[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet seat, and more particularly to a toilet seat for receiving urine drops when the toilet is used.

[0002]

2. Description of the Related Art Currently, cloth toilet mats and non-woven toilet seat covers are used to prevent splashing of urine drops and the like when using a toilet. That is, these are installed in the toilet or around the toilet, and when they become dirty due to use, they are washed and repeatedly used, or they are simply discarded in the trash box.

[0003]

The conventional products as described above are more dirty and have a bad odor than they would have been if they actually tried to use them. Therefore, even if it is washed and reused, it cannot be washed with other laundry, which is troublesome. Further, even if it is discarded in the trash box, it has a problem that it has a bad odor and needs to be sealed, which makes the handling troublesome.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a toilet seat that can be maintained in a stable installed state and can be disposed of after use in the toilet.

[0005]

In order to achieve the above object, the invention according to claim 1 is a toilet sheet, which is formed by mixing a water-absorbent fiber and a water-soluble fiber. And a plurality of water-resistant pressure-sensitive adhesives formed on one surface of the water-absorbent sheet so as to be scattered in an island shape.

According to this structure, the pressure-sensitive adhesive stabilizes the installed state at the time of use, and when immersed in water, the water-soluble fiber dissolves and the water-absorbent sheet decomposes between the positions where the pressure-sensitive adhesive is formed.

The invention according to claim 2 is a toilet seat, which is formed of a water-absorbent and water-soluble paper-made water-absorbent sheet, and is formed so as to be scattered like islands on one surface of the water-absorbent sheet, And a plurality of adhesives having water resistance.

According to this structure, the pressure-sensitive adhesive stabilizes the installed state at the time of use, and when immersed in water, the water-absorbent sheet dissolves and the water-absorbent sheet decomposes between the positions where the pressure-sensitive adhesive is formed.

According to a third aspect of the present invention, in the structure of the first or second aspect of the invention, a plurality of water-resistant sheets are formed on the other surface of the water-absorbent sheet so as to be independent of each other. The printed pattern is further provided.

According to this structure, the print pattern gives a design change to the appearance and does not hinder the decomposition of the water absorbing sheet when immersed in water.

According to a fourth aspect of the invention, in the structure of the invention according to any one of the first to third aspects, each of the pressure-sensitive adhesives has a disc shape and is arranged in a zigzag pattern or a lattice pattern. It is something.

[0012]

As described above, according to the first aspect of the present invention, the installation state during use is stable, and since the water absorbing sheet is decomposed by water, the water absorbing sheet can be flushed to the toilet and the treatment after use can be performed. It will be easy.

According to the second aspect of the present invention, the installed state is stable, and since the water absorbing sheet is decomposed by water, the water absorbing sheet can be flushed to the toilet and the treatment after use becomes easy.

According to the third aspect of the present invention, a printed pattern that changes appearance can be formed, and decomposition of the water absorbing sheet is not hindered, so that the quality of the toilet seat is further improved.

[0016]

FIG. 1 is a view showing the external shape of a toilet seat according to a first embodiment of the present invention,
Part (1) is a plan view, part (2) is a rear view thereof, and FIG. 2 is an enlarged cross-sectional view showing the cross-sectional structure of the toilet seat of FIG. 1.

With reference to these figures, the toilet seat 1
1 is composed of a sheet material having a boomerang shape. The sheet material is mainly composed of the water absorbing sheet 13, the printed pattern 14 is formed on the surface thereof, and the adhesive 16 is formed on the lower surface thereof.

The water-absorbent sheet 13 is made of a non-woven fabric prepared by mixing ray-absorbent rayon fiber (95%) with polyvinyl alcohol (PVA) fiber (5%) as a binder, and the basis weight is 70 g / m ² . .
Note that pulp fibers may be used instead of the rayon fibers forming the water absorbent sheet 13. In addition, the water absorbing sheet is made of PVA
Although it may be composed only of water-soluble fibers such as fibers, this is not so preferable because even if a small amount of water is dropped, the whole is easily dissolved.

As the adhesive 16, an acrylic or urethane water-resistant adhesive is used. The adhesive 16 is not applied to the entire lower surface of the water absorbent sheet 13,
Each is applied so as to be scattered in an island shape. That is, the pressure-sensitive adhesive 16 is formed on the lower surface of the water-absorbent sheet 13 so that a continuous portion to which the pressure-sensitive adhesive 16 is not necessarily applied remains. Further, it is preferable that the application area of each adhesive 16 is made as small as possible.

In this embodiment, (2) in FIG.
Each of the adhesives 16 has a diameter of 5 mm, as shown in FIG.
The water-absorbent sheet 13 is applied in a zigzag shape as a whole so that it has a circular disk shape and three adjacent adhesives 16 are located at the vertices of an equilateral triangle. The distance A between the adjacent adhesives 16 is 20 mm.

A printed pattern 14 is formed on the surface of the water absorbent sheet 13, and the printed pattern 14 has water resistance. This is to prevent the printed pattern 14 from bleeding when urine or the like drops on the surface of the water absorbent sheet 13. As described above, since the printed pattern 14 is not water-soluble, each of the printed patterns 14 is formed so as not to be continuous on the surface of the water absorbent sheet 13.
That is, the printed pattern 14 is also formed in the same manner as the pressure-sensitive adhesive 16 so that the portion where the printed pattern 14 is not formed is continuous on the surface of the water absorbent sheet 13.

FIG. 3 is a perspective view showing a use state of the toilet seat shown in FIGS.

