, 1130A, 1140A, and 1120A, respectively. The bottom panel 1190 is constituted only by the inner panel 1190A. Each panel is disposed so that its inner panel faces the inner closed space side. A region surrounded by the inner panel surface of the inner panel is a heat insulating space 1300. *

(B) Assembling and disassembling the heat insulating container (i) Assembling the heat insulating box FIGS. 6 to 10 are diagrams illustrating an example of each assembling process when the heat insulating containers 1100 are assembled in order. First, as shown in FIG. 6, the bottom panel 1190 is laid on the pallet 1500. Next, the left panel 1130 is placed upright on the −Y direction side of the bottom panel 1190. The inner panel 1130A of the left panel 1130 is disposed on the + Y direction side which is the heat insulation space 1300 side.

Next, as shown in FIG. 7, the rear panel 1140 is placed upright on the −X direction side of the bottom panel 1190. The inner panel 1140A of the back panel 1140 is arranged on the + X direction side, which is the heat insulation space 1300 side.

Next, as shown in FIG. 8, the right panel 1120 is placed upright on the + Y direction side of the bottom panel 1190. The inner panel 1120A of the right panel 1120 is disposed on the −Y direction side, which is the heat insulation space 1300 side.

Next, as shown in FIG. 9, the front panel 1150 is placed upright on the + X direction side of the bottom panel 1190. The left side panel 1130, the back panel 1140, the right side panel 1120, and the front panel 1150 are respectively provided with side guide portions 1352 toward the pallet 1500 at the lower end portions of the panels. Adjacent to the sides. Thereby, even if the side panel 1110 receives a horizontal force from the outside, the panel is prevented from being displaced and sliding off the pallet 1500. The inner panel 1150A of the front panel 1150 is arranged on the −X direction side which is the heat insulation space 1300 side.

Finally, as shown in FIG. 10, the top panel 1170 is placed above the four side panels 1110, that is, on the + Z direction side, and the assembly of the heat insulating container 1100 is completed. Although the top panel 1170 is only covered by the four side panels 1110 by its own weight, the top panel guide 1351 facing the side panel side is attached to the end, so even if it receives vibration or the like during transportation, It is suppressed that the mounting position is shifted. In order to suppress the deviation, the connection using screws or the like used for joining the side panels 1110 may be additionally performed, or may be joined using a hook-and-loop fastener or the like.

In the above description of the assembly method, the side panel 1110 has been assembled in the order of the left panel 1130, the back panel 1140, the right panel 1120, and the front panel 1150. The right panel 1120, the back panel 1140, the left panel 1130, and the front panel 1150 can be assembled in this order, and the front panel 1150, the left panel 1130, the back panel 1140, and the right panel 1120 can be assembled in this order. is there.

(Ii) Disassembly of the heat insulation box The disassembly method can be basically performed in the reverse order of the assembly method. First, the reverse work of FIG. 10 is started, but the top panel 1170 is removed, then the front panel 1150 is removed as the reverse work of FIG. 9, and then the right panel 1120 is removed as the reverse work of FIG. . Further, as the reverse operation of FIG. 7, the rear panel 1140 is removed, and finally, as the reverse operation of FIG. 6, the left panel 1130 and the bottom panel 1190 are removed, thereby completing the disassembly operation.

As described above, when not used as an insulated container in which articles are placed in an insulated space, it is effective to store and transport the entire volume as small as possible.

FIG. 11 is a side view of the disassembled panels stacked in a specified order.

As shown in FIG. 11, in a state where the heat insulating container 1100 is disassembled, for example, a bottom panel 1190 composed of an inner panel 1190A is placed, and a left panel 1130 is disposed on the bottom panel 1130 on the lower side. The back panel 1140 is overlaid in the direction to become the outer panel 1130B, and the back panel 1140 is overlaid thereon in the direction to become the outer panel 1140B on the lower side and the inner panel 1140A on the upper side. A right panel 1120 is overlaid thereon with a lower side being an inner panel 1120A and an upper side being an outer panel 1120B. Further, a front panel 1150 is further placed on the lower side, an outer panel 1150B, and an upper side is an inner panel. The top panel 1170 is overlaid in the direction that becomes the inner panel 1170A on the lower side and the outer panel 1170B on the upper side. Even in the disassembled state, by arranging the bottom panel, the side panel, and the top panel in this order from the bottom to the top, the operator can easily understand when assembling.

Thus, the vacuum heat insulating material of the inner panel can be protected by stacking the panels so that the inner panels and the outer panels are adjacent to each other.

(C) Side panel (i) structure The side panel 1110 is demonstrated among each panel which comprises the heat insulation container 1100. FIG. The side panel 1110 includes a front panel 1150, a left panel 1130, a rear panel 1140, and a right panel 1120, which are four panels, and the left panel 1130, the rear panel 1140, and the right panel 1120 have the same structure. Therefore, the configurations of the back panel 1140 and the front panel 1150 will be sequentially described. FIGS. 12A and 12B are views of the rear panel 1140 as seen from above in a direction perpendicular to the panel surface. 12A is a view of the back panel 1140 as viewed from the −X direction side, which is the outside of the heat insulating container 1100. FIG. 12B is a view of the back panel 1140 as viewed from the + X direction side, which is the inside of the heat insulating container. FIG.

(Ii) Back Panel As shown in FIG. 12A, when the back panel 1140 is viewed from the outside of the heat insulating container 1100, the outside panel 1140B is visually recognized. The outer panel 1140B has two metal support portions 1310 and two frame portions 1320 arranged in a frame shape along the edge of the outer panel 1140B so as to surround the protective material 1322, the periphery of the protective material 1322. It is composed of Further, as shown in FIG. 12B, the rear panel 1140 has an inner panel 1140A visually recognized when viewed from the inside of the heat insulating container 1100, and the outer panel 1140A has an outer edge on the outer side of the outer panel 1140B. A part of the two metal support parts 1310 and the two frame parts 1320 arranged in the part are visually recognized. The inner panel 1140A mainly includes a heat insulating portion 1330 including a vacuum heat insulating material 1331 described later.

Each dimension of the outer periphery of the inner panel 1140A is smaller than each dimension of the outer panel 1140B, and the inner panel 1140A is disposed within the panel surface of the outer panel 1140B. Since the end portion of the inner panel is protected by the end portion of the outer panel, it is possible to prevent the vacuum heat insulating material of the inner panel 1140A from being damaged. Furthermore, by making the dimensional difference in consideration of the panel thickness, one end of the inner panel of the rear panel is brought into close contact with the end of the inner panel of the left panel, and the other end of the inner panel of the right panel is fixed. When closely attached to the end portion, the end portion of the outer panel of each panel can be configured to be in close contact, and the heat insulating property of the heat insulating space can be improved with the heat insulating container in the assembled state.

The structure of the inner panel 1140A will be described. FIG. 13A and FIG. 13B are cross-sectional views of the heat insulating portion 1330. 14A and 14B are cross-sectional views of the vacuum heat insulating material 1331 included in the heat insulating portion 1330. FIG.

FIG. 13A is a cross-sectional view showing an example of the structure of the heat insulating portion 1330. The heat insulation part 1330 is comprised from the heat insulation sheet | seat 1333 which wraps the vacuum heat insulating material 1331, the foam heat insulating material 1332 which surrounds both one and end surfaces of the main surface of the vacuum heat insulating material 1331, and these outer periphery. Since the foam heat insulating material 1332 is disposed on both sides of the end surface of the vacuum heat insulating material 1331, compared with the case where the foam heat insulating material 1332 is not disposed on both sides of the end surface of the vacuum heat insulating material 1331 and is a space. Will improve. The vacuum heat insulating material 1331 is comprised from the core material 1331a and the exterior | packing material 1331b. Since the vacuum heat insulating material 1331 cannot maintain a vacuum when the exterior material 1331b is damaged and cannot obtain a desired heat insulating property, the vacuum heat insulating material 1331 has a foam heat insulating material 1332 on the heat insulating space side. Is arranged. Thereby, when the articles | goods put in the heat insulation space collide, the danger that the vacuum heat insulating material 1331 will be damaged can be reduced. In addition, in the structure of Fig.13 (a), the vacuum heat insulating material 1331 is protected by the outer side panel arrange | positioned on the opposite side to heat insulation space. In addition, although not shown in figure, the protective base material mentioned later may be arrange | positioned on the opposite side to the heat insulation space of the vacuum heat insulating material 1331.

When forming the heat insulating portion 1330 shown in FIG. 13A, it is not always necessary to set the vacuum heat insulating material 1331 in the mold and then integrally form the foam heat insulating material 1332 by injection molding. A method of joining the processed materials later with an adhesive or the like is also acceptable. Moreover, since the usage-amount of a foam heat insulating material can be reduced, the thickness of heat insulation part itself can be made thin and an accommodation volume can be taken large. Furthermore, there is flexibility in a manufacturing method such as separately making and keeping the vacuum heat insulating material 1331 and the foam heat insulating material 1332, and maintenance is also improved, such as easy replacement of the vacuum heat insulating material. The vacuum heat insulating material 1331 and the foam heat insulating material 1332 may be fixed using an adhesive. When fitted without using an adhesive, the vacuum heat insulating material 1331 can be configured to be removable from the foam heat insulating material 1332. The vacuum heat insulating material 1331 can also be configured to be removable from the foam heat insulating material 1332 by using a weak adhesive.

FIG. 13B is a cross-sectional view showing another example of the structure of the heat insulating portion 1330. The heat insulating part 1330 includes a vacuum heat insulating material 1331, a foam heat insulating material 1332 surrounding the vacuum heat insulating material 1331, and a heat insulating sheet 1333 surrounding the foam heat insulating material 1332, and the protective base material 1338 further includes a heat insulating material for the heat insulating part 1330. The sheet 1333 is surrounded. As the protective substrate, for example, a protective material made of an organic polymer for an outer panel described later can be used. Although not shown, the structure of the heat insulating portion 1330 includes a vacuum heat insulating material 1331, a foam heat insulating material 1332 surrounding the vacuum heat insulating material 1331, a protective base material 1338 surrounding the foam heat insulating material 1332, and a heat shield sheet 1333 surrounding the protective base material. You may be comprised from. As the protective substrate at this time, for example, a protective material made of an organic polymer for an outer panel described later can be used.

As shown in FIG. 14A, the vacuum heat insulating material 1331 is composed of a core material 1331a and a packaging material 1331b having gas barrier properties, and is a heat insulating material obtained by reducing the pressure inside the packaging material 1331b. FIG. 14B shows another example of the vacuum heat insulating material 1331. In FIG. 14A, gaps are formed at both ends inside the vacuum heat insulating material 1331. In FIG. 14B, no gap is formed. The air gap may or may not be formed depending on the manufacturing method of the vacuum heat insulating material 1331.

As the core material 1331a, a material used for a core material of a conventionally known vacuum heat insulating material can be used. For example, powder such as silica, foamed material such as urethane polymer, fiber body such as glass wool, etc. The porous body may be used.

The exterior material 1331b is a member that covers the outer periphery of the core material 1331a, and a flexible sheet in which a heat welding layer and a gas barrier layer are sequentially laminated from the core material may be used. As the gas barrier layer, a metal foil, a vapor deposition sheet having a vapor deposition layer formed on one surface of a resin sheet, or the like may be used. For example, aluminum can be used as the metal foil. For the vapor deposition layer, for example, aluminum, aluminum oxide, or silicon oxide can be used.

Gas barrier properties of the outer package 1331b is oxygen permeability ^0.5cc · m -2 · ^{day -1} or less, or may be inter alia ^0.1cc · m -2 · ^{day -1} or less. Further, the water vapor permeability ^0.2cc · m -2 · ^{day -1} or less, or may be inter alia ^0.1cc · m -2 · ^{day -1} or less.

The internal vacuum degree of the vacuum heat insulating material 1331 may be, for example, 5 Pa or less. The initial thermal conductivity of the vacuum heat insulating material 1331 is, for example, 15 mW · m ⁻¹ · K ⁻¹ or less, particularly 10 mW · m ⁻¹ · K ⁻¹ or less, particularly 5 mW · m ⁻¹ · K ^{−1 in a} 25 ° C. environment. It may be the following.

The foam heat insulating material 1332 can be disposed so as to be bonded adjacent to at least the main surface of the vacuum heat insulating material 1331 on the heat insulating space side. As the foam heat insulating material 1332, a known foam heat insulating material can be used, and for example, a polyurethane foam may be used.

The heat shield sheet 1333 can be disposed so as to cover the entire adjacent vacuum heat insulating material 1331 and foam heat insulating material 1332. Examples of the heat shielding sheet 1333 include a multilayer sheet including a metal foil, a vapor deposition sheet in which a vapor deposition layer is formed on one side of a resin sheet, and the like.

The heat insulating part 1330 can be configured such that the vacuum heat insulating material 1331 is visible from the outside. For example, providing the area | region where the foam heat insulating material 1332, the heat insulation sheet | seat 1333, and the protection base material 1338 do not exist, or making some or all of them transparent is mentioned. When the vacuum heat insulating material 1331 is damaged and abnormal deformation occurs on the surface, it is possible to check the state of damage to the vacuum heat insulating material without damaging the inner panel.

