Description

  TECHNICAL FIELD The present disclosure relates to a cooler, cargo and transport equipment, a transportation method, and a cooler method.

  BACKGROUND ART A cold-preserving agent (coolant, ice pack) used for transporting food or the like in a cold state is known (for example, Patent Document 1). In addition, although the word "cold storage agent" conventionally refers to the whole including the container which enclosed not only the cold storage agent but the cold storage agent, in the present disclosure, the cold storage agent refers to the cold storage agent itself. The cold-preserving agent and the whole container enclosing the cold-preserving agent are referred to as a cold-keeping tool.

  A cold storage agent is usually regarded as a drug. For example, a cooling agent of a generally commercially available cooling tool is constituted by adding various additives to water. Additives include, for example, preservatives, freezing point depressants, thickeners, antifreeze, and colorants. Also, the container is in the form of a bag (a container having flexibility) or a box (a rigid container). As the material of the container, a resin with or without flexibility is used.

  Then, the cold insulator is, for example, a freezer to freeze the cold insulator, and is packaged together with the object to be cooled (for example, food). The temperature of the freezer is generally in the range of -20 ° C to 10 ° C, and the cryoprotectant is then at the start of use at a temperature of -20 ° C to -10 ° C.

JP, 2017-128622, A

  In the conventional cold-retaining tool, it is difficult to cool a cold-keeping object for a long time. As a result, for example, long distance transportation of the object to be cooled is difficult. In another point of view, a large amount of a cold storage agent is required for long-term cold storage, which in turn causes an increase in transport weight. Therefore, it is desirable to provide a cold insulator, a cargo, and a transport device that can extend the time of cold insulation.

  The cold-retention tool which concerns on 1 aspect of this indication has a paper pack and the ice of -100 degrees C or less enclosed with the said paper pack.

  In one example, the ice of -100 ° C or less is a frozen beverage.

  In one example, the beverage is refrigerated.

  In one example, the paper pack is a gable top, a brick type container or a tetra type container.

  The cargo according to an aspect of the present disclosure includes the above-described cold-preserving tool, a cold-keeping target, and a container that accommodates the cold-keeping tool and the cold-keeping target together.

  The transport apparatus according to an aspect of the present disclosure includes a container that contains the above-described cold-storage tool, a cold-storage target, and both the cold-storage tool and the cold-storage target.

  The transportation method according to an aspect of the present disclosure is a transportation method in which the object to be cooled and the cold storage device are accommodated in a container and transported, and the cold storage device is enclosed in a paper pack and the paper pack At least the contents which become ice of -100 ° C. or less when the above-mentioned cold insulator is housed in the container.

  A cold storage method according to an aspect of the present disclosure is a cold storage method for storing both an object to be stored and a cold storage tool in a container, wherein the cold storage tool is enclosed in a paper pack and the paper pack. The contents which become ice below -100 ° C, when a cold preservation tool is stored in the above-mentioned container.

  According to the above configuration, it is possible to lengthen the time for cooling.

Fig.1 (a) is a perspective view which shows the external appearance of the heat-retention tool which concerns on embodiment of this indication. FIG.1 (b) is a typical sectional view in the Ib-Ib line of FIG. 1 (a). Fig.2 (a) and FIG.2 (b) are external appearance perspective views which show the other example of the shape of a cold-retention tool.

(Composition of a heat insulator)
In short, the cold-retaining tool 1 shown in FIGS. 1 (a) and 1 (b) is produced by freezing a commercially available beverage enclosed in a paper pack 3 while being enclosed in the paper pack 3 It is done. That is, the cold insulating tool 1 has a paper pack 3 and ice 5 enclosed in the paper pack 3.

  The shape of the paper pack 3 may be made appropriate. FIGS. 1A and 1B illustrate a so-called gable top in which a roof-like portion is formed on a rectangular parallelepiped main body portion. The gable top type paper pack 3 is opened as constituting a spout at one end side of the ridge of the roof as indicated by a two-dot chain line, for example (the seal is released). Although not illustrated, the paper pack 3 may be provided with a removable cap on the slope of the roof. Further, in the case of a relatively small size (for example, for 200 ml), the paper pack 3 may be provided with a straw insertion port for inserting a straw on the slope. The size of the paper pack 3 (cooler 1) may be set as appropriate. In general, the gable top is often used to enclose 500 ml or 1 liter of beverage, and the paper pack 3 may be sized as well as such gable top.

