Description

[0001]
BACKGROUND OF THE INVENTION
The present invention accommodates a roll-shaped packaging material supplied in a rolled state such as a wrap film, aluminum foil, cooking paper, and a metal saw blade for cutting this into a required length. The present invention relates to a roll-shaped packaging material storage carton.
[0002]
[Prior art]
In recent years, separation and disposal of trash has been widespread, and as part of this, it is desired that a used roll-shaped packaging material storage carton is separated and discarded by removing a metal saw blade from a cardboard carton body. In this case, the metal saw blade is firmly fixed by inserting and bending a cross-shaped or horizontal H-shaped fixed portion into the carton body, and the saw blade protrudes from the edge of the carton body. However, there is a problem that it is difficult to remove and difficult to separate because it cannot be grasped. Even if some kind of tearing method is used to tear the carton along the saw blade near the saw blade, there is a risk of hurting the hand and pulling the saw blade directly. As a means to solve this problem, a tin plate laminated with a film protruding from both ends is fixed to the carton body as a saw blade, and when discarding, the film is pulled from the carton body without directly touching the metal saw blade. A method of sorting is known.
[0003]
However, since the metal saw blade is firmly fixed to the carton body as described above, the method of pulling the saw blade directly or indirectly causes the blade to be bent near the caulking and wound into a spring shape. Therefore, when it is separated from the carton body, it may hit the hand and cause injury, which is not a sufficient shape from the viewpoint of safety. As a method for solving this problem, the present inventor applied the cut tape along with the saw blade without directly grasping the saw blade in the separation process, and cut the cut tape on at least one side of the cut tape. Has proposed a roll-shaped packaging material storage carton characterized by forming a trigger portion for pulling (see, for example, Patent Document 1).