The structure of the outer panel 1140B will be described. As shown in FIG. 12A, the outer panel 1140B is arranged outside the inner panel 1140A, and is arranged in a frame shape along the end surface of the outer panel 1140B so as to surround the protective material 1322 and the protective material 1322. The two metal support portions 1310 parallel to the Z direction and the two frame portions 1320 parallel to the Y direction are configured.

The structure of the adjacent part of the back panel 1140 and the left panel 1130 will be described. FIGS. 15A and 15B are a plan view and a cross-sectional view of an adjacent portion between the back panel 1140 and the left panel 1130. FIG. 15A is a plan view of the heat insulating container 1100 viewed from the + Z direction when the top panel 1170 is removed. FIG. 15B is an enlarged view of a portion near the portion B in FIG. 15A cut at a cross section perpendicular to the Z direction at a screw coupling portion 1341 that couples adjacent portions of the rear panel 1140 and the left panel 1130. It is sectional drawing.

As shown in FIG. 15A, the side panel 1110 is arranged such that the end surface of the inner panel 1150A of the front panel 1150 and the panel surface of the inner panel 1130A of the left panel 1130 come into contact with each other, and the inner panel 1130A of the left panel 1130. The end surface of the rear panel 1140 and the inner panel 1140A of the rear panel 1140 are arranged so as to contact each other, and the end surface of the inner panel 1140A of the rear panel 1140 and the panel surface of the inner panel 1120A of the right panel 1120 are arranged to contact each other. The end surface of the inner panel of the right panel 1120 and the panel surface of the inner panel 1150A of the front panel 1150 are disposed so as to contact each other. In this way, each side panel 1110 has its inner panel in contact with two adjacent side panels at two locations, the end face and the panel face. Thereby, when each panel of the side panel 1110 is not provided with an opening / closing part, all of the dimensions, arrangement, and structure of the outer panel and the inner panel can be made the same, and the panel parts can be shared. Thereby, the stock of spare parts, such as an outer side, an inner side panel, a heat insulation part, and a vacuum heat insulating material, can be reduced, and parts exchange and repair work become easy. Also, in assembly work, for example, even if the left panel 1130, the back panel 1140, and the right panel 1120 are misplaced, they can be assembled without any problems and have no functional problems, improving workability and convenience. it can. Note that the arrangement of the panels is not limited to that shown in FIG.

The metal support portion 1310 will be described. As shown in FIG. 15B, the left panel 1130 has a heat insulating portion 1330 including a heat insulating sheet 1333, a foam heat insulating material 1332, and a vacuum heat insulating material 1331 from the + Y direction side to the −Y direction side. is there. On the −Y direction side, there is a protective material 1322 with an adhesive 1334 interposed therebetween, and the adhesive 1334 adheres and fixes the heat insulating portion 1330 and the protective material 1322. A partial support portion 1310a, which is a constituent member of the metal support portion 1310, is fitted and fixed to the tip of the protective material 1322 in the −X direction with a groove portion 1310c therebetween. The protective material 1322 and the partial support portion 1310a are constituent members of the outer panel 1130B. Further, as a configuration of the adjacent back panel 1140, there is a heat insulating portion 1330 including a heat insulating sheet 1333, a foam heat insulating material 1332, and a vacuum heat insulating material 1331 from the + X direction side to the −X direction side. The protective material 1322 is sandwiched between the adhesive 1334 on the −X direction side, and the adhesive 1334 adheres and fixes the heat insulating portion 1330 and the protective material 1322. The internal structure of the heat insulating part 1330 of the back panel 1140 is the same as that of the heat insulating part 1330 of the left panel 1130 described above. A partial support portion 1310b, which is a constituent member of the metal support portion 1310, is fitted and fixed to the front end of the protective material 1322 in the −Y direction with a groove portion 1310c therebetween. The partial support portion 1310b and the above-described partial support portion 1310a are connected to each other by a through-hole formed in a part thereof and a screw coupling portion 1341.

In FIG. 15B, the end surface 1330a of the heat insulating portion 1330 which is the end surface on the −X direction side of the inner panel 1130A of the left panel 1130 is the surface of the heat insulating portion 1330 which is the inner panel surface of the inner panel 1140A of the back panel 1140. The heat insulating property of the heat insulating space surrounded by the heat insulating portion 1330 is maintained. Further, the partial support portion 1310a of the left panel 1130 and the back panel 1140 partial support portion 1310b come into contact with each other to form an integrated metal support portion 1310. The metal support portion 1310 is perpendicular to the panel surface of the bottom panel 1190. In such a direction, it continuously extends from the end on the top panel 1170 side to the bottom panel 1190 side end to the top panel 1170 side end. Since the two partial support portions 1310a and 1310b are connected by the screw coupling portion 1341, the left panel 1130 and the rear panel 1140 are fixed without being displaced from each other, and necessary rigidity can be obtained. .

Thus, particularly when the heat insulating containers are stacked in two stages, the metal support portion 1310 supports the load applied in the vertical direction, whereby the risk of deformation and breakage of the vacuum heat insulating material can be reduced. For the metal support portion 1310, any metal material can be applied, and for example, iron, stainless steel, aluminum, aluminum alloy, copper, brass, zinc, or the like can be used. Aluminum or an aluminum alloy is preferable from the viewpoint of weight reduction, workability, and rigidity.

The protective material 1322 will be described. When used as a constituent member of the outer panel, the protective material 1322 protects the vacuum heat insulating material 1331 of the inner panel, and the metal support portion 1310 and the frame portion 1320 are disposed at the ends thereof, so that the entire outer panel is formed. The rigidity of the surface can be given. The protective material 1322 may be made of a material having low thermal conductivity in order to improve heat insulation. For example, organic polymer materials such as plywood, foam material, resin plate, embossed resin sheet, paperboard, ceramic members, and the like can be used. Plastic cardboard or cured wood can be used as a lightweight and relatively rigid material. The protective material 1322 is bonded to the heat insulating portion 1330 adjacent to the inner side, that is, the heat insulating space side, through the adhesive 1334. As the adhesive 1334, any liquid or solid adhesive can be used. Since a heat insulation part can be attached or detached easily, you may use a hook-and-loop fastener and a double-sided tape, for example. By making it possible to attach and detach, for example, when it is desired to replace only the vacuum heat insulating material 1331, it is not necessary to remove the entire panel from the heat insulating container 1100, and the maintainability is improved.

The frame unit 1320 will be described. As described with reference to FIGS. 12A and 12B, the frame portion 1320 extends from the right end of the outer panel to the left end of the outer panel at the upper and lower ends of the outer panel, respectively. It arrange | positions so that it may extend continuously. In this embodiment, the material of the frame portion 1320 is designed and simplified using the same member as that of the metal support portion 1310. However, the material is not necessarily the same, and other members such as polyvinyl chloride are not necessarily used. Various resins such as acrylonitrile / butadiene / styrene (ABS), polycarbonate, polyacetal, and phenol resin may be used.

The outer side panel 1140B of the rear panel 1140 can include a side guide part 1352 that is a protruding part toward the pallet 1500 so that the back panel 1140, which will be described later, does not slide off the pallet 1500.

(Iii) Left panel, left panel Since the left panel 1130 and the right panel 1120 have the same structure as the back panel 1140 described above, description of the left panel and the right panel is omitted.

(Iv) Front Panel The structure of the front panel 1150 will be described. FIG. 16A and FIG. 16B are diagrams in which the front panel 1150 is seen in a plan view from a direction perpendicular to the panel surface. FIG. 16A is a view of the front panel 1150 as viewed from the + X direction side, which is the outside of the heat insulating container 1100. FIG. 16B is a view of the front panel 1150 as viewed from the −X direction side, which is the inside of the heat insulating container. FIG. As shown in FIG. 16A, the front panel 1150 is centered on a straight line m parallel to the Y direction, and a front door portion 1161 that is a + Z direction side panel and a front plate portion 1151 that is a −Z direction side panel. It is divided into

The front door part 1161 is attached to the front plate part 1151 via a hinge 1101 arranged on a straight line m. The front door part 1161 opens and closes around the straight m axis with respect to the front plate part 1151. It is fixed so that it can rotate.

As shown in FIG. 16A, when the front door portion 1161 and the front plate portion 1151 are viewed from the outside of the heat insulating container 1100, the outer panel 1161B on the + Z direction side and the outer panel 1151B on the −Z direction side respectively.

Inner panels 1151 A and 1161 A are configured by a heat insulating portion 1330 including a vacuum heat insulating material 1331. In addition, on the outside of the outer peripheries of the

inner panels

1161A and 1151A, a metal support portion 1310 and a frame portion 1320 disposed at the end portions of the

outer panels

1161B and 1151B are visually recognized. The reason why the outer peripheral dimensions of the

inner panels

1161A and 1151A are smaller than the outer peripheral dimensions of the

outer panels

1161B and 1151B is the same as in the case of the back panel 1140 described above.

Further, the height of the outer panel of the front panel 1150 that can be opened and closed is lower than the height of the outer panel of the right panel, the rear panel, and the left panel. Therefore, the position of the end surface on the top surface side of the front panel is lower than the positions of the end surfaces of the right panel, the back panel, and the left panel in the assembled heat insulating container. Therefore, even if the end surface of the side panel is bent due to the weight of the top panel or other heat insulating containers, the opening and closing of the front panel is not hindered.

Further, in order to prevent damage to the inner panel 1190A caused by placing an article directly on the inner panel 1190A of the bottom panel 1190, an additional protective sheet may be disposed on the inner panel 1190A. The material of the protective sheet is not limited, but a resinous sheet such as a plastic cardboard sheet can be used.

(F) Pallet The pallet 1500 will be described. As the pallet 1500, a general one can be used. In the heat insulating container 1100 of the present embodiment, a light and rigid plastic T11 type flat pallet is used, but is not particularly limited. For example, plastic, metal such as aluminum and aluminum alloy, wooden, and cardboard And various sizes of pallets.

(G) Thermal insulation space The top panel 1170, the side panel 1110, and the bottom panel 1190 have

inner panels

1170A, 1110A, and 1190A, respectively. Each

inner panel

1170A, 1110A, 1190A is comprised from a heat insulation part. The inner panel 1110 A of the side panel 1110 includes a heat insulating part 1330 including a vacuum heat insulating material 1331. When these panels are in the assembled state, as described with reference to FIG. 5, a heat insulation space 1300 is formed as a substantially rectangular parallelepiped space by the panel surface of each inner panel. Since the periphery of the heat insulating space 1300 is surrounded by a heat insulating material, inflow and outflow of heat from the outside are limited, and heat insulating properties can be maintained.

(H) Coolant and heat insulating agent A form in which the cold insulating agent and the heat insulating agent are attached to the heat insulating container 1100 will be described. FIG. 20 is a view in which a pocket-shaped storage part 1401 is attached to the panel surface of the inner panel 1140A of the rear panel, and a cold insulating agent or a heat insulating agent 1402 is stored therein. Instead of the back panel or in addition to the back panel, other panels may be provided with a similar storage portion 1401 and a cold or heat insulating agent 1402. The storage portion 1401 may be directly bonded to the inner panel with an adhesive, or may be detachably bonded with a hook-and-loop fastener or a double-sided tape.

Depending on the use of the heat insulating container 1100 and the required content, a panel to which the storage unit 1401 for the cryogen or heat insulating agent 1402 is attached and a panel to which the storage part 1401 is not attached may be prepared and used separately. .

(3) Second embodiment of the first invention (a) Structure of a heat insulating container A second embodiment of the first invention will be described. FIG. 26 is a diagram illustrating a heat insulating container 1100B according to the second embodiment of the first invention. FIG. 27 is a diagram showing a state in which all doors are open in the heat insulating container 1100B according to the second embodiment of the first invention. FIG. 28 is a view of the front panel as viewed from the −X direction which is the inner side.

The main points different from the first embodiment of the first invention are that the top panel 1170 can be folded and that the front panel 1150 is in a closed state of the front door 1161 in a cross section perpendicular to the rotation center axis m. The boundary surface between the front plate portion 1151 and the front door portion 1161 is not on the same plane.

(B) Modification of Top Panel As shown in FIG. 21, the top panel 1170 is divided into two on a straight line n parallel to the Y direction, and has a first upper plate portion 1171 and a second upper plate portion 1181. ing. The first upper plate portion 1171 and the second upper plate portion 1181 are fixed so as to be rotatable around the straight n axis via a hinge 1102 disposed on the straight line n.

As shown in FIG. 22, with the first upper plate portion 1171 held on the side panel 1110, the second upper plate portion 1181 is rotated to the + Z direction side around the straight n-axis and opened or rotated to the original position. Close and open operation is possible. Alternatively, although not shown, the first upper plate portion 1171 can be opened and closed with the second upper plate portion 1181 held by the side panel 1110. Even after the heat insulating container 1100 is assembled, the second upper plate portion 1181 or the first upper plate portion 1171 can be opened to put in and out the article. For example, when luggage is loaded in front of the front panel 1150 and it is difficult to open the front panel 1150, the luggage can be taken in and out from the top side.

