CONSTITUTION:Latex of polyvinylidene chloride type, mixed with fine alundum powder is atomized on a front side, so that a sparse layer 9 of grinding particles in which small amount of grinding particles are mixed with resin is provided. A part of a sparse grinding particle layer 9 leaches the upper end of the front side. After being dried, pieces of file sheet 7 are applied to both edges of the upper end of the front side 2, a paper box is formed with a roll of aluminum foil inserted, and the box is sealed. When using this box, by rubbing aluminum foil 1 after pulling it out from an opening, with a piece of file sheet applied on the upper end of the front side while slightly extending it, the edge of the foil is torn first and this tear is induced along the cut edge of a sheet of paper at the upper end of the front side.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a dispensing container for wound film using a file-like rough surface as a cutting means.

[Conventional technology]

Conventionally, a dispensing container made of a film such as a rolled aluminum foil or a plastic film has been equipped with a sawtooth-cut metal plate as a cutting means with its tip protruding from the upper back surface of the front side surface. In this position, the cut film is stored in a paper box, which is sanitary, and the cutting means itself is also stored in the box, so it has the advantage of being easy to handle during distribution.

In this method, when pulling out the edge of the film, the fingers come into contact with the serrations, causing pain and discomfort, so a method of using a file-like rough surface as a cutting means was considered. In order to use the file-like rough surface as a cutting means, the abrasive grains must not fall off. Providing the abrasive sheet over the edge or across the cut edge of the paper requires special care to be made to prevent the abrasive grains from falling off even when the file sheet piece is folded, and this tends to be expensive. Therefore, it is preferable to attach the file-like rough surface to the upper end of the front side surface. The edge is the starting point for cutting the film, and once cutting is initiated, a tear is induced along the cut edge of the paper at right angles to the length direction.

[Problem to be solved by the invention]

However, since the wrapped film container's primary use is for cooking, it must be expected to be handled with wet hands. There is no problem because the paper is coated with resin to make it water resistant, but the paper material is exposed at the cut edges. When this exposed part gets wet with water, the paper loses its tension, a so-called sagging state, and loses its ability to guide the film perpendicular to its length after it has been cut by the file-like rough surface.

Therefore, there has been a need for a simple method for imparting water resistance to the cut end of the upper front side of a paper box.

[Means to solve the problem]

The present invention is aimed at solving the above problems, and is composed of a paper box that stores a wound film and unrolls it from the end. It has a shape in which an opening is formed at the top, an upper side extends from the free end of the rear side, and a cover piece extends from the free end of the upper side. A file-like sheet piece to which abrasive grains are fixed is attached to the upper end in contact with the opening, and the upper part of the front side surface is covered with resin or resin mixed with abrasive grains. .

Films include aluminum foil, glassine paper, wax paper,
It is a plastic film such as polyvinylidene chloride film, and is wound around a paper tube and rotatably stored in a paper box. In the case of aluminum foil, it is pure aluminum with a thickness of about 10 to 30 microns.

The paper box is preferably a rectangular box in which a film wound around a paper tube can be rotatably laid down and stored. That is, it consists of a rectangular front side, a bottom side, a rear side, and two square side pieces, with a rectangular opening formed at the top, and a rectangular upper side extending from the free end of the rear side. It has a shape in which a cover piece extends from the free end of the side surface. Attach sanding sheet pieces to both ends of the upper end of the front side of this paper box.

The file seal l-piece is made by firmly adhering abrasive grains to a base material such as paper, cloth, or plastic sheet so that the abrasive grains do not fall off even when folded.

For example, a thermosetting adhesive is used to fix the abrasive grains in a single layer to the base material so that about 2/3 of the abrasive grains are buried, and a rubber-based adhesive with a high modulus is used to increase the bending strength. There are methods such as coating the grain layer.

It is important to ensure that abrasive grains are present at the upper end of the front side of the paper box, preferably at both ends, in order to improve cutting efficiency. It is preferable to bend and cover the end of the

The file-like rough surface is one in which a material harder than the above-mentioned film forms an uneven surface having microscopically sharp corners, and is preferably made of alundum, corundum, or the like. However, any file that does not belong to the concept of a normal file is also included as long as it has the effect of initiating cutting on the film.

A resin layer or a resin layer mixed with abrasive grains is applied to the cut end of the paper at the upper end of the front side of the paper box to impart water resistance. Since the cut edge of the paper has a narrow width that matches the thickness of the paper, as shown in Figure 2, the paper box-forming paper that has been cut after printing and resin coating is overlapped, and the cut edge at the upper edge of the front side is stacked. By applying a resin emulsion or resin solution to the cut end, the cut end can be coated and protected at once. Furthermore, if fine abrasive grains are mixed into the resin emulsion or resin solution, a better tear-inducing effect can be obtained.

[Effect]

The present invention is a rolled film dispensing container, in which a file sheet piece is pasted to the upper end of the front side, the film is started to be cut with this file-like rough surface, and the cut end of the paper is used as a guide. The guide is perpendicular to the length direction. Since the parts of the paper that are still cut are not coated with resin, they are susceptible to getting wet, causing the paper to swell and lose its cutting-guiding effect. In the present invention, the cut edge of the paper at the upper end of the front side is also coated with resin to prevent swelling due to wetness and to prevent deterioration of sharpness due to repeated use.

〔Example〕

FIG. 1 is a perspective view of a dispensing container using aluminum foil as the film. [Aluminum foil wrapped around a paper tube] is the front side 2
, is housed in an oblong container consisting of a bottom side 3, a rear side (not visible in the drawing), and two square side pieces 6. An upper surface 4 extends from the free end of the rear surface, and a cover piece 5 extends from the free end of the upper surface 4. Reference numeral 7 denotes a piece of file sheet placed over the cut ends 8 of the paper at both upper ends of the front side surface 2, and is the cutting means in the present invention.

The printed and resin-coated paper was cut into containers and stacked as shown in FIG. 8 is a surface where the upper ends of the front side surfaces are overlapped. A polyvinylidene chloride resin latex mixed with fine alundum powder was sprayed onto this surface 8 to provide a sparse abrasive layer 9 in which a small amount of fine abrasive grains were mixed into the resin. A portion of the sparse abrasive grain layer 9 leaked out to the upper end of the front side. After drying, sanding sheet pieces were attached to both ends of the upper end of the front side surface 2, and a paper box was formed and sealed while inserting rolled aluminum foil.

In use, after pulling out the aluminum foil I from the opening, by pulling it slightly and rubbing it against the piece of file sheet I attached to the upper end of the front side surface 2, the edge will be torn first, and this tear will be removed from the front. Guided along the cut edge of the paper at the top edge of the side. In this example, the thickness is 20μ, the width is 15cm, ]
Hold the container containing the Om roll of aluminum foil with wet hands, and
It was unrolled and cut into various lengths from cm to 30 cm every 5 minutes, and was repeated 63 times in total until it was completely unrolled, but no sagging of the upper end of the front side was observed. On the other hand, in the case where the upper end of the front side surface was not coated with resin, the paper deteriorated after about 15 cycles, and the cutting guiding effect was lost.
