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.

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, top panel, or bottom panel of the heat insulation container includes a panel that can be opened and closed, and includes a door that can be opened and closed by rotating around the linear rotation center with respect to the plate. . The panel that can be opened and closed includes an outer panel and an inner panel arranged on the panel surface of the outer panel on the heat insulating space side. The inner panel includes a heat insulating portion including a vacuum heat insulating material. The outer panel includes a metal door portion frame portion disposed on the door portion. In the assembled state, the door frame portion does not contact the heat insulation space formed by the panel surface on the heat insulation space side of the side panel, the panel surface on the heat insulation space side of the top panel, and the panel surface on the heat insulation space side of the bottom panel. .

  The present disclosure also describes an insulated container that uses vacuum insulation 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, the top panel, or the bottom panel of the heat insulation container includes an openable / closable panel including a door portion that can be opened and closed by rotating around a linear rotation center in an assembled state. The openable and closable panel includes a heat insulating portion including a vacuum heat insulating material and a metal hinge disposed on the door portion. The hinge is in an assembled state, the panel surface on the heat insulating space side of the side panel, and the heat insulating of the top panel. It does not contact the heat insulation space formed by the panel surface on the space side and the panel surface on the heat insulation 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 particular, in an openable / closable panel having a door that can be opened and closed by rotating around a linear rotation center, a strong stress is applied to the end surface of the door when the panel of the heat insulating container in the assembled state is closed. There is a risk that the insulation panel will 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, the top panel, or the bottom panel includes an openable / closable panel including a door portion that can be opened and closed by rotating around a linear rotation center in an assembled state. Therefore, the heat-insulating container according to the present disclosure improves workability by, for example, opening the panel when performing an article loading / unloading operation.

  The openable / closable 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 panel that can be opened and closed includes a metal door part frame part that is arranged in the door part in an assembled state. Since the metal door frame portion supports, for example, its own weight and the load from the top surface side, the heat insulating container of the present disclosure has a good load resistance, and the heat insulating container is enlarged to try to stack it in two stages. Even if it is a case, the danger of a vacuum heat insulating material being damaged can be reduced.

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

  Moreover, it is a panel which can be opened and closed provided with the heat insulation part containing a vacuum heat insulating material, and you may provide the metal hinges arrange | positioned at a door part. Even when the heat insulation container is enlarged when the panel is opened, the weight of the door can be supported. A metal hinge 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 in the assembled state. Does not contact the heat insulation space. Therefore, it can suppress that heat is transmitted through a metal hinge 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 insulating container In the heat insulating container, the side panel, the top panel, or the bottom panel includes a plate portion that forms a wall surface in the assembled state, and the door portion includes the plate The outer panel includes a metal plate frame portion disposed on the plate portion, and the plate frame portion is in the assembled state, the side panel. It is good also as what does not contact the said heat insulation space formed by the panel surface by the side of the said heat insulation space of the said, the panel surface by the side of the said heat insulation space of the said top panel, and the panel surface by the side of the said heat insulation space of the said bottom panel. In addition to the metal door part frame part arranged in the door part, by providing the metal plate part frame part also on the plate part side, the strength of the panel that can be opened and closed is increased, and as a heat insulating container Improve load capacity. Furthermore, the metal door part frame part and the metal plate part frame part may be configured to contact each other in the assembled state when the door part is closed in the assembled state. By arranging the metal door frame part and the metal plate frame part in contact with each other, the external force load from the panel itself and other panels that can be opened and closed, from the upper side when stacked in two stages The load portion and the like can be supported by the door portion frame portion and the plate portion frame portion that are in contact with each other, and the load resistance can be increased.

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

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

  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. In the assembled state of the panel, the door portion may be disposed closer to the top panel than the plate portion. Since the height of the panel is lowered by opening the panel, for example, workability for putting in and out the article is improved. Further, in the assembled state, the length of the line of intersection between the outer surface of the door portion and the surface perpendicular to the linear rotation center is such that the outer surface of the heat insulating container and the surface perpendicular to the linear rotation center are It may be the same as or smaller than the length of the intersection line. When the panel is in an open state, the risk of the vacuum heat insulating material being damaged due to the door rubbing against the floor surface can be reduced. Alternatively, when the panel is opened and closed, the range of movement of the door is narrowed, so the work space required for the opening and closing work may be narrow, and the door hits something and the vacuum insulation is damaged. The risk of doing so can be reduced.

  The outer panel of the side panel has a portion not provided with the plate portion frame portion and the door portion frame portion, and may be provided with a protective material made of an organic polymer at the portion. Part and the door frame part to the sum of the area occupied 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 40% or less may be sufficient as the ratio of the area which the board part frame part and the said door part frame part occupy for 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.

  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 and a horizontal width of 916 mm to 1116 mm, a quadrilateral having a vertical width of 1100 mm to 1300 mm and a horizontal width of 900 mm to 1100 mm, a vertical width of 1100 mm to 1300 mm and a horizontal width of 700 mm or more In addition, a quadrilateral having a length of 900 mm or less and a quadrilateral having a vertical width and a horizontal width of 1065 mm or more and 1265 mm or less can be given. By making the shape of the side panel suitable for the shape of the standard pallet in each country, the efficiency of transportation and storage can be improved. Further, as the outer peripheral shape of the side panel of the heat insulating container, for example, when the assembled heat insulating container is viewed from the top surface side, a quadrilateral having a vertical width of 795 mm or more and 995 mm or less and a horizontal width of 644 mm or more and 844 mm or less. It is good. By making the dimensions suitable for the shape of a standard carriage, transportation and storage can be made more efficient.

  The heat insulating container may include a conductive material in contact with the heat insulating space. Since the heat insulation container of this indication is constituted so that a board part frame part and a door part frame part, or a hinge may not contact heat insulation space, there is 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.

(E) Example of heat insulation container of this indication Hereinafter, with reference to drawings etc., an example of the heat insulation container of this indication is explained. However, the heat insulation container of this indication is not limited to this example or the embodiment mentioned below.

  In addition, each figure shown below is shown typically. Therefore, the size and shape of each part are exaggerated as appropriate for easy understanding. Moreover, in each figure, the hatching showing the cross section of the member is omitted as appropriate. Numerical values such as dimensions and material names of the respective members described in the present specification are examples of the embodiment, and the present invention is not limited thereto, and can be appropriately selected and used. In this specification, terms specifying the shape and geometric conditions, for example, terms such as parallel, orthogonal, and vertical are intended to include substantially the same state in addition to being strictly meant.

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 will be 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. As shown in FIG. 1, the right panel 120, the left panel 130, the rear panel 140, and the front panel 150 that constitute the side panel 110 are all vertically centered about a point that is approximately half the height of each panel. The structure is divided into two. The lower half of each panel is a plate portion fixed to the heat insulating container 100, and the upper half is a door portion attached to the plate portion so as to be opened and closed by a hinge. In addition, the top panel 170 is also divided into two parts, the front side and the back side, around a point that is approximately half the length of the panel in the depth direction. It is attached to the back half plate part so that it can be opened and closed by a hinge. However, as will be described later, the back half plate portion can be opened and closed with respect to the front half door portion.

