Description

  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.

  The heat insulation container which uses a vacuum heat insulating material and can be assembled and disassembled is disclosed in Patent Documents 1 to 3, for example.

  If the vacuum heat insulating material is broken and the internal vacuum state is broken, the heat insulating 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.

  However, when an insulation container is enlarged so that the entire package transported and stored on a pool pallet can be stored in the interior insulation space, and the large insulation containers are stacked in two stages, There was a possibility that the vacuum heat insulating material used in the lower heat insulating container might be damaged by the load.

  An object of the present disclosure is to obtain a good load resistance and heat insulation performance in a heat insulating container in which a vacuum heat insulating material is used and can be assembled and disassembled.

And it is possible to change from the assembled state where the heat insulating space is formed to a disassembled state where the heat insulating space is not formed, and from the disassembled state to the assembled state. The panel includes an outer panel and an inner panel disposed on a 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, and the outer panel is in the assembled state. A metal support portion that extends continuously from an end portion of the side panel on the top panel side to an end portion of the side panel on the bottom panel side, and the metal support portion is In the assembled state, 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.

1. Overall of Insulated Container of Present Disclosure (a) Insulated Container of Present Disclosure The present disclosure describes an insulated container that uses a vacuum heat insulating material and can be assembled and disassembled. 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 insulated containers according to the present disclosure Insulated containers are used for storage and transportation of articles that need to be kept cold or warm in, for example, the physical distribution field. 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.

  But if a heat insulation container becomes large, the heat insulation panel required for the heat insulation container will also become large, but a big heat insulation panel is heavy and becomes 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 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 includes an outer panel and an inner panel disposed on a 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 part 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 and the top surface side, the insulated container of the present disclosure has a good load resistance, even when the insulated container is enlarged and attempted to be stacked in two stages. The risk of damaging the vacuum insulation 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.

  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) 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 said heat insulation container may be equipped with the pallet, The said pallet may be arrange | positioned at the panel surface on the opposite side to the said heat insulation space of the said bottom face panel of the said heat insulation container. 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 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 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 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 said side panel of the said heat insulation container may be equipped with the protrusion part which goes to the said bottom panel side in the said assembly state in the edge part on the said bottom panel side. 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.

  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 outer peripheral shape and dimensions of the heat insulating container of the present disclosure are not particularly limited. As for the heat insulation container of this indication, each dimension may be a thing of a cm order, and one or more of each dimension may be a thing of 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 with a horizontal width of 1116 mm to 916 mm, a quadrilateral with 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.

  In the heat insulating container, the outer panel of the side panel has a portion not provided with the metal support portion, and the portion may be provided with a protective material made of organic polymer, The luggage stored in the heat insulating container may include a wireless communication device. When a wireless communication device such as an RF tag unit, which will be described later, is disposed, it is possible to suppress the metal support unit from obstructing radio wave transmission / reception of the wireless communication device. Note that the wireless communication device is not limited to an RF tag unit described later, and any wireless communication device that receives and transmits radio waves can be used. Examples include RFID devices, specific power-saving wireless devices, wireless LAN devices, Bluetooth devices (“Bluetooth” is a registered trademark), mobile phone devices such as 3G lines, and wireless devices that transmit information via LPWA networks such as LoRa. . Examples of the wireless communication device include a device that communicates with an external device by receiving and transmitting radio waves, and a device that communicates with an internal device such as a heat insulating container and a detection device installed therein by receiving and transmitting radio waves.

  The heat insulating container may include a wireless communication device that can be disposed on the side panel, and the wireless communication device is a plan view of a side panel on which the wireless communication device is disposed from the side surface. You may arrange | position in the position which does not overlap with the said metal support part. It can suppress that a metal support part inhibits transmission / reception of the electromagnetic wave of a radio | wireless communication apparatus. In addition, the heat insulating container may include a wireless communication device that can be disposed on the side panel, and the outer panel of the side panel includes a portion that does not include the metal support portion. The wireless communication device may be provided at a position overlapping the protective material when the side panel on which the wireless communication device is disposed is viewed from the side. May be. Radio waves can be transmitted and received through protective materials made of organic polymers. Moreover, the said heat insulation container may be equipped with the radio | wireless communication apparatus which can be arrange | positioned at the said top panel or the said side panel. Since the metal support portion is disposed on the side panel, it is possible to suppress the metal support portion from obstructing the transmission and reception of radio waves of the wireless communication device by disposing the wireless communication device on a panel other than the side panel. .

  The heat insulation container may include a wireless communication device that can be disposed on the side panel, and the wireless communication device is disposed between the outer panel of the side panel and the inner panel of the side panel. Also good. The risk of damage to the wireless communication device can be reduced.

  The heat insulating container may include a panel on which a wireless communication device is disposed and a replacement panel that is replaceable with the panel on which the wireless communication device is disposed and on which the wireless communication device is not disposed. In addition, the heat insulating container of the present disclosure is replaceable with a panel in which a storage unit that can store a cold insulating agent or a heat insulating agent is arranged and a panel in which the storage unit that can store a cold insulating agent or a heat insulating agent is arranged. In addition, a replacement panel in which a storage portion that can store a cold insulating agent or a heat insulating agent is not disposed may be provided. Since the insulated container of the present disclosure can be assembled and disassembled, these replacement panels can be used. By utilizing these replacement panels, it is possible to improve the efficiency of transportation and storage using the heat insulating container of the present disclosure. Note that the replacement panel may be any of a side panel, a top panel, and a bottom panel, and may be a panel that constitutes a part of these panels.

  The heat insulating container may include a conductive material in contact with the heat insulating space. Since the said heat insulation container of this indication is comprised so that a metal support part may not contact heat insulation space, there exists a possibility that it may become easy to generate static electricity inside a heat insulation container. Then, it can suppress that static electricity accumulate | stores inside the container of a heat insulation container with a electrically conductive material.

  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 arranged 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 insulation container may be arranged so 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 can be separated 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 an 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.

FIG. 3 is a diagram illustrating a state where an example of the heat insulating container of the present disclosure is stacked in two stages.

  As shown in FIG. 1, the heat insulating container 100 of this example includes a pallet 500 having a side panel 110, a top panel 170, a bottom panel 190, and a claw hole 501. The side panel 110 includes a right panel 120, a left panel 130, a back panel 140, and a front panel 150. Each of the side panel 110, the top panel 170, and the bottom panel 190 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 170 and the bottom panel 190 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 170 and the bottom panel 190, 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 120 and the left panel 130 include a metal support part 310 and a frame part 320. The metal support part 310 as a vertical frame and the frame part 320 as a horizontal frame constitute the entire frame of the outer panel of each panel. Although not shown, the back panel 140 and the front panel 150 are similarly provided with a metal support part 310 and a frame part 320. 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 100 may be described as follows.

