The present invention relates to a heat insulating container in which a vacuum heat insulating material is used and which can be assembled and disassembled.

The vacuum heat insulating material has a core material and an outer packaging material, and the core material is arranged inside the bag made of the outer packaging material, and the pressure is maintained in a vacuum state lower than the atmospheric pressure. .. Since the heat convection inside the bag is suppressed, the vacuum heat insulating material can exhibit good heat insulating performance. Since the vacuum heat insulating material has higher heat insulating performance per unit thickness than the general foam heat insulating material, the thickness of the heat insulating material can be reduced while ensuring the desired heat insulating property. 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.

1. 1. Overall of the Insulated Container of the Present Disclosure (a) Insulated Container of the Present Disclosure This disclosure describes a heat insulating container in which a vacuum heat insulating material is used and which can be assembled and disassembled. The heat insulating container can form a heat insulating space surrounded by the side panel, the top panel, and the bottom panel, and is in a disassembled state in which the heat insulating space is not formed from the assembled state in which the heat insulating space is formed. It is possible to change to, and to change from the disassembled state to the assembled state. The side panel of the heat insulating container includes an outer panel and an inner panel arranged on the panel surface on the heat insulating space side of the outer panel. The inner panel includes a heat insulating part including a vacuum heat insulating material.

(B) Demand for Insulated Containers of the Present Disclosure Insulated containers are used, for example, in the field of logistics for the storage and transportation of articles that require cold or heat insulation. In such a heat-insulating container, generally, the inside of the container in which articles can be stored is a heat-insulating space 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 the heat insulating performance, the heat insulating panel is required to have a certain thickness. Therefore, the heat-insulated container has a problem that the volume inside the container is smaller than that of a normal container. Therefore, by configuring the heat insulating container so that it can be assembled and disassembled, the heat insulating container is assembled and used for luggage that requires temperature control, and a normal container is used for luggage that does not require temperature control. The heat insulating container can be disassembled and stored.

However, the larger the heat insulating container, the larger the heat insulating panel required for the heat insulating container, but the large heat insulating panel is heavy and difficult to handle. Therefore, the heat insulating container that can be assembled and disassembled is generally of the order of cm in each dimension. However, as a flat pallet widely used in the logistics field, for example, the T11 type standardized by JIS as a flat pallet for integrated transportation in Japan has a vertical width of 1100 mm, a horizontal width of 1100 mm, and a height of 144 mm. Insulated containers, each dimension on the order of cm, may not be able to accommodate the entire baggage to be transported or / and stored on a flat pallet.

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

The side panel includes an outer panel and an inner panel arranged on the panel surface on the heat insulating space side of the outer panel, and the inner panel includes a heat insulating portion including a vacuum heat insulating material. Since the vacuum heat insulating material has good heat insulating performance even if it is small in thickness, the weight of the side panel can be reduced, the storage volume of the heat insulating container in the assembled state can be increased, and the storage volume of the heat insulating container in the assembled state can be increased by using the vacuum heat insulating material. , The heat insulating container in the disassembled state can be made compact. Further, since the outer panel is arranged as a protective material on the outside of the side panel and the inner panel having the heat insulating portion including the vacuum heat insulating material is arranged on the inside of the outer panel, the force is applied from the outside of the heat insulating container. Even if the vacuum heat insulating material is applied, the vacuum heat insulating material is not easily damaged because it is protected by the protective material.

From the above, the heat insulating container of the present disclosure is a heat insulating container in which the vacuum heat insulating material is used and can be assembled and disassembled, and the vacuum heat insulating material can be prevented from being damaged.

(D) Ancillary Structure of Insulated Container The outer panel of the side panel may be provided with a protective material made of an organic polymer. The weight of the heat insulating container can be reduced. Further, the protective material may be made of plastic cardboard or plate-shaped wood. It is possible to secure a certain level of durability while reducing the weight. In the heat insulating container, the outer panel of the side panel may include a support portion described later and a frame portion described later. When provided with a support portion or a frame portion, the outer panel of the side panel has a portion not provided with the support portion and / and the frame portion, and the portion is provided with a protective material made of an organic polymer. The area occupied by the support portion and / and the frame portion on the panel surface on the heat insulating space side of the outer panel and the protective material occupy the panel surface on the heat insulating space side of the outer panel. The ratio of the area occupied by the support portion and / and the frame portion to the panel surface on the heat insulating space side of the outer panel may be 40% or less with respect to the sum with the area. It is possible to improve the heat insulating performance and reduce the weight of the heat insulating container. This ratio can be 20% or less or 10% or less. On the other hand, this ratio may be 1% or more.

In the heat insulating container, the support portion and / and the frame portion of the outer panel of the side panel may be arranged at the corner portion of the heat insulating container, and the protective material of the outer panel of the side panel may be the protective material. It may be arranged on the surface of the heat insulating container. It is possible to efficiently improve the load capacity of the heat insulating container.

The heat insulating container may include a pallet, and the pallet may be arranged on a panel surface of the bottom panel of the heat insulating container opposite to the heat insulating space. Since the heat insulating container with a pallet can be easily moved by a forklift, a hand lift, or the like, 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. Since each panel constituting the heat insulating container can be assembled based on the position of the bottom panel fixed integrally with the pallet, it is easy to arrange each panel at an appropriate position and obtain good heat insulating performance. Become.

The bottom panel of the insulating container may be separable from the pallet. Since a general-purpose pallet can be used, the usability of the heat insulating container of the present disclosure is improved. Further, when loading and unloading the cargo, for example, a corner of the cargo may accidentally collide with the bottom panel. If the bottom panel has the vacuum heat insulating material, the vacuum heat insulating material may be damaged by the collision, but since only the bottom panel needs to be replaced, the repair becomes easy.

The bottom panel of the heat insulating container may include a heat insulating portion including a vacuum heat insulating material. Since the thickness can be made thinner than when foamed heat insulating material is used, the bottom panel can be made lighter, the storage volume of the heat insulating container in the assembled state can be increased, and the heat insulating container in the disassembled state can be made compact. be able to. Further, in the heat insulating container, a bottom protective material made of an organic polymer may be arranged on the heat insulating space side of the bottom panel. The bottom panel having the vacuum heat insulating material can reduce the risk of the vacuum heat insulating material being damaged. Further, since a protective material using an organic polymer material having a relatively low heat transfer property is used, the heat insulating performance is unlikely to deteriorate. Further, the bottom surface protective material may be made of plastic cardboard or plate-shaped wood.

The side panel of the heat insulating container may be provided with a protruding portion toward the bottom panel side in the assembled state at the end portion on the bottom panel side. Since the heat insulating container can be assembled with reference to the position of the protruding portion of the side panel, it becomes easy to arrange each panel at an appropriate position and obtain good heat insulating performance. 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 has a length of at least one set of two opposing sides of 0.5 m or more when the heat insulating container in the assembled state is viewed from the top surface side. It may be a quadrilateral, or it may be a quadrilateral having at least one set of two opposing sides having a length of 1 m or more. Such an outer shape allows the entire load to be transported or / and stored on a flat pallet to be stored. Further, in the heat insulating container, the outer peripheral shape of the side panel of the heat insulating container has a length of at least one set of two opposing sides of 1.4 m when the heat insulating container in the assembled state is viewed from the top surface side. It may be the following quadrilateral. When storing or transporting a heat insulating container, the risk of damage to the outer panel due to a collision can be reduced.

The outer peripheral shape and each dimension of the heat insulating container of the present disclosure are not particularly limited. The heat insulating container of the present disclosure may have each dimension on the order of cm, or one or more of each dimension may be 1 m or more. As a specific example of the outer peripheral shape of the side panel of the heat insulating container, when the heat insulating container in the assembled state is viewed from the top surface side, the vertical width and the horizontal width are 1000 mm or more and 1200 mm or less, respectively. A quadrilateral with a width of 1119 mm or more and 1319 mm or less and a width of 916 mm or more and 1116 mm or less, a quadrilateral with a vertical width of 1100 mm or more and 1300 mm or less and a width of 900 mm or more and 1100 mm or less, and a vertical width of 1100 mm or more and 1300 mm or less and a width of 700 mm or more. 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, respectively, can be mentioned. By making the shape of the side panel suitable for the shape of the standard pallet of each country, it is possible to improve the efficiency of transportation and storage. Further, as the outer peripheral shape of the side panel of the heat insulating container, for example, when the heat insulating container in the assembled state is viewed from the top surface side, it is 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. May be. By making the dimensions suitable for the shape of a standard trolley, it is possible to improve the efficiency of transportation and storage.

The heat insulating container may include a wireless communication device that can be arranged on the side panel, and the wireless communication device is arranged between the outer panel of the side panel and the inner panel of the side panel. May be good. The risk of damage to the wireless communication device can be reduced. The wireless communication device is not limited to the RF tag section described later, and any wireless communication device that receives and transmits radio waves can be used. Examples thereof include RFID devices, specified power-saving wireless devices, wireless LAN devices, Bluetooth devices (“Bluetooth” is a registered trademark), mobile phone devices such as 3G lines, and wireless devices that transmit information via LPWA networks such as LoRa. .. Examples of the wireless communication device include those that communicate with an external device by receiving and transmitting radio waves, and those that communicate with an internal device such as a heat insulating container and a detection device installed inside the heat insulating container by receiving and transmitting radio waves.

