It is more flexible than the member and can be a layer having at least antibacterial performance against E. coli and antistatic performance.

  In this case, in order to enhance the decorativeness of the prostate massager, the base layer in the surface coating layer may be a color paint layer, and the finishing layer may be a transparent or translucent layer. Alternatively, a decorative layer may be formed between the base layer and the finishing layer. For example, a pattern such as a pattern or a logo can be formed on the base layer itself. Or the decoration layer which printed the pattern, the logo, etc. in color on the surface of a base layer can be formed. By doing so, the decorativeness can be maintained without causing color fading and the like because it is protected by the transparent finish layer.

  In addition, the base layer and the finish layer may be generally a coating layer formed by baking. Alternatively, the underlayer can be a coating layer formed by baking and the finish layer can be a film deposition layer formed by vacuum-depositing a resin film on the surface of the underlayer.

  Next, the insertion portion main body member can be manufactured from a polycarbonate resin. In this case, the base layer may be a two-component curable acrylic polyurethane resin paint layer, and the finish layer may be an antibacterial agent and an antistatic agent added to the two-component curable polyurethane resin paint layer. desirable.

  Embodiments of a prostate massager to which the present invention is applied will be described below with reference to the drawings.

  Referring to FIG. 1, the prostate massager 1 according to the present embodiment includes a rod-shaped insertion portion 2 with a rounded tip inserted into the large intestine, and a rear end of the insertion portion 2. Is connected to a narrow-diameter constricted portion 3, and a grip portion 4 extending in an orthogonal direction is connected to the rear end of the constricted portion. The prostate massager 1 having this configuration includes a resin molded body 5 and a surface coating layer 6 that covers the entire surface of the resin molded body 5. It is also possible to use a metal cylindrical body instead of the resin molded body 5.

  In this example, as shown in FIG.1 (b), the surface coating layer 6 of the insertion part 2 is the base layer 7 formed in the surface 5a of the resin molding 5 which consists of polycarbonate resin, and the surface of this base layer 7 It is a coating layer having a two-layer structure comprising the finishing layer 8 formed in the above. The constricted portion 3 and the grip portion 4 can be the same surface coating layer 6, but can also be a single layer or multiple surface coating layers made of different materials. The underlayer 7 is for enhancing the adhesion between the resin molded body 5 and the finishing layer 8 and is a layer colored yellow, skin color or the like. The finishing layer 8 is a transparent layer having a surface property that is softer than the resin molded body 5 (insertion body member), and has many antibacterial properties against Escherichia coli (S. aureus) and predetermined antistatic properties. It is a functional layer.

The base layer 7 in this example is a coating layer of a two-component curable acrylic polyurethane resin paint, and the finishing layer 8 is a coating layer in which an antibacterial agent and an antistatic agent are added to the two-component curable polyurethane resin coating layer. . Specifically, the two-component curable acrylic polyurethane resin paint used as the underlayer 7 is
Titanium oxide,
toluene,
Xylene,
It contains ethylbenzene and methyl isobutyl ketone as main components.

The two-component curable polyurethane resin paint used as the finishing layer 8 is
Isobutyl acetate,
Meryl isobutyl ketone,
Diisobutyl ketone,
Silicon dioxide,
It contains toluene and ethyl acetate as main components.

  Further, as described above, an antibacterial agent and an antistatic agent are added to the coating material of the finishing layer 8, and as the antibacterial agent, for example, a material containing silver oxide can be used. Can use an ion conductivity conductivity-imparting agent. Moreover, as a coating liquid used for the finishing layer 8, what contains coating diluents, antibacterial agents, and antistatic agents, such as the coating material of the said structure, a hardening | curing agent, and thinner, can be used, for example.

  Here, in this example, in order to enhance the decorativeness of the prostate massager 1, the base layer 7 in the surface coating layer 6 is a layer of a color paint such as yellow or skin color, and the finishing layer 8 is a transparent layer. It has become. Alternatively, it is also possible to perform color printing such as a pattern or a logo on the surface of the underlayer 7 and form the finishing layer 8 thereon. In this example, as will be described later (see FIG. 2), the base layer 7 and the finish layer 8 are coating layers formed by baking, but the coating layer formed by baking coating the base layer 7. The finishing layer 8 can be a film deposition layer formed by vacuum deposition of a resin film on the surface of the base layer.

  Next, an example of a procedure for applying the surface coating layer 6 of the insertion portion 2 will be described with reference to a schematic process diagram shown in FIG. First, after drying the base material (resin molded body 5) of the prostate massager 1 before the surface coating, the release agent, oil, etc. adhering to the surface are wiped off with alcohol (ST1: drying and degreasing process). . Next, the unnecessary portions that do not need to form the surface coating layer 6, in this example, the surfaces of the constricted portion 3 and the grip portion 4 are masked (ST2: masking step), and then air is applied to the substrate surface. Blowing is performed to remove dust adhering to the substrate surface (ST3: air blowing process).

  After the surface treatment of the surface of the base material is performed in this way, undercoating is performed to form the underlayer 7 on the surface (ST4: undercoating step). For example, a two-component curable acrylic polyurethane resin paint is applied by hand coating. The base layer 7 is formed by heating and drying the coating after application (ST5: drying step).

  Next, air blow is performed on the surface of the underlayer 7 to remove dust and the like adhering to the surface (ST6: air blow process), and then a finish layer 8 is formed on the surface of the underlayer 7 Overcoating is performed (ST7: topcoating step). For example, a two-component curable polyurethane resin paint to which an antibacterial agent and an antistatic agent are added is applied by hand coating. The finish layer 8 is formed by heating and drying the coating after application (ST8: drying step).

In the insertion part 2 of the prostate massager 1 obtained in this way, the finishing layer 8 made of polyurethane resin is more flexible than the insertion part main body member (resin molded body 5) made of polycarbonate resin, and the feel to the skin is improved. It was confirmed that the same feel as that of the silicone insertion part was obtained. In addition, the antibacterial activity value (JISZ2801 antibacterial test method) was 2.2 or more and 5.1 or more against E. coli, and it was confirmed that sufficient antibacterial properties were imparted and it was hygienic. Furthermore, the average value of the electrical resistance value (IEC method) was 2.43 × 10 ⁻¹⁰ Ω, and it was confirmed that foreign matters such as dust and dust are difficult to adhere and are hygienic. In addition to this, since the prostate massage device 1 is odorless unlike that made of silicone or the like, it has been confirmed that the patient does not feel uncomfortable.

(Other embodiments)
In the above example, a surface coating layer having a two-layer structure of an underlayer and a finishing layer is employed. Instead of this, it is also possible to use a surface coating layer consisting only of the above finishing layer. In this case, a logo, a pattern, or the like may be printed directly on the surface of the insertion portion main body member (resin molded body 5). Further, as the surface coating layer, a three-layer structure of an underlayer, an intermediate layer, and a finishing layer can be adopted, and the intermediate layer can be a decorative layer on which a logo, a pattern, etc. are formed.