  A direction perpendicular to the panel surface of the bottom panel 190 from the bottom panel 190 to the top panel 170 is defined as + Z direction or upward direction, and a direction opposite to the + Z direction is defined as −Z direction or downward direction. The + Z direction and / or the −Z direction may be simply referred to as the Z direction. Among the horizontal planes that are perpendicular to the + Z direction, a direction perpendicular to the panel surface of the back panel 140 from the back panel 140 toward the front panel 150 is defined as + X direction, and a direction opposite to the + X direction is defined as −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 130 to the right panel 120 perpendicular to the panel surface of the right panel 120 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 150 and the top panel 170 have a structure that can be partially opened and closed, and FIG. 1 shows a partially opened state. 1 is in an assembled state of a quadrangular prism structure by closing the front panel 150 and the top panel 170, and is surrounded by the side panel 110, the top panel 170, and the bottom panel 190. It is possible to form an insulated space inside the container.

  As shown in FIG. 2, the heat insulating container 100 in an assembled state in which the heat insulating space 300 is formed includes the right panel 120, the left panel 130, the rear panel 140, the front panel 150, and the top panel 170 with the bottom panel 190 and the pallet. By separating from 500, it is possible to have a disassembled state in which the heat insulating space 300 is not formed. Obviously, contrary to that shown in FIG. 2, it is possible to change to the heat insulating container 100 in the assembled state by connecting the panels of the heat insulating container 100 in the disassembled state.

  As shown in FIG. 2, the front panel 150, the left panel 130, the rear panel 140, and the right panel 120, which are the side panels 110, are the outer panels 150B, 130B, 140B, 120B, and the inner panels 150A, 130A, 140A, 120A, respectively. Is provided. The top panel 170 includes an outer panel 170B and an inner panel 170A. The bottom panel 190 includes an inner panel 190A. Although not shown, each of the inner panels includes a heat insulating portion including a vacuum heat insulating material. Note that, since the inner panel 190A is protected by the pallet 500, 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. . Thereby, it can suppress that a bottom surface panel is pressed by the unevenness | corrugation of the surface of the pallet 500 with the load of a load, and the vacuum heat insulating material which the inner side panel 190A of a bottom surface panel has is damaged. Further, in this example, the top panel 170 includes the outer panel 170B, but this is not a limitation, and the top panel may not include the outer panel 170B. When the top panel 170 includes the outer panel 170B, when the heat insulating containers are stacked in two stages, the vacuum heat insulating material included in the inner panel 170A of the top panel 170 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 120, the left panel 130, and the front panel 150 are respectively provided 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. It includes a metal support 310 made of metal that continuously extends to the end on the side of the bottom panel. Although not shown, the same applies to the back panel 140. The metal support 310 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 300 of the heat insulation container 100 is in an assembled state, the panel surface inside the side panel 110, the panel surface inside the top panel 170, and the panel surface inside the bottom panel 190. It is formed by. The panel surfaces on the heat insulation space 300 side of the side panel 110, the top panel 170, and the bottom panel 190 are respectively constituted by the inner panel surfaces of the inner panels 120A, 130A, 140A, 150A, 170A, and 190A having a vacuum heat insulating material. Therefore, the outer panels 120 </ b> B, 130 </ b> B, 140 </ b> B, and 150 </ b> B on which the metal support 310 is disposed do not contact the heat insulating space 300.

  It supplements about a frame part. In the heat insulating container 100 of FIGS. 1 and 2, the right panel 120, the left panel 130, and the front panel 150 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. It is provided with a metal frame portion 320 that extends continuously to the end. The front panel 150 also includes a metal 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 170 includes metal frame portions 320 that extend continuously 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 100 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 310. 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 FIG. 1 and FIG. 2, by disposing the metal frame portion 320 on the outer panel, the metal frame portion 320 does not contact the heat insulating space 300, so that it is possible to suppress a decrease in the heat insulating performance of the heat insulating container.

  The heat insulation container 100 of this 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 heat insulation containers stacked in two stages by providing the metal support portion 310. It can control that a heat insulating material is damaged. Moreover, the heat insulation container 100 of this example forms the heat insulation space 300 by the panel surface of the inner side panel which has a vacuum heat insulating material, and prevents the metal support part 310 from contacting the heat insulation space 300, thereby insulating the heat insulation container. It can suppress that performance falls from the metal support part 310. FIG.

  As shown in FIG. 3, the heat insulation container 100 of this example can be stored and transported with the heat insulation containers 100A 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 500 is placed on the floor of the work place with the surface on which the load is placed facing up. The bottom panel 190 of the heat insulating container 100 is disposed on the surface of the pallet 500 on which a load can be placed. Place the load on the bottom panel. The thermal insulation container 100 in the disassembled state is assembled so that the luggage is stored inside the container. Thereby, the heat insulation container 100 of the assembly state in which the load loaded on the pallet 500 was accommodated inside can be obtained. It should be noted that the assembly work of the disassembled heat insulation container 100 may be started before the luggage is deposited on the bottom panel, and the luggage may be stored in the container after the assembly or / and during the assembly. With the same procedure, the insulated container 100A in an assembled state in which the luggage placed on the pallet 502 is housed can be obtained. Then, the heat insulating container 100A is loaded on the heat insulating container 100 using, for example, a forklift.

  Hereinafter, the heat insulation container of the present disclosure will be described in more detail with some embodiments.

2. First Embodiment (a) Structure of Thermal Insulation Container A first embodiment will be described. FIG. 4 is a diagram illustrating the heat insulating container 100 according to the first embodiment. FIG. 5 is a diagram for explaining each component member of the heat insulating container 100.

  The heat insulating container 100 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 100 has a substantially rectangular parallelepiped shape and includes a pallet 500 for conveyance. A claw hole 501 penetrating the opposite side surface is provided on the side surface of the pallet 500. By inserting the claw portion of the forklift into the claw hole 501, the heat insulating container 100 in which the article is stored can be moved together with the pallet 500.

  As shown in FIG. 4, the heat insulating container 100 has a substantially rectangular parallelepiped shape surrounded by the pallet 500, the bottom panel 190, the front panel 150, the left panel 130, the back panel 140, the right panel 120, and the top panel 170. The front panel 150 faces the back panel 140 in a state where the panel surface is parallel, and is adjacent to the top panel 170, the bottom panel 190, the left panel 130, and the right panel 120 in a vertical positional relationship. The left panel 130 faces the right panel 120 in a state where the panel surface is parallel, and is adjacent to the top panel 170, the bottom panel 190, the back panel 140, and the front panel 150 in a vertical positional relationship. . The back panel 140 is adjacent to the top panel 170, the bottom panel 190, the right panel 120, and the left panel 130 in a vertical positional relationship.

  The outer peripheral shape of the outer panel surface of the side panel 110 of the heat insulating container 100 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 100 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 of a single 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 500 used together. The heat insulating container 100 of the present 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 150 is a panel that can be partially opened and closed by a hinge 101. Metal support portions 310 extending in the direction parallel to the Z direction are disposed at the ends of the front panel 150 in the + Y direction and the −Y direction. Frame portions 320 extending in the direction parallel to the Y direction are arranged at the end portions of the front panel 150 in the + Z direction and the −Z direction.

As shown in FIG. 5, the top panel 170 includes an outer panel 170B and an inner panel 170A. Front panel 150, left panel 130, rear panel 140, and right panel 120 have outer panels 150B, 130B, 140B, and 120B, and inner panels 150A, 130A, 140A, and 120A, respectively. The bottom panel 190 is constituted only by the inner panel 190A. 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 300.