  As shown in FIG. 2, the right panel 120 includes a metal plate frame portion 410 extending in the lateral direction at the upper end portion of the plate portion constituting the lower half side, and is provided at the lower end portion of the door portion constituting the upper half side. A metal door frame portion 420 extending in the lateral direction is provided, and the plate portion frame portion 410 and the door portion frame portion 420 are in contact with each other along a boundary line between the plate portion and the door portion. Further, since the hinge 101 is attached to both the plate portion frame portion 410 and the door portion frame portion 420, the door portion of the right panel 120 can be rotated and opened with respect to the plate portion. . Although not shown, the left panel 130, the back panel 140, and the front panel 150 are similarly provided with a plate portion and a door portion that can be opened and closed with respect to the plate portion. The top panel 170 also includes a plate part frame part 410 and a door part frame part 420 in the vicinity of the boundary line between the plate part and the door part.

  The right panel 120 and the left panel 130 include a support part 310 and a frame part 320. The support frame 310 as a vertical frame and the frame unit 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 similarly include a 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 support part may be comprised and the other support part may be arrange | positioned in areas other than the frame of an outer side panel. Moreover, the ratio which a support part accounts in an outer side panel may be more or less than this example. The shape and arrangement of the support part are not particularly limited.

  In addition, in this indication, in order to make an understanding easy, the direction and position in heat insulation container 100 may be indicated as follows. The same applies to heat insulating containers 100A, 100B, 100C, 100D, 100E, 100F, 100G, 100H, 100I, 100J, 100K, 100L, 100M, 100N, 100P, 100Q, 100R, and 100S, which will be described later.

  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 right panel 120, the left panel 130, the back panel 140, the front panel 150, and the top panel 170 have a structure that can be partially opened and closed, and FIGS. 1 and 2 show a partially opened state. 1 and 2 is in an assembled state of a quadrangular prism structure by closing each panel, and the heat insulating space surrounded by the side panel 110, the top panel 170, and the bottom panel 190. Can be formed inside the container.

  As shown in FIG. 3, the heat insulating container 100 in the 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. 3, 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. 3, the front panel 150, the left panel 130, the back panel 140, and the right panel 120, which are the side panels 110, are respectively the outer panels 150B, 130B, 140B, and 120B and the inner panels 150A, 130A, 140A, And 120A. 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 FIG. 1 to FIG. 3, the right panel 120 is divided into two substantially in half, each having a lower half plate fixed to the heat insulating container 100 and a hinge to the plate. A door portion on the upper half side that can be rotated and opened. Further, the right panel 120 includes a metal plate portion frame 410 that is an upper end portion on the plate portion side and a metal door portion frame that is a lower end portion on the door portion side along the boundary line between the plate portion and the door portion. The plate portion frame portion 410 and the door portion frame portion 420 are in contact with each other in the assembled state of the heat insulating container 100. Although not shown, the same applies to the left panel 130, the back panel 140, and the front panel 150. The top panel 170 also includes a metal plate frame portion 410 and a door frame portion 420 that are in contact with each other along the boundary line between the back half and the front half.

  The side panel 110 can be opened and closed with the upper half side of each panel as a door portion, and a metal door portion frame portion 420 is provided on the door portion. The door frame portion 420 can increase the strength as a panel and the rigidity as a heat insulating container wherever it is provided in the door portion. However, in this embodiment, the door portion frame portion 420 is provided outside the door portion closest to the rotation center of the door portion. The door frame portion 420 is arranged so as to have an end portion along the edge. Taking the right panel 120 as an example, a door part frame part 420 having an end along the boundary line with the plate part 121, which is the outer edge side of the door part 122 closest to the rotation center with respect to the plate part 121, is arranged. Yes. However, in FIG. 3, the frame part 320 is arranged at the uppermost part of the door part 122, but this may be replaced with the door part frame part 420. In this case, the door frame portion is configured to have an end portion along the outer edge of the door portion farthest from the rotation center of the door portion.

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

  Thus, especially when the door is closed, the door frame portion 420 serves as a column or wall that supports the weight of the panel and the load from the top surface side, and suppresses the breakage of the vacuum heat insulating material. Furthermore, when the plate part frame part 410 is arranged at the end of the plate part that is adjacent to the door part frame part 420 as in the present embodiment, the door part frame part 420 and the plate part frame part 410 are separated from each other. By contacting each other, forces can be transmitted to each other, and the effect of dispersing the load to the surroundings is enhanced, so that further load resistance and suppression of breakage of the vacuum heat insulating material can be achieved. In addition, the metal plate part frame part and door part frame part arranged on the top panel also act as a beam to the side panel, support the load from the upper stage in the two-stage stacking, and suppress the damage of the vacuum insulation material To do.

  In addition, as shown in FIGS. 1 to 3, the heat insulation space 300 of the heat insulation container 100 is in an assembled state, inside the side panel 110, inside the top panel 170, and inside the bottom panel 190. It is formed by the panel surface. 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. Has been. The metal plate part frame part and the door part frame part constituting the boundary part between the plate part and the door part of each side panel or top panel are respectively arranged on the outer panels 120B, 130B, 140B, 150B, and 170B. Therefore, these metal plate | board part frame parts and door part frame parts do not contact the heat insulation space 300, but can maintain favorable heat insulation. The plate part frame part and the door part frame part may be disposed on the bottom panel 190, and the same applies to that case. Although the details will be described later, when the hinge that rotatably attaches the door portion to the plate portion is made of a strong metal, there is no metal plate portion frame portion or door portion frame portion described above. In addition, the side panel may not be a two-panel configuration of the outer panel and the inner panel.

  In the heat insulating container 100 of this example, each panel can be partially opened and closed, and when the door portion is closed, the door portion and the plate are interposed at the boundary portion between the plate portion and the door portion via the metal door portion frame portion. When the parts are in contact with each other, the weight of each panel and the load from the top surface received by the heat insulation container at the bottom of the two-stage heat insulation container can be supported, and the vacuum heat insulating material can be prevented from being damaged. . Furthermore, in this example, by providing a metal plate part frame part on the plate part side, the door part frame and the plate part frame are in contact with each other, further improving the load resistance and suppressing the damage of the vacuum heat insulating material. Can be obtained. 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 the metal board part frame part 410 and the door part frame part 420 do not contact the heat insulation space 300. FIG. By arrange | positioning in this way, it can suppress that the heat insulation performance of a heat insulation container falls.

  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. 5 is a diagram illustrating the heat insulating container 100 according to the first embodiment.

  The heat insulating container 100 is, for example, a container used for storage or transportation of luggage that needs to be kept cold or warm, such as a frozen product or a heated product. As shown in FIG. 5, 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.

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 in one insulated container, but also for loading platforms, containers, warehouses, etc. of transport machines such as trucks, railways, ships, and aircraft. It is also efficient for efficient storage in a limited space. The length of one side of the side panel of the heat insulating container is preferably approximated to the size of the pallet 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, the left panel 130, the rear panel 140, and the right panel 120, which are the four panels constituting the side panel 110 of the heat insulating container 100, are each divided into two in the vertical direction, and approximately half in the height direction of the panel. The upper half side of the panel can be partially opened and closed. In addition, the top panel 170 is also divided into two on the front side and the back side, and is joined by a hinge at a substantially half point in the depth direction of the panel, and the front half or the back half of the panel is partially opened and closed. It is possible.