  The paper pack 3 is made of a relatively thick paper material (milk carton paper) which is waterproof (water resistant). Such a paper material has, for example, a paper (carton paper) in a narrow sense (not shown), and a water impermeable layer covering both sides of the paper. Paper is made of a material and thickness capable of securing the strength that can constitute a box-like container, and is generally relatively thick. The impermeable layer is formed, for example, by coating or laminating polyethylene on paper.

  The ice 5 has a temperature of at least -100 ° C. (eg, about -120 ° C.) at least at the start of use of the cold preservation device 1 (eg, when packed with a material to be kept cold) or immediately before (eg, within 10 minutes of the start of use). It is assumed. Such ice 5 of -100 ° C. or less can be produced, for example, by using “ultra-low temperature chiller cold wave” manufactured by ADD Co., Ltd. The ultra-low temperature chiller can cool a supplied gas (eg, air, fluorocarbon gas, liquid nitrogen or argon gas) to a temperature of about -130 ° C. by using a multistage evaporator and a mixed refrigerant. Then, for example, by supplying the gas cooled by the above-described chiller around the cold insulator 1, it is possible to produce the ice 5 of −100 ° C. or less. Of course, the cold insulator 1 may be cooled by a freezer to which such a chiller is applied to realize ice 5 of -100 ° C or less.

  The lowest temperature measured on the earth is said to be around -90 ° C in Antarctica. Therefore, for example, even in the extremely cold region, even if the beverage sealed in the paper pack is frozen, there is no case that the cooling tool 1 of the present embodiment has already been produced (implemented) unintentionally. In general households, there is a possibility that a paper pack containing a beverage is put in a freezer in order to carry the beverage in a cold storage condition or to eat a frozen beverage. However, as already mentioned, the common freezer temperature is -20 ° C to -10 ° C. Therefore, again, there is no such thing that the cooling tool 1 of the present embodiment has already been implemented unintentionally.

  The type of beverage to be the ice 5 may be various known ones. For example, the beverage can include water, tea (such as green tea or black tea), coffee, juice, milk drink and sake. In addition, in another aspect, the beverage may generally be one that does not require refrigeration, or may be one that requires refrigeration. Examples of beverages that need to be refrigerated include milk drinks, fruit juices, vegetable juices and fresh sake. As a milk drink, milk, soya milk, yoghurt drink and lactic acid bacteria drink can be mentioned, for example. As understood from the above, the ice 5 does not have to be pure water frozen.

  Generally, in the gable top, a gas (for example, nitrogen) is also enclosed along with the beverage in a volume that roughly corresponds to the volume of the roof portion. Therefore, the position of the gas (the detailed shape of the ice 5) changes depending on the posture of the cooling tool 1 when the beverage is frozen to produce the ice 5. The position of the gas may be at any position in the paper pack 3.

(Use of a heat insulator)
The method of using the cold-preserving tool 1 may be the same as, for example, a well-known cold-preserving tool. For example, although not shown in the drawings, both the object to be cooled and the cooling implement 1 are packaged in a relatively small container (for example, 1 m or less × 1 m or less × 1 m or less) made of a heat insulating material (for example, expanded polystyrene). Transport the object for cold storage together with this container. In addition, you may only perform cold insulation, without transporting. Also, for example, in a container having a heat insulation structure (for example, one provided in a cold-storage car or a simple cold-storage car, the container is also an example of a container), a plurality of cold-storage tools 1 and one or more cold-storage objects May be housed together.

  As an object to be cooled, for example, food can be mentioned. As food, for example, frozen food, frozen confectionery, fresh food, dairy products and fresh food can be mentioned. Frozen food is a food which is frozen for the purpose of long-term storage, and may be non-heated, cooked, cooked, cooked or the like before freezing. As a frozen confectionery, an ice cream can be mentioned, for example. As raw confectionery, a cake can be mentioned, for example. As a dairy product, for example, yoghurt can be mentioned. As fresh food, for example, fresh fish (fish and shellfish), meat (meat) and fruits and vegetables can be mentioned. Also, the object to be stored cold may be a beverage of another type or the same type as the beverage serving as the ice 5.