(B) Assembly and disassembly of heat insulation container (i) Assembly of heat insulation box FIGS. 6-10 is a figure explaining an example of each assembly process at the time of assembling the heat insulation container 100 in order. First, as shown in FIG. 6, the bottom panel 190 is laid on the pallet 500. Next, the left panel 130 is placed upright on the −Y direction side of the bottom panel 190. The inner panel 130A of the left panel 130 is disposed on the + Y direction side that is the heat insulation space 300 side.

  Next, as shown in FIG. 7, the back panel 140 is arranged upright on the −X direction side of the bottom panel 190. The inner panel 140A of the back panel 140 is disposed on the + X direction side, which is the heat insulation space 300 side.

  Next, as shown in FIG. 8, the right panel 120 is placed upright on the + Y direction side of the bottom panel 190. The inner panel 120A of the right panel 120 is disposed on the −Y direction side, which is the heat insulation space 300 side.

  Next, as shown in FIG. 9, the front panel 150 is placed upright on the + X direction side of the bottom panel 190. Side panel guides 352 toward the pallet 500 are provided at the lower end portions of the left panel 130, the back panel 140, the right panel 120, and the front panel 150. Adjacent to the sides. Thereby, even if the side panel 110 receives a horizontal force from the outside, the panel is prevented from being displaced and sliding off the pallet 500. The inner panel 150 </ b> A of the front panel 150 is disposed on the −X direction side that is the heat insulation space 300 side.

  Finally, as shown in FIG. 10, the top panel 170 is placed above the four side panels 110, that is, on the + Z direction side, and the assembly of the heat insulating container 100 is completed. Although the top panel 170 only covers the four side panels 110 under its own weight, the top panel guide part 351 facing the side panel side is attached to the end portion, so even if it receives vibration 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 110 may be additionally performed, or may be joined using a hook-and-loop fastener or the like.

  In the above description of the assembling method, the side panel 110 is assembled in the order of the left panel 130, the rear panel 140, the right panel 120, and the front panel 150. The right panel 120, the back panel 140, the left panel 130, and the front panel 150 can be assembled in this order, and the front panel 150, the left panel 130, the back panel 140, and the right panel 120 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 170 is removed, then the front panel 150 is removed as the reverse work of FIG. 9, and then the right panel 120 is removed as the reverse work of FIG. . Further, as the reverse operation of FIG. 7, the rear panel 140 is removed, and finally, the reverse operation of FIG. 6 is performed to remove the left panel 130 and the bottom panel 190, thereby completing the disassembly operation.

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

  Fig.11 (a)-FIG.11 (c) are the figures which looked at the state which piled up each decomposed | disassembled panel in the designated order from the side surface.

  As shown in FIG. 11A, in a state where the heat insulating container 100 is disassembled, for example, a bottom panel 190 constituted by an inner panel 190A is placed, and a left panel 130 is disposed on the bottom panel 190 and an inner panel 130A is disposed on the lower side. The upper side is overlaid in the direction to become the outer panel 130B, and the back panel 140 is overlaid on the upper side in the direction to become the outer panel 140B on the upper side and the inner panel 140A on the upper side. The right panel 120 is overlaid thereon so that the lower side is the inner panel 120A and the upper side is the outer panel 120B. Further, the front panel 150 is further on the lower side, the outer panel 150B, and the upper side is the inner panel. The top panel 170 is overlaid in the direction of the inner panel 170A on the lower side and the outer panel 170B 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.

  As shown in FIG. 11B, it is also effective to provide an order identification display 105 that can clearly identify whether or not the panel stacking order is correct by looking at the side of the stacked panels. It can be managed so that the order in which the disassembled panels are stacked does not change depending on the level of proficiency of the operator and the presence or absence of misunderstanding. In FIG. 11 (b), a display is made so that a continuous parallelogram shape can be recognized when they are overlapped. However, the present invention is not limited to this. It is also possible that the correct design can be recognized when correctly stacked, but the design is attached so that the correct design cannot be recognized when stacked incorrectly.

  As shown in FIG. 11C, the fitting structure for identifying the order in which the fitting protrusion 106a and the fitting recess 106b are correctly fitted only when the outer panels to be overlapped with each other are correctly stacked. 106 may be provided. In addition, FIG.11 (c) is the figure which expanded the A section of Fig.11 (a). For example, different positions and sizes are provided on the adjacent surfaces of the outer panel 130B of the left panel 130 and the outer panel 140B of the rear panel 140, the outer panel 120B of the right panel 120, and the outer panel 150B of the front panel 150, respectively. If the order-identifying fitting structure 106 is provided in quantity, even if the panels are stacked in the wrong order and combination, places that cannot be fitted will appear, so the operator can easily recognize the mistake. it can.

(C) Side panel (i) structure The side panel 110 is demonstrated among each panel which comprises the heat insulation container 100. FIG. The side panel 110 includes a front panel 150, a left panel 130, a rear panel 140, and a right panel 120, which are four panels, and the left panel 130, the rear panel 140, and the right panel 120 have the same structure. Therefore, the configurations of the back panel 140 and the front panel 150 will be sequentially described. FIGS. 12A and 12B are views of the rear panel 140 viewed from the direction perpendicular to the panel surface. FIG. 12A is a view of the back panel 140 viewed from the −X direction side, which is the outside of the heat insulating container 100, and FIG. 12B is a view of the back panel 140 viewed from the + X direction side, which is the inside of the heat insulating container. FIG.

(Ii) Structure of the back panel (1) As shown in FIG. 12A, when the back panel 140 is viewed from the outside of the heat insulating container 100, the outside panel 140B is visually recognized. The outer panel 140B has two metal support portions 310 and two frame portions 320 arranged in a frame shape along the edge of the outer panel 140B so as to surround the protective material 322 and the periphery of the protective material 322. It is composed of Further, as shown in FIG. 12B, the rear panel 140 has the inner panel 140A visually recognized when viewed from the inside of the heat insulating container 100, and the end of the outer panel 140B is located outside the outer periphery of the inner panel 140A. A part of the two metal support parts 310 and the two frame parts 320 arranged in the part are visually recognized. The inner panel 140A is mainly composed of a heat insulating portion 330 including a vacuum heat insulating material 331 described later.

  Each dimension of the outer periphery of the inner panel 140A is smaller than each dimension of the outer periphery of the outer panel 140B, and the inner panel 140A is disposed within the panel surface of the outer panel 140B. 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 140A 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.

(2) Inner panel The structure of the inner panel 140A will be described. FIG. 13A and FIG. 13B are cross-sectional views of the heat insulating portion 330. FIG. 14A and FIG. 14B are cross-sectional views of the vacuum heat insulating material 331 included in the heat insulating portion 330.

