Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pet toilet insole sheet used for treating excrement of a pet kept indoors or the like. More specifically, the present invention relates to a pet toilet insole sheet which prevents contamination of a pet toilet container and is easy to use.

[0002]

2. Description of the Related Art Pet toilets are used to treat excrement of pets such as cats kept at home. For example, pet toilets are used by laying small pieces of so-called cat litter or newspaper in the form of small boxes in a small box-shaped container. When the pet excretes in the container, the excrement is absorbed or dammed by the objects laid in the container. There are various types of objects to be laid in the container, depending on the difference in absorption power, the presence or absence of the property of solidifying like a dumpling, and the like. In addition, when this cat litter is used for a toilet of a cat or the like, it also has a role of satisfying the physiological desire of so-called “sanding”. After excreting cats, it is customary to bury sand in the excreta with feet. This is “sanding”.

[0003]

However, when cat litter or the like is used, it takes time and effort to discard the pet after the pet has excreted. If the excrement is not completely absorbed or dammed by cat litter or the like, the container may be contaminated with the excrement. Furthermore, when cat sand is used, the sand and the surroundings may become dirty with the sand.

[0004] It is an object of the present invention to provide a pet toilet insole sheet which can be easily used and discarded, and can prevent the pet toilet container from being soiled. Another object of the present invention is to provide an insole sheet for pet toilets that can satisfy the physiological needs of cats and the like after sand excretion.

[0005]

SUMMARY OF THE INVENTION The above-mentioned conventional objects and objects are to provide a laminated sheet in which a non-woven fabric layer and a liquid-impermeable sheet layer are superimposed, and a three-dimensional shape obtained by folding the non-woven fabric layer inward. It is deformable into a shape, and has a quadrilateral bottom surface in this three-dimensional shape, four side surfaces surrounding the four sides, and an opening, and a box body in which the nonwoven fabric layer is an inner surface is formed. Achieved by a pet toilet insole sheet.

[0006] The insole sheet for pet toilets of the present invention is
Use by laying inside the pet toilet container. Inside the insole sheet, small pieces of absorbent material such as cat litter and newspaper can be put and used. When the pet excretes, even if these absorbent pieces cannot absorb the excrement, the outside of the insole sheet is a liquid-impermeable sheet layer,
It does not leak to the outside of the insole sheet. Also,
Because the insole sheet is a box when it has a three-dimensional shape,
The excrement scattered on the side of the toilet container does not leak out. Therefore, the toilet container does not become dirty. Further, when the insole sheet is discarded at the time of cleaning, the small pieces of absorbent put inside the insole sheet can be discarded together, so that the toilet can be easily cleaned. In addition, you may put cat sand, such as bentonite, in this box and use it. In addition, it is flat when sold or stored, and can be folded. Therefore, it can be handled compactly.

[0007] The laminated sheet forming the insole sheet for a pet toilet of the present invention is rectangular, and in the planar shape,
Both sides of the laminated sheet are bent toward the center line of the sheet, and have a flat shape in which the inner surfaces of the sheets are joined to each other at both ends of the both sides, by expanding the both sides outward from the center line. Preferably, the side portions and the joined end portions form the four side surfaces to form a box. When the insole sheet is formed in this manner, a box can be formed by a simple operation of expanding both sides outward with respect to the center line. Therefore, anyone can easily lay it in the toilet container. In addition, since it can be folded along the fold when discarded, it can be discarded easily and as small trash.

It is preferable that the pet insole sheet for a toilet of the present invention, when it has a planar shape, contains a plurality of absorptive materials in advance inside the box. If the insole sheet is stored in advance, it can be used immediately if the insole sheet is expanded at the time of use without putting a new piece of the absorber inside the insole sheet. In addition, it is possible to satisfy the so-called "sanding" physiological needs of cats and the like after excretion.

It is a perspective view showing a state. FIG. 3 is a perspective view showing a state in which the pet insole sheet for a toilet of the present invention is in the form of a box.

An example of the method for forming the pet toilet insole sheet of the present invention will be described below. Laminated sheet 10 forming the insole sheet for pet toilet of the present invention shown in FIG.
Is formed in a rectangular or square shape by superimposing the nonwoven fabric layer 1 on the liquid impermeable sheet layer 2. A line crossing substantially the center of the laminated sheet 10 is referred to as a center line 3. This laminated sheet 1
0 are bent toward the center line 3 at the bending lines 5a and 5b. At this time, the nonwoven fabric layer 1 is bent so as to face inward. FIG. 2A shows the planar laminated sheet 10 thus obtained.

