However, no matter what form these fruit packaging containers are, they are now widely used in the distribution stage as bar code product automatic reading means. It is unrelated.

This is because the commodity price of fruits and the like that are packaged using this type of fruit packaging container is a commodity that is sold at a low price because it is a daily food, so the price of the container itself is low. Is required, and the cost required for packaging is required to be reduced. In addition, when disposing of the container, a PVC system that generates toxic gas when burning and toxic chlorine etc. flows out when dumped underground Cheap materials are used,
It is rarely recycled, and the same is true when other materials are used, which leads to waste of resources.

In addition, since the conventional fruit packaging container of this kind has nothing to do with the means for automatically reading the commodity by the bar code, after storing the fruit in the container,
It has a problem that it has the complexity of having to manually attach a barcode or the like to a thin-film external packaging body that has wrapped the entire container, which is also a cause of increasing the cost of the product. It was

Therefore, the present inventor aims to solve such a problem, avoids the complexity of manually attaching a bar code or the like, and can eliminate the cause of the high cost of the product. This is a fruit container that enables the effective recycling of post-containers and the effective use of resources without the risk of causing harmful gas or chlorine outflow to humans and animals even when disposed of.
