Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a cold storage container,
In particular, the present invention relates to a cold storage container suitable for housing fish and the like.

[0002]

2. Description of the Related Art Conventionally, insulated containers for storing fish and shellfish, etc., which have only a hole at the bottom of the container body, are closed during storage or transportation. The upper surface of the side wall of the container body, for example, as disclosed in Utility Model No. 3043521, so that the thawed drainage in a case where a plurality of stages are stacked in a state where the container is in From the lower container to form a through-hole downward, and also formed a through-hole that matches this with the lid body, and drained straight from the upper container to the lower container, but in this case,
Since the air flows freely in a straight line in the drainage path, there remains a problem that sufficient cooling performance cannot be exhibited.

[0003] In view of the above, an object of the present invention is to provide a cold storage container which can solve the above-mentioned problems.

[0004]

According to the cold storage container of the present invention which can solve the above-mentioned problems, as described in claim 1, a container body made of a foamed synthetic resin and a container body are provided. A container made of a foam synthetic resin lid that fits tightly, and in a state where the lid is fitted to the container body, the container is configured to be stacked and used,
A through hole is formed in the container body downward from the upper end surface of the side wall and opened at the lower end surface, and a first through hole is formed in the lid at a position corresponding to the through hole. Has at least one through drainage hole,
A second through hole is formed at a position corresponding to the drain hole when the containers are stacked in a state in which the lid is fitted to the container main body, and the container main body is formed at an upper end portion of a side wall of the container main body. A drainage channel is provided for communicating the above-mentioned through hole with the second through hole of the lid.

[0005] In the cold storage container of the present invention having the above structure, when the ice stored together with the fish and shellfish in the container main body is melted when the ice is stored in a plurality of stages, it passes through the drain hole of the container main body.
Through the second through-hole formed in the lid of the lower container,
The water is drained from the through-hole that opens downward at the lower end face from the upper end of the side wall of the container body through the drainage channel at the upper edge of the side wall of the container body that communicates with the second through-hole. Therefore, the drainage path does not descend straight, but is bypassed and drained by the drainage path of the container body, so that the air does not flow freely and is shut off. It will be able to demonstrate.

Further, according to the present invention, as set forth in claim 2, the through hole of the container body is formed at the corner of the upper end surface of the side wall, and the drain hole is formed slightly shifted inward from the corner of the bottom. Wherein the first through hole of the lid is formed at a position corresponding to the drain hole of the container body, and the second through hole is formed at a position corresponding to the drain hole of the container body.
Since the drain hole of the upper container body and the second through hole of the lid of the lower container can communicate with each other, the waste water is discharged from the second through hole through the drain passage of the container body according to claim 1. Water is passed down through the through hole formed in the corner of the container body to the first through hole of the lower lid, so that communication from the upper container to the lower container is achieved, and the containers are multistaged. Even if they are stacked, the water can be sequentially drained to the lower container side.

[0007]

Next, an embodiment of the present invention will be described below with reference to the drawings. In the perspective view of FIG. 1, 10 is a container body, 20 is a lid,
Both are made of a foamed synthetic resin, and the container body 10 and the lid 20 are formed on the upper end of the side wall of the container body 10 and the inner peripheral portion of the lid 20 by the fitting portions 11 and 21 formed by unevenness. Are formed so that they can be closely fitted to each other. In addition, when the containers are stacked in a plurality of stages in a state where the lid 20 is fitted to the container main body 10, at least a part of the bottom of the upper container main body 10 and the upper surface of the lower lid 20 are not displaced. A concave portion and a convex portion for preventing displacement may be formed, or a fitting structure in which the fitting portion 12 and the fitting portion 22 are formed as shown in the drawing.

The above-mentioned fitting structure of the container body 10 and the lid 20 is useful for preventing outside air from entering a drainage path described later. 13 in FIG. 1 and FIG. 2 showing a cross section of the corner,
2 shows a through-hole formed downwardly from the upper end face of the base member and opened at the lower end face. The through-holes 13 are formed at corners, specifically, at the four corners shown in FIG. First through holes 23 are formed at four corner positions corresponding to the through holes 13. Further, in FIG. 3, which shows a cross section of the container body 10 at the position of the drain hole, 15 is the container body 10
At least one at the bottom 16 of the
A drain hole formed in a penetrating part, which is formed at a position slightly shifted inward from the four bottom corners, and a second penetrating hole is formed in the lid 20 at a position corresponding to the drain hole 15 when the containers are stacked. A hole 25 is formed, and a drainage channel 17 communicating the second through hole 25 and the through hole 13 of the container body 10 is formed in a groove shape at the upper end of the side wall of the container body 10. .

Therefore, when the container body 10 with the lid 20 is stacked in two or more stages, the drainage in the container body 10 descends from the drain hole 15 of the container body 10 and the lower lid 2
0 through the drain passage 17 formed in the container body 10 of the lower lid 20 through the second through hole 25 of the container body 10.
Through the through-holes 13 at the four corners, through the first through-hole 23 of the lid 20 at the lower position and the through-hole 13 of the container body 10, and sequentially drain down to the lowermost container body 10. The water is drained from the through hole 13 of the main body 10 to the outside.

The second through-hole 25 of the lid 20 is formed so that a portion serving as a receiving portion 26 around the second through-hole 25 is formed in an inclined shape as shown in FIG.
It is preferable that the drainage channel 17 of the container body 10 is inclined in the drainage direction. Further, the container body 10 and the lid 2
As the foamed synthetic resin forming 0, a molded product obtained by in-mold foaming using pre-expanded particles as a raw material is suitable, and it can be carried out using expanded polystyrene or other known foamed synthetic resins.

[0011]

As described above, according to the present invention, when containers are stacked and stored or transported, water from the fish and shellfish contained in the container body and water due to melting of ice are drained. From the drain hole once shifted to a different position from the through hole of the container body, through the second through hole of the lid of the lower container,
Furthermore, since the water is drained to the through hole of the container body through the drainage passage of the container body corresponding to the lid body, there is no danger that the outer surface of the container with the lid body is contaminated with the drainage, and the drainage is linear in the vertical direction. Since the air is not once drained and is once bypassed, the air does not flow freely and is shut off, so that sufficient cooling performance can be exhibited, and particularly, it is possible to provide a suitable product as a cooling container for fish and shellfish. .
