Description

[Detailed Description of the Invention] The present invention relates to the structure of a household scrubbing brush that is elastic, flexible, and has excellent water removal properties.

Traditionally, many household scrubbers are made by laminating a non-woven fabric scrubber cut into long lengths of an appropriate width with thick urethane foam cut into long lengths with an appropriate width, and then cut into sizes that are easy to grip. However, since the urethane foam itself of such two-layer scrubbers is very soft, they are weak and difficult to remove stubborn stains when cleaning dirty dishes, kitchen utensils, daily necessities, etc. There is a drawback.

Therefore, if the thickness of the nonwoven fabric scrubber with abrasive grains attached is increased to increase stiffness, air permeability and water permeability will be poor, water removal properties will also be reduced, and drying will be difficult and unsanitary. Further, urethane foam has problems such as its shape being lost as the nonwoven scrubber expands and contracts, resulting in a very unsightly appearance.

The present invention improves the above-mentioned drawbacks by interposing a synthetic resin sheet molded into a concave and convex shape that is continuous into the middle layer of a three-layer household scrubbing brush, thereby giving the scrubber elasticity and stiffness as well as providing ventilation. To provide a hygienic household scrubbing brush with good properties and drainage properties.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a perspective view of one embodiment of the household scrubber of the present invention, in which the upper layer a contains abrasive grains such as alundum, carborundum, and gold steel sand, or aluminum foil and aluminum powder; A hard type scrubber made of non-woven fabric with a thickness of 5 to 30 mm, which is formed by fixing granules to a fiber web selected from fibers such as nylon fiber, polyester fiber, polypropylene, polyvinylidene chloride, etc. with a resin or synthetic rubber binder. 1, and the intermediate layer b is composed of a concavo-convex molded body 2 of a synthetic resin plate formed into a continuous concavo-convex shape.
As shown in FIG. 2, the continuous uneven molded body 2 of the synthetic resin plate is a sheet or plate-like material with a thickness of 0.3 to 5 mm selected from synthetic resins such as polyethylene, polypropylene, polyester, polyvinyl chloride, etc.
Concave portions 3 and convex portions 4 are regularly repeated and successive.

The synthetic resin plate may be made of high-density foam, or may be made of a material mixed with abrasive grains in advance.

For the lower layer c, a hard type scrubber 1 made of non-woven fabric containing the same abrasive grains as the layer a is used, and each layer is bonded together with an adhesive to form a three-layer household scrubber.

By using a synthetic resin plate with circular holes or mesh-shaped holes punched in advance, the water permeability, air permeability, and drainability of the scrubbing brush can be further improved. Furthermore, a concavo-convex molded body may be formed by forming a synthetic resin plate into a continuous wave shape.

Further, FIG. 3 shows another embodiment, in which the hard type scrubber 1 made of non-woven fabric is used for the upper layer a, the intermediate layer b is formed by similarly forming an uneven molded body 2 of a synthetic resin plate, and the unevenness is arranged in the longitudinal direction, and the lower layer c is a bulky non-woven fabric scrubber made of a web made of fibers such as nylon, polyester, polypropylene, polyvinylidene chloride, etc., by needle punching or a binder or a combination of both, or A soft type scrubbing brush 5 using resin foam is constructed, and the layers are bonded together with adhesive to form a household scrubbing brush.

Note that the upper layer a may be composed of a soft type scrubber instead of the hard type nonwoven fabric scrubber, and in addition, the combination of the nonwoven fabric hard type scrubber and soft type scrubber used for the upper layer and the lower layer can be implemented in the following manner.

Upper layer hard type, lower layer hard type Upper layer hard type, lower layer soft type Upper layer soft type, lower layer hard type Upper layer soft type, lower layer soft type Since the present invention is constructed as described above, when using it, it is necessary to use a synthetic resin plate constituting the intermediate layer. Uneven molded body 2
It is highly elastic, has a firm body, and is easy to handle.Using its elasticity, it can easily remove rust and dirt that is hard to remove from the object being cleaned, and the cleaning can be performed without using extra force. Operability has been greatly improved. In addition, concave grooves made of synthetic resin plates are formed in the middle layer on both sides of the upper and lower layers, allowing water to be easily discharged from the grooves, resulting in good drainage properties, excellent breathability, and reduced drying time. It has practical effects such as being quick and very hygienic.
