Description

Corrugated Paperboard Receptacle for Packing Food}

The present invention relates to a food packaging container, and more particularly, by producing a corrugated cardboard of the box and the package support installed therein, it is possible not only to keep food in a fresh state for a long time. The present invention relates to a food packaging container using a corrugated cardboard that effectively prevents damage from being damaged by an impact from the outside by blocking the received food from being stored outside and wrapped by the packaging container.

In general, a synthetic resin container has been used for packaging and selling eggs, and such a synthetic resin container was manufactured by thinly forming a synthetic resin of transparent or translucent material. The egg packaging container is connected so that the upper and lower plates protruding a plurality of storage spaces so that a predetermined number of eggs can be stored can be rotated around the one corner portion, the storage space is in close contact with the egg surface The egg was configured in the same shape as the egg so as to prevent the flow of the egg.

However, such a conventional egg packaging container is made of a thin synthetic resin or paper molding both of the upper and lower plates, when made of a thin synthetic resin plate is to be in close contact with the surface of the egg, its supporting force and shock absorbing power is weak so that the external impact inside It is delivered directly to the housed eggs, which causes a problem of causing a large amount of damage and economic waste through the distribution process of several stages.

Also, even in the case of a packaging container made of paper molding, since the packaging container is manufactured using recycled paper, the toxicity of the neutralizing material used to neutralize components such as printing ink remaining in the waste paper remains in the container. If the food is stored, such as eggs can not maintain the freshness for a long time, as a result of the unsanitary consumer to eat the food infiltrated with harmful substances, with the top portion of the packaging material exposed As a result of the storage, there was a large amount of broken or contaminated lungs during transportation.

In order to replace such damaged eggs with new ones, the supplier and the seller had to take a lot of trouble, and when the consumers inadvertently bought the damaged eggs, they had to go to the place of purchase and exchange them for new ones.

In addition, such a conventional egg packaging container because it was formed of a transparent synthetic resin material was causing a lot of problems in the processing process after use. In other words, synthetic resins do not decay and decompose in their natural state due to the nature of the material, and when incinerated, they emit toxic gases, thus acting as pollutants that cause environmental pollution. In order to prevent this, the egg container must be separately collected and specially treated so that no toxic gas is released into the atmosphere. Therefore, the treatment process is very complicated and the treatment cost is also required.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and its main object is to provide a packaging material capable of more safely and hygienic packaging of food to be packaged.

Another object of the present invention is to provide a packaging material having a protective outer body such that an impact is not applied to a product even when the packaged food is mixed with other products and transported.

Still another object of the present invention is to provide a packaging material useful for informing a consumer of product characteristics and grades while ensuring a wider advertising area on the exterior surface.

Still another object of the present invention is to provide a packaging material that can be easily molded through a single press process and can be easily combined through an assembly process that folds sequentially along a fold line.
