Therefore, the wrap film W remaining between the cover piece 15 and the front plate 18 after the cutting is completed is held by the adhesive tape 23 in the notch 18b, and the wrap film W is attached to the case body 11 after wrapping is completed. This prevents it from being rolled back inside.

In the second embodiment shown in FIG. 7, the cover piece 15 and the cutting member 21 attached thereto are made to protrude in a substantially trapezoidal shape at the center thereof. In this case, the method of cutting the wrap film W is the same as the embodiment shown in FIG.
By simply pulling the central portion of the film in the horizontal direction, the wrap film W is cut from the central portion by the saw blade 21a located at the trapezoidal protruding portion J, and is neatly cut. In addition, in this second embodiment, if a substantially arc-shaped notch 18c is provided in the front plate 18 of the case body 11, after cutting the wrap film W to a required length, the protrusion J can be inserted into the notch 18c. You will be able to insert it into the . This makes it possible to prevent the lid 14 from opening when not in use.

In the illustrated embodiments, the cutting member 2L has a substantially triangular or trapezoidal shape that deforms at an acute angle. It is also possible to make it into a protruding shape.

Furthermore, the edge of the central portion C shown in the embodiment shown in FIG. 2 or the protrusion J in the embodiment shown in FIG. It may be provided at a position that is biased towards the other side.

〔Effect of the invention〕

As described above, in the present invention, since the cutting blade provided at the edge of the cover piece has a protruding shape, the film surface is extremely lifted in order to apply a force in the right angle direction to the wrap film surface pulled out from the case body. Even if you don't have one, just by pulling the blade in a horizontal direction, the protruding part of the blade will first cut the center of the film, and the cuts will extend to both sides, making it possible to cut cleanly. This eliminates wrinkles in the cut film, and prevents the films from sticking to each other while being twisted.The cut wrap film becomes almost horizontal, and there is no need to spread it out with both hands. It becomes possible to cover the object to be packaged.
