Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a cleaning tool suitable for removing dirt that is strongly stuck to a container or the like.

[0002]

2. Description of the Related Art Soft open-cell foams have been generally used as a material for cleaning tools because they have flexibility and weak elasticity, and they preferably contain water, detergent solution and the like. However, since it is easily worn and has no hardness, it is not suitable for removing dirt that is firmly stuck. On the other hand, tortoise scrubbers and brushes have hardness and have been used as a cleaning tool suitable for removing sticky dirt, but the elasticity of the hard thread as a rubbing material scatters dirt and water or detergent. It has a weak point that it contains poor solution.

The above has been pointed out for a long time, and as a material for compensating for the low scraping ability of the soft open-cell foam, a soft open-cell foam laminated with a hard non-woven fabric has been widely used as a kitchen appliance. On the other hand, many devices have been devised and invented to compensate for the defects of both the sponge scrubbing brush, the tortoise stirrup, and the brushes, but they have not spread as general daily necessities.

In Japanese Utility Model Application Laid-Open No. 54-60950, there is a scrubbing brush which is made of polypropylene material fibrous material 2 and is kept standing at an appropriate interval to stand up innumerably and penetrates from one side of the synthetic resin foam plastic main body 1 to the opposite side. . Further, in Japanese Patent Laid-Open No. 59-49726, there is a cleaning tool characterized in that a hard rubbing body and a soft open-cell foam are integrated in a positional relationship such that both can simultaneously contact the cleaning surface. The soft open-cell foam according to claim 2 is provided in a ring shape on the outer peripheral portion of the hard rubbing body,
In the cleaning tool, a hard rubbing body is embedded in a soft open-cell foam.

In the products according to the above inventions and inventions, the soft material among the materials used as the rubbing body is arranged on the outer side of the rubbing surface and the side surface of the rubbing body. Since a soft open-cell foam such as a sponge has a significantly higher rate of abrasion and deterioration due to rubbing than a hard fiber, it is unsightly in appearance although the hard rubbing body is not deteriorated. This shortens the service life in use, raises the economic burden, and hinders its spread in real life. Japanese Patent Application Laid-Open Nos. 62-233137 and 11
-216017 and Japanese Patent Laid-Open No. 2000-107110,
The same can be said.

In Japanese Utility Model Laid-Open No. 61-23965, there is a washing tool characterized in that a group of holding members for holding water and detergent and a group of hairs required for washing are appropriately arranged and assembled. Nothing other than the above is mentioned with respect to the positional relationship between the holding member and the bristles, and how to solve the difference in deterioration speed between the holding member and the bristles is not mentioned. The problem is different from that of the present invention, but it has a side part similar to the shape.
The laminated scrubbing brush of 7228 does not mention the difference in deterioration rate due to the difference in material.

[0007] Turtle child scrubbing is suitable for removing sticky dirt, and although it has been used and used habitually by Japanese people for a long time, it has a bad feel when it is held, and it has a bad appearance. The layer is not popular.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described with reference to the drawings. In the present invention, a plurality of soft open-cell foams having different hardnesses, fibrous yarns, hard yarns, non-woven fabrics, wires, and the like, which can be used as a cleaning tool, are mixed with a plurality of materials having different properties and are rubbed together. 4 and the cut surface on which the different materials used are exposed is referred to as a rubbing surface 5. A material protection part 6 is formed on the side surface of the rubbing body 4.

FIG. 1 is a perspective view of a first embodiment including a partial cross section. Sliding body 4 in which the sliding material 2 penetrates the water retaining material 1 and is scattered
The cut surface where the different materials used are exposed together 5
And A material protection part 6 is formed on the outer side surface of the rubbing body 4. As the water retaining material 1, a material having a water retaining ability such as a soft open-cell foam, a fiber thread or a non-woven fabric is used. Wire for the scraping material 2,
A hard yarn, a non-woven fabric having hardness, or a relatively hard material among soft open-cell foams is used. The protective portion 6 is made of rubber, synthetic resin, or metal.

The soft open-cell foams and fibers used in the water retention material 1 often contain water and a detergent solution and are suitable for cleaning soft and oily stains. On the other hand, the hard thread or wire used for the rubbing material 2 is suitable for scraping off the hard and sticky dirt. According to the rubbing by the rubbing body 4 in which both are mixed,
Since the water retaining material 1 contains a detergent and supplies the detergent solution to the rubbing surface 5, the rubbing material 2 scrapes off the adhered oil stains, so that a high cleaning effect can be obtained.

In the products according to the conventional invention, since the soft material among the materials used as the rubbing body is arranged on the outside of the rubbing surface and the side surface of the rubbing body, the rubbing material is Although it did not hurt, the soft part deteriorated quickly due to abrasion and the like, and the appearance was deteriorated. As a result, the actual service life is extremely short, which is uneconomical and delays its spread. In the present invention, by providing the protective portion 6 on the side surface of the sliding member 4, deterioration of the soft water retaining material 1 is prevented, and by reducing the difference in the service life of the water retaining material 1 and the sliding friction material 2, economically. Make it an excellent cleaning tool.

FIG. 2 is a perspective view of a second embodiment including a partial cross section. The cut surface on which different materials used by the sliding friction body 4 in which the sliding friction material 2 and the intermediate material 3 penetrate through the water retention material 1 are scattered is referred to as a sliding friction surface 5. A material protection part 6 is formed on the outer side surface of the rubbing body 4. As the intermediate material, a cloth, a non-woven cloth, or the like having a water-holding capacity and hardness, which are substantially intermediate between the water-holding material 1 and the sliding friction material 2, is used. The effect is almost the same as that of the first embodiment, but after the rubbing material 2 is roughly scraped and the dirt is scraped off, the intermediate material 3 can be finely rubbed.

FIG. 3 is a perspective view including a partial cross-section of the third embodiment, in which the rubbing member 2 surrounds the side surface of the rubbing member 4 in a wall shape to form the protective portion 6 of the water retaining member 1. Is. Since the rubbing material 2 covers the side surface of the water retaining material 1, the water retaining material 1 is not strongly pressed directly against the article to be cleaned. This makes it possible to prevent the water retaining material 1 from deteriorating faster than the rubbing material 2, unlike the cleaning tool in which the water retaining material is arranged outside the rubbing material as seen in the prior application.

FIG. 4 is a perspective view including a partial cross section of the fourth embodiment, in which the intermediate material 3 surrounds the side surface of the sliding friction body 4 in a wall shape to form the protective portion 6 of the water retaining material 1. is there.