The heat insulating container may include a panel on which the wireless communication device is arranged and a replacement panel which is replaceable with the panel on which the wireless communication device is arranged and in which the wireless communication device is not arranged. Further, the heat insulating container of the present disclosure can be exchanged with a panel in which a storage portion capable of storing a cooling agent or a heat insulating agent is arranged and a panel in which the storage portion capable of storing a cooling agent or a heat insulating agent is arranged. , It may be provided with a replacement panel in which a storage unit capable of storing an ice pack or a heat insulating agent is not arranged. Since the insulated containers of the present disclosure can be assembled and disassembled, these replacement panels can be utilized. By utilizing these replacement panels, it is possible to improve the efficiency of transportation and storage by the heat insulating container of the present disclosure. The replacement panel may be any of the side panel, the top panel, and the bottom panel, and may be a panel that constitutes a part of these panels.

The heat insulating container may include a conductive material in contact with the heat insulating space. The conductive material can prevent static electricity from accumulating inside the heat insulating container.

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

The heat insulating container may include a foam heat insulating material in the heat insulating portion of the inner panel of the side panel between the end face of the vacuum heat insulating material and the end face of the inner panel. By filling the foam heat insulating material without providing a gap between the end face of the vacuum heat insulating material and the end face of the inner panel, deterioration of the heat insulating performance of the heat insulating container can be suppressed.

In the heat insulating container, the outer panel of the side panel and the inner panel of the side panel may be arranged so as to be separable. If the vacuum heat insulating material on the inner panel is damaged, only the inner panel needs to be replaced, which facilitates repair. Further, the heat insulating container may be configured so that the surface of the vacuum heat insulating material can be visually recognized when the outer panel and the inner panel are separated. Since the surface of the damaged vacuum heat insulating material may be abnormally deformed, it is possible to visually inspect the vacuum heat insulating material without damaging the inner panel and examine whether or not the vacuum heat insulating material is damaged. When the heat insulating sheet described later covers the vacuum heat insulating material, the surface of the vacuum heat insulating material can be visually observed by using the transparent heat insulating sheet. Further, in the heat insulating container, the vacuum heat insulating material may be arranged so as to be separable from the inner panel. If the vacuum heat insulating material on the inner panel is damaged, the damaged vacuum heat insulating material can be easily replaced.

It may be arranged so as to be in contact with the end face, and the end face on the other end side of the inner panel may be arranged so as to be in contact with the panel surface of the inner panel of the other partial panel. Since the internal panel layout structure can withstand the impact from the side in all directions, the heat insulating performance of the heat insulating container is stable.

In the heat insulating container, the side panel may include a first partial panel and a second partial panel arranged on the end side of the first partial panel, with the panel surface of the inner panel of the first partial panel. The end face of the inner panel of the second partial panel may be arranged via an elastic body. The side panel may include a first partial panel and a second partial panel arranged on the edge side of the first partial panel, a panel surface of an inner panel of the first partial panel and the second partial panel. The end face of the inner panel of the inner panel may have an arc-shaped arc surface when viewed in a cross section perpendicular to the panel surface, and the first partial panel and the second partial panel are in an assembled state. , The arc surfaces may be arranged so as to be in contact with each other. The side panel may include a first partial panel and a second partial panel arranged on the edge side of the first partial panel, and the end faces of the first partial panel and the inner panel of the second partial panel may be provided.

In the heat insulating container, the side panel may include a first partial panel and a second partial panel arranged on the end side of the first partial panel, with the end of the inner panel of the first partial panel. The end portion of the inner panel of the second partial panel may be arranged so as to form a fitting structure. Since these arrangement structures improve the bonding between the inner panels, the heat insulating performance of the heat insulating container is improved.

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

In the heat insulating container, the side panel may include a plate portion forming a wall surface and a door portion that can be rotated and opened / closed with respect to the plate portion around a linear rotation center. In the open state, a cushioning material may be arranged between the plate portion and the door portion. Since the plate portion and the door portion do not come into direct contact with each other, the risk that the door portion and the door portion directly collide with each other when the door portion is opened from the closed state and the vacuum heat insulating material is damaged can be reduced. can.

In the heat insulating container, the side panel may include a plate portion forming a wall surface and a door portion that can be rotated and opened / closed with respect to the plate portion around a linear rotation center, and the side panel may be provided at the rotation center. When looking at the cross sections that are orthogonal to each other, the interface between the plate portion and the door portion in the closed state of the door portion does not have to be on the same plane. Heat transfer through the boundary between the plate and door is suppressed, and the heat insulation performance of the heat insulating container is improved. Further, the position where the outer panel on the plate portion side and the outer panel on the door portion side come into contact with each other and the position where the inner panel on the plate portion side and the inner panel on the door portion side come into contact with each other are arranged so as to be offset from each other. The boundary surface does not have to be coplanar, and may be bent, for example. Since the inner panel on the plate side or the inner panel on the door side covers the position where the outer panel on the plate side and the outer panel on the door side come into contact with each other, heat transfer through the boundary between the plate part and the door part is more It can be suppressed. The end surface of the inner panel on the plate portion side and / or the door portion side in the open state of the door portion may have a display portion. Since the display acts as a warning, the risk of damaging the vacuum heat insulating material due to impact on the edge of the inner panel on the plate side or the inner panel on the door side, which is not protected by the outer panel, can be reduced. can.

The side panel or the top panel is connected to a door portion that can be opened and closed, a latch mechanism that holds the door portion in a closed state, and a latch mechanism that releases the holding state of the door portion by the latch mechanism. The door portion may be provided with a deformable handle portion arranged on the door portion so as to cover at least a part of the operating member and the operating member. When assembling or disassembling the heat insulating container, the risk of the operating member accidentally hitting the inner panel and damaging the vacuum heat insulating material can be reduced.

In the heat insulating container, the top panel is separable from the side panel and is foldable. When assembling or disassembling the heat insulating container, the work of raising and lowering the top panel is facilitated, and the risk of the top panel accidentally hitting the internal panel and damaging the vacuum heat insulating material can be reduced.

Among the horizontal planes perpendicular to the + Z direction, the direction from the back panel 140 to the front panel 150, which is perpendicular to the panel surface of the back panel 140, is the + X direction, and the direction opposite to the + X direction is the −X direction. The + X direction and / or the -X direction may be simply referred to as the X direction. The direction from the left panel 130 to the right panel 120, which is perpendicular to the panel surface of the right panel 120 orthogonal to the + X direction, is the + Y direction, and the direction opposite to the + Y direction is 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 than the main surface is the end surface. The panel surface side on the heat insulating space side of each panel is the inside of the panel, and the panel surface side opposite to the panel surface side on the heat insulating space side is the outside of the panel.

The front panel 150 and the top panel 170 have a structure that can be partially opened and closed, and FIG. 1 shows a partially opened state. The heat insulating container 100 of FIG. 1 is in an assembled state of a quadrangular prism structure by closing the front panel 150 and the top panel 170, and is surrounded by the side panel 110, the top panel 170, and the bottom panel 190. It is possible to form a heat insulating space inside the container.

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

As shown in FIG. 2, the front panel 150, the left panel 130, the back panel 140, and the right panel 120, which are the side panels 110, are the outer panels 150B, 130B, 140B, 120B, and the inner panels 150A, 130A, 140A, 120A, respectively. To be equipped. 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 insulation including vacuum heat insulating material. Since the inner panel 190A is protected by the pallet 500, in this example, the bottom panel does not include the outer panel, but the present invention is not limited to this, and the bottom panel may include the outer panel. .. As a result, it is possible to prevent the bottom panel from being pressed against the unevenness of the surface of the pallet 500 by the load of the load and damaging the vacuum heat insulating material contained in the inner panel 190A of the bottom panel. Further, in this example, the top panel 170 includes the outer panel 170B, but the present invention is not limited to this, and the top panel may not include the outer panel 170B.

As shown in FIGS. 1 and 2, the right panel 120, the left panel 130, and the front panel 150 are located at the left and right edges of the panel, respectively, from the top panel side edge, which is the upper side of the panel, to the bottom of the panel. It includes a support portion 310 that extends continuously to the end on the bottom panel side, which is the side. Although not shown, the same applies to the back panel 140. The support portion 310 serves as a pillar or a wall that supports the weight of the panel and the load from the top surface side. Thereby, it is possible to prevent the vacuum heat insulating material from being damaged. However, the existence of the support portion is not limited, and the support portion may not be provided. The support portion may be made of metal. The side panel is provided with a metal support with high load capacity, so even if the heat insulating container is enlarged and it is attempted to be stacked in two layers, there is a risk that the vacuum heat insulating material will be damaged. Can be reduced. When the support part is made of metal, the support part is assembled by the panel surface on the heat insulating space side of the side panel, the panel surface on the heat insulating space side of the top panel, and the panel surface on the heat insulating space side of the bottom panel. By avoiding contact with the heat insulating space formed, it is possible to prevent heat from being transferred through the metal support portion having high heat transfer property and deteriorating the heat insulating performance of the heat insulating container. For example, as shown in FIGS. 1 and 2, by arranging the metal support portion 310 on the outer panel, the metal support portion 310 does not come into contact with the heat insulating space 300, so that deterioration of the heat insulating performance of the heat insulating container is suppressed. can.

