Description

  The present invention relates to a wrap film roll storage box. Specifically, the present invention relates to a container for storing a roll of wrap film used for packaging of food or the like, and relates to a wrap film roll storage box that can be used repeatedly by refilling the wrap film scroll.

  Conventionally, this type of wrap film storage box is made of a paper container, and the wrap film roll is stored in the container, and the wrap film is drawn out from the stored wrap film roll to a predetermined length. In order to be able to cut, a metal cutting blade is caulked and fixed to the lid of the container. However, according to the conventional wrap film storage box as described above, since the cutting blade is caulked and fixed to the lid of the container, the cutting blade can be easily replaced even if the cutting performance of the cutting blade is reduced. However, there is a disadvantage that it is not easy to use, such as having to continue to use a cutting blade with reduced cutting ability.

  In addition, in the above conventional wrap film storage box, when all of the wrap film stored in the container has been used up, the storage box is not recycled even if only a part of it is discarded as garbage. It is the actual situation. For example, in a conventional wrap film storage box, when the paper container is recycled as recycled paper, it takes time to remove the metal cutting blade that is caulked and fixed to the lid of the container. The cost will be high. There was also a risk of cutting the fingers.

In order to solve such problems, there has been a proposal for a wrapping film storage box for refilling that can be used semi-permanently after all the wrap film has been used, and that can replace a cutting blade whose cutting ability has deteriorated. ing. For example, JP-A-2003-81280 (see Patent Document 1) and the like can be mentioned.
JP-A-2003-81280 discloses an upper opening-type container body that houses a wrap film roll, a lid that can be opened and closed at the upper surface opening of the container body, and a wrap film drawn from the wrap film roll. A wrap film storage case having a cutter to be cut is described (claim 1).

  As for the attachment structure of the cutter, it is only described that only one blade part 3b of the cutter 3 protrudes from one side edge of the pedestal plate 4 and can be cut. (See paragraph [0018]). However, FIG. 1 describes a form in which the lid is closed with a sharp blade edge 3b at the top when the lid is closed after the wrap film roll is refilled. Further, FIG. 5 describes a state in which it is stored, and it is described that the sharp blade edge 3b is stored in a form that is always exposed. Thus, it is difficult to say that the sharp cutting edge 3b is always exposed in terms of workability and safety at the time of refilling and storing the wrap film roll.
