Specifically, the vacuum heat insulating panel with the sensor in which the temperature sensor capable of detecting the ambient temperature is installed and the cool container using the same are developed.

Description

  The present invention relates to a cold insulation container used for transporting articles that require cold insulation, such as foodstuffs, foods, cosmetics and medicines, and more specifically, a vacuum heat insulation panel provided with a sensor and the same. The present invention relates to the cold storage container used.

  In recent years, with the increase in working housewives and the increase in elderly households, the demand for food delivery services is expanding. The food delivery service is a service in which a food sales company delivers food to a consumer, and delivers food according to the order of the consumer about once a week.

  Ingredients to be delivered are not limited to those that can be controlled at room temperature, but also include refrigerated ingredients and refrigerated ingredients, so they are housed and transported in a cold storage container using a heat insulating material such as polystyrene foam. In addition, it may be delivered in the summer, or it may be left in a designated place (for example, in front of the entrance) without being handed over to the consumer, so put dry ice or a regenerator together with ingredients in the cold storage container. This is the current situation. Many food delivery companies ship dry ice in a cold storage container when delivering “refrigerated ingredients” and deliver a cold storage agent when delivering “refrigerated ingredients” to homes. ing.

  Thus, the conventional cold storage container cools the food in the cold storage container (maintains the cooled state) by cooling with dry ice or a cold storage agent and insulating with foamed polystyrene or the like. However, the thermal conductivity of Styrofoam is about 0.02 to 0.03 w / mk, which is the same as that of air, and is not so excellent in heat insulation, and the cooling capacity of dry ice and cold storage agent decreases with time. In the cold container, the food could not be kept cold for a long time.

  In the same way as regular home delivery, home delivery of ingredients visits multiple home delivery destinations in a single delivery, so it may take longer than expected depending on traffic conditions. Alternatively, the customer may be absent despite being delivered to the customer for delivery. In such a case, the courier cannot confirm the temperature state in the cold storage container, so he / she is at a loss whether to leave the food in the designated place or take it home.

  In addition, food may be delivered in a state where it is not kept cold due to failure of the cold storage container or forgetting to put dry ice or a cold storage agent. Usually, the courier does not check the inside of the cold storage container. In this case, the customer has the food that is not kept cold.

  In order to avoid such a situation, a wireless sensor having a sensor capable of detecting temperature is arranged in the cold insulation container, and a quality (temperature quality) management center is installed, and the cold insulation container having a temperature abnormality is collected. A system is also conceivable. However, in this case, the wireless sensor is exposed to low temperatures in the cold storage container, and as a result of being exposed to dew condensation caused by dry ice or a cold storage agent, the battery that is the power source of the wireless sensor deteriorates rapidly and does not function quickly. As a result, the system itself is not properly operated.

  Alternatively, as a current improvement measure, it is also conceivable to change the currently used cold storage container made of expanded polystyrene to a cold storage container using a material with higher heat insulation. This method is effective, but considering the fact that a large amount of cold storage containers are currently being used as demand for food delivery services increases, it takes time to deal with all the cold storage containers, so it is somewhat effective immediately. In addition, it cannot solve the problem that the temperature in the cold storage container cannot be controlled.

  In addition, it is conceivable that the dry ice and cold storage agent enclosed in the cold storage container may be increased from the usual design amount to prolong the coolable period, but the amount of dry ice and cold storage agent can be accommodated. The amount will decrease, making it difficult to adopt as a food delivery company. Therefore, Patent Document 1 proposes a cool container for home delivery in which a space is provided in the lid portion of the cool container, and dry ice and a cold storage agent can be stored in this space.

JP 2009-154966 A

However, according to Patent Document 1, since the volume of the whole cold storage container becomes large, and as a result, it is impossible to go around many consumer homes by one delivery, it is difficult to adopt as a food delivery company.

[Embodiment 1]
An example of an embodiment of the cold insulation container of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a cold container 1 of the present invention. The cold storage container 1 can store frozen food (refrigerated food), refrigerated food (frozen food), and the like. The container main body 2, the lid 3, the storage space 4, and the storage space 4 The sensor-equipped vacuum heat insulation panel 6 and the vacuum heat insulation panel 7 are provided. Note that refrigerated foods, frozen foods, and the like need to be kept at a low temperature until they are consumed, so these are referred to as “articles that require cold storage” or simply “cold foods” for convenience.