  FIG. 13A is a cross-sectional view showing an example of the structure of the heat insulating portion 330. The heat insulating part 330 includes a vacuum heat insulating material 331, a foam heat insulating material 332 that surrounds both one and end surfaces of the vacuum heat insulating material 331, and a heat insulating sheet 333 that encloses the entire outer periphery thereof. Since the foam heat insulating material 332 is disposed on both sides of the end surface of the vacuum heat insulating material 331, the heat insulating performance is compared to the case where the foam heat insulating material 332 is not disposed on both sides of the end surface of the vacuum heat insulating material 331 and is a space. Will improve. The vacuum heat insulating material 331 includes a core material 331a and an exterior material 331b. Since the vacuum heat insulating material 331 cannot maintain a vacuum when the exterior material 331b is damaged and cannot obtain a desired heat insulating property, the vacuum heat insulating material 331 has a foam heat insulating material 332 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 331 will be damaged can be reduced. In addition, in the structure of Fig.13 (a), the vacuum heat insulating material 331 is protected by the outer side panel arrange | positioned on the opposite side to a 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 331.

  When forming the heat insulating portion 330 shown in FIG. 13 (a), it is not always necessary to set the vacuum heat insulating material 331 in the mold and then integrally form the foam heat insulating material 332 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 placing the vacuum heat insulating material 331 and the foam heat insulating material 332, and maintenance is also improved, for example, it is easy to replace only the vacuum heat insulating material. The vacuum heat insulating material 331 and the foam heat insulating material 332 may be fixed using an adhesive. When fitting without using an adhesive, the vacuum heat insulating material 331 can be configured to be removable from the foam heat insulating material 332. The vacuum heat insulating material 331 can also be configured to be removable from the foam heat insulating material 332 by using a weak adhesive.

  FIG. 13B is a cross-sectional view illustrating another example of the structure of the heat insulating portion 330. The heat insulating part 330 includes a vacuum heat insulating material 331, a foam heat insulating material 332 that surrounds the vacuum heat insulating material 331, and a heat insulating sheet 333 that surrounds the foam heat insulating material 332. The sheet 333 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 330 includes a vacuum heat insulating material 331, a foam heat insulating material 332 surrounding the vacuum heat insulating material 331, a protective base material surrounding the foam heat insulating material 332, and a heat shield sheet 333 surrounding the protective base material. It may be configured. 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 331 includes a core material 331a and an exterior material 331b having gas barrier properties, and is a heat insulating material obtained by reducing the pressure inside the exterior material 331b. FIG. 14B is another example of the vacuum heat insulating material 331. In FIG. 14A, gaps are formed at both ends inside the vacuum heat insulating material 331, but 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 331.

  As the core material 331a, 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, and the like The porous body may be used.

  The exterior material 331b is a member that covers the outer periphery of the core material 331a, 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.

For example, providing the area | region where the foam heat insulating material 332, the heat insulation sheet 333, and the protection base material 338 do not exist, or making some or all of them transparent is mentioned. When the vacuum heat insulating material 331 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 breaking the inner panel.

(3) Outer panel The structure of the outer panel 140B will be described. As shown in FIG. 12A, the outer panel 140B is arranged outside the inner panel 140A and arranged in a frame shape along the end face of the outer panel 140B so as to surround the protective material 322 and the periphery of the protective material 322. And two metal support portions 310 parallel to the Z direction and two frame portions 320 parallel to the Y direction.

  The structure of the adjacent part of the back panel 140 and the left panel 130 will be described. FIG. 15A and FIG. 15B are a plan view and a cross-sectional view of an adjacent portion between the back panel 140 and the left panel 130. FIG. 15A is a plan view of the heat insulating container 100 viewed from the + Z direction when the top panel 170 is removed. FIG. 15B is an enlarged view of a portion near the portion B in FIG. 15A cut by a cross section perpendicular to the Z direction at the position of the screw coupling portion 341 that couples the adjacent portion of the rear panel 140 and the left panel 130. It is sectional drawing.

  As shown in FIG. 15A, the side panel 110 is disposed so that the end surface of the inner panel 150 </ b> A of the front panel 150 and the panel surface of the inner panel 130 </ b> A of the left panel 130 come into contact with each other. Are arranged so that the end surface of the inner panel 140A of the rear panel 140 abuts with the panel surface of the inner panel 140A of the rear panel 140 and the end surface of the inner panel 140A of the rear panel 140 and the panel surface of the inner panel 120A of the right panel 120. The end surface of the inner panel of the right panel 120 and the panel surface of the inner panel 150A of the front panel 150 are disposed so as to contact each other. As described above, each side panel 110 has its inner panel in contact with two adjacent side panels at two positions of the end surface and the panel surface. Thereby, when each panel of the side panel 110 is not provided with an opening / closing part, all 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 130, the back panel 140, and the right panel 120 are misplaced, they can be assembled without any problems, and there are no functional problems, improving workability and convenience. it can. Note that the arrangement of each panel is not limited to that shown in FIG.

  The metal support part 310 is demonstrated. As shown in FIG. 15B, as the configuration of the left panel 130, there is a heat insulating portion 330 including a heat insulating sheet 333, a foam heat insulating material 332, and a vacuum heat insulating material 331 from the + Y direction side to the −Y direction side. is there. On the −Y direction side, there is a protective material 322 with an adhesive 334 interposed therebetween, and the adhesive 334 adheres and fixes the heat insulating portion 330 and the protective material 322. A partial support portion 310a, which is a constituent member of the metal support portion 310, is fitted and fixed to the tip of the protective material 322 in the −X direction with a groove portion 310c interposed therebetween. The protective material 322 and the partial support part 310a are constituent members of the outer panel 130B. Further, as a configuration of the adjacent back panel 140, there is a heat insulating portion 330 including a heat insulating sheet 333, a foam heat insulating material 332, and a vacuum heat insulating material 331 from the + X direction side toward the −X direction side. The protective material 322 is sandwiched between the adhesive 334 on the −X direction side, and the adhesive 334 adheres and fixes the heat insulating portion 330 and the protective material 322. The internal structure of the heat insulating portion 330 of the back panel 140 is the same as the heat insulating portion 330 of the left panel 130 described above. A partial support portion 310b, which is a constituent member of the metal support portion 310, is fitted and fixed to the front end of the protective material 322 in the -Y direction with a groove portion 310c interposed therebetween. The partial support portion 310b and the above-described partial support portion 310a are connected to each other by a screw coupling portion 341 having a through hole formed in a part thereof.

  In FIG. 15B, an end surface 330a of the heat insulating portion 330 that is an end surface on the −X direction side of the inner panel 130A of the left panel 130 is a surface of the heat insulating portion 330 that is an inner panel surface of the inner panel 140A of the back panel 140. 330b, and the heat insulating property of the heat insulating space surrounded by the heat insulating portion 330 is maintained. Further, the partial support part 310 a of the left panel 130 and the rear panel 140 partial support part 310 b abut to form an integral metal support part 310, which is perpendicular to the panel surface of the bottom panel 190. In such a direction, it continuously extends from the end on the top panel 170 side to the end on the bottom panel 190 side to the end on the top panel 170 side. Since the two partial support portions 310a and 310b are connected by the screw coupling portion 341, the left panel 130 and the rear panel 140 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 310 supports the load applied in the vertical direction, whereby the risk of deformation or breakage of the vacuum heat insulating material can be reduced. For the metal support portion 310, all metal materials 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.