As shown in FIGS. 1 and 2, in the assembled state, the heat insulating space 300 of the heat insulating container 100 has an inner panel surface of the side panel 110, an inner panel surface of the top panel 170, and an inner panel surface of the bottom panel 190. Is formed by. The panel surfaces of the side panel 110, the top panel 170, and the bottom panel 190 on the heat insulating space 300 side are composed of the inner panel surfaces of the inner panels 120A, 130A, 140A, 150A, 170A, and 190A having the vacuum heat insulating material, respectively. Has been done.

In the insulation container 100 of FIGS. 1 and 2, the right panel 120, the left panel 130, and the front panel 150 are located on the upper and lower edges of the panel, respectively, from the right edge of the panel to the left edge of the panel. It is provided with a frame portion 320 that extends continuously to. The front panel 150 also includes a frame portion (not shown) that extends continuously from the right edge of the panel to the left edge of the panel near the center of the panel. Further, the top panel 170 includes a frame portion 320 at each of the upper, lower, left, and right ends of the panel, which continuously extends from one end of the panel to the other end. The frame portion is arranged to support the load when the heat insulating container 100 is laterally applied during transportation or storage, and to suppress damage to the vacuum heat insulating material. Further, it can also serve as a cross beam that transmits the load from the top surface side to the support portion 310. Thereby, it is possible to prevent the vacuum heat insulating material from being damaged. However, the existence of the frame portion is not limited, and the frame portion may not be provided. The frame portion may be made of metal. By providing a metal frame with high load capacity, the risk of damage to the vacuum heat insulating material can be reduced even if the heat insulating container is enlarged and it is attempted to be stacked in two layers. can. When the frame part is made of metal, the frame part is assembled by the panel surface on the heat insulating space side of the side panel, the panel surface on the heat insulating space side of the top panel, and the panel surface on the heat insulating space side of the bottom panel. By not contacting the formed heat insulating space, it is possible to prevent the heat from being transferred through the metal frame portion having high heat transfer property, and the heat insulating performance of the heat insulating container from being deteriorated. For example, as shown in FIGS. 1 and 2, by arranging the metal frame portion 320 on the outer panel, the metal frame portion 320 does not come into contact with the heat insulating space 300, so that deterioration of the heat insulating performance of the heat insulating container is suppressed. can.

FIG. 3 shows the heat insulating container 100 in the assembled state of this example. The heat insulating container assembly work can be performed by, for example, the following procedure. The pallet 500 is placed on the floor of the work place with the side on which the luggage is placed facing up. The bottom panel 190 of the heat insulating container 100 is arranged on the surface of the pallet 500 on which the luggage is placed. Place your luggage on the bottom panel. Assemble the disassembled heat insulating container 100 so that the luggage can be stored inside the container. As a result, it is possible to obtain an assembled heat insulating container 100 in which the luggage placed on the pallet 500 is stored inside. The assembly work of the heat insulating container 100 in the disassembled state may be started before the luggage is deposited on the bottom panel, and the luggage may be stored inside the container after or / or during the assembly.

The heat insulating container 100 is, for example, a container used for storing or transporting articles that need to be kept cold or warm, such as frozen products and heated products. As shown in FIG. 4, the heat insulating container 100 has a substantially rectangular parallelepiped shape and includes a transport pallet 500. A claw hole 501 penetrating the opposite side surface is provided on the side surface of the pallet 500. By inserting the claw portion of the forklift into the claw hole 501, the heat insulating container 100 in which the article is stored can be moved together with the pallet 500.

As shown in FIG. 4, the heat insulating container 100 has a substantially rectangular parallelepiped shape surrounded by a pallet 500, a bottom panel 190, a front panel 150, a left surface panel 130, a back panel 140, a right surface panel 120, and a top panel 170. The front panel 150 faces the back panel 140 with the panel surface parallel to each other, and the panel surfaces are 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 with the panel surface parallel to each other, and the panel surfaces are adjacent to the top panel 170, the bottom panel 190, the back panel 140, and the front panel 150 in a vertical positional relationship. .. Further, 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 has four sides having a vertical width and a horizontal width of 1000 mm or more and 1200 mm or less, respectively, when the heat insulating container 100 in the assembled state is viewed from the top surface side, that is, from the + Z direction. It is a shape. It is advantageous not only to increase the storage capacity in one heat insulating container, but also to make the length of one side as long as possible, as well as the loading platform, container, warehouse, etc. of transportation machinery such as trucks, railroads, ships, and aircraft. It is also efficient for efficiently storing in a limited space. The length of one side of the side panel of the heat insulating container is preferably approximated to the dimensions 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 is 1100 mm in length and width.

The front panel 150 is a panel that can be partially opened and closed by the hinge 101. Support portions 310 extending in the direction parallel to the Z direction are arranged at the ends of the front panel 150 in the + Y direction and the −Y direction. A frame portion 320 extending in a direction parallel to the Y direction is arranged at the end portions of the front panel 150 in the + Z direction and the −Z direction.

As shown in FIG. 5, the top panel 170 has an outer panel 170B and an inner panel 170A. The front panel 150, the left panel 130, the back panel 140, and the 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 composed of only the inner panel 190A. Each panel is arranged so that its inner panel faces the inner enclosed space side. The area surrounded by the panel surface inside the inner panel is the heat insulating space 300.

(B) Assembling and disassembling the heat insulating container (i) Assembling the heat insulating box FIGS. 6 to 10 are diagrams for explaining an example of each assembling process when the heat insulating container 100 is assembled in order. First, as shown in FIG. 6, the bottom panel 190 is laid on the pallet 500. Next, the left side 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 arranged on the + Y direction side, which is the heat insulating space 300 side.

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

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

Next, as shown in FIG. 9, the front panel 150 is arranged upright on the + X direction side of the bottom panel 190. A side guide portion 352 facing the pallet 500 is provided at the lower end of each of the left panel 130, the back panel 140, the right panel 120, and the front panel 150, and the side guide portion 352 is 4 of the pallet 500. Adjacent to the side. As a result, even if the side panel 110 receives a horizontal force from the outside, the panel is prevented from being displaced and slipping off the pallet 500. The inner panel 150A of the front panel 150 is arranged on the −X direction side, which is the heat insulating space 300 side.

Finally, as shown in FIG. 10, the top panel 170 is placed above the four side panels 110, that is, on the + Z direction side, and the assembly of the heat insulating container 100 is completed. The top panel 170 only covers the four side panels 110 by its own weight, but since the top guide portion 351 facing the side panel side is attached to the end, it is extremely even if it receives vibration during transportation. It is possible to prevent the mounting position from shifting. In order to suppress the deviation, the side panels 110 may be additionally connected by screws or the like used for joining the side panels 110, or may be joined by a hook-and-loop fastener or the like.

In the above description of the assembly method, the side panel 110 is assembled in the order of the left side panel 130, the back panel 140, the right side panel 120, and the front panel 150. It is also possible to assemble the right side panel 120, the back panel 140, the left side panel 130, and the front panel 150 in this order, and it is also possible to assemble in the order of the front panel 150, the left side panel 130, the back panel 140, and the right side panel 120. be.

(Ii) Disassembly of the heat insulating box The disassembly method can be basically performed in the reverse order of the assembly method. First, the reverse work of FIG. 10 will be started, but the top panel 170 is removed, then the front panel 150 is removed as the reverse work of FIG. 9, and then the right panel 120 is removed as the reverse work of FIG. .. Further, as the reverse work of FIG. 7, the back panel 140 is removed, and finally, as the reverse work of FIG. 6, the left side panel 130 and the bottom panel 190 are removed to complete the disassembly work.

As described above, when it is not used as a heat insulating container in which an article is put in a heat insulating space, it is effective to store and transport the product with the entire volume as small as possible.

11 (a) to 11 (c) are views of the disassembled panels stacked in a designated order as viewed from the side.

As shown in FIG. 11A, in a state where the heat insulating container 100 is disassembled, for example, a bottom panel 190 composed of an inner panel 190A is placed, a left surface panel 130 is placed on the bottom panel 190, and the inner panel 130A is on the lower side. The upper side is stacked in the direction of the outer panel 130B, and the back panel 140 is stacked on the back panel 140 in the direction of the outer panel 140B on the lower side and the inner panel 140A on the upper side. The right side panel 120 is stacked on the right side panel 120 so that the lower side is the inner panel 120A and the upper side is the outer panel 120B. The top panels 170 are stacked in a direction of 150A, and finally, the top panel 170 is stacked in a direction in which the lower side is the inner panel 170A and the upper side is the outer panel 170B. Even in the disassembled state, by arranging the bottom panel, the side panel, and the top panel in this order from the lower side to the upper side, it becomes easier for the operator to understand when assembling.

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

As shown in FIG. 11B, it is also effective to provide an order identification display 105 that can clearly identify whether or not the stacking order of the panels is correct by looking at the side surface of the stacked panels. It is possible to manage the order in which the disassembled panels are stacked does not change depending on the proficiency level of the operator and the presence or absence of misunderstanding. In FIG. 11B, the shapes of continuous parallelograms are displayed so that they can be recognized when they are overlapped, but the present invention is not limited to this, and the side surfaces of each panel may be numbered or letters in order. It may be designed so that the correct design can be recognized when stacked correctly, but the correct design cannot be recognized when stacked incorrectly.

