Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to wrap films (polyvinylidene chloride-based, polyvinyl chloride-based, polyethylene-based, polybutanediene-based, etc., synthetic resin films, metal foils such as aluminum foil, glassing paper, wax. Long papers such as paper and laminated products of these, which are collectively referred to as those that are used by pulling out wound ones) are stored, and are related to a wrap film storage case in which each used amount is pulled out and cut, A wrapping film storage case capable of safely and very easily peeling a cutter member attached to a paperboard box body from the paperboard box body when the case is discarded after all use of the film Is.

[0002]

2. Description of the Related Art As shown in FIG. 3, a conventional type is a paperboard box 1 containing a synthetic resin film or a wrap film such as an aluminum foil, and is made of a metal for cutting the film drawn by the amount of use. In the wrap film storage case having the structure in which the cutter member 2 is attached, the metal cutter member 2 can be safely and easily removed from the paperboard box body 1 particularly when the case is discarded after the film is completely used. In the case where the cutter member 2 provided with the caulking projections 13 is attached to the cover lid piece 9 in the illustrated example at an appropriate portion of the paperboard box body 1 by caulking the caulking projections 13, The cutter member 2 separates the caulking protrusion 13 at the caulking fixing portion from the paperboard to the cover lid piece 9 which is caulked and fixed by the caulking protrusion 13. A cut 16 is provided, and when an external force for removal is applied to the cutter member 2, the caulking state is weakened along the cut 16 and the cutter member 2 is removed from the paperboard box body 1. .

[0003]

The performance of removing the cutter member 2 of the conventional construction from the paperboard box body 1 is as follows.
When the cutter member 2 is attached to the tip edge portion of the covering lid piece 9 or the upper edge portion of the front surface 3, it is significantly lower than when it is attached near the ridgeline between the front surface 3 and the bottom surface 4.
The cause is that the surface of the portion where the cutter member 2 is attached in the vicinity of the ridgeline between the front surface 3 and the bottom surface 4 is stable due to the ridgeline, and therefore an external force for removal is applied to the cutter member 2. At this time, the cut line 16 works effectively. On the other hand, when it is attached to the tip edge of the cover lid piece 9 or the upper edge of the front surface 3, the surface of the portion to which the cutter member 2 is attached is unstable because it is along the cutting line. When an external force for removal is applied to
The surface of the part where the cutter member 2 is attached is pulled apart,
It is difficult for the cuts 16 to act effectively, and extra force is required to separate the crimping projections 13.

Therefore, the paperboard box 1 of the product is covered with the metal cutter member 2 and the synthetic resin film G, which has a length such that both ends can be pinched with fingertips, is laid on the back surface of the metal cutter member 2 to form a cover. It is attached to the tip edge of the piece 9 to provide an appropriate picking portion so that pulling force can be easily applied, and slippage of the caulking projection 13 is assisted by sliding of the synthetic resin film G. While this contributes to environmental problems by separating waste, it also causes environmental problems.

The present invention solves the above problems of the conventional wrap film storage case described above,
An object of the present invention is to provide a wrap film storage case in which a cutter member attached to a paperboard box can be safely and very easily peeled off when the case is discarded after use.

[0006]

In order to achieve this object, the present invention has the following configuration. That is, a front surface, a bottom surface, a back surface, both side surfaces, a lid surface, and a cover lid piece extending in a direction covering the front surface from the lid surface as a main portion, and a cutter member by a caulking projection at an appropriate portion of the main portion. A fixed rectangular parallelepiped board box body, in a wrap film storage case capable of pulling out and cutting a necessary amount of wrap film stored inside, the cutter member being caulked by the caulking projections. Half-cuts are provided on the front surface and the back surface of the paperboard so as to peel off the paperboard around the cut portion so that the area on the side where the cutter member is fixed is widened.

[0007]

According to the present invention, since the above-mentioned means is provided, the skirt portion formed by the half cuts provided on the front and back sides of the paperboard around the portion where the cutter member is caulked by the caulking projection is the cutter member. In the state of being attached by caulking, it is backed up by a rigid cutter member and securely bonded. On the other hand, when an external force for peeling is applied to the cutter member, the jumper portion is peeled off with an extremely weak force.