  In addition, as an object to be cooled, for example, an organ for transplantation and a vaccine (an organ for transplantation or a container in which the vaccine is sealed) can be mentioned besides food and beverage. Although the word cold storage is generally used for foodstuffs, as understood from the above-mentioned examples, in the present disclosure, the material to be cooled is not limited to foodstuffs.

  The combination of the object to be cooled, the cooling tool 1 and the container in which these are housed together is an example of the cargo of the present disclosure. The cargo (container) may be relatively small or larger so that it can be carried by one person or a small number of people (manually). For example, as the former container, as already mentioned, the container which consists of expanded polystyrene can be mentioned. The latter container may include, for example, a container transported by a container ship or the like.

  The transport device transporting the above-described cargo, or a vehicle in which the object to be cooled and the cold storage device 1 are both accommodated in a built-in container is an example of the transport device of the present disclosure. In addition, as a transport apparatus, an aircraft, a train, a ship, and a two-wheeled vehicle can be mentioned other than a car.

  As described above, in the present embodiment, the cold-keeping implement 1 includes the paper pack 3 and the ice 5 of -100 ° C. or less sealed in the paper pack 3. In another aspect, the cargo includes a cold-keeping tool 1, a cold-keeping target, and a container that contains both the cold-keeping tool 1 and the cold-keeping target. In still another aspect, the transport apparatus includes a cold-keeping tool 1, a cold-keeping target, and a container that houses the cold-keeping tool 1 and the cold-keeping target together. In still another aspect, the transportation method is a transportation method in which both the object to be cooled and the cold-keeping device 1 are accommodated in a container and transported, and the cold-keeping device 1 is enclosed in the paper pack 3 and the paper pack 3 And the contents which become ice of -100 ° C. or less when at least the cold insulator 1 is housed in the container. In still another aspect, the method for keeping cold is a method for keeping both the object to be kept cold and the cold-keeping tool 1 in a container, wherein the cold-keeping tool 1 is enclosed in the paper pack 3 and the paper pack 3 The contents which become ice of -100 ° C or less when the cold preservation implement 1 is stored in a container.

  Here, ice of -100 ° C or less has a longer time to melt as compared to normal ice (eg, -20 ° C to -10 ° C). As a result, for example, the object to be insulated can be cooled for a long time. In another aspect, the amount of ice required for transport can be reduced. As a result, the weight to be transported can be reduced, and the transportation cost can be reduced.

  Specifically, in experiments conducted by the present applicant, it was found that ice at -100 ° C or less takes about three times the time to completely melt as compared to normal ice. That is, it was found that by using ice at -100 ° C. or less, the time for keeping cold can be approximately tripled compared to when using the same amount of normal ice. In another aspect, it has been found that the amount of ice required to maintain the cooling effect for a predetermined time can be reduced to 1/3. Therefore, for example, in the case where 3 kg of a normal cold insulator is used for transporting 10 kg of food, the weight of the cold insulator 1 may be 1 kg if the cold insulator 1 of the present embodiment is used. That is, the transport weight is reduced by about 15%. As a result, transportation costs can be reduced.

  Moreover, since the container in which the ice of -100 ° C or less is sealed is the paper pack 3, it is easy to seal the ice 5 of -100 ° C or less. Specifically, in an experiment conducted by the present applicant, the package was broken when the flexible resin package was cooled and the content was iced below -100 ° C. Moreover, when the pet (PET: polyethylene terephthalate) bottle was cooled and the content was made into ice below -100 degreeC, the plastic bottle was damaged. On the other hand, when the paper pack was cooled and the content was iced at -100 ° C. or less, the paper pack did not break and the sealability was maintained.

  And since the ice 5 of -100 ° C. or less can be sealed by the paper pack 3, for example, the possibility that the ice 5 is melted and the liquid generated may leak is reduced. As a result, the possibility that the object to be cooled may be contaminated by the leaked liquid is reduced. In another aspect, the need for dedicated components to reduce contamination is reduced. Also, the contents of the paper pack 3 can be frozen again to reuse the heat insulating device 1. Furthermore, the contents of the paper pack 3 can be used for other purposes.