As shown in FIG. 11C, an order identification fitting structure in which the fitting convex portion 106a and the fitting concave portion 106b are correctly fitted to each other only when they are correctly overlapped with each other of the outer panels to be stacked so as to face each other. 106 may be provided. Note that FIG. 11 (c) is an enlarged view of part A of FIG. 11 (a). For example, the outer panel 130B of the left panel 130 and the outer panel 140B of the back panel 140 are adjacent to each other, and the outer panel 120B of the right panel 120 and the outer panel 150B of the front panel 150 are adjacent to each other at different positions and sizes. If the fitting structure 106 for order identification by quantity is provided, even if the panels are stacked in the wrong order and combination, some parts cannot be fitted, so that the operator can easily recognize the mistake. can.

(C) Side Panel (i) Structure Among the panels constituting the heat insulating container 100, the side panel 110 will be described. The side panel 110 is composed of four panels, a front panel 150, a left panel 130, a rear panel 140, and a right panel 120, of which the left panel 130, the rear panel 140, and the right panel 120 have the same structure. Therefore, the configurations of the back panel 140 and the front panel 150 will be described in order. 12 (a) and 12 (b) are views of the back panel 140 viewed in a plan view from a direction perpendicular to the panel surface. FIG. 12A is a view of the back panel 140 viewed from the outside of the heat insulating container 100 in the −X direction, and FIG. 12B is a view of the back panel 140 from the inside of the heat insulating container in the + X direction. It is a view.

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

Each dimension of the outer circumference of the inner panel 140A is smaller than each dimension of the outer circumference of the outer panel 140B, and the inner panel 140A is arranged in the panel surface of the outer panel 140B. Since the edge of the inner panel is protected by the edge of the outer panel, it is possible to prevent the vacuum heat insulating material of the inner panel 140A from being damaged. Furthermore, by making the dimensional difference in consideration of the thickness of the panel, one end of the inner panel of the back panel is brought into close contact with the end of the inner panel of the left panel, and the other end is brought into close contact with the end of the inner panel of the right panel. When the edges of the outer panel of each panel are brought into close contact with each other, the edges of the outer panels of each panel can be similarly brought into close contact with each other, and the heat insulating property of the heat insulating space can be improved in the heat insulating container in the assembled state.

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

FIG. 13A is a cross-sectional view showing an example of the structure of the heat insulating portion 330. The heat insulating portion 330 is composed of the vacuum heat insulating material 331, the foam heat insulating material 332 that surrounds both one and the end faces of the main surface of the vacuum heat insulating material 331, and the heat insulating sheet 333 that encloses the entire outer periphery thereof. Since the foam heat insulating material 332 is arranged on both sides of the end face of the vacuum heat insulating material 331, the heat insulating performance is compared with the case where the foam heat insulating material 332 is not arranged on both sides of the end face of the vacuum heat insulating material 331 and is a space. Is improved. The vacuum heat insulating material 331 is composed of a core material 331a and an exterior material 331b. Since the vacuum heat insulating material 331 cannot maintain the vacuum when the exterior material 331b is damaged and cannot obtain the desired heat insulating property, the vacuum heat insulating material 331 is the foam heat insulating material 332 on the heat insulating space side. Is placed. This makes it possible to reduce the risk of damaging the vacuum heat insulating material 331 when the articles placed in the heat insulating space collide with each other. In the configuration of FIG. 13A, the vacuum heat insulating material 331 is protected by an outer panel arranged on the side opposite to the heat insulating space. Although not shown, a protective base material described later may be arranged on the side opposite to the heat insulating space of the vacuum heat insulating material 331.

When forming the heat insulating portion 330 shown in FIG. 13A, it is not always necessary to integrally mold the foam heat insulating material 332 by injection molding after setting the vacuum heat insulating material 331 in the mold, and the heat insulating material 332 is manufactured separately from each other. It is also permissible to join the material afterwards with an adhesive or the like. Further, since the amount of the foamed heat insulating material used can be reduced, the thickness of the heat insulating portion itself can be reduced, and the accommodation volume can be increased. Further, there is flexibility in the manufacturing method such as separately preparing the vacuum heat insulating material 331 and the foam heat insulating material 332, and it is easy to replace only the vacuum heat insulating material, so that maintainability is improved. The vacuum heat insulating material 331 and the foam heat insulating material 332 may be fixed by 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 weakly adhesive adhesive.

FIG. 13B is a cross-sectional view showing another example of the structure of the heat insulating portion 330. The heat insulating portion 330 is composed of the vacuum heat insulating material 331, the foamed heat insulating material 332 surrounding the vacuum heat insulating material 331, and the protective base material 338 surrounding the foamed heat insulating material 332. Further, the heat insulating sheet 333 is a protecting group of the heat insulating portion 330. Surrounds the material 338. As the protective base material, for example, a protective material made of an organic polymer for the outer panel, which will be described later, can be used. Although not shown, the structure of the heat insulating portion 330 includes the vacuum heat insulating material 331, the foamed heat insulating material 332 surrounding the vacuum heat insulating material 331, the heat insulating sheet 333 surrounding the foamed heat insulating material 332, and the protective base material 338 surrounding the heat insulating sheet. It may be composed of. As the protective base material at this time, for example, a protective material made of an organic polymer for the outer panel, which will be described later, can be used.

As shown in FIG. 14A, the vacuum heat insulating material 331 is composed of a core material 331a and an exterior material 331b having a gas barrier property, and is a heat insulating material obtained by reducing the pressure inside the exterior material 331b. FIG. 14B is another example of the vacuum heat insulating material 331. In FIG. 14 (a), voids are formed at both ends inside the vacuum heat insulating material 331, but in FIG. 14 (b), voids are not formed. The voids may or may not be formed due to the difference in the manufacturing method of the vacuum heat insulating material 331.

As the core material 331a, a material used for the core material of a known vacuum heat insulating material that has been conventionally used can be used. For example, a powder such as silica, a foam such as urethane polymer, a fiber body such as glass wool, etc. You may use the porous body of.

The exterior material 331b is a member that covers the outer periphery of the core material 331a, and a flexible sheet in which a core material, a heat welding layer, and a gas barrier layer are laminated in this order may be used. As the gas barrier layer, a metal foil, a thin-film deposition sheet in which a thin-film deposition layer is formed on one side of a resin sheet, or the like may be used. As the metal foil, for example, aluminum can be used. 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, for example, 5 Pa or less. The initial thermal conductivity of the vacuum heat insulating material 331 is, for example, 15 mW ・ m ^-1・ K ^-1 or less in an environment of 25 ° C., especially 10 mW ・ m ^-1・ K ^-1 or less, especially 5 mW ・ m ^-1・ K ^-1. It may be as follows.

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

The heat shield sheet 333 can be arranged so as to cover the entire adjacent vacuum heat insulating material 331 and the foam heat insulating material 332. Examples of the heat shield sheet 333 include a multilayer sheet containing a metal foil, a thin-film sheet in which a thin-film layer is formed on one side of a resin sheet, and the like.

The heat insulating portion 330 can be configured so that the vacuum heat insulating material 331 can be visually recognized from the outside. For example, a region where the foamed heat insulating material 332, the heat shield sheet 333, and the protective base material 338 do not exist may be provided, and a part or all of them may be made transparent. When the vacuum heat insulating material 331 is damaged and abnormal deformation occurs on the surface, the damaged state of the vacuum heat insulating material can be confirmed without damaging the inner panel.

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

The structure of the adjacent portion between the back panel 140 and the left panel 130 will be described. 15 (a) and 15 (b) are a plan view and a cross-sectional view of an adjacent portion between the back panel 140 and the left panel 130. FIG. 15A is a plan view of the heat insulating container 100 as seen from the + Z direction when the top panel 170 is removed. FIG. 15B is an enlarged view of the vicinity of the portion B of FIG. 15A at the portion of the screw connecting portion 341 that connects the adjacent portions of the back panel 140 and the left side panel 130, cut in a cross section perpendicular to the Z direction. It is a cross-sectional view.

As shown in FIG. 15A, the side panel 110 is arranged 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 are in contact with each other, and the inner panel 130A of the left panel 130 is in contact with each other. Is arranged so that the end surface of the back panel 140 and the panel surface of the inner panel 140A of the back panel 140 are in contact with each other, and the end surface of the inner panel 140A of the back panel 140 and the panel surface of the inner panel 120A of the right side panel 120 are arranged so as to be in contact with each other. , The end surface of the inner panel of the right side panel 120 and the panel surface of the inner panel 150A of the front panel 150 are arranged so as to be in contact with each other. In this way, the inner panel of each side panel 110 is in contact with two adjacent side panels at two locations, an end surface and a panel surface. As a result, each panel of the side panel 110 can have the same dimensions, arrangement, and structure of the outer panel and the inner panel when the opening / closing portion is not provided, and the panel parts can be standardized. As a result, the stock of spare parts such as the outer and inner panels, the heat insulating part, and the vacuum heat insulating material can be reduced, and the parts replacement and repair work can be facilitated. Further, in the assembling work, for example, even if the left side panel 130, the back side panel 140, and the right side panel 120 are misaligned with each other, they can be assembled without any problem, and there is no functional problem, and workability and convenience are improved. can. The arrangement of each panel is not limited to FIG. 15A, and there are modifications described later, for example.

