Description

[Detailed explanation of the idea] The present invention relates to food containers.

Conventionally, a relatively thick frame is made of wood or plastic material, such as expanded polystyrene, and a transparent or translucent bottom plate made of polystyrene, high-impact polystyrene, polyethylene, polypropylene, vinyl chloride, etc. is attached to the bottom of the frame. Mounted food containers are already known.

These food containers with transparent or translucent bottom plates have a weak, uncomfortable, and cheap feeling because even when food is stored inside, the fingers of the hands supporting the container can be seen through the gaps between the food. Met.

In order to eliminate the transparency or translucency of such containers, it is necessary to mix pigments into the plastic material of the thin bottom plate in advance and mold the thin bottom plate, or to perform post-processing such as coloring the finished thin bottom plate by spraying or the like. This method has disadvantages such as increased manufacturing steps and high cost.

An object of the present invention is to improve the drawbacks of food containers having such transparent or translucent thin bottom plates.

The present invention comprises a floating frame 1 made of a plastic material such as foamed plastic or wood, a thin bottom plate 2 made of a transparent or translucent plastic material attached to the bottom peripheral edge circle or lower inner peripheral edge of the floating frame, and the thin bottom plate 2 made of a transparent or translucent plastic material. This food container is characterized by being made of paper material 3 attached below the bottom plate.

Next, the present invention will be explained in detail with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a floating frame, ie, a relatively thick frame, made of a plastic material such as expanded polystyrene or wood.

The floating frame 1 has a partitioning/reinforcing rib 4 on the bottom peripheral edge.
A thin bottom plate 2 made of a transparent or translucent plastic material such as polystyrene, high-impact polystyrene, polyethylene, polypropylene, vinyl chloride, etc. is fixed.

Furthermore, as seen in FIGS. 2 to 4, a paper material 3 is attached with adhesive under the thin bottom plate.

5 and 6 show another example of the present invention, in which a transparent or translucent thin bottom plate 2 is fixed to the lower inner peripheral edge of the floating frame 1 by, for example, adhesive.

Under the thin bottom plate above is a paper material 3 whose size is somewhat larger than that.
is attached to the bottom peripheral edge of the floating frame 1, for example, with adhesive.

The paper materials include those with various patterns on the surface, such as thick paper such as cardboard, plastic processed paper, composite synthetic paper, and other sheet materials with functions similar to paper, and composite paper with decorative paper pasted. It can be used and also
It is also possible to use a paper material 3 having a size larger than the area occupied by the bottom plate 2.

The present invention has a structure in which a paper material is further attached under the thin plastic bottom plate integrally molded with the partition, so that the following effects can be achieved.

(1) Since the bottom plate itself can be reinforced, there is no need to consider problems related to the strength of the bottom plate itself.

Conventionally, a thin dense plastic material was used as the bottom plate, and by combining this with a floating frame made of foamed plastic material, it became possible to heat and fuse the material, resulting in significant automation of the manufacturing process.

However, the ability to provide many partitions by integral molding on the bottom plate was limited due to its strength, but the reinforcing effect of paper material has made it possible to provide any number of partitions in any location, making it functional. This opens the door to automatically assembling enlarged food containers.

(2) The insulation, texture, and decorative functions of paper materials can be efficiently incorporated into disposable plastic containers.

When a thin plastic plate is used as the bottom plate, insulation properties,
There are problems such as translucency and discomfort due to the recessed part of the integrally molded partition, but all of these problems can be solved by providing paper material under the bottom plate.

(3) The container itself can be physically stabilized.

When a relatively thick paper material is used, the stability of the container can be increased, and the height of the container frame can be increased accordingly.

Furthermore, by using a paper material with a surface area larger than that of the bottom plate under the bottom plate, the stability of the container itself can be further increased, making it possible to manufacture a stable pot-shaped container.
