Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a surface sheet and a toilet device.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 5, a first film 2 made of silver or copper is formed on a resin film substrate 1, and a second film 3 of a phosphazene-based curable resin is further formed thereon. The antibacterial film sheet thus obtained is disclosed in
No. 52964.

According to the proposed antibacterial film sheet, a pinhole 4 is formed in the phosphazene-based curable resin as the second film 3, and silver or silver in the first film 2 is formed through the pinhole 4. Copper acts on bacteria attached to the surface and is said to have an antibacterial effect.

[0004]

However, Japanese Patent Application Laid-Open No.
In the antibacterial film sheet proposed in 352964, since the pinhole 4 is formed by a chemical reaction, the position, shape, and number of pinholes vary depending on reaction conditions (temperature, humidity, material, layer thickness, etc.). That is, it is difficult to control the formation of the pinhole. Therefore, the antibacterial effect was not stable and was unsuitable as an industrial product.

An object of the present invention is to solve the above-mentioned problems, to provide a surface sheet which is easy to manufacture, exhibits a stable antibacterial effect, and is suitable as an industrial product, and a toilet apparatus provided with the same.

[0006]

Means for Solving the Problems and Actions / Effects There are provided a base material, a first coating layer formed on the base material and having antibacterial properties, and a first coating layer formed on the first coating layer. It is a topsheet characterized by having a second coating layer formed, having rigidity, and having patterned irregularities. According to this topsheet, since the unevenness of the second coating layer is formed by patterning by screen printing or the like, the position of the unevenness,
Shape and number are stable. That is, it is easy to control the form of the unevenness. Therefore, the antibacterial effect is stable,
It is suitable as an industrial product. In addition, since the second film layer is formed with irregularities, it can flexibly respond to bending during transportation, and can avoid a decrease in design due to a trace of bending remaining.

The remote control device 130 includes an insulating substrate,
Each switch (not shown) mounted on the insulating substrate is built in, and an optical signal as an operation command is transmitted from the acrylic window 18 when each switch pressing surface is pressed.

FIG. 2 shows the top sheet 131 removed from the remote control device 130. As shown in FIG. 2, each switch pressing surface is provided with a two-stage embossing process (not shown) for improving the click feeling and forming tactile symbols, and an embossing process (not shown) for forming Braille is provided around these pressing surfaces. Processing has been applied, and all have improved operability.

FIG. 3 shows the remote controller 130 from which the topsheet 131 has been removed.

FIG. 4 shows a cross-sectional view of the topsheet 131. According to FIG. 4, the topsheet 131 is made of the base material 11.
(A film sheet made of polyethylene phthalate, pencil hardness H (JIS K-5400)), an easy-adhesion layer 12 made of urethane on the upper surface, and a first resin-made resin containing an antibacterial agent on the upper surface. The coating layer 13 and a second resin coating layer 14 having rigidity on the upper surface thereof and having irregularities of 200 mesh patterned by pattern printing (pencil hardness 2H (JIS K-5400))
Are formed.

An easy-adhesion layer 15 made of urethane is formed on the lower surface of the base material 11, a design layer 16 on which a design is screen-printed on the lower surface, a laminate 17 for protecting the design layer 16 on the lower surface, and a laminate 17 on the lower surface. A double-sided tape layer 18 is formed.

The production of the topsheet 131 may be performed, for example, as follows. The first coating layer 13 is laminated on one surface of the substrate 11. For lamination, first, the easy-adhesion layer and the first coating layer 13 are applied to one surface of the long roll-shaped substrate 11 by screen printing. Further, a second coating layer is applied by screen printing (after each printing step,
A drying step (irradiating high-energy rays such as hot air, ultraviolet rays, or electron beams to solidify the resin) is performed. Next, a pattern layer is screen-printed on the other surface of the base material 11. Next, the design layer is dried. Next, a laminate is put on the design layer. Finally, stick the double-sided tape. For the first coating layer and the second coating layer, a coating suitable for screen printing containing a synthetic resin (such as an acrylic resin) and a solvent as a coating film forming element is used. The paint used for the coating layer further contains an antibacterial agent, and the antibacterial paint containing the antibacterial agent is inoculated to the specimen with bacterial liquids of various bacteria such as Escherichia coli and Staphylococcus aureus. When the viable cell count is measured after 24 hours, it has the effect of reducing various bacteria to 1/100 or less.

The above-described embodiment can be variously modified without departing from the gist thereof.

(1) Top sheet 131 described with reference to FIG.
A fluorescent paint is used as a paint to be printed on the symbol layers 16 and 26. In this case, the symbol can be visually recognized even in a dark place.

(2) Top sheet 131 explained in FIG.
Instead of the double-sided tape layers 18 and 28, an adhesive is screen-printed.

(3) The second coating layer illustrated in FIG.
225 mesh instead of 200 mesh. In this case, the mesh is not conspicuous and the design is not impaired.

(4) The second coating layer illustrated in FIG.
Instead of the mesh, a continuum of characters (for example, a product logo) may be used.

FIG. 6 is an explanatory diagram for explaining the detailed structure of the double-sided tape. The double-sided tape shown in FIG. 6 controls the adhesive force on one side. Since a base material obtained by laminating an acrylic foam and a polyester film is used and the adhesive strength on both sides is different, both can be peeled off and can be peeled off neatly.

Further, the thickness of the tape is as thin as 0.25 mm, the color is inconspicuous in gray, and it is most suitable for a surface sheet in which design is important. It can be repositioned during pasting and has excellent workability that can be extracted according to the topsheet, contributing to improved productivity and reduced processing costs.

FIG. 7 is an explanatory diagram for explaining the structure of another double-sided tape. Conventionally, a double-sided tape uses an acrylic pressure-sensitive adhesive as a base material of a rayon-based nonwoven fabric.
Rayon-based nonwoven fabric does not melt and soften even when heated,
Therefore, even in the re-melting process at the time of recycling (regeneration), the nonwoven fabric may remain as a foreign substance in the recycled component without being uniformly melted and decomposed. When such a phenomenon occurs, the value of the recycled component is reduced, and the economical efficiency of plastic recycling is impaired.

In the double-sided tape shown in FIG. 7, the same ABS resin as the component material (remote control device) is used for the base material, and a special adhesive compatible with the ABS is applied to both surfaces thereof. In FIG. 7, an ABS resin is used as the base material, but a PS (polyethylene) resin may be used.
