[0014] 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

[0015] 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.

[0016] 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.

[0017] As shown in FIG. 2, the refrigerant storage structure 30 includes a storage section 32 that stores a refrigerant RA, and a condensation water recovery section 34 provided on the outer side of the storage section 32 and below the storage section 32.

[0018] As shown in FIG. 2 and FIG. 3, the storage section 32 has a cooling agent inlet / outlet 32a through which the cooling agent RA can be inserted and removed. In the embodiment, the cooling agent inlet / outlet 32a opens sideways and faces the front surface 16. The storage section 32 in the embodiment is large enough to arrange a plurality of cooling agents RA side by side. The storage section 32 is made of a storage section sheet S1 (see FIG. 5). The storage section 32 in the embodiment is bag-shaped with the upper, lower and rear edges of the storage section sheet S1 connected to the side surface 20 by sewing or the like. That is, the storage section 32 has a rear side opposite to the front cooling agent inlet / outlet 32a, which is closed. Thus, the storage section 32 has upper and lower surfaces, a side surface disposed at an interval from the side surface 20, and a rear surface, and the cooling agent RA placed on the lower surface is arranged between the side surface and the side surface 20. The storage section sheet S1 may be, for example, 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 deposition film, or a sheet of other material. The storage section sheet S1 of the embodiment is flexible.

[0019] As shown in Figs. 2 to 4, the condensed water recovery section 34 is provided on the outer side of the side surface of the storage section 32 and on the lower side of the storage section 32, and forms a space between the side surface and the lower surface of the storage section 32. The side surface of the condensed water recovery section 34 covers the outer side surface of the storage section 32, and the bottom surface of the condensed water recovery section 34 covers the lower side of the storage section 32. The bottom surface of the condensed water recovery section 34 extends outward beyond the side surface of the storage section 32. In the condensed water recovery section 34, an upper space between the side surface of the condensed water recovery section 34 and the side surface of the storage section 32 is connected to a lower space between the bottom surface of the condensed water recovery section 34 and the lower surface of the storage section 32. The distance between the condensed water recovery section 34 and the storage section 32 is not particularly limited, but it is preferable to set it to, for example, 1 mm or more.

[0020] The condensed water collecting section 34 has an opening 34a that opens sideways. The condensed water collecting section 34 has openings 34a formed on both the front and rear sides. Even if the condensed water collecting section 34 has an opening 34a that opens sideways, no articles are placed in front of or behind the cooling storage agent storage structure 30, so that even if the collected condensed water flows out from the opening 34a, there is no adverse effect on the articles. In the embodiment, the opening 34a is formed to open over the entire side of the condensed water collecting section 34, but this is not limiting, and the opening 34a may be formed to open at a position higher than the bottom surface of the condensed water collecting section 34 to make it difficult for the collected condensed water to flow out from the opening 34a.

[0021] The condensed water collection section 34 is composed of a collection section sheet S2 (see FIG. 5). The upper edge of the collection section sheet S2 is connected to the upper surface or upper side of the storage section 32 by sewing or the like, and the lower edge of the collection section sheet S2 is connected to the lower edge of the storage section 32 by sewing or the like, so that the condensed water collection section 34 is formed in a cylindrical shape that opens at the front and rear. Note that the condensed water collection section 34 of the embodiment is composed of one collection section sheet S2. The vertical dimension of the collection section sheet S2 is set to be longer than the dimension from the upper edge of the side of the storage section 32 to the lower edge of the storage section 32. When the upper edge of the collection section sheet S2 is connected to the upper side and the lower edge of the collection section sheet S2 is connected to the lower edge of the storage section 32, a slack is generated in the collection section sheet S2 by an excess length longer than the side and lower surface of the storage section 32, forming a space for the condensed water collection section 34.

[0022] The condensed water collecting section 34 may be made of a waterproof collecting section sheet S2. By making the condensed water collecting section 34 of the waterproof collecting section sheet S2, the condensed water received by the condensed water collecting section 34 can be prevented from passing through the collecting section sheet S2 and flowing out. In addition, the collecting section sheet S2 may have no or low breathability. As the collecting section sheet S2, for example, a plastic sheet such as a cloth of polyolefin resin such as polypropylene or vinyl chloride, a composite sheet of a plastic sheet and an aluminum vapor deposition film, or a sheet of other material can be used. Note that the storage section sheet S1 and the collecting section sheet S2 may be made of the same material or different materials. The collecting section sheet S2 of the embodiment has flexibility.

