Description

Delivery method of frozen goods

  The present invention relates to a method for delivering frozen goods, and more particularly to a small-lot delivery method for delivering frozen goods from a wholesaler or the like to a plurality of markets.

  In recent years, with the spread of frozen foods and the like, the delivery of frozen products that require cold storage is increasing. Such delivery is generally performed by dividing into large-volume delivery from a factory of frozen goods to a wholesaler (distribution center) and small-scale delivery from a wholesaler to a supermarket or a convenience store.

  By the way, in small-lot delivery in which frozen goods are delivered from a wholesaler to a market, a convenience store, etc., the frozen goods are distinguished for each delivery destination and stored in a cool container.

  2. Description of the Related Art Conventionally, as a cold container, a container that uses a simple heat insulating material such as foamed polystyrene or rigid foamed urethane foam and opens and closes a lid using a chuck, a hook-and-loop fastener, or the like is often used. However, such a cold storage container has a high initial thermal conductivity of the heat insulating material and is inferior in the cold storage performance, and is also apt to be bulky in transportation and storage after delivery. For this reason, a foldable cold storage container with improved cold storage performance has been developed (see Patent Document 1).

  FIG. 19 is a perspective view showing the cold insulation container 100 disclosed in Patent Document 1. FIG. The cold insulation container 100 disclosed in Patent Document 1 includes an outer bag 101 and an inner bag 103 having flexibility, and a vacuum heat insulating panel 102. The outer bag 101 has a bottom surface and five side surfaces that are sewn in a substantially rectangular parallelepiped shape, and a belt 105 is hung from the side surface to the opposite side surface through the bottom surface. A lid 104 is sewn on the upper side of the outer bag 101, and a vacuum heat insulation panel (not shown) is provided in advance in the bottom of the outer bag 101 and the inside of the lid 104.

  In use, four heat insulation panels 102 are inserted along the four side surfaces of the outer bag 101, and the surface fasteners 111 of the heat insulation panel 102 are engaged with the surface fasteners 110 of the outer bag 101. Further, the inner bag 103 is inserted into the outer bag 101 on which the heat insulating panel 102 is mounted, and the surface fastener 112 of the inner bag 103 is engaged with the surface fastener 111 of the heat insulating panel 102 for assembly.

  The frozen bag or the like is stored in the inner bag 103 of the assembled cold storage container 100, the cover 104 is covered with the outer bag 101, and the surface fasteners 106 and 108 of the cover 104 are connected to the surface fastener 107 of the outer bag 101, Each is engaged with 109 and closed for delivery.

  Further, the cold insulation container 100 disclosed in Patent Document 1 can be folded when not in use. In other words, when not in use, the inner bag 103 and the four heat insulation panels 102 are removed from the outer bag 101 and the heat insulation panel 102 and the folded inner bag 103 removed are removed from the outer bag 101, contrary to when assembling. Store. Then, the outer bag 101 is folded while being overlapped with the lid portion 104 facing the bottom surface, and the belt 105 is folded over both ends of the belt 105.

  That is, the cold storage container 100 disclosed in Patent Document 1 is used for cold storage and delivery of frozen products as a box having heat insulation properties when used, and can be folded and transported and stored when not in use without being bulky. is there.

  By the way, delivery vehicles used for delivery of food and the like are roughly classified into a freezer car, a refrigerated car, a cold car, and a normal temperature car.

  In addition, some delivery vehicles can be equipped with a freezer / refrigerator equipped with both a freezer and a refrigerator in a single vehicle, and the temperature of a single storage can be switched between freezer and refrigerator. There are also vehicles that can handle all delivery.

However, a vehicle having such a composite function is not common, and when delivering frozen products, the frozen products are stored in a cold storage container in which a cold storage agent is inserted, and then the cold storage container is used as a refrigerator vehicle. It is customary to be delivered.

  However, as described above, when a frozen product is delivered, it is delivered using a refrigeration vehicle after being stored in a cold storage container into which a cold storage agent is inserted. For this reason, even when a small amount of frozen goods is delivered, one refrigeration vehicle is occupied, which has been a factor that hinders cost savings.

  In other words, since the freezing vehicle requires low temperature management, the delivery cost is higher than that of a refrigerated vehicle, a cold storage vehicle, and a normal temperature vehicle. Moreover, the delivery cost of the vehicle having the above-described combined function becomes higher. For this reason, when one refrigeration vehicle is occupied in order to deliver a small amount of frozen goods, there was a dislike for an increase in delivery cost.

  Further, even when the frozen product and the refrigerated product are delivered to the same delivery destination, they cannot be delivered together due to the different cold temperatures, and a dedicated delivery vehicle is required for each product. For this reason, the number of vehicles required for delivery has increased and the delivery cost has increased, and improvements have been desired in terms of environmental measures.

  Furthermore, in relation to the delivery of the frozen product described above, when the frozen product is delivered to the delivery destination, the cold storage container containing the frozen product is once delivered to the delivery destination as it is, and the previous cold storage is provided for the later delivery. A method of collecting the container may be employed.

  In this case, if the cold storage container 100 disclosed in Patent Document 1 is used, the cold storage container can be folded and stored after taking out the frozen product from the cold storage container in accordance with the work of the delivery destination. Good. However, as described above, the cold storage container 100 disclosed in Patent Document 1 requires a great deal of time for folding, and is often left without being folded as it is, so that the folding effect cannot be exhibited. .

  The present invention is proposed in view of the above circumstances, and the conventional delivery method for frozen products has been reviewed, and the frozen product has achieved reasonable cost savings and improved work efficiency while maintaining the quality of the frozen product. The purpose is to provide a delivery method.

  In order to achieve the above object, the present invention stores a frozen product that needs to be kept cool in a cold storage container constituted by using a vacuum heat insulating material, and the cold storage container is a refrigeration vehicle, a cold storage vehicle, or a room temperature vehicle other than a freezing vehicle. It is loaded on and delivered.

  Here, the cold storage vehicle refers to a vehicle in which a side surface, a ceiling, a floor, and a door of the storage are formed using a heat insulating material in order to thermally shield the inside of the storage from the outside. In addition, a freezer car is a vehicle that exclusively transports frozen foods such as frozen meats and ice cream while maintaining quality, and the inside temperature of the storage is controlled within the range of −25 ° C. to −10 ° C. by the cold car. It refers to a vehicle equipped with a possible refrigeration system. A refrigerated vehicle is a vehicle that exclusively transports chilled foods such as fresh food and dairy products, or refrigerated foods such as fresh vegetables and confectionery, while maintaining the quality. It refers to a vehicle equipped with a refrigeration apparatus that can be controlled within a range of ˜ + 20 ° C., and so-called chilled vehicles are included in the category of refrigerated vehicles. In addition, the normal temperature vehicle refers to a vehicle including a normal storage without heat insulation.

  According to the present invention, by using a vacuum heat insulating material, the heat insulating property of the cold insulation container can be made extremely high. Therefore, by storing the frozen product in the cold insulation container and blocking the heat conduction with the surroundings, Can suppress the temperature fluctuation of the frozen food within a predetermined range. Therefore, it is possible to deliver a frozen product using a refrigerated vehicle, a cold storage vehicle, or a room temperature vehicle other than the refrigerator vehicle without using a refrigerator vehicle. Along with this, a refrigerator truck is not required for delivery of frozen goods, and the delivery cost can be reduced.

  In addition, since frozen products stored in cold storage containers are delivered using refrigerated vehicles, cold storage vehicles, or normal temperature vehicles other than frozen vehicles, frozen products can be loaded at the same time in addition to delivery products originally loaded on vehicles used for delivery. Can be delivered. In other words, when delivering using a refrigerated vehicle, in addition to the refrigerated product originally loaded on the refrigerated vehicle, frozen products can be loaded and delivered simultaneously. Moreover, when delivering using a cold storage vehicle, in addition to the cold storage products originally loaded on the cold storage vehicle, frozen products can be loaded and delivered simultaneously. Furthermore, when delivering using a normal temperature car, in addition to the goods originally loaded on the normal temperature car, frozen goods can be simultaneously loaded and delivered.

