BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container for dividing and assembling a plurality of foods and the like, which is convenient for servicing foods or carrying and is suitable for heat treatment in an oven. The present invention relates to an assorted container for foods and the like and an integrated paper board for forming the container.

[0003]

2. Description of the Related Art Conventionally, most materials for disposable assorted containers (tableware) used in the food industry are made of polystyrene, which is advantageous in manufacturing and cost, but the containers cannot withstand high temperatures. Moreover, since the container itself cannot be decomposed naturally, it is becoming a serious threat to human health and environmental protection.

Therefore, in recent years, paper tableware has been developed in place of polystyrene tableware, and polystyrene tableware is gradually being removed. However, at present, tableware such as a lunch box or a lunch plate can be produced by an extrusion molding method by folding them together using a paper board, but at present, a polystyrene-made fast food or Compared with tableware for light meals (containers that are integrally molded and that is a container for assembling tableware with slightly protruding divider plates), cutting, folding, and riveting paperboard (fixing multiple paperboards with ear nails) Is not perfect and it is hard to say that it is sufficient in container molding technology.

All the tableware or lunch plates that are commonly used at the present time are waterproof, and all the tableware made of polystyrene are foam-molded in a fixed mold. It is technically very difficult to apply and the cost is high. If a container is press-molded from a single paper board like a metal plate, the paperboard has almost no extensibility, and as a result of the press, the corners, curved parts and defective parts of the molded container are Irregular deformations and curves occur. For this reason, paper tableware is hygienic and has the advantage of not causing the problem of environmental pollution, but it is in a situation where it cannot compete with polystyrene tableware. Also, use an integrated paper board and fold it in order.