  As shown in FIG. 3, the front panel 150, the left panel 130, the back panel 140, and the right panel 120 are plates 151, 131, 141, and 121 that are disposed on the lower side of each, and the upper side thereof. However, in the present disclosure, the front panel 150, the left panel 130, the back panel 140, and the right panel 120 are the respective plates 151, 131. 141 and 121 and 152, 132, 142, and 122 which are each door part, or one of them. Further, when the inner panels of the front panel 150, the left panel 130, the rear panel 140, and the right panel 120 are represented as 150A, 130A, 140A, and 120A, 151A, 131A, 141A, which are the respective plate side inner panels, and 121A and 152A, 132A, 142A, and 122A which are door side inner panels are pointed out. Similarly, when the outer panel is represented as 150B, 130B, 140B and 120B, it refers to 151B, 131B, 141B and 121B on the plate portion side and / or 152B, 132B, 142B and 122B on the door portion side. To do.

  The same applies to the top panel 170. The top panel 170 corresponds to a first upper plate portion 171 corresponding to a plate portion disposed on the back side and a door portion disposed on the front side thereof. Both or any one of the 2nd upper board parts 172 shall be pointed out. Further, when the inner panel of the top panel 170 is represented as 170A, it refers to either or either one of 171A that is the first upper plate portion side inner panel and 172A that is the second upper plate portion side inner panel, Similarly, when the outer panel is expressed as 170B, it is intended to indicate both or either 171B which is the first upper plate portion side outer panel and 172B which is the second upper plate portion side outer panel.

  The structure of the side panel 110 will be described using the front panel 150 as an example. As shown in FIG. 5, the front panel 150 is a panel that can be partially opened and closed by a hinge 101. With respect to a straight line m parallel to the Y direction passing through approximately half of the height direction, the half on the −Z direction side is the plate portion 151, the half on the + Z direction side is the door portion 152, and the door portion 152 is The hinge 101 is rotatably attached to a plate portion 151 fixed to the heat insulating container 100. Therefore, the door part 152 can be opened to the + X direction side, which is the front side, or can be returned and closed. Each of the upper end portion of the plate portion 151 and the lower end portion of the door portion 152 is provided with a metal frame portion having a certain height and extending in the lateral direction. The plate portion side is the plate portion frame portion 410 and the door portion side is the door portion frame portion 420, which are in contact with each other along a straight line m that is a boundary line.

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

  In addition, support portions 310 extending in a direction parallel to the Z direction are disposed at end portions 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. The other side panels, ie, the left panel 130, the back panel 140, and the right panel 120 have the same structure.

  As shown in FIG. 3, 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. 6-8 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. 6A, 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. 6B, the back panel 140 is placed 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. 7A, 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. 7B, 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. 8, the top panel 170 is placed above the four side panels 110 of FIG. 7B, 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. 8 is started, but the top panel 170 is removed, then the front panel 150 is removed as the reverse work of FIG. 7B, and then the reverse of FIG. 7A. As a work, the right panel 120 is removed. Further, as the reverse operation of FIG. 6B, the rear panel 140 is removed, and finally, as the reverse operation of FIG. 6A, the left surface panel 130 and the bottom panel 190 are removed, thereby completing the disassembly operation. .

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

  FIG. 9 is a side view of the disassembled panels stacked in a designated order. As shown in FIG. 9, in a state where the heat insulating container 100 is disassembled, for example, a bottom panel 190 composed of an inner panel 190 </ b> A is placed, and a left panel 130 is placed on the bottom panel 190. The back panel 140 is overlaid in the direction to become the outer panel 130B, and the back panel 140 is overlaid thereon in the direction to become the outer panel 140B on the lower 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. Further, by displaying the side of the stacked panels, a display for order identification that can clearly identify whether the panel stacking order is correct or not may be given. For example, numbers and letters can be assigned to the sides of each panel in order, or a design can be given so that the correct design can be recognized when correctly stacked, but the correct design cannot be recognized when stacked incorrectly. Or you may provide the predetermined | prescribed fitting structure so that a mutual panel may fit only when it correctly piles up on the specific outer panel which should be piled up facing each other.

(C) Front panel (i) structure The front panel 150 which is one of the side panels 110 among the panels which comprise the heat insulation container 100 is demonstrated. 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, all having the same structure. FIGS. 10A and 10B are views of the front panel 150 as seen from above in a direction perpendicular to the panel surface. 10A is a view of the front panel 150 as viewed from the + X direction side that is the outside of the heat insulating container 100, and FIG. 10B is a view of the front panel 150 from the −X direction side that is inside the heat insulating container. FIG.

  As shown in FIG. 10A, the front panel 150 is centered on a straight line m parallel to the Y direction, and a door portion 152 that is a + Z direction side panel and a plate portion 151 that is a −Z direction side panel. It is divided. The door portion 152 is attached to the plate portion 151 via a hinge 101 arranged on a straight line m, and the door portion 152 rotates with respect to the plate portion 151 so that it can be opened and closed around the straight m-axis. It is fixed as possible.

  As shown in FIG. 10A, when the door portion 152 and the plate portion 151 are viewed from the outside of the heat insulating container 100, the outer panel 152B on the + Z direction side and the outer panel 151B on the −Z direction side are respectively visually recognized. The The outer panel 152B includes a protection member 322, a support portion 310 disposed in a frame shape along the end of the outer panel 152B so as to surround the periphery of the protection member 322, and various frame portions. The various frame parts include a door part front end frame part 162 on the + Z direction side, a frame part 320 indicated by a broken line on the back side thereof, and a metal door part frame arranged as a horizontal frame near the straight line m on the −Z direction side. Part 420.

  The outer panel 151B is also composed of a protective member 322, and two support portions 310 and a frame portion arranged in a frame shape along the end of the outer panel 152B so as to surround the periphery of the protective member 322. The frame portion includes a metal plate portion frame portion 410 disposed as a horizontal frame near the straight line m on the + Z direction side, and a frame portion 320 on the −Z direction side.

  In FIG. 10B, when viewed from the inside, the front panel 150 has the inner panel 152A visually recognized on the + Z direction side and the inner panel 151A visually recognized on the −Z direction side. The inner panels 151 </ b> A and 152 </ b> A are configured by a heat insulating portion 330 including a vacuum heat insulating material 331. In addition, outside the outer peripheries of the inner panels 152A and 151A, the support part 310 and the frame part 320 disposed at the end parts of the outer panels 152B and 151B are visually recognized. The outer peripheral dimensions of the inner panels 152A and 151A are smaller than the outer peripheral dimensions of the outer panels 152B and 151B, respectively, and the inner panels 152A and 151A are disposed within the panel surface of the outer panels 152B and 151B. Since the edge part of an inner side panel is protected by the edge part of an outer side panel, it can prevent that the vacuum heat insulating material of an inner side panel is damaged. Furthermore, by making the dimensional difference in consideration of the panel thickness, one end of the inner panel of the rear panel is brought into close contact with the end of the inner panel of the left panel, and the other end of the inner panel of the right panel is fixed. When closely attached to the end portion, the end portion of the outer panel of each panel can be configured to be in close contact, and the heat insulating property of the heat insulating space can be improved with the heat insulating container in the assembled state.

  When the left panel 130 and the right panel 120 adjacent to the left and right of the front panel 150 are panels that are not partially opened and closed like the front panel 150, the height of the outer panel of the front panel 150 that can be opened and closed is The height of the outer panels of the left panel 130 and the right panel 120 may be lower. In this case, the position of the end surface on the top surface side of the front panel 150 is lower than the positions of the end surfaces of the left panel 130 and the right panel 120 in the assembled heat insulating container. Therefore, even if the end surface of the side panel is bent due to the weight of the top panel 170 or the weight of another heat insulating container when stacked in two stages, the opening and closing of the front panel 150 is not hindered.