  As a result, the frozen product and any product other than the frozen product can be delivered together to the same delivery destination with one delivery vehicle, and the delivery efficiency is significantly improved. In addition, since a single delivery vehicle can deliver frozen products and any product other than frozen products together, there is no need for a freezing vehicle to deliver only frozen products, reducing the number of vehicles required for delivery, It can contribute to environmental protection.

  In this invention, the time which can be delivered, maintaining the quality (temperature) of the frozen goods accommodated in the cold storage container, changes with the storage ratio of frozen goods, and the kind of delivery vehicle. In other words, the delivery time while maintaining the quality of the frozen product stored in the cold storage container varies depending on the amount of the frozen product stored in the cold storage container and whether the refrigerator car, the cold storage car, or the normal temperature car is used. .

  Therefore, by conducting a test in advance for each type of vehicle to be delivered and finding the time that can be delivered while maintaining the quality of the frozen product with respect to the storage rate of the frozen product, the delivery vehicle can be easily adapted to the time required for delivery. The quality of frozen products is not impaired.

  Recently, some freezer and refrigerated vehicles employ an automatic idling stop. In addition, the driver may voluntarily encourage idling stop. The automatic idling stop vehicle is, for example, a vehicle having a structure in which the engine is automatically stopped when the vehicle is stopped and the transmission is in the neutral position, and the engine is automatically started when the clutch is stepped on the start.

  However, in refrigeration vehicles and refrigeration vehicles that employ such an idling stop, the driving of the refrigeration system stops as the engine stops. For this reason, when the temperature inside the freezer or refrigerator is likely to fluctuate and is stored and delivered in a cold insulation container with low heat insulation, the idling stop is adopted in spite of the fact that it is a freezer. The quality of the product may be impaired.

  However, according to the present invention, the heat insulating property is remarkably high by using the vacuum heat insulating material for the cold container. This makes it possible to deliver a frozen product stored in a cold storage container by a vehicle other than the refrigerator vehicle instead of delivering it by a refrigerator vehicle. Therefore, the temperature fluctuation inside the refrigerator due to the idling stop has little influence on the temperature fluctuation inside the cold container, and the frozen goods are prevented from being affected.

  According to the present invention, among the regenerators having a melting point of −27 ° C. or higher and −18 ° C. or lower according to the set temperature of the freezer warehouse, the regenerator having a melting point higher than the set temperature of the freezer warehouse is stored in the freezer warehouse. It is possible to change the phase to a solid simply. This makes it possible to immediately store the cool storage agent in the cold storage container for delivery.

  A tenth aspect of the present invention is the method for delivering frozen goods according to any one of the first to ninth aspects, wherein the vacuum heat insulating material covers the core material obtained by compression-molding the fiber material with a jacket material having gas barrier properties. The interior covered with the jacket material is decompressed and sealed in a vacuum.

  According to the present invention, the heat insulating property can be remarkably improved as compared with the conventional heat insulating material. Thereby, even when using a thin vacuum heat insulating material, it is possible to ensure the necessary cold insulation performance, in the case of cold insulation containers having the same heat insulation and the same internal capacity, when using other heat insulation material with low heat insulation It becomes possible to form it more compactly.

  The invention according to claim 11 is the method for delivering frozen goods according to any one of claims 1 to 10, wherein the vacuum heat insulating material has a thickness of 2 mm or more and 20 mm or less.

  If the thickness of the vacuum heat insulating material is less than 2 mm, the rigidity and strength are low even when necessary cold insulation performance is obtained, and damage is likely to occur due to external force. When the thickness of the vacuum heat insulating material exceeds 20 mm, the cold insulation performance is unnecessarily improved, which becomes a factor that hinders the compactness and cost saving of the cold insulation container. A vacuum heat insulating material having a thickness in the range of 2 mm to 20 mm is preferable, and a thickness of about 10 mm is optimal from the viewpoint of cold insulation performance, compactness, and cost saving.

  The invention according to claim 12 is the method for delivering frozen goods according to any one of claims 1 to 11, wherein the vacuum heat insulating material has an initial thermal conductivity of 0.01 W / mK or less. ing.

  According to the present invention, the heat insulation can be remarkably improved by using a vacuum heat insulating material having a thermal conductivity (initial heat conductivity) in the above range. Therefore, it is possible to reduce the thickness of the heat insulating material, and it is possible to reduce the size of the cold insulation container while ensuring the necessary cold insulation performance.

  The thermal conductivity (initial thermal conductivity) of the vacuum heat insulating material is preferably 0.01 W / mK or less. However, when the cold insulation performance is improved or the thickness is reduced, the thermal conductivity is 0.006 W / mK or less. Desirably, 0.003 W / mK or less is optimal.

  According to a thirteenth aspect of the present invention, in the frozen merchandise delivery method according to any one of the first to twelfth aspects, the cold storage container stores a frozen merchandise of a predetermined ratio or more with respect to the internal volume, The average temperature can be maintained at 0 ° C. or lower for 2 hours or longer.

  Here, as described in the description of the first aspect, the time that can be delivered while maintaining the quality of the frozen goods stored in the cold container varies depending on the delivery vehicle. Moreover, the quantity of the frozen goods accommodated in a cold storage container also affects the temperature in a cold storage container.

  According to the present invention, for each vehicle type used for delivery, the storage rate of frozen products that can keep the average temperature inside the cold storage container at 0 ° C. or lower continuously for 2 hours or more is obtained in advance, and the data is referred to. Thus, it is possible to select a deliverable vehicle type according to the amount of frozen goods to be delivered.

  Thereby, it becomes possible to perform delivery for a short time of about 2 hours, without using a cool storage agent and without impairing the quality of frozen goods.

  The invention according to claim 14 is the method for delivering frozen goods according to any one of claims 1 to 13, wherein the cold storage container contains at least 1 kg of a regenerator per 50 liters of internal volume, The internal average temperature can be maintained at 0 ° C. or lower for 10 hours or longer.

  Here, a limiter device of 90 km / h is attached to a delivery refrigeration vehicle or the like to prevent accidents. For this reason, when delivering from a frozen goods factory to a wholesaler using a highway, time required for delivery increases compared with the case where the limiter device is not attached. For example, if delivery is to be made between Kyushu and Tokyo using an expressway, the time required for a limiter-equipped vehicle will increase by about 3 hours compared to a vehicle without a limiter. Therefore, if a long-distance delivery between Kyushu and Tokyo is performed using a refrigerated vehicle, a delivery time of about 10 hours is required.

  For this reason, in the cold insulation container with low heat insulation, the necessary amount of the cold storage agent increases unnecessarily, and the storage space for the frozen goods that should be originally stored in the cold insulation container is deprived.

  According to the present invention, since a heat insulating material is used for the cold container, the heat insulating property is extremely high. Therefore, by adjusting the structure and thickness of the vacuum heat insulating material to appropriately set the heat insulating property, at least 1 kg of the regenerator per 50 liters of internal volume is stored, and the average of the inside is continuously maintained for 10 hours or more. The temperature can be maintained below 0 ° C.

  Thus, only by storing a small amount of the cold storage agent inside the cold storage container, it becomes possible to deliver for a long time without impairing the quality of the frozen product using a delivery vehicle other than the freezing vehicle.

  According to a fifteenth aspect of the present invention, in the frozen merchandise delivery method according to any one of the first to fourteenth aspects, the cold storage container has an internal volume of 70 liters or more.

  According to the present invention, frozen products destined for one delivery destination are collectively stored in one cold storage container by appropriately setting the internal volume according to the amount of the frozen goods sorted for each small delivery destination. And the delivery work can be made more efficient.

  The internal volume of the cold container is preferably 70 to 100 liters. If the internal volume is less than 70 liters, the internal volume is small, so that the number of cold containers addressed to one delivery destination increases, and storage and delivery operations are troublesome. When the internal volume exceeds 100 liters, the weight when the frozen goods are fully loaded increases and the delivery efficiency decreases. The inner volume of the cold container is optimally 70 to 100 liters.

  The invention according to claim 16 is the method for delivering frozen goods according to any one of claims 1 to 15, further comprising a protective container for storing the cold insulation container, wherein the cold insulation container is accommodated in the protective container. It is supposed to be delivered.