  Moreover, in this embodiment, the ice 5 of -100 degrees C or less is what frozen the drink. Therefore, for example, the cold insulator 1 can be configured by what can be the transport object itself. As a result, it is possible to reduce the transport weight (shipping cost) by reducing the need to transport a cooler that is separate from the transport object only for the purpose of cold storage.

  In particular, in the case where the beverage needs to be refrigerated, a cooler is not required to cool the beverage, and therefore, the transport weight (transport cost) is reduced compared to the case where the conventional cooler is used. Quantity increases.

  Further, in the present embodiment, the paper pack 3 is a gable top. Therefore, it is possible to cool the product which is generally marketed and which is obtained by sealing the beverage in the paper pack 3 to produce the cold insulator 1. Therefore, it is not necessary to make the paper pack 3 by custom order, and the cost can be reduced. In another aspect, the cooling tool 1 becomes a retailable beverage product as it is (without transferring the contents to another container) after being used for cooling the object to be cooled. Therefore, the cost can be reduced.

(Other examples of paper pack shape)
The shape of the paper pack of the cold insulator may be, for example, various known ones. Below are some examples.

  The paper pack 13 of the cold insulator 11 shown in FIG. 2A is a so-called brick type container. That is, the paper pack 13 is formed in a substantially rectangular parallelepiped shape. The rectangular parallelepiped may be, for example, of a thin type (example in the drawing) in the front and back, or a long type in the vertical direction.

  In the illustrated example, a relatively small (for example, 200 ml) brick type container is assumed, and the paper pack 13 has an insertion port 15 for inserting a straw. The insertion port 15 is closed by, for example, a film having a strength lower than that of the other portion of the paper pack 13. Then, the paper pack 13 is opened by forming a hole in the film by the straw.

  In addition, the insertion port 15 may be covered by the peeled part of the paper pack 13. In addition, the paper pack 13 (particularly, a relatively large one) may be opened by peeling off the seal closing the opening, and the contents may be poured from the opening, or part of the paper pack 13 may It may be cut off and opened.

  The paper pack 23 of the cooling tool 21 shown in FIG. 2B is a so-called tetra-type container. That is, the paper pack 23 is formed in a substantially triangular pyramid shape. In the illustrated example, a relatively small (for example, 200 milliliters) tetra-type container is assumed, and the paper pack 23 has an insertion port 25 for inserting a straw.

  The role of the insertion slot 25 is the same as that of the insertion slot 15 of FIG. 2 (a). Further, as in FIG. 2A, the insertion port 25 may be covered by the peeled portion of the paper pack 23, and the paper pack 23 peels off the seal closing the opening and opens it. It may be one that is partially cut away with scissors or the like and opened.

  In addition, in the cold insulators 11 and 21, like the cold insulator 1, the gas may be enclosed with the ice, or only the ice may be enclosed.

  The technology according to the present disclosure is not limited to the embodiments described above, and may be implemented in various aspects.

For example, the raw material used as ice of -100 degrees C or less is not limited to a drink. For example, the raw material may be a conventional coolant or may be water not suitable for beverages such as seawater. The cold insulator usually contains water (H ₂ O) but may not contain water. Similarly, the raw materials other than the heat insulating agent may not contain water.

  Also, for example, the paper pack is not limited to one having the same configuration as that for a commercially available beverage. For example, the paper pack may have a more specialized shape for cooling. For example, the paper pack may have a unique shape in accordance with the shape of the object to be cooled, or may have a shape having a recess for accommodating the object to be cooled. In addition, the paper pack may have designability in shape and the like so as to constitute all or part of the package of the object for cold storage for gift giving.

  In the description of the embodiment, the volume of the paper pack is mentioned in the range of 200 ml or more and 1 liter or less (strictly, for example, 1100 ml or less considering the presence of gas). However, the volume of the paper pack may be smaller or larger than this.

  The material and thickness of the milk carton paper making up the paper pack may also be configured differently to that for commercial beverages. The thickness may be set, for example, in the range of 5 μm or more and 2 mm or less, including the thickness of a commercially available product.

  1 ... a cooling tool, 3 ... a paper pack, 5 ... ice.