Plastic cardboard or cured wood can be used as a lightweight and relatively rigid material. The protective material 322 is bonded to the heat insulating portion 330 adjacent to the inner side, that is, the heat insulating space side, through the adhesive 334. As the adhesive 334, 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 detachable, for example, when it is desired to replace only the vacuum heat insulating material 331, it is not necessary to remove the entire panel from the heat insulating container 100, and the maintainability is improved.

  The frame unit 320 will be described. As described with reference to FIGS. 12A and 12B, the frame portion 320 is provided on the upper and lower ends of the outer panel from the right end of the outer panel to the left end of the outer panel, respectively.

In the present embodiment, the material of the frame part 320 is designed and simplified by using the same member as that of the metal support part 310. 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 panel 140 </ b> B of the rear panel 140 can include a side guide portion 352 that is a protruding portion toward the pallet 500 so that the later-described rear panel 140 does not slide off the pallet 500.

In order to prevent sudden battery exhaustion during use, it is preferable that the power supply unit includes a secondary battery that can generate power or generate power from communication radio waves.

  In addition, the sensor unit 630 is electrically connected to the RF tag unit 610 via the cable unit 620, and receives an electric power supply from the power supply unit 615 of the RF tag unit 610, and changes the surrounding environmental state according to an instruction from the RF tag unit 610. The measurement result is output to the RF tag unit 610. The environmental condition of the measurement target is, for example, temperature, humidity, pressure, acceleration, position, and the like. A known temperature sensor, humidity sensor, pressure sensor, acceleration sensor or vibration sensor, GPS sensor, or the like can be used.

  Details of the operation and function of the sensor-equipped RF tag 600 will be described. First, by non-contact communication between the external device and the sensor-equipped RF tag 600, instruction information about the measurement frequency at which the sensor unit 630 measures the environmental state of the heat insulation space is transmitted from the external device to the sensor-equipped RF tag 600. The sensor unit 630 is assumed to be a temperature sensor.

  The RF tag unit 610 of the sensor-equipped RF tag 600 obtains instruction information from an external device through the communication antenna unit 611 and the communication interface unit 612, decodes it by the control unit 613, and at predetermined time intervals according to the measurement frequency information. Then, a measurement instruction is transmitted to the sensor unit 630. The sensor unit 630 performs temperature measurement according to a measurement instruction from the control unit 613 transmitted from the wired interface unit 616 via the cable unit 620 while receiving power supply from the power source unit 615 through the cable unit 620, and obtains measurement data. It transmits to the control part 613.

  The control unit 613 of the RF tag unit 610 receives the temperature measurement data transmitted from the sensor unit 630 instructed to measure every predetermined time, and stores the temperature measurement data in the storage unit 614. The storage unit is preferably a nonvolatile memory. When this is repeated and an instruction to output the temperature measurement data measured by the sensor unit 630 is received from an external device, the RF tag unit 610 reads the temperature measurement data stored in the storage unit 614 and externally communicates via non-contact communication. Output to the device. Accordingly, the external device issues an instruction by wireless communication to the RF tag 600 with a sensor attached to the heat insulating container 100 at an arbitrary timing, so that the sensor unit 630 is in accordance with the measurement time interval designated in advance. It becomes possible to read out the measured temperature value of the insulated space.

  By the way, if the sensor unit 630 and the RF tag unit 610 are brought close to each other and installed inside the inner panel 130A, the length of the cable unit 620 can be shortened, and the trouble of providing a through hole in the outer panel can be saved. However, for the heat shield sheet 333 covering the outer periphery of the heat insulating portion 330 of the inner panel 130A and the exterior material 331b of the vacuum heat insulating material 331, a vapor deposition sheet or the like in which a vapor deposition layer is formed on one side of a metal foil or a resin sheet is used. Since there are many metal members, there is a possibility that the wireless communication function between the RF tag unit 610 and the external device may be hindered, and there is a fear that the communication distance and communication stability may be reduced.

  For this reason, as in this embodiment, the RF tag unit 610 is separated from the sensor unit 630, and is attached to the outside of the outer panel 130B and in a place avoiding the metal part such as the metal support unit 310. The wireless communication with the communication device is not hindered, and a good communication distance and communication stability can be obtained.

  Also, as shown in FIGS. 22 (a) and 22 (b), the cable portion 620 is not routed to the end of the inner panel 130A, but a through hole 330c is formed in the panel surface of the inner panel 130A and pulled out to the outside of the inner panel. You can also. However, in this case, it is necessary to select a location and a hole diameter of the through hole so as to avoid disposing the vacuum heat insulating material 331 in the heat insulating portion 330. Further, in this figure, the RF tag portion 610 is disposed not in the outside of the outer panel 130B but in a gap portion with the inner panel 130A inside. By doing so, it is not easy to attach and detach the RF tag unit 610 from the heat insulating container 100, but the risk of damage to the RF tag unit 610 due to external force during storage or transportation can be reduced.

  As described above, FIG. 21 and FIG. 22 have described the form in which the RF tag portion 610 and the sensor portion 630 of the RF tag 600 with a sensor are attached to the left panel 130. However, the RF tag 600 with a sensor is not limited to this. It may be attached to the panel, or may be attached to a plurality of panels. Furthermore, a plurality of types of RF tags with sensors 600 themselves may be attached for measuring different environmental conditions. For example, for the same heat insulating container 100, a plurality of sensor-equipped RF tags 600 each having a temperature sensor, a humidity sensor, an acceleration sensor, and a position sensor may be attached to a plurality of panels.

  In addition, the small electronic device including the sensor-equipped RF tag 600 may be all or part of the small electronic device attached to the pallet 500, and may be disposed on the top surface, the bottom surface, the side surface, and any location inside the pallet 500. . For example, you may arrange | position near the center part of the horizontal direction side of the side surface of the pallet 500, Furthermore, you may arrange | position near the center part of each horizontal direction of 2 adjacent side surfaces. Alternatively, a pallet on which all or a part of the small electronic device including the sensor-equipped RF tag 600 is attached and a pallet that is not so may be selectively used, and a pallet may be selected according to necessity.

  Further, depending on the use of the heat insulating container 100 and the required content, the side panel in which the RF tag portion 610 of the RF tag with sensor 600 is used and the case where the side panel is not used are replaced with a spare panel. Depending on the operation, it may be used properly. For example, the left panel 130 has two panels, one having the RF tag portion 610 of the sensor-equipped RF tag 600 and one not disposed, and wireless communication of the sensor-equipped RF tag 600 is required. In this case, the heat insulating container 100 is assembled using the left panel 130 on which the RF tag unit 610 is disposed, and the left panel 130 on which the RF tag unit 610 is not disposed can be stored as a spare panel. . Conversely, when wireless communication of the sensor-attached RF tag 600 is not required, the heat insulating container 100 is assembled using the left panel 130 on which the RF tag unit 610 is not disposed, and the left panel on which the RF tag unit 610 is disposed. 130 may be stored as a spare panel. This can be applied to the top panel 170 and the bottom panel 190 as well as the left panel 130 and other side panels 110.