  It is possible to obtain the strength and rigidity of the cold storage container by configuring the cold storage container using a vacuum heat insulating material having predetermined strength and rigidity. However, there is a possibility that the vacuum heat insulating material may be damaged due to excessive external force applied to the cold storage container during delivery. In addition, the strength is insufficient when cooling containers are stacked in multiple stages during delivery.

  According to the present invention, by storing the cold storage container in the protective container, no external force is directly applied to the cold storage container, and damage to the cold storage container is prevented.

  Further, even when the cold storage containers are stored in the protective containers and stacked in multiple stages, the weight on the upper side is supported by the protective containers, and no load is directly applied to the cold storage containers. Thereby, it is possible to prevent breakage of the cold container. In this case, it is possible to efficiently perform the loading operation by adopting a structure in which the protective containers are stacked and engaged.

  The protective container is lightweight and can be provided with sufficient strength and rigidity by being made of a synthetic resin molded product or the like. Further, by making the protective container foldable, collection after delivery can be easily performed, and storage space is also reduced.

According to a seventeenth aspect of the present invention, in the frozen merchandise delivery method according to any one of the first to sixteenth aspects, the cold insulation container includes four peripheral wall portions, a bottom surface portion, and an openable / closable lid portion. Each of the parts is composed of a vacuum heat insulating material connected to each other, and the vacuum heat insulating material covers a board-shaped core material with a gas barrier and flexible outer covering material, and the outer covering material The vacuum heat insulating material is a portion where no core material is present between the outer jacket materials, and the sealing portions where the outer jacket materials are welded to each other, And a bent portion provided in at least one of the connecting portions, and when storing frozen goods in the cold storage container, a box is formed by the respective portions, and the cold storage container is empty. When connecting to the connecting part and the bent part of each part Than is to collect or store folded and bent me.

  According to the present invention, the peripheral wall portion, the bottom surface portion, and the lid portion are all constituted by the vacuum heat insulating materials connected to each other. Therefore, high cold insulation performance is realized, material cost is low, wall thickness is thin, volumetric efficiency is high, and the cold insulation container can be made compact when folded. Assembling and folding can be easily performed in a short time without the need for removing the member. Thereby, delivery work can be performed efficiently and transportation and storage after use are also easy.

  Moreover, since the cold insulation container of this invention is comprised with the vacuum heat insulating material, the intensity | strength and rigidity of each surface are high, and the intensity | strength and rigidity at the time of assembling and making it a box body improve.

  In the present invention, a laminate film in which a heat-welded layer is laminated on the inner surface side of the gas barrier layer and a protective layer is laminated on the outer surface side can be used as the jacket material of the vacuum heat insulating material.

  In other words, a metal foil such as aluminum or a metal or non-oxide-deposited film is used as the gas barrier layer for the vacuum insulation material, and a film such as unstretched polypropylene is provided on the inner surface side of the gas barrier layer. A laminate film in which a film such as nylon or polyethylene terephthalate is laminated as a protective layer on the outer surface side of the gas barrier layer can be used while being laminated as a heat welding layer.

  By employing the jacket material having this configuration, the bag breaking property can be improved while ensuring the gas barrier property and flexibility of the jacket material.

  In the present invention, the core material of the vacuum heat insulating material may be at least any one of a fiber material, a resin foam material, and a granular material.

  When a fiber material is employed as the core material, it is preferable that the fiber elements of the fiber material are aligned and oriented so as to intersect with the thickness direction of the vacuum heat insulating material. By orienting the fiber material in this way, the amount of heat conducted along the crossing direction, that is, along the thickness direction of the vacuum heat insulating material, is remarkably reduced with respect to the amount of heat conducted along the fiber material orientation direction. Thereby, it becomes possible to improve the heat insulation performance of a vacuum heat insulating material.

It is possible to carry out by the manufacturing process including.

  When manufacturing a vacuum heat insulating material by the said manufacturing process, an inorganic fiber is preferable as a fiber material, and especially glass wool or glass fiber is suitable. In addition, it is preferable to use an inorganic material for the binder. By using an inorganic material for the binder, the generation of gas from the binder accompanying a change with time is suppressed, and deterioration of the heat insulating performance of the vacuum heat insulating material with time is suppressed.

A board-like core material can be made without using a binder. For example, glass fibers are laminated and arranged in the thickness direction to form a glass fiber aggregate in which the fibers are partially entangled, and then the glass fiber aggregate is slightly deformed by its own weight. The density of the core material at a temperature (for example, 460 to 480 ° C.) at which the glass fiber can be deformed by the temperature or the load from the up and down direction during pressing and the cross-sectional shape of the glass fiber does not change greatly. Is heated and pressed so as to be 200 to 300 kg / m ³ , thermally deformed into the shape at the time of hot pressing, and then the glass fiber aggregate thermally deformed in the state at the time of hot pressing is cooled, thereby A board-like core material in which the shape of the time is maintained and the restraint and the integrity in the thickness direction are enhanced can be produced.

  Moreover, in this invention, as a structure which connects vacuum heat insulating materials, for example, the structure which piles up the seal parts of the vacuum heat insulating material located in a connection part, and joins them with an adhesive agent, and overlaps seal parts. The structure to weld can be taken.

According to an eighteenth aspect of the present invention, in the method for delivering frozen goods according to any one of the first to sixteenth aspects, the cold insulation container is capable of opening and closing the cold insulation container with a peripheral wall portion and a bottom surface portion of four surfaces. The integrated vacuum heat insulating material in a developed view having a lid portion is folded into a box shape, and the vacuum heat insulating material covers the board-shaped core material with a jacket material having gas barrier properties and flexibility, The inside of the jacket material is formed by depressurizing and vacuum-sealing, and the vacuum heat insulating material is a portion where the core material does not exist between the jacket materials, and a seal portion where the jacket materials are welded together The configuration is such that it is disposed along a connecting part between the parts and a bent part provided in at least one of the parts.

  According to this invention, a surrounding wall part, a bottom face part, and a cover part are comprised with an integral vacuum heat insulating material. Therefore, high cold insulation performance is realized, material cost is low, wall thickness is thin, volumetric efficiency is high, and the cold insulation container can be made compact when folded. Assembling and folding can be easily performed in a short time without the need for removing the member.

According to a nineteenth aspect of the present invention, in the frozen merchandise delivery method according to the seventeenth or eighteenth aspect of the invention, the vacuum heat insulating material has a reinforcing structure in which a covering material positioned on the outer surface side of the box formed by the respective parts It is set as the structure.

  According to the present invention, even when an external force is applied to the outer surface side of the cold storage container (box body), the outer jacket material is prevented from being broken and durability is improved.

  As the reinforcement structure of the jacket material, a configuration in which the thickness of the jacket material is increased within a range that does not impair flexibility can be adopted. That is, when using a laminate film in which a heat-welding layer is laminated on the inner surface side of the gas barrier layer using the above-described metal foil or metal vapor deposition film, and a protective layer is laminated on the outer surface side of the gas barrier layer, as the jacket material, A reinforcing structure can be obtained by increasing the thickness of the gas barrier layer or the protective layer.

  Embodiments of the present invention will be described below with reference to the drawings.

FIG. 6 is a view in the direction of arrow C in FIG. 5, FIG. 7 is a cross-sectional view in the direction of arrow EE in FIG. 5, and FIG. 8 is a cross-sectional view in the direction of arrow BB in FIG. Sectional drawing which shows the state which released the engagement of the bottom face part, Fig.9 (a)-(e) is a perspective view which shows the procedure which folds the cold insulator 1 of FIG. 10 (a) is a perspective view showing a state in which the cold insulation container 1 of FIG. 3 is housed in a protective container, and FIGS. 10 (b) and (c) show the cold insulation container 1 folded when not in use as a protective container. It is a perspective view which shows the state to accommodate.

  As shown in FIG. 1, the cold insulation container 1 used in the delivery method of the first embodiment is formed by four peripheral wall portions 10, 10, 13, 13, a bottom surface portion 21, and two cover portions 16, 16. It is a box-shaped container.

  Each part of these peripheral wall parts 10 and 13, the bottom face part 21, and the cover part 16 is formed by including the vacuum heat insulating material 31 inside the sheet material, and has a very high heat insulating property.

  The cold insulation container 1 used in the present embodiment has a width of 600 mm, a depth of 400 mm, a height of 300 mm, and an internal volume of approximately 70 liters.

