Abstract

PROBLEM TO BE SOLVED: To provide a sponge scrubbing brush which is hygienic and is easily usable by forming the sponge scrubbing brush so as to prevent the surface of the scrubbing brush from blackening and appearing ugly and to prevent the generation of mold and fungi. SOLUTION: Metallic particulates of copper, titanium oxide and alumina, or the like, are incorporated into a soft synthetic resin foam of urethane, by which the sponge scrubbing brush is so formed as to exhibit sterile and antimicrobial properties.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sponge scourer used for washing a body when taking a bath or for washing dishes and pots in a kitchen.

[0002]

2. Description of the Related Art A conventional sponge scourer used for washing a body or for washing dishes and pans in a kitchen includes a sponge scourer obtained by expanding and foaming a soft synthetic resin such as urethane foam. .

[0003]

The above-mentioned conventional sponge scrubbers are particularly suitable for cleaning and polishing body washers or dirt due to their excellent water absorption, water retention, elasticity and flexibility. It has an excellent effect and is inexpensive and suitable for practical use.However, it has poor abrasive power, and its surface becomes dark and ugly in an early stage, and when left in a humid place, mold and fungi are generated. There was a problem that it became easy and was not preferable from a hygiene point of view.

SUMMARY OF THE INVENTION The present invention has been made in view of the problems of the prior art, and has as its object to increase the polishing power of a sponge scourer while utilizing the properties of a soft synthetic resin foam, and to improve the antibacterial properties. An object of the present invention is to provide a sponge scrubber that is hygienic and excellent in quality by exhibiting properties and eliminating the occurrence of mold and fungi.

[0005]

In order to achieve the above object, a sponge scourer according to the present invention comprises a soft synthetic resin foam such as a urethane sponge mixed with fine particles of metal such as copper or titanium oxide or aluminum. It is.

In addition, a soft synthetic resin foam such as a urethane sponge may be mixed with an aluminum powder and a catechinsan powder extracted from tea leaves.

Further, it is preferable to mix aluminum granules and granules such as shells, shrimp and crab shells into a soft synthetic resin foam such as urethane sponge.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION A sponge scrubber is used for soft synthetic resin foam since fine particles of metal such as copper are mixed alone or mixed with fine particles of metal such as shells in a uniform manner. These fine particles are distributed and exposed on the entire surface in a floating manner. Therefore, when cleaning the body or cleaning the dishes and the like, the polishing force acts more strongly than the conventional sponge. Since such a polishing force is exerted in the softness of the sponge, there is very little damage to tableware and the like. Also, even if it was left in a humid place for a long time, the antibacterial effect was strong, so that no mold was generated and the surface did not become dark.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment will be described below with reference to the accompanying drawings.
1 and 2, reference numeral 10 denotes a foam made of a soft synthetic resin and has closed or continuous cells 10a. The soft synthetic resin foam 10 has a porous structure in which a foaming agent is added at a high temperature in a closed mold and foamed at a high magnification, and is cut into a predetermined shape after foam molding. As such a soft synthetic resin foam, a urethane resin, a phenol resin, an epoxy resin, or the like is used.

The fine metal particles 1 are mixed into the above-mentioned soft synthetic resin foam 10 alone or by adding powders such as shells so as to be uniformly dispersed. Copper or copper alloy, titanium oxide, stainless steel, and aluminum are used as the metal fine particles. As the granular material 2 such as a shell, oyster hulls are preferable, and those obtained by drying shrimp and crab shells into granular materials are used.

It is known that copper has high antibacterial properties, and shells, shrimp, and crab shells also have strong antibacterial properties.
Preferably, it is blended at a total weight of 10 to 30 percent.

Since aluminum is less antibacterial than copper, when mixing aluminum fine particles into the foam 10, powder of oyster shells, shrimp and crab or catechinsan powder 21 extracted from tea leaves should be used. Is mixed. According to the experiment, catechinsan is more antibacterial than shells, shrimps and crab shells, and when catechinsan powder was mixed with aluminum into foam 10 and foamed, the whole color changed to green. When the amount of catechinsan was reduced and the amount of fine aluminum particles was increased, the silver color became stronger.

When the copper fine particles were mixed into the urethane foam, a slightly reddish brown or light brown colored product was obtained.

[0014]

When a body wash is performed with a sponge scrubber and a dishwasher or the like is washed with washing water, it has been found that the polishing effect is stronger than that of a conventional sponge scrubber and the washing effect is higher. Even if the polishing power was strong, the surface of tableware and the like was not damaged. Even when left in a humid bathroom having a humidity of 60 to 80% for 3 to 4 days, no mold was generated on the surface of the sponge scourer, and the surface did not become dark.

[0015]

According to the present invention, the entire surface of the sponge scrubber is reddish, and the polishing power can be enhanced by the fine metal particles. In addition, it is possible to provide a clean and clean sponge scourer, while preventing blackening and generation of mold and the like.

[0016] Further, because of the constitution of the second aspect, the antibacterial property is further exerted, and a new type of sponge scourer can be provided at low cost.

Further, since the present invention is configured as in claim 3, a great effect can be obtained by using an inexpensive material, and an antibacterial scourer can be provided at a low cost.
