BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shampoo-bowl cushion, which is detachably installed on the peripheral portion of a shampoo-bowl mainly used for washing hair in beauty salons and barbershops, and a manufacturing method thereof.

[0002]

2. Description of the Related Art When washing hair at a beauty salon or barber shop,
A method is widely used in which the person to be washed is placed in a posture of lying on his back and the hair is washed with the head protruding above the shampoo bowl. When this hair washing method is adopted, the back neck of the person to be washed is supported by the front edge of the shamp-bowl, but if the back neck is placed directly on the edge of the shamp-bowl, Felt pressure on the back of the neck and shampooed
I feel uncomfortable with the cold bowl. Furthermore, since the shampoo bowl is made of a hard material, it does not adhere well to the back neck, and water or shampoo does not come into contact with the back neck and shampoo during hair washing.
There is a risk of leakage from the contact area with the bowl wire and scattering.

For this reason, a method has been adopted in which a cushioning member such as a towel is interposed between the shampoo bowl and the back neck of the person to be washed. However, in this method, a cushioning member such as a towel gets wet with water, which causes various problems. For this reason, the inventor of the present invention covers the sponge body having elasticity first with a sheet that blocks the infiltration of liquid, and attaches and detaches a shampoo bowl of various shapes in which a mounting strip and a suction cup are arranged. We have developed a cushion material for a shampoo-bowl that can be attached (Shokaihei 2-119102). Further, the inventors of the present invention arranged a flexible synthetic resin cylinder filled with and sealed with a gel-like material in the longitudinal direction in the central portion of the upper surface of a flexible synthetic resin sheet having an appropriate shape. We proposed a cushion material for shampoo bowls in which a plurality of suction cups are attached to the peripheral portion of the lower surface of the grate (Japanese Patent Application No. 3-41804).

[0004]

However, the above-mentioned synthetic resin cylindrical body filled with a gel material and sealed is excellent as a cushion for a shamp-bowl, but when this is attached to the shamp-bowl, it is in the center. There is a drawback that wrinkles are formed in the vicinity of the portion, a crack is formed at the wrinkle portion and is damaged from this portion, and water stains are accumulated on the wrinkle portion to give a feeling of uncleanness. The present invention further improves the cushioning material for a shampoo bowl, which is filled and sealed with the gel-like material, and when the person to be washed puts his / her back neck, the neck is stably held thereafter, and the person to be washed does not An object of the present invention is to provide a cushion for a shampoo bowl which does not give a pleasant feeling, and therefore can be comfortably washed by a person to be washed, is hard to be soiled, and has good durability.

[0005]

The inventor of the present invention has found that a shampoo
As a result of various studies as a cushioning material for a bowl cushion, the inventors have found that a saddle-shaped base to which a synthetic resin bag filled and sealed with a gel-like material is adhered is extremely suitable, and completed the present invention.

That is, the present invention provides a cushion for a shamp-bowl in which a flexible synthetic resin bag filled with a gel material and sealed is fixed to the upper surface of a saddle-shaped substrate, and a method for manufacturing the cushion.

The present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view of a saddle type base according to the present invention. The lower surface "a" of the saddle type base body 1 forms a concave portion, and is a portion to be fitted and fixed to the edge of the shamp-bowl. This fixing needs to be able to be firmly fixed and to be easily attached to and removed from the edge of the shamp-bowl, so that the saddle type base body 1 is preferably flexible. A synthetic resin such as polyvinyl chloride or polyethylene is used as a material forming the saddle type base 1. In addition, the b portion of the saddle type base body 1 is a portion where the person to be washed puts his / her back neck, and a recess is formed. In the present invention, a flexible synthetic resin bag in which a gel-like material is filled and sealed is fixed to the upper surface c of the saddle type base 1. The upper surface c of the saddle type substrate is preferably covered with the synthetic resin bag over the entire surface.

This flexible synthetic resin bag is made of a sheet of a flexible synthetic resin such as a polyolefin resin such as polyethylene or polypropylene, a polyvinyl chloride resin, an ethylene-vinyl acetate copolymer resin or the like. This bag is made of two soft synthetic resin sheets of a size that matches the upper surface of the saddle type base.
It is made by stacking layers, adhering the periphery, and injecting a gel-like material into it to fill it. The gel-like material is a water-soluble polymer substance such as carboxymethyl cellulose, polyvinyl alcohol, polyacrylic acid-based polymer or the like, which is gelled by adding water to a water-absorbent polymer substance, or silicone gel. Is. At this time, the polymer substance powder may be placed in a flexible synthetic resin bag, and then water may be injected to form a gel-like material in the bag. It is preferable that the bag made of synthetic resin has a plurality of chambers because the gel body will not be biased when the back neck is placed.

Further, in order to fix a flexible synthetic resin bag filled and sealed with a gel-like material to a saddle type substrate, the periphery of the synthetic resin bag is adhered to the saddle type substrate with an adhesive or stitched. To do.
FIG. 2 is a front view of a cushion for a shampoo bowl of the present invention in which a flexible synthetic resin bag in which a gel-like material is filled and sealed is fixed to a saddle type base body, and FIG. 3 is a side view thereof. Reference numeral 1 is a saddle type base, 2 is a flexible synthetic resin bag in which a gel-like material is filled and sealed, and 3 is a fixing portion for fixing the periphery of the synthetic resin bag to the periphery of the saddle type base. In addition, a frame-shaped step that protrudes around the upper surface of the saddle type base is provided, and a flexible synthetic resin bag filled and sealed with a gel-like material is fitted into the step, and the protruding peripheral part of the saddle type base and the synthetic resin bag periphery are fitted. When the parts are fixed to each other, the synthetic resin bag can be smoothly fixed to the saddle type base body.