  The cold insulation container 1 has a structure in which the peripheral wall portions 10 and 13, the bottom surface portion 21, and the lid portion 16 are connected to each other so as to be bendable, and these portions can be folded and folded as will be described later. Yes.

  In the delivery method of the present embodiment, by performing a test in advance, each of the cases where the cold storage container 1 is loaded on each delivery vehicle M (refrigerated vehicle M1, cold storage vehicle M2, normal temperature vehicle M3) is stored in the cold storage container 1. An approximate quality retention time of the frozen product S relative to the storage rate of the frozen product S is required. In other words, an approximate quality retention time table as shown in (Table 1) is created by conducting tests in advance.

（表１）から分かるように、冷蔵車は庫内温度が冷蔵温度に設定されるので、保冷車や常温車に比較して冷凍商品Ｓの品質保持時間が長い。また、保冷車は収納庫が断熱性を有するので、常温車よりも品質保持時間が長くなる。

As can be seen from (Table 1), since the temperature inside the refrigerator is set to the refrigerator temperature, the quality retention time of the frozen product S is longer than that of the cold storage vehicle or the normal temperature vehicle. In addition, since the storage of the cold storage vehicle has heat insulation, the quality retention time is longer than that of the normal temperature vehicle.

  In the present embodiment, data in (Table 1) is created assuming that the quality of the frozen product S is maintained and the internal average temperature of the cold container 1 is 0 ° C. or less.

  When delivering the frozen product S, as shown in FIG. 1 (a), first, the delivered frozen product S (S1 to S4) is stored in the cold container 1, and an approximate storage ratio of the frozen product S is obtained by visual inspection. Next, the time required until the delivery destination is examined, and a vehicle type that can secure a quality retention time exceeding the required delivery time is selected with reference to the column corresponding to the storage ratio of the frozen goods in (Table 1).

  In other words, for example, when the storage ratio of the frozen product S in the cold container 1 is approximately 80% and the time required for the delivery destination is approximately 1 hour 30 minutes, the delivery that maintains the quality only by the refrigerator car is performed. Is possible.

  Further, when the storage rate of the frozen product S is approximately 100% and the time required for delivery is approximately 30 minutes, delivery can be performed by any of a refrigerator car, a cold car, and a room temperature car.

  Next, as shown in FIG. 1B, the lids 16 and 16 of the cold insulation container 1 containing the frozen product S are closed, and the cold insulation container 1 is loaded on the delivery vehicle M as shown in FIG. At this time, if the delivery vehicle M is the refrigerated vehicle M1, the refrigerated product Q1 can be simultaneously loaded in addition to the cold storage container 1 in which the frozen product S is stored. Moreover, if the delivery vehicle M is the cold storage vehicle M2, in addition to the cold storage container 1 that stores the frozen product S, the cold storage product Q2 can be loaded simultaneously. Similarly, if the delivery vehicle M is a normal temperature vehicle M3, the normal temperature product Q3 can be simultaneously loaded in addition to the cold storage container 1 in which the frozen product S is stored.

  In this way, the frozen products S and the products Q that can be loaded on the delivery vehicle M are collectively loaded and delivered to the delivery destination. After delivering the frozen product S and the product Q to the delivery destination, as shown in FIG. 1 (d), the refrigerated cold insulation container 1 is collected and folded and loaded in the delivery vehicle M in a folded state.

  On the other hand, there may be a case where the cold storage container 1 containing the frozen product S is delivered to the delivery destination as it is, and the empty cold storage container 1 is collected at a later delivery. In this case, when all the frozen products S stored in the cold storage container 1 are taken out, the cold storage container 1 whose delivery destination itself is empty can be folded and stored. Thereby, the empty cool container 1 does not occupy useless space at the delivery destination, and can be easily collected at the later delivery.

  In addition, when delivering the frozen goods S stored in the cold storage container 1 to a plurality of different delivery destinations, it is complicated to determine the deliverable vehicle with reference to (Table 1). In such a case, delivery can be performed with reference to (Table 1) based on the average storage ratio of the frozen products S stored in each cold storage container 1 and the average required time to different delivery destinations. A vehicle may be determined.

  Thus, according to the delivery method of the frozen goods of this Embodiment, since the cold storage performance of the cold storage container 1 is high, the frozen goods S are accommodated in the cold storage container 1 without using a cool storage agent, and other than the refrigerator car. Delivery can be performed using a delivery vehicle, and the delivery cost can be reduced compared to the case of using a refrigerator vehicle. In addition, the products originally delivered by the delivery vehicle can be delivered together, and the delivery cost can be greatly reduced.

  In addition, by delivering frozen products at the same time as other refrigerated products, the number of delivery vehicles to be used can be reduced, and it is possible to perform excellent delivery in terms of environmental protection.

  Next, a delivery method according to the second embodiment of the present invention will be described with reference to FIG.

  The cold insulation container 1 used for the delivery method of the second embodiment has the same configuration as the cold insulation container 1 used in the first embodiment. Accordingly, the same reference numerals are assigned and redundant description is omitted.

  The delivery method shown in the first embodiment is suitable for short-time delivery, in which only the frozen goods to be delivered are stored and delivered in the cold container 1.

  On the other hand, the delivery method of the present embodiment is suitable for long-time delivery in which the cold storage container 1 is housed and delivered in the cold storage container 1 in addition to the frozen product S to be delivered.

  In the delivery method of the present embodiment, the cold storage container 34 is stored for each case where the cold storage container 1 is loaded on each delivery vehicle M (refrigeration vehicle M1, cold storage vehicle M2, normal temperature vehicle M3) by performing a test in advance. There is a need for a time for delivery while maintaining the quality of the frozen product S with respect to the quantity. In other words, an approximate delivery time table as shown in (Table 2) is created by conducting a test in advance.

（表２）から分かるように、冷蔵車は庫内温度が冷蔵温度に設定されるので、保冷車や常温車に比較して配送可能時間が長い。また、保冷車は収納庫が断熱性を有するので、常温車よりも配送可能時間が長い。

As can be seen from (Table 2), since the refrigerator temperature is set to the refrigerator temperature, the refrigerated vehicle has a longer delivery time compared to the cold storage vehicle and the normal temperature vehicle. Further, since the storage car has a heat insulating property, the cooler car has a longer delivery time than the normal temperature car.

  In the present embodiment, data in (Table 2) is created assuming that the quality of the frozen product S is maintained and the internal average temperature of the cold container 1 is 0 ° C. or less.

  When the frozen product S is delivered, the frozen product S (S1 to S4) to be delivered to the cold container 1 is stored as shown in FIG. Further, referring to (Table 2), the storage amount of the regenerator is obtained from the vehicle type used for delivery and the time required for the delivery destination.

  That is, for example, when delivering to a delivery destination having a delivery time of 10 hours using the refrigerator car M1, it is necessary to store 1 kg of the regenerator per 50 liters of the internal volume of the cold container 1. Therefore, it can be seen that when the internal volume of the cold insulation container 1 is 70 liters as in the present embodiment, approximately 1.4 kg of the cold storage agent should be stored.

  Next, as shown in FIG. 2A, the frozen product S (S1 to S4) and the previously determined 1.4 kg of the cold storage agent 34 are stored in the cold storage container 1. Then, as shown in FIG. 2B, the lids 16 and 16 of the cold insulation container 1 containing the frozen product S and the cold storage agent 34 are closed, and the cold insulation container 1 is delivered to the delivery vehicle M as shown in FIG. To load.

  At this time, if the delivery vehicle M is the refrigerated vehicle M1, the refrigerated product Q1 can be simultaneously loaded in addition to the cold storage container 1 in which the frozen product S is stored. Moreover, if the delivery vehicle M is the cold storage vehicle M2, in addition to the cold storage container 1 that stores the frozen product S, the cold storage product Q2 can be loaded simultaneously. Similarly, if the delivery vehicle M is a normal temperature vehicle M3, the normal temperature product Q3 can be simultaneously loaded in addition to the cold storage container 1 in which the frozen product S is stored.