A laminated sheet 1 having a planar shape shown in FIG.
0 is both ends 6a of the bent both sides 4a, 4b,
The inner surfaces of the laminated sheets 10 overlapping at 6a, 6b, 6b are joined together to form joints 7a, 7b, 7c, 7d.
Is formed. Further, as shown in FIG. 2A, joining lines 8a, 8b, 8c, 8d extending obliquely from the bending lines 5a, 5b toward the end portions 3a, 3b of the center line 3 are formed. In addition, both ends 6a, 6 of both sides 4a, 4b
a, 6b, 6b, bending lines 5a, 5b, bonding portions 7a, 7b, 7c, 7d, and bonding lines 8 extending obliquely
The inner surfaces of the laminated sheet 10 may be joined to each other over the entire inner surface of the triangular region surrounded by a, 8b, 8c, and 8d.

At the time of sale or storage, the planar shape shown in FIG. 2A is further folded at the folding lines 9a and 9b to become a substantially square as shown in FIG. 2B. In use, it is developed from the state of FIG. 2 (A) to the state of FIG. 2 (B), and the sides 4a, 4b are expanded in the direction of arrow (i), that is, the sides 4a, 4b are centered. By spreading outward from 3, a three-dimensional box as shown in FIG. 3 is formed. At this time, diagonal joining lines 8a, 8b, 8 are formed at both ends 6a, 6b of the bent portion.
When c and 8d are formed, a box is easily formed when the box is expanded in the direction of the arrow (i). That is, when the both sides 4a, 4b are spread in the direction of the arrow (i), the spread is stopped by the oblique joining lines 8a, 8b, 8c, 8d, and the both ends 4a, 4b and the joined both ends 6a, 6b
This forms the four sides of the box. Therefore, a well-shaped box is easily formed. The pet toilet insole sheet 20 having a three-dimensional shape has a bottom surface 12 and side surfaces 11a, 11b surrounding four sides thereof, as shown in FIG.
11c and 11d, and a box having an opening at the top. In the insole sheet 20, the nonwoven fabric layer 1 is located on the inner side 13, and the liquid-impermeable sheet layer 2 is located on the outer side 14. Also, a large number of nonwoven fabric layers may be stacked only on the bottom surface 12 of the insole sheet 20.

FIG. 4 is a perspective view showing a use form of the insole sheet for pet toilet of the present invention. As shown in FIG. 4, the pet toilet insole sheet 20 of the present invention is used, for example, laid inside a box-shaped toilet container 30. In addition, it is preferable that the insole sheet 20 is used in a state in which a plurality of absorptive small pieces 31 are put in order to absorb excrement. This also fulfills the cat's physiological need for “sanding”. The pet toilet insole sheet 20 of the present invention has a plurality of small pieces 31 previously stored as an absorptive material inside the insole sheet 20 in a sectional view taken along the line BB in FIG. As shown in FIG. 5 (B), it is preferable to fold and sell. If the small piece 31 is stored in advance, it can be used immediately if the insole sheet is expanded at the time of use, without newly adding a small piece of the absorber inside the insole sheet 20. Even in such a form, the size is compact and it is convenient to carry.

When the pet excretes on the insole sheet 20, the excretion is absorbed by the small pieces 31 of the plurality of absorbers on the inside 13. In addition, even if there is excrement that could not be absorbed or excreta scattered sideways, the insole sheet 20 of the present invention does not leak into the toilet container 30. Therefore, the toilet container 30 does not become dirty. Further, when cleaning the toilet, the plurality of absorbers on the inner side 13 can be discarded together.

Further, as shown in FIG. 4, a joining means 32 for joining the insole sheet 20 to the toilet container 30 may be provided on the opening side of the side surface of the insole sheet 20 of the present invention. preferable. By providing the joining means 32, the insole sheet 20 can be reliably held in the toilet container 30. The joining means 32 is preferably provided on the side surfaces 11b and 11d of the insole sheet shown in FIG. Further, it may be provided on all the side surfaces 11a, 11b, 11c and 11d. The joining means 13 is, for example, an adhesive tape. The size of one joining means depends on its joining strength (adhesive strength), but it is 2cm ×
About 2 cm is sufficient.