By the way, when the gel-filled synthetic resin bag is fixed to the saddle-shaped substrate, the flat gel-filled synthetic resin bag is fixed according to the curved surface of the saddle-shaped substrate. Wrinkles are likely to occur on the surface of the synthetic resin bag. When this wrinkle occurs, it causes discomfort when the back neck is applied, and water stains adhere to the part, which causes a feeling of uncleanness. Therefore,
It is preferable to prevent wrinkles on the surface of the synthetic resin bag. In order to prevent such wrinkles, it is preferable to adopt the following method for the shape of the bag made of synthetic resin filled with gel and for the fixing portion of the saddle type substrate.

First, a preferred method for producing a synthetic resin bag is as follows. That is, two sheets of semi-circular to semi-elliptical soft synthetic resin sheets are superposed, the inner sides of the straight sides of the superposed sheets are linearly shaped, and the central portion is arcuately shaped. The sheets are adhered in a line shape, and the sheets made of soft synthetic resin having the same shape as the above-mentioned semicircle to semi-elliptical shape are respectively overlapped on the upper surface side and the lower surface side of the adhered sheets, and the upper two sheets are attached. -Adhere the sheets at the periphery to form the upper bag, and similarly attach the two sheets on the lower side at the periphery 7 to make the lower bags, and make a gel in each bag. A flexible synthetic resin bag in which a gel-like material is filled and sealed is manufactured.

FIG. 4 illustrates the manufacturing method.
As shown in the plan view of FIG. 4 (i), four sheets of soft synthetic resin sheets having a semicircular to semielliptical shape are prepared. Take two of them and stack them. The inner ends of the straight side 4 of the superposed sheets are welded into a linear shape 5 and the central portion is arcuately 6 to form a linear adhesive portion (see FIG. 4 (ii)). , (A) are plan views, and (b) are schematic sectional views. ]. The remaining two sheets of the soft synthetic resin are overlaid on the upper surface side and the lower surface side of the adhered sheet, respectively, and the upper two sheets are adhered at the periphery 7 thereof. A bag is made, and the lower two sheets are similarly bonded at the periphery 7 to make a lower bag [see FIG. 4 (iii), (a) is a plan view, (b)] Is a schematic sectional view]. When adhering each peripheral portion, an unadhered portion is provided in a part of each peripheral portion. Then, an appropriate amount of gel-like material is injected from this unbonded portion, and then this unbonded portion is bonded to manufacture a gel-filled synthetic resin bag. The gel-filled synthetic resin bag thus obtained is divided into two chambers, the upper portion and the lower portion, and the gel-like material is filled and sealed in each chamber. Expand the space between the upper part and the lower part, and then bend inward at a right angle to this, and the lower surface will be made of a gel-filled synthetic resin that has a curved surface that is almost the same as the upper surface of the saddle type substrate. It becomes a bag.

The gel-like material injected is placed on a saddle type substrate, and the periphery thereof is fixed to the saddle type substrate. At this time, as described above, if a frame-shaped step is provided so that the periphery of the saddle type base body is fitted to the outer periphery of the gel-filled synthetic resin bag, the fixing can be smoothly performed, and the gel-filled material can be filled. Distortion due to sticking does not occur in the synthetic resin bag. FIG. 5 is a front view of the shampoo-bowl cushion manufactured as described above. FIG. 6 is a sectional view taken along the line AA. Reference numeral 1 is a saddle type substrate, and 2 is a bag made of a synthetic resin filled with a gel material. Reference numeral 3 denotes a fixing portion that fixes the periphery of the synthetic resin bag to the periphery of the saddle type base body. Reference numeral 6 denotes a portion in which the upper bag and the lower bag are bonded to each other in a circular arc shape at the joint. Reference numeral 8 denotes a frame-shaped step protruding around the saddle type base body. The gel-filled synthetic resin bag 2 has entered the step 8. Reference numeral 9 denotes a joint portion between the saddle type base body and the outer peripheral portion of the gel-like material-filled synthetic resin bag.

In the cushion for shamp-bowl of the present invention, since the cushion material made of synthetic resin is filled with a gel material, the temperature of the cushion for shamp-bowl can be increased by heating or cooling. Since it is retained for a long time by the gel-like material, if the temperature is adjusted according to the climate and the temperature and then it is attached to the shamp-bowl, the person to be washed can comfortably receive the hair.

[0015]

The shampoo-bowl cushion of the present invention has a saddle-shaped base, so that the shampoo-bowl front edge of the shampoo-bowl, that is, the part to which the back neck of the person to be washed contacts, when the hair is washed.
It is possible to easily fix the saddle type base body by inserting the recessed portion. In addition, since the cushion is made of a gel-filled synthetic resin bag, it feels good on the skin and has excellent cushioning properties. Also, since this gel-filled synthetic resin bag is fixed on the saddle-shaped substrate, it has excellent retention of the back neck of the person to be washed and good adhesion. Further, it can be used in an appropriate temperature state by utilizing the heat retaining property of the gel-like substance. Therefore, the person to be washed can comfortably receive the hair. Then, as described above, the sheet 4 made of the soft synthetic resin having a semicircular or semielliptical shape.
Wrinkles are formed on the surface of the gel-filled synthetic resin bag by manufacturing a gel-filled synthetic resin bag using a single sheet and fixing it to a saddle-shaped substrate with a frame-shaped stepped projecting periphery. Therefore, it is possible to produce a cushion for a shamp-bowl that does not occur, and therefore has a particularly good texture and does not accumulate water scale and has an excellent appearance.
