Abstract

PROBLEM TO BE SOLVED: To dissolve the problems that time and labor are required since it is required to discard sand inside a container at every constant interval and wash the container and it is not sanitary since excreta stick to hands in a toilet for a pet inside home. SOLUTION: A non-liquid-transmissive sheet 4 is spread in the container 3 so as to entirely cover the inner surface of the recessed part 3a of the container 3 and a cover member 5 is put on to the opening edge part 3b of the container 3. Then, an excreta processing material 2 is put in the recessed part 3a of the container 3. When the pet discharges urine and feces from the top of the excreta processing material 2, since the inner surface of the recessed part 3a of the container 3 is covered with the non-liquid-transmissive sheet 4, the sticking of the excreta to the container 3 is prevented. At the time of cleaning this toilet for the pet, only the excreta processing material 2 is wrapped with the non-liquid-transmissive sheet 4 and thrown away, the time and labor for washing the container 3 are omitted and cleaning is performed without staining the hands. Also, since the sheet 4 is covered with the cover member 5, the sheet is not torn with the nails of a cat or the like.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet for pets such as cats and dogs kept indoors, and more particularly to a toilet for pets that can clean the toilet cleanly and easily without soiling hands.

[0002]

2. Description of the Related Art As a pet toilet for cats and dogs kept indoors to urinate and defecate indoors, so-called cat litter and other granular excrement disposal materials are placed in plastic containers. Things are used. FIG. 4 is a perspective view showing the whole of such a pet toilet. As shown in FIG. 4, the plastic container 1 has an open upper surface, and has a concave portion 1a at the center thereof. An appropriate amount of the excrement disposal material 2 is placed in the concave portion 1a. As the excrement treatment material 2, mineral zeolite, river sand, bentonite which solidifies when water is absorbed, urine, and the like, cellulose granules formed by solidifying pulverized pulp and the like to form columnar or spherical particles are generally used. Have been. A pet such as a cat enters the concave portion 1a of the container 1 across the peripheral portion 1b of the container and excretes urine and feces from above the excrement disposal material 2. The owner removes the excrement disposal material 2 contaminated with urine or stool from the container 1 by scooping the excrement disposal material together with the stool with a scoop or the like, and replenishes the same amount of new excrement disposal material as the removed excrement disposal material. ing.

[0003] The zeolite and river sand used as the excrement disposal material 2 do not absorb urine, and bentonite and cellulose granules absorb urine to some extent but cannot completely absorb it. For this reason, urine enters the bottom of the container through the excrement disposal material. Also, when a cat or the like stirs the excrement disposal material 2, the excrement adheres to the cat's leg and touches the container 1 with the urine or stool dirty leg.
Urine and stool easily adhere to the container 1. As described above, since the urine and stool attached to the container cause a bad smell, the owner discards all the excrement disposal materials 2 in the container 1 once every one to two weeks, and disposes of the container 1 After cleaning and drying, it is necessary to keep the toilet clean with fresh waste management material. As described above, since it is necessary to discard all the excrement disposal materials at least once every one or two weeks and clean the toilet container, it is troublesome. In addition, when cleaning the container or disposing of the excrement disposal material, the urine and stool of the pet adhering to the container and the excrement disposal material may get on the hands,
Not hygienic.

[0004]

In order to eliminate the trouble of cleaning such a toilet container, for example, Japanese Patent Application Laid-Open No. 8-172 is disclosed.
Japanese Patent Publication No. 964 discloses an invention relating to a pet toilet in which a paper container containing an excrement disposal material is placed in a central concave portion of the toilet container. In this pet toilet, after a cat excretes urine and stool on the excrement disposal material placed in a paper container, excrement such as stool and excrement disposal material contaminated with excrement are made of paper. Discard the entire container and replace it with a replacement paper container that contains the new excrement disposal material. Therefore, the excrement disposal material can be replaced without soiling the hands, and since the toilet container in which the paper container is placed does not become dirty, the labor for cleaning the toilet container can be omitted. However, if the excrement disposal material is replaced for each paper container every time pet excrement is processed, the amount of trash increases. In addition, the production cost increases because the paper container is produced. Also,
The paper container containing the excrement disposal material is bulky and difficult for the buyer to carry.

An object of the present invention is to solve the above-mentioned conventional problems, and an object of the present invention is to provide a pet toilet that can be cleaned without soiling hands and without trouble.

[0006]

According to the present invention, there is provided a pet toilet, comprising: a container having a recess formed therein as an area for excreting a pet; and a liquid-impervious sheet laid in the recess around the recess. And a cover member fitted to the opening edge so that it can be sandwiched between the opening edge and the excrement disposal material is put on the sheet in the recess. .

