Description

Detailed Description of the Invention <Industrial Application Field> The present invention is mainly used as a packaging container for distribution of chicken eggs, and the body part and the lid part are arranged at a plurality of opposing positions in a closed position. A container in which a recess with a small projection protruding from the forming wall for forming an egg storage space and a partition are respectively formed, and the body side and the lid side are on one side thereof. This invention relates to an egg container which is integrally formed in a series so as to be foldable.

<Prior art> This type of egg container conventionally uses a series of synthetic resin sheet materials, and molds the body part and the lid part side into one piece by means such as vacuum forming or pressure forming. All of them were single-piece containers.

To store eggs in such an egg container, put the lower half of the egg into the recess on the body side, fold the lid side from the connecting part and put it over it, and then connect the free end flange pieces of these two parts. is polymerized, and the polymerized flange pieces are stapled or welded to seal the entire container. Therefore,
There were no unexpected openings during the distribution stage.

<Problems to be Solved by the Invention> However, eggs are inherently extremely sensitive to impacts and break easily, and even if they are housed in a container as described above, they often break during the distribution stage. For example, if one of the 10 eggs in a 10-egg container breaks, the other 9 eggs in the container will break.
The current situation is that individual eggs no longer have any value as a product and cannot be sold as they are. In order to sell these eggs as a product, it would be a hassle to open the container, wipe the dirty eggs, and refill them with other normal eggs into a new container.

In addition to such damage during the distribution stage, damage often occurs even after purchase by end users, often resulting in complaints to retailers.

This is the current state of affairs even when eggs are sold through normal distribution channels, so mail order methods, which are considered to be a different method of selling eggs, are at least able to sell eggs in a single piece than the conventional method of selling eggs. It is impossible to use egg containers because the risk is too great, and currently there is no mail-order sale of eggs.

Therefore, the present applicant aims to solve these problems, and hereby proposes an egg container with excellent impact resistance that has been able to solve these problems. In addition, it can be used as an egg container without any problems with the conventional means of opening using cables, and furthermore, it can be used as an egg container without any problems with the conventional method of closing the lid by stapling or welding. without causing any hindrance, and
The object of the present invention is to provide an impact-resistant egg container in which conventional closing means (closing machine) can be used without the need for modification.
