Description

  The invention of the present application is a folded heat insulation panel suitable for producing a heat insulation container by folding and assembling into a box shape, a bent heat insulation panel with a sensor capable of temperature control, vacuum control, communication with the outside, etc., and the inside is evacuated The present invention relates to a vacuum-type folded heat insulation panel and a heat insulation container using these panels.

  In recent years, heat insulating materials made of various materials such as foamed polystyrene, glass fiber, rock wool, and foamed urethane are available. Some vacuum insulation materials have higher insulation performance than those insulation materials. The vacuum heat insulating material covers the outer periphery of the heat insulating material (core material) with a jacket material (film, sheet) having a gas barrier property, and the inside of the core material and the jacket material is depressurized to be in a vacuum state (high vacuum state). It is a heat insulating material with improved heat insulating performance.

  Heat insulating materials and vacuum heat insulating materials are used in various fields as wall materials for cold storage containers, refrigerators, freezer rooms and the like (hereinafter collectively referred to as “heat insulating containers”), wall materials for houses, and the like.

  In order to make a heat insulating container using a heat insulating material or a vacuum heat insulating material, it was necessary to assemble a plurality of plate-shaped heat insulating materials or a vacuum heat insulating material into a box shape or to form a box shape with the heat insulating material. However, the former is cumbersome to assemble, and the latter heat-insulating container has a three-dimensional shape and has a fixed size, which makes it bulky and inconvenient to store, store and transport when not in use.

  Conventionally, there is a bendable heat insulation panel and a heat insulation box using the same (Patent Document 1). If this heat insulating panel is used, it is easy to produce a heat insulating container, but it cannot be used as a wall surface because the heat insulating panel is wavy.

  When items that require cold storage such as foodstuffs, food, cosmetics, medicines, and living organisms are stored in an insulated container and transported by car, train, etc., in order to maintain the freshness and quality of these items,・ Outside temperature management is important, so there is a demand to be able to manage these temperatures even in remote locations. However, conventionally, there has been proposed a technique for improving the heat insulating performance of a heat insulating material or a vacuum heat insulating material (Patent Document 2), but no proposal of a heat insulating material that can cope with temperature management has been found.

(Bend insulation panel)
An example of the folded heat insulation panel of the present invention will be described below. As long as the bent heat insulating panel of the present invention includes the bent portion 1, the heat insulating panel 2 may be covered with the jacket material 3 (FIG. 2) or may not be covered (FIG. 1). When covered with the jacket material 3, the battery 25 and the sensors 4 may be housed (built-in) (FIG. 2) or may not be built-in. When it coat | covers with the jacket material 3, the thing which evacuated the inside may not be evacuated.

  As an example of the folded heat insulation panel of the present invention, the one shown in FIGS. 1A and 1B is one in which the heat insulation panel 2 is not covered with a jacket material and is a sheet (including a plate). The heat insulation panel 2 is provided with four peripheral wall panels 5. Two or more through holes 6 are opened in an example at a boundary portion of the four peripheral wall panels 5 to form a bent portion 1. Four peripheral wall panels 5 can be bent from the bent portion 1 to form a peripheral wall of a heat insulating container 7 of a container having a container main body (heat insulating container 7) and a lid as shown in FIG.

  As an example of the folded heat insulating panel of the present invention, what is shown in FIG. 2A is the one in which the bent heat insulating panel shown in FIG. 1A is a core material 8 and the outer periphery thereof is covered with a sheet-like jacket material 3. . It is preferable to use a material having excellent gas barrier properties for the jacket material 3. The jacket material 3 may be in the form of a film or plate (thin plate, thick plate). The peripheral wall of the container main body (heat insulating container) 7 can be formed by bending the four peripheral wall panels 5 from the bent portion 1 formed by two or more through holes 6 as shown in FIG.