(Ii) Inner panel The structure of the inner panel 150A will be described. As shown in FIG. 10B, the inner panel 150 </ b> A is divided into an inner panel 151 </ b> A of the plate portion 151 and an inner panel 152 </ b> A of the door portion 152. Inner panel 151A and 152A are comprised from the heat insulation part as mentioned later. FIG. 11A and FIG. 11B are cross-sectional views of the heat insulating portion 330. 12A and 12B are sectional views of the vacuum heat insulating material 331 included in the heat insulating portion 330. FIG. FIG. 13A and FIG. 13B are cross-sectional views of the front panel 150 taken along a cross section perpendicular to the Y direction, taken along arrow AA of the front panel 150 of FIG.

  FIG. 11A 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.11 (a), the vacuum heat insulating material 331 is protected by the outer side panel arrange | positioned on the opposite side to heat insulation space. In addition, although not shown in figure, the protective base material mentioned later may be arrange | positioned on the opposite side to the heat insulation space of the vacuum heat insulating material 331.

  When forming the heat insulating portion 330 shown in FIG. 11 (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 fitted 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. 11B 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 protective base material 338 that surrounds the foam heat insulating material 332, and the heat shield sheet 333 further includes a protective base for the heat insulating part 330. Surrounding the material 338. 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 heat insulating sheet 333 surrounding the foam heat insulating material 332, and a protective base material 338 surrounding the heat insulating sheet. You may be comprised from. As the protective substrate at this time, for example, a protective material made of an organic polymer for an outer panel described later can be used.

  As shown in FIG. 12A, 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. 12B is another example of the vacuum heat insulating material 331. In FIG. 12A, gaps are formed at both ends inside the vacuum heat insulating material 331. In FIG. 12B, 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.

Gas barrier properties of the outer package 331b is oxygen permeability 0.5cc · m ^-2 · day ^-1 or less, or may be inter alia 0.1cc · m ^-2 · day ^-1 or less. Further, the water vapor permeability 0.2cc · m ^-2 · day ^-1 or less, or may be inter alia 0.1cc · m ^-2 · day ^-1 or less.

The internal vacuum degree of the vacuum heat insulating material 331 may be 5 Pa or less, for example. The initial thermal conductivity of the vacuum heat insulating material 331 is, for example, 15 mW · m ⁻¹ · K ⁻¹ or less, particularly 10 mW · m ⁻¹ · K ⁻¹ or less, particularly 5 mW · m ⁻¹ · K ^{−1 in a} 25 ° C. environment. It may be the following.

  The foam heat insulating material 332 can be disposed so as to be bonded adjacent to at least the main surface of the vacuum heat insulating material 331 on the heat insulating space side. As the foam heat insulating material 332, a known foam heat insulating material can be used, and for example, a polyurethane foam may be used.

  The heat shielding sheet 333 can be disposed so as to cover the entire adjacent vacuum heat insulating material 331 and foam heat insulating material 332. Examples of the heat shielding sheet 333 include a multilayer sheet including a metal foil, a vapor deposition sheet in which a vapor deposition layer is formed on one side of a resin sheet, and the like.

  The heat insulating part 330 can be configured such that the vacuum heat insulating material 331 is visible from the outside. 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.

  FIG. 13A is a cross-sectional view of the front panel 150 when the door 152 is closed, and FIG. 13B is a cross-sectional view when the door 152 is opened. In the present embodiment, as shown in FIG. 13A, the heat insulating portion 330 having the structure described in FIG. 11A is used as the inner panel 151A of the plate portion 151 and the inner panel 152A of the door portion 152. .

  In FIG. 13A, the heat insulating portion 330 constituting the inner panel 151 </ b> A of the plate portion 151 is arranged so that the foam heat insulating material 332 is adjacent to the heat insulating space side of the heat insulating container 100. By doing so, the risk of the vacuum heat insulating material 331 being directly damaged by reducing the amount of the article against the inner panel 151 when the article is put into and taken out of the insulated container 100 after assembly is reduced. Further, the + X direction side which is the outside of the inner panel 151 is joined to a plate part frame portion 410 which is a constituent member of the outer panel 151B described later via an adhesive 334, and the outer side of the vacuum heat insulating material 331 is the plate part frame portion. Since it is protected by a protective material 322 bonded to 410, the vacuum heat insulating material 331 is not easily damaged even when an external force load is applied. The same applies to the door portion 152.

(Iii) Outside Panel As shown in FIG. 10A, the outside panel 150B is divided into an outside panel 151B of the plate portion 151 and an outside panel 152B of the door portion 152. The outer panel 151B includes a protective member 322, two left and right support portions 310 arranged as vertical frames along the end of the outer panel 152B surrounding the protective member 322, and a straight line m near the + Z direction side. It is comprised from the metal board part frame part 410 arrange | positioned as a horizontal frame, and the frame part 320 of the -Z direction side. In addition, the outer panel 152B is a horizontal frame on the + Z direction side, two support portions 310 arranged as a vertical frame along the edge of the outer panel 152B surrounding the periphery of the protective material 322 and the protective material 322. The door portion front end frame portion 162, a frame portion 320 disposed on the back side thereof, and a metal door portion frame portion 420 disposed as a horizontal frame near the straight line m on the −Z direction side.

  Further, as shown in FIG. 13A, the protective member 322, which is a constituent member of the outer panel 151B, is bonded to the + X direction side that is the outer side of the inner panel 151A including the heat insulating portion 330 including the vacuum heat insulating material 331. The plate portion frame portion 410 is fitted and fixed at the upper end portion with the groove portion 410c interposed therebetween. Further, the protective member 322, which is a constituent member of the outer panel 152B, is disposed on the + X direction side, which is the outer side of the inner panel 152A composed of the heat insulating portion 330, and the door portion frame portion with the groove portion 420c at the lower end thereof. 420 is fixedly fitted. Further, a hinge 101 is attached to the outside of the plate part frame part 410 and the door part frame part 420. As a result, the plate portion 151 and the door portion 152 are connected, and the door portion 152 can be rotated with respect to the plate portion 151, thereby opening the door portion 152 in the + X direction side as shown in FIG. 13B. be able to.

  In the state where the door 152 is closed as shown in FIG. 13A, the plate portion frame portion 410 located at the upper end portion of the plate portion 151 and the door portion frame portion 420 located at the lower end portion of the door portion 152 are mutually connected. The plate portion frame portion 410 and the door portion frame portion 420 which are metal members in the contact state can support the weight of the door portion 152 and the load of the upper step portion when stacked in two stages. It is possible to suppress the deflection of the heat insulating container due to vibration during transportation.

  Moreover, when the door part 152 is closed, between the board part frame part 410 and the door part frame part 420, and heat insulation space is separated by the heat insulation part 330 which comprises inner side panels 151A and 152A, Since the end surfaces are in contact with each other, the plate portion frame portion 410 and the door portion frame portion 420 do not contact the heat insulating space. As a result, even if a metal material having high thermal conductivity giving priority to strength is used as a constituent member of the plate part frame part 410 and the door part frame part 420, heat is transmitted to the heat insulation space surrounded by the heat insulation part 330. Since it is difficult, the fall of the heat insulation performance of the heat insulation container 100 can be suppressed.

