Description of the Related Art A storage box of this type forms a box body with a front plate portion, a bottom plate portion, a rear plate portion, and a lid portion having an extending piece that overlaps the front surface of the front plate portion. A tin cutting blade with a serrated cutting edge is provided on the back surface of the tip of the extension piece in this box body, and the wrap film wound in a roll shape and stored in the box body is pulled out to the desired length and cut. It is designed to be cut with a blade.

のが望ましい。The high-adhesion surface B may be provided only on the end of the wrap film F on the cutting start side, but the box for drawing and cutting the film may be selected depending on whether the user is right-handed or left-handed. Since it may be in different directions, it is desirable to provide it at both ends.
【0032】また、この高密着面B,Bは、フィルムF

る。The portion other than the high adhesion surface B (low adhesion surface C) is the film F.
The film F does not adhere to this low adhesion surface C, and most of the film F adheres to the smooth layer 8. This smooth layer 8 is the high adhesion surface B of the cutting blade 7. By setting the adhesive force with the film F higher than that, it is possible to reliably prevent the phenomenon that the film F returns to the inside of the box while being stuck to the cutting blade 7 after cutting.

定すればよい。The adhesion of the high adhesion surface B to the film F is within a range in which slippage with the film F can be prevented, and the rebound phenomenon of the film F does not occur, that is, the thumb is released from the extension piece 6 after cutting. At this time, the wrapping film F has a size such that the high adhesion surface B naturally separates from the film F due to the restoring force of the extending piece 6 in the direction away from the front plate portion 2, and such adhesion is obtained. The smoothness and area of the high adhesion surface B may be selected according to the material (degree of self-adhesion).