  As shown in FIGS. 3A and 3B, the bent portion 1 has a V-shaped groove 9 formed on the upper surface of the heat insulating panel 1 or a V-shaped groove 9 formed on the upper surface of the heat insulating panel 1. Other shapes and structures that are easy to bend, such as the groove 9, can be made U-shaped, such as making a linear notch 10. Several linear cuts 10 can be made if necessary to facilitate bending. The heat insulating panel 2 shown in FIG. 3A can be hermetically covered with the outer cover material 3 on the outer periphery (front and rear surfaces and outer peripheral surface).

  The heat insulation panel 2 shown to Fig.4 (a) provides the jacket material 3 in the back surface, and connects the four panels 5 for surrounding walls. As shown in FIG. 4B, the heat insulating panel 2 can be folded with the outer covering material 3 outside to assemble the peripheral wall 7 of the container body.

(Insulation panel)
The heat insulating panel 2 has a heat insulating property that can be used as a peripheral wall or a bottom plate of the heat insulating container 7, a plate thickness, a strength, and the like, and a flexible material that can be bent is suitable. For example, fiber materials such as glass wool, ceramic fiber and rock wool, powder such as powdered silica, organic or inorganic foam, paper (thick paper, laminated paper) and the like can be used. Styrofoam, FRP, etc. can also be used, but in the case of a vacuum-type folded heat insulation panel, the heat insulation panel 2 can be decompressed when it can discharge a lot of air, and can be in a high vacuum state. A so-called porous material having many voids and pores (hereinafter referred to as “voids”) is desirable. Styro homes can also be used, but they are easy to break, so care must be taken depending on the situation. Glass wool has the property of being difficult to break. The material, shape, size, thickness, etc. of the heat insulating material are designed according to the use of the vacuum heat insulating panel with sensor. The heat insulation panel 2 is not limited to the one exemplified here, and other materials that have been conventionally used as heat insulation materials can also be used.

(Linked shape)
The heat insulation panel 2 can be formed in another continuous shape instead of connecting the four peripheral wall panels 5 in a horizontal row as shown in FIGS. 1 (a) and 2 (a). For example, the shape shown in FIGS.

  The heat insulating panel 2 in FIG. 5A has a cross shape in which four peripheral wall panels 5 are connected to four sides of one bottom plate panel 12, and is formed at the boundary between the bottom plate panel 12 and the peripheral wall panel 5.

The outer part (gray part) 14 is heat-sealed from the outer peripheral edge. The heat insulating panel 2 can be formed by punching a heat insulating material (for example, glass wool) wound in a roll shape into a cross shape as shown in FIGS. Simultaneously with this punching, the through hole 6 can also be punched and penetrated.

  As shown in FIG. 5 (b), the folded heat insulating panel of FIG. 5 (a) raises four peripheral wall panels 5 to the four sides of the bottom panel 12 to form a heat insulating container 7 having a bottom and a peripheral wall. can do. In this case, the surplus portion 15 (FIG. 5 (a)) of the covering material 3 formed between the four peripheral wall panels 5 (four corners) is folded as shown in FIG. 5 (Figs. 6 (a) and 6 (b)), and it is preferable that the outer container 16 (Figs. 6 (a) and 6 (b)) separately formed with a heat insulating material is easily accommodated inside. Reference numeral 17 in FIG. 6B denotes a lid made of a heat insulating material, and 18 denotes a heat insulating panel for the lid made of heat insulating material attached to the inner surface thereof. The heat insulating panel 18 for the lid is also preferably a vacuum type in terms of heat insulating properties.

  Various methods for punching the cross-shaped heat insulation panel 2 as shown in FIG. 5 are conceivable. For example, as shown in FIG. 7, the center portion in the width direction of the roll-shaped raw fabric 20 is punched into a cross shape, At the same time, the through hole 6 is opened at the boundary between the bottom plate panel 12 and the peripheral wall panel 5 to form the bent portion 1, and simultaneously with the punching and punching, the lid heat insulating panel 18 is inserted from both ends in the width direction of the original fabric 20. The heat insulation panel 2 can be formed by punching to reduce waste of the raw fabric 20.