  As a constituent member of the plate part frame part 410 and the door part frame part 420, metal materials in general can be applied. For example, iron, stainless steel, aluminum, aluminum alloy, copper, brass, titanium, zinc, or the like can be used.

  Further, although it is not essential to include the support portion 310 and the frame portion 320, as in the present embodiment, as a part of the outer peripheral frame of the plate portion 151 and the door portion 152, the vertical support portion 310 and the lateral direction are provided. If the frame portion is configured to be connected to the plate portion frame portion 410 and the door portion frame portion 420, the load resistance as the entire heat insulating container can be further improved. The support part 310 and the frame part 320 may or may not be the same material. For example, various materials such as metal materials, organic polymer materials, ceramic materials, and carbon fibers, and composite materials thereof. Is applicable. If it is a metal material, for example, iron, stainless steel, aluminum, aluminum alloy, copper, brass, titanium, zinc and the like can be used. As long as it is an organic polymer material, for example, acrylonitrile / butadiene / styrene (ABS), polycarbonate, acrylic resin, fiber reinforced plastic (FRP), or the like can be used.

  The protective material 322 will be described. When used as a constituent member of the outer panel, the protective material 322 protects the vacuum heat insulating material 331 of the inner panel, and the plate portion frame portion 410, the door portion frame portion 420, the support portion 310, and the frame at the end portions thereof. The portion 320 can be disposed to provide rigidity as a surface of the entire outer panel. The protective material 322 may be made of a material having low thermal conductivity in order to enhance heat insulation. For example, organic polymer materials such as plywood, foam material, resin plate, embossed resin sheet, paperboard, ceramic members, and the like can be used. Plastic cardboard or cured wood can be used as a lightweight and relatively rigid material. The protective material 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. For example, a hook-and-loop fastener or a double-sided tape may be used so that the heat insulating portion can be easily attached and detached. By making it 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.

(D) Left panel, right panel, rear panel Since the left panel 130, the rear panel 140, and the right panel 120 other than the front panel 150 have the same configuration as the front panel 150, description of each panel is omitted.

FIG. 14B is an enlarged view of a portion near the portion B in FIG. 14A 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. 14A, the side panel 110 is disposed so that the end surface of the inner panel 150A of the front panel 150 and the panel surface of the inner panel 130A 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. It is the expanded sectional view cut in the section perpendicular to the Z direction in the part of the screw joint part 341 to join.

  Thereby, each panel of the side panel 110 can have the same size, arrangement, and structure of the outer panel and the inner panel, and the panel parts can be shared. Moreover, the stock of spare parts, such as an outer side, an inner side panel, a heat insulation part, a vacuum heat insulating material, can be reduced, and parts replacement | exchange and repair work become easy. Even in the assembly work, for example, even if the left panel 130, the back panel 140, and the right panel 120 are misplaced, they can be assembled without any problems, have no functional problems, and can improve workability and convenience. . The arrangement of each panel is not limited to that shown in FIG. 14A. For example, the arrangement is such that the panel surface of the inner panel 130A of the left panel is in contact with the end surface of the inner panel 140A of the rear panel 140. It is also possible to take a method.

  The detailed structure of the support part 310 is demonstrated.

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 support portion 310, is fitted and fixed to the front end 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 similar to the left panel 130. 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. A partial support portion 310b, which is a constituent member of the 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. 14B, 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 portion 310a of the left panel 130 and the rear panel 140 partial support portion 310b are in contact with each other to form an integral support portion 310. The support portion 310 is perpendicular to the panel surface of the bottom panel 190. Furthermore, it extends continuously from the end on the top panel 170 side to the end on the top panel 170 side from the end on the bottom panel 190 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. .

(E) Top panel The top panel 170 will be described. 15A and 15B are views of the top panel 170 viewed from above in a direction perpendicular to the panel surface. FIG. 15A illustrates the top panel 170 outside the heat insulating container 100. FIG. It is the figure seen from a certain + Z direction side, and FIG.15 (b) is the figure which looked at the top panel 170 from the -Z direction side which is an inner side of a heat insulation container.

  As shown in FIG. 15A, the top panel 170 is divided into two on a straight line n parallel to the Y direction, and the first upper plate portion 171 corresponding to the plate portion and the second upper plate corresponding to the door portion. Part 172. The first upper plate portion 171 and the second upper plate portion 172 have a straight line n via a hinge 102 disposed on a straight line n parallel to the Y direction, which is a substantially half point of the depth in the X direction of the top panel. The shafts are fixed so as to be rotatable around each other. When viewed from the outside of the heat insulating container 100, the top panel 170 is visually recognized as an outer panel 170B. The outer panel 170B is divided into an outer panel 171B of the first upper plate portion 171 and an outer panel 172B of the second upper plate portion 172. The outer panel 170B surrounds the protective material 322 and the periphery of the protective material 322, respectively.

Each dimension of the outer periphery of the inner panel 170A of the top panel is also made smaller than each dimension of the outer periphery of the outer panel 170B, like the side panel.

  The top panel 170 opens or rotates to the original position by rotating the second upper plate part 172 in the + Z direction around the straight n-axis while holding the first upper plate part 171 on the side panel 110. It can be opened and closed. Alternatively, although not shown, the first upper plate portion 171 can be opened and closed while the second upper plate portion 172 is held on the side panel 110. Even after the heat insulating container 100 is assembled, the second upper plate portion 172 or the first upper plate portion 171 can be opened to load / unload the luggage. 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 100, the top panel can be removed from the side panel after the top panel is folded as shown in FIG. Moreover, when assembling the heat insulation container 100, the side panel can be opened after the top panel in a folded state is placed on the side panel as shown in FIG. Since the top panel can be raised and lowered with the top panel folded, work efficiency and safety can be improved.

  A state where the top panel 170 is placed on the side panel 110 will be described. FIG. 16A and FIG. 16B are a front view and a cross-sectional view regarding an adjacent portion between the top panel 170 and the left panel 130. FIG. 16A is a diagram showing the heat insulating container 100 viewed from the + X direction when the front panel 150 is removed. FIG. 16B is an enlarged cross-sectional view of the vicinity of the portion C in FIG.

  In FIG. 16A, the left panel 130, the top panel 170, the right panel 120, and the bottom panel 190 are arranged on the panel surface of the inner panel 130A of the left panel 130, on the end surface of the inner panel 170A of the top panel 170, It arrange | positions so that the end surface of the inner side panel A of the bottom panel 190 may contact | abut. The end surface of the inner panel 170A of the top panel 170 and the end surface of the inner panel A of the bottom panel 190 are disposed so as to contact the panel surface of the inner panel 120A of the right panel 120.

  As shown in FIG. 16B, as the configuration of the left panel 130, 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 toward 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 frame part 320 is fitted and fixed to the front end of the protective material 322 in the + Z direction with a groove part 320c therebetween. As a configuration of the adjacent top panel 170, there is a heat insulating portion 330 similar to the left panel 130. On the + Z 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. The frame part 320 is fitted and fixed to the front end of the protective material 322 in the −Y direction with a groove part 320c therebetween.

It is in contact with the end surface 330 a and maintains the heat insulating property of the heat insulating space surrounded by the heat insulating portion 330. Further, the top panel 170 is placed on the upper side of the left panel 130, that is, on the + Z direction side, and is in contact with the left panel by its own weight, but the placement position is not shifted along the plane perpendicular to the + Z direction. The positional deviation is regulated by the top surface guide portion 351. However, like the left panel 130 in FIG. 16B, the side panel with the top guide 351 projecting downward interferes with the top panel guide when the door 132 is opened. Before opening the door, it is necessary to open either the first upper plate 171 or the second upper plate 172 of the top panel 170 first so that the top guide does not interfere.

