Grindstone particles are stuck to the folded lines (a) of the front cover backing plate 70 or the lowerend part including the lowerend side, through an adhesive to form a grindstone blade 10.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wrap film containing paper box with a grindstone blade, which is excellent in cutting performance and cutting durability, such as household aluminum foil and resin film.

[0002]

2. Description of the Related Art Conventionally, a household provided with a metal saw blade, which is used by pulling out one end of a wrap film such as a rolled aluminum foil or a resin film housed in a paper box and cutting it to a required length A wrap film containing paper box is widely used.

Further, conventionally, instead of a metal saw blade of a paper box containing a wrap film for household use, a curable resin as shown, for example, in Japanese Utility Model Publication No. 47-34588 (Cutting tool for household aluminum foil feeding container). The invention of a wrap film containing paper box provided with a paper saw blade coated and hardened with, for example, or through an adhesive as shown in JP-A-57-183946 (paper box with film cutting means). Many inventions of a wrap film containing paper box provided with a paper saw blade to which hard powder is attached have been disclosed.

[0004]

In connection with the recent problem of waste disposal related to the global environment, a household wrap film provided with a metal saw blade because it has a metal saw blade. There is a problem in the incineration of used paper boxes as waste after use and the recycling of paper as raw materials for papermaking, so there is a need for household wrap film storage paper boxes equipped with paper saw blades instead of metal saw blades. The demand is increasing.

In addition, the above-mentioned household saw blade provided with a hard sawing blade coated with a curable resin or the like and hardened with an adhesive agent is used. Although it is easy to incinerate the wrap film-containing paper box as waste after use and to recycle it as a raw material for papermaking, there are problems with the cutting performance and cutting durability of the paper saw blade. In particular, regarding a wrap film containing paper box provided with a paper saw blade to which hard powder is adhered via an adhesive as described in JP-A-57-183946, the wrap film containing paper box is exposed on the outer surface side of the wrap film containing paper box. The paper saw blade that is used is subject to external forces such as friction before and during use, and hard powder that has adhered to the tip of the paper saw blade easily separates. There was a problem that the cutting performance deteriorates.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems of a household wrap film containing paper box, the present invention, as shown in FIG. 1, has fold lines (dotted lines without reference numerals, The same shall apply hereinafter) through the front plate (20) and the bottom plate (3
0), the rear plate (40), the upper cover plate (50), and the front cover plate (60) in this order, and the side plates (31, 31) on the left and right sides of the lower bottom plate (30), respectively. The front side plate (20) and the rear side plate (40) to the left and right of the adhesive strip (21,
41,21,41) in a horizontally long rectangular parallelepiped wrap film containing paper box, the front lid backing plate (70) of a horizontally long rectangle through the fold line (a) on the lower end side of the front lid plate (60). By connecting them,
This front lid backing plate (70) is provided with a whetstone grain blade (10) having grindstone grains adhered through an adhesive at the lower end (upper end in FIG. 1) including the fold line (a). The present invention provides a wrap film containing paper box with a grindstone blade, which is excellent in cutting performance and cutting durability.

Further, as shown in FIG. 3, the present invention provides a front plate in a paper box containing a horizontally long rectangular parallelepiped wrap film.
A horizontally long rectangular front lid backing plate (70) is connected to the upper end side of (20) through a cut line (e), and the lower end portion including the lower end side of this front lid backing plate (70) (see FIG. At the upper end), a whetstone grain blade (10) having whetstone grains attached via an adhesive is provided, similar to the above, the whetstone grain blade having excellent cutting performance and cutting durability. The present invention provides a paper box containing a wrap film.

[0008]

In the wrap film containing paper box with a grindstone blade of the present invention, a fold line (a) or a cut line (e) is provided on the lower end side of the front cover plate (60) or the upper end side of the front plate (20). By horizontally connecting the oblong rectangular front lid back plate (70), by bonding the back surface of the front lid plate (60) and the back surface of the front lid back plate (70) as shown in the example, Also, as shown in the examples, a strong adhesive used in the production of ordinary sandpaper is applied to the lower end portion including the fold line (a) or the lower end side of the front lid backing plate (70), and Grindstone blade (10) is provided by sprinkling gold sand (grindstone) for sandpaper and fixing it to provide a grindstone blade (10).
As shown in FIG. 5 (A) or FIG. 5 (B), the wrap film containing paper box with a whetstone grain blade is opened to form a roll-shaped wrap. When one end of the film (80) is pulled out by the required length and the front cover plate (60) is lightly pressed with fingers to cut, especially the crease line (a) or the lower end side of the front cover back plate (70) is cut. Since the grindstone blade (10) sharply scratches the wrap film (80), excellent cutting performance of the grindstone blade (10) can be obtained.

Further, in the wrap film accommodating paper box with a grindstone blade according to the present invention, the front lid backing plate (70) has a fold line (a) or a lower end portion including a lower end side as shown in FIG. As shown in (B), by providing a flat grindstone blade (10) with a non-serrated blade edge so as not to be exposed on the outer surface side of the wrap film containing paper box, friction such as before or during use It is hard to be affected by external force, and a strong adhesive used in the production of ordinary sandpaper is applied, and since the hard sand (grinding stone) fixed by sprinkling does not separate, the grinding stone blade (10)
The excellent cutting durability of is obtained.
