Technical Field

The present invention relates to a three-dimensional toilet seat and a method for manufacturing the same, which covers the upper part of a toilet seat of a western-style toilet.

Background

Conventionally, covers for covering toilet seats made of synthetic resin have been used to avoid a cool feeling when sitting on the toilet seats directly.

In recent years, a pair of crescent-shaped base fabric covers that are used by being stuck to the surface of a toilet seat have been the mainstream. It is mostly called a "toilet seat sheet". As a method for adhering a toilet seat sheet to a toilet seat surface, a method of laminating a self-adhesive resin on a base cloth is generally employed (for example, Japanese patent laid-open No. 2002-233476). Although the toilet seat sheet has advantages such as easy cleaning and easy installation, the flat shape makes it impossible to avoid the situation where a human body directly contacts the toilet seat at the edge of the sheet, and thus the demand cannot be sufficiently satisfied.

In order to solve this problem, the present applicant proposed a new configuration of a toilet seat sheet (japanese patent application laid-open No. 2015-131073) and named "toilet seat cushion" having a sufficient size and shape to cover the range of contact of the thighs with the toilet seat and to such an extent that the action of the washing nozzle is not hindered.

Detailed Description

Hereinafter, embodiments of the present invention will be described based on the drawings.

As shown in fig. 1, the toilet seat 1 is formed as a pair in a bilaterally symmetrical manner, is used by being mounted on a toilet seat 5 at the upper end of a toilet bowl 4, and is disposed so as not to interfere with the operation of a cleaning nozzle (not shown).

As shown in fig. 2 to 5, the toilet seat 1 includes a modified crescent-shaped main body 2 and a fixing portion 3 to be fitted to the toilet seat. As is clear from the respective drawings of fig. 2, the toilet seat 1 is three-dimensional, and is mounted on the toilet seat 5 so as to cover the toilet seat 5 along the three-dimensional shape of the toilet seat 5.

As shown in FIG. 6, the size of the body 2 is 380mm to 450mm in H, 170mm to 210mm in W, 100mm to 140mm in W1, 110mm to 140mm in W2, and 100mm to 130mm in W3 when measured in a planar manner. Here, H is a longitudinal length of the toilet seat 1, W is a lateral length of the toilet seat 1, W1 is a width-directional length of the toilet seat 1 at a point a 100mm forward from a 0 point of the toilet seat, W2 is a width-directional length of the toilet seat 1 at a point b 200mm forward from a 0 point of the toilet seat, W3 is a width-directional length of the toilet seat 1 at a point c shifted 40mm in parallel from a center line of the toilet seat, and 0 is a rear side where the center line of the toilet seat intersects with a center opening of the toilet seat. The size is a sufficient size and shape to cover at least a range where thighs contact the toilet seat 5 among various toilet seats and equivalents thereof sold by toilet seat manufacturers in the past or at the time of this application. The basis thereof is described in Japanese patent laid-open Nos. 2015-131073 by the applicant in the specifications [0009] to [0014 ].

On the back surface of the main body 2, 2 rubber tapes as the antiskid fixing portions 3 shown in fig. 2 (f), 4, and 5 are provided. The fixing portion 3 includes, in order from the toilet seat 1 side toward the outside: adhesive layer 31, base fabric layer 32, absorbent layer 33, and release paper layer 34.

As shown in fig. 5, the center portion 35 of the fixing portion 3 is an unfixed portion that is bonded to the toilet seat main body 2 without an adhesive layer. This is to cope with the case where the shapes of toilet seats manufactured by a plurality of toilet seat manufacturers are subtly different. That is, to avoid the following: when the center portion 35 is brought into close contact with the toilet seat main body 2 via the adhesive layer, the adhesive layer is suitable for some manufacturers, but the adhesive layer is poor in products of other manufacturers, and the suction surface cannot be secured, so that a sufficient fixing force cannot be obtained.

The three-dimensional toilet seat 1 is manufactured as follows.

First, as shown in fig. 7 (a), the sponge layer 7 is attached to the top sheet 6, and then, as shown in fig. 7 (b), the nonwoven fabric layer 8 is attached.

Since the cover cloth 6 of the main body 2 is a portion directly contacting the human body, it is preferable to use a fleece material or a pleated material so as not to give a sense of discomfort. In fig. 3, reference numeral 61 denotes a backing layer of the cover cloth 6.

As the sponge of the sponge layer 7, for example, polyurethane sponge, polyethylene sponge, chloroprene rubber, or the like can be used. The thickness of the sponge layer 7 is preferably about 1 to 10 mm.

The nonwoven fabric layer 8 is formed by blending a nonwoven fabric (for example, polyester) with hot-melt cotton (for example, raw cotton for low-temperature thermal bonding containing low-melting polyethylene as a sheath component) and punching the same together with a PP (polypropylene) sheet (not shown). The blending ratio of the non-woven fabric to the hot melt cotton is 30-50 wt%: 70 to 50 wt%. Most preferably, the blend ratio is 50: 50 wt.% and the weight per unit area of the hot melt cotton is about 400g/m²。

Next, punching is performed at a position shown by a two-dot chain line in fig. 7 (b), and a planar material 9 as shown in fig. 8 (a) is obtained. The planar material 9 is applied with a trim 21 as shown in fig. 8 (b) and is thermoformed in accordance with a mold (not shown) having a shape of a toilet seat. The mold used in this case is synthesized by converting 3D data of toilet seats of a plurality of toilet seat manufacturers by industrial X-ray CT scanning. The heating is preferably performed under the condition that the nonwoven fabric layer 8 becomes a three-dimensional molded product, and is preferably performed at 100 to 160 ℃, more preferably 130 to 150 ℃, for 30 seconds to 3 minutes, and even more preferably 1 to 2 minutes. Most preferably, it is carried out at about 150 ℃ for about 1 minute.

Thus, a three-dimensional toilet seat as shown in fig. 8 (c) can be obtained. After that, the fixing portion 3 of the back surface as described above is attached to complete the toilet seat 1.

It is found by experiments that the toilet seat of this embodiment can endure about 50 times of washing, and maintain the three-dimensional shape without being shrunk. Further, since the mounting tape is not used, cost reduction can be achieved.