(Cold container)
As described above, the cold insulation container 1 is capable of accommodating and transporting “articles requiring cold preservation”, and the outer shape thereof is formed by the container main body 2 and the lid 3. Although this container main body 2 and the lid | cover 3 can also be created newly, the cold storage container B (shown in FIG. 2) currently utilized can also be utilized as it is. By effectively utilizing the existing cold storage containers B that are currently distributed in large quantities, it is possible to reduce the economic burden, reduce waste, and consider the natural environment. The container main body 2 and the lid 3 of the existing cold storage container B are made of a heat insulating material. Typical examples include polystyrene foam, but other urethane products may also be used. .

  FIG. 3 is a cross-sectional view of the cold insulation container 1 of the present invention as viewed from the front. As shown in FIG. 1 and FIG. 1, the container body 2 includes two front walls 2 a that stand and face each other, two side walls 2 b that stand and face each other, and the two front walls 2 a and 2 It is formed by a bottom wall 2c that closes the lower ends of the two side walls 2b, and an open upper accommodation space 4 is provided in these wall surfaces. In FIG. 1 and FIG. 3, the planar view shape including the four walls on which the container body 2 is erected is a rectangle. However, as long as the accommodation space 4 can be provided, the shape is not limited to this rectangle, but other shapes such as a plan view, for example. It can be a polygon, an oval, or any other shape.

  The lid 3 can be fitted over the container body 2 from above. When the lid 3 is installed on the container body 2, the accommodation space 4 is substantially sealed. It is desirable that the container body 2 and the lid 3 be securely fitted in order to shield (insulate) the cold-reserved food F (FIG. 3) stored in the storage space 4 from external heat. Therefore, as shown in FIG. 3, the upper part of the container body 2 is concave and the lower side of the lid 3 is convex, or conversely, the container body 2 side is convex and the lower side of the lid 3 is concave. Various means such as providing a protrusion and providing a groove (hole) on the other side can be used. However, as illustrated here, a means that allows easy attachment and detachment of the lid 3 is desirable.

  As shown in FIG. 1 and FIG. 3, the front wall 2a, the side wall 2b, the bottom wall 2c, and the inner surface of the lid 3 constituting the housing space 4 of the container body 2 (hereinafter collectively referred to as “the construction surface of the housing space 4”). ") Is equipped with a vacuum thermal insulation panel that is superior in thermal insulation compared to polystyrene foam. In this case, the vacuum heat insulation panel can be fixed to each wall surface, or simply disposed without being fixed. The “inner surface” of the front wall 2a, the side wall 2b, the bottom wall 2c, and the lid 3 refers to the surface on the accommodation space 4 side among the front and back surfaces.

  Considering the heat insulation in the accommodation space 4, it is desirable that the vacuum insulation panel is disposed on all the constituent surfaces of the accommodation space 4. However, depending on the use environment, only a part of the constituent surfaces of the accommodation space 4 is vacuum insulated. Panels can also be placed. A part or all of these arranged vacuum heat insulation panels are provided with the temperature sensor 5, whereby the temperature in the accommodation space 4, that is, the environmental temperature of the cold-frozen food F can be detected. For convenience, the vacuum heat insulation panel provided with the temperature sensor 5 is referred to as “vacuum heat insulation panel 6 with sensor”, and the vacuum heat insulation panel without the temperature sensor 5 is referred to as “vacuum heat insulation panel 7”.

(Vacuum insulation panel with sensor)
4A to 4E are cross-sectional views showing the sensor-equipped vacuum heat insulation panel 6. As shown in these figures, the sensor-equipped vacuum heat insulation panel 6 is obtained by attaching a temperature sensor 5 to a vacuum heat insulation panel provided with a core material 8 and a jacket material 9, and FIGS. The vacuum heat insulation panel 6 with a sensor from which the attachment method of the temperature sensor 5 each differs is shown.

The vacuum heat insulation panel is obtained by reducing the pressure in a state where the core material 8 is covered with the jacket material 9 and heat-sealing (heat-sealing) the opening of the jacket material 9. A large number of gaps are provided inside the core member 8, and the air in the gaps is discharged by pushing out the air by the rollers or by sucking air, whereby the inside of the vacuum heat insulating panel is decompressed to be in a vacuum state. At this time, if the core material 8 is damp, it is difficult to maintain the subsequent vacuum state. Therefore, it is desirable to carry out the air discharging operation from the inside of the gap in a dry environment such as sending dry air. Note that the vacuum state here refers to not only an absolute vacuum state but also a state with a high degree of vacuum, including a state close to an absolute vacuum state of 10 ⁻⁵ Pa or less, preferably 10 ^{−5 to} 200 Pa, preferably A state where the degree of vacuum is about 0.1 to 100 Pa is also included.