The support portion 310 will be described. As shown in FIG. 15B, as the configuration of the left panel 130, the heat insulating portion 330 composed of the heat insulating sheet 333, the foam heat insulating material 332, and the vacuum heat insulating material 331 is formed from the + Y direction side to the −Y direction side. be. On the −Y direction side, there is a protective material 322 sandwiching the adhesive 334, 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 tip of the protective material 322 in the −X direction with a groove portion 310c interposed therebetween. The protective material 322 and the partial support portion 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 composed of a heat insulating sheet 333, a foam heat insulating material 332, and a vacuum heat insulating material 331 from the + X direction side to the −X direction side. There is a protective material 322 sandwiching the adhesive 334 on the −X direction side, and the adhesive 334 adheres and fixes the heat insulating portion 330 and the protective material 322. The internal structure of the heat insulating portion 330 of the back panel 140 is the same as that of the heat insulating portion 330 of the left side panel 130 described above. A partial support portion 310b, which is a constituent member of the support portion 310, is fitted and fixed to the tip of the protective material 322 in the −Y direction with a groove portion 310c interposed therebetween. A through hole is formed in a part of the partial support portion 310b and the above-mentioned partial support portion 310a, and the partial support portion 310b is connected by a screw connecting portion 341.

In FIG. 15B, the end surface 330a of the heat insulating portion 330, which is the end surface of the inner panel 130A of the left side panel 130 on the −X direction side, is the surface of the heat insulating portion 330, which is the inner panel surface of the inner panel 140A of the back panel 140. It is in contact with 330b and maintains the heat insulating property of the heat insulating space surrounded by the heat insulating portion 330. Further, the partial support portion 310a of the left surface panel 130 and the partial support portion 310b of the back panel 140 are in contact with each other to form an integral support portion 310, and the support portion 310 is in a direction perpendicular to the panel surface of the bottom panel 190. In addition, it extends continuously from the end on the top panel 170 side to the end on the bottom panel 190 side to the end on the top panel 170 side. Since the two partial support portions 310a and 310b are connected by the screw joint portion 341, the left side panel 130 and the back panel 140 can be fixed without being displaced from each other and the required rigidity can be obtained. ..

Various materials such as metal materials, organic polymer materials, ceramics, and carbon fibers, and composite materials thereof can be applied to the support portion 310. As for the metal material, for example, iron, stainless steel, aluminum, aluminum alloy, copper, brass, zinc and the like can be used. As for the organic polymer material, for example, acrylonitrile-butadiene-styrene (ABS), polycarbonate, fiber reinforced plastic (FRP) and the like can be used.

When the support part is made of a metal material, the side panel is provided with a metal support part having a high load-bearing capacity, so that the heat insulating container is enlarged and the vacuum is vacuumed even when the heat insulating container is to be stacked in two stages. The risk of damage to the heat insulating material can be reduced. When the support part is made of metal, by preventing the support part from coming into contact with the heat insulating space in the assembled state, heat is transferred through the metal support part having high heat transfer property, and the heat insulating performance of the heat insulating container is deteriorated. Can be suppressed. In addition, when the support part is made of an organic polymer material, it is easy to select a material that is relatively lightweight and has low thermal conductivity. Therefore, the weight of the entire heat insulating container can be reduced and the degree of freedom in the structural surface of the support part can be increased. Can be expanded. For example, even if the support portion has a structure in contact with the heat insulating space, the influence on the deterioration of the heat insulating performance of the heat insulating container can be reduced as compared with the case where the support portion is made of a metal material.

The protective material 322 will be described. When used in the components of the outer panel, the protective material 322 protects the vacuum heat insulating material 331 of the inner panel, and the support portion 310 and the frame portion 320 are arranged at the ends thereof to form the outer panel as a whole. It can have rigidity as a surface. The protective material 322 may be made of a material having a low thermal conductivity in order to enhance the heat insulating property. For example, organic polymer materials such as plywood, foaming material, resin plate, embossed resin sheet, and paperboard, and ceramic members can be used. As a lightweight and relatively rigid material, plastic cardboard, cured wood, or the like can be used. The protective material 322 is joined to the heat insulating portion 330 adjacent to the inside, that is, the heat insulating space side, via the adhesive 334. As the adhesive 334, any liquid or solid adhesive can be used. Since the heat insulating portion can be easily attached and detached, for example, a hook-and-loop fastener or double-sided tape may be used. By making it removable, 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 maintainability is improved.

The frame portion 320 will be described. As described with reference to FIGS. 12 (a) and 12 (b), the frame portion 320 extends from the right end of the outer panel to the left end of the outer panel at the upper and lower ends of the outer panel, respectively. It is arranged so as to extend continuously. In the present embodiment, the material of the frame portion 320 is designed and the structure is simplified by using the same member as the support portion 310, but the material does not necessarily have to be the same.

The outer panel 140B of the back panel 140 may include a side guide portion 352, which is a protruding portion toward the pallet 500, in order to prevent the back panel 140, which will be described later, from slipping off the pallet 500.

(Iii) Left panel, right panel Since the left panel 130 and the right panel 120 have the same structure as the back panel 140 described above, the description of the left panel and the right panel will be omitted.

The structure is similar to that of other side panels. Further, the height of the outer panel of the openable front panel 150 is lower than the height of the outer panels of the right side panel, the back side panel, and the left side panel. Therefore, in the heat insulating container in the assembled state, the position of the end surface on the top surface side of the front panel is lower than the position of the end surface of the right surface panel, the back panel, and the left surface panel. Therefore, even if the end surface of the side panel is bent due to the weight of the top panel or other heat insulating container, the opening and closing of the front panel is not hindered.

The environmental conditions of the measurement target are, for example, temperature, humidity, pressure, acceleration, position and the like. A known temperature sensor, humidity sensor, pressure sensor, acceleration sensor or vibration sensor, GPS sensor and the like can be used, respectively.

Details of the operation and function of the RF tag 600 with a sensor will be described. First, by non-contact communication between the external device and the RF tag 600 with a sensor, the sensor unit 630 transmits instruction information about the measurement frequency for measuring the environmental state of the heat insulating space from the external device to the RF tag 600 with a sensor. The sensor unit 630 is assumed to be a temperature sensor.

The RF tag unit 610 of the RF tag 600 with a sensor acquires instruction information from an external device through the communication antenna unit 611 and the communication interface unit 612, decodes it by the control unit 613, and records it at predetermined time intervals according to the measurement frequency information. , A measurement instruction is transmitted to the sensor unit 630.

It is transmitted to the control unit 613.

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

By the way, if the sensor unit 630 and the RF tag unit 610 are brought close to each other and installed inside the inner panel 130A, the length of the cable unit 620 can be shortened, and the trouble of providing a through hole in the outer panel can be saved. However, as the heat shield sheet 333 that covers the outer periphery of the heat insulating portion 330 of the inner panel 130A and the exterior material 331b of the vacuum heat insulating material 331, a thin film sheet or the like in which a thin film layer is formed on one side of a metal foil or a resin sheet is used. Since there are many metal members and many metal members, it is considered that the wireless communication function between the RF tag unit 610 and the external device may be hindered, and there is a risk that the communication distance and the communication stability may be lowered. Further, the vacuum heat insulating material 331 may be arranged in the immediate vicinity of the inner panel surface of the inner panel 130A, and when both the sensor unit 630 and the RF tag unit 610 are attached to the panel surface, the vacuum heat insulating material 331 may be arranged. The vacuum heat insulating material 331 may be damaged by the load.

Therefore, as in the present embodiment, by separating the RF tag unit 610 from the sensor unit 630 and attaching it to the outside of the outer panel 130B, wireless communication with the external device is not hindered and a good communication distance is obtained. And communication stability can be obtained, and the load on the vacuum heat insulating material due to installation can be reduced, and the risk of damage to the vacuum heat insulating material can be reduced.

Further, as shown in FIGS. 22 (a) and 22 (b), the cable portion 620 is not wrapped around to the end of the inner panel 130A, but a through hole 330c is opened in the panel surface of the inner panel 130A and pulled out to the outside of the inner panel. You can also. However, in this case, it is necessary to select the location and the hole diameter of the through hole so as to avoid the arrangement of the vacuum heat insulating material 331 in the heat insulating portion 330. Further, in this figure, the RF tag portion 610 is arranged not in the outer side of the outer panel 130B but in the gap portion with the inner inner panel 130A. By doing so, it becomes difficult to attach / detach the RF tag portion 610 from the heat insulating container 100, but it is possible to reduce the risk of damage to the RF tag portion 610 due to an external force during storage or transportation. Further, even in this case, as described above, as compared with attaching the RF tag to the inner surface of the inner panel 130A, it is similarly advantageous in communication with an external device and reduction of the load on the vacuum heat insulating material.

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

Further, the small electronic device including the RF tag 600 with a sensor may be attached to the pallet 500 in whole or in part, or may be arranged at any place on the upper surface, the lower surface, the side surface and the inside of the pallet 500. .. For example, it may be arranged near the central portion of the side surface of the pallet 500 on the horizontal direction side, and further, it may be arranged near the central portion of each of the two adjacent side surfaces in the horizontal direction. Further, a pallet to which all or a part of the small electronic device including the RF tag 600 with a sensor is attached and a pallet to which the pallet is not attached may be used properly, and a pallet may be selected according to the necessity.