Furthermore, when disassembling the heat insulating container 1100B, the top panel can be removed from the side panel after the top panel is folded as shown in FIG. Further, when the heat insulating container 1100B is assembled, the side panel can be opened after the folded top panel is placed on the side panel as shown in FIG. Since the top panel can be raised and lowered with the top panel folded, work efficiency and safety can be improved.

(C) Modification of Front Panel As shown in FIG. 21, the front panel 1150 is divided into two on a straight line m parallel to the Y direction, and a front plate portion 1151 that is a fixed portion that does not open and close on the −Z direction side. And a front door 1161 on the + Z direction side that can be opened and closed by rotating in the + X direction side relative to the front plate part 1151 or closing the original plate around the axis of the straight line m. is doing. The front door part 1161 is attached to the front plate part 1151 via a hinge 1101 arranged on a straight line m. The front door part 1161 opens and closes around the straight m axis with respect to the front plate part 1151. It is fixed so that it can rotate freely.

Since the front panel 1150 includes the front plate portion 1151 and the front door portion 1161, the front door portion 1161 can be opened and articles can be taken in and out even after the heat insulating container 1100B is assembled. Even if other heat insulating containers are stacked on the upper stage of the heat insulating container 1100B, the front door portion 1161 allows the articles to be taken in and out.

The configuration of the front panel 1150 will be described. FIG. 23 is a view of the front panel 1150 as seen from the inside. When the front panel 1150 is viewed from the inside, the inner panel 1161A is visible on the + Z direction side, and the inner panel 1151A is visible on the −Z direction side.

1161B and 1151B (not shown) are visually recognized.

The arrangement of the

inner panels

1151A and 1161A in the Z direction is such that the boundary surface between the

inner panels

1151A and 1161A is shifted in the + Z direction from the straight line m that is the rotation center axis of the front door portion 1161. Thus, in a state where the front door portion 1161 is opened, a plurality of stepped steps are generated at the end portions near the adjacent portions of the front plate portion 1151 and the front door portion 1161.

FIG. 24 is a cross-sectional view cut at the position of the arrow EE shown in FIG. The front plate portion 1151 is joined to the heat insulating sheet 1333, the foam heat insulating material 1332, and the heat insulating portion 1330 which are made of the heat insulating sheet 1333, the vacuum heat insulating material 1331, and the heat insulating portion 1330 in this order as viewed from the −X direction via an adhesive 1334. The front plate portion opening / closing frame portion 1321a and the protection member 1322 which is a constituent member of the outer panel 1151B fitted to the front plate portion opening / closing frame portion 1321a with the groove portion 1321c interposed therebetween are arranged. Further, the front door portion 1161 has the same configuration, and the heat insulating sheet 1333, the foam heat insulating material 1332, and the heat insulating portion 1331 that are composed of the heat insulating sheet 1333 and the heat insulating portion in order from the front door as viewed from the −X direction.

(II) Second Invention The second invention of the present disclosure will be described.

(1) Overall thermal insulation container of the second invention of the present disclosure (a) Thermal insulation container of the second invention of the present disclosure The second invention of the present disclosure is a thermal insulation container that can be assembled and disassembled using a vacuum heat insulating material. is there. The heat insulation container is capable of forming a heat insulation space surrounded by the side panel, the top panel, and the bottom panel, and is in a disassembled state in which the heat insulation space is not formed from the assembled state in which the heat insulation space is formed. It is possible to change to the assembly state. The side panel, top panel, or bottom panel of the heat insulation container includes a panel that can be opened and closed, and includes a door that can be opened and closed by rotating around the linear rotation center with respect to the plate. . The panel that can be opened and closed includes an outer panel and an inner panel arranged on the panel surface of the outer panel on the heat insulating space side. The inner panel includes a heat insulating portion including a vacuum heat insulating material. The outer panel includes a metal door portion frame portion disposed on the door portion. In the assembled state, the door frame portion does not contact the heat insulation space formed by the panel surface on the heat insulation space side of the side panel, the panel surface on the heat insulation space side of the top panel, and the panel surface on the heat insulation space side of the bottom panel. .

(B) Demand for heat-insulating container of the second invention of the present disclosure Since it is common with the first invention, the description is omitted.

(C) Main structure of the heat insulating container The heat insulating container of the second invention of the present disclosure can form a heat insulating space surrounded by the side panel, the top panel, and the bottom panel, and the heat insulating space is It is possible to change from the assembled state to the disassembled state in which the heat insulation space is not formed, and to change from the disassembled state to the assembled state. Therefore, the heat insulation container of the second invention of the present disclosure can be stored and transported in a disassembled state reduced by disassembling and stacking when not in use.

The side panel, top panel, or bottom panel is provided with a panel that can be opened and closed with a door that can be opened and closed by rotating around a linear rotation center in an assembled state. Therefore, the workability of the heat insulating container according to the second invention of the present disclosure is improved by, for example, opening the panel when performing the work of putting in and out the article.

The openable and closable panel includes an outer panel and an inner panel disposed on the panel surface of the outer panel on the heat insulating space side, and the inner panel includes a heat insulating portion including a vacuum heat insulating material. Since vacuum insulation has good insulation performance even if it is small in thickness, the use of vacuum insulation can reduce the weight of the side panel, increase the storage capacity of the assembled insulation container, The heat-insulated container in a decomposed state can be made compact.

The outer panel of the openable / closable panel is provided with a metal door part frame part arranged in the door part in an assembled state. Since the metal door frame portion supports, for example, its own weight or a load from the top surface side, the heat insulation container of the second invention of the present disclosure has a good load resistance, enlarges the heat insulation container, Even when trying to stack, the risk of breakage of the vacuum insulation can be reduced.

The metal door frame part of the outer panel of the panel that can be opened and closed is in the assembled state on the panel surface on the heat insulation space side of the side panel, the panel surface on the heat insulation space side of the top panel, and the heat insulation space side of the bottom panel. It does not contact the heat insulating space formed by the panel surface. Therefore, it can suppress that heat is transmitted through a metal door part frame part, and the heat insulation performance of a heat insulation container falls.

From the above, the heat insulating container of the second invention of the present disclosure is a heat insulating container that uses a vacuum heat insulating material and can be assembled and disassembled, and can obtain good load resistance and heat insulating performance.

(D) Ancillary structure of the heat insulating container In the heat insulating container, the side panel, the top panel, or the bottom panel includes a plate portion that forms a wall surface in the assembled state, and the door portion includes the plate The outer panel includes a metal plate frame portion disposed on the plate portion, and the plate frame portion is in the assembled state, the side panel. It is good also as what does not contact the said heat insulation space formed by the panel surface by the side of the said heat insulation space of the said, the panel surface by the side of the heat insulation space of the said top panel, and the panel surface by the side of the said heat insulation space of the said bottom panel. In addition to the metal door part frame part arranged in the door part, by providing the metal plate part frame part also on the plate part side, the strength of the panel that can be opened and closed is increased, and as a heat insulating container Improve load capacity. Furthermore, the metal door part frame part and the metal plate part frame part may be configured to contact each other in the assembled state when the door part is closed in the assembled state. By arranging the metal door frame part and the metal plate frame part in contact with each other, the external force load from the panel itself and other panels that can be opened and closed, from the upper side when stacked in two stages The load portion and the like can be supported by the door portion frame portion and the plate portion frame portion that are in contact with each other, and the load resistance can be increased.

The plate part and the door part may be arranged on the same surface side of the heat insulating container when the door part is closed in the assembled state, or may be arranged on different surface sides of the heat insulating container. If they are arranged on the same side, the strength and rigidity of the panel that can be opened and closed will increase, and the panel will be difficult to deform. Reduces the risk of In addition, when arranged on different surfaces, for example, if the door frame portion and the plate frame portion are in contact with each other, the external force load can be distributed to a plurality of panels, and the resistance of one panel can be reduced. Even if the loadability is low, deformation of the panel and the heat insulating container can be suppressed. As a result, the rigidity of the heat insulating container as a whole can be improved, and the risk of breakage of the vacuum heat insulating material can be reduced.

In the heat insulating container, the side panel may include a plate portion constituting a wall surface, and a door portion that can be opened and closed by rotating with respect to the plate portion around a linear rotation center. When the orthogonal cross section is viewed, the boundary surface between the plate portion and the door portion in the closed state of the door portion may not be on the same plane. Heat transfer through the boundary between the plate portion and the door portion is suppressed, and the heat insulating performance of the heat insulating container is improved. Further, the position where the outer panel on the plate part side and the outer panel on the door part side are in contact with the position where the inner panel on the plate part side and the inner panel on the door part side are arranged is shifted, The boundary surfaces may not be on the same plane, and may be bent, for example. Since the inner panel on the plate part side or the inner panel on the door part side covers the position where the outer panel on the plate part side and the outer panel on the door part side contact, more heat transfer through the boundary between the plate part and the door part Can be suppressed.

The side panel 2110 includes a right panel 2120, a left panel 2130, a back panel 2140, and a front panel 2150. Each of the side panel 2110, the top panel 2170, and the bottom panel 2190 is a heat insulating panel including a heat insulating portion including a vacuum heat insulating material as described later. In this example, the top panel 2170 and the bottom panel 2190 include a heat insulating portion including a vacuum heat insulating material, but this is not a limitation. For the heat insulating portions of the top panel 2170 and the bottom panel 2190, for example, a heat insulating material that is not a vacuum heat insulating material such as a foam heat insulating material may be used. As shown in FIG. 27, the right panel 2120, the left panel 2130, the back panel 2140, and the front panel 2150 that constitute the side panel 2110 are all vertically centered about a point that is approximately half the height of each panel. The structure is divided into two. The lower half of each panel is a plate portion fixed to the heat insulating container 2100, and the upper half is a door portion attached to the plate portion so as to be opened and closed by a hinge. The top panel 2170 is also divided into two parts, the front side and the back side, about a point that is approximately half the length of the panel in the depth direction. It is attached to the back half plate part so that it can be opened and closed by a hinge. However, as will be described later, the back half plate portion can be opened and closed with respect to the front half door portion.

As shown in FIG. 28, the right panel 2120 is provided with a metal plate frame portion 2410 extending in the lateral direction at the upper end portion of the plate portion constituting the lower half side, and at the lower end portion of the door portion constituting the upper half side. A metal door portion frame portion 2420 extending in the lateral direction is provided, and the plate portion frame portion 2410 and the door portion frame portion 2420 are in contact with each other along a boundary line between the plate portion and the door portion. Further, since the hinge 2101 is attached to both the plate portion frame portion 2410 and the door portion frame portion 2420, the door portion of the right panel 2120 can be rotated and opened with respect to the plate portion. . Although not shown, the left panel 2130, the back panel 2140, and the front panel 2150 are also provided with a plate portion and a door portion that can be opened and closed with respect to the plate portion. The top panel 2170 is also provided with a plate portion frame portion 2410 and a door portion frame portion 2420 in the vicinity of the boundary line between the plate portion and the door portion.

The right panel 2120 and the left panel 2130 include a support part 2310 and a frame part 2320. The support portion 2310 as a vertical frame and the frame portion 2320 as a horizontal frame constitute the entire frame of the outer panel of each panel. Although not shown, the back panel 2140 and the front panel 2150 are similarly provided with a support portion 2310 and a frame portion 2320. In this example, the area other than the frame of the outer panel of each panel is provided with a protective material mainly composed of an organic polymer material described later, but this is not a limitation, and the entire outer panel The support part may be comprised and the other support part may be arrange | positioned in areas other than the frame of an outer side panel. Moreover, the ratio which a support part accounts in an outer side panel may be more or less than this example. The shape and arrangement of the support part are not particularly limited.

In addition, in this indication, in order to understand easily, the direction and position in the heat insulation container 2100 may be described as follows. The same applies to heat insulating

containers

2100A, 2100B, and 2100C described later.

The right panel 2120, the left panel 2130, the back panel 2140, the front panel 2150, and the top panel 2170 have a structure that can be partially opened and closed, and FIGS. 27 and 28 show a partially opened state. The heat insulating container 2100 in FIGS. 27 and 28 is in an assembled state of a quadrangular prism structure by closing each panel, and the heat insulating space surrounded by the side panel 2110, the top panel 2170, and the bottom panel 2190. Can be formed inside the container.

As shown in FIG. 29, the heat insulating container 2100 in the assembled state in which the heat insulating space 2300 is formed includes a right panel 2120, a left panel 2130, a rear panel 2140, a front panel 2150, and a top panel 2170 as a bottom panel 2190 and a pallet. By separating from 2500, it is possible to have a decomposition state in which the heat insulating space 2300 is not formed. Obviously, contrary to that shown in FIG. 29, it is possible to change to the heat insulating container 2100 in the assembled state by connecting the panels of the heat insulating container 2100 in the disassembled state.

