[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a brush, and more particularly to a brush comprising a soft base and a somewhat hard brush-like member.

[0002]

2. Description of the Related Art Conventional brushes for home use include kitchens,
Often one or two layers of flexible plastic foam used for cleaning bathrooms, toilets, etc. are used. Since these soft plastic foams mainly have open cells, they have the advantage that they have good liquid retention properties for water or water containing detergent or paint, and that they do not damage the surface of the object to be cleaned even if they are rubbed.

However, dirt firmly adhered to kitchen sinks, bathroom tubs, tiles, toilet bowls, tiles, etc., can be easily removed with a conventional brush made of a soft plastic foam alone even with a detergent. Since it was not, it was necessary to separately remove sticking dirt with a slightly hard brush such as a turtle scourer. Finish wiping is later performed with a soft plastic foam. However, it is cumbersome to always prepare a plurality of brushes for each application, and there is a problem in that it is difficult in terms of space in an apartment house in a narrow urban area.

The inventor of the present invention thought that the cleaning operation could be performed with a single brush, and as a result of intensive studies, reached the present invention.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a brush which does not require a separate bristle brush, is easy to remove sticking dirt when used alone, and is capable of finishing and wiping at the same time.

[0006]

According to the present invention, an uneven portion is provided on a substrate working surface made of a soft plastic foam, and a brush-like member having at least a bundle of fibers harder than the substrate is provided upright in the concave portion. The brush (Claim 1), the brush (Claim 2) according to Claim 1, wherein the brush-like member is erected near the center of the concave portion of the working surface of the base, and / or the surface opposite to the working surface of the base.
3. The method according to claim 1, wherein an elastic shape retaining member having a rigidity higher than at least the base is fixed inside the base.
A brush according to claim (claim 3) is provided.

Hereinafter, the present invention will be described in detail using embodiments.

[0008]

FIG. 1 is a perspective view of an embodiment of the present invention with the working surface as the upper surface, FIG. 2 is a cross-sectional view taken along the line AA of FIG. 1, FIG. 5 is a perspective view of another embodiment with a handle, FIG. 6 is a sectional view of another embodiment, and FIG. 7 is a sectional view of a conventional example.

In FIGS. 1 and 2, 1 is a base made of a soft plastic foam, 1A is a plastic foam of a different kind,
Reference numeral 2 denotes a convex portion of the base, 3 denotes a concave portion of the base, 6 denotes a brush-like member, 8 denotes an adhesive, and 10 denotes a shape-retaining member.

The working surface of the embodiment shown in FIG.
And the base recesses 3 each having a brush-like member 6 rising vertically at the bottom are arranged alternately and neatly.

As can be seen in FIG. 2, a shape-retaining member 10 is fixed to the lower surface of the base 1 with an adhesive (not shown).
The lower part is fixed to the shape retaining member 10 with an adhesive 8 and penetrates through the base 1 made of a porous soft plastic foam. Therefore, the brush-like member 6 has higher rigidity than the soft base 1.

In general, an inexpensive plastic plate such as hard PVC or PP is used as the shape retaining member, but a metal plate such as Al may be used.

Further, as shown in FIG. 2, a different kind of plastic foam, which is slightly harder than the base 1 reinforced with metal fibers such as stainless steel, can be attached to the back surface of the shape retaining member 10.

If the shape retaining member 10 is fixed to the tip of another plastic handle 12 as shown in FIGS.
It can be used as a brush for cleaning the toilet or for cleaning the body of a car.

In addition, the entire shape can be flat, disk, elliptical, column, or tubular (roll).

In the present invention, the tip of the brush-shaped member 6 is generally retracted rather than the base convex portion 2. However, when the brush-shaped member 6 is relatively soft (but harder than the base 1), Convex part 2
Even when using the same level or slightly protruding ,
When the brush is strongly pressed in the finishing stage, the brush-like member lies down, so that the object to be wiped is scarcely damaged. There is also an embodiment having a cross section as shown in FIG. 6, and a similar effect can be obtained by wiping in the direction of the arrow.

[0017]

According to the present invention, all of the above objects are achieved. That is, the dirt fixed to the surface of the object to be cleaned can be removed with a relatively high-rigidity brush-like member by pressing, and the final cleaning can be performed with a base made of a soft plastic foam.
The benefit is that only one brush is needed.
