Abstract

PROBLEM TO BE SOLVED: To solve the problem of the prior art that the tip side is the first portion to be damaged in a brush of this type, and under the existing circumstances, even if the base end side is little damaged, the brush becomes inconvenient to use, and it is discarded, resulting in exerting an undesirable influence on the environment because most of the bushes are formed of synthetic resins, and on the other hand, in the case where the brush part is replaceable, complicated machining is required for an attach and detach means, resulting in that the bush itself costs high. SOLUTION: In a brush formed by a brush base implanted with a number of bristles at the tip side, and a grip part extended from the brush base, a number of bristles implanted in the brush base are divided into plural blocks in the cross direction, and a fragile part which can be cut is provided between the blocks.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a brush which can be gripped and used by hand, such as a toothbrush, a clothes brush, a shoe brush, and a polishing brush for parts and the like. The present invention relates to a brush which can be used as a new brush by cutting and removing the tip of the brush which is damaged first.

[0002]

2. Description of the Related Art Conventionally, there are many types of brushes that are held and used by hand, such as toothbrushes, and if a brush is damaged when used, it is discarded as it is. There has also been developed one in which the brush base on which the bundle is implanted is made detachable and only the brush portion is replaced.

[0003]

However, most of the brushes of this kind are damaged first on the distal side, and even if there is almost no damage on the proximal side, the usability is deteriorated. Many of them are made of synthetic resin, which has an adverse effect on the environment, and replacement of the brush part requires complicated processing for attaching and detaching means, and the cost of the brush itself is high.

[0004]

DISCLOSURE OF THE INVENTION In view of the above-mentioned problems, the present invention has been intensively studied, and as a result, a brush base having a large number of bristle bundles implanted on the distal end side thereof, and a grip portion extending from the brush base. In this brush, a large number of bristle bundles implanted on a brush base are divided into a plurality of blocks in the width direction, and a fragile portion that can be cut is provided between each block.

Therefore, an object of the present invention is to cut and remove the hair bundle at the tip side which is first damaged together with the block,
An object of the present invention is to provide a tip-cut brush in which a block of a bristle bundle on the proximal end side with less damage can be used as a tip, and a single brush can be repeatedly used.

[0006]

According to the tip cutting brush of the present invention, a large number of bristle bundles planted on the brush base are divided into a plurality of blocks, and a fragile portion which can be cut is provided between the blocks, thereby reducing damage. The hair bundle on the violent tip side is removed, and the hair bundle on the proximal side with less damage is used as the tip.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a brush according to an embodiment of the present invention;

FIG. 1 is a schematic perspective view of an embodiment of a tip cut brush of the present invention, FIG. 2 is a perspective view of an embodiment of the tip cut brush of the present invention when cut, and FIG. FIG. 4 is a perspective view in which a cap is attached to a cutting portion of the embodiment of the tip cut brush, and FIG. 4 is a perspective view of a state in which the jig of the embodiment of the tip cut brush of the present invention is used for cutting.

The present invention is particularly directed to toothbrushes, clothes brushes,
The present invention relates to a brush that can be gripped and used by hand, such as a brush for polishing shoe brushes and parts, and more specifically, cuts and removes the tip of a brush that is damaged first by use and constantly uses it as new. The present invention relates to a brush that can be formed by a brush base 2 having a large number of bristle bundles 1 implanted on the distal end side, and a grip portion 3 extending from the brush base 2. A large number of implanted hair bundles 1 are divided into a plurality of blocks in the width direction, and a fragile portion 4 that can be cut is provided between each block.

That is, the bristle bundle 1 of the tip cut brush of the present invention.
Is a bundle of a plurality of natural fibers such as animal plants, artificial fibers made of synthetic resin such as nylon, metal wires, and the like, depending on the purpose of use.

The brush base 2 has a number of small holes formed therein for implanting the bristle bundles 1, and the bristle bundles 1 are implanted in each of the small holes. Things.

Further, the grip portion 3 extends from the brush base 2, and has a rod-like shape having an appropriate length so as to be gripped by hand and facilitate use of the brush. Things.

Next, as shown in FIG. 1, the tip cutting brush according to the present invention provides a brush base 2 with a large number of small holes to partition a large number of bristle bundles 1 which are individually planted in appropriate width directions. It is divided into blocks, usually one that is severely damaged,
It is preferable that about two rows constitute one block.

A fragile portion 4 which can be cut is provided between each block. The fragile portion 4 is cut from both sides in the width direction of the brush base 2 as in the embodiment shown in FIG. For engraving grooves, leaving a central piece, the central piece is formed so that the cut surface is depressed to the base end side after cutting,
This is to prevent a sharp cut surface due to the cutting from protruding from the tip of the block that has been cut to the tip side.

FIG. 3 shows a state in which a cap C is attached so as to smooth the cut end. In this case, after cutting the fragile portion 4, the cut surface at the end is slightly uneven. Even if the result is obtained, it becomes smooth by attaching the cap C.

Furthermore, the one shown in FIG. 4 uses the jig G to cut the fragile portion 4. If the brush itself or the block is small, it is difficult to pinch and cut it with a finger. By using the tool G, it can be easily cut.

Although the above description has been made with reference to the use of a toothbrush-like brush, it is a matter of course that the tip-cutting brush according to the present invention can be applied to any brush.

[0018]

According to the present invention, the brush base is formed into a block by the above-mentioned structure, and the block at the end of the brush which is severely damaged is cut and removed, and the next block is located at the end. If the hair is damaged, the tip block can be cut to make it look like a new one, and it can be used repeatedly with a single brush.The tip block can be cut according to the intended use, so it can be used in different applications. It has a very significant effect.
