Description

[Detailed Description of the Invention] The present invention relates to the structure of a simple, basically single-use container for storing and transporting food products made of synthetic resin as a base material.

Conventionally, various types of containers made of synthetic resin materials have been known as such simple containers.

In particular, foamed synthetic resin materials such as styrofoam are often used, but due to problems in molding, the corners cannot be configured with acute angles, and the internal capacity is small compared to the external shape, making it difficult to distribute. There was a problem above.

To improve this point, at least the boundary between the edge frame and the bottom plate is configured at an acute angle, for example, in
As described in Japanese Patent No. 01, there is a case in which the edge frame and the bottom plate of the container component are constructed separately and bonded together during assembly.

However, even with such a structure, it is necessary to join the edges of the bottom plate with an adhesive after narrowing them down.

Originally, heat fusion is the most efficient way to bond synthetic resins together, but foamed resins have poor thermal conductivity, making it impossible to apply such a manufacturing method, resulting in poor impact resistance. There was a problem in that the joint surfaces were likely to separate and fail.

Furthermore, in order to use foamed resin for the bottom plate and to provide strength, it is necessary to increase the thickness, which has the disadvantage that the essential problem of the internal capacity being small compared to the external capacity cannot be solved.

The present invention solves the above-mentioned drawbacks and improves the structure by providing a groove on the periphery of the bottom plate into which the lower end of the edge frame is inserted and fitted, especially when the bottom plate is made of a thin and dense resin plate. This provides a relatively strong disposable food container.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described based on the attached drawings.

FIG. 1 shows the edge frame 2 of the container, which can be formed into any polygonal, circular, or circular shape using wood, cardboard, or synthetic resin material such as expanded polystyrene.

Figure 2 shows the thickness of synthetic resin materials such as impact-resistant polystyrene and polyvinyl chloride, which are 0.2 to 0.7 rIr! ! A bottom plate 3 made of a thin plate of t is shown.

A groove 5 is provided on the peripheral edge of the thin bottom plate 3, into which the lower end 4 of the edge frame 2 is inserted and fitted.

The bottom plate 3 has the function of providing strength against bending to the flexible bottom plate by the partition pro and the groove 5 on the periphery, and also has the function of providing strength to the entire container when the box body is formed.

FIG. 3 shows the lower end 4 of the edge frame 2 in FIG.
The food container 1 of the present invention is shown in a state in which the food container 1 of the present invention is formed by inserting and fitting into the peripheral groove 5 of the container.

4 and 5 show the state in which the groove 5 formed by the lower end 4 of the edge frame and the raised edge 7 of the bottom plate are inserted and fitted.

In the figure, 8 indicates an adhesive, but if the edge frame is made of a material that melts at a relatively low temperature, it can be fused by heating from the bottom plate.

As shown in the figure, the edge frame 2 and the thin bottom plate 3 are fitted with a relatively wide contact area and are also bonded together, so that the food container 1 can be formed into a strong food container 1 even though the thin bottom plate is used. , and can prevent liquid leakage due to food.

According to the present invention, since a thin synthetic resin plate is used as the bottom plate, it is easy to process, and the disposable food container has an internal volume that is almost the same as the external shape, is difficult to deform, and does not cause liquid leakage. can be obtained.
