Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wrap film storage case for storing a roll of wrap film (hereinafter referred to as "wrap film roll") used for storage of foods.

[0002]

2. Description of the Related Art Conventionally, a wrap film storage case of this type is made of a paper container, and a wrap film roll is stored in the container, and a wrap film is pulled out from the stored wrap film roll to a predetermined size. A metal cutter is caulked and fixed to the lid of the container so that the container can be cut in length.

However, according to the conventional wrap film storage case as described above, since the cutter is caulked and fixed to the lid of the container, the cutter can be easily operated even if the cutting performance (cutting performance) of the cutter is deteriorated. It is not easy to use because the wrap film cannot be replaced and the wrap film must be forcibly cut with a cutter with poor sharpness.

Further, in the above conventional wrap film storage case, when all the wrap film stored in the container is used up, a part of the conventional wrap film storage case is not recycled, The reality is that everything is discarded as garbage. This is because, for example, in a conventional wrap film storage case, if the paper container is to be recycled as recycled paper, it takes time to remove the metal cutter that is caulked and fixed to the lid of the container, and the recycling is required. It is thought that this is because the cost becomes high.