As shown in FIG. 29, the front panel 2150, the left panel 2130, the back panel 2140, and the right panel 2120 that are the side panels 2110 are respectively an

outer panel

2150B, 2130B, 2140B, and 2120B and an

inner panel

2150A, 2130A, 2140A, And 2120A. The top panel 2170 includes an outer panel 2170B and an inner panel 2170A. The bottom panel 2190 includes an inner panel 2190A. Although not shown, each of the inner panels includes a heat insulating portion including a vacuum heat insulating material. Since the inner panel 2190A is protected by the pallet 2500, in this example, the bottom panel does not include the outer panel, but this is not a limitation, and the bottom panel may include the outer panel. . Thereby, it is possible to suppress the bottom panel from being pressed against the unevenness on the surface of the pallet 2500 by the load of the load, and the vacuum heat insulating material of the inner panel 2190A of the bottom panel from being damaged. Further, in this example, the top panel 2170 includes the outer panel 2170B, but this is not a limitation, and the top panel may not include the outer panel 2170B. When the top panel 2170 includes the outer panel 2170B, when the heat insulating containers are stacked in two stages, the vacuum heat insulating material included in the inner panel 2170A of the top panel 2170 of the lower cool box by the bottom face of the upper cool box. Can be prevented from being damaged.

As shown in FIGS. 27 to 29, each of the right panel 2120 is divided into two parts of approximately half size, a lower half side plate part fixed to the heat insulating container 2100, and a hinge with respect to the plate part. A door portion on the upper half side that can be rotated and opened. Further, the right panel 2120 includes a metal plate frame portion 2410 which is an upper end portion on the plate portion side and a metal door portion frame which is a lower end portion on the door portion side along a boundary line between the plate portion and the door portion. The plate portion frame portion 2410 and the door portion frame portion 2420 are in contact with each other when the heat insulating container 2100 is assembled. Although not shown, the same applies to the left panel 2130, the back panel 2140, and the front panel 2150. The top panel 2170 also includes a metal plate frame portion 2410 and a door frame portion 2420 that are in contact with each other along the boundary line between the back half and the front half.

The upper half side of each panel of the side panel 2110 can be opened and closed as a door portion, and a metal door frame portion 2420 is provided on the door portion. The door frame portion 2420 can increase the strength as a panel and the rigidity as a heat insulating container wherever the door frame portion 2420 is provided. However, in this embodiment, the door portion frame portion 2420 is outside the door portion closest to the rotation center of the door portion. The door frame portion 2420 is arranged so as to have an end along the edge. Taking the right panel 2120 as an example, a door frame portion 2420 having an end portion along the boundary line with the plate portion 2121 that is the outer edge of the door portion 2122 closest to the rotation center with respect to the plate portion 2121 is arranged. Yes. However, in FIG. 29, the frame portion 2320 is disposed at the uppermost portion of the door portion 2122, but this may be replaced with the door portion frame portion 2420. In this case, the door frame portion is configured to have an end portion along the outer edge of the door portion farthest from the rotation center of the door portion.

As described above, since the door portion of the panel that can be opened and closed opens and closes with respect to the heat insulating container, there are few joints with other panels, and the entire heat insulating container can be weakened. Therefore, it is effective to dispose a metal door frame having sufficient rigidity to reinforce this. As an effective arrangement place of the door part frame, the end part farthest from the rotation center, which is near the rotation center of the door part or vice versa, is effective. When the door is closed, when an external force load is applied to the heat insulation container, the door frame itself receives the load and supports the door part and the openable / closable panel, and the door part is adjacent to the plate part. In addition, the external force received by the door frame portion can be dispersed to the surroundings by contacting with the frame portion or the like of the adjacent panel, and the load can be supported by the entire heat insulating container.

Thus, when the door is closed, the door frame 2424 serves as a column or wall that supports the weight of the panel and the load from the top surface side, and suppresses damage to the vacuum heat insulating material. Further, when the plate portion frame portion 2410 is disposed at the end portion of the plate portion that is adjacent to the door portion frame portion 2420 as in the present embodiment, the door portion frame portion 2420 and the plate portion frame portion 2410 are provided. By contacting each other, forces can be transmitted to each other, and the effect of dispersing the load to the surroundings is enhanced, so that further load resistance and suppression of breakage of the vacuum heat insulating material can be achieved. In addition, the metal plate part frame part and door part frame part arranged on the top panel also act as a beam for the side panel, support the load from the upper stage in the two-stage stacking, and suppress the breakage of the vacuum insulation material To do.

In addition, as shown in FIGS. 27 to 29, the heat insulating space 2300 of the heat insulating container 2100 is in an assembled state in the inner panel surface of the side panel 2110, the inner panel surface of the top panel 2170, and the inner panel surface of the bottom panel 2190. It is formed by the panel surface. The panel surfaces on the heat insulation space 2300 side of the side panel 2110, the top panel 2170, and the bottom panel 2190 are respectively constituted by the inner panel surfaces of the

inner panels

2120A, 2130A, 2140A, 2150A, 2170A, and 2190A having a vacuum heat insulating material. Has been. The metal plate part frame part and the door part frame part constituting the boundary part between the plate part and the door part of each side panel or top panel are arranged on the

outer panels

2120B, 2130B, 2140B, 2150B and 2170B, respectively. Therefore, these metal plate | board part frame parts and door part frame parts do not contact the heat insulation space 2300, and can maintain favorable heat insulation. The plate portion frame portion and the door portion frame portion may be disposed on the bottom panel 2190, and in this case, the same applies. Although the details will be described later, when the hinge that rotatably attaches the door portion to the plate portion is made of a strong metal, there is no metal plate portion frame portion or door portion frame portion described above. In addition, the side panel may not be a two-panel configuration of the outer panel and the inner panel.

In the heat insulating container 2100 of this example, each panel can be partially opened and closed, and when the door portion is closed, the door portion and the plate are interposed at the boundary portion between the plate portion and the door portion via the metal door portion frame portion. When the parts are in contact with each other, the weight of each panel and the load from the top surface received by the heat insulation container at the bottom of the two-stage heat insulation container can be supported, and the vacuum heat insulating material can be prevented from being damaged. . Furthermore, in this example, by providing a metal plate part frame part on the plate part side, the door part frame and the plate part frame are in contact with each other, further improving the load resistance and suppressing the damage of the vacuum heat insulating material.

In the present disclosure, the front panel 2150, the left panel 2130, the back panel 2140, and the right panel 2120 are the

plate sections

2151, 2131, respectively. 2141 and 2121 and 2152, 2132, 2142 and 2122 which are door parts. Further, when the inner panels of the front panel 2150, the left panel 2130, the rear panel 2140, and the right panel 2120 are represented as 2150A, 2130A, 2140A, and 2120A, 2151A, 2131A, 2141A, which are the respective plate side inner panels, and 2121A and 2152A, 2132A, 2142A, and 2122A which are door side inner panels are pointed out. Similarly, when the outer panel is represented as 2150B, 2130B, 2140B, and 2120B, it means that 2151B, 2131B, 2141B, and 2121B on the plate portion side and 2152B, 2132B, 2142B, and 2122B on the door portion side are indicated. To do.

The same applies to the top panel 2170. The top panel 2170 corresponds to a first upper plate portion 2171 corresponding to a plate portion disposed on the back side and a door portion disposed on the front side thereof. Both or any one of the 2nd upper board parts 2172 shall be pointed out. Further, when the inner panel of the top panel 2170 is represented as 2170A, it refers to both or one of 2171A which is the first upper plate portion side inner panel and 2172A which is the second upper plate portion side inner panel, Similarly, when the outer panel is expressed as 2170B, it indicates both or one of 2171B which is the first upper plate portion side outer panel and 2172B which is the second upper plate portion side outer panel.

The structure of the side panel 2110 will be described using the front panel 2150 as an example. As shown in FIG. 31, the front panel 2150 is a panel that can be partially opened and closed by a hinge 2101. With a straight line m parallel to the Y direction passing through approximately half of the height direction, the −Z direction side half is the plate portion 2151, the + Z direction side half is the door portion 2152, and the door portion 2152 is The hinge 2101 is rotatably attached to a plate portion 2151 fixed to the heat insulating container 2100. Therefore, the door portion 2152 can be opened to the + X direction side, which is the front side, or can be returned to the original and closed. Each of the upper end portion of the plate portion 2151 and the lower end portion of the door portion 2152 is provided with a metal frame portion having a certain height and extending in the lateral direction. The plate portion side is a plate portion frame portion 2410, and the door portion side is a door portion frame portion 2420, which are in contact with each other along a straight line m that is a boundary line.

In the present disclosure, the contact between the plate part frame part and the door part frame part does not mean that the two frame parts are strictly in contact with each other in the assembled state of the heat insulation container. On top of the other insulated containers that have already stored the goods, or when the insulated containers are transferred by a forklift or the like with the pallets, or transported by truck, the insulated containers are caused by vibration and load. It also includes a state in which bending occurs and is arranged close enough to make temporary contact. In addition, the plate portion is not necessarily limited to a portion that does not move integrally with the heat insulating container body, and a door portion that can be rotatably opened and closed via a hinge is attached, and itself is attached to the heat insulating container body. On the other hand, even if it can be rotated with a hinge or can be translated with respect to the heat insulating container main body by a slide rail or the like, it can be included in the plate portion. Further, the plate portion and the door portion may be in the same panel, or may be configured in separate panels.

Further, support portions 2310 extending in the direction parallel to the Z direction are arranged at the end portions of the front panel 2150 in the + Y direction and the −Y direction. A frame portion 2320 extending in a direction parallel to the Y direction is disposed at the end portions of the front panel 2150 in the + Z direction and the −Z direction. The other side panels, ie, the left panel 2130, the back panel 2140, and the right panel 2120 have the same structure.

29, the top panel 2170 has an outer panel 2170B and an inner panel 2170A. Front panel 2150, left panel 2130, back panel 2140, and right panel 2120 have

outer panels

2150B, 2130B, 2140B, and 2120B, and

inner panels

2150A, 2130A, 2140A, and 2120A, respectively. The bottom panel 2190 is configured only by the inner panel 2190A. Each panel is disposed so that its inner panel faces the inner closed space side. A region surrounded by the panel surface inside the inner panel is a heat insulating space 2300.

(B) Front panel Among each panel which comprises the heat insulation container 2100, the front panel 2150 which is one of the side panels 2110 is demonstrated. The side panel 2110 includes a front panel 2150, a left panel 2130, a back panel 2140, and a right panel 2120, which are four panels, all having the same structure. FIG. 32A and FIG. 32B are diagrams of the front panel 2150 viewed in a plan view from a direction perpendicular to the panel surface. FIG. 32A is a view of the front panel 2150 as viewed from the + X direction side that is the outside of the heat insulating container 2100, and FIG. 32B is a view of the front panel 2150 from the −X direction side that is inside the heat insulating container. FIG.

As shown in FIG. 32 (a), the front panel 2150 is centered on a straight line m parallel to the Y direction, and a door portion 2152 which is a + Z direction side panel and a plate portion 2151 which is a −Z direction side panel. It is divided. The door portion 2152 is attached to the plate portion 2151 via a hinge 2101 disposed on a straight line m, and the door portion 2152 rotates so as to be able to open and close around the straight m-axis with respect to the plate portion 2151. It is fixed as possible.

As shown in FIG. 32 (a), when the door portion 2152 and the plate portion 2151 are viewed from the outside of the heat insulating container 2100, the outer panel 2152B on the + Z direction side and the outer panel 2151B on the −Z direction side are respectively visible. The The outer panel 2152B includes a protection member 2322, a support portion 2310 arranged in a frame shape along the end of the outer panel 2152B so as to surround the periphery of the protection material 2322, and various frame portions. The various frame parts are a door part front end frame part 2162 on the + Z direction side, a frame part 2320 indicated by a broken line on the back side thereof, and a metal door part frame arranged as a horizontal frame near the straight line m on the −Z direction side. Part 2420.

The outer panel 2151B is also composed of a protective member 2322, and two support portions 2310 and a frame portion arranged in a frame shape along the end of the outer panel 2152B so as to surround the periphery of the protective member 2322. The frame portion includes a metal plate portion frame portion 2410 disposed as a horizontal frame near the straight line m on the + Z direction side, and a frame portion 2320 on the −Z direction side.

32B, when viewed from the inside, the front panel 2150 has the inner panel 2152A visually recognized on the + Z direction side and the inner panel 2151A visually recognized on the −Z direction side. The inner panels 2151 A and 2152 A are composed of a heat insulating portion 2330 including a vacuum heat insulating material 2331. In addition, outside the outer peripheries of the

inner panels

2152A and 2151A, a support portion 2310 and a frame portion 2320 that are disposed at the end portions of the

outer panels

2152B and 2151B are visually recognized. The outer peripheral dimensions of the

inner panels

2152A and 2151A are smaller than the outer peripheral dimensions of the

outer panels

2152B and 2151B, respectively, and the

inner panels

2152A and 2151A are disposed within the panel surface of the

outer panels

2152B and 2151B. Since the edge part of an inner panel is protected by the edge part of an outer panel, it can prevent that the vacuum heat insulating material of an inner panel is damaged. Furthermore, by making the dimensional difference in consideration of the panel thickness, one end of the inner panel of the rear panel is brought into close contact with the end of the inner panel of the left panel, and the other end of the inner panel of the right panel is fixed. When closely attached to the end portion, the end portion of the outer panel of each panel can be configured to be in close contact, and the heat insulating property of the heat insulating space can be improved with the heat insulating container in the assembled state.