  In this way, the frozen product S and the product Q that can be loaded on the delivery vehicle M are simultaneously loaded and delivered to the delivery destination. And after delivering frozen goods S and goods Q to a delivery place, as shown in Drawing 2 (d), empty cold storage container 1 is collected and folded. Thereby, the collect | recovered cold storage container 1 can be easily returned to the delivery vehicle M. FIG.

  Similarly to the first embodiment, when the cold insulated container 1 storing the frozen product S is delivered to the delivery destination as it is, when the frozen product S stored in the cold insulated container 1 is all taken out, the delivery destination The cold storage container 1 that has been emptied can be folded and stored. Thereby, the empty cool container 1 does not occupy useless space at the delivery destination, and can be easily collected at the later delivery.

  Thus, according to the delivery method of the frozen goods of this Embodiment, since the cold insulation performance of the cold insulating container 1 is high, by using the cool storage agent 34, the frozen goods S can be extended using a delivery vehicle other than the freezing vehicle. Time delivery can be performed, and the delivery cost can be reduced as compared with the case of using a refrigerator car. In addition, the products originally delivered by the delivery vehicle can be delivered together, and the delivery cost can be greatly reduced.

  In addition, by delivering frozen products at the same time as other refrigerated products, the number of delivery vehicles to be used can be reduced, and it is possible to perform excellent delivery in terms of environmental protection.

  In the first and second embodiments, the cold insulation container 1 has been described as being foldable. However, the delivery method of the present invention can also be implemented using a cold insulation container that is fixed to a box. It is.

  In the above-described embodiment, the case where the refrigerator car M1, the cold car M2, and the normal temperature car M3 are used as the delivery car M has been described as an example. For example, even if there is no cold car M2, the cold car M1 and the normal temperature car By creating the data of the above (Table 1) and (Table 2) for the vehicle M3, it is possible to carry out the delivery of frozen goods in the same manner.

  Next, a specific embodiment of the cold container 1 employed in the frozen merchandise delivery method described in the first and second embodiments will be described.

  The cold insulation container 1 used in the above-described embodiment is a foldable cold insulation container that is a box when used and can be folded when not in use.

  As shown in FIG. 3, the cold insulation container 1 includes four peripheral wall portions 10, 10, 13, and 13 that are connected to each other in a rectangular shape so as to be bent, and an upper edge 11 of the two opposing peripheral wall portions 10 and 10. , 11 along the two sides of the lids 16, 16 connected so as to be bendable, and along the lower edges 12, 12 of the two peripheral walls 10, 10 connected to the lids 16, 16. It is formed to include two bottom surface portions 21 and 21 that are connected so as to be bendable.

  In the present embodiment, the cover portion 16 has a length toward the facing cover portion 16, that is, a length L from the upper edge 11 of the peripheral wall portion 10 to the side edge 17 of the cover portion 16, and the peripheral wall portion 13. The lid portions 16, 16 on the two surfaces have the same shape. Further, the bottom surface portions 21 and 21 of the two surfaces have the same shape as the lid portion 16. Further, the length L of the lid portion 16 is shorter than the height H of the peripheral wall portion 10.

  Specifically, as shown in FIG. 3, the cold container 1 of the present embodiment has a width W of 600 mm, a depth D of 400 mm, and a height H of 300 mm, and the length L of the lid portion 16 is substantially the same. The configuration is 200 mm and shorter than the height H. The internal volume of the cold container 1 is approximately 70 liters.

  As shown in FIG. 4, the peripheral wall portion 10, the lid portion 16, and the bottom surface portion 21 are all formed by including a flat vacuum heat insulating material 31 in a sheet material 30.

  As shown in FIG. 4, the vacuum heat insulating material 31 covers a core material 32 made of at least one of a fiber material, a resin foam material, and a granular material with an outer covering material 33 having a gas barrier property. It is a heat insulating material formed by decompressing the inside and vacuum-sealing it.

  In the present embodiment, a laminate film formed by laminating a heat welding layer and a protective layer on the inside and outside of the gas barrier layer is used as the covering material 33. In other words, the covering material 33 is made of a metal foil such as aluminum or a film deposited with metal or non-oxide as a gas barrier layer, and a film such as unstretched polypropylene is used as a heat welding layer on the inner surface side of the gas barrier layer. In addition to being laminated, a laminate film in which a film such as nylon or polyethylene terephthalate is laminated as a protective layer on the outer surface side of the gas barrier layer.

  Moreover, the core material 32 used what heat-molded the fiber material using the binder.

  When a fiber material is employed as the core material 32, it is preferable that the fiber elements of the fiber material are aligned and oriented so as to intersect the thickness direction of the vacuum heat insulating material 31. By orienting the fiber material in this way, the amount of heat conducted along the crossing direction, that is, along the thickness direction of the vacuum heat insulating material 31, is significantly reduced with respect to the amount of heat conducted along the fiber material orientation direction. . Thereby, the heat insulation performance of the vacuum heat insulating material 31 can be improved.

  In order to orient the fiber material forming the core material 32 so as to intersect with the thickness direction of the vacuum heat insulating material 31, for example, a step of laminating the fiber material into a predetermined shape, A step of applying a binder aqueous solution or water to at least one surface of the outer surface, a step of compressing the laminated fiber web coated with the binder at a temperature of 100 ° C. or lower, and a step of heating and compressing the compressed laminated fiber web at a temperature of 100 ° C. or higher. It is possible to carry out by the manufacturing process containing these.

  When manufacturing the vacuum heat insulating material 31 by the said manufacturing process, an inorganic fiber is preferable as a fiber material, and especially glass wool or glass fiber is suitable. In addition, it is preferable to use an inorganic material for the binder. By using an inorganic material for the binder, the generation of gas from the binder accompanying a change with time is suppressed, and deterioration of the heat insulation performance of the vacuum heat insulating material 31 with time is suppressed.

The board-like core material 32 can be made without using a binder. For example, glass fibers are laminated and arranged in the thickness direction to form a glass fiber aggregate in which the fibers are partially entangled, and then the glass fiber aggregate is slightly deformed by its own weight. The density of the core material at a temperature (for example, 460 to 480 ° C.) at which the glass fiber can be deformed by the temperature or the load from the up and down direction during pressing and the cross-sectional shape of the glass fiber does not change greatly. Is heated and pressed so as to be 200 to 300 kg / m ³ , thermally deformed into the shape at the time of hot pressing, and then the glass fiber aggregate thermally deformed in the state at the time of hot pressing is cooled, thereby The board-shaped core material 32 in which the shape of the time is maintained and the restraint and the integrity in the thickness direction are enhanced can be produced.

  In the present embodiment, the vacuum heat insulating material 31 having such a configuration having a thermal conductivity (initial thermal conductivity) of 0.005 W / mK and a thickness of 10 mm is used. Thereby, while ensuring the high heat insulation in the surrounding wall part 10, the cover part 16, and the bottom face part 21, thickness reduction of the said each part is aimed at.

  The sheet material 30 is formed by sewing a polyester fabric with a synthetic resin coat on the back surface, and has water resistance, waterproofness and flexibility.

  In the present embodiment, a sheet having a thickness of 4 mm is provided on the outer wall surface of the peripheral wall portion 10, the lid portion 16, and the bottom surface portion 21 when the cold insulation container 1 is used or not used, as shown in FIG. A material 30a is used, and a sheet material 30b having a thickness of 2 mm is used on the other surface.

  In other words, each of the peripheral wall portion 10, the lid portion 16, and the bottom surface portion 21 of the cold insulation container 1 has the vacuum heat insulating material 31 inside the sheet material 30 sewn in a bag shape having water resistance, waterproofness, and flexibility. It is an enclosed structure. The peripheral wall portion 10, the lid portion 16, and the bottom surface portion 21 can be bent by connecting the side edges of the sheet material 30 to each other by sewing.

  Further, as shown in FIG. 3, the two peripheral wall portions 13, 13 adjacent to the peripheral wall portions 10, 10 connected to the lid portion 16 and the bottom surface portion 21 are formed by folding lines 23 extending in the height direction substantially at the center portion. The vacuum heat insulating material is divided along the folding line 23, and the peripheral wall portion 13 can be bent along the folding line 23.

  In other words, the peripheral wall portion 13 is formed by storing two vacuum heat insulating materials 31 and 31 inside a sheet material 30 sewn in a bag shape, and sewing the sheet material 30 along a fold line 23. It is possible to bend along the line 23.