  The more air that can be discharged from the core material 8 is, the more the pressure is reduced, that is, a vacuum heat insulation panel having a higher degree of vacuum is obtained. Therefore, as the material of the core material 8, a so-called porous body having many voids inside is used. For example, fiber materials such as glass wool, ceramic fiber and rock wool, powder such as powder silica, organic or inorganic foam The body can be used. Styrofoam, FRP, etc. can also be used, but since the heat insulating material can reduce the pressure when it can exhaust a lot of air and can be in a high vacuum state, many voids and holes (hereinafter referred to as “voids”) So-called porous materials having a. Styro homes can also be used as the core material 8, but care must be taken depending on the situation of use because they are easily broken. On the contrary, the glass wool used as the core material 8 has a characteristic that it is difficult to break. The material, shape, size, thickness, etc. of the core material 8 are designed according to the application of the vacuum heat insulating panel 6 with sensor.

  The jacket material 9 can be a film, sheet, or plate. The jacket material 9 needs to be formed of a material rich in gas barrier properties in order to keep the inside in a vacuum state. Materials with excellent gas barrier properties include metals such as stainless steel, aluminum, and iron, plastics (resins), composites made by laminating metal foil and plastic film, composites obtained by depositing metal on plastics, and metal sheets and resin sheets attached. There are composite materials in which a laminated material such as a woven fabric or a non-woven fabric made of resin fiber or natural fiber and a film or sheet made of a gas barrier resin or metal foil are laminated. The material, thickness, shape, size, composite structure, and the like of the jacket material 9 can be appropriately adopted depending on the purpose of use. The envelope material 9 may be a film, a sheet, or a plate. However, one side of the core material 8 is covered with the film-like envelope material 9 and the opposite side surface is a sheet-like envelope. It can also be coated with the material 9. Alternatively, as shown in FIG. 9, a plate-like covering material 9a is arranged on one side (the lower surface in FIG. 9) of the core material 8, and the opposite side surface (upper surface in FIG. 9) of the core material 8 is placed in a film-like or sheet-like outer shape. The core material 8 can also be covered by covering the material 9b. In this way, the core material 8 can be coated by combining film, sheet, and plate shapes. In some cases, a plate-like covering material 9a as shown in FIG. 9 is arranged on both surfaces of the core material 8, and the outer side thereof is further covered with a film-like or sheet-like covering material 9b, and the covering material 9b. The inside can also be evacuated. The material, shape, size, thickness, strength, and the like of the jacket material 9 are also designed in accordance with the application of the vacuum heat insulating panel 6 with a sensor and the vacuum heat insulating panel 7. The covering material 9 can be made of the same or different material and structure (both having gas barrier properties) to cover the core material 8, and the outer cover material 9 can be covered by double covering. Even if the workpiece 9 is damaged, a vacuum state inside the jacket 9 is ensured.

  The covering material 9 using a metal material such as aluminum has a characteristic of high thermal conductivity, but also has shielding properties (radio wave shielding properties). As will be described later, the temperature sensor 5 placed inside the vacuum heat insulation panel detects the ambient temperature, and the detected result is communicated to the outside. Aluminum material is suitable for detecting ambient temperature, but aluminum material is not suitable for communication.

  On the other hand, a nylon-based material can be used as the jacket material 9, but the nylon-based material has a characteristic that it has low thermal conductivity and easily transmits radio waves. In other words, in contrast to aluminum materials, nylon-based materials are suitable for communication, but nylon-based materials are not suitable for detecting ambient temperature. In order to take advantage of both characteristics, an aluminum material and a nylon material can be combined to form the jacket material 9. As an example, the range close to the temperature sensor portion of the wireless sensor 13 (covering the temperature sensor portion) uses an aluminum material having high thermal conductivity, and the range close to the antenna portion of the wireless sensor 13 (covering the antenna portion) is a radio wave. A jacket material 9 made of a nylon material with good permeability can be used.

  The opening of the jacket material 9 is heat-sealed in a state where the air in the gap of the core material 8 has been discharged, that is, in a state where the inside of the vacuum heat insulation panel is decompressed, thereby maintaining a high vacuum state. it can. Therefore, the cover material 9 is often combined with a heat-weldable material. For example, a combination of a PET material and a metal plate such as aluminum, a film, a sheet, etc., such as using a material obtained by superimposing a PET material on the back surface (or front and back surfaces) of an aluminum foil as an outer cover material 9 ( Bonded or vapor-deposited) can be used. The PET material is welded at about 90 ° C., whereas the wireless sensor 13 is normally not melted up to about 200 ° C., which is preferable for the wireless sensor 13.

