Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a brush used for applying wax, cleaners, paints and the like.

[0002]

2. Description of the Related Art Conventionally, as a brush used for applying wax, cleaner, paint, etc., a sponge brush is adhered and fixed to the front surface of a substrate, and a liquid supply source connecting portion for connecting to a liquid supply source is provided on the rear surface. A brush having a structure in which a through hole that connects the liquid supply source connecting portion and the front surface is formed in the substrate is known.

In the brush having the above-mentioned structure, a container containing a liquid such as wax is connected to the liquid supply source connecting portion, the wax is sent out from the container to the liquid supply source connecting portion, and the liquid is passed through the holes to the front surface. It is designed to be introduced to the side and penetrated into the sponge brush.

[0004]

According to the brush having the above structure, the liquid introduced from the through hole of the substrate to the front side is concentrated and penetrates into the sponge brush portion near the opening of the through hole. However, it does not spread evenly over the entire sponge brush, and thus uneven coating is likely to occur, which is not convenient.

An object of the present invention is to provide a sponge brush capable of permeating the supplied liquid uniformly and so as to spread throughout the sponge brush.

[0006]

In order to achieve the above object, the present invention has a sponge brush on the front surface of a substrate and a liquid supply source connecting portion connected to a liquid supply source on the rear surface,
A brush for introducing the liquid fed through the liquid supply source connecting portion to a front surface side through a through hole formed in a substrate and supplying the sponge brush, wherein the through hole is provided on the front surface of the substrate. It is characterized in that a long groove is formed so as to be opened in the opening, the opening portion of the long groove is covered with a dispersion plate, and both side portions in the longitudinal direction of the long groove are opened to form a liquid discharge port.

With this structure, when the liquid supply source is connected to the liquid supply source connection portion and the liquid is sent out from the liquid supply source, the liquid is formed on the front surface of the substrate through the through hole formed in the substrate. It is introduced into the long groove. The liquid introduced into the long groove is guided to both side portions in the longitudinal direction of the long groove by the dispersion plate covering the opening portion of the long groove, and is dispersed and discharged by the liquid discharge ports opening at both side portions of the long groove. Therefore, the liquid permeates the sponge brush substantially uniformly and widely throughout the sponge brush.

[0008]

1 and 2 show an embodiment of a brush according to the present invention. In the figure,
Reference numeral 1 is a substrate, 2 is a sponge brush adhered and fixed to the front surface of the substrate 1 with an adhesive, and 3 is a cylindrical liquid supply source connection portion provided on the rear surface of the substrate 1. The substrate 1 is formed in a rectangular shape, and a peripheral wall 4 protruding toward the front side is formed around the substrate 1, and a sponge brush fitting recess 5 is formed on the front surface of the substrate 1 by the peripheral wall 4.

Reference numeral 6 denotes a liquid supply path of the liquid supply source connecting portion 3, and reference numeral 7 denotes a through hole penetratingly formed in the substrate 1. The liquid supply path 6 and the front surface of the substrate 1 are communicated with each other, and the liquid supply path is provided. The liquid sent to the substrate 6 is introduced to the front surface of the substrate 1, and is formed at a position approximately at the center of the substrate 1 in the longitudinal direction.

Reference numeral 8 denotes a long groove formed on the front surface of the substrate 1 in the longitudinal direction of the substrate 1, and the through hole 7 is opened at a substantially central position in the longitudinal direction of the groove bottom of the long groove 8. 9 is the long groove 8
Is a dispersion plate that covers the openings of the liquid ejection section 10 and opens both side portions of the long groove 8 in the longitudinal direction. In this example, the dispersion plate 9 shorter than the long groove 8 covers the central portion of the long groove 8 and opens both sides of the long groove 8 to form the liquid ejection port 10. In the cylindrical liquid supply source connecting portion 3 provided on the rear surface of the substrate 1, the mouth portion of the container 11 containing the liquid serving as the liquid supply source is screwed to the tip thereof. .

According to this structure, when the liquid is sent from the container 1 to the liquid supply source connecting portion 3, the liquid is supplied to the liquid supply path 6
And is introduced into the long groove 8 through the through hole 7 formed in the substrate 1. The liquid introduced into the long groove 8 is guided to both sides in the longitudinal direction of the long groove 8 by the dispersion plate 9 covering the central portion of the long groove 8, and from the liquid discharge ports 10 opening at both sides of the long groove 8. It is dispersed and discharged, and penetrates into the sponge brush 2 that is adhesively fixed to the front surface of the substrate 1, so that the liquid penetrates into the sponge brush 2 substantially uniformly and widely.

FIG. 3 shows another embodiment of the brush according to the present invention. In this example, the dispersion plate 9 is formed to have a size that covers the entire opening of the long groove 8, and the plate surface of the dispersion plate 9 is located on both sides of the long groove 8 when the long groove 8 is covered with the dispersion plate 9. A plurality of liquid discharge ports 10 that communicate with the long grooves 8 and discharge the liquid introduced into the long grooves 8 are formed in the longitudinal direction.

According to this structure, the liquid introduced into the long groove 8 has a plurality of liquid discharge ports 1 formed in the dispersion plate 9.
Since it is dispersed and discharged from 0, the liquid discharged from the liquid discharge port 10 permeates the sponge brush 2 more uniformly and widely.

[0014]

As described above, according to the brush of the present invention, the sponge brush is provided on the front surface of the substrate, and the liquid supply source connecting portion connected to the liquid supply source is provided on the rear surface. A brush that introduces the liquid fed through the source connecting portion to a front surface side through a through hole formed in the substrate and supplies the liquid to a sponge brush, the through hole being opened at the groove bottom on the front surface of the substrate. Thus, since the long groove is formed, the opening of the long groove is covered with the dispersion plate, and both sides in the longitudinal direction of the long groove are opened as the liquid discharge port, the wax fed from the liquid supply source,
Liquids such as cleaners and paints are dispersed and ejected on the sponge brushes, and the liquids can be permeated into the sponge brushes substantially uniformly and widely, and thus the coating operation can be easily performed. effective.