When the left panel 2130 and the right panel 2120 adjacent to the left and right of the front panel 2150 are panels that do not partially open and close like the front panel 2150, the height of the outer panel of the front panel 2150 that can be opened and closed is The height of the outer panels of the left panel 2130 and the right panel 2120 may be lower. In this case, the position of the end surface on the top surface side of the front panel 2150 is lower than the positions of the end surfaces of the left surface panel 2130 and the right surface panel 2120 in the heat insulating container in the assembled state. Therefore, even if the end surface of the side panel is bent due to the weight of the top panel 2170 or the weight of another heat insulating container when stacked in two stages, the opening and closing of the front panel 2150 is not hindered.

The structure of the inner panel 2150A will be described. The inner panel 2150A is divided into an inner panel 2151A of the plate portion 2151 and an inner panel 2152A of the door portion 2152, as shown in FIG. The

inner panels

2151A and 2152A are constituted by a heat insulating portion as described later. 33 (a) and 33 (b) are cross-sectional views of the front panel 2150 taken along a cross section perpendicular to the Y direction at the arrow FF of the front panel 2150 of FIG.

FIG. 33A is a cross-sectional view of the front panel 2150 when the door portion 2152 is closed, and FIG. 33B is a cross-sectional view when the door portion 2152 is opened. In the present embodiment, as shown in FIG. 33A, the heat insulating portion 2330 is used as the inner panel 2151A of the plate portion 2151 and the inner panel 2152A of the door portion 2152. The heat insulating portion 2330 and the vacuum heat insulating material 2331, the foam heat insulating material 2332, and the heat shielding sheet 2333 constituting the heat insulating portion 2330, the heat insulating portion 1330, the vacuum heat insulating material 1331, and the foam heat insulating material in the description of FIG. 13 and FIG. It is the same material and configuration as the material 1332 and the heat shield sheet 1333.

33 (a), the heat insulating part 2330 constituting the inner panel 2151A of the plate part 2151 is arranged so that the foam heat insulating material 2332 is adjacent to the heat insulating space side of the heat insulating container 2100. By doing so, the risk of directly damaging the vacuum heat insulating material 2331 by reducing the article against the inner panel 2151 when the article is put into and taken out of the heat insulating container 2100 after assembly is reduced. Further, the + X direction side which is the outside of the inner panel 2151 is joined to a plate part frame portion 2410 which is a constituent member of the outer panel 2151B described later via an adhesive 2334, and the outer side of the vacuum heat insulating material 2331 is the plate part frame portion. Since it is protected by the protective material 2322 bonded to 2410, the vacuum heat insulating material 2331 is hardly damaged even when an external force load is applied. The same applies to the door portion 2152.

The outer panel 2150B is divided into an outer panel 2151B of the plate portion 2151 and an outer panel 2152B of the door portion 2152 as shown in FIG. The outer panel 2151B is provided with a protective material 2322, two left and right support parts 2310 arranged as a vertical frame along the edge of the outer panel 2152B surrounding the protective material 2322, and in the vicinity of the straight line m on the + Z direction side. It is composed of a metal plate part frame part 2410 arranged as a horizontal frame and a frame part 2320 on the −Z direction side. Further, the outer panel 2152B is a horizontal frame on the + Z direction side, two support portions 2310 on the left and right sides arranged as a vertical frame along the end of the outer panel 2152B surrounding the protective material 2322 and the protective material 2322. It is composed of a door front end frame portion 2162, a frame portion 2320 arranged on the back side thereof, and a metal door portion frame portion 2420 arranged as a horizontal frame near the straight line m on the −Z direction side.

Also, as shown in FIG. 33 (a), the protective member 2322, which is a constituent member of the outer panel 2151B, is bonded to the + X direction side, which is the outer side of the inner panel 2151A including the heat insulating portion 2330 including the vacuum heat insulating material 2331. The plate portion frame portion 2410 is fitted and fixed at the upper end portion with the groove portion 2410c therebetween. In addition, a protective member 2322 that is a constituent member of the outer panel 2152B is disposed on the + X direction side, which is the outer side of the inner panel 2152A configured by the heat insulating portion 2330, and the door portion frame portion with the groove portion 2420c therebetween at the lower end portion thereof. 2420 is fitted and fixed. Further, a hinge 2101 is attached to the outside of the plate part frame part 2410 and the door part frame part 2420. As a result, the plate portion 2151 and the door portion 2152 are connected, and the door portion 2152 is rotatable with respect to the plate portion 2151, thereby opening the door portion 2152 in the + X direction side as shown in FIG. be able to.

In the state where the door 2152 is closed as shown in FIG. 33A, the plate frame 2424 positioned at the upper end of the plate 2151 and the door frame 2420 positioned at the lower end of the door 2152 are: The plate part frame part 2410 and the door part frame part 2420 which are metal members in this contact state support the weight of the door part 2152 and the load of the upper part when stacked in two stages. It is possible to suppress the deflection of the heat insulation container due to vibration during transportation.

When the door portion 2152 is closed, the plate portion frame portion 2410 and the door portion frame portion 2420 are separated from the heat insulating space by the heat insulating portion 2330 constituting the

inner panels

2151A and 2152A. Since the end surfaces are in contact with each other, the plate portion frame portion 2410 and the door portion frame portion 2420 do not contact the heat insulating space. As a result, even if a metal material having high thermal conductivity giving priority to strength is used as a constituent member of the plate portion frame portion 2410 and the door portion frame portion 2420, heat is transmitted to the heat insulating space surrounded by the heat insulating portion 2330. Since it is difficult, the fall of the heat insulation performance of the heat insulation container 2100 can be suppressed.

As the constituent members of the plate portion frame portion 2410 and the door portion frame portion 2420, metal materials in general can be applied. For example, iron, stainless steel, aluminum, aluminum alloy, copper, brass, titanium, zinc, or the like can be used.

Further, although it is not essential to provide the support portion 2310 and the frame portion 2320, as in the present embodiment, as a part of the outer peripheral frame of the plate portion 2151 and the door portion 2152, the vertical support portion 2310 and the horizontal direction portion are provided. If the frame portion is configured to be connected to the plate portion frame portion 2410 and the door portion frame portion 2420, the load resistance as a whole of the heat insulating container can be further improved. The support portion 2310 and the frame portion 2320 may or may not be the same material. For example, various materials such as metal materials, organic polymer materials, ceramic materials, and carbon fibers, and composite materials thereof. Is applicable. If it is a metal material, for example, iron, stainless steel, aluminum, aluminum alloy, copper, brass, titanium, zinc and the like can be used. As long as it is an organic polymer material, for example, acrylonitrile / butadiene / styrene (ABS), polycarbonate, acrylic resin, fiber reinforced plastic (FRP), or the like can be used.

The protective material 2322 will be described. When used as a constituent member of the outer panel, the protective material 2322 protects the vacuum heat insulating material 2331 of the inner panel, and also has a plate part frame part 2410, a door part frame part 2420, a support part 2310, and a frame at its ends. The portion 2320 can be disposed to provide rigidity as a surface as the entire outer panel. The protective material 2322 may be made of a material having low thermal conductivity in order to enhance heat insulation. For example, organic polymer materials such as plywood, foam material, resin plate, embossed resin sheet, paperboard, ceramic members, and the like can be used. Plastic cardboard or cured wood can be used as a lightweight and relatively rigid material. The protective material 2322 is bonded to the heat insulating portion 2330 adjacent to the inside, that is, the heat insulating space side, through the adhesive 2334. As the adhesive 2334, an arbitrary liquid or solid adhesive can be used. For example, a hook-and-loop fastener or a double-sided tape may be used so that the heat insulating portion can be easily attached and detached. By making it possible to attach and detach, for example, when it is desired to replace only the vacuum heat insulating material 2331, it is not necessary to remove the entire panel from the heat insulating container 2100, and maintenance is improved.

(C) Left panel, right panel, rear panel Since the left panel 2130, the rear panel 2140, and the right panel 2120 other than the front panel 2150 have the same configuration as the front panel 2150, description of each panel is omitted. Next, the joining state of the panels will be described by taking the structure of the adjacent portion between the back panel 2140 and the left panel 2130 as an example.

34 (a) and 34 (b) are a plan view and a cross-sectional view of an adjacent portion between the back panel 2140 and the left panel 2130. FIG. 34A is a plan view of the heat insulating container 2100 viewed from the + Z direction when the top panel 2170 is removed. FIG. 34 (b) shows an enlarged view of the vicinity of the G portion in FIG. 34 (a), cut at a cross section perpendicular to the Z direction at the location of the screw coupling portion 2341 that couples the adjacent portion of the rear panel 2140 and the left panel 2130. It is sectional drawing.

As shown in FIG. 34A, the side panel 2110 is arranged such that the end surface of the inner panel 2150A of the front panel 2150 and the panel surface of the inner panel 2130A of the left panel 2130 come into contact with each other, and the inner panel 2130A of the left panel 2130. The end surface of the rear panel 2140 and the inner panel 2140A of the rear panel 2140 are arranged so as to contact each other, and the end surface of the inner panel 2140A of the rear panel 2140 and the panel surface of the inner panel 2120A of the right panel 2120 are arranged to contact each other. The end surface of the inner panel of the right panel 2120 and the panel surface of the inner panel 2150A of the front panel 2150 are disposed so as to contact each other. As described above, each side panel 2110 has its inner panel in contact with two adjacent side panels at two positions of the end surface and the panel surface. It is the expanded sectional view cut in the section perpendicular to the Z direction in the part of screw joint part 2341 to couple.

Thus, each of the side panels 2110 can have the same size, arrangement, and structure of the outer panel and the inner panel, and the panel parts can be shared. Moreover, the stock of spare parts, such as an outer side, an inner side panel, a heat insulation part, a vacuum heat insulating material, can be reduced, and parts replacement | exchange and repair work become easy. Even in the assembly work, for example, even if the left panel 2130, the back panel 2140, and the right panel 2120 are misplaced, they can be assembled without any problems, have no functional problems, and can improve workability and convenience. . The arrangement of each panel is not limited to that shown in FIG. 34 (a). For example, the arrangement may be such that the panel surface of the inner panel 2130A of the left panel is in contact with the end surface of the inner panel 2140A of the rear panel 2140. It is also possible to take a method.

The detailed structure of the support part 2310 will be described. As shown in FIG. 34 (b), the left panel 2130 has a heat insulating portion 2330 composed of a heat insulating sheet 2333, a foam heat insulating material 2332, and a vacuum heat insulating material 2331 from the + Y direction side to the −Y direction side. is there. On the −Y direction side, there is a protective material 2322 with an adhesive 2334 interposed therebetween, and the adhesive 2334 adheres and fixes the heat insulating portion 2330 and the protective material 2322. A partial support portion 2310a, which is a constituent member of the support portion 2310, is fitted and fixed to the tip of the protective material 2322 in the −X direction with a groove 2310c therebetween. The protective material 2322 and the partial support portion 2310a are constituent members of the outer panel 2130B.

Further, as a configuration of the adjacent back panel 2140, there is a heat insulating portion 2330 similar to the left panel 2130. On the −X direction side, there is a protective material 2322 with an adhesive 2334 interposed therebetween, and the adhesive 2334 adheres and fixes the heat insulating portion 2330 and the protective material 2322. A partial support portion 2310b, which is a constituent member of the support portion 2310, is fitted and fixed to the front end of the protective material 2322 in the −Y direction with a groove 2310c therebetween.

The heat insulating property of the heat insulating space surrounded by the heat insulating portion 2330 is maintained. Further, the partial support portion 2310a of the left panel 2130 and the rear panel 2140 partial support portion 2310b are in contact with each other to form an integrated support portion 2310. The support portion 2310 is in a direction perpendicular to the panel surface of the bottom panel 2190. Furthermore, it extends continuously from the end on the top panel 2170 side to the bottom panel 2190 side end to the top panel 2170 side end. Since the two partial support portions 2310a and 2310b are connected by the screw coupling portion 2341, the left panel 2130 and the rear panel 2140 are fixed without being displaced from each other, and necessary rigidity can be obtained. .

(D) Top panel The top panel 2170 will be described. 35 (a) and 35 (b) are views of the top panel 2170 as viewed from above in a direction perpendicular to the panel surface. FIG. 35 (a) illustrates the top panel 2170 outside the heat insulating container 2100. FIG. 35B is a view of the top panel 2170 as seen from the −Z direction side, which is the inside of the heat insulating container.

As shown in FIG. 35A, the top panel 2170 is divided into two on a straight line n parallel to the Y direction, and the first upper plate portion 2171 corresponding to the plate portion and the second upper plate corresponding to the door portion. Part 2172. The first upper plate portion 2171 and the second upper plate portion 2172 are connected to a straight line n via a hinge 2102 disposed on a straight line n parallel to the Y direction, which is a substantially half point of the depth in the X direction of the top panel. The shafts are fixed so as to be rotatable around each other. When viewed from the outside of the heat insulating container 2100, the top panel 2170 is visually recognized as an outer panel 2170B. The outer panel 2170B is divided into an outer panel 2171B of the first upper plate portion 2171 and an outer panel 2172B of the second upper plate portion 2172, and the outer panel 2170B is outside so as to surround the protective material 2322 and the protective material 2322, respectively. It is composed of four frame portions 2320 arranged in a frame shape along the end portion of the panel 2170B.