    As described above, the heat insulating container 100 attached with the sensor-equipped RF tag 600 can measure a desired environmental state such as the temperature of the heat insulating space, and can read the measurement data from an external device by wireless communication as necessary. It is. As a result, it is possible to grasp the environmental status including the temperature history of the heat insulation space, that is, the temperature history of the article, and it is possible to easily acquire important information for guaranteeing the article without opening the heat insulation container.

  In addition, by attaching the RF tag part 610 to a position outside the outer panel 130B and avoiding the metal support part 310, it is possible to suppress deterioration of the communication function due to the metal member existing in a wide area near the inner panel 130A, and to be good Communication distance and communication stability can be obtained.

(J) Conductive Material A mode in which a conductive sheet 701 for reducing accumulation of static electricity is attached to the heat insulating container 100 will be described. FIG. 24A, FIG. 24B, and FIG. 25 are views showing a state in which a conductive sheet 701 is attached to the heat insulating container 100 of the present embodiment. FIG. 24A is an explanatory view of a heat insulating container provided with a conductive sheet 701 on the inner panel surface of the bottom panel 190 of the heat insulating container 100, and the front panel 150 and the top panel 170 are omitted. . FIG. 24B is an enlarged cross-sectional view of FIG. 24A taken along the cross section perpendicular to the Z direction at the position of the inner panel surface of the bottom panel 190 as viewed from the + Z direction.

  24A and 24B, the heat insulating container 100 includes a conductive sheet 701 having conductivity on the upper panel surface of the bottom panel 190, and further, a ground connection portion 731 outside the heat insulating container 100. The two are electrically connected by a cable portion 720. The cable portion 720 is disposed on the inner panel surface of the bottom panel 190, and is pulled out through the through hole 322c of the protective member 322 of the outer panel 130B through the gap between the left panel 130 and the rear panel 140. And connected to the ground connection portion 731.

  The conductive sheet 701 is not particularly limited as long as it is a highly conductive member. For example, a vapor deposition layer in which a vapor deposition layer is formed on one side of a metal sheet such as stainless steel, copper, or aluminum, or a multilayer sheet or metal sheet containing a metal foil. A sheet etc. may be sufficient and a nonmetallic highly conductive member like a graphite sheet may be sufficient. In addition, as a electrically conductive material which can be used by this embodiment, it is not limited to a sheet-like electroconductive sheet, For example, a linear or block-shaped thing may be sufficient.

  24A and 24B, when an article is put in the heat insulating container 100, the article is electrically connected to the conductive sheet 701 laid on the top of the bottom panel 190, and the cable portion electrically connected thereto. It is electrically connected to the ground connection portion 731 outside the heat insulating container 100 through 720. For this reason, if the ground connection portion 731 is electrically connected in advance to a storage location or a ground location of transport equipment, that is, a site where grounding can be taken, the static electricity on the article or the insulated container 100 itself can be safely released to the outside. . Therefore, even when a combustible article is stored or when there is a combustible substance in the vicinity of the heat insulating container 100, it is possible to reduce the risk of a fire accident due to electrostatic discharge or the like. The ground connection portion 731 may be a metal piece or a conductive member, and may have a shape that can be fixed by being sandwiched between external groundable places like a clip.

  FIG. 25 is a diagram illustrating a state in which a conductive sheet is attached to the entire surface covering the heat insulating space of the heat insulating container 100. As shown in this figure, not only on the inner panel surface of the inner panel 190A of the bottom panel 190, but also on the inner panel surface of the inner panel 110A of the side panel 110 and the inner panel surface of the inner panel 170A of the top panel 170. In addition, a conductive sheet 701 is attached, and a conductive mat 732 is laid on the lower surface of the pallet 500, and both are electrically connected by a cable portion 720. In FIG. 25, the front panel 150 and the top panel 170 are omitted, but actually, the conductive sheet 701 also exists in these panels.

  As shown in FIG. 25, by sticking the conductive sheet 701 to a wide area covering the heat insulation space, it is possible to enhance the effect of safely releasing the static electricity on the article or the heat insulation container 100 itself to the outside. Further, a conductive mat 732 is laid on the lower surface of the pallet 500 and integrated with the pallet 500, so that even if the grounding is forgotten, the conductive mat 732 laid on the lower surface of the pallet 500 is removed. Discharge effect to the outside and the atmosphere in contact with nature can be expected. That is, there is an effect of reducing the risk of an ignition accident due to electrostatic discharge when the stored article is flammable or there is a flammable substance in the vicinity of the heat insulating container 100. As the conductive mat 732, a hydrophilic polymer material is mixed with a material in which a metal such as aluminum, gold, or zinc is vapor-deposited on the surface, acrylonitrile / butadiene / styrene (ABS), polystyrene, acrylic resin, or the like. Various types can be used such as a polymer alloy type and a mixture of carbon black and polymer material.

3. Second Embodiment (a) Structure of Thermal Insulation Container A second embodiment will be described. FIG. 26 is a diagram illustrating a heat insulating container 100B according to the second embodiment of the present invention. FIG. 27 is a diagram illustrating a state in which all doors are open in the heat insulating container 100B according to the second embodiment. 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 are that the top panel 170 can be folded, and the front panel 150 in the closed state of the front door 161 in the cross section orthogonal to the rotation center axis m of the front panel 150. 151 and the front door 161 are not on the same plane.

(B) Modification of Top Panel As shown in FIG. 26, the top panel 170 is divided into two on a straight line n parallel to the Y direction, and has a first upper plate portion 171 and a second upper plate portion 181. ing. The first upper plate portion 171 and the second upper plate portion 181 are fixed so as to be rotatable around the straight n axis via a hinge 102 disposed on the straight line n.

  As shown in FIG. 27, with the first upper plate portion 171 held by the side panel 110, the second upper plate portion 181 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 171 can be opened and closed while the second upper plate portion 181 is held on the side panel 110. Even after the heat insulation container 100 is assembled, the second upper plate portion 181 or the first upper plate portion 171 can be opened to put in and out the article. For example, when luggage is loaded in front of the front panel 150 and it is difficult to open the front panel 150, the luggage can be taken in and out from the top side.

  Furthermore, when disassembling the heat insulating container 100B, the top panel can be removed from the side panel after the top panel is folded as shown in FIG. Further, when assembling the heat insulating container 100B, 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. 26, the front panel 150 is divided into two on a straight line m parallel to the Y direction, and a front plate portion 151 that is a fixed portion that does not open and close on the −Z direction side. And a front door 161 on the + Z direction side that can be opened and closed by rotating to the + X direction side with respect to the front plate portion 151 around the axis of the straight line m. doing. The front door portion 161 is attached to the front plate portion 151 via a hinge 101 arranged on a straight line m. The front door portion 161 opens and closes around the straight m axis with respect to the front plate portion 151. It is fixed so that it can rotate freely.

  Since the front panel 150 includes the front plate portion 151 and the front door portion 161, the front door portion 161 can be opened and articles can be taken in and out even after the heat insulating container 100B is assembled. Even when other heat insulating containers are stacked on the upper stage of the heat insulating container 100B, the front door portion 161 allows the articles to be taken in and out.