  As shown in FIGS. 3 and 5, one lid portion 16 is provided with a flexible engagement flap 18 having a surface fastener 18 a along the side edge 17, and the other lid portion 16 has A hook-and-loop fastener 20 is provided so as to correspond to the engagement flap 18 of one lid portion 16. The engagement flap 18 also uses the above-described sheet material 30b (thickness 2 mm, see FIG. 4), and is formed by sewing a surface fastener 18a on the sheet material 30b.

  As shown in FIGS. 3 and 5, a flexible engagement flap 24 having a surface fastener 24 a is provided substantially upward along the upper edge 14 on the two peripheral wall portions 13 that can be bent. It is attached by sewing in a state of being biased toward. The engagement flap 24 also uses the above-described sheet material 30b (thickness 2 mm, see FIG. 4), and is formed by sewing a surface fastener 24a on the sheet material 30b.

The inner lid 25 is a shielding material for assisting the shielding by the lid portion 16.

  In the present embodiment, the inner lid 25 has a width substantially equal to the width W of the cold container 1 as shown in FIG. 3, and the length thereof is the lower end of the inner surface of the opposed peripheral wall portion 10 as shown in FIG. It is said that it is more than the length. By setting the inner lid 25 to this size, as shown in FIG. 7, even when the frozen products S1 to S4 are stored in a part of the inside of the cold container 1 and a gap is generated, all of the frozen products S1 to S4 are removed. It can be covered with the inner lid 25, and the shielding effect is increased.

  In addition, a cool storage agent storage unit 26 that stores a cool storage agent is provided inside the cold insulation container 1. The cool storage agent storage portion 26 is a bag formed using a mesh net material as shown in FIGS. 3 and 7, and the cool storage agent 34 can be stored therein as shown in FIG. 7. In the present embodiment, the regenerator storage portion 26 is provided on the inner surface of the peripheral wall portion 10 to which the inner lid 25 is connected. Thereby, the cool storage agent 34 and frozen goods S1-S4 can be easily covered with the inner cover 25, and the cold preservation performance and shielding property of frozen goods S1-S4 are aimed at.

  In addition, the cool storage agent storage part 26 can be provided not only on the inner surface of the peripheral wall part 10 but also on the inner surfaces of the peripheral wall part 13 and the lid part 16.

  In the present embodiment, the cool storage agent storage unit 26 can store two cool storage agents 34 having a melting point of −27 ° C. to −18 ° C. and a weight of 1 kg. Moreover, the cool storage agent 34 used in this embodiment is “CAH-1001 minus 25 ° C. grade” manufactured by Inoac Corporation.

  Next, an assembling procedure at the time of using the cold insulating container 1 of the present embodiment will be described.

  First, as shown in FIG. 8, the bottom surface portions 21 and 21 are rotated to the closed posture (horizontal direction), and the side edges 29 and 29 are brought into contact with each other as shown in FIG. Then, the engagement flap 22 provided on one bottom surface portion 21 is pressed against the other bottom surface portion 21 so that the surface fastener 22a of the engagement flap 22 and the surface fastener 28 of the other bottom surface portion 21 are engaged with each other.

  When the bottom surface portions 21 and 21 are engaged in this way, a substantially flat surface is formed by both the bottom surface portions 21 as shown in FIG. 7, and the bottom sheet 27 is positioned below the bottom surfaces 21 and 21 so as to cover the entire surface. To do. Accordingly, even when a slight gap is generated between the bottom surface portion 21 and the peripheral wall portion 13, the communication between the inside and the outside is blocked by the bottom surface sheet 27, and the cold insulation performance is not impaired.

  In the present embodiment, the bottom sheet 27 is made of a water-resistant and waterproof sheet material 30b to prevent water staying inside from flowing out of the container.

  Next, as shown in FIG. 7, the above-described regenerator 34 is stored in the regenerator storage unit 26 as necessary, and frozen products S1 to S4 such as frozen food to be delivered are stored inside, and the frozen product S1 is stored. Put the inner lid 25 to cover ~ S4.

  Here, in the present embodiment, the regenerator 34 having a melting point of −27 ° C. or higher and −18 ° C. or lower is used. Usually, in a wholesaler or a distribution center that performs small-lot delivery, the temperature of a refrigerated warehouse is often controlled to about −30 ° C. to −22 ° C. Accordingly, the regenerator 34 having the melting point in the above range is used so that the regenerator 34 can be solidified only by storing in the freezer warehouse. Thereby, at the time of delivery, it becomes possible to immediately store the refrigerating agent stored in the refrigeration warehouse and solidified in the cold insulation container 1 for cold preservation.

  When all the frozen products S1 to S4 to be stored are stored, the lid portions 16 and 16 are rotated to the closed posture (substantially horizontal direction). As shown in FIG. 5, when the lid portions 16 and 16 are turned inward, the engagement flap 24 provided substantially upward on the peripheral wall portion 13 is pressed by the turning of the lid portion 16 to be inside. The hook-and-loop fastener 24a of the engagement flap 24 and the hook-and-loop fastener 19 of the lid 16 are engaged with each other. When both the lid portions 16 and 16 are moved to the closed posture, the entire surface fastener 24a of the engagement flap 24 is engaged with the surface fastener 19 of the lid portion 16, and the gap between the lid portion 16 and the peripheral wall portion 13 is established. It is shielded by the engagement flap 24.

  Moreover, when the cover parts 16 and 16 are moved to a closed position, the side edges 17 and 17 of the cover parts 16 and 16 will face each other like FIG. Finally, the engagement flap 18 provided on one lid 16 is pressed against the other lid 16 to engage the surface fasteners 18a and 20 with each other. Thereby, the abutting part of the side edges 17 and 17 of the lid parts 16 and 16 is covered with the engagement flap 18.

  In other words, the cold insulation container 1 of the present embodiment is configured by simply rotating the bottom surface portions 21 and 21 and the lid portions 16 and 16 to the closed posture and engaging them with the engagement flaps 22 and 18 as shown in FIG. As described above, a box surrounded by the peripheral wall portions 10 and 13, the bottom surface portion 21, and the lid portion 16 including the vacuum heat insulating material 31 is formed.

  The formed box body is covered with the engagement flap 22 at the abutting portion between the side edges 29 and 29 of the bottom surface portions 21 and 21, and the outer surface of the bottom surface portion 21 is a bottom sheet 27 as shown in FIG. Covered. Further, as shown in FIG. 6, the abutting portions of the lid portions 16 and 16 are covered with the engagement flap 18, and the gap between the lid portion 16 and the peripheral wall portion 13 is shielded by the engagement flap 24.

  As described above, the cold insulation container 1 according to the present embodiment is assembled by moving the bottom surface portions 21 and 21 and the lid portions 16 and 16 to the closed posture, and the communication between the inside and the outside is completely blocked, and the entire surface is vacuum insulated. It is possible to form a box body surrounded by materials and having extremely high heat insulating properties.

  In the present embodiment, by storing one cold storage agent having a melting point of −27 ° C. or more and −18 ° C. or less per 50 liters inside the cold insulation container 1, the average temperature of the atmosphere inside the cold insulation container 1 is set. It can be maintained at 0 ° C. or lower continuously for 10 hours or longer, and can be maintained at about −15 ° C. continuously for 10 hours or longer if replaced with the product temperature of a frozen product (for example, ice cream). Therefore, by delivering the cold storage container 1 in combination with the cold storage agent according to the present embodiment, it is possible to maintain the frozen product at a low temperature and perform long-distance delivery without damaging the quality.

  Next, the folding procedure of the cold insulation container 1 when not in use will be described.

  The cold storage container 1 is folded, for example, when the cold storage container 1 is emptied after delivery or when the cold storage container 1 is stored and returned to the delivery source. In the following description of the folding procedure, it is assumed that the cool storage agent 34 stored in the cool storage agent storage unit 26 has been taken out.

  At the time of folding, first, as shown in FIG. 9A, the engaging flap 24 of the lid portion 16 of the cold insulation container 1 which is a box is grasped and pulled up. 9B, the engagement between the surface fastener 18a of the engagement flap 18 and the surface fastener 20 of the lid portion 16, and the engagement of the surface fastener 24a of the engagement flap 24 and the surface fastener 19 of the lid portion 16. The lids 16 and 16 are rotated to the open posture while releasing the engagement.