Are arranged so that both are in contact with each other along a straight line n.

Further, as shown in FIG. 35 (b), the top panel 2170 has an inner panel 2170A visually recognized when viewed from the inside of the heat insulating container, and a frame of the outer panel 2140B on the outer periphery of the inner panel 2170A. A part of the outer frame surrounded by the portion 2320 is visually recognized. The inner panel 2170 A is divided into an inner panel 2171 A of the first upper plate portion 2171 and an inner panel 2172 A of the second upper plate portion 2172, and each includes a heat insulating portion 2330 including a vacuum heat insulating material 2331. Each dimension of the outer periphery of the inner panel 2170A of the top panel is also made smaller than each dimension of the outer periphery of the outer panel 2170B, like the side panel.

The top panel 2170 is opened by rotating the second upper plate 2172 in the + Z direction around the straight n-axis with the first upper plate 2171 held on the side panel 2110, or rotated to the original position. It can be opened and closed. Alternatively, although not shown, the first upper plate portion 2171 can be opened and closed while the second upper plate portion 2172 is held on the side panel 2110. Even after the heat insulating container 2100 is assembled, the second upper plate portion 2172 or the first upper plate portion 2171 can be opened to load / unload the luggage. For example, when luggage is loaded in front of the front panel 2150 and it is difficult to open the front panel 2150, the luggage can be taken in and out from the top side.

Furthermore, when disassembling the heat insulating container 2100, the top panel can be detached from the side panel after folding the top panel as shown in FIG. Further, when the heat insulating container 2100 is assembled, the side panel can be opened after the folded top panel is placed on the side panel as shown in FIG. Since the top panel can be raised and lowered with the top panel folded, work efficiency and safety can be improved.

A state where the top panel 2170 is placed on the side panel 2110 will be described. FIG. 36A and FIG. 36B are a front view and a cross-sectional view regarding an adjacent portion between the top panel 2170 and the left panel 2130. FIG. 36A is a diagram showing the heat insulating container 2100 viewed from the + X direction when the front panel 2150 is removed. FIG. 36B is an enlarged cross-sectional view of the vicinity of the H portion in FIG.

In FIG. 36A, a left panel 2130, a top panel 2170, a right panel 2120, and a bottom panel 2190 are arranged on the panel surface of the inner panel 2130A of the left panel 2130, the end surface of the inner panel 2170A of the top panel 2170, The bottom panel 2190 is disposed so as to abut the end surface of the inner panel 2190A. The end surface of the inner panel 2170A of the top panel 2170 and the end surface of the inner panel 2190A of the bottom panel 2190 are arranged so as to contact the panel surface of the inner panel 2120A of the right panel 2120.

As shown in FIG. 36 (b), as the configuration of the left panel 2130, there is a heat insulating portion 2330 including a heat insulating sheet 2333, a foam heat insulating material 2332, and a vacuum heat insulating material 2331 from the + Y direction side to the −Y direction side. is there. On the −Y direction side, there is a protective material 2322 with an adhesive 2334 interposed therebetween, and the adhesive 2334 adheres and fixes the heat insulating portion 2330 and the protective material 2322. A frame portion 2320 is fitted and fixed to the front end of the protective material 2322 in the + Z direction with a groove 2320c therebetween. As a configuration of the adjacent top panel 2170, there is a heat insulating portion 2330 similar to the left panel 2130. There is a protective material 2322 across the adhesive 2334 on the + Z direction side, and the adhesive 2334 adheres and fixes the heat insulating portion 2330 and the protective material 2322. A frame portion 2320 is fitted and fixed to the leading end of the protective material 2322 in the −Y direction with a groove 2320c therebetween. On the −Y side of the frame portion 2320, a top surface guide portion 2351, which is a protruding portion toward the −Z direction, which is bonded and fixed by an adhesive 2335, is attached.

In FIG. 36 (b), a surface 2330b of the heat insulating portion 2330 which is a panel surface inside the inner panel 2130A of the left panel 2130 is a surface of the heat insulating portion 2330 which is an end surface on the −Y direction side of the inner panel 2170A of the top panel 2170. It is in contact with the end face 2330a and maintains the heat insulating property of the heat insulating space surrounded by the heat insulating portion 2330. The top panel 2170 is placed on the upper side of the left panel 2130, that is, on the + Z direction side, and is in contact with the left panel by its own weight, but the placement position does not shift along the plane perpendicular to the + Z direction. The positional deviation is regulated by the top surface guide portion 2351. However, as the left panel 2130 in FIG. 36B, the side panel on which the top surface guide portion 2351 protrudes downward interferes with the top surface guide when attempting to open the door portion 2132. Before opening the door portion, it is necessary to open either the first upper plate portion 2171 or the second upper plate portion 2172 of the top panel 2170 first so that the top surface guide does not interfere.

Although not shown in the drawings, the description of the adjacent portion between the left panel 2130 and the top panel 2170 is as follows: the back panel 2140 and the top panel 2170, the right panel 2120, the top panel 2170, the front panel 2150, and the top panel. Is also common.

(E) Bottom Panel The bottom panel 2190 will be described. The bottom panel 2190 in the present embodiment is configured by an inner panel 2190A having the same structure as the inner panel 2170A in the top panel 2170. Since the bottom panel does not have a structure corresponding to the outer panel 2170B in the top panel 2170, the heat insulating container can be reduced in weight, the storage capacity of the assembled heat insulating container can be increased, and the disassembled state The heat insulation container can be made compact.

The state of the bottom panel 2190 placed on the pallet 2500 and the adjacent part of the left panel 2130 will be described. FIG. 37 is a cross-sectional view of the adjacent portion between the bottom panel 2190 and the left panel 2130, and is an enlarged cross-sectional view of the vicinity of the I portion in FIG.

In FIG. 37, a frame portion 2320 is fitted and fixed to the tip of the protective material 2322 constituting the outer panel 2130B of the left panel 2130 on the −Z direction side with a groove 2320c therebetween. A side guide part 2352 is attached to the outside of the frame part 2320 via an adhesive 2335 as a protruding part toward the pallet 2500. Since the side surface guide part 2352 is attached in a shape projecting downward along the side surface of the pallet 2500, the side surface panel 2110 is restricted from being displaced in the horizontal direction with respect to the pallet 2500. In FIG. 37, the side guide portion 2352 is joined to the frame portion 2320 with an adhesive 2335, but the joining means is not limited to the adhesive, and may be screw fastening, riveting, welding, or the like. Further, the surface 2330b of the heat insulating portion 2330 which is the inner panel surface of the inner panel 2130A of the left surface panel 2130 is in contact with the end surface 2330a of the heat insulating portion 2330 which is the end surface on the −Y direction side of the inner panel 2190A of the bottom panel 2190. The heat insulating property of the heat insulating space surrounded by the heat insulating portion 2330 is maintained.

Although not shown in the drawings, the description on the adjacent portion between the left panel 2130 and the top panel 2170 and the description on the adjacent portion between the left panel 2130, the bottom panel 2190, and the pallet 2500 are related. The same applies to adjacent portions.

Further, an additional protective sheet may be disposed on the inner panel 2190A in order to prevent damage to the inner panel 2190A caused by placing an article directly on the inner panel 2190A of the bottom panel 2190. The material of the protective sheet is not limited, but an organic polymer sheet such as a plastic cardboard sheet or a plate-like wood sheet can be used.

(F) Pallet The pallet 2500 will be described. As the pallet 2500, a general one can be used. In the heat insulating container 2100 of this embodiment, a light and rigid plastic T11 type flat pallet is used, but it is not particularly limited. For example, it is made of plastic, metal such as aluminum or aluminum alloy, wooden, or cardboard. And various sizes of pallets.

(G) Thermal insulation space The top panel 2170, the side panel 2110, and the bottom panel 2190 have

inner panels

2170A, 2110A, and 2190A, respectively. Each

inner panel

2170A, 2110A, 2190A is comprised of a heat insulating part. The inner panel 2110 A of the side panel 2110 includes a heat insulating part 2330 including a vacuum heat insulating material 2331. When these panels are in the assembled state, as described with reference to FIG. 29, the heat insulation space 2300 is formed as a substantially rectangular parallelepiped space by the panel surface of each inner panel. Since the periphery of the heat insulating space 2300 is surrounded by a heat insulating material, inflow and outflow of heat from the outside are limited, and heat insulating properties can be maintained.

(3) Second Embodiment of Second Invention (a) Structure of Insulated Container A second embodiment of the second invention will be described. FIG. 38 is a diagram illustrating a heat insulating container 2100B according to a second embodiment of the second invention of the present disclosure. In the heat insulating container 2100B, the door portion 2152 and the second door 2152 of the front panel 2150 and the top panel 2170 are illustrated. It is a figure which shows the state which the upper board part 2172 opened. The state in which the door is closed has the same appearance as FIG. 31 showing the first embodiment of the second invention. FIG. 39 is a cross-sectional view of the heat insulating container 2100B, in which the front panel 2150 is cut along a cross section perpendicular to the Y direction at the arrow FF of the front panel 2150 of FIG. 31, and FIG. FIG. 39B is a cross-sectional view when the door portion 2152 is opened.

The difference from the first embodiment of the second invention is that, in the cross section of the front panel 2150 orthogonal to the rotation center axis m, the boundary surface between the plate portion 2151 and the door portion 2152 in the closed state of the door portion 2152 is on the same plane. It is not.

(B) Modification of Front Panel As shown in FIG. 39A, the plate portion 2151 of the front panel 2150 includes a heat insulating sheet 2333, a foam heat insulating material 2332, and a vacuum heat insulating material 2331 sequentially from the −X direction. The heat insulating part 2330 to be configured, the plate part frame part 2410 joined to the heat insulating part 2330 via the adhesive 2334, and the constituent members of the outer panel 2151B fitted to the plate part frame part 2410 with the groove part 2410c therebetween. A protective material 2322 is arranged. Further, the door portion 2152 has the same configuration, and the same heat insulating portion 2330 as the plate portion 2151, door portion frame portion 2420 joined to the heat insulating portion 2330 with an adhesive 2334, and door portion frame portion 2420. A protective member 2322, which is a constituent member of the outer panel 2152B fitted with the groove 2420c therebetween, is disposed. The plate part frame part 2410 and the door part frame part 2420 are rotatably fixed by a hinge 2101.

Further, as shown in FIG. 39 (a), the boundary surface between the plate portion frame portion 2410 and the door portion frame portion 2420, which is a boundary surface between the outer panel 2151B of the plate portion 2151 and the outer panel 2152B of the door portion 2152 seen in a cross section. Since the boundary surface of each heat insulating portion 2330 which is the boundary surface between the inner panel 2151A of the plate portion 2151 and the inner panel 2152A of the door portion 2152 is formed at a different position in the Z direction, the plate portion 2151 and the door portion The boundary surface of 2152 is not on the same plane. Thereby, in the state which closed the door part 2152, inflow of the air from the outside will be prevented, and there exists an effect which maintains the heat insulation of heat insulation space. Also, in the vicinity of the boundary surface between the plate portion frame portion 2410 and the door portion frame portion 2420, and in the vicinity of the boundary surface of each heat insulating portion 2330, which is the boundary surface between the inner panel 2151A of the plate portion 2151 and the inner panel 2152A of the door portion 2152. Since each of them is a place where the heat insulation performance is lower than other parts, the heat insulation part including the vacuum heat insulating material 2331 in the heat insulation lowering region near the boundary surface between the plate part frame part 2410 and the door part frame part 2420 By arranging 2330, there is also an effect of suppressing a heat bridge caused by overlapping heat insulation performance degradation regions.

FIG. 39B is a diagram showing a state in which the door portion 2152 is opened. FIG. 40 is a perspective view showing a state in which the door portion 2152 is opened based on the cross section of FIG. As shown in both figures, when the door portion 2152 is opened, the end portions in the vicinity of the adjacent portions of the plate portion 2151 and the door portion 2152 are stepped down from the −X direction toward the + X direction stepwise. A warning tape 2103 is affixed to the stepped end. The material and design of the warning tape 2103 are not particularly limited, but may be configured by an elastic member such as an elastomer material or a sponge material so as to increase the effect of filling a gap or absorbing the impact of external force. The presence of the warning tape 2103 alerts the fingers to prevent pinching, and the article hits the inner panel 2152A protruding upward from the outer panel 2152B of the door portion 2152 during the loading / unloading operation of the article. The purpose is to call attention to prevent the vacuum heat insulating material of the inner panel 2152A from being damaged. Further, in the present embodiment, the place where the warning tape 2103 is affixed is when the door 2152 is opened from the X direction, that is, the front panel 2150, and when the heat insulating container 2100B is viewed from the side where the article is put in and out, The visibility of the warning tape 2103 is remarkably improved because of the step having a structure in which the step rises as it proceeds toward the −X direction.

Further, in the present embodiment, as a safety measure when opening the door portion 2152, as shown in FIG. 29, at the positions outside the plate portion 2151 and the door portion 2152 and facing each other when the door portion 2152 is opened, A buffer material 2104 is provided. Even if an operator pinches a finger when closing the door portion 2152, damage can be reduced.