(F) Bottom Panel The bottom panel 190 will be described. The bottom panel 190 in this embodiment is configured by an inner panel 190A having the same structure as the inner panel 170A of the top panel 170. Since the bottom panel does not have a structure corresponding to the outer panel 170B of the top panel 170, the heat insulating container can be reduced in weight, the storage capacity of the assembled heat insulating container can be increased, and the disassembled state can be obtained. The heat insulation container can be made compact.

  The state of the bottom panel 190 placed on the pallet 500 and the adjacent portion of the left panel 130 will be described. FIG. 17 is a cross-sectional view of the adjacent portion between the bottom panel 190 and the left panel 130, and is an enlarged cross-sectional view of the vicinity of portion D in FIG.

  In FIG. 17, the frame part 320 is fitted and fixed at the −Z direction end of the protective material 322 constituting the outer panel 130 </ b> B of the left panel 130 with a groove part 320 c therebetween. A side guide part 352 is attached to the outside of the frame part 320 via an adhesive 335 as a protruding part toward the pallet 500. Since the side surface guide part 352 is attached in a shape that protrudes downward along the side surface of the pallet 500, the side surface panel 110 as a whole is restricted from shifting in the horizontal direction with respect to the pallet 500. In FIG. 19, the side guide part 352 is joined to the frame part 320 with an adhesive 335, but the joining means is not limited to the adhesive, and may be screw fastening, riveting, welding, or the like. In addition, the surface 330b of the heat insulating portion 330 that is the inner panel surface of the inner panel 130A of the left panel 130 is in contact with the end surface 330a of the heat insulating portion 330 that is the end surface on the −Y direction side of the inner panel 190A of the bottom panel 190. The heat insulating property of the heat insulating space surrounded by the heat insulating portion 330 is maintained.

  Although not shown in the drawings, the description of the adjacent portion between the left panel 130 and the top panel 170 and the description of the adjacent portion of the left panel 130, the bottom panel 190, and the pallet 500 are other related. The same applies to adjacent portions.

  Further, in order to prevent damage to the inner panel 190A caused by placing an article directly on the inner panel 190A of the bottom panel 190, an additional protective sheet may be disposed on the inner panel 190A. The material of the protective sheet is not limited, but an organic polymer sheet such as a plastic cardboard sheet or a plate-like wood sheet can be used.

(G) Pallet The pallet 500 will be described. A general pallet 500 can be used. In the heat insulating container 100 of the present embodiment, a lightweight and rigid plastic T11 type flat pallet is used, but is not particularly limited, for example, plastic, metal such as aluminum and aluminum alloy, wooden, cardboard And various sizes of pallets.

(H) Thermal insulation space The top panel 170, the side panel 110, and the bottom panel 190 have inner panels 170A, 110A, and 190A, respectively. Each inner panel 170A, 110A, 190A is comprised of a heat insulating part. The inner panel 110 </ b> A of the side panel 110 includes a heat insulating part 330 including a vacuum heat insulating material 331. When these panels are in the assembled state, as described with reference to FIG. 3, the heat insulation space 300 is formed as a substantially rectangular parallelepiped space by the panel surface of each inner panel. Since the periphery of the heat insulating space 300 is surrounded by a heat insulating material, inflow and outflow of heat from the outside are limited, and heat insulating properties can be maintained.

(I) Conductive material The form which attached the electroconductive sheet 701 for reducing the accumulation | storage of static electricity to the heat insulation container 100 is demonstrated. FIG. 18A, FIG. 18B, and FIG. 19 are views showing a state in which a conductive sheet 701 is attached to the heat insulating container 100 of the present embodiment. FIG. 18A 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. 18B is an enlarged cross-sectional view of FIG. 18A taken along the cross section perpendicular to the Z direction at the position of the panel surface inside the bottom panel 190, as viewed from the + Z direction.

  As shown in FIGS. 18A and 18B, 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 outside the heat insulating container 100. 731, and both 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.

  18 (a) and 18 (b), when an article is put in the heat insulating container 100, the article is electrically connected to the conductive sheet 701 laid on the upper part of the bottom panel 190, and the cable is electrically connected thereto. It is electrically connected to the ground connection part 731 outside the heat insulating container 100 through the part 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. 19 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. Since each side panel is separated into a lower plate portion and an upper door portion, the conductive sheet 701 is made of a flexible material from the inner surface of the plate portion to the inner surface of the door portion. It may be arranged as a shape that covers the entire area, or may be arranged as a sheet divided into a part corresponding to the plate part and a part corresponding to the door part. In the case where the conductive sheet is divided and arranged, wirings connected to the conductive mat 732 from the individual conductive sheets 701 may be individually arranged to form a plurality of cable portions 720, or each of the conductive sheets inside the heat insulating container. After the sheets 701 are partially connected and electrically connected, the cable portions 720 may be arranged in one.

  As shown in FIG. 19, by attaching 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 luggage 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 organic polymer material mixed with a material such as aluminum, gold, zinc or the like deposited on a resin sheet, acrylonitrile / butadiene / styrene (ABS), polystyrene, acrylic resin or the like is mixed. Various types can be used, such as a polymer alloy type obtained by mixing carbon black with an organic polymer material.

3. Second Embodiment (a) Structure of Thermal Insulation Container A second embodiment will be described. FIG. 20 is a diagram illustrating a heat insulating container 100B according to the second embodiment of the present disclosure. In the heat insulating container 100B, the door portion 152 and the second upper plate portion 172 of the front panel 150 and the top panel 170, respectively. It is a figure which shows the state which opened. The state where the door is closed has the same appearance as FIG. 5 showing the first embodiment. FIG. 21 is a cross-sectional view of the heat insulating container 100B in which the front panel 150 is cut along a cross section perpendicular to the Y direction at the arrow AA of the front panel 150 in FIG. 5, and FIG. FIG. 21B is a cross-sectional view when the door 152 is opened.

  The difference from the first embodiment is that, in the cross section in which the front panel 150 is orthogonal to the rotation center axis m, the boundary surface between the plate portion 151 and the door portion 152 in the closed state of the door portion 152 is not on the same plane. is there.

(B) Modification of Front Panel As shown in FIG. 21A, the plate portion 151 of the front panel 150 includes, in order from the −X direction, a heat insulating sheet 333, a foam heat insulating material 332, and a vacuum heat insulating material 331. The heat insulating portion 330 is configured, the plate portion frame portion 410 joined to the heat insulating portion 330 via the adhesive 334, and the outer panel 151B that is fitted to the plate portion frame portion 410 with the groove portion 410c interposed therebetween. A certain protective material 322 is arranged. Further, the door 152 has the same configuration, and the same heat insulating part 330 as the plate part 151, the door part frame part 420 joined to the heat insulating part 330 via the adhesive 334, and the door part frame part 420. A protective member 322, which is a constituent member of the outer panel 152B fitted with the groove 420c therebetween, is disposed. The plate part frame part 410 and the door part frame part 420 are fixed rotatably by a hinge 101.