Further, depending on the application and the required contents of the heat insulating container 100, the side panel is replaced with a spare panel depending on whether the side panel on which the RF tag portion 610 of the RF tag 600 with a sensor is arranged is used or not. You may use it properly depending on the operation. For example, as the left side panel 130, two panels, one in which the RF tag portion 610 of the RF tag 600 with a sensor is arranged and the other in which the RF tag portion 610 is not arranged are held, and wireless communication of the RF tag 600 with a sensor is required. If this is the case, the heat insulating container 100 can be assembled using the left panel 130 on which the RF tag portion 610 is arranged, and the left panel 130 on which the RF tag portion 610 is not arranged can be stored as a spare panel. .. On the contrary, when the wireless communication of the RF tag 600 with the sensor is not required, the heat insulating container 100 is assembled using the left side panel 130 in which the RF tag part 610 is not arranged, and the left side panel in which the RF tag part 610 is arranged is assembled. The 130 may be stored as a spare panel. This applies not only to the left panel 130 and other side panels 110, but also to the top panel 170 and the bottom panel 190.

As described above, the heat insulating container 100 to which the RF tag 600 with a sensor is attached can measure a desired environmental state such as the temperature of the heat insulating space, and the measured data can be read out from an external device by wireless communication as needed. Is. As a result, it becomes possible to grasp the temperature history of the heat-insulated space, that is, the environmental conditions such as the temperature history of the article, and it is possible to easily obtain important information in guaranteeing the article without opening the heat-insulated container.

Further, by attaching the RF tag portion 610 to the outside of the outer panel 130B, deterioration of the communication function due to the metal member existing in a wide area near the inner panel 130A can be suppressed, and good communication distance and communication stability can be obtained. Can be done.

(J) Conductive Material A form in which a conductive sheet 701 for reducing the accumulation of static electricity is attached to a heat insulating container 100 will be described. 24 (a), 24 (b), and 25 are views showing a state in which the conductive sheet 701 is attached to the heat insulating container 100 of the present embodiment. FIG. 24A is an explanatory view of the bottom panel 190 of the heat insulating container 100 having the conductive sheet 701 on the inner panel surface, and the front panel 150 and the top panel 170 are omitted. .. FIG. 24 (b) is an enlarged cross-sectional view of FIG. 24 (a) cut in a 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. 24A and 24B, the heat insulating container 100 includes a conductive sheet 701 having conductivity on the upper panel surface of the bottom panel 190, and further, a ground connection portion 731 outside the heat insulating container 100. The two are electrically connected by a cable portion 720. The cable portion 720 is arranged on the inner panel surface of the bottom panel 190, and is pulled out through the through hole 322c of the protective material 322 of the outer panel 130B through the gap between the left side panel 130 and the adjacent portion of the back panel 140. , It is connected to the ground connection unit 731.

The conductive sheet 701 is not particularly limited as long as it is a highly conductive member, and is vapor-deposited in which a vapor-deposited layer is formed on one side of a multi-layer sheet or a resin sheet containing a metal such as stainless steel, copper, or aluminum, or a metal foil. It may be a sheet or the like, or a non-metal highly conductive member such as a graphite sheet. The conductive material that can be used in the present embodiment is not limited to the sheet-shaped conductive sheet, and may be, for example, a linear or lump-shaped material. In the case of a sheet-shaped conductive sheet, for example, by arranging it on the inner panel surface of the bottom panel 190, the bottom panel 190 can be protected, and if the bottom panel contains a vacuum heat insulating material, the bottom panel 190 can be protected. , This can be made hard to break.

When an article is placed inside the heat insulating container 100 of FIGS. 24 (a) and 24 (b), the article conducts with the conductive sheet 701 laid on the upper part of the bottom panel 190, and the cable portion electrically connected to the conductive sheet 701. It conducts with the ground connection portion 731 outside the heat insulating container 100 via the 720. Therefore, if the grounding connection portion 731 is electrically connected to the grounding place of the storage place or the transportation equipment, that is, the part where the grounding can be taken, the static electricity carried on the article or the heat insulating container 100 itself can be safely released to the outside. .. Therefore, even when a flammable article is stored or there is a flammable substance in the vicinity of the heat insulating container 100, the risk of ignition accident or the like due to static electricity discharge or the like can be reduced. The ground connection portion 731 may be a metal piece or a conductive member, and may have a shape such as a clip that can be sandwiched and fixed in an external groundable place.

FIG. 25 is a diagram showing 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. A conductive sheet 701 is attached to the pallet, and a conductive mat 732 is laid on the lower surface of the pallet 500, and the two are electrically connected by a cable portion 720. Although the front panel 150 and the top panel 170 are omitted in FIG. 25, in reality, the conductive sheet 701 also exists in these panels.

By attaching the conductive sheet 701 to a wide area covering the heat insulating space as shown in FIG. 25, it is possible to enhance the effect of more safely releasing the static electricity carried by the article or the heat insulating container 100 itself to the outside. Further, when the article is put into the heat insulating container, even if the article hits the inner panel forming the heat insulating space, the conductive sheet 701 attached to the inner panel surface of the inner panel plays a role of absorbing the impact. If the inner panel contains a vacuum heat insulating material, it has the effect of making it difficult to break. Further, by laying the conductive mat 732 on the lower surface of the pallet 500 and integrating it with the pallet 500, even if the grounding is forgotten, the conductive mat 732 laid on the lower surface of the pallet 500 can be used. The effect of discharging to the outside and the atmosphere that comes into contact with nature can be expected. That is, there is an effect of reducing the risk of a fire accident due to electrostatic discharge when the stored article is flammable or when there is a flammable substance in the vicinity of the heat insulating container 100. As the conductive mat 732, a metal such as aluminum, gold, or zinc is deposited on a resin sheet on the surface, or a hydrophilic polymer material is mixed with acrylonitrile, butadiene, styrene (ABS), polystyrene, acrylic resin, or the like. Various types such as a polymer alloy type and a mixture of carbon black and a polymer material can be used.

3. 3. Second Embodiment (a) Structure of Insulated Container A second embodiment will be described. FIG. 26 is a diagram illustrating a heat insulating container 100B according to a second embodiment of the present invention. FIG. 27 is a diagram showing a state in which all the doors are opened in the heat insulating container 100B which is the second embodiment. FIG. 28 is a view of the front panel viewed from the inside in the −X direction.

The main points different from the first embodiment are that the top panel 170 is foldable and that the front panel 150 has a front plate portion in a closed state of the front door portion 161 in a cross section orthogonal to the rotation center axis m. The boundary surface between 151 and the front door portion 161 is not on the same plane.

(B) Deformation Example of Top Panel As shown in FIG. 26, the top panel 170 is divided into two by a straight line n parallel to the Y direction, and has a first upper plate portion 171 and a second upper plate portion 181. ing. The first upper plate portion 171 and the second upper plate portion 181 are rotatably fixed to each other around the straight line n-axis via a hinge 102 arranged on the straight line n.

As shown in FIG. 27, with the first upper plate portion 171 held by the side panel 110, the second upper plate portion 181 is rotated to the + Z direction side around the straight line n-axis to open, or is rotated to the original position. Close Opening and closing operation is possible. Alternatively, although not shown, the first upper plate portion 171 can be opened and closed while the second upper plate portion 181 is held by the side panel 110. Even after assembling the heat insulating container 100, the second upper plate portion 181 or the first upper plate portion 171 can be opened to take in and out articles. 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 surface side.

Further, when disassembling the heat insulating container 100B, the top panel can be removed from the side panel after the top panel is folded as shown in FIG. 27. Further, when assembling the heat insulating container 100B, the side panel can be opened after the top panel in the folded state is placed on the side panel as shown in FIG. 27. Since the top panel can be raised and lowered while the top panel is folded, work efficiency and safety can be improved.

(C) Modification example of front panel As shown in FIG. 26, the front panel 150 is divided into two in a straight line m parallel to the Y direction, and is separated from the front plate portion 151 which is a fixed portion which does not open and close on the −Z direction side. Around the axis of the straight line m, there is a front door portion 161 on the + Z direction side that can be opened and closed by rotating to the + X direction side with respect to the front plate portion 151 or rotating to the original position to close. doing. The front door portion 161 is attached to the front plate portion 151 via a hinge 101 arranged on a straight line m, and the front door portion 161 opens and closes with respect to the front plate portion 151 around a straight line m axis. It is rotatably fixed so that it can be rotated.

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

The configuration of the front panel 150 will be described. FIG. 28 is a view of the front panel 150 as viewed from the inside. When the front panel 150 is viewed from the inside, the inner panel 161A is visible on the + Z direction side, and the inner panel 151A is visible on the −Z direction side. On the outside of the outer periphery of the inner panels 161A and 151A, a support portion 310 and a frame portion 320 arranged at the ends of the outer panels 161B and 151B (not shown) are visually recognized.

The arrangement of the inner panels 151A and 161A in the Z direction is such that the boundary surface between the two is shifted in the + Z direction from the straight line m which is the rotation center axis of the front door portion 161. As a result, when the front door portion 161 is opened, a plurality of step-like steps are formed at the end portions of the front plate portion 151 and the front door portion 161 in the vicinity of the adjacent portions.

FIG. 29 is a cross-sectional view cut at the position of arrows EE shown in FIG. 26. The front plate portion 151 is joined to the heat insulating sheet 333, the foam heat insulating material 332, the heat insulating portion 330 composed of the vacuum heat insulating material 331, and the heat insulating portion 330 in this order from the −X direction via an adhesive 334. The protective material 322, which is a constituent member of the outer panel 151B, is arranged in the front plate portion opening / closing frame portion 321a and the front plate portion opening / closing frame portion 321a with the groove portion 321c interposed therebetween. Further, the front door portion 161 also has the same configuration, and the heat insulating portion 330 and the heat insulating portion composed of the heat insulating sheet 333, the foam heat insulating material 332, and the vacuum heat insulating material 331 are arranged in this order when the front door is viewed from the −X direction. The front door opening / closing frame portion 321b joined to 330 via the adhesive 334, and the protective material 322 which is a constituent member of the outer panel 161B fitted to the front door portion opening / closing frame portion 321b with the groove portion 321c separated from each other are arranged. Has been done. The front plate opening / closing frame portion 321a and the front door opening / closing frame portion 321b are rotatably fixed by hinges 101.

