Abstract

(57) [Summary] [Problem] The present invention is a cold storage container developed especially for transferring and storing fish and shellfish, which is easy to produce, and
It is intended to be provided at low cost. The present invention relates to a synthetic resin container comprising a foamed synthetic resin container body 1 and a sheet-shaped thin lid 2 covering the same, wherein an opening 3 of the container body 1 is provided on the lid 2.
The recess 5 is formed so as to be in close contact with at least some portions of the upper inner peripheral surface 4.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention particularly relates to the improvement of cold storage containers for transporting and storing fish and vegetables, and aims to provide a cold storage container that is easy to use and can be manufactured at low cost.

[0002]

[Prior art]

 The foam synthetic resin container is a material having a low specific gravity and excellent heat insulation properties.In the past, in many cases, ice and fresh fish or vegetables were stored in the container and used for transportation. is there.

[0003] However, conventional containers of this type are very closely fitted and are often difficult to remove. Was used.

[0004]

[Problems to be solved by the invention]

 The present invention has been developed in view of the above-mentioned issues. In many cases, trucks and refrigerated trucks were loaded and transported. In such cases, the top container was often capped and the other containers were often transported without a lid. However, in these cases as well, it has been considered that even simpler lids can adequately fulfill their role.

In this case, it is preferable that the lid is as small as possible, and development of a new product has been awaited in this respect as well as in terms of economic effects.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, a container made of a thick foamed synthetic resin container and a thin sheet-shaped lid covering the container body are provided. The recess is formed so as to be able to come into close contact with at least a part of the surface, or the recess is formed in the lid so as to be able to contact the entire upper inner peripheral surface of the container body.

[0007]

[Embodiment of the invention]

 A first embodiment of the present invention will be described in detail with reference to FIG. 1. A container body 1 made of a foamed synthetic resin and a sheet-shaped thin lid 2 covering the container body 1 are provided. A recess 5 is formed over the entire upper inner peripheral surface 4 of the opening 3 of the container body 1 so as to be able to be fitted closely.

In this case, as shown in FIG. 3, it is conceivable that the recessed portion 5 b of the lid 2 does not entirely contact the inner peripheral surface 4 of the opening 3 of the container body 1 but partially contacts the inner peripheral surface 4.

Further, as for the shape of the recessed portion 5 which can be fitted tightly over the entire upper inner peripheral surface 4 of the opening 3 of the container body 1, as shown in FIG. It is conceivable that the entire surface is formed as the recessed portion 5, or as shown in FIG. 2, it is formed into the groove-shaped recessed portion 5a.

Further, as shown in FIGS. 4 (A), 4 (B), 4 (C), 5, 6, and 7, cuts 6, 7, 8, etc. directed inward from the outer periphery of the lid. And the notches 12, 10, 11, etc. are formed between the cuts, and the corresponding cutouts 12,... Are provided in the container body 1. May be engaged, and these combinations can also be used.

In addition, the container is not only rectangular but also square, or can be formed into various shapes such as a circle, an ellipse, and a polygon, and of course, can be easily used.

In addition, various combinations of the above-described configurations are conceivable.

Also, when several recessed parts 5 are formed, when the container is rectangular, it may be provided on each of four sides or only on two sides. Combinations, etc. are also conceivable.

As the material of the thin lid 2, any material may be used. However, in order to make the lid 5 thin in sheet form, the material is made of polystyrene paper and this is made of foam sheet. By forming the lid into a thin lid, a product with extremely high elasticity and good heat insulation can be obtained, and the product can be manufactured more easily and at a low cost.

Further, any material can be used as the material of the container body 1 as long as it has excellent heat insulating properties, but styrene foam is preferable.

[0016]

[Effect of the invention]

 Since the present invention is configured as described above, it is easy to manufacture, and by forming it into a foamed sheet, a product with extremely high elasticity can be obtained, and it can be manufactured at a low cost. In this case, since it is less bulky than conventional products, it has the effect that many containers can be transferred.