  The configuration of the front panel 150 will be described. FIG. 28 is a view of the front panel 150 as viewed from the inside. When the front panel 150 is viewed from the inside, the inner panel 161A is visually recognized on the + Z direction side, and the inner panel 151A is visually recognized on the −Z direction side. The metal support part 310 and the frame part 320 which are arrange | positioned at the edge part of the outer side panels 161B and 151B which are not illustrated on the outer side of the outer periphery of the inner side panels 161A and 151A are visually recognized.

  The arrangement of the inner panels 151 </ b> A and 161 </ b> A in the Z direction is such that the boundary surface between the inner panels 151 </ b> A and 161 </ b> A is shifted in the + Z direction from the straight line m that is the rotation center axis of the front door portion 161. Thus, in a state where the front door portion 161 is opened, a plurality of stepped steps are generated at the end portions in the vicinity of the adjacent portions of the front plate portion 151 and the front door portion 161.

  FIG. 29 is a cross-sectional view taken along the line EE shown in FIG. The front plate portion 151 is joined to the heat insulating portion 330 and the heat insulating portion 330 including the heat insulating sheet 333, the foam heat insulating material 332, and the vacuum heat insulating material 331 through the adhesive 334 in order as viewed from the −X direction. A front plate portion opening / closing frame portion 321a and a protective member 322 which is a constituent member of the outer panel 151B fitted to the front plate portion opening / closing frame portion 321a with a groove portion 321c therebetween are disposed. Moreover, the front door part 161 also has the same structure, and the heat insulation part 330 comprised from the heat insulation sheet 333, the foam heat insulating material 332, and the vacuum heat insulating material 331 in order seeing the front door from the -X direction, the heat insulating part. The front door part opening / closing frame part 321b joined to the front door part opening / closing frame part 321b with the groove part 321c interposed therebetween is disposed. Has been. The front plate part opening / closing frame part 321a and the front door part opening / closing frame part 321b are rotatably fixed by a hinge 101.

  As shown in FIG. 29, a boundary surface between the front panel opening / closing frame portion 321a and the front door opening / closing frame portion 321b, which is a boundary surface between the outer panel 151B of the front plate portion 151 and the outer panel 161B of the front door portion 161 viewed in a cross section. And the boundary surface of each heat insulating portion 330, which is the boundary surface between the inner panel 151A of the front plate portion 151 and the inner panel 161A of the front door portion 161, are formed at different positions in the Z direction. The boundary surface of 151 and the front door part 161 is not on the same plane. Thereby, in the state which closed the front door part 161, inflow of the air from the outside will be prevented and there exists an effect which maintains the heat insulation of heat insulation space. Further, the respective heat insulating portions that are the vicinity of the boundary surface between the front plate portion opening / closing frame portion 321a and the front door portion opening / closing frame portion 321b, and the boundary surface between the inner panel 151A of the front plate portion 151 and the inner panel 161A of the front door portion 161. The vicinity of the boundary surface of 330 is a portion where the heat insulating performance is lower than that of other portions, so that the heat insulating property reduction region near the boundary surface of the front plate portion opening / closing frame portion 321a and the front door portion opening / closing frame portion 321b. In addition, by disposing the heat insulating portion 330 including the vacuum heat insulating material 331, there is also an effect of suppressing a heat bridge caused by overlapping heat insulating performance degradation regions.

  FIG. 30 is a view showing a state where the front door portion 161 is opened in a cross section similar to FIG. FIG. 31 is a perspective view showing a state in which the front door portion 161 is opened based on the cross section of FIG. As shown in these figures, in the state where the front door portion 161 is open, the end portions near the front plate portion 151 and the adjacent portion of the front door portion 161 are stepped in order from the −X direction to the + X direction. The warning tape 103 is affixed to the stepped end portion. The material and design of the warning tape 103 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 103 alerts the fingers to prevent pinching, and the article hits the inner panel 161A protruding upward from the outer panel 161B of the front door 161 during the loading / unloading operation of the article. The purpose of this is to call attention to prevent the vacuum heat insulating material of the inner panel 161A from being damaged. Further, in the present embodiment, the place where the warning tape 103 is affixed is the back side when the front door portion 161 is opened from the front panel 150 in the X direction, that is, when the heat insulating container 100A is viewed from the side where the articles are put in and out. That is, the visibility of the warning tape 103 is remarkably improved because it is a step having a structure in which the step rises as it goes to the −X direction side.

  Further, in the present embodiment, as a safety measure when opening the front door portion 161, each of the positions outside the front plate portion 151 and the front door portion 161 and facing each other when the front door portion 161 is opened, As shown in FIG. 26, a buffer material 104 is provided. Even if an operator pinches a finger when closing the front door part 161, damage can be reduced.

  In the present embodiment, the boundary surface portion between the first upper plate portion 171 and the second upper plate portion 181 will not be described, but the same configuration as the boundary surface portion between the front plate portion 151 and the front door portion 161 may be adopted. Good.

4). Third Embodiment (a) Structure of Thermal Insulation Container A third embodiment will be described. FIG. 32 is a diagram illustrating a heat insulating container 100C according to the third embodiment of the present invention. The main difference from the second embodiment is that the heat insulating container 100C holds the front door 161 in a closed state, releases the locked state by operating the operation member 202, and opens the front door 161 in the + X direction. It has a latch mechanism that can. Furthermore, in order to protect the vacuum heat insulating material and the operation member 202 and improve the operability, the deformable handle portion 205 or the handle portion 215 that covers at least a part of the operation member 202 is attached. The risk that the operating member 202 accidentally collides with the vacuum heat insulating material and damages the vacuum heat insulating property can be reduced. Further, since the operation member 202 is provided so as to protrude in the + X direction side, various objects may collide during the work. In order to reduce this risk, it is necessary to make the operation member 202 small so as to have a minimum protrusion amount that can be operated, but the front door portion is operated while operating the operation member 202 against the force of the spring. Since a plurality of operations of lowering 161 to the front are performed at the same time, workability is reduced. By attaching the handle portion 205 or the handle portion 215, it is possible to prevent damage to the operating member and improve workability.

(B) Latch mechanism with handle portion FIGS. 33 and 34 are views showing the vicinity of the operation member 202 for operating the latch mechanism with handle portion. FIG. 35 is a view of the vicinity of the operation member 202 for operating the latch mechanism with the handle portion as viewed from above. FIG. 36 is a view of the vicinity of the operation member 202 for operating the latch mechanism with the handle portion as seen from the front side.

As shown in FIGS. 33, 34, 35, and 36, the handle portion 205 is disposed on the front door portion 161 so as to cover the entire operation member 202 when viewed from the + X direction side, that is, the front side from the front panel 150. Has been. Note that the handle portion 205 is provided at a position corresponding to each of the two operation members 202. In this embodiment, the handle portion 205 is made of a flexible belt-like leather, but may be a hard material having a link portion or the like as described later as long as it can be deformed. Moreover, the fixing method to the front door part 161 can also be suitably selected from screwing, riveting, an adhesive, or the like.

