Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a container, and more particularly to a container whose main body is made of a single transparent plastic sheet and which has double side walls.

Conventionally, in the case of cup containers made from plastic sheets, it is difficult to print on the side wall, and if the container is deep, the side wall becomes thin, causing the container to become hot when used as a noodle container, causing problems in use.

The present invention is a container devised to overcome the drawbacks of these conventional containers and provide new performance.

As shown in FIG. 2, which is a cross-sectional view, the container of the present invention is made of a single transparent plastic sheet having double side walls; There is a double side wall consisting of the inner wall and an outer wall 5 around the content storage section 4 consisting of the inner wall 3, and a printed matter 7 is interposed between the side walls, and a connecting portion 8 and the outer side connect the double side wall. Cover the flange part 9 that connects to the wall (10 and 11)
This is a container 1 that is sealed.

The container of the present invention thus obtained does not require the technically difficult printing method of printing on the side wall or the high cost printing method of curved surface printing, unlike conventional containers, and can be printed on printed cardboard or plastic film. By interposing the content between the double side walls, the content display can be visually appealed to consumers.Furthermore, when relatively thick paper such as cardboard is interposed between the double side walls, the paper has a reinforcing effect. Since the plastic sheet is coated with a thin film, it can be used as a sturdy container even if the plastic sheet is not very thick.

Furthermore, since the container of the present invention has double side walls consisting of an inner wall and an outer wall, there is a space between the side walls, which creates a heat insulating effect and allows the container to be filled with contents at a higher temperature than conventional containers even if they are made of the same material. However, since there is no deformation of the outer part of the container and no warmth on the outer wall, the range of contents that can be filled is expanded, and the functionality of the container is increased compared to conventional single-layered containers.

Note that the material of the lid material may be any material as long as it has a sealing property with the container, and for example, in the case of a PP container, the sealing property of the lid material is good if the sealing surface is an EVA-based composite film.

As described above, the container of the present invention is formed by thermoforming a single plastic sheet into a container with double side walls, but it has the characteristics of a conventional container with a single side wall, and has a wide range of applications. wide.

[Brief explanation of the drawing]