  Further, as shown in FIG. 21 (a), the boundary surface between the plate portion frame portion 410 and the door portion frame portion 420, which is a boundary surface between the outer panel 151B of the plate portion 151 and the outer panel 152B of the door portion 152 seen in a cross section. Since the boundary surface of each heat insulating portion 330, which is the boundary surface between the inner panel 151A of the plate portion 151 and the inner panel 152A of the door portion 152, is formed at a different position in the Z direction, the plate portion 151 and the door portion The boundary surface 152 is not on the same plane. Thereby, in the state which closed the door part 152, 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 vicinity of the boundary surface between the plate portion frame portion 410 and the door portion frame portion 420, and the vicinity of the boundary surface of each heat insulating portion 330, which is the boundary surface between the inner panel 151A of the plate portion 151 and the inner panel 152A of the door portion 152, Since each of them is a place where the heat insulating performance is lower than other parts, the heat insulating part including the vacuum heat insulating material 331 in the heat insulating reduced area near the boundary surface between the plate part frame part 410 and the door part frame part 420 The arrangement of 330 also has an effect of suppressing a heat bridge caused by overlapping heat insulation performance degradation regions.

  FIG. 21B is a diagram showing a state in which the door portion 152 is opened. FIG. 22 is a perspective view showing a state in which the door portion 152 is opened based on the cross section of FIG. As shown in both figures, when the door portion 152 is open, the end portions of the plate portion 151 and the adjacent portion of the door portion 152 are gradually lowered from the −X direction to the + X direction stepwise. 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 object hits the inner panel 152A protruding upward from the outer panel 152B of the door 152 during the loading / unloading operation of the article. The purpose is to call attention to prevent damage to the vacuum heat insulating material of the inner panel 152A. Further, in the present embodiment, the place where the warning tape 103 is affixed is the back side when the heat insulating container 100B is viewed from the X direction, that is, the door 152 is opened from the front panel 150 and the article is taken in and out. 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 door portion 152, as shown in FIG. 3, at the positions outside the plate portion 151 and the door portion 152 and facing each other when the door portion 152 is opened, A buffer material 104 is provided. Even if the operator pinches his / her finger when closing the door 152, damage can be reduced.

4). 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) Modification Example of Opening / Closing Structure In the first and second embodiments, the lower plate portion and the upper door portion of the side panel having the opening / closing portion are mutually connected when the side panel is viewed in plan from the panel surface. Although the door portions open and close with the substantially same area as the rotation axis at approximately half of the height direction of the panel, the structure of the plate portion and the door portion is not limited to this. For example, the length of the line of intersection between the outer surface of the door portion and the surface perpendicular to the linear rotation center of the rotatable door portion is the intersection of the outer surface of the heat insulating container and the surface perpendicular to the linear rotation center. It may be less than or equal to the length of the line. In this case, when the panel is in the open state, the door can be rubbed against the floor surface to reduce the risk of damaging the vacuum heat insulating material, or the door moves when the panel is opened and closed. Since the range becomes narrow, the work place necessary for the opening and closing work may be narrow, and the risk of the vacuum heat insulating material being damaged due to the door hitting something can be reduced.

  Furthermore, when the side panel is viewed in plan from the panel surface, the area of the door part that can be rotated and opened with respect to the plate part is the area of the side surface of the heat insulating container including the door part, the plate part, and the side part of the pallet. It is good also as 1/2 or smaller than this. When the plate part is located on the lower side of the side panel and the door part is located on the upper side, even when the door part is fully opened, the tip of the door part includes the pallet before the floor surface. Since it contacts the side surface of the heat insulating container, the risk of the door portion colliding with the floor surface and being damaged can be reduced. In addition, when the side panel is viewed in plan from the panel surface, the area of the door part that can be rotated and opened with respect to the plate part is the area of the side surface of the heat insulating container including the door part, the plate part, and the side part of the pallet. It may be larger than 1/2. In this case, when the door part is fully opened, the tip of the door part may collide with the floor surface, so it is necessary to be careful when opening and closing it. can do. The above is an explanation in the case where the plate portion is disposed on the lower side of the side panel and the door portion is disposed on the upper side. For example, the plate portion is disposed on the right side of the side panel, and the horizontal direction of the panel with respect to the plate portion If the door portion that can be opened and closed by rotating about a rotation axis parallel to the Z direction is provided, the above description can be replaced with the relationship between the width of the door portion and the plate portion. . Modification examples relating to the structure of the plate part and door part of the side panel including these will be described below.

  In the heat insulating container 100 </ b> C of FIG. 23A, the dimension on the Z direction side that is the height of the door part 152 of the front panel 150 is smaller than the dimension on the Z direction side that is the height of the plate part 151 on the lower side. It has become a thing. In this case, since there is a baggage or another heat insulating container around the heat insulating container 100C and the workability is poor, a sufficient working space can be secured around the heat insulating container C when the door is opened. Opening and closing and loading and unloading can be done smoothly. Moreover, since the weight of the door part 152 becomes light, the work load accompanying the opening / closing operation | work of an operator's door part can be reduced. Moreover, when the door part is opened, the front end of the door part does not rub against the floor surface, and the vacuum heat insulating material inside the panel can be hardly damaged. Furthermore, the arrangement position of the board part frame part 410 and the door part frame part 420 can be made higher with respect to the height direction of the heat insulating container 100C, so that the upper heat insulating container to be supported by the board part frame part 410 and the door part frame part 420 is supported. Since the weight of the member can be reduced, the load applied to the plate portion frame portion 410 and the door portion frame portion 420 can be reduced. Therefore, the rigidity of the plate part frame part 410 and the door part frame part 420 can be lowered, and the weight of the member can be reduced. In addition, the board part frame part 410 does not need to be provided, and in that case, the metal door part frame part 420 serves to increase the strength of the front panel 150. Further, the height of the door portion 152 of the heat insulating container 100C includes the front panel 150 of the heat insulating container 100C obtained by adding the height of the door portion 152, the height of the plate portion 151, and the height of the side surface of the pallet 500. The effect described above can be obtained by setting the height of the side surface to ½ or less.

  Conversely, in the heat insulating container 100D of FIG. 23B, the height of the door portion 152 of the front panel 150 is made smaller than the height of the plate portion 151 on the lower side. In this case, after assembling the heat insulating container 100D, when it is desired to take in and out a large baggage, the baggage can be easily taken in and out without disassembling the heat insulating container, and workability is improved. Also, when the door is opened, the tip of the door hits the floor before it hits the panel surface of the plate, so the point that touches the floor before the door is fully opened at an angle of 180 degrees. Can fix the position of the door. Therefore, the load of the door opening / closing operation can be reduced. Furthermore, even when the door is opened vigorously, the panel surface of the door portion does not hit the panel surface of the plate portion, so that the risk of damaging the vacuum heat insulating material inside can be reduced. In addition, when the heat insulating container 100D is arranged on the upper stage side when the two-stage stacking is performed, the door part can be opened until it completely contacts the plate part, and a large luggage is taken in and out of the upper stage. Workability is improved. Moreover, the height of the door part 152 of the heat insulation container 100D includes the front panel 150 of the heat insulation container 100D in which the height of the door part 152, the height of the plate part 151, and the height of the side surface of the pallet 500 are added together. The effect described above can be obtained by setting it to be larger than ½ of the height of the side surface.