(C) Modified example of the heat insulating container of the second invention In the embodiment and the modified examples so far, the rigidity of the entire heat insulating container is increased by providing a metal door frame part in the vicinity of the rotation center axis of the door part. Further, by providing a metal plate portion frame portion on the plate portion constituting the wall surface and arranging the plate portion frame portion and the door portion frame portion so as to contact each other, the rigidity of the entire heat insulating container is further increased. Explained to raise. However, if the hinge itself is made of high-strength metal that can be joined to the heat-insulating container or plate except for the door, the hinge itself can be opened and closed. Since it has an effect of reinforcing itself, the above-described metal plate frame portion and door frame portion are not necessarily required. In addition, when the hinge itself is made of metal, because of the structure, the arrangement position of the hinge is the outermost surface side of the heat insulating container which is the panel surface opposite to the heat insulating space of the side panel. There is no need for a two-panel configuration of an inner panel constituted by a heat insulating part including a vacuum heat insulating material and the like, and an outer panel arranged outside the inner panel.

The heat insulating container 2100C shown in FIG. 41 has a structure in which the front panel 2150 is divided into a lower plate portion 2151 and an upper door portion 2152, and the upper end side of the plate portion 2151 and the lower end side of the door portion 2152 are The door portion 2152 can be opened and closed with respect to the plate portion 2151 by being joined by a metal hinge 2107. Further, there are no metal plate part frame part or door part frame part at the end part of the plate part 2151 and the door part 2152 to which the metal hinge 2107 is fixed, and instead, a part where the metal hinge 2107 is screwed. Only, the plate-side hinge fixing member 2470 and the door-side hinge fixing member 2480 are partially arranged. Furthermore, the heat insulating container 2100C has no distinction between the inner panel and the outer panel, and has a single side panel.

When the metal hinge 2107 is fastened and fixed to the plate portion 2151 or the door portion 2152 with screws or the like, when the constituent member of the attachment portion is a heat insulating portion or plastic corrugated cardboard or the like, the metal hinge 2107 is attached to the metal hinge 2107 because the hardness of the member is low. There is a possibility that the plate portion and the door portion may be damaged from the screw fastening portion due to the applied external force load. The plate-side hinge fixing material 2470 and the door-side hinge fixing material 2480 need only have hardness and rigidity sufficient to fix the metal hinge 2107, and there is no particular limitation on the material. For example, it is not necessary to be a metal, and an organic polymer material, a ceramic material, carbon fiber, or the like having a certain degree of hardness and rigidity may be used. When a certain degree of hardness and rigidity can be obtained with only the side panel member, the plate-side hinge fixing member 2470 and the door-side hinge fixing member 2480 need not be provided.

FIG. 42 is a cross-sectional view of the heat insulating container 2100C of FIG. 42A is a cross-sectional view when the door portion 2152 is closed, and FIG. 42B is a cross-sectional view when the door portion 2152 is opened. As shown in FIG. 42A, the plate portion 2151 is provided with a heat insulating portion 2330 including a vacuum heat insulating material 2331, a foam heat insulating material 2332, a protective base material 2338, and a heat insulating sheet 2333 on the −Z direction side. A plate-side hinge fixing material 2470 is fitted and fixed at the + Z-direction end with a groove 2470c therebetween. The door portion 2152 has the same configuration as the plate portion 2151 in a vertically symmetrical manner, and a door portion side hinge fixing member 2480 is fitted and fixed with a groove portion 2480c at the −Z side end. A metal hinge 2107 is joined to the + X direction side of the contact portion between the plate-side hinge fixing member 2470 and the door-side hinge fixing member 2480 so as to couple them together.

Further, as shown in FIG. 42B, when the door portion 2152 is opened, the contact surface where the plate portion 2151 and the door portion 2152 come into contact with each other is formed by the protective base material 2338 and the heat shield sheet 2333. The vacuum insulation is protected. As described above, when the metal hinge 2107 is used, even when there is no metal plate part frame part or door part frame part and the side panel is not a two-panel configuration of the inner panel and the outer panel, the metal hinge 2107 is used. Depending on the strength and rigidity of the hinge, the load resistance of the entire heat insulating container including the plate portion and the door portion can be suitably obtained.

Side panel 3110 includes right panel 3120, left panel 3130, back panel 3140, and front panel 3150. Each of side panel 3110, top panel 3170, and bottom panel 3190 is a heat insulating panel including a heat insulating portion including a vacuum heat insulating material, as will be described later. In this example, the top panel 3170 and the bottom panel 3190 include a heat insulating portion including a vacuum heat insulating material, but this is not a limitation. For the heat insulating portions of the top panel 3170 and the bottom panel 3190, for example, a heat insulating material that is not a vacuum heat insulating material such as a foam heat insulating material may be used. Further, the right panel 3120 and the left panel 3130 include a non-metal support part 3310 and a frame part 3320. The non-metal support part 3310 as a vertical frame and the frame part 3320 as a horizontal frame constitute the entire frame of the outer panel of each panel. Although not shown, the back panel 3140 and the front panel 3150 are similarly provided with a non-metallic support portion 3310 and a frame portion 3320.

Moreover, the ratio which a nonmetallic support part accounts in an outer side panel may be more or less than this example. The shape of the non-metallic support part is not particularly limited as long as the non-metallic support part has a portion continuously extending from one end of the panel to the other end. Moreover, the non-metallic support part may exist on the inner panel side instead of the outer panel side, or may exist on both the outer panel and the inner panel.

The front panel 3150 and the top panel 3170 have a structure that can be partially opened and closed, and FIG. 43 shows a partially opened state. The heat insulating container 3100 in FIG. 43 is in an assembled state of a quadrangular prism structure by closing the front panel 3150 and the top panel 3170, and is surrounded by the side panel 3110, the top panel 3170, and the bottom panel 3190. It is possible to form an insulated space inside the container.

As shown in FIG. 44, the heat insulating container 3100 in the assembled state in which the heat insulating space 3300 is formed includes a right panel 3120, a left panel 3130, a rear panel 3140, a front panel 3150, and a top panel 3170 as a bottom panel 3190 and a pallet. By separating from 3500, it is possible to have a disassembled state in which the heat insulating space 3300 is not formed. Obviously, contrary to that shown in FIG. 44, it is possible to change to an insulated container 3100 in an assembled state by connecting the panels of the insulated container 3100 in an exploded state.

As shown in FIG. 44, the front panel 3150, the left panel 3130, the back panel 3140, and the right panel 3120, which are side panels 3110, are an

outer panel

inner panel

3150A, 3130A, 3140A, 3120A, respectively. Is provided. The top panel 3170 includes an outer panel 3170B and an inner panel 3170A. The bottom panel 3190 includes an inner panel 3190A. Although not shown, each of the inner panels includes a heat insulating portion including a vacuum heat insulating material. Since the inner panel 3190A is protected by the pallet 3500, in this example, the bottom panel does not include the outer panel, but this is not a limitation, and the bottom panel may include the outer panel. . Accordingly, it is possible to suppress the bottom panel from being pressed against the unevenness on the surface of the pallet 3500 by the load of the load, and the vacuum heat insulating material included in the inner panel 3190A of the bottom panel can be suppressed. Further, in this example, the top panel 3170 includes the outer panel 3170B, but this is not a limitation, and the top panel may not include the outer panel 3170B. Further, as will be described later, the side panel 3110, the top panel 3170, and the bottom panel 3190 may have an apparently or substantially one structure instead of the two-panel structure of the outer panel and the inner panel.

As shown in FIGS. 43 and 44, the right panel 3120, the left panel 3130, and the front panel 3150 are respectively located on the left and right ends of the panel from the top panel side end, which is the upper side of the panel, to the bottom of the panel. A non-metallic support portion 3310 that continuously extends to the end on the bottom panel side that is the side is provided. Although not shown, the same applies to the rear panel 3140. The non-metal support portion 3310 serves as a column or wall that supports the weight of the panel or the load from the top surface side. Thereby, it can suppress that a vacuum heat insulating material is damaged. The nonmetallic support portion 3310 is made of a nonmetal having a thermal conductivity of 10 W / (m · K) or less. Therefore, it can suppress that heat is transmitted through a nonmetallic support part and the heat insulation performance of a heat insulation container falls.

As shown in FIGS. 43 and 44, the heat insulating space 3300 of the heat insulating container 3100 is in the assembled state, the panel surface inside the side panel 3110, the panel surface inside the top panel 3170, and the panel surface inside the bottom panel 3190. It is formed by. The panel surfaces on the heat insulation space 3300 side of the side panel 3110, the top panel 3170, and the bottom panel 3190 are respectively constituted by the inner panel surfaces of the

inner panels

3120A, 3130A, 3140A, 3150A, 3170A, and 3190A having a vacuum heat insulating material. Has been.

* Supplement the frame part. 43 and 44, the right side panel 3120, the left side panel 3130, and the front panel 3150 are respectively provided at the upper and lower ends of the panel from the right end of the panel to the left end of the panel. A frame portion 3320 is provided that extends continuously. Front panel 3150 also includes a frame portion (not shown) that extends continuously from the right end of the panel to the left end of the panel near the center of the panel. Furthermore, the top panel 3170 includes a frame portion 3320 that continuously extends from one end of the panel to the other end at the upper, lower, left, and right ends of the panel. The frame portion is arranged to support the load and suppress the breakage of the vacuum heat insulating material when it is applied from the lateral direction when the heat insulating container 3100 is transported or stored. Furthermore, it can also serve as a cross beam that transmits the load from the top surface side to the non-metallic support portion 3310. Thereby, it can suppress that a vacuum heat insulating material is damaged. However, the presence of the frame portion is not limited, and the frame portion may not be provided. The frame part may be made of metal or non-metal. By making a flame | frame part non-metal whose heat conductivity is 10 W / (m * K) or less, it can suppress that heat | fever is transmitted through a non-metallic support part and the heat insulation performance of a heat insulation container falls.

The heat insulation container 3100 of this example can support the dead weight of the side panel by including the non-metal support portion 3310, and can prevent the vacuum heat insulating material from being damaged.

FIG. 45 shows the insulated container 3100 in the assembled state of this example. The assembly operation of the heat insulation container can be performed, for example, by the following procedure. The pallet 3500 is placed on the floor of the work place with the surface on which the load is placed facing up. The bottom panel 3190 of the heat insulating container 3100 is disposed on the surface on which the load of the pallet 3500 is placed. Place the load on the bottom panel. The thermal insulation container 3100 in a disassembled state is assembled so that the luggage is stored inside the container. Thereby, the heat insulation container 3100 of the assembly state in which the load loaded on the pallet 3500 was accommodated inside can be obtained. It should be noted that the assembly work of the heat insulating container 3100 in a disassembled state may be started before the luggage is deposited on the bottom panel, and the luggage may be stored inside the container after the assembly or / and during the assembly.

The nonmetallic support portion 3310 is made of a nonmetal having a thermal conductivity of 10 W / (m · K) or less. For example, at least one kind of resin selected from polyolefin resin, polystyrene resin, polyester resin, polycarbonate resin, and polyvinyl chloride resin can be used as a main component. Specific examples include, but are not limited to, polyethylene, polystyrene, polypropylene, polyethylene terephthalate (PET), polycarbonate, polyvinyl chloride, acrylonitrile / butadiene / styrene (ABS) resin, and the like. Moreover, the non-metallic support part 3310 can also have a fiber reinforced resin as a main component, for example, a glass fiber reinforced plastic and an aramid fiber reinforced plastic are mentioned. All of these exemplified materials have a thermal conductivity of about 0.1 to 1.0 W / (m · K). Further, for example, the non-metallic support part 3310 has a strength of the door frame part by increasing at least one kind of resin selected from a polyamide-based resin, a polyamide-imide resin, and a polyimide-based resin as a main component. The load resistance as a container can be improved. Specific examples include nylon, which is a polyamide containing an aliphatic skeleton, but is not limited thereto. An example of nylon is monomer cast nylon.

Measure methods of thermal conductivity are roughly divided into steady and unsteady methods. As a steady-state method, JIS A1412 defines a heat flow meter method for calculating a thermal conductivity by creating a steady heat flow in a sample and measuring a temperature distribution in the sample generated at that time. In addition, a disk heat flow meter method called a steady comparison method or a protective heat flow meter method is defined in ASTM E1530. On the other hand, as a non-stationary method, a high energy is instantaneously applied to a homogeneous material with a laser or the like, and the thermal conductivity is calculated based on the measured thermal diffusivity and specific heat. There are a hot wire method, a probe method, etc. for calculating the thermal conductivity from the amount of heat generated by the heater wire and the temperature rise of the sample by inserting a heater wire into the heat insulating material, sheet, or powder. The laser flash method is JIS H7801 or JIS R1611. In addition, the hot wire method and the probe method are defined in JIS R2616 and ASTM D5930.

The measurement method and numerical value of the thermal conductivity related to the present disclosure are based on the hot wire method of JIS R2616.