As shown in FIG. 29, the boundary surface between the front plate opening / closing frame portion 321a and the front door opening / closing frame portion 321b, which is the boundary surface between the outer panel 151B of the front plate portion 151 and the outer panel 161B of the front door portion 161 as viewed in cross section. And, since the boundary surface of the heat insulating portion 330, which is the boundary surface between the inner panel 151A of the front plate portion 151 and the inner panel 161A of the front door portion 161 is formed at different positions in the Z direction, the front plate portion The boundary surface between 151 and the front door portion 161 is not on the same plane. As a result, when the front door portion 161 is closed, the inflow of air from the outside is hindered, which has the effect of maintaining the heat insulating property of the heat insulating space. Further, the heat insulating portions are in the vicinity of the boundary surface between the front plate portion opening / closing frame portion 321a and the front door portion opening / closing frame portion 321b, and the boundary surface between the inner panel 151A of the front plate portion 151 and the inner panel 161A of the front door portion 161. Since the vicinity of the boundary surface of 330 is a place where the heat insulating performance is lower than that of other parts, the heat insulating property deteriorated region near the boundary surface between the front plate portion opening / closing frame portion 321a and the front door portion opening / closing frame portion 321b. In addition, by arranging the heat insulating portion 330 including the vacuum heat insulating material 331, there is also an effect of suppressing the heat bridge due to the overlapping of the heat insulating performance deteriorated regions.

FIG. 30 is a view showing a state in which the front door portion 161 is opened in a cross section similar to that in FIG. 29. FIG. 31 is a view showing a state in which the front door portion 161 is opened as an oblique projection drawing based on the cross section of FIG. As shown in both figures, when the front door portion 161 is open, the heights of the ends of the front plate portion 151 and the front door portion 161 near the adjacent portion are sequentially stepwise from the −X direction to the + X direction. Is low, and a warning tape 103 is attached to the stepped end integrally. The material and design of the warning tape 103 are not particularly limited, but the tape 103 may be made of an elastic member such as an elastomer material or a sponge material to enhance the effect of filling the gap and the effect of absorbing the impact of an external force. The presence of the warning tape 103 alerts the user to prevent the fingers from being pinched, and the article collides with the inner panel 161A protruding upward from the outer panel 161B of the front door portion 161 during the loading / unloading operation of the article. The purpose is to call attention to prevent the vacuum heat insulating material of the inner panel 161A from being damaged. Further, the portion to which the warning tape 103 is attached in the present embodiment is the back side when the front door portion 161 is opened from the X direction, that is, the front panel 150, and the heat insulating container 100A is viewed from the side where the article is taken in and out. That is, since the step has a structure in which the step rises as it advances toward the −X direction, the visibility of the warning tape 103 is remarkably improved.

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

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

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

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

As shown in FIGS. 33, 34, 35, and 36, the handle portion 205 is arranged on the front door portion 161 so as to cover the entire operating member 202 when viewed from the + X direction side, that is, the front side from the front panel 150. Has been done. The handle portion 205 is provided at a position corresponding to each of the two operating members 202. In the present embodiment, the handle portion 205 is made of a flexible band-shaped leather, but if it is deformable, it may be a hard material having a link portion or the like, as will be described later. Further, the method of fixing to the front door portion 161 can also be appropriately selected from screw fastening, riveting, adhesive and the like.

The movable rod 201 is attached to the front door portion tip frame portion 162 so as to be movable in the Y direction. The movable rod 201 is urged toward the + Y direction by the spring 203, has a locking shape (not shown), and is predetermined by engaging with a positioning shape (not shown) provided inside the front door portion tip frame portion 162. It is stopped at the position. In the engaged state, the tip portion 201a of the movable rod 201 protrudes from the front door portion tip frame portion 162 in the + Y direction by a predetermined amount, as shown in FIG. 33. When the front door portion tip frame portion 162 is provided with the fitting end portion 162b and the right side panel door receiving frame 122 at the corresponding position is provided with the fitting end portion 122b and the front door portion 161 is closed. In addition, the fitting end portion 122b has a structure for receiving the fitting end portion 162b. When the front door portion 161 is closed, the slope of the tip portion 201a of the movable rod 201 abuts on the fitting end portion 122b and receives a force in the −Y direction, so that the movable rod 201 compresses the spring 203 in the compression direction. Move to the -Y direction while pressing. When the tip portion 201a reaches the fitting hole 122a opened in the fitting end portion 122b, the tip portion 201a can be fitted with the fitting hole 122a and the front door portion 161 can be held in a closed state. When opening the front door portion 161, the operator operates the operating member 202 to move the movable rod 201 toward the −Y direction, thereby pushing the spring 203 in the compression direction and pushing the tip portion 201a to the tip of the front door portion. Immerse yourself in the frame portion 162. After that, the front door portion 161 can be opened by pulling it toward the + X direction.

The handle portion 205 usually has its central portion at a position (first position) shown in FIGS. 35 and 36, which can be grasped by an operator during the opening / closing operation of the front door portion 161. Further, FIG. 37 is a diagram showing a state in which the central portion of the handle portion 205 is in a second position closer to the operating member 202 than in the first position. For example, when an external force such as an impact is applied to the vicinity of the operating member 202 of the heat insulating container 100C from the outside, the handle portion 205 is deformed, and the central portion of the handle portion 205 is located at a position closer to that of the first position as shown in FIG. 37. It can be moved to a second position close to the operating member 202. As a result, it is possible to prevent the handle portion 205 from being deformed and parrying the external force and directly concentrating the external force on the operating member 202, so that the operating member 202 can be protected.

By having the handle portion 205 in the normal first position as shown in FIGS. 35 and 36, the operator can grasp the front door portion 161 during the opening / closing operation, and the operating member 202 is used as the urging force of the spring 203. While operating against it, the operation of pulling down the front door portion 161 toward the + X direction can be easily performed. Therefore, the operability of the operator can be improved.

FIG. 38 is a view of the handle portion 215 having a link portion having a different shape from the handle portion 205 as viewed from above. The handle portion 215 has a grip portion 215a, a first link portion 215b, and a second. The two link portions 215c are provided, and one first link portion 215b and one second link portion 215c are arranged on both sides of the grip portion 215a. In FIG. 38, the first link portion 215b and the second link portion 215c in the front door portion 161 are also shown by solid lines for easy viewing. Further, the state where the grip portion 215a is in the second position is shown by a broken line.

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

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

5. Modifications Various modifications and changes are possible without being limited to the above-described embodiment, which are also within the scope of the present disclosure. Some modifications are given below.

(A) Deformation example of the support portion A modification of the support portion 310 will be described. In the above-described first embodiment, with respect to the structure of the adjacent portion between the left side panel 130 and the back panel 140, as shown in FIG. 15B, the partial support portion 310a of the left side panel 130 and the partial support portion 310b of the back panel 140 are screwed. An integral support portion 310 is formed by connecting with the connecting portion 341. However, the partial support portion of the support portion 310 is not limited to this.

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

40 (a) and 40 (b) are diagrams showing other structural examples. In FIG. 40 (a), the left side panel 130 and the back panel 140 are fitted with a semicircular convex male support portion 311a and a semicircular concave female support portion 311b. It shows a state in which the male support portion 311a and the concave female support portion 311b are locked by the relationship and form an integral support portion 310. In this case as well, a strong assembled state can be obtained as in FIG. 39. The structure of FIG. 40 (a) is not only a method of shifting the panel in parallel in the Z direction, but also, as shown in FIG. 40 (b), the left panel 130 is in the Z direction with the female support portion 311b as a fulcrum. By rotating around the axis in the −Y direction until a certain angle, the engaged state can be easily released, and the workability of assembly and disassembly can be remarkably improved.

41 (a) and 41 (b) are views of the outer panel surface and the inner panel surface of the back panel 140 in a plan view from a direction perpendicular to the panel surface, as in FIG. 12 of the first embodiment. It is a figure. The difference from the first embodiment is that the outer panel 140B is composed of only the support portion 323. Since the support portion 323 also serves as the protective material 322, the support portion 310, and the frame portion 320 constituting the outer panel 140B of the first embodiment with the same member, the number of parts of the heat insulating container can be reduced. ..

(B) Deformation example of inner panel (1)
A modified form relating to the shape of the contact portion between the heat insulating portions 330 of the adjacent inner panels will be described. The material and shape of the contact portions between the heat insulating portions 330 are not limited to the shape shown in FIG. 15B described in the first embodiment, and various materials and various shapes can be applied. In FIGS. 42 to 45, only the heat insulating portion 330 of the inner panel 130A of the left side panel 130 and the heat insulating portion 330 of the inner panel 140A of the back panel 140 are taken out, and the contact portions between the heat insulating portions 330 are perpendicular to each other in the Z direction. It is a cross-sectional view cut by a plane.