  Next, as shown in FIG. 8 and FIG. 9C, the inner lid 25 is moved toward the regenerator storage unit 26, the engagement flap 22 of the bottom surface portion 21 is grasped and pulled up, and the surface fastener 22 a of the engagement flap 22 is The engagement of the hook-and-loop fastener 28 of the bottom surface portion 21 is released. 9D, the bottom surface portions 21 and 21 are folded on the inner surfaces of the peripheral wall portions 10 and 10, and the lid portions 16 and 16 are folded on the outer surfaces of the peripheral wall portions 10 and 10, respectively.

  Subsequently, as shown in FIG. 9D, the peripheral wall portions 10 are brought close to each other while the peripheral wall portions 13 are bent inward along the fold line 23. As a result, as shown in FIG. 9 (e), the four surfaces of the lid portion 16, the peripheral wall portion 10, the bottom surface portion 21, and the bent peripheral wall portion 13 are overlapped in order from the outside, and all eight surfaces overlap. Folding is completed in the state.

  As described above, the cold insulation container 1 of the present embodiment can be folded very easily and compactly in a short time without attaching / detaching a member such as a heat insulating panel as in the prior art.

  When the cold insulation container 1 is folded, as shown in FIG. 9E, a total of eight surfaces of the lid portions 16 and 16, the peripheral wall portions 10 and 10, the bottom surface portions 21 and 21 and the peripheral wall portions 13 and 13 are folded. Become.

  Further, as described above, in the present embodiment, the length L (200 mm) of the lid portion 16 and the bottom surface portion 21 is shorter than the height H (300 mm) of the peripheral wall portions 10 and 13. Thereby, when the cold insulation container 1 is folded, it becomes a shape in which the eight surfaces are overlapped with the peripheral wall portion 10 as the maximum outer dimension.

  Further, the cold insulation container 1 of FIG. 3 uses the thick sheet material 30a shown in FIG. 4 for all surfaces located on the outside side when in use or not in use. That is, the thick sheet material 30a shown in FIG. 4 is employed on the outer surface side of the peripheral wall portion 10, the peripheral wall portion 13 and the bottom surface portion 21, and on the inner surface and outer surface side of the lid portion 16, respectively.

  More specifically, the lid portion 16 has a thickness of 18 mm, which is the sum of the thickness (10 mm) of the vacuum heat insulating material 31 and the thickness (4 mm + 4 mm) of the sheet material 30a that encloses it. The peripheral wall portions 10 and 13 have a thickness of 16 mm, which is the sum of the thickness (10 mm) of the vacuum heat insulating material 31 and the thicknesses (4 mm + 2 mm) of the sheet materials 30a and 30b enclosing it. Further, the bottom surface portion 21 has a thickness of 16 mm, which is the sum of the thickness (10 mm) of the vacuum heat insulating material 31 and the thicknesses (4 mm + 2 mm) of the sheet materials 30a and 30b enclosing it. Therefore, when the eight surfaces are folded and overlapped, the total thickness becomes approximately 132 mm.

  In other words, when the cold insulation container 1 of the present embodiment is folded, the outer dimension (W600 mm × H300 mm) of the peripheral wall portion 10 can be the maximum outer dimension, and the thickness can be reduced to approximately 132 mm. Compared to this, it can be made extremely compact. Thereby, collection | recovery and storage after use can be performed easily.

  In addition, as described in the embodiment of the delivery method, even when the cold storage container 1 storing the frozen product S is delivered to the delivery destination as it is, the delivery destination folds compactly after the use of the cold storage container 1. The empty cold container 1 does not occupy useless space. In particular, the cold storage container 1 according to the present embodiment can be assembled and folded very easily in a short time, and the use of the cold storage container 1 that has been discontinued due to troublesome folding is left as a box and is useless. Occupying space is eliminated.

  Moreover, since the cold insulation container 1 is comprised by one member connected so that bending is possible, a member is not attached or detached in the case of folding, and there is no possibility that a part of member may be lost.

  Moreover, since the cold storage container 1 can be folded compactly, it is also possible to store a plurality of folded cold storage containers 1 in a general-purpose roll pallet or the like and easily move them.

  Further, as described above, the thick sheet material 30a is used for all the surfaces positioned on the outside side when in use or not in use.

  Accordingly, when the box is formed in use, the vacuum heat insulating material 31 included in each surface is protected from external force by the thick sheet material 30a. When folded when not in use, the inner surface of the lid portion 16 is protected from external force by the thick sheet material 30a. Thereby, it is possible to protect the vacuum heat insulating material 31 from external force both at the time of use and at the time of non-use, prevent the vacuum heat insulating material 31 from being damaged, and improve the durability.

  Here, as described above, the cold insulation container 1 of the present embodiment is formed by the lid portion 16, the peripheral wall portions 10 and 13 and the bottom surface portion 21 including the vacuum heat insulating material 31 having predetermined strength and rigidity. Therefore, even when the cold container 1 is used alone, a certain degree of strength and rigidity can be obtained. However, the durability of the cold insulation container 1 can be remarkably improved by storing the cold insulation container 1 in a protective container having higher strength and rigidity and using it as a set.

  For example, as shown in FIG. 10 (a), a protective container 2 that can completely store the cold-reserving container 1 is prepared, and the structure can be used in which the cold-reserving container 1 that is a box is stored and used as a set for delivery. .

  The protective container 2 shown in FIG. 10 (a) is manufactured by molding a synthetic resin material, has a box shape with the top opened, and is extremely lightweight. The protective container 2 is formed with flange portions 2a and 2b by projecting the outer surfaces of the upper and lower portions over the entire circumference. Therefore, the protective container 2 can be easily carried using the flange portion 2a as a clue. In addition, the lids 16 and 16 can be opened and closed by grasping the engagement flap 18 while the cold container 1 is stored in the protective container 2.

  In addition, the flange portion 2b of the protective container 2 is overlapped with the flange portion 2a of another protective container 2 and can be engaged, and the protective containers 2 can be stacked in multiple stages. Therefore, even when a large number of protective containers 2 containing the cold storage containers 1 are loaded on a delivery vehicle, the loading space can be effectively used by stacking them in multiple stages, and an excessive load is not directly applied to the cold storage containers 1. There is no damage.

  As described above, the durability of the cold insulation container 1 can be remarkably improved by using the cold insulation container 1 together with the reduced weight protective container 2 as a set.

  Furthermore, as shown in FIG.9 (e), the cold insulation container 1 can be folded in the shape where eight surfaces were piled up by making the surrounding wall part 10 into the largest outer dimension. Therefore, as shown in FIGS. 10B and 10C, a plurality of folded cold storage containers 1... Can be stored in one protective container 2.

  As a result, a plurality of cold storage containers 1 can be collectively stored in the protective container 2 and easily carried, and preparation work and collection work for delivery can be performed efficiently. In addition, a plurality of cold storage containers 1 can be arranged and stored in the protective container 2, and the storage space can be reduced.

  Although the protective container 2 shown in FIG. 10 has been described as being formed in a box shape, the protective container 2 can be folded to facilitate carrying of the protective container 2 during preparation and collection. The storage space can also be reduced.

  In the present embodiment, the peripheral wall portions 10 and 13, the lid portion 16, and the bottom surface portion 21 of the cold insulation container 1 are made of a sheet material 30 that is sewn in a bag shape having water resistance, waterproofness, and flexibility. The vacuum heat insulating material 31 is included inside, and the peripheral wall portion 10, the lid portion 16, and the bottom surface portion 21 can be bent by connecting the side edges of the sheet material 30 by sewing. However, the sheet material 30 may be omitted, and the four peripheral wall portions 10, the bottom surface portion 21, and the openable / closable lid portion 16 may be formed of vacuum heat insulating materials connected to each other.