Next, when the non-metallic material as described above is used for the non-metallic support portion 3310, the cross-section obtained by cutting the non-metallic support portion 3310 along a plane perpendicular to the Z direction is rectangular. An appropriate range of the thickness in the direction perpendicular to the panel surface of the side panel and the lateral width parallel to the panel surface of the side panel will be described. For example, assuming that the non-metallic support part is a metal support part made of aluminum, the outer shape of the cross section cut by a plane perpendicular to the Z direction is a square with a side of 10 mm, the plate thickness is 2 mm, Considering the thickness and width for ensuring the bending rigidity equivalent to the bending rigidity of the metal support portion with the non-metal support portion 3310 when there is a square hollow portion with a side of 6 mm. In this case, the moment of inertia of the cross section of the aluminum metal support section is 4 squares of the square of one side of 0.01 m that is the outer shape of the cross section and 0.006 m of one side of the square that is a hollow part inside. The difference from the power is obtained and divided by 12, and the result is 7.25 × 10 ⁻¹⁰ (m ⁴ ). On the other hand, for example, assuming that the cross-sectional shape of the non-metallic support portion 3310 is a rectangle having a lateral width of 30 mm and a thickness of 10 mm and having no hollow portion inside, the cross-sectional secondary moment is the outer dimension of the cross-section. Multiply the short side 0.01m by the cube of the long side 0.03m and divide by 12. The result is 2.25 × 10 ⁻⁸ (m ⁴ ).

The bending rigidity of the metal support part and the non-metal support part is the product of the above-mentioned second-order moment and the Young's modulus of each material, so the ratio of the second-order moments of the non-metal support part and the aluminum metal support part. 31.0 is the Young's modulus of aluminum, which is 70.3 GPa (Science Chronology, 70th volume). This is divided by 31.0 to support a material with a Young's modulus of 2.26 GPa or more. If it uses as a part, it means that the bending rigidity equivalent to or more than said aluminum metal support part is obtained. As such a material, for example, polystyrene has a Young's modulus of 2.7 to 4.2 GPa (Science Chronology, 70th volume). When applied, it is possible to obtain bending rigidity equivalent to that provided with a 10 mm square hollow metal support, and to obtain excellent heat insulation by using a material having a lower thermal conductivity than metal.

In general, by increasing the thickness direction of the support portion, the difference between the outer volume of the heat insulation container and the capacity of the heat insulation space can be stored, and storage efficiency deteriorates. The thickness cannot be made extremely thick. For this reason, the upper limit in the thickness direction of the non-metallic support portion is considered to be approximately 30 mm, and it is necessary to adjust the lateral width within the range to obtain a desired rigidity. From the above consideration, when the lateral width of the non-metallic support portion is less than 30 mm, the required Young's modulus of the non-metallic material is increased and it is difficult to select an appropriate material. In addition, when the width is extremely large such as exceeding 100 mm, even if the Young's modulus condition can be satisfied, it is difficult to select and process the member in terms of shape. The range is 30 mm or more and 100 mm or less. If it is this range, the non-metal support part can be processed satisfactorily without impairing the processability of the member, and the necessary rigidity can be obtained while maintaining the heat insulation. More preferably, the lateral width may be not less than 40 mm and not more than 60 mm. In this way, the selection range of the material for the non-metallic support portion is further expanded, the material processing suitability is improved, the cost of the member is reduced, and both heat insulation and rigidity can be ensured.

(IV) Fourth Invention The fourth invention of the present disclosure will be described.

(A) Insulated container of 4th invention of this indication 4th invention of this indication is a heat insulation container in which a vacuum heat insulating material is used and it can assemble and disassemble. The heat insulation container is capable of forming a heat insulation space surrounded by the side panel, the top panel, and the bottom panel, and is in a disassembled state in which the heat insulation space is not formed from the assembled state in which the heat insulation space is formed. It is possible to change to the assembly state. The side panel, top panel, or bottom panel of the heat insulation container includes a panel that can be opened and closed, and includes a door that can be opened and closed by rotating around the linear rotation center with respect to the plate. . The panel that can be opened and closed includes an outer panel and an inner panel arranged on the panel surface of the outer panel on the heat insulating space side. The inner panel includes a heat insulating portion including a vacuum heat insulating material. The outer panel includes a non-metallic door portion frame portion disposed on the door portion.

(B) Demand for heat insulating container according to the fourth invention of the present disclosure Since it is common with the first invention, the description is omitted.

(C) Main structure of the heat insulating container The heat insulating container of the present disclosure can form a heat insulating space surrounded by the side panel, the top panel, and the bottom panel, and the heat insulating space is formed. It is possible to change from the assembled state to a disassembled state in which no heat insulation space is formed, and to change from the disassembled state to the assembled state. Therefore, when not in use, the insulated container of the present disclosure can be stored and transported in a disassembled state that is reduced by disassembling and stacking.

The side panel, top panel, or bottom panel is provided with a panel that can be opened and closed with a door that can be opened and closed by rotating around a linear rotation center in an assembled state. Therefore, the heat-insulating container according to the present disclosure improves workability by, for example, opening the panel when performing an article loading / unloading operation.

The outer panel of the openable / closable panel is provided with a non-metallic door part frame part arranged in the door part in an assembled state. Since the non-metallic door frame portion supports, for example, its own weight or the load from the top surface side, the insulated container of the present disclosure has a good load resistance, even when trying to enlarge the insulated container. The risk of damaging the vacuum insulation can be reduced.

Also, the panel can be opened and closed with a heat insulating part including a vacuum heat insulating material, and a non-metallic hinge arranged on the door part may be provided. Even when the heat insulation container is enlarged when the panel is opened, the weight of the door can be supported.

From the above, the heat insulating container of the present disclosure is a heat insulating container that uses a vacuum heat insulating material and can be assembled and disassembled, and can obtain good load resistance and heat insulating performance.

(D) The incidental structure of a heat insulation container The heat conductivity of the said nonmetallic door part flame | frame part may be 10 W / (m * K) or less. In this case, since the door frame part is difficult to transmit heat, restrictions on the arrangement position and size of the door frame part are reduced, and the room for design and material selection is increased. For example, the door frame portion may be disposed in contact with the heat insulating space of the heat insulating container. Moreover, the plate part frame part mentioned later may also have the same thermal conductivity.

The non-metallic door frame portion may be mainly composed of at least one resin selected from polyolefin resins, polystyrene resins, polyester resins, polycarbonate resins, and polyvinyl chloride resins, or The fiber reinforced resin may be a main component. By selecting materials that are generally easy to obtain and process in this way, the design of the heat insulation container becomes easy and the cost can be reduced. Moreover, the plate | board part frame part mentioned later may also have the same material as a main component. Further, for example, the non-metallic support part 3310 has a strength of the door frame part by increasing at least one kind of resin selected from a polyamide-based resin, a polyamide-imide resin, and a polyimide-based resin as a main component. The load resistance as a container can be improved. Specific examples include nylon, which is a polyamide containing an aliphatic skeleton, but is not limited thereto. An example of nylon is monomer cast nylon.

In the heat insulating container, the side panel, the top panel, or the bottom panel includes a plate portion that forms a wall surface in the assembled state, and the door portion can be opened and closed by rotating with respect to the plate portion. And the said outer side panel may be equipped with the non-metallic board part frame part arrange | positioned at the said board part. In addition to the non-metallic door part frame part arranged at the door part, the non-metallic plate part frame part is also provided on the plate part side, thereby increasing the strength of the panel that can be opened and closed, and the heat insulating container. As a load resistance is improved.

The material of the non-metallic plate portion frame portion may be the same as the material of the non-metallic door portion frame, and the non-metallic door portion frame portion and the non-metallic plate portion frame portion. May be configured to contact each other in the assembled state when the doors are closed in the assembled state. The non-metallic door part frame part and the non-metallic plate part frame part are arranged so that they come into contact with each other. Can be supported by the door part frame part and the plate part frame part which are in contact with each other, and the load resistance can be increased.

The plate portion and the door portion may be disposed on the same surface side of the heat insulating container when the door portion is closed in the assembled state, or may be disposed on different surface sides of the heat insulating container. If they are arranged on the same side, the strength and rigidity of the panel that can be opened and closed will increase, and the panel will be difficult to deform. Reduces the risk of In addition, when arranged on different surfaces, for example, if the door frame portion and the plate frame portion are in contact with each other, the external force load can be distributed to a plurality of panels, and the resistance of one panel can be reduced. Even if the loadability is low, deformation of the panel and the heat insulating container can be suppressed. As a result, the rigidity of the heat insulating container as a whole can be improved, and the risk of breakage of the vacuum heat insulating material can be reduced.

Note that, since the inner panel 4190A is protected by the pallet 4500, in this example, the bottom panel does not include the outer panel, but this is not a limitation, and the bottom panel may include the outer panel. . Accordingly, it is possible to suppress the bottom panel from being pressed against the unevenness on the surface of the pallet 4500 by the load of the load, and the vacuum heat insulating material included in the inner panel 4190A of the bottom panel can be suppressed. In this example, the top panel 4170 includes the outer panel 4170B. However, this is not a limitation, and the top panel may not include the outer panel 4170B. When the top panel 4170 includes the outer panel 4170B, the strength and rigidity of the entire heat insulating container can be increased.

The door frame portion 4420 is arranged so as to have an end portion along the edge. Taking the right panel 4120 as an example, a door frame portion 4420 having an end along the boundary line with the plate portion 4121, which is the outer edge of the door portion 4122 closest to the rotation center with respect to the plate portion 4121, is arranged. Yes. However, in FIG. 48, the frame portion 4320 is disposed at the uppermost portion of the door portion 4122, but this may be replaced with the door portion frame portion 4420. In this case, the door frame portion is configured to have an end portion along the outer edge of the door portion farthest from the rotation center of the door portion.

As described above, since the door portion of the panel that can be opened and closed opens and closes with respect to the heat insulating container, there are few joints with other panels, and the entire heat insulating container can be weakened. Therefore, it is effective to dispose a non-metallic door frame having sufficient rigidity to reinforce this. As an effective arrangement place of the door part frame, the end part farthest from the rotation center, which is near the rotation center of the door part or vice versa, is effective. When the door is closed, when an external force load is applied to the heat insulation container, the door frame itself receives the load and supports the door part and the openable / closable panel, and the door part is adjacent to the plate part. In addition, the external force received by the door frame portion can be dispersed to the surroundings by contacting with the frame portion or the like of the adjacent panel, and the load can be supported by the entire heat insulating container. Furthermore, a heat insulation container can be reduced in weight by not making a door frame part metal.

Thus, the door frame portion 4420 serves as a column or wall that supports the weight of the panel and the load from the top surface side, particularly when the door is closed, and suppresses breakage of the vacuum heat insulating material. Further, when the plate portion frame portion 4410 is disposed at the end portion of the plate portion adjacent to the door portion frame portion 4420 as in the present embodiment, the door portion frame portion 4420 and the plate portion frame portion 4410 are provided. By contacting each other, forces can be transmitted to each other, and the effect of dispersing the load to the surroundings is enhanced, so that further load resistance and suppression of breakage of the vacuum heat insulating material can be achieved. Moreover, the non-metallic plate part frame part and door part frame part which are arrange | positioned at a top panel also play the role of the beam with respect to a side panel, and suppress the failure | damage of a vacuum heat insulating material.

Also, as shown in FIGS. 46 to 48, the heat insulating space 4300 of the heat insulating container 4100 is in an assembled state in the inner panel surface of the side panel 4110, the inner panel surface of the top panel 4170, and the inner panel surface of the bottom panel 4190. It is formed by the panel surface. The panel surfaces on the heat insulation space 4300 side of the side panel 4110, the top panel 4170, and the bottom panel 4190 are respectively constituted by the inner panel surfaces of the

inner panels

4120A, 4130A, 4140A, 4150A, 4170A, and 4190A having a vacuum heat insulating material. Has been. The non-metallic plate part frame part and the door part frame part constituting the boundary part between the plate part and the door part of each side panel or top panel are arranged on the

outer panels

4120B, 4130B, 4140B, 4150B and 4170B, respectively. Therefore, these non-metallic plate part frame part and door part frame part do not contact the heat insulating space 4300. However, since the plate part frame part and the door part frame part are made of non-metal which hardly causes heat conduction, they may be in contact with the heat insulating space 4300. The plate portion frame portion and the door portion frame portion may be disposed on the bottom panel 4190, and in this case, the same applies. In addition, although details will be described later, when the hinge that rotatably attaches the door portion to the plate portion is made of strong non-metal, the above-described non-metallic plate portion frame portion and door portion frame portion are The side panel may not be a two-panel configuration of the outer panel and the inner panel.

In the heat insulating container 4100 of this example, each panel can be partially opened and closed, and when the door portion is closed, at the boundary between the plate portion and the door portion, the door portion and the door portion via the non-metallic door portion frame portion. When the plate portions come into contact with each other, the weight of each panel can be supported, and the vacuum heat insulating material can be prevented from being damaged. Furthermore, in this example, by providing a non-metallic plate part frame part on the plate part side, the door part frame and the plate part frame come into contact with each other, further improving the load resistance and suppressing the breakage of the vacuum heat insulating material. An effect can be obtained.
