Abstract

PURPOSE:To obtain the always hygienic nail polishing device by allowing fine zeolite particles of, for example, synthetic zeolite, etc., which are formed by depositing metal ions, such as, for example, silver ions, copper ions and zinc ions, having an antibacterial property in pores, to exist in a polishing surface independently or after mixing the same with other fine ceramic particles. CONSTITUTION:The polishing surface 2 having prescribed ruggedness is formed on the left half of a base plate 1 consisting of a synthetic resin or metal and the other right half part is a crimping part 3. This polishing surface 2 is formed by applying a UV curing resin on the base plate 1 to form a coated film, sticking the zeolite having the antibacterial property on the thin adhesive agent film, and irradiating the coated film with UV rays by using a high-pressure mercury lamp to cure the above-mentioned resin, then immersing the base plate in an ethanol soln. to remove the uncured part of the resin. The synthetic zeolite formed by well holding the metal ions, such as silver ions, copper ions and zinc ions, having the antibacterial property in the crystal is used as the zeolite. This synthetic zeolite has the hardness higher than the hardness of the nails.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to, for example, a manual or electric nail polisher, and particularly relates to the configuration of its polishing surface.

[Prior art]

For example, in the conventional manual nail polisher, a large number of ceramic abrasive particles are fixed to a part of a substrate made of a metal plate in a predetermined shape to form a polishing surface with a predetermined roughness. . In addition, in the case of an electric nail polisher, a polisher (rotating body) has a large number of ceramic abrasive particles fixed to the surface to form a polished surface with a predetermined roughness.
Alternatively, a styler (reciprocating element) was constructed and attached to the rotating or reciprocating part of the nail polisher itself. [Problems to be Solved by the Invention] By the way, when the surface of the nail is polished, the stratum corneum on the surface of the nail is scraped off, and a portion of the stratum corneum gets into the narrow recesses of the polished surface. Since this stratum corneum is bolus and has hygroscopic properties, it adsorbs moisture from the air, which causes Escherichia coli. Staphylococcus aureus. Various miscellaneous bacteria such as Bacillus subtilis and Pseudomonas aeruginosa adhere and breed, making it unhygienic. After using a nail polisher, you can consider cleaning the polishing surface with a brush or sterilizing it with alcohol or ultraviolet light, but in reality, people often forget to do this or don't do it because it's a hassle. The disadvantage is that sanitary conditions cannot be maintained.

The purpose of the present invention is to eliminate such drawbacks of the prior art,
We always provide a hygienic nail polisher.

[Means to solve the problem]

In order to achieve the above-mentioned object, the present invention utilizes, for example, silver ions. Zeolite fine particles such as synthetic zeolite, in which antibacterial metal ions such as copper ions and zinc ions are supported in the pores by ion exchange, are present on the polished surface either alone or in combination with other ceramic fine particles. It is characterized by [Function] As mentioned above, by having an antibacterial agent present on the polished surface, moisture in the atmosphere is adsorbed due to clogging of the stratum corneum, and even if bacteria etc. adhere, the action of the antibacterial agent prevents the growth of bacteria. It can be suppressed or sterilized. Therefore, the polishing surface of the nail polisher can always be maintained in a sanitary condition.

〔Example〕

Next, embodiments of the present invention will be explained with reference to the drawings. FIG. 1 is a plan view of a nail polisher for explaining the first embodiment. As shown in the figure, a polishing surface 2 having a predetermined unevenness is formed on the left half of a substantially diamond-shaped substrate 1 made of synthetic resin or metal.
is formed, and the other right half is the supporting part 3. This polishing surface 2 is made of ultraviolet curable resin (manufactured by Dainichiseika Chemical Co., Ltd., product name Seirybeam EX-58520) with a viscosity of 800 to
This was adjusted to 2000 cps and applied onto the substrate 1 to form a coating film with a thickness of 0.1 mm. Zeolite, which has antibacterial properties and has a particle size of about 0.1 μm to 40 μm, is adhered to this adhesive thin film, and then a high pressure mercury lamp is used to
The ultraviolet curable resin is cured by irradiating it with ultraviolet rays with a wavelength of 365 nm for 5 seconds at an output of 1.0 cm". Thereafter, it is immersed in an ethanol solution to remove the uncured portion of the resin.

As the zeolite mentioned above, synthetic zeolite is preferably used. This synthetic zeolite has a three-dimensionally developed skeletal structure and has a Vickers hardness of about 200 to 400, which is higher than the hardness of nails. In addition, the chemical composition is generally xMa/no H AlzOx based on Alt03.
・ySift ・211tO, M represents an exchangeable metal ion, and n is its valence. Since some of the silicon is replaced with regular tetrahedral aluminum with a coordination number of 4, there is a shortage of positive ions, and to compensate for this deficiency, shodensho is added. Copper ion. Antibacterial metal ions such as zinc ions can be well retained within the crystal.
The synthetic zeolite has three-dimensional pores of 10 angstroms or less and a specific surface area of 150 m''/g, and zeolite A, zeolite X and zeolite Y are particularly suitable.

FIG. 2 is a perspective view of a nail polisher for explaining a second embodiment of the present invention. This nail polisher uses an approximately diamond-shaped elastic substrate 4 made of foamed urethane resin in the middle, and resin sheets 5a and 5b such as urethane sheets are attached to the upper and lower surfaces of the substrate, respectively. The triangular portion at the left tip of this upper resin sheet t-5a has a grain size of l30.
A polishing surface 6a with a grain size of "600" is present on the triangular portion of the right tip of the upper resin sheet 5a, and a polishing surface 6b with a grain size of "600" is on the triangular portion of the left tip of the lower resin sheet 5b.
A polishing surface 6C with a grain size of 1,000 and a polishing surface 6d with a grain size of 2,000 is on the triangular portion of the right tip of the lower resin sheet 5b.
are formed respectively. The polished surfaces 6a to 6d having different particle sizes are prepared by screening the particle sizes of synthetic zeolite fine particles (to which antibacterial metal ions are attached by ion exchange) and using a photopolymerizable resin such as an ultraviolet curable resin as a binder. It can be formed by

In the case of this example, the abrasive particles (zeolite particles) were fixed to the surface of the resin sheet 5 using a binder to form the abrasive surface. It is also possible to form a polishing surface by mixing it and forming it into a sheet. Incidentally, abrasive grains such as silicon dioxide or aluminum oxide can also be added together with the zeolite particles.

FIG. 3 and FIG. 4 are diagrams for explaining a third embodiment of the present invention. In this embodiment, a polishing bead 8 is removably set at the tip of the nail polisher body 7. On the polishing surface 9 of the polishing bead 8, zeolite fine particles having a predetermined particle size and carrying antibacterial metal ions by ion exchange are fixed, either alone or in a mixture with other polishing particles.

Although this embodiment shows a reciprocating type electric nail polisher using a styler (reciprocating element), it can also be applied to a rotating type electric nail polisher using a polisher (rotor).

〔Effect of the invention〕

The present invention has the above-described configuration, and can always keep the polished surface, which tends to absorb moisture due to the adhesion of the stratum corneum, in a sanitary state.

Furthermore, as shown in the examples, if a solvent-free photopolymerizable resin is used as a binder, there is no fear that residual organic solvents will have an adverse effect on cosmetics such as manicure.
