Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cat sharpener using a polishing body formed by stacking corrugated cardboard sheets.

[0002]

2. Description of the Related Art Conventionally, as a cat's nail sharpener, there is one as shown in FIGS. This conventional nail sharpener Z
Is composed of a polishing body 2 made of corrugated cardboard and a storage box 10 for storing the polishing body 2. As shown in FIG. 7, the nail sharpener Z accommodates the polishing body 2 in the storage box 10 and uses the polishing body 2 for sharpening the nails of a cat. Incidentally, the polishing body 2
Both the front and back sides can be used as the nail sharpening surfaces 4 and 4, and when the nail sharpening surface 4 on the front surface side is completely used, the polishing body 2 can be turned over and used.

By the way, the corrugated cardboard-made polishing body 2 is formed by stacking a large number of corrugated paper sheets in a vertical orientation to form a thick plate having a predetermined area. In No. 2, as shown in FIG. 7, a large number of small holes 5, 5 ... Composed of corrugated folds of corrugated cardboard penetrate vertically. When the cat scratches the surface (nail sharpening surface 4) with the nail in the corrugated paper abrasive body 2, scraps of corrugated paper (hereinafter, this scrap is referred to as paper dust) are generated from the nail sharpening surface 4. The paper dust falls through the small holes 5, 5, ... To the lower surface of the polishing body 2.

As described above, in the nail sharpener using the corrugated board abrasive body 2, the paper dust generated from the nail sharpening surface 4 drops through the small holes 5, 5, ... To the lower surface of the abrasive body. Since the floor surface of the installation location of the nail sharpener is contaminated with paper dust if it is left as it is, the polishing body 2 is conventionally used by being put in the storage box 10. The storage box 10 may be made of plastic and can be used repeatedly (only the polishing body 2 is replaced), or a paper box used as a packaging material for the polishing body 2 that is disposable together with the polishing body 2.

[0005]

However, as shown in FIGS.
In the conventional nail sharpener shown in FIG. 2, paper dust generated from the surface (nail sharpening surface 4) of the polishing body 2 as described above falls through the small holes 5, 5 ... of the polishing body 2 to the lower surface of the polishing body. Therefore, in order to prevent the floor surface from being soiled with paper dust, it is necessary to use the polishing body 2 in the storage box 10 in a state of being stored.

In this case, although the plastic storage box 10 can be used repeatedly, there is a problem that the initial purchase cost is high, and when the polishing body 2 alone is purchased next time, it is used before. It is troublesome to find one that fits the size of the storage box 10 (the size of the polishing abrasive 2 for replacement is often different depending on the manufacturer), and sometimes the size of the storage box 10 does not fit due to misunderstanding. I sometimes bought my body (in which case it would be troublesome to bring it to the store for exchange).

Further, in the case where a paper box for packaging is used as the storage box, the storage box is sold together with the polishing body 2 so that it is convenient for purchase and use, but it is necessary to make the packaging material function as the storage box. However, there is a problem that the structure of the packaging material becomes complicated and the cost of the entire nail sharpener increases.

In view of the above problems, it is an object of the present invention to make it possible to omit a storage box for receiving paper dust in a cat sharpener using a corrugated board polishing body. Is.

The present invention has the following constitution as means for solving the above problems. still,
Each invention of the present application is directed to a cat nail sharpener using an abrasive body made of corrugated cardboard. The invention according to claim 1 of the present invention is a cat nail sharpener according to the invention according to claim 1 in which two corrugated papers are stacked in a vertical orientation and have two small holes vertically penetrating therethrough; A partitioning material having the same area as the polishing body is used, and the polishing body and the partitioning material are integrated with each other in a state where the small hole forming end faces of the polishing body are bonded to the front and back surfaces of the partitioning material.

Each of the two polishing bodies is formed with a large number of small holes vertically extending by corrugated material of corrugated paper.

As the polishing body, generally, a rectangular one in a plan view is often used, but in the nail sharpener of the present invention, a circular one or another shape other than the rectangle in a plan view can be adopted.
The thickness of this type of nail sharpener is generally about 30 to 40 mm, but in the present application, the thickness of each polishing body is 15 to 20 mm because of the connection of two polishing bodies. It is set to a degree. The thickness of each polishing body is not particularly limited, and the design can be changed appropriately.

As the partition material, an ultra-thin sheet such as a plastic film or paper, or a thin plate material such as a cardboard can be used. This partition material has the same shape as the planar shape of the polishing body and the same area size.

The two polishing bodies are integrated in a state of being bonded to the front and back surfaces of the partition material. In the nail sharpener according to the present invention, each polishing body is attached to the front and back surfaces of the partition material. They can be integrated by bonding them to each other with an adhesive.

Place one of them on the floor directly with the sharpening surface facing up. Then, when the cat scratches the upper surface side of the nail sharpener with the nail, paper dust is generated from the nail sharpening surface,
The majority of the paper dust falls into each small hole of the upper polishing body. By the way, in the nail sharpener according to claim 1, since the partition member is interposed between the upper and lower polishing bodies,
Each small hole of the upper and lower polishing bodies is blocked by a partitioning material, and even if the paper dust generated on the upper surface of the sharpening surface falls into the small holes of the upper polishing body, the paper dust is received by the partitioning material. Does not enter into the small holes of the lower polishing body. Therefore, even if the paper dust generated from the nail sharpening surface falls into the small hole of the upper polishing body, the paper dust does not reach the lower surface side of the nail sharpener and the floor surface is not contaminated with the paper dust.

Further, if the nail polishing surface on the upper surface side is clogged,
You can use the back (unused) nail sharpening surface,
At that time, flip the used surface of the nail sharpener on a rug such as newspaper (or outdoors) and tap it gently several times from the top,
After removing the paper dust adhering to the nail sharpening surface and the paper dust entering the small holes, the unused sharpening surface may be used upward. In addition, this nail sharpener for cats can be disposed of as combustible waste as it is after use of both the front and back nail sharpening surfaces. Invention of Claim 2 The invention of Claim 2 of the present application is the cat nail sharpener according to Claim 1 described above, in which the outer peripheral edge of each nail sharpening surface of each polishing body has a predetermined small height from each nail sharpening surface. An annular guard wall protruding outward in the thickness direction of the polishing body is provided.

The height of protrusion of each guard wall may be, for example, about 5 to 10 mm from the ground surface of the nail. Further, the upper and lower guard walls may be formed of a single strip-shaped body surrounding the outer side surface of the main body of the nail sharpener, but they may be attached individually to the upper and lower sides (divided into two). In addition, this guard wall is
It can be adhered to the outer peripheral surface of the nail sharpener body with an adhesive.

In this type of nail sharpening device, when a cat scratches the nail sharpening surface with a nail, a part of the scraped paper powder may be scattered outside the nail sharpening surface. If a guard wall is provided on the outer peripheral edge of the nail sharpening surface as described above, paper dust generated from the nail sharpening surface on the guard wall will not be scattered even in a nail sharpener that does not use a storage box. Can defend.