  As shown in FIG. 8, the cross-shaped heat insulation panel 2 is punched in two rows in a zigzag arrangement on both sides in the width direction of the original fabric 20, and simultaneously penetrates the boundary between the bottom plate panel 12 and the peripheral wall panel 5 The bent portion 1 is formed by opening the hole 6. Simultaneously with the punching and punching, the heat insulating panel 18 for the lid can be punched from both ends in the width direction of the original fabric 20 to reduce waste of the original fabric 20.

  As shown in FIGS. 7 and 8, the front and back surfaces of the heat insulation panel 2 punched into a cross shape are covered with a cross-shaped sheet material 3 having a size slightly larger than the cross shape. It is also possible to heat-seal the outer peripheral edge. In that case, the heat insulating container 7 can be assembled by raising the peripheral wall panel 5 covered with the jacket material 3 above the bottom plate panel 12 covered with the jacket material 3. In this case, since gaps are formed at the joints at both ends of the four peripheral wall panels 5, it is preferable to seal the gaps by any means to ensure heat insulation. For example, a heat insulating material is applied to the joint portion, and the heat insulating material is bonded to the four peripheral wall panels 5 and the bottom plate panel 12 so as to close and connect the gaps of the joint portions to be insulated. Can do.

(Longitudinal L-shaped connection pattern)
The heat insulation panel 2 in FIG. 9A is a series of four peripheral wall panels 5 and one bottom plate panel 12 arranged in a horizontally long L shape, and the boundary between the peripheral wall panel 5 and one bottom plate panel 12. A through-hole 6 is opened at a portion and a bent portion 1 is provided. In the case of manufacturing a heat insulating container with this bent heat insulating panel, the four peripheral wall panels 5 are bent from the bent portion 1 and raised around the bottom panel 12 to insulate as shown in FIG. A container 7 can be formed.

  As shown in FIG. 9 (b), the heat insulating panel 2 in FIG. 9 (a) is punched out of the heat insulating material 20 with a set of five heat insulating panels 2 facing each other, and simultaneously with the punching, for the four peripheral walls. By opening the through-hole 6 at the boundary between the panel 5 and the single bottom panel 12, the heat insulating panel 2 having the bent portion 1 can be formed, and the waste of the raw fabric 20 can be reduced. .

(T-shaped connection pattern)

When manufacturing a heat insulation container with this heat insulation panel 2, three peripheral wall panels 5 can be bent from the bent portion 1 and can be raised around a single bottom plate panel 12 to form a peripheral wall. In this case, among the four peripheral walls, a separately formed heat insulating panel 2 may be disposed on the peripheral wall portion that is insufficient, and connected to the three peripheral walls to form the four peripheral walls. it can.

  The heat insulation panel 2 in FIG. 10A is formed by punching from the heat insulating material 20 as shown in FIG. 10B, and forming the bent portion 1 by opening the through hole 6 simultaneously with the punching. It can be formed with less waste of the raw fabric 20.

(Three-sided connection pattern)
The heat insulation panel 2 in FIG. 11 (a) is formed by connecting two peripheral wall panels 5 and one bottom plate panel 12, and forming a bent portion 1 by opening a through hole 6 at a boundary portion between the panels.

By doing so, it is possible to form the bent portion 1 and reduce the waste of the original fabric 20.

(Bent part)
The through hole 6 of the bent heat insulating panel of the present invention may be other than a perfect circle, for example, may be elongated. Regardless of the shape of the hole, the size, size, spacing, etc. of the heat insulation panel 2 are made to be easy to bend and have a thickness and strength that will not cut even when bent. The number of heat insulation panels to be connected, the vertical and horizontal dimensions, etc. are designed according to the shape and size of the heat insulation container 7 to be manufactured.