  24A has a structure in which the door 152 of the front panel 150 is substantially the entire surface of the front panel 150, and the entire panel can be opened to the front side. In this case, the plate part 151 may or may not exist as a panel shape. For example, the door part frame part 420 arranged at the lower end of the door part 152 and the lower pallet 500 are connected to the hinge 101. You may connect directly with. In this case, the plate portion is the pallet 500, and the pallet 500 itself also has the function of the plate portion frame. Also in this aspect, after assembling the heat insulating container E, when it is desired to take in and out a large load, the work can be easily performed without disassembling the heat insulating container, and workability is improved. Furthermore, since the rigidity of the pallet can be utilized by directly connecting the hinge 101 to the pallet 500 without the plate part frame part 410, the load resistance of the contact part between the door part frame part 420 and the pallet 500 can be improved. Can do.

  Further, in the heat insulating container 100P of FIG. 31A, the plate portion is not the pallet 500, but the plate portion frame portion 410 having the outer frame structure of the front panel 150 as the plate portion is provided at the lower end portion of the front panel 150. The door portion 152 includes a door portion frame portion 420 that comes into contact with the plate portion frame portion 410 at the rotation center of the hinge 101 and leaves a fixed outer frame structure on the left and right and upper ends of the front panel 150. 152 can be opened to the near side. Since there is an outer frame structure on the outer periphery of the front panel 150 in addition to the door frame 420, the rigidity of the panel can be increased.

  Further, in the heat insulating container 100F of FIG. 24B, in order to improve the workability of opening and closing the front panel 150, the diagonal lines of the panels are opened and closed on both sides of the left panel 130 and the right panel 120. A substantially triangular plate part, a door part, and a hinge are provided so as to be a rotation axis. In this case, first, the door 122 of the right panel 120 is opened while being rotated in the + Y direction side from the + X direction side and the + Z direction side toward the −X direction side and the −Z direction side. Next, the left panel is similarly opened while rotating the door part toward the -Y direction from the front side and the upper side to the back side and the lower side, and finally the door part 151 of the front panel 150 is opened to the front side. . By doing so, even when a large baggage is already stored on the front side inside the heat insulating container 100F, the additional baggage can be stored obliquely to the left or right rather than from the front in the + X direction side. . Further, it becomes easy for a plurality of workers to hold and store a heavy load, and workability is improved.

  Further, as in the heat insulating container 100Q of FIG. 31B, the door portion 152 that opens to the front side does not need to be able to open and close all sides when the front panel 150 is divided into two, and the front portion 150 has a front portion inside the plate portion 151. A door 152 having a size slightly smaller than the size of the panel 150 may be provided. Also in this case, it is necessary to provide the door part frame part 420 at any part of the door part 152. In this example, the door part frame part 420 is provided at the end opposite to the rotation center of the hinge 101 of the door part 152. It is arranged at a certain upper end. Thereby, the strength at the contact portion between the door portion 152 and the plate portion 151 in a state where the door portion 152 is closed can be improved, and the rigidity of the front panel 150 can be increased. The door frame portion 420 may be formed at the lower end portion of the door portion 152 that contacts the rotation center of the hinge 101.

  In 1st, 2nd embodiment and each above-mentioned modification, the board part fixed to a heat insulation container is arrange | positioned at the downward side, and the door part which can be opened and closed is arrange | positioned at the upper side. However, arrangement | positioning of a board part and a door part is not limited to this, For example, the door part which can be opened and closed is arrange | positioned at the downward side, and the fixed board part may be arrange | positioned at the upper side. In this case, it becomes easy to store a heavy load that is difficult to lift in the assembled heat insulating container. In addition, for example, when a cooling agent is stored in a heat insulating container, moisture generated by condensation can be easily discharged to the outside by opening the door portion disposed on the lower side.

  Next, a modification in which the door of the side panel opens in the left-right direction with the Z direction as the rotation axis will be described. In FIG. 25 (a), a hinge 105 for partially opening the front panel 150 is provided along a rotation axis parallel to the Z direction and passing through about half the width of the front panel 150 in the Y direction. It is a figure which shows the heat insulation container 100G. The front panel 150 in this case is divided into a left door portion 154 and a plate portion 153 that is fixed to the right heat insulating container and does not move, and the right end portion of the door portion 154 and the left end portion of the plate portion 153 are divided. The door portion 154 can be opened toward the + X direction on the near side by being rotatably joined by the hinge 105. A metal plate part frame part 410 and a door part frame part 420 are provided at the left end of the plate part 153 and the right end of the door part 154, respectively, and they both follow the rotation axis of the hinge when the door part 154 is closed. Touching.

  Since the right half of the front panel 150 is fixed to the heat insulation container and the heat insulation container 100G is a plate part 153 that does not move, this part always has its own weight or the weight of the heat insulation container even when the left door part 154 is open. Supports loads such as the load of containers stacked in two stages on the top. Further, when the door portion 154 is closed, the metal plate portion frame portion 410 and the door portion frame portion 420 can support the load load in the vertical direction of the panel while being in contact with each other. While improving, the risk of the failure | damage of the vacuum heat insulating material with which the front panel 150 and another panel are provided can be reduced.

  In addition, as illustrated in FIG. 25B, the heat insulating container H in which the width of the door portion 154 in the horizontal direction, that is, the Y direction side is smaller than the width of the plate portion 153 can be used. In this case, the heat insulating container 100H occupies the section of the right half or more of the front panel 150 by the plate part 153 that is fixed to the heat insulating container and does not move, so that even if the left door part 154 is open, the weight of the heat insulating container In addition, the effect of supporting the load such as the load of the container stacked in two stages on the upper stage is high. Further, when the door portion 154 is closed, the effect of supporting the vertical load on the panel while the plate portion frame portion 410 and the door portion frame portion 420 are in contact with each other is the same as that of the above-described heat insulating container 100G. The width of the door 152 of the heat insulating containers 100G and 100H is equal to or less than ½ of the width of the side including the front panel 150 of the heat insulating containers 100G and 100H, which is the sum of the width of the door 152 and the width of the plate 151. By doing, the effect described about the heat insulation containers 100G and 100H can be acquired. Furthermore, with this size, the door can be completely opened 180 degrees even when another insulated container or baggage is placed on the right side of the insulated container without any gaps. can do.

  Or as shown to Fig.26 (a), it can also be set as the heat insulation container I which made the width | variety of the horizontal direction of the door part 154 larger than the width | variety of the board part 153. FIG. In this case, the heat-insulating container 100I has a large area that can be opened by the door 154 on the left side of the front panel 150, thereby improving workability when a large package is taken in and out after the heat-insulating container is assembled.

  Furthermore, as shown in FIG. 26 (b), the lateral width of the door portion 154 may be substantially the entire width of the front panel 150, and the heat insulating container 100J having a structure in which the entire front panel 150 is opened may be used. In this case, the plate portion is not the front panel 150 but the adjacent right panel 120. The door part frame part 420 arranged at the right end of the door part 154 and the plate part frame part 410 which is an end part of the adjacent right surface panel 120 can be connected by a hinge 105. In addition to this, a door part frame part 420 extending in the Z direction is also arranged at the left end of the door part 154 farthest from the rotation center.

  Thereby, when the door part 154 is closed, the door part frame part 420 arrange | positioned at the right-and-left both ends of the door part 154 acts as a pillar of a Z direction side, and improves the rigidity of the whole heat insulation container. The plate part frame part 410 of the right panel 120 adjacent to the door part frame part 420 on the right side of the door part 154 further increases the strength as a column on the Z direction side, and improves the rigidity of the entire heat insulating container.