[0023] The hardness of the collection section sheet S2 itself allows the condensed water collection section 34 to maintain a shape that separates from the side and bottom surfaces of the storage section 32. The collection section sheet S2 of the embodiment has flexibility that allows it to deform when an external force is applied, but has enough hardness to maintain its shape when no external force is applied. The cooling storage agent storage structure 30 may maintain the space of the condensed water collection section 34 by arranging a support such as a sponge between the condensed water collection section 34 and the storage section 32.

[0024] As shown in Fig. 6, the cooling storage agent housing structure 30 may include a water absorbent 40 in the condensed water collection section 34. The water absorbent 40 may be a fibrous material such as cloth or nonwoven fabric, or a foam such as polyurethane foam, either alone or in combination. By providing the water absorbent 40 in the condensed water collection section 34, the condensed water received in the condensed water collection section 34 can be absorbed and held in the water absorbent 40. This also makes it possible to prevent the condensed water received in the condensed water collection section 34 from flowing out.

[0025] The storage section 32 itself is cooled by the cold storage agent RA stored in the storage section 32. In particular, the bottom surface of the storage section 32 on which the cold storage agent RA is placed and the side surface of the storage section 32 that is likely to come into contact with the side surface of the cold storage agent RA are cooled. For this reason, condensation may occur on the side surface and bottom surface of the storage section 32. According to the cold storage agent storage structure 30 of the embodiment, the condensed water recovery section 34 is provided on the outer side surface of the storage section 32 and on the lower side of the storage section 32, so that even if the condensation generated on the outer side surface of the storage section 32 and the bottom surface of the storage section 32 splashes toward the article side due to vibration during transportation, the condensed water recovery section 34 can receive the condensed water. In addition, even if the condensation generated on the outer side surface of the storage section 32 flows down along the outer side surface of the storage section 32, the condensed water recovery section 34 is also provided on the lower side of the storage section 32, so that the condensed water recovery section 34 can recover the condensed water generated on the outer side surface of the storage section 32 and the bottom surface of the storage section 32 and prevent it from splashing toward the article side.

[0026] Since a space is formed between the condensed water recovery section 34 and the side surface and the bottom surface of the storage section 32, the side surface of the condensed water recovery section 34 can be separated from the side surface of the storage section 32, and the bottom surface of the condensed water recovery section 34 can be separated from the bottom surface of the storage section 32. In this way, since the side surface and the bottom surface of the condensed water recovery section 34 are not in contact with the storage section 32, it is possible to prevent the side surface and the bottom surface of the condensed water recovery section 34 from being cooled by the cooling agent RA, and it is possible to avoid condensation from occurring on the side surface and the bottom surface of the condensed water recovery section 34.

[0027] Therefore, in the container 10 equipped with the cooling storage agent storage structure 30, it is possible to prevent the adhesion of condensation water to the items stored in the container 10, and to prevent adverse effects such as staining due to condensation water. In particular, in the case of the cooling storage agent storage structure 30 provided on the inner surface of the side surface portion 20 of the container 10, since it is disposed close to the side of the items stored in the container 10, preventing the scattering of condensation water generated on the outer side surface of the storage portion 32 is highly effective in preventing condensation water.

[0028] Since the condensed water recovery section 34 has an opening 34a that opens sideways, the air between the condensed water recovery section 34 and the storage section 32 that has been cooled by the refrigerant RA can flow out from the opening 34a to the article side. Since the air between the condensed water recovery section 34 and the storage section 32 can be exchanged to a certain extent in this way, it is possible to prevent the side and bottom of the condensed water recovery section 34 from being cooled by the refrigerant RA, and to prevent condensation from occurring on the side and bottom of the condensed water recovery section 34. Furthermore, since the opening 34a is provided, it is possible to clean the condensed water recovery section 34 and to insert and remove the water absorbent 40.