(Sensors, unitized)
An accommodation recess 11 is formed in the heat insulation panel 2, and the sensors 4 are accommodated in the accommodation recess 11. The sensors 4 are unitized as shown in FIGS. 12 and 13, for example. As an example of unitization of the sensors 4, what is shown in FIG. 13 is a temperature sensor 26, a vacuum sensor 27, a communication unit 28 capable of wirelessly or wiredly communicating detected data detected by these sensors, and a communication antenna. 29, a data logger (storage element) 30 capable of storing data detected by the sensors is mounted on one surface (front surface) of one circuit board 31 and a battery holder 32 is mounted on the opposite surface (back surface) of the circuit board 31. The battery holder 32 is equipped with a battery 25. The circuit board 31 can be made of hard glass epoxy. As the sensors 2, a humidity sensor, an acceleration sensor, and any necessary battle can be provided in addition to the sensors. As the circuit board 31, a flexible material made of a resin film or the like can be used. In this case, as shown in FIG. 12, the temperature sensor 26 and a communication unit 28 displaying a communication circuit are displayed on the flexible circuit board 31. And then the antenna 29 can be pulled out and the battery 25 can be provided on the back side.

  The battery 25, the temperature sensor 26, and the like can be individually accommodated in the housing recesses by providing the heat insulation panel 2 with a plurality of housing recesses without being unitized. If it does in this way, a vacuum type bending heat insulation panel can be made thin. The temperature sensor 26 senses the temperature inside the heat insulating panel 2 or the jacket material 3, and the humidity sensor senses the humidity inside the jacket material 3. The humidity detected by the humidity sensor is the moisture that has entered the inside of the jacket material 3 from the outside due to deterioration or loss of the gas barrier property of the jacket material 3. Since the acceleration sensor can sense the vibration of the heat insulating container with the heat insulating sensors of the present invention attached, the vibration of the cold insulating product in the heat insulating container is accommodated when the cold insulating product is accommodated and transported in the heat insulating container. The situation can be ascertained and used for quality control of refrigerated products.

  The sensors 4 are accommodated in the accommodating recess 11 and fixed with an adhesive, or the openings of the accommodating recess 11 are sealed with tape or the like (not shown) after the sensors 4 are accommodated. It does not fall off from the housing recess 11. The units of the housing recess 11 and the sensors 4 can be provided in one or more of the bottom plate panel 12 and the peripheral wall panel 5. The battery 25, the temperature sensor 26, and the like can be individually housed in the housing recess 11 by providing a plurality of housing recesses 11 in the heat insulating panel 2 without being unitized. If it does in this way, a vacuum type bending heat insulation panel can be made thin.

  The temperature sensor 26 senses the temperature inside the outer jacket material 3 of the bent heat insulating panel and the heat insulating container 7 manufactured by the temperature sensor 26, and the humidity sensor detects the humidity inside the outer heat insulating material 7 of the bent heat insulating panel and the heat insulating container 7 manufactured therefrom. The acceleration sensor can sense the vibration of the bent heat insulating panel or the heat insulating container 7 made of the bent heat insulating panel.

  By providing the acceleration sensor, when the heat insulating container 7 is manufactured with the bent heat insulating panel of the present invention, and the cold storage product is accommodated in the heat insulating container 7 and transported, the vibration status of the cold storage product in the heat insulating container 7 is determined. Since it can be grasped, the vibration state can be used for quality control of the cold-retaining products.

(Battery)
The battery 25 is for operating the temperature sensor 26, the vacuum sensor 27, the data logger 30, and the communication unit 28. The battery 25 can be a lithium battery or other long-life battery. The battery can be rechargeable or non-rechargeable. In the case of the rechargeable type, charging can be performed by providing a power supply connector for charging (for example, an outlet) outside the jacket material 3 and connecting a power source thereto. In recent years, non-contact type charging, for example, a charging method using electromagnetic waves for charging has been studied, and since there is a possibility of practical use, a battery that can be charged in a non-contact type can also be used. Various batteries including a lithium battery are generally known to easily deteriorate in a low temperature environment and a high humidity environment, and the life is extremely shortened. Since it is covered, the battery 25 can be isolated from the low-temperature environment or the high-humidity environment by providing the battery 25 inside the heat insulating panel 2 or the jacket material 3.