As the above-mentioned sheet, it is possible to use a laminated sheet having a liquid absorbing layer on the front side in contact with the excrement disposal material and an impermeable layer on the back side facing the container.

The cover member is shaped to cover an opening edge around the concave portion and an inner wall of the concave portion, and the excrement disposal material is inserted to a position above a lower end portion of the cover member covering the inner wall. It is preferably used.

Further, it is preferable that a projection is provided at a lower end of a portion of the cover member that covers the inner wall so as to extend toward the inner wall of the container and sandwich the sheet with the inner wall.

In the pet toilet of the present invention, a sheet is laid from the bottom surface of the concave portion of the plastic container to the opening edge around the concave portion.

As this sheet, a liquid-impermeable sheet is used, and a granular excrement treating material such as cat sand is put on the liquid-impermeable sheet. The sheet is made of, for example, a polyethylene resin or a polyvinyl alcohol resin and is impermeable to moisture. The liquid-impervious sheet may be placed inside the container as it is, but more preferably, an adhesive seal portion or the like is provided so that the sheet is adhered to the inner surface of the concave portion of the container. Alternatively, it may be attached to the opening edge of the container with an adhesive tape or the like.

A cover member is placed over the liquid-impermeable sheet covering the opening edge of the container. This cover member is made of plastic, etc.
It is not easy to cut. The cover member is fitted to the opening edge of the container, and the peripheral edge of the sheet is fixed between the opening edge of the container and the cover member.

Further, the lower end of a portion of the cover member which covers the outside of the opening edge of the container (the outer surface indicated by reference numeral 5c in FIGS. 1 and 2) is formed so as to wrap around the outside of the opening edge. Alternatively, a buckle or the like may be provided so that the opening edge of the container is sandwiched by the lower end of the outer surface portion 5c, and the cover member may be hooked on the opening edge. In this case, the cover member is securely fitted to the opening edge of the container.

When a domestic pet, such as a cat or a dog, excretes urine or stool from above the excrement disposal material, the urine not absorbed by the excrement disposal material passes through the excrement disposal material to a container. Reaches the bottom of the container and adheres to the bottom of the container. Further, after the pet such as a cat excretes, the excrement disposal material is mixed with the legs, and the dirt adheres to the inner surface of the concave portion of the container. However, since the inner surface of the concave portion of the container is completely covered with the liquid-impermeable sheet, the liquid-impermeable sheet can prevent urine, stool, and the like from adhering to the container.

Further, a cover member made of plastic or the like is placed over the liquid-impermeable sheet on the opening edge of the container, so that the liquid-impermeable sheet is not exposed outside at the opening edge of the container. I have to. For this reason, the liquid-impermeable sheet is not broken even if, for example, the pet puts his / her feet on the opening edge of the container when the pet enters the container, or raises a claw. In addition, since the liquid-impermeable sheet is pressed toward the inner surface of the concave portion of the container by the cover member, the liquid-impermeable sheet can be prevented from floating from the container at the opening edge of the container, and the liquid-impermeable sheet can be prevented. Can be adhered to the container.

The cover member preferably has a shape covering the opening edge of the container and the inner wall of the recess, and further, the excrement disposal material is located above the lower end of the cover member covering the inner wall. It is preferable to increase the height of the cover member so that the cover member can be inserted. When the height dimension of the cover member is increased in this way, the liquid-impermeable sheet is hidden by the excrement disposal material, and the liquid-impermeable sheet does not appear on the outside. Therefore, the liquid-impermeable sheet can be reliably pressed into the concave portion of the container by the cover member, and the liquid-impermeable sheet can be brought into close contact with the inner surface of the container. In addition, the sheet is not broken by a cat or the like.

Further, a projection is formed at the lower end of the cover member that covers the inner wall of the container and extends toward the inner wall, and the sheet is sandwiched between the projection and the inner wall of the container. The adhesion between the liquid-impermeable sheet and the inner wall of the container is enhanced. Further, since the gap between the cover member and the inner wall of the container is closed by the projection, the excrement disposal material is less likely to enter between the cover member and the inner wall of the container. Therefore, it is preferable that the projecting portion has a projecting shape that extends over the entire circumference at the lower end portion of the cover member so as to be able to contact the inner wall of the concave portion of the container over the entire length.

