JP2000189345A - Toilet seat having good antifoulancy - Google Patents

Abstract

PROBLEM TO BE SOLVED: To dispense with another process such as coating or the like separately from a forming process, easily remove dirt adhering to an exposed component, and improve antifoulancy by forming at least one member of constitutive materials of an exposed component of a toilet seat such as a toilet stool seat by a resin molding in which a lubricant is mixed in the resin. SOLUTION: A constitutive material of exposed components of a toilet seat such as a toilet stool seat 1, a toilet seat 2 and a main body case 3 is formed by resin molding in which a lubricant is mixed in the base material resin. As a lubricant, cited are hydrocarbon lubricant such as paraffin wax or the like, fatty acid alcohol lubricant such as stearyl alcohol. Thus, the lubricant is mixed to improve lubricity of the resin molding surface, whereby a dirt made by dispersion or dissolution of faces and urine which mostly cause dirt of the toilet stool seat adheres to the component, the dirt can be simply removed to simplify cleaning, so that breeding of various bacteria whose nutrition source is dirt can be reduced, and the surface of the resin molding is prevented from being damaged by wiping in cleaning.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet seat or a local cleaning toilet seat having excellent antifouling properties.

[0002]

2. Description of the Related Art Conventionally, exposed components of a toilet seat such as a toilet seat sheet, a toilet lid, and a main body case or a local cleaning toilet seat are generally formed as follows.
Acrylonitrile-butadiene-styrene resin (hereinafter, referred to as
ABS) or polypropylene (PP)
).

[0003]

In the case of a conventional toilet seat or a local flush toilet seat, when a man urinates, the toilet seat is mainly used while the toilet seat is raised. Pissing may occur. In the case of stool, stool that has fallen into the toilet bowl rebounds water in the toilet bowl, and dirt and water may adhere to the back surface of the toilet seat sheet. Further, skin dirt such as sebum adheres to the surface of the toilet seat sheet and the toilet lid that come into contact with the skin during use.

[0004] As described above, there is a situation in which the toilet seat member is easily soiled in daily use. However, the composition of the stain component and the mechanism by which the resin molded article is stained are complicated and have not been sufficiently elucidated. In general, oils and oily components and proteins derived from the human body, dust, water and water-soluble components, detergents such as detergents, and the like, in the state of these components alone or in combination, Recognized as dirt. The state can be classified as follows. A state of being buried in the irregularities on the surface of the resin molding. The state due to the intermolecular attraction between the surface molecules of the resin molded article and the dirt molecules The state in which the surface molecules of the resin molded article and the dirt molecules are chemically bonded The state in which dirt has penetrated or diffused inside the resin molded article On the other hand, in the living environment, it is difficult to create a state in which no dirt is attached, it is difficult to get dirt, and if dirt is attached, the dirt attached It is important to say that it is easy to remove and easy to clean.

However, in the conventional cleaning method for removing these stains, when the resin molded article is made of ABS resin, the resin molded article is inferior in detergent resistance, so that solvent cracks occur when the resin molded article is repeatedly exposed to the detergent, or the resin molded article becomes PP. In the case of resin, there is a problem that the surface is scratched at the time of wiping because of poor scratch resistance.

[0006] The present inventors have intensively studied to solve the above problems. As a result, it is possible to mold under the same resin molding conditions as before by mixing a lubricant into the resin,
When stains were found, it was found that the stains were easily wiped off and the resin molded body surface was not damaged. Therefore, an object of the present invention is to provide a toilet seat or a local cleaning toilet seat having excellent antifouling properties.

[0007]

According to the first aspect of the present invention, there is provided a toilet seat, a toilet lid,
At least one member of a constituent material of an exposed component of a toilet seat such as a main body case is a toilet seat formed of a resin molded body in which a lubricant is mixed in a resin.

According to a second aspect of the present invention, there is provided a toilet seat including a toilet seat, a toilet lid, a main body case, and a cleaning nozzle. It is a local cleaning toilet seat made of a resin molded body mixed with a lubricant.

The invention according to claim 3 is characterized in that 0.03 to 5 parts by weight of a lubricant is mixed with respect to 100 parts by weight of the base resin.

According to the present invention, with the above-described structure, it is easy to remove dirt on exposed components such as a toilet seat sheet, a toilet lid, and a main body case, and it is easy to clean the toilet seat. Further, it can be molded under the same resin molding conditions as in the past, and does not require another process such as painting, drying, and curing. Further, since there is almost no decrease in surface hardness, a toilet seat having high antifouling property and scratch resistance can be provided even with the same structure as the conventional one.

[0011] Since dirt can be easily removed and cleaned, the growth of germs and the like, from which dirt becomes a nutrient source, also decreases.

Since dirt can be easily removed and cleaned, there is no need to use a detergent that is strong in cleaning. Even when a resin having poor detergent resistance is used as a base material, generation of solvent cracks or the like due to the detergent is eliminated.

Since it is easy to remove and clean dirt, there is no need to repeatedly rub with strong force during cleaning, and even if a resin having poor scratch resistance is used as a base material, scratches on the surface of the molded body may occur. Disappears.