  Various arrangement positions and arrangement structures of the sensors 4 can be considered. The main examples are shown in FIGS. 15 (a) to 15 (c) and FIGS. 16 (a) and 16 (b).

  In FIG. 15C, the circuit board 31 is placed on the heat insulation panel 2 so that the vacuum sensor 27, the data logger 30, the communication unit 28, and the battery 25 are accommodated in the accommodation recess 11 of the heat insulation panel 2. Thus, they can be protected from impacts and the like.

The temperature sensor 26 led out to the opposite side in the thickness direction (lower surface: back surface) and attached to the lead-out portion 33 is arranged on the back surface side of the heat insulating panel 2.

The circuit board 31 is housed in the housing recess 11 provided, and is led out through the guide holes and guide grooves provided in the heat insulation panel 2 to the opposite side (lower surface: back surface) of the heat insulation panel 2, and the lead-out portion 33. The temperature sensor 26 attached to is disposed on the back side of the heat insulation panel 2.

  The housing recess 11 can be provided on either the upper surface (the surface that becomes the inside of the heat insulating container) or the lower surface of the heat insulating panel 2.

(Coating material)
As the jacket material 3, a film, a sheet, or a plate can be used. In order to maintain the inside of the jacket material 3 in a vacuum state, the jacket material 3 needs to be made of a material having excellent gas barrier properties. Materials with excellent gas barrier properties include metal plates such as stainless steel, aluminum, and iron, plastic (resin), composite materials in which metal foil and plastic film are laminated, composite materials in which metal is deposited on plastic, metal sheets and resin sheets Composite materials with a laminated structure in which materials such as woven fabrics and nonwoven fabrics made of resin fibers or natural fibers are laminated with films and sheets made of gas barrier resin, metal foil, etc. is there. The material, thickness, shape, size, composite structure and the like of the jacket material 3 can be designed according to the purpose of use.

  The outer covering material 3 can be used alone in the form of a film or a sheet, but one surface (lower surface) of the heat insulating panel 2 is covered with the plate-shaped outer covering material 3 and the opposite side surface (upper surface) is a sheet. Covered with a sheet-like or film-like jacket material 3, or plate-like jacket materials 3 are arranged on both surfaces (lower surface and upper surface) of the heat insulation panel 2, and the outer peripheral parts of the upper and lower jacket materials are film-like or sheet-like. The heat insulation panel 2 can also be covered by combining film-like, sheet-like, and plate-like things, such as covering with the outer covering material 3. The material, shape, size, thickness, strength, etc. of the jacket material 3 are also designed according to the usage of the bent heat insulating panel. The jacket material 3 can be made of the same or different material and structure (both of which have gas barrier properties) to cover the heat insulating panel 2, and by the double coating, by any chance, Even if the workpiece 3 is damaged, the vacuum state inside the jacket 3 is secured.

  The metal jacket material 3 including aluminum is suitable for detecting the temperature with the temperature sensor 26 provided inside the jacket material 3 because of its excellent gas barrier property and thermal conductivity. Due to the shielding characteristic (radio wave shielding), the data in the jacket material 3 detected by various sensors is not suitable for transmitting to the outside by the communication unit 28 housed inside the jacket material 3. In that case, it is desirable to cover only the outer part of the communication unit 28 with the outer covering material 3 made of a material having a gas barrier property but not a radio wave shielding property (a radio wave transmitting material).

  The outer covering material 3 can be made of resin. Resin has not only a gas barrier property but also a property that it does not have a radio wave shielding property. Therefore, it is suitable in terms of communication, contrary to metal, but is provided in the jacket material 3 because of its low thermal conductivity. The temperature sensor 26 is not suitable for measuring the ambient temperature. In order to make use of all these characteristics, it is possible to use a combination of a metal and a resin jacket 3. As an example, a metal having high thermal conductivity, such as aluminum, is used in the range close to the temperature sensor 26 (covers the temperature sensor), and the radio wave shielding property is close to the range close to the communication unit 28 (covers the communication unit). It is desirable to use no resin.