  In addition, the core material 8 and the jacket material 9 are not limited to those exemplified here, but materials and materials conventionally used as a vacuum heat insulation panel can be used. When the material and thickness are designed to be foldable, the single vacuum heat insulating panel 6 with sensor can be bent and installed in the cold insulation container 1.

  A vacuum heat insulation panel has the heat insulation performance excellent by making the inside into a vacuum state (reduced pressure state). Specifically, the thermal conductivity of the vacuum heat insulation panel is 0.002 to 0.01 w / mk, and compared to 0.02 to 0.03 w / mk of foamed polystyrene and 0.02 w / mk of air, its heat insulation. It can be seen that the performance is remarkable. If the vacuum heat insulation panel which has this outstanding heat insulation performance is utilized, the heat insulation performance of the conventional cold storage container B will improve markedly.

  The sensor-equipped vacuum heat insulation panel 6 includes a temperature sensor 5 and a communication unit (transmission unit) 12 that transmits the temperature data detected here in the outer cover material 9. The temperature data detected by the temperature sensor 5 is wirelessly transmitted from the communication unit 12 to, for example, an external management center or other equipment, and can be processed by the management center or other equipment to perform temperature management from a remote location. The communication can also be performed by wire. In the case of a wireless system, an antenna can be built in or externally attached to the communication unit 12. In the case of a wired system, other connection devices (connectors) such as connectors that can be electrically connected to external devices are provided outside the jacket material 9, and wired communication is performed with the external devices connected thereto. Can do.

  In the present invention, the temperature data detected by the temperature sensor 5 is stored in a data logger (storage unit) provided on the inner side of the jacket material 9, and the stored data is stored in, for example, an external management center or other places. The temperature state can also be managed by processing. The data logger can record not only temperature data but also data detected by other sensors, such as vacuum data, humidity data, acceleration data, and the like. The humidity sensor detects moisture when the gas barrier property of the jacket material 9 is deteriorated or broken and enters the inside of the jacket material 9 from the outside. The acceleration sensor can sense vibration. By providing this acceleration sensor, for example, while the cold food F is being transported in the cold container 1, the vibration state around the cold food F can be grasped, which is more preferable from the viewpoint of quality control.

  The vacuum heat insulating panel 6 with sensor is provided with a battery 13 c for operating the temperature sensor 5 and the communication unit 12, or the data logger and the vacuum sensor 14. The battery can be a long-life battery such as a lithium battery. This 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 9 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.

  The wireless sensor 13 includes the temperature sensor 5, the communication unit 12, and the battery 13c as a unit. The wireless sensor 13 is commercially available and is now widely used. The wireless sensor 13 includes three parts, a main body part 13a having a temperature sensor part (temperature sensor 5) for detecting temperature, an antenna part 13b (communication part 12), and a battery 13c in the form shown in FIG. ing. In addition, the vacuum heat insulation panel 6 with a sensor of this invention should just be equipped with the temperature sensor 5 and the communication part 12 at least, and even if these are separate bodies, they may be integrated like the wireless sensor 13, Hereinafter, for the sake of convenience, the case where the vacuum heat insulating panel 6 with sensor includes a wireless sensor 13 (having three parts of a main body portion 13a, an antenna portion 13b, and a battery 13c) will be described. Further, in recent years, the wireless sensor 13 has been reduced in size and has an outer dimension (length) of 2 to 4 mm. The wireless sensor 13 used for the vacuum heat insulating panel 6 with sensor is preferably smaller, but the vacuum Any size and shape can be designed as long as they can be installed inside the heat insulation panel.

  Although the radio | wireless sensor 13 used for the vacuum heat insulation panel 6 with a sensor may be separately produced as an exclusive thing, what is marketed can also be used. In addition to the temperature sensor that can detect the temperature, some commercially available wireless sensors 13 include a humidity sensor that can detect humidity and an acceleration sensor that can detect the degree of vibration. Therefore, such a wireless sensor can also be used.

  A lithium battery or the like is frequently used for the battery 13c of the wireless sensor 13. Lithium batteries and the like are generally known to easily deteriorate in a low-temperature environment or a high-humidity environment, and the lifetime is extremely shortened. For this reason, the wireless sensor 13 is often used in an environment where the temperature is normal and the humidity is not high. Therefore, if the wireless sensor 13 can be installed in the cold storage container 1 that transports the cold food F, it is preferable that the environmental temperature of the cold food F can be managed even during the transportation, Since the dry ice D or the like is placed, a problem of deterioration (short life) of the battery 13c occurs, and the wireless sensor 13 has not been installed in the cold storage container 1 conventionally. On the other hand, in the present invention, since the wireless sensor 13 is installed inside the vacuum heat insulation panel having high heat insulation performance, it becomes possible to protect the battery 13c from low temperature and high humidity in the accommodation space 4, and there is a problem of deterioration of the battery 13c. Since it does not occur, the wireless sensor 13 can be provided in the cold insulation container 1 with peace of mind.

