DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Next, the cooling storage material storage structure and container according to the present invention will be described below with reference to preferred embodiments and the accompanying drawings. Note that the embodiments and drawings described below are merely examples of the present invention, and are not intended to limit the present invention to these configurations, and may be modified as appropriate without departing from the scope of the present invention. EXAMPLES

[0011] As shown in FIG. 1, a container 10 including a cooling storage material storage structure 30 according to the embodiment is box-shaped. The container 10 includes a top surface portion 12 forming a ceiling, a bottom surface portion 14 forming a bottom surface, a front surface portion 16 forming a front surface, a rear surface portion 18 forming a rear surface, and side surfaces 20, 20 forming left and right side surfaces. Each portion of the container 10 has a heat-insulating structure. Each portion of the container 10 is made of a material having good heat insulation properties, such as a heat-shielding sheet in which aluminum or the like is laminated on polyvinyl chloride or the like, or a foam such as polystyrene foam or hard polyurethane foam, either alone or in combination. The front surface portion 16 of the container 10 can be opened and closed. The front surface portion 16 of the container 10 is opened to insert and remove items. The container 10 is illustrated as being installed on a transport cart CA.

[0012] The refrigerant storage structure 30 is provided on the side surface 20 of the container 10. The container 10 has an internal space for storing items that is cooled by the refrigerant RA stored in the refrigerant storage structure 30 provided on the inner surface of the side surface 20.

[0013] 2 to 4, the refrigerant storage structure 30 includes a heat insulating layer 34. Specifically, the refrigerant storage structure 30 includes the heat insulating layer 34 on all or part of the surface that defines the storage space 32 that contains the refrigerant RA. When the refrigerant storage structure 30 is disposed on the inner surface of the side surface portion 20 of the container 10 as in the embodiment, it is preferable to provide at least the heat insulating layer 34 on the side surface and bottom surface of the refrigerant storage structure 30 as a measure against condensation.

[0014] In this way, the heat insulating layer 34 is preferably disposed on the bottom surface and the surface facing the article in the refrigerant storage material containing structure 30. If the refrigerant storage material containing structure 30 is disposed on the inner surface of the top surface 12 of the container 10, the heat insulating layer 34 is preferably disposed on at least the bottom surface, and if the refrigerant storage material containing structure 30 is disposed on the inner surface of the rear surface 18 of the container 10 with the refrigerant inlet / outlet 30a facing upward, the heat insulating layer 34 is preferably disposed on at least the bottom surface and the front surface.

[0015] 2 and 3, the cold storage agent storage structure 30 is formed in a bag shape having upper and lower surfaces, a side surface facing the inner surface of the container 10, and a rear surface, and has a cold storage agent inlet / outlet 30a at the front surface through which the cold storage agent RA can be inserted and removed. Thus, the cold storage agent inlet / outlet 30a opens sideways and faces the front surface 16. The cold storage agent storage structure 30 is bag-shaped with its upper, lower and rear edges connected to the side surface 20 of the container 10 by sewing or the like. That is, the storage space 32 is closed at the rear side opposite to the front cold storage agent inlet / outlet 30a. The storage space 32 of the cold storage agent storage structure 30 of the embodiment is large enough to accommodate a plurality of cold storage agents RA arranged in a front-to-rear arrangement.

[0016] 4, the upper and rear surfaces of the refrigerant storage material containing structure 30 are formed of a skin sheet 36. The upper and rear surfaces of the refrigerant storage material containing structure 30 may be formed of only one skin sheet 36, or may be formed of a multi-layer structure in which a plurality of skin sheets 36 (two in this embodiment) are stacked.

[0017] The side and bottom surfaces of the refrigerant storage material containing structure 30 are insulated with a heat insulating layer 34 disposed between two skin sheets 36, 36. The heat insulating layer 34 may be separate for each surface of the refrigerant storage material containing structure 30, or may be connected from the side to the bottom surface of the refrigerant storage material containing structure 30 as in the embodiment. The refrigerant storage material containing structure 30 of the embodiment is entirely formed of two skin sheets 36, 36, and the heat insulating layer 34 is disposed between the two skin sheets 36, 36 that form the side and bottom surfaces, making the heat insulating properties of the side and bottom surfaces higher than those of the top and rear surfaces. The side and bottom surfaces of the refrigerant storage material containing structure 30 are also thicker than the top and rear surfaces.

[0018] For example, foam-based insulation materials made of foam such as plastic cardboard, urethane foam, polystyrene foam, and phenol foam, vacuum insulation materials in which the air inside is removed to create a vacuum, and inorganic insulation materials such as glass wool and rock wool can be used alone or in combination as the insulation layer 34. From the viewpoints of insulation, rigidity, cost, and the like, it is preferable that the insulation layer 34 is made of a hard material, and among these, plastic cardboard is preferable.

[0019] The surface sheet 36 may be a plastic sheet such as a polyolefin resin such as polypropylene or a cloth such as polyvinyl chloride, a composite sheet of a plastic sheet and an aluminum vapor deposition film, or a sheet of another material.

[0020] When the cold storage agent RA is accommodated in the accommodation space 32, the portion of the cold storage agent accommodation structure 30 that has the insulating layer 34 is unlikely to be cooled. Condensation occurs in the cold storage agent accommodation structure 30 due to the temperature difference between the internal space of the container 10 and the cold storage agent accommodation structure 30. However, since the portion of the cold storage agent accommodation structure 30 that has the insulating layer 34 has high thermal insulation due to the insulating layer 34, the cold storage agent RA is unlikely to become cold even if placed in the accommodation space 32. Therefore, it is possible to prevent condensation from occurring in the portion of the cold storage agent accommodation structure 30 that has the insulating layer 34. In particular, in the case of the cold storage agent accommodation structure 30 that is provided on the inner surface of the container 10, if the insulating layer 34 is provided on the side surface and the bottom surface, it is possible to prevent condensation from occurring on the side surface and the bottom surface, and even if an item is placed close to the cold storage agent accommodation structure 30, it is possible to prevent the condensation water from splashing onto the item. In this way, according to the cold storage agent accommodation structure 30, condensation water is unlikely to occur, and therefore adverse effects on the surroundings caused by the condensation water can be prevented. Furthermore, the container 10 can prevent adverse effects of condensation on items.

[0021] Even if the refrigerant storage structure 30 has the insulating layer 34, the internal space RA can be cooled by cold air flowing out of the internal space of the container 10 from the heat storage agent inlet / outlet port 30a and the top and rear surfaces that do not have the insulating layer 34. Then, if the internal space of the container 10 is cooled and the temperature difference between the inside and outside of the refrigerant storage structure 30 becomes smaller, condensation in the refrigerant storage structure 30 becomes less likely to occur.

[0022] (Example of change) The present invention is not limited to the above, and may be, for example, as follows: Note that the present invention is not limited to the specific descriptions of the embodiment and the following modified examples. (1) The ice storage material containing structure may be integrally provided to the container by sewing or gluing, or may be a separate body that can be detachably attached by hook-and-loop fasteners or other fastening means. (2) The ice storage material storage structure may be provided on a portion other than the side of the container. For example, it may be provided on the rear or top of the container. When the ice storage material storage structure is provided on the rear of the container, the opening for inserting and removing the ice storage material may be oriented upward. (3) The container is not limited to the type installed on a transport cart, but may be any container that keeps items cool. (4) The container is not limited to being box-shaped, but may be bag-shaped or cover-shaped. [Explanation of symbols]
