Abstract

To provide a robust washing brush whose bristle ends spread excellently and can effectively transmit to the bristle ends a user's force scratching off extraneous matters attached to a washed surface.MEANS FOR SOLVING THE PROBLEM: A washing brush 1 includes: a synthetic resin columnar core member 2; many bristle members 3 forming a cross section annular bristle member aggregate layer 4 on an outer periphery of the core member; a band member 5 binding the bristle members with the outer periphery of the core member 2; and a cap 6 covering the core member 2 and base ends side of the bristle members 3. The bristle member 3 is composed of an elastic synthetic resin monofilament that is wave-processed, and has a base end aligned with a base end 2a of the core member 2, and integrally thermally welded to the core member 2, and a tip end side extending beyond a tip of the core member 2. On the base end side where the core member 2 internally exists, a handle part 1a, where a user can grip by touching a top end 6c of the cap member 6 with a palm, is formed. On the tip side of the bristle member 3, a washing part 1b having yield strength allowing extraneous matters on a washed surface to be scratched off by an axial pressing force of the bristle member, is formed.SELECTED DRAWING: Figure 2

Description

The present invention relates to a cleaning brush for quickly scraping off dirt adhering to cooking utensils, for example, in a kitchen of a Chinese restaurant.

Conventionally, in order to improve the strength of a brush called "Sasara", which is made by cutting bamboo to a predetermined length and finely dividing the tip side of the bamboo in the axial direction to form a brush part, a brush fiber made of synthetic resin. Patent Document 1 describes a brush in which a handle portion is fixed to a base end portion in which a large number of brushes are bundled.
Further, Non-Patent Document 1 describes brushes bundled by crimping around the base end portions of brush fibers of a large number of synthetic resins with a metal pipe.

Japanese Unexamined Patent Publication No. 11-32837 Product name "Super Sasara" on the website of Tsukamoto Eikichi Shoten Co., Ltd. http://www.k-tsukamoto.co.jp/htmls/s_yougu/images/burasi.pdf

Since all of the above-mentioned conventional brushes have a structure in which a large number of synthetic resin brush fibers are simply bundled, the bristles do not easily spread when pressed against the surface to be cleaned, and the substantial contact area with the surface to be cleaned is sufficient. There is a problem that it cannot be secured and efficient cleaning cannot be performed. In addition, if the hair ends are made flexible by using thinner hair material in order to secure the spread of the hair tips, the rigidity will be insufficient, and the force to scrape off the deposits on the surface to be cleaned will be effective. There is a drawback that it is not transmitted.
Therefore, in the present invention, the bristles tend to spread in a substantially annular shape during use, a relatively large substantial contact area with respect to the object to be cleaned can be secured, and the force of the user to scrape off the deposits on the surface to be cleaned is applied to the bristles. The challenge is to provide a robust cleaning brush that can be effectively communicated to.

The cleaning brush 1 of the present invention for solving the above problems is made of synthetic resin and forms a columnar core material 2 and a hair material aggregate layer 4 having an annular cross section and a predetermined thickness on the outer circumference of the core material 2. A large number of hair materials 3 arranged in such a manner, a band member 5 that binds the hair materials 3 to the outer circumference of the core material 2, and a cap 6 that covers the core material 2 and the base end side of the hair material 3 over a predetermined length. Equipped with. The hair material 3 is made of a wave-processed elastic synthetic resin monofilament, and the base end is aligned with the base end 2a of the core material 2 and heat-welded so as to be integrated with the base end portion of the core material 2. It extends longer than the tip of the core material 2. On the base end side where the core material 2 is embedded, a handle portion 1a is formed so that the user can hold the top end 6c of the cap member 6 against the palm. On the tip end side of the hair material 3, a cleaning portion 1b having a yield strength capable of scraping off deposits on the surface to be cleaned is formed by a pressing force in the axial direction thereof.

According to the cleaning brush 1 of the present invention, since a large number of hair materials 3 are arranged so as to form an annular hair material assembly layer 4 around the core material 2, the surface to be cleaned is subjected to an axial pressing force. Even if the hair material has a relatively large yield strength capable of scraping off deposits, the hair tips are likely to diffuse evenly and roughly in an annular shape during use, and a relatively large substantial contact area with respect to the surface to be cleaned is provided. It has the effect of ensuring efficient cleaning.

It is a schematic front view of the brush which concerns on embodiment of this invention. It is a schematic vertical sectional view of the brush of FIG. FIG. 3 is a sectional view taken along line III-III of FIG. It is explanatory drawing of the use state of the brush of FIG.

An embodiment of the present invention will be described with reference to the drawings.
In FIGS. 1 to 3, the brush 1 is made of synthetic resin and is arranged so as to form a columnar core material 2 and a hair material aggregate layer 4 having a predetermined thickness having an annular cross section on the outer periphery of the core material 2. A large number of hair materials 3, a band member 5 that binds the hair materials 3 to the outer circumference of the core material 2, and a cap member 6 made of synthetic resin that covers the core material 2 and the base end side of the hair material 3 over a predetermined length. Equipped with.

The hair material 3 is made of a wave-processed elastic synthetic resin monofilament, and the base end is aligned with the base end 2a of the core material 2 and heat-welded 7 so as to be integrated with the base end portion of the core material 2. The tip side of the hair material 3 extends longer than the tip of the core material 2.

The cap member 6 includes a tubular portion 6a in which the base end side of the core material 2 and the hair material 3 is covered over a predetermined length, and the base end is closed, and a locking projection piece 6b protruding toward the base end side. It is adhered to the core material 2 and the hair material 3 with a two-component epoxy resin adhesive.

As shown in FIG. 4, a handle portion 1a is formed on the base end side where the core material 2 is embedded so that the user can hold the top end 6c of the cap member 6 against his / her palm.

On the tip end side of the hair material 3, a cleaning portion 1b having a yield strength capable of scraping off deposits on the surface to be cleaned is formed by a pressing force in the axial direction thereof.

In the illustrated embodiment, the core material 2 is made of nylon or polyacetal resin and has a columnar shape having a diameter of 25 mm and a length of 80 mm. The hair material 3 is made of corrugated monofilament made of nylon or PBT resin having a diameter of 1.2 mm. The length of the hair material 3 is about 250 mm to 230 mm, and the entire hair material 3 is diagonally cut on the tip side.

As shown in FIG. 2, of the two band members 5, the one on the tip side binds the hair material 3 around the core material 2 at a position of about 25 mm from the tip 2b of the core material 2 to the base end side. There is. Therefore, the hair material 3 is constrained by the band member 5, and while maintaining the annular gathering position along the outer circumference of the core material 2, the hair material 3 has a movable range A of about 25 mm on the tip side of the core material 2 and is slightly individual. By moving to, when the tip is pressed against the surface to be cleaned, it is possible to have an appropriate spread in a substantially annular shape with respect to the surface to be cleaned as a whole.

In order to obtain appropriate rigidity and elasticity, the hair material 3 preferably has a diameter of 1 mm or more and 2 mm or less, and 1.2 mm is optimal.

The length of the handle portion 1a in which the core material 2 is contained is 80 mm or more from the top end 6c of the cap, the diameter is 30 mm or more and 50 mm or less, and the thickness of the hair material assembly layer 4 formed on the outer periphery of the core material 2 is 5 mm. More than 12 mm is preferable.