  Various methods can be selected as a method of installing the wireless sensor 13 inside the vacuum heat insulating panel, and examples thereof are shown in FIGS.

  FIG. 4A is a cross-sectional view showing a case where the wireless sensor 13 is embedded in the core material 8. As shown in this figure, the wireless sensor 13 can be installed in the embedded recess 10 provided in the core member 8. Alternatively, any one of the three parts of the main body part 13a, the antenna part 13b, and the battery 13c can be installed in the embedded concave part 10, or two parts selected from these three parts can be installed in the embedded concave part 10. It can also be installed. In this case, an embedded recess 10 is provided in the core material 8 in advance, and a wireless sensor 13 (or at least one of the three components) is installed on the core material 8, and then the envelope material 9 is put over to reduce the pressure. The vacuum insulation panel 6 with sensor is completed by heat-sealing the opening of the material 9. The void formed in the embedded recess 10 after the wireless sensor 13 (or at least one of the three components) is installed is injected with a highly heat-conductive filler before covering the outer cover material 9. Or it can be left as a void. When the battery 13c is installed in the embedded recess 10, the battery 13c is disposed at substantially the center of the core member 8, so that it is reliably protected from the external low-temperature / high-humidity environment.

  FIG. 4B is a cross-sectional view showing a case where the wireless sensor 13 is arranged on the surface of the core material 8. As shown in this figure, a wireless sensor 13 can be installed between the core material 8 and the jacket material 9. In this case, the wireless sensor 13 is attached to the surface of the core material 8 (upper surface in the drawing) in advance, and then the outer cover material 9 is covered and decompressed, and the opening of the outer cover material 9 is heat-sealed, whereby a vacuum with a sensor is provided. The heat insulation panel 6 is completed. Since the main body portion 13a and the antenna portion 13b are covered only with the jacket material 9, it is preferable in terms of temperature detection and communication. Since the vacuum heat insulating panel 6 with the sensor has the battery 13c near the surface, the surface (the lower surface in the figure) where the battery 13c is not disposed becomes a low temperature / high humidity environment (specifically, the storage of the cold container 1). It is desirable to arrange and use it so as to be on the space 4 side.

  FIG. 4C is a cross-sectional view showing a case where the main body portion 13 a and the antenna portion 13 b of the wireless sensor 13 are embedded in the surface of the core material 8 and the battery 13 c is embedded in the core material 8. In this case, the battery 13 c is embedded in a part of the core material 8 in advance, the main body portion 13 a and the antenna portion 13 b are attached to the surface of the core material 8, and then the outer cover material 9 is covered to reduce the pressure. The vacuum insulation panel 6 with sensor is completed by heat-sealing the opening. Since the main body portion 13a and the antenna portion 13b are covered only with the jacket material 9, it is preferable in terms of temperature detection and communication. Moreover, since the battery 13c is disposed inside the core member 8, it can be protected from an external low-temperature / high-humidity environment. In the vacuum heat insulating panel 6 with a sensor in this figure, the surface (the lower surface in the figure) where the battery 13c is not disposed is a low temperature / high humidity environment (specifically, the storage space 4 side of the cold storage container 1). It is desirable to arrange and use them.

  In FIG. 4D, the antenna unit 13 b and the battery 13 c of the wireless sensor 13 are arranged on one surface of the core member 8, and the temperature sensor 5 at the tip of the main body unit 13 a is arranged on the other surface of the core member 8. It is sectional drawing which shows the case where it did. In this case, the antenna portion 13b and the battery 13c are installed on one surface (upper surface in the drawing) of the core member 8, and the temperature sensor 5 at the tip of the main body portion 13a is connected to the other surface (lower surface in the drawing). The sensor-equipped vacuum heat insulation panel 6 is completed by disposing the cover material 9 and then reducing the pressure by covering the cover material 9 and heat-sealing the opening of the cover material 9. The temperature sensor 5 at the tip of the main body 13a can be extended to the opposite surface by passing through a through hole or through groove provided in the core member 8.