FIG. 42A is a diagram showing an example in which a flexible and flexible elastic body 337 is attached to the end surface of the heat insulating portion 330 of the back panel 140. When such a shape of the contact portion is adopted, the airtightness of the heat insulating container is further improved, so that the heat insulating performance of the heat insulating container is improved. The material of the elastic body 337 is not particularly limited, and various elastomer materials, sponge materials, and the like can be used.

FIG. 42B shows an example in which the cross-sectional shape of the end surface of the heat insulating portion 330 of the back panel 140 is an arcuate convex shape, and the cross-sectional shape of the end face of the heat insulating portion 330 of the left side panel 130 is an arcuate concave shape. It is a figure. When such a shape of the contact portion is adopted, the airtightness of the heat insulating container is further improved, so that the heat insulating performance of the heat insulating container is improved. Further, due to this shape, both heat insulating portions are compared with the case where the end surface of the heat insulating portion 330 of the back panel 140 is inclined perpendicular to the panel surface as shown in FIGS. 15 (b) and 42 (a). The contact area of the contact portion can be made large, and the load applied to the contact portion due to the heat insulating portions being pressed against each other can be dispersed by the large contact area. As a result, even when the heat insulating portion contains the vacuum heat insulating material, the vacuum heat insulating material can be less likely to be damaged.

In FIG. 43, tapered surfaces having an inclination that is not perpendicular to the panel surface are formed on each of the end surface of the heat insulating portion 330 of the back panel 140 and the end surface of the heat insulating portion 330 of the left side panel 130, and the tapered surfaces are connected to each other. It is a figure which shows the example which made the shape which abuts with. When such a shape of the contact portion is adopted, the contact area between the ends of the heat insulating portion 330 becomes larger and the adhesion of the contact portion is further improved, so that the heat insulating performance of the heat insulating container is improved. Also in the case of this shape, as described above, it is possible to prevent the vacuum heat insulating material from being damaged.

44 (a), 44 (b), 45 (a), and 45 (b) show the contact portion between the end surface of the heat insulating portion 330 of the back panel 140 and the panel surface of the heat insulating portion 330 of the left side panel 130. It is a figure which shows the example which is the shape which forms various fitting relations. When such a shape of the contact portion is adopted, the boundary line length of the heat insulating portion 330 of the contact portion becomes long, it becomes difficult for air from the outside to flow in, and the contact portion of the panel is formed by an external force or the like. Since it is difficult to slip off, the heat insulating performance of the heat insulating container is improved. When there is a convex shape on the heat insulating space side, that is, on the + X direction side of the end surface of the heat insulating portion 330 of the back panel 140 as shown in FIGS. 44 (b) and 45 (b), the heat insulating portions are more difficult to come off. Further, when the convex shape is a wedge shape as shown in FIG. 45 (b), it becomes more difficult to come off. In the case of these shapes as well, as described above, it is possible to prevent the vacuum heat insulating material from being damaged.

Further, although the above description is given by taking the left side panel 130 and the back side panel 140 as an example, the same applies to the relationship between the other panels.

(C) Deformation example of side panel (1)
An example of modification of the structure of the side panel 110 will be described. In the first embodiment described above, the left panel 130, the back panel 140, the right panel 120 and the front panel 150, which are the respective parts of the side panel 110, are all individually separable. However, the present invention is not limited to this, and some or all of the panels constituting the side panel may be inseparably connected.

46, 47, and 48 are views for explaining an example in which the side panel 110 is a partially connected panel. FIG. 46 shows a side panel 110C in which the left side panel 130, the back panel 140, and the right side panel 120 are connected by a connecting portion 361, and a front panel 150 which is a side panel 110D other than 110C. It is a figure which shows. FIG. 47 is a diagram showing that the left side panel 130, the back panel 140, the right side panel 120, and the front panel 150, which are all of the side panels 110, are the side panels 110C connected by the connecting portion 361. .. In FIG. 48, of the side panels 110, the left side panel 130 and the back panel 140 are connected by the connecting portion 361, and the front panel 150 and the right side panel 120 are connected by the connecting portion 361. It is a figure which shows that it is a side panel 110D other than 110C.

In this way, by partially connecting the side panel 110 by the connecting portion 361 in advance for a plurality of panels, the workload of assembling and disassembling the heat insulating container 100 can be significantly reduced. In particular, by forming the connecting portion 361 with a rotatable hinge or the like or a hook-and-loop fastener or the like, the volume after folding can be reduced. Further, the panel to be connected is not limited to the side panel 110, and may be, for example, one that connects any of the side panels 110 to the top panel 170.

(D) Deformation example of side panel (2)
A modified example of a heat insulating container having no opening / closing portion on the side panel will be described. FIG. 49 is a diagram showing a heat insulating container 100D having no opening / closing portion by a hinge or the like. The main difference from the heat insulating container 100 of the first embodiment described above is that the front panel 150 does not have an opening / closing part, the front plate part 151, the front door part 161 and the hinge 101 for rotating the front door part, and the like. Is. Since there is no opening / closing part, the strength of the side panel can be increased.

(E) Deformation example of inner panel (2)
A modified form relating to the configuration of the heat insulating portion 330 of the inner panel will be described. In the first embodiment, the heat insulating portion 330 is an example in which the foam heat insulating material 332 is arranged at a position adjacent to at least one main surface of the vacuum heat insulating material 331 as shown in FIGS. 13 (a) and 13 (b). explained. However, the structure of the heat insulating portion 330 is not limited to this. 50 (a) and 50 (b) are cross-sectional views showing an example in which the foamed heat insulating material 332 is divided into two to form the heat insulating portion 330.

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

In FIG. 50 (b), the point that the foamed heat insulating material 332e and 332f divided into two are used is the same as in FIG. 50 (a), but the adhesive 336 is discontinuously arranged in the foamed heat insulating material 332f. Is formed with a recess for applying the adhesive 336. Thereby, the heat bridge due to the adhesive 336 having a relatively low heat insulating property can be suppressed.

In FIG. 52A, the end surface of the inner panel 130A of the left panel 130 and the end surface of the inner panel 120A of the right panel 120 are in contact with the panel surface of the inner panel 170A of the top panel 170, and the inside of the bottom panel 190 is shown. It is a figure which shows that the end surface of the inner panel 130A of the left side panel 130 and the end face of the inner panel 120A of the right side panel 120 are in contact with the panel surface of the panel A.

In FIG. 52B, the end surface of the inner panel 130A of the left side panel 130 and the end surface of the inner panel 120A of the right side panel 120 come into contact with the panel surface of the inner panel 170A of the top surface panel 170, and the inside of the bottom panel 190. It is a figure which shows that the panel surface of the inner panel 130A of the left side panel 130 and the panel surface of the inner panel 120A of the right side panel 120 are in contact with the two end faces of the panel 190A. In FIG. 53A, the inner panel 170A of the top panel 170 is in contact with both the end of the outer panel 130B of the left panel 130 and the end of the outer panel 120B of the right panel 120 so as to project. The figure which shows that the panel surface of the inner panel 130A of the left side panel 130 and the panel surface of the inner panel 120A of the right side panel 120 are in contact with the two end faces of the inner panel A of the bottom panel 190 which is mounted. Is.

In FIG. 53B, the inner panel 170A of the top panel 170 is in contact with both the end of the outer panel 130B of the left panel 130 and the end of the outer panel 120B of the right panel 120 so as to project. It is a figure explaining that the end surface of the inner panel 130A of the left side panel 130 and the end face of the inner panel 120A of the right side panel 120 are in contact with the panel surface of the inner panel A of the bottom panel 190. ..

Is a structure in which the panel surface of the inner panel 170A of the top panel 170 is in contact with the end surface of the inner panel 130A of the left panel 130 and the end surface of the inner panel 120A of the right panel 120, respectively. These structures are advantageous in that even if the mounting position of the top panel 170, which is easily displaced when the lid is closed, is slightly displaced, the heat insulating portions can surely come into contact with each other, and the mounting position of the top panel 170 is stable. The tolerance can be expanded.

Next, a modified example of the arrangement of the four side panels 110 and the adjacent state will be described. In the above-described first embodiment, an example of arranging four panels of the side panel 110 has been described with reference to FIG. 15A, but the method of arranging the panels is not limited to this. 57 (a) and 57 (b) are views showing a modified form of the panel arrangement method.

Therefore, the impact force when closing the front door portion 161 is not transmitted to the inner panel 150A of the front panel 150, but is transmitted only to the end surface of the inner panel 130A of the left side panel 130 and the end surface of the inner panel 120A of the right side panel 120.

In FIG. 57B, the end surface of the inner panel 130A of the left side panel 130 and the end surface of the inner panel 120A of the right side panel 120 are in contact with the panel surface of the inner panel 140A of the back panel 140, and the inner panel of the front panel 150 is shown. It is a figure which shows that the end surface of the inner panel 130A of the left side panel 130, and the end face of the inner panel 120A of the right side panel 120 are in contact with the panel surface of 150A. In the structure of FIG. 57B, when the front door portion 161 is closed, the panel surface of the inner panel 150A of the front panel 150 is the end surface of the inner panel 130A of the left side panel 130 and the end surface of the inner panel 120A of the right side panel 120. It has a structure that comes into contact with. Therefore, the impact force when closing the front door portion 161 is transmitted to the panel surface of the inner panel 150A of the front panel 150, the end surface of the inner panel 130A of the left side panel 130, and the end surface of the inner panel 120A of the right side panel 120.