The nonwoven fabric layer 1 comprises a wet nonwoven fabric, a dry nonwoven fabric,
Any material such as spunlace, spunbond, melt blown, and needle punch can be used. Of these, spunlace nonwoven fabrics are preferred because of their strength. The spunlaced nonwoven fabric is formed from rayon or the like having water absorbency. Alternatively, it is formed from a water-absorbing fiber such as rayon fiber and the synthetic fiber. When a nonwoven fabric made of a water-absorbing fiber is used, the excrement can be absorbed by the nonwoven fabric in a small amount when it scatters. Further, in order to give a hygienic impression to a person, a non-woven fabric colored in blue or the like can be used.

The liquid-impervious sheet layer 2 may be any material as long as it does not allow liquid to permeate, and is, for example, a polyethylene (PE) film or a vinyl sheet.

The nonwoven fabric layer 1 and the liquid-impermeable sheet layer 2
Form a laminated sheet 10 one by one or a plurality of sheets. The respective layers constituting the laminated sheet 10 are entirely or partially joined by an adhesive or the like. The absorbent material laid in the insole sheet is generally assumed to have a water absorbing property, for example, polyacrylic acid. System, polyvinyl alcohol system, maleic anhydride and other addition polymers, polyether system, polymer represented by condensation system, starch system,
Highly water-absorbing resins such as cellulose and other polysaccharides, proteins such as collagen, pulp, and nonwoven fabrics containing absorbent fibers can be used.

These absorbent materials are cats that are "sandy"
Is preferably lightly joined to the bottom surface 12 of the insole sheet 20 so that the cat can be satisfied when performing the operation. For example, when the absorbent material is made of pulp, tissue, olefin fiber, hydrophilically treated fiber, rayon, etc., after spraying water on these materials, pressing the insole sheet by pressing Can be lightly joined. However, it is preferable that the joints are loosened when they are scratched by the feet of a cat or the like when "sanding".

The absorbent material comprises a plurality of absorbent particles 3
When composed of 1, the small piece 31 is preferably formed of a nonwoven fabric. This is because it is light and has absorbability. When the small piece 31 of the absorber is formed of a nonwoven fabric, for example, one piece having a size of a square having a side of 1 to 2 cm is used. The number of sheets stored in one insole sheet 20 depends on the type and thickness of the nonwoven fabric, but it is preferable that about 100 pieces be stored.

In addition, bentonite used for cat litter or the like may be spread over the entire surface of the bottom surface 12 of the insole sheet 20 and solidified in advance. It is preferable that the degree of hardening is such that the cat or the like easily loosens when performing "sanding".

The pet toilet insole sheet 20 of the present invention thus obtained, in which the small pieces 31 of the absorbent material are stored in advance, can be spread in a toilet container and used as it is. It can fully fulfill its function as a pet toilet.

Insole sheet 20 for pet toilet of the present invention
Is not limited to the method described above. The laminated sheet may be bent at several places so that the insole sheet forms a box to form a box. Alternatively, for example, a box may be formed by making a cut in the laminated sheet and joining the cut portion. Further, the laminated sheet forming the insole sheet is not limited to a square or a rectangle, and a box may be formed using a circular, rhombic, or other shape. However, the use of the method described in detail above simplifies manufacturing and reduces costs.

[0024]

According to the pet toilet insole sheet of the present invention which is used by being laid inside the toilet container described in detail above, the excrement leaks out when the pet excretes, and Does not stain containers. Further, since the insole sheet has a side surface, even if excrement is scattered, the container is not stained. Furthermore, when cleaning the toilet, when the insole sheet is discarded, small pieces of the plurality of absorbers placed inside the insole sheet can also be discarded together, so that cleaning is easy. Moreover, since the toilet insole sheet of the present invention is formed from a laminated sheet, it becomes thin and compact when folded. Therefore, it takes no space for storage and is convenient for carrying.

In addition, the pet toilet insole sheet of the present invention can be easily and conveniently used by putting an absorbent material in advance and spreading the toilet container for use immediately. Also, if this absorbent material is lightly bonded to the insole sheet, it is possible to further satisfy the physiological desires of cats and the like for "sanding".