  FIG. 4 (e) shows that the antenna unit 13 b and the battery 13 c of the wireless sensor 13 are arranged on one surface of the core member 8, and the temperature sensor 5 at the tip of the main body unit 13 a is arranged on the other surface of the core member 8. It is sectional drawing which shows the case where it did. In this case, the battery 13c is embedded in the vicinity of one surface (upper surface in the drawing) of the core member 8 and the antenna portion 13b is installed, and the temperature sensor 5 at the tip of the main body portion 13a is connected to the other surface (see FIG. Then, the vacuum insulation panel 6 with sensor is completed by placing the outer cover material 9 and then reducing the pressure by covering the outer cover material 9 and heat-sealing the opening of the outer cover material 9. The temperature sensor 5 at the tip of the main body 13a can be extended to the opposite surface by passing through a through hole or through groove provided in the core member 8.

  The vacuum heat insulating panel 6 with a sensor shown in FIGS. 4D and 4E is preferable in terms of communication because the antenna portion 13b is covered only with the jacket material 9. Further, since the battery 13c is disposed on the surface of one core material 8 (or in the vicinity of the surface) and the temperature sensor 5 is disposed on the surface of the other core material 8, for example, the temperature sensor 5 It is preferable to arrange and use a certain surface (the lower surface in the figure) so as to be on the side of the storage space 4 of the cold container 1 in terms of temperature detection, and also in terms of protecting the battery 13c from a low temperature / high humidity environment. Is preferred.

  When temperature detection by the temperature sensor 5 and communication by the antenna unit 13b are considered, selection of the material of the jacket material 9 used in the vicinity of the temperature sensor 5 and the antenna unit 13b at the tip of the main body 13a is important. As described above, metal materials such as aluminum have high thermal conductivity, while they have shielding properties (radio wave shielding), while nylon materials have low thermal conductivity and do not emit radio waves. It has the characteristic of being easily transmissive. Therefore, in the case of the sensor-equipped vacuum heat insulation panel 6 shown in FIGS. 4D and 4E, the surface on which the antenna portion 13b is disposed (upper surface in the drawing) uses a radio wave-transmitting nylon material, and the temperature sensor. The surface on which 5 is disposed (the lower surface in the figure) is preferably an outer cover material 9 made of a metal material having high thermal conductivity.

  In the case of the vacuum heat insulating panel 6 with a sensor shown in FIGS. 4A to 4C, the entire material is made of a metal material having high thermal conductivity, and a nylon-based material that is partially radio wave-transmitting as long as it covers the antenna portion 13b. It can also be set as the jacket material 9 using a raw material. Alternatively, it is also possible to use a nylon material that is radio wave permeable as a whole, and a jacket material 9 that uses a metal material that is partially high in thermal conductivity within a range that covers the temperature sensor 5. If the material is partially different (the entire material is made of metal and partly nylon material, or vice versa), a different material part may be provided so as to form a hole or groove including the part. it can.

  In addition to the temperature sensor 5 (or the wireless sensor 13), the vacuum heat insulating panel 6 with sensor can also include a vacuum sensor 14. This vacuum sensor 14 can detect the vacuum state inside the jacket material 9, and there are various types such as a Pirani vacuum gauge, a diaphragm vacuum gauge, a capacitance type vacuum sensor, a micro mechanical vacuum sensor, etc. The vacuum sensor can be used. Since the vacuum state means a reduced pressure state, for example, a pressure sensor can be used. In order to accommodate in the core member 8 or the jacket member 9, it is desirable to select a small and thin vacuum sensor 14 if possible.

  In FIG. 10, the vacuum sensor 14 is operated by a power source supplied from the battery, the pressure inside the jacket material 9 is detected by the vacuum sensor 14, and the detected current (voltage) is amplified by the amplifier A. By comparing the output voltage with the appropriate vacuum state (appropriate pressure in the jacket material 9: reference pressure) Pa required by the sensor-equipped vacuum insulation panel 6 in the comparator C, the inside of the jacket material 9 is appropriate. It can be determined whether or not the vacuum state is maintained. In FIG. 10, the detected pressure is displayed on the digital meter 15 so that the vacuum state inside the jacket material 9 can be confirmed. When the output of the comparator C is higher than the reference pressure Pa, the electromagnetic valve of the vacuum pump P can be opened by the relay 16 and the inside of the jacket material 9 can be decompressed by the vacuum pump P. The vacuum sensor 14 may be entirely provided in the jacket material 9, but may be partially attached to the exterior of the jacket material 9. In either case, it is attached so that the vacuum state in the jacket material 9 is not impaired. The detection data of the vacuum sensor 14 in FIG. 10 can also be transmitted to the amplifier A via a communication unit provided in the sensor-equipped vacuum heat insulation panel 6.

  The vacuum sensor 14, the temperature sensor 5, the communication unit 12, and the data logger can be individually provided inside the core material 8 and the jacket material 9. It is easy to accommodate in the material 9.

