Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a cold box, and particularly to a cold box having a structure that can easily be brought into a cooling state.

[Conventional technology]

Conventional cold storage boxes, such as cashier coolers and cooler bags, have a structure in which ice, dry ice, cold storage material, or the like is placed inside the cold storage box to cool the contents.

[The problem that the idea aims to solve]

Conventional cold storage boxes do not store ice, dry ice,
Since cold storage materials are used inside the refrigerator, these cooling sources occupy a percentage of the volume inside the refrigerator, making it impossible to use the internal volume effectively. There was a problem that was different from the product.

There were also problems in that ice, dry ice, etc. had to be procured each time they were used, and cold storage materials had to be separately procured and precooled.

The purpose of this invention is to solve the above-mentioned problems.The inner container is formed using a cold storage material, and the inner container of the cold storage material has a structure that can be precooled alone or together with a part of the outer box. The purpose of the present invention is to provide a cold storage box with a structure that allows for effective use of the cold storage box.

[Means to solve the problem]

In order to achieve the above object, the cold storage box of the present invention is equipped with a detachable mechanism at the lower end, and has an outer box body whose inside is filled with a heat insulating material, and an upper end of the outer box body that can be opened and closed. At the same time, the lid body is filled with a heat insulating material inside, and the upper end is provided with a detachable mechanism that engages with the detachable mechanism provided at the lower end of the outer box body, and the inside is filled with a heat insulating material. The present invention is characterized in that it includes an outer box bottom body made of an outer box bottom body, and an inner container made of a cold storage material that is arranged on the inner wall of the outer box body and the outer box bottom body and forms a double wall structure.

The inner container may be separated independently, or the inner container and the outer box body may be integrated and separated from the outer box bottom. It is also possible to have a structure in which the outer box body is separated from the outer box body in an integrated form. The lid body is separated from the inner container at any time.

[Effect]

The inner container made of the cool storage material is placed alone or together with another outer box body or outer box bottom in, for example, a freezer to cool the inner container made of the cool storage material. After the inner container has been cooled, each outer box and lid are attached to the inner container, thereby creating a cold storage box that uses the inner container itself as a cooling source. This will be explained below with reference to the drawings.

〔Example〕

FIG. 1 is a longitudinal cross-sectional view of an embodiment of a cold storage box according to the present invention, and FIG. 2 is an exploded explanatory view thereof.

In FIGS. 1 and 2, reference numeral 1 denotes an outer box body, and the inside of the outer box body 1 is filled with a heat insulating material 2 that blocks heat conduction. A threaded portion 3 serving as an attachment/detachment mechanism is provided at the lower end of the outer box body 1. An outer box bottom body 4 is attached below the outer box body 1. The threaded portion 5 provided at the upper end of the outer box bottom body 4 is threadedly engaged with the threaded portion 3 of the outer box body 1, so that the outer box body 1 and the outer box bottom body 4 form an integrated outer box. It has a structure. The inside of the outer box bottom body 4 is also filled with a heat insulating material 6 to block heat conduction. Note that an annular packing 7 is placed at the joint between the outer case body 1 and the outer case bottom body 4.

An inner container 8 made of a cold storage material is provided on the inner wall of the outer box, which constitutes an integral outer box with the outer box body 1 and the outer box bottom 4. Therefore, the cold box is formed by the inner container 8.
It has a double wall structure with the outer box and the outer box. The inner container 8 and the outer case body 1 are integrated by means such as adhesive or fitting, and are separated from the outer case bottom 4 as shown in FIG.

Further, the upper end portion of the outer box body 1 is covered with a lid 9 that is engaged in an openable and closable manner.
The inside of the lid 9 is also filled with a heat insulating material 10 to block heat conduction. In addition, outer box body 1
An annular packing 11 is also placed on the upper end surface of the lid 9 to maintain close contact with the lid 9.

A metal fitting 12 for attaching a handle is provided on the side surface of the outer box body 1, and a handle 13 for carrying is attached to the metal fitting 12.

As is clear from FIG. 2, the inner container 8, which is integrated with the outer case body 1, is separated from the outer case bottom body 4 by the threaded parts 3 and 5 of the attachment/detachment mechanism, and can also be opened and closed with the lid body 9. Separated by gender. The inner container 8 with the outer box body 1 from which the outer box body 1, the lid body 9, and the handle 13 have been removed is placed in a freezer and cooled. After being sufficiently cooled, the frozen outer box body 1
By assembling the attached inner container 8 as shown in FIG. 1, it functions as a cold storage box. At this time,
The inner container 8 itself, which is made of a cold storage material, serves as a cooling source, and the inside of the cold storage box can be used effectively, and the displayed internal volume matches the practical internal volume.

In the above description and FIG. 2, the inner container 8 is integrated with the outer box body 1 and is frozen.
The structure may be such that the inner container 8 alone can be separated from the outer box, and only the inner container 8 may be frozen. Alternatively, the inner container 8 and the outer box bottom 4 may be integrated, and the outer box bottom 4 may be
The attached inner container 8 may be structured to be frozen.

Further, other attachment/detachment mechanisms may be used instead of the threaded portions 3, 5.

[Effect of idea]

As explained above, according to the present invention, since the double-walled inner container is made of cold storage material, the inside of the refrigerator can be used without wasting it, and there is no need to procure ice, dry ice, etc. . It can be used over and over again, reducing running costs.
