Description

[Detailed Description of the Invention] The present invention relates to a cold storage container made of a foam with a plastic skin layer.

Foam containers with a plastic skin layer are
A mold resin equal to the weight of the product was placed in a two-part closed mold, heated in a melting furnace while simultaneously rotating in an anisotropic direction, and the resin was evenly adhered to the inner wall of the mold. It is produced by injecting a foaming material into a hollow body (so-called outer skin) and foaming it, so it has the features of being lightweight and having a high cold-retention ability.

However, on the other hand, (a) metal fittings such as handles and hinges cannot be firmly attached, and (b) when the handle is screwed or glued to the outer skin, the handle cannot be attached to the outer skin. If pulled in the right angle direction, the outer skin of the handle part will peel off from the foam, resulting in damage.

That is, the outer skin of a foam with an outer skin is thin and has extremely low adhesion to the foam, resulting in the above-mentioned drawbacks (a) and (b).

The inventors of the present invention devised a cold storage container with a reinforcing plate in which metal fittings such as handles and hinges are simply and firmly attached to a container made of a foamed material with a plastic skin layer, which has the above-mentioned drawbacks.

To explain this with reference to the drawings showing an embodiment of the present invention, 1 is a container body, 2 is a lid made of foam with an outer skin or other suitable material, and the container can be opened and closed freely by a hinge 13 and a male screw 14. attached to the main body.

Reference numeral 3 represents a skin layer of a hollow body formed by rotary molding of a composite resin for a precept mold, and 4 represents an outer skin layer.

5 is a foamed material injected into a hollow body consisting of a skin layer.

A indicates an insert member, and the insert member consists of a metal reinforcing plate 6 and a metal support rod 7 firmly fixed to the reinforcing plate.

It is also possible to provide two or more reinforcing plates 6 as shown in FIG. 5, and it is also possible to provide foam inflow holes 10 in the reinforcing plates as shown in FIG. 3.

A female thread 9 or a male thread 9' is provided at the tip 8 of the support rod 7, and by providing this thread, handles, hinges, etc. can be easily attached.

When the female thread 9 is provided, the tip 8 of the support rod 7 is attached so as to be flush with the outer skin layer 4, and when the female thread 9 is provided, the tip 8 of the support rod 7 is provided so as to protrude from the outer skin layer.

11 indicates a board with a handle, 12 indicates a net handle,
The plate is firmly fixed by a female screw 9 and a male screw 14 provided at the tip 8 of the support rod 7.

The structure of the cold insulating container with a reinforcing plate according to the present invention is as described above, but this container can be manufactured in the following manner, for example.

First, a rotary molding die having an insertion hole through which an insertion member can be easily inserted into a desired location as shown in FIGS. 3 to 5 is prepared.

Next, a molding core is prepared which is removably fixed at the tip of the insertion member as shown in FIGS. At the same time, a suitable resin for the precept mold is charged into the mold.

Thereafter, a hollow body consisting of a skin layer with an insertion member is molded by a normal rotational molding method.

Next, foaming injection holes are bored at appropriate locations in this hollow body, and a foaming material is injected through the holes to foam inside the hollow body.

After the foam has hardened, metal fittings such as handle plates and hinges are attached to the tips of the support rods, thereby completing the cold storage container with reinforcing plates according to the present invention.

The structure of the cold storage container with reinforcing plate according to the present invention is as shown diagonally above.
Since the female thread or male thread is firmly fixed in the outer skin layer, metal fittings such as plates and hinges can be fixed very easily and firmly using the male thread or nut. play.

In addition, since the cold storage container according to the present invention has a reinforcing plate firmly fixed to the support rod inserted into the foam, even if the handle is pulled against the shell in a direction perpendicular to the outer shell, , the reinforcing plate, the foam, and the outer skin work together to provide an immeasurable effect of sufficient durability.

Therefore, it can be said that the cold insulating container with a reinforcing plate according to the present invention is a cold insulating container that has solved the above-mentioned (a) and (b), which are the weak points of cold insulating containers made of foam with an outer skin. .