Referring to the drawing, the toilet seat 11 is attached to the upper surface of the upper edge portion 19 of the toilet bowl 18 with the adhesive 16 facing downward. And the tip 21 of the toilet seat 11
Bend downward to use. Since the adhesive 16 is scattered on the lower surface of the toilet seat 11 and the back surface of the tip portion 21 in an island shape, the adhesive force attaches the toilet seat 11 to the toilet bowl 18, and Securely retained. Therefore, there is no risk that the toilet seat 11 will be inadvertently moved or turned over with respect to the toilet bowl 18 during use.

When a urine drop or the like is dropped on the toilet seat 11 during use, the absorbent fiber constituting the water absorbent sheet 13 absorbs the water and prevents splashing around. Since the pressure-sensitive adhesive 16 has water resistance, even if moisture such as urine drops reaches the pressure-sensitive adhesive 16 through the water absorbent sheet 13, the pressure-sensitive adhesive effect is not reduced.

The toilet seat shown in FIGS. 1 and 2 is used by being stuck on the upper edge portion 19 of the toilet 18 as shown in FIG. However, the toilet seat is configured as the rectangular seat-shaped toilet seat 23 shown by the phantom line in FIG. 3 with the same cross-sectional configuration shown in FIG. 2, and this is placed on the floor of the toilet near the toilet bowl 18. It is also possible to arrange and use. In this case, the pressure-sensitive adhesive 16 comes into contact with the floor surface, so that careless sliding and curling are prevented and a stable use state is secured.

When the toilet seat 11 becomes dirty due to use, the toilet seat 11 may be peeled off from the toilet 18 and put into the toilet 18 as it is. In this case, since each of the pressure-sensitive adhesives 16 has a small disc shape, the pressure-sensitive adhesive 16 can be easily peeled off, and the adhesive residue on the toilet bowl 18 after the toilet seat 11 is peeled off is prevented. Although the adhesive 16 has water resistance as described above, it is also possible to select a water-soluble adhesive. However, a water-soluble pressure-sensitive adhesive is soluble in even a small amount of water, and may cause adhesive residue when the water-absorbent sheet is peeled off.

Further, since the adhesive 16 is not applied to the entire lower surface of the water absorbent sheet 13 as described above, the water absorbent sheet 1
There is always a portion of the outer edge of No. 3 where the adhesive 16 is not applied. Therefore, from that part, the water absorbing sheet 13
The peeling operation becomes easier by picking. Further, since the pressure sensitive adhesive 16 is evenly arranged on the back surface of the water absorbent sheet 13 in a zigzag manner, the slip prevention effect is stably exhibited.

The used toilet seat 11 put in the toilet 18 absorbs a large amount of water, and the water absorbing sheet 13 of the toilet seat 11 is decomposed.

FIG. 4 is an enlarged sectional view showing a sectional state of the toilet seat in such a state.

Referring to the figure, when the water-absorbent sheet 13 absorbs a large amount of water, the water-soluble PVA fiber as the binder of the water-absorbent sheet 13 is dissolved, and the water-absorbent fibers connected to each other are released. Will be lost.
On the other hand, since the printed pattern 14 and the adhesive 16 each have water resistance, they are not affected by water absorption and the state during formation is maintained. Therefore, even if the PVA fiber is in a melted state, the rayon fiber in the portion where the adhesive 16 and the printed pattern 14 are formed is held to some extent by these.

On the other hand, on the lower surface of the water absorbing sheet 13, the adhesive 1
6 is continuously applied, and similarly, the upper surface of the water absorbent sheet 13 is also continuously provided with no printed pattern 14. Therefore, in the water absorbent sheet 13 in these parts, the rayon fibers are unraveled by melting the PVA fibers in those parts, and decompose at that position. That is, the toilet seat 11 is disassembled into fine pieces as shown in FIG. 4 at the positions where the adhesive 16 and the print pattern 14 are not formed. As a result, the toilet seat 11 put into the toilet 18 can be reliably discharged through the drain pipe.

As described above, since the toilet seat 11 according to the present embodiment is disposed of simply by throwing it into the toilet bowl 18 after use, the disposal is facilitated and the usability is improved.

FIG. 5 is a diagram showing an application pattern of an adhesive used in a toilet seat according to the second embodiment of the present invention.

Referring to the drawing, in this embodiment, each of the adhesives 16 has a diameter of 5 mm as in the previous embodiment.
Although it has a disk shape of about mm, the island-like array is in a grid pattern. That is, the four adjacent adhesives 16 are located at the vertices of a square shape, and the distance B between them is 20 mm. Even when the adhesive 16 is applied in this manner, it is decomposed by being dipped in water as in the previous embodiment, so that it can be put in a toilet bowl. Further, the shape and arrangement of the pressure-sensitive adhesive 16 exerts a stable anti-slip effect and facilitates the peeling of the water-absorbent sheet after use.

Although a nonwoven fabric is used as the water absorbent sheet in the above-mentioned embodiment, the same effect can be obtained by using a paper sheet having water absorbency and water solubility instead of this.

Further, in the above embodiment, the printed pattern is formed on the upper surface of the water absorbing sheet, but this is intended to improve the design of the toilet seat and is not always necessary.

Further, in the above-mentioned embodiment, the water-absorbing fiber and the water-soluble fiber are specified.
It goes without saying that other fibers having these functions may be used.

Further, in the above-mentioned embodiment, the size, shape and arrangement of the pressure-sensitive adhesive are specified, but if the uncoated portion remains, a pressure-sensitive adhesive having a size other than this is adopted. It is also possible.

Further, in the above embodiment, the external shape of the water absorbent sheet for a toilet is specified, but it goes without saying that the same effect can be obtained even if the shape is other than this.