(Arrangement of vacuum insulation panel with sensor)
As described above, all or a part of the constituent surface of the storage space 4 of the cold insulation container 1 is configured by the sensor-equipped vacuum heat insulation panel 6 and the vacuum heat insulation panel 7. For example, as shown in FIGS. 1 and 3, the inner surface of the side wall 2b is a vacuum heat insulating panel 6 with a sensor on which the wireless sensor 13 is installed, and the inner surface of the front wall 2a, the bottom wall 2c, and the lid 3 is the inner surface of the wireless sensor 13. There can be no vacuum insulation panel 7. Or the vacuum heat insulation panel 6 with a sensor can be arrange | positioned to the inner surface of the bottom wall 2c and the lid | cover 3, and the vacuum heat insulation panel 7 can also be arrange | positioned to the inner surface of the front wall 2a and the side wall 2b. In short, at least one of the two surfaces of the front wall 2a, one of the two surfaces of the side wall 2b, the bottom wall 2c, and the inner surface of the lid 3 is vacuum insulated with a sensor. If the panel 6 is arrange | positioned, the vacuum heat insulation panel 6 with a sensor and the vacuum heat insulation panel 7 can be made into arbitrary combinations. In addition, although it is desirable to arrange | position the vacuum heat insulation panel 7 all on the inner surface which does not arrange | position the vacuum heat insulation panel 6 with a sensor, arrangement | positioning of the vacuum heat insulation panel 7 can also be partially omitted.

  When the sensor-equipped vacuum heat insulation panel 6 is disposed on the “construction surface of the housing space 4”, it is desirable to have the arrangement as illustrated in FIG. 3. That is, it is preferable to detect the temperature when the temperature sensor 5 at the tip of the main body portion 13a is positioned close to the accommodation space 4, and is located on the back side of the side wall 2b and the like when viewed from the accommodation space 4. It is preferable that the battery 13c is disposed in the space (so that a heat insulating panel is interposed between the housing space 4 and the battery 13c) in that the battery 13c is protected from a low temperature / high humidity environment. In addition, as shown in FIG. 3 (FIG. 7 and FIG. 8 are also the same), the antenna part 13b of the vacuum heat insulation panel 6 with a sensor passes through the through-hole and the through-groove provided in the core material 8, and is on the opposite side. It can also extend to the surface (in FIG. 3, the accommodation space 4 side). Of course, the antenna portion 13b may not be extended to the opposite side, and the entire antenna portion 13b may be disposed on the same surface of the core member 8 as shown in FIGS.

  Among existing cold storage containers currently in circulation, there is a type in which dry ice D or the like is accommodated in the lid 3 as shown in FIG. The cold insulation container 1 of the present invention can also be created by arranging the sensor-equipped vacuum heat insulation panel 6 and the vacuum heat insulation panel 7 using such a type of existing cold insulation container. In this case, the sensor-equipped vacuum heat insulation panel 6 disposed on the inner surface of the lid 3 is desirably disposed such that the battery 13c is on the accommodation space 4 side. Thereby, the vacuum heat insulation panel 6 with a sensor can protect the battery 13c from the low temperature and high humidity environment by the dry ice D in the lid | cover 3 or a cool storage agent, and is suitable.

Hereinafter, an example is shown about the case where the cold-reserved food F is delivered using the cold-reserving container 1 of the present invention.
When an order is received from the consumer, the designated cold insulated food F is taken out from the freezer or refrigerator. The cold-reserved food F in a low-temperature state is put in the storage space 4 of the cold-reserving container 1 together with the dry ice D, and the lid 3 is fitted.
The cold container 1 containing the cold food F is mounted on a transport vehicle and delivered to a consumer. During delivery, the cold insulated food F in the accommodation space 4 can maintain a low temperature state for a long time due to the excellent heat insulating performance of the vacuum heat insulating panel 6 with sensor.
In addition, the temperature in the accommodation space 4 is detected in the respective conditions when being accommodated in the cold container 1, during conveyance, at the conveyance destination, and the detected temperature is transmitted by the antenna unit 13 b, for example, away from the quality control center or the like Since the detected temperature can be received at the place, the temperature control of the conveyed food can be easily performed.

[Other Embodiments]
Another embodiment of the cold insulation container of the present invention will be described with reference to FIGS. FIG. 7 is a sectional view of the cold insulation container 1 in which the reinforcing material 11 is combined with the vacuum insulating panel 6 with sensor as viewed from the front, and FIG. 8 is a wall material in which the vacuum insulating panel 6 with sensor is incorporated in the insulating material. It is sectional drawing which looked at the comprised cold storage container 1 from the front.