  The handle portion 205 normally has a central portion at a position (first position) shown in FIGS. 35 and 36 that can be grasped by an operator when the front door portion 161 is opened and closed. FIG. 37 is a diagram illustrating a state in which the central portion of the handle portion 205 is in a second position that is closer to the operation member 202 than the first position. For example, when an external force such as an impact is applied to the vicinity of the operation member 202 of the heat insulating container 100C from the outside, the handle portion 205 is deformed so that the center portion of the handle portion 205 is located at a position higher than the first position as shown in FIG. It is possible to move to the second position close to the operation member 202. Accordingly, it is possible to avoid the external force from being concentrated on the operation member 202 while the handle portion 205 is deformed, and thus the operation member 202 can be protected.

  The presence of the handle 205 at the normal first position as shown in FIGS. 35 and 36 allows the operator to grip the opening / closing operation of the front door 161, so that the operating member 202 is urged by the spring 203. The operation of pulling down the front door part 161 to the + X direction side can be easily performed while operating against it. Therefore, the operator's operability can be improved.

  FIG. 38 is a view of the handle portion 215 having a link portion having a shape different from that of the handle portion 205 from the upper side. The handle portion 215 includes a grip portion 215a, a first link portion 215b, and a first link portion 215b. 2 link part 215c, and the 1st link part 215b and the 2nd link part 215c are each arrange | positioned one each on the both sides of the holding part 215a. In FIG. 38, the first link portion 215b and the second link portion 215c in the front door portion 161 are also indicated by solid lines for easy viewing. In addition, a state where the grip portion 215a is in the second position is indicated by a broken line.

  The grip portion 215a of the handle portion 215 in such a configuration is a portion that is gripped by an operator during operation, and has a recess 215d for avoiding interference with the operation member 202 when approaching the operation member 202. I have. One end of the first link portion 215b is rotatably attached to the end portion of the grip portion 215a, and the other end is rotatably attached to the end portion of the second link portion 215c. One end of the second link portion 215c is connected to the end portion of the first link portion 215b, and the other end is provided to be movable in the Y direction in the front door portion 161.

  In addition, with such a configuration, the grip portion 215a can move between the first position and the second position as described above. For example, when assembling or disassembling the heat insulating container 100C, When the vacuum heat insulating material of another panel accidentally collides with the operation member 202, the grip portion 215a can move and move to the second position closer to the operation member 202 than the first position. . As a result, the external force is received by the handle portion 215 and the external force is prevented from concentrating directly on the operation member 202, and the vacuum heat insulating material can be protected. Further, the handle portion 215 in the first position can be gripped by the operator when the front door portion 161 is opened and closed, and the front door portion 161 is operated while operating the operation member 202 against the urging force of the spring 203. The operation of pulling down in the + X direction can be easily performed. Since such a handle portion 215 can be formed of a hard resin or metal, the durability of the operation member 202 can be improved.

5. Modifications Various modifications and changes are possible without being limited to the above-described embodiments, and these are also within the scope of the present disclosure. The following are some variations.

(A) Modified Example of Metal Support Part A modified example of the metal support part 310 will be described. In the first embodiment described above, with respect to the structure of the adjacent portion of the left panel 130 and the back panel 140, the partial support part 310a of the left panel 130 and the partial support part 310b of the back panel 140 are screwed as shown in FIG. An integrated metal support 310 is formed by connecting with a joint 341. However, the partial support portion of the metal support portion 310 is not limited to this.

  FIG. 39 shows a cross-sectional shape obtained by cutting adjacent portions of the left panel 130 and the rear panel 140 corresponding to the region B in FIG. 15A with a plane perpendicular to the Z direction. In FIG. 39, the left panel 130 and the back panel are locked by a fitting relationship between a male support 311a having a convex cross section and a female support 311b having a concave shape. The concave female support portion 311b shows a state in which an integral metal support portion 310 is configured. In this case, in the locked state, even if one of the left panel 130 and the rear panel 140 is moved in the horizontal direction perpendicular to the Z direction, the fitting relationship cannot be canceled, and both panels cannot be disassembled. A strong assembled state can be obtained. In addition, by shifting either panel in parallel with the Z direction, the fitting relationship can be easily eliminated and the panel can be removed.

  FIG. 40A and FIG. 40B are diagrams showing other structural examples.

FIG. When such a shape of the abutting portion is adopted, the airtightness of the heat insulating container is further improved, so that the heat insulating performance of the heat insulating container is improved.

In FIG. 43, a tapered surface having an inclination not perpendicular to the panel surface is formed on each of the end surface of the heat insulating portion 330 of the back panel 140 and the end surface of the heat insulating portion 330 of the left surface panel 130. It is a figure which shows the example made into the shape contact | abutted by.

  46, 47, and 48 are diagrams illustrating an example in which the side panel 110 is a partially connected panel. FIG. 46 shows a side panel 110C in which the left panel 130, the back panel 140, and the right panel 120 are connected by a connecting portion 361, and the front panel 150 that is a side panel 110D other than 110C. FIG. FIG. 47 is a diagram illustrating that the left side panel 130, the back panel 140, the right side panel 120, and the front panel 150, which are all of the side panels 110, are side panels 110C that are connected by a connecting portion 361. . 48, among the side panels 110, the side panel 110 </ b> C in which the left panel 130 and the back panel 140 are coupled by the coupling unit 361, the front panel 150, and the right panel 120 are coupled by the coupling unit 361. It is a figure which shows that it is side panel 110D other than 110C.

In particular, by configuring the connecting portion 361 with a rotatable hinge or the like or with a hook-and-loop fastener or the like, the volume after folding can be reduced. Further, the panel to be connected is not limited to the side panel 110, and for example, any one of the side panels 110 and the top panel 170 may be connected.

(D) Modification of side panel (2)
A modified example of the heat insulating container that does not have the opening / closing part on the side panel will be described. FIG. 49 is a view showing a heat-insulating container 100D having no opening / closing part by a hinge or the like. The main points different from the heat insulating container 100 of the first embodiment described above are that the front panel 150 has no opening / closing part, and there is no front plate part 151, front door part 161, hinge 101 for rotating the front door part, or the like. It is. Since there is no opening / closing part, the strength of the side panel can be increased, so that it is possible to improve the load resistance when stacking two stages.

  In FIG. 50A, the foam heat insulating materials 332e and 332f are divided into two. A through-hole is formed in the foam heat insulating material 332e, and the vacuum heat insulating material 331 is fitted into the through-hole. Therefore, it becomes easy to form a structure in which the foam heat insulating material 332 is disposed on both sides of the end surface of the vacuum heat insulating material 331. The foam heat insulating material 332e and the foam heat insulating material 332f are fixed via an adhesive 336, and the outer peripheral portions of the foam heat insulating material 332e and the foam heat insulating material 332f are covered with the heat shielding sheet 333. For example, by using a weakly sticky adhesive as the adhesive 336, the vacuum heat insulating material 331 can be configured to be removable, and the vacuum heat insulating material can be easily replaced when it is damaged.

  50 (b) is the same as FIG. 50 (a) in that the two divided foam heat insulating materials 332e and 332f are used, but the adhesive 336 is discontinuously disposed on the foam heat insulating material 332f. In addition, a recess for applying the adhesive 336 is formed. Thereby, a heat bridge caused by the adhesive 336 having a relatively low heat insulating property can be suppressed.