  When temperature detection by the temperature sensor 26 and communication by the communication unit 28 are considered, selection of the material of the jacket material 3 used near the temperature sensor 26 and the communication unit 28 is important. As described above, the metal material has a characteristic of high thermal conductivity, whereas it has a characteristic of easily absorbing radio waves, and a resin has a characteristic of low thermal conductivity and easy transmission of radio waves. In the case of the bent heat insulation panels shown in a) to (c), the portion where the antenna 29 is arranged uses a resin having good radio wave transmission, and the portion where the temperature sensor 26 is arranged uses a metal material having high thermal conductivity. Is desirable.

  In the case of a bent heat insulating panel with a sensor, the entire outer cover material 3 is made of a metal having high thermal conductivity, and only the area covering the antenna 29 (FIG. 15) is partially made of a resin material having good radio wave transmission. You can also. Alternatively, the whole can be made of a resin material, and only the range covering the temperature sensor 26 can be made of a metal material partially.

(Vacuum-type folding insulation panel)
The folded heat insulation panel of the present invention in which the outer side of the heat insulation panel 2 is covered with the jacket material 3 can be made into a vacuum folded heat insulation panel by evacuating the inner side of the core material 8 and the jacket material 3. In this case, the inside of the jacket material 3 is depressurized by the vacuum pump P (FIG. 14) to make a vacuum state of a predetermined degree of vacuum (reference pressure) Pa, and then the vacuum pump P is detached from the jacket material 3 and By sealing (sealing) the opening after removal, the inside of the heat insulating panel 2 (core material 8) and the jacket material 3 can be maintained at a predetermined degree of vacuum. Sealing of the opening after removing the vacuum pump P can be performed by various means such as sealing with an adhesive or heat welding. For example, when the jacket material 3 is a metal plate such as aluminum, a film, a sheet, etc., since heat sealing is difficult, a combination of PET materials that are easy to heat seal (bonding, vapor deposition, etc.) Can be used.

  The space in the accommodating recess 11 in which the sensors 4 are accommodated can be injected with a highly heat-conductive filler before the outer covering material 3 is covered, or can be left as a gap. It is preferable that the battery 25 is disposed at the substantially central portion in the thickness direction of the heat insulating panel 2 so as to be hardly affected by an external low temperature / high humidity environment.

  Some heat insulation panels 2 have many voids inside, and some of them can discharge the air in the voids by evacuation or the like by a suction machine. In such a heat insulating panel 2, the inside of the heat insulating material is also decompressed by reducing the pressure inside the jacket material 3 with a vacuum device to form a vacuum state. Since the subsequent vacuum state is difficult to be maintained when the heat insulating panel 2 is damp, in order to make the inside of the jacket material 3 vacuum, a degassing operation (decompression operation) is performed while sending dry air. It is desirable to carry out below.

(Vacuum sensor)
In the case of a bent heat insulation panel in which the inner side of the jacket 3 is in a vacuum state, the vacuum state needs to be detected by the vacuum sensor 22 in order to maintain the vacuum state. The vacuum sensor 22 includes various types such as a Pirani vacuum gauge, a diaphragm vacuum gauge, a capacitance type vacuum sensor, a micro mechanical vacuum sensor, and the like. Various vacuum sensors can be used as long as the vacuum sensor that can be used in the vacuum-type folded heat insulating panel of the present invention can detect the vacuum state inside the jacket material 3. The vacuum sensor 27 is desirably as small and thin as possible in order to be housed inside the heat insulating panel 2 or the jacket material 3. Since the vacuum state means a reduced pressure state, for example, a pressure sensor can be used as the vacuum sensor.