  The cold insulation container 1 of the present invention is formed by arranging a vacuum insulation panel 6 with a sensor or a vacuum insulation panel 7 on the inner surface of a cold insulation container B that is currently used, or a newly created container body 2 and lid 3. However, the container main body 2 may be formed by the vacuum heat insulating panel 6 with sensor or the vacuum heat insulating panel 7 itself, and the lid 3 may be formed by the vacuum heat insulating panel 6 with sensor or the vacuum heat insulating panel 7. That is, the sensor-equipped vacuum heat insulation panel 6 or the vacuum heat insulation panel 7 is directly used as the front wall 2 a, the side wall 2 b, and the bottom wall 2 c, and the lid 3. In this case, all can be made into the vacuum heat insulation panel 6 with a sensor, or only a part can be made into the vacuum heat insulation panel 6 with a sensor, and others can be made into the vacuum heat insulation panel 7, and the arrangement and combination are arbitrarily designed. it can. Further, for the purpose of reinforcing the strength of the cold insulation container 1, as shown in FIG. 7, a reinforcing material 11 can be attached to the outer periphery of the container body 2 formed of the vacuum heat insulating panel 6 with a sensor or the vacuum heat insulating panel 7. . Similarly, the lid 3 formed by the sensor-equipped vacuum heat insulation panel 6 or the vacuum heat insulation panel 7 can also be reinforced by the reinforcing material 11.

  Or the container main body 2 and the lid | cover 3 can also be formed with the vacuum heat insulation panel 6 with a sensor shown in FIG. 9 (or vacuum heat insulation panel 7) itself (FIG. 11). The vacuum heat insulating panel 6 with a sensor shown in FIG. 9 accommodates the wireless sensor 13 in an embedded recess 10 provided in the core material 8, and a plate-shaped metal jacket material 9 a is disposed on the back surface of the core material 8. The core material 8 is covered with a resin sheet covering material 9b, the sheet-shaped covering material 9b is brought into close contact with the plate-shaped metal covering material 9a, and the plate-shaped metal covering material 9a and the sheet The inside of the outer casing material 9b is evacuated to a vacuum state. Alternatively, although not shown, instead of the resin sheet covering material 9b shown in FIG. 9, a plate-shaped metal covering material 9a is installed on the upper surface of the core material 8, that is, the core material 8 is formed into a plate-shaped metal from above and below. After sandwiching between the outer covering materials 9a and sealing between the outer covering materials 9a, the inside can be decompressed to be in a vacuum state.

  Thus, when forming the container main body 2 or the lid 3 by the vacuum heat insulating panel 6 with the sensor or the vacuum heat insulating panel 7 itself, the front wall 2a, the side wall 2b, the bottom wall 2c, and the lid 3 were independently created. Can be assembled later. Alternatively, the container body 2 can be formed by bending the five vacuum heat insulating panels 6 with sensors and the vacuum heat insulating panel 7 continuously formed in a cross shape (plus symbol shape). The cold insulating container 1 (that is, the container main body 2 with the lid 3) can also be created by bending the six vacuum insulating panels 6 with sensors and the vacuum insulating panel 7. In addition, the container main body 2 and the cold storage container 1 created by the method shown here can of course be used as they are, or can be installed and used in an existing container.

  Moreover, as shown in FIG. 8, the cold insulation container 1 of this invention embeds the vacuum heat insulation panel 6 with a sensor or the vacuum heat insulation panel 7 in the container body 2 and the lid 3 which are newly produced at the time of the production. It can also be formed by placing (incorporating). That is, the cold insulation container 1 is completed by using the front wall 2a, the side wall 2b, the bottom wall 2c, the lid 3, and the members with the vacuum heat insulation panel 6 with sensor or the vacuum heat insulation panel 7 built in in advance. In this case, it is possible to arbitrarily design which member incorporates the vacuum heat insulating panel 6 with sensor and which member incorporates the vacuum heat insulating panel 7.

  In addition, when the front wall 2a, the side wall 2b, the bottom wall 2c, and the lid 3 are formed of foamed polystyrene or the like, a fitting concave portion in which the sensor-equipped vacuum heat insulation panel 6 or the vacuum heat insulation panel 7 can be fitted is provided. The container main body 2 and the lid 3 can be formed by installing the vacuum heat insulating panel 6 with a sensor or the vacuum heat insulating panel 7 in the joint recess.

  The cold storage container of the present invention can be applied not only for the delivery of foodstuffs but also for the transportation of cosmetics and medicines.