  When the sheet material 30 is omitted, the cold insulation container has four peripheral wall portions, a bottom surface portion, and an openable / closable lid portion, and each of the portions is composed of a vacuum heat insulating material connected to each other, and the vacuum The heat insulating material is formed by covering a board-shaped core material with a jacket material having gas barrier properties and flexibility, and depressurizing and vacuum-sealing the inside of the jacket material, and the vacuum heat insulating material is formed of the jacket material. A seal portion in which a core material does not exist between the outer cover materials is disposed along a connecting portion between the portions and a bent portion provided in at least one of the portions. It becomes composition.

  In the case of the above configuration, since the peripheral wall portion, the bottom surface portion, and the lid portion can be composed only of the vacuum heat insulating materials connected to each other, high cold insulation performance is expressed, and the sheet material 30 is unnecessary, so the material cost is low. Further, the productivity can be further improved and the cost can be reduced, and the wall thickness is thin, the volumetric efficiency is high, and the cold storage container can be made compact when folded.

  In addition, as a configuration for connecting the vacuum heat insulating materials, for example, a configuration in which the seal portions of the vacuum heat insulating materials located in the connection portion are overlapped and joined with an adhesive, a configuration in which the seal portions are overlapped and welded, Further, it is possible to adopt a configuration in which the seal portions are overlapped and sewn together.

  Moreover, as for the vacuum heat insulating material in the case of omitting the sheet material 30, it is desirable that the covering material positioned on the outer surface side of the box formed by each part has a reinforcing structure.

  As the reinforcement structure of the jacket material, a configuration in which the thickness of the jacket material is increased within a range that does not impair flexibility can be adopted. That is, when using a laminate film in which a heat-welding layer is laminated on the inner surface side of the gas barrier layer using the above-described metal foil or metal vapor deposition film, and a protective layer is laminated on the outer surface side of the gas barrier layer, as the jacket material, A reinforcing structure can be obtained by increasing the thickness of the gas barrier layer or the protective layer.

  By the way, although the structure using the some vacuum heat insulating material 31 was employ | adopted for the cold insulation container 1 of this Embodiment, it is also possible to form these vacuum heat insulating materials integrally.

  The vacuum heat insulating material 41 shown in FIG. 14 has peripheral wall portions 10 and 13 and a lid portion in accordance with the developed shape of the cold insulation container 1 (the shape of the developed view in which one connection portion between the peripheral wall portion 10 and the peripheral wall portion 13 is cut). 16 and the bottom surface portion 21 are all integrally formed with the vacuum heat insulating material 31.

  Next, the manufacturing method of the vacuum heat insulating material 41 is demonstrated. First, as shown in FIG. 11, each of the peripheral wall portions 10, 13, the lid portion 16, and the bottom surface portion 21 is disposed on a single rectangular jacket member 43 including the developed shape of the cold container 1. The core materials 42a, 42b, 42c, and 42d matched to the shape of the core material 32 of the vacuum heat insulating material 31 are developed shapes of the cold insulation container 1 (one development portion cut off at one connection portion between the peripheral wall portion 10 and the peripheral wall portion 13). To match the shape).

  At this time, the interval between the core material 42a of the peripheral wall portion 10 and the core material 42c of the lid portion 16, the interval between the core material 42a of the peripheral wall portion 10 and the core material 42d of the bottom surface 21, and two adjacent cores of the peripheral wall portion 10. The space between the materials 42b is 180 at a portion where there is no core material when the core materials 42a, 42b, 42c, and 42d are vacuum-sealed and sealed between the two rectangular jacket materials 43. So that the vacuum heat insulating material 41 becomes 2 to 2.5 times as long as the vacuum heat insulating material 41 so that the core wall 42a of the peripheral wall portion 10 and the peripheral wall portion 13 can be bent. The space | interval with the core material 42b leaves the space | interval of the length of 3 to 3.5 times the thickness of the vacuum heat insulating material 41 when it becomes the vacuum heat insulating material 41. As shown in FIG.

  Next, as shown in FIG. 12, another rectangular outer covering material 43 is placed on one rectangular outer covering material 43 on which core members 42a, 42b, 42c, and 42d are placed. As shown in FIG. 2, when the inner space of the two jacket materials 43 is decompressed, and there is no core material 42a, 42b, 42c, 42d between the two jacket materials 43, the vacuum insulation material 41 is obtained. All the jacket materials 43 at the portion where the two jacket materials 43 are in close contact with each other at atmospheric pressure are thermally welded. As a result, when there is no core material 42a, 42b, 42c, 42d between the two jacket materials 43 to form the vacuum heat insulating material 41, a seal is provided at a portion where the two jacket materials 43 adhere to each other at atmospheric pressure. A portion 44 is formed.

  At the time of this thermal welding, the core materials 42a, 42b, 42c, and 42d are provided between the two jacket materials 43 so that the two jacket materials 43 are brought into close contact with each other by a fluid such as soft solid or air. Pressurize including a certain part.

  Next, as shown in FIG. 14, an unnecessary portion of the seal portion 44 that protrudes from the unfolded shape of the cold insulation container 1 (the unfolded shape of the connection portion between the peripheral wall portion 10 and the peripheral wall portion 13). (Cut along the dashed line in FIG. 13).

  Next, both surfaces of the vacuum heat insulating material 41 shown in FIG. 14 are covered with the sheet material 30, and the vacuum heat insulating material 41 and the sheet material 30 are fixed by an adhesive, an adhesive tape, sewing, etc. The peripheral wall portion 13 is connected by sewing or the like.

  In addition, even if it covers the single side | surface of the vacuum heat insulating material 41 with the sheet material 30 without covering both surfaces of the vacuum heat insulating material 41 shown in FIG. You may comprise.

  When the cold insulation container is configured only by the vacuum heat insulating material 41 without the sheet material 30, as shown in FIG. 15, one end portion serving as a peripheral wall portion and the other end portion are connected to provide a connecting portion 45. The portion that becomes the peripheral wall portion of the vacuum heat insulating material 41 is formed into a cylindrical shape.

  Here, as a structure which connects the connection part 45, the structure which superimposes the seal parts 44 of the vacuum heat insulating material located in a connection part, and joins with an adhesive agent, for example, overlaps and welds the seal parts 44 together. It is possible to adopt a configuration and a configuration in which the seal portions 44 are overlapped and sewn together.

  Next, as shown in FIG. 16, the portion that becomes the bottom surface portion of the vacuum heat insulating material 41 (the portion with the core material 42 d) is bent 90 degrees toward the inside of the cylinder, so that the cold insulating material constituted only by the vacuum heat insulating material 41 A container is made. FIG. 16 shows a state in which a portion that is a lid portion of the vacuum heat insulating material 41 (portion where the core material 42c is present) is bent 90 degrees outside the cylinder.

  Next, how to fold the cold insulation container composed of only the vacuum heat insulating material 41 shown in FIG. 16 will be described. FIG. 17 shows a portion (portion with the core material 42 d) of the vacuum insulating material 41 on one side (left side in FIG. 17) as a peripheral wall portion of the vacuum heat insulating material 41 (portion with the core material 42 a). A portion (portion with the core material 42c) of the vacuum heat insulating material 41 on one side (left side in FIG. 17) of the vacuum heat insulating material 41 is overlapped on the inner side (portion with the core material 42a). The state of being overlapped on the outside is shown, and the other side (the right side in FIG. 17) is also the bottom part of the vacuum heat insulating material 41 (the part with the core material 42 d) and the lid of the vacuum heat insulating material 41. The portions (portions with the core material 42c) are overlapped on the inside and outside of the portions (portions with the core material 42a) that respectively become the peripheral wall portions of the vacuum heat insulating material 41, and as shown in FIG. The part to be the peripheral wall part (the part with the core material 42b) is bent inside the cylinder.The thickness of the cold insulation container at the time of folding is 8 times the thickness of the vacuum heat insulating material 41.

  When the peripheral wall portion, the bottom surface portion, and the lid portion are constituted by the integral vacuum heat insulating material 41, a high cold insulation performance is expressed, the material cost is low, the wall thickness is thin, the volumetric efficiency is high, and the cold insulation container can be made compact when folded. In addition, it is possible to easily assemble and fold in a short time without requiring the trouble of removing some members such as a vacuum heat insulating material as in the case of a conventional cold container. Thereby, delivery work can be performed efficiently and transportation and storage after use are also easy. The strength and rigidity of each surface is high, and the strength and rigidity when assembled into a box body are improved.
