Description

[Detailed Description of the Invention] The present invention relates to a storage container, and particularly to a container suitable for storing perishables such as perilla leaves.

Conventionally, wooden boxes or compressed-air vacuum-formed boxes made of plastic sheets have been used as containers of this type, but the former has drawbacks such as being heavy, expensive to manufacture, and not ideal for mass production of uniform products. However, the latter had problems such as weak strength and easy damage to the box.

The present invention was made to provide a new type of container that does not have the above-mentioned defects and is suitable for storing perishables.For this purpose, the container is made of a plastic sheet or film that is formed by air-pressure vacuum forming. A plastic foam hard wall of a constant thickness that approximately matches the wall surface is integrally and tightly formed on the peripheral wall surface of the container body, and the bottom of the container body is provided with ribs with grooves on the bottom outer side extending to the side edges. The structure is characterized in that the lower part of the foam hard wall has a configuration in which vent holes communicating with the concave spaces of the ribs are prominently shaped.

This will be explained in more detail below with reference to the drawings shown as an example.

The container 1 of the present invention is integrally formed with a container main body 2 formed by pressure-vacuum forming a plastic sheet or film and a peripheral wall 3 made of a hard plastic foam material.

The container main body 2 has protrusions 4 intermittently protruding from the bottom so that the inside of the main body is divided into a plurality of storage sections, and ribs 5 of the bottom inner protrusion, that is, the bottom outer concave strip extending to the side edges, are formed on the protrusions. 4, and the bottom 6, side wall 7, and upper edge 8 are integrally molded.

It is optional to form appropriate ribs or patterns on the outside.

Further, it is preferable to form retaining protrusions 9 at the four corners of the bottom 6 so as to project slightly downward.

The peripheral wall 3 has an appropriate thickness so as to provide sufficient strength to the entire container, has a height at least from the upper edge of the container body to the bottom, and has approximately the same height at the bottom so as to correspond to the ribs 5. 10 ventilation holes are formed at intervals.

Then, the upper surface of the peripheral wall 3 is joined to the lower surface of the upper edge 8 of the container main body, and this joined part is glued or fused to integrate the whole, so that the concave space of the rib 5 and the hole 10 communicate with each other. This is the container 1 of the present invention.

In this way, according to the container of the present invention, the main body of the container is made of a sheet or film formed by pressure-pressure vacuum forming, and the peripheral wall is made of foam, so the entire body is lightweight, and the peripheral wall firmly retains its shape. This makes it convenient to store and handle the containers, and it is also possible to transport them as is by stacking a large number of containers and tying them with strings, etc., which eliminates the need for a separate container for transportation such as a cardboard box, which is rational. .

The presence of the protrusion 9 is more effective for multi-stage stacking.

In addition, compared to wooden boxes or injection molded boxes, they are extremely lightweight and inexpensive to manufacture, and can be beautifully formed, so they are easy to use, and can be used not only for storage and transportation, but also when placed in stores as they are. Do not damage.

By forming the protrusions 4 and ribs 5, the inside of the container can be divided appropriately, making it easier to store.In the case of large leaves, the leaf body is placed in the compartment, and the stem is separated from the protrusions 4. 4
By placing the stored items in the gap between the ribs, the items can be stored in an orderly manner so that they do not move, and since the holes 10 in the peripheral wall of the concave space of the rib communicate as a ventilation path,
Even if the containers are stacked in multiple stages, ventilation can always be made inside and outside the box through the ventilation path, and even if perishables are stored, the stored items can be prevented from being damaged by stuffiness or the like.