  In FIG. 14, the vacuum sensor 27 is operated by the power source B supplied from the battery 25 (FIG. 13B), the pressure inside the jacket 3 is detected by the vacuum sensor 27, and the detected current (voltage) is By amplifying with the amplifier A and comparing the output voltage of the amplifier A with a proper vacuum state (appropriate pressure in the jacket 3: reference pressure) Pa required by the folded heat insulating panel of the present invention in the comparator C. It is possible to determine whether or not the inside of the jacket material 3 is maintained in an appropriate vacuum state. In FIG. 14, the detected pressure is displayed on the digital meter M so that the vacuum state inside the jacket material 3 can be confirmed. When the output of the comparator C is higher than the reference pressure Pa, the solenoid valve of the vacuum pump P can be opened by the relay R, and the inside of the jacket material 3 can be decompressed by the vacuum pump P. The vacuum sensor 27 may be entirely provided in the jacket material 3, but may be attached by partially protruding outside the jacket material 3. In either case, it is attached so that the vacuum state in the jacket 3 is not impaired.

  The vacuum data detected by the vacuum sensor 27 in FIG. 14 is wirelessly transmitted to, for example, an external management center or other equipment from the communication unit 28 (FIG. 13) provided on the inner side of the jacket material 3, and the management center or other equipment is transmitted. It is also possible to check and manage vacuum abnormalities by processing data. The communication can also be performed by wire. In the case of a wireless system, an antenna 29 can be built in or externally attached to the communication unit 28. In the case of a wired system, a connector or other connection device (connector) that can be electrically connected to an external device is provided outside the jacket material 3, and wired communication is performed with the external device connected thereto. Can do.

  In the present invention, the vacuum data (for example, pressure data) detected by the vacuum sensor 27 is stored in a data logger provided on the inner side of the jacket material 3, and the stored data is stored in, for example, an external management center or other It is also possible to manage the vacuum state by checking the abnormality of the vacuum state by processing at the place.

(Insulated container)
The heat-insulating container of the present invention is suitable for use as a heat-insulating container for delivery that accommodates and delivers a cold-retained product. The container manufactured by assembling the folded heat insulation panel of the present invention can be used as it is as the heat insulation container 7 (having a bottom and a peripheral wall, and the lid is separate), but if necessary, the heat insulation container 7 is molded separately. A heat insulating container having a double structure can be formed by being housed and disposed inside the outer container 16 (FIG. 6) made of heat insulating material. Depending on the case, it can also be arrange | positioned on the outer side of the outer container 16 separately shape | molded (it uses as an outer container), and can also be set as a double-structured heat insulation container. In the case where the heat insulating container 7 is arranged as an inner container, it is preferable to measure the temperature in the heat insulating container 7 when the temperature sensor 26 (FIGS. 15 and 16) is arranged on the inner surface of the heat insulating container 7. Placing the battery 25 outside the heat insulating container 7 is preferable in that the battery 25 is protected from the low temperature and high humidity environment in the heat insulating container 7.

  The heat insulating container insulates the inside of the housing space from the outside, and can manage the temperature in the housing space using the temperature data detected by the temperature sensor 26. Also in this case, the degree of vacuum inside the jacket 3 is detected by the vacuum sensor 27 (FIG. 13), and the degree of vacuum of the vacuum-type folded heat insulation panel is monitored, and the vacuum data obtained by the vacuum sensor 27 is used. Can be vacuum controlled. Since the battery 25 is thermally insulated from the outside, the problem of deterioration (shortening of life) associated with a low temperature environment and a high humidity environment can be solved. In addition, since various data such as temperature data, vacuum data, humidity data, acceleration data, and the like obtained by various sensors can be transmitted to the outside by the communication unit 28, heat insulation such as temperature and humidity in the housing space of the heat insulating container 7 can be used. The movement state of the container 7 can be monitored and managed.

(Mounting sensors)
In the above description, the sensors 4 and the battery 25 are built in the jacket 3 of the heat insulation panel 2, but they may be attached to the surface of the jacket 3 of the heat insulation panel 2.

  It is desirable to increase the heat insulation efficiency in the outer container 16 by attaching a vacuum or non-vacuum heat insulating panel 18 for the cover to the inner surface of the cover 17 (FIG. 6) that covers the outer container 16 (FIG. 6).

  The folded heat insulation panel of the present invention can also be used as a building material such as a flooring material or an outer wall material.