When cleaning the toilet, every time the pet excretes, the excrement disposal material contaminated with excrement is removed and a new excrement disposal material is added. Then, once a week or two weeks, remove the cover member, hold the end of the liquid-impermeable sheet and wrap the excrement disposal material with the liquid-impermeable sheet, and in this state Discard the excrement disposal material. Since the excrement disposal material can be wrapped with the liquid impermeable sheet and discarded, the excrement disposal material does not spill, and the excrement disposal material can be easily disposed of without soiling the hands. Also, since only the liquid-impermeable sheet is discarded together with the excrement disposal material, the amount of dust does not increase so much.

Further, since the inner surface of the concave portion of the container is almost completely covered with the liquid-impermeable sheet, the container is not contaminated with urine, feces, or the like. Therefore, labor for washing the container can be omitted.

The sheet laid in the concave portion of the container may be a garbage bag or the like used at home, or a dedicated sheet according to the size of the concave portion of the container may be used. The dedicated sheet may be formed of only a liquid-impermeable material such as a polyethylene film, or may have a liquid absorbing layer. Examples of the sheet include a nonwoven fabric formed of hydrophilic or water-absorbing fibers on the surface side in contact with the excrement disposal material, a nonwoven fabric containing a superabsorbent polymer, or a paper sheet (tissue). In the liquid absorbing layer, a liquid-impervious layer such as a polyethylene resin on the back side facing the container and a liquid-impervious layer laminated on the liquid absorbing layer can be used.

When the exclusive sheet having the liquid absorbing layer is used, urine which seeps into the bottom of the concave portion of the container from between the excrement disposal materials can be absorbed. Urine does not seep or flow out of the sheet. In addition, even if the amount of the excrement disposal material is small and a cat or the like digs the excrement disposal material with claws and the bottom sheet is exposed, if the laminated sheet composed of the liquid absorbing layer and the impermeable liquid layer is made of polyethylene, Since the strength is higher than that of the film, the sheet is not broken by the nail.

Further, the liquid absorbing layer may contain a deodorant, an antibacterial agent and the like.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a pet toilet of the present invention cut along line II, and FIG.
FIG. 2 is a view of FIG. 1 viewed from the direction of arrow II, that is, a cross-sectional view of the pet toilet. The pet toilet T of the present invention includes a container 3 and a cover member 5. Container 3
It is made of plastic or the like, and has a substantially rectangular shape with a concave portion 3a having an open upper surface.

The cover member 5 has a frame shape formed in accordance with the shape of the opening edge 3b and the inner wall 3c of the container 3.
The cover member 5 fits into the opening edge 3b of the container 3 and has a substantially U-shaped cross section. The cover member 5
Upper surface portion 5a installed on the upper surface of opening edge 3b of container 3
And an inner surface portion 5b covering an inner wall 3c of the concave portion 3a of the container 3.
And an outer surface portion 5c that covers the outside of the container 3. When the pet toilet T is used, a liquid-impermeable sheet 4 is laid on the inner surface of the recess 3 a of the container 3. The liquid-impervious sheet 4 includes a bottom 3d and an inner wall 3 of the container 3.
The container 3 is laid so as to cover the inner surface thereof and further cover the opening edge 3b of the container 3.

The liquid-impervious sheet 4 may be a general garbage bag made of polyethylene resin or polyvinyl alcohol resin, or a special polyethylene resin sheet according to the size of the container. It may be. Alternatively, a laminated sheet having a liquid absorbing layer on the front side and an impermeable layer on the back side facing the container may be used. These sheets may be simply laid on the inner surface of the container, or as shown in FIG. 2, a sheet having an adhesive portion 6 formed on the back surface, and the adhesive portion 6 is used to form the concave portion 3a of the container. May be adhered to the bottom 3d, the inner wall 3c, and the opening edge 3b. Alternatively, the liquid-impermeable sheet 4 may be fixed at the opening edge 3b of the concave portion 3a of the container 3 with an adhesive tape or the like.

In any case, since the peripheral portion of the liquid-impermeable sheet 4 is sandwiched between the opening edge 3b of the container 3 and the cover member 5, the liquid-impermeable sheet 4 can be provided without providing the adhesive portion 6.
Is not detached from the container 3. However, by providing the adhesive portion 6, the liquid-impermeable sheet 4 on the container 3 is provided.
Misalignment can be prevented. A granular excrement disposal material 2 such as cat litter is placed in the concave portion 3 a of the container 3 covered with the liquid impermeable sheet 4. As the excrement disposal material 2, particles of zeolite and bentonite which are generally used,
Alternatively, cellulose particles, or those obtained by coating a surface of a cellulose particle with a water-absorbing polymer are used.

As shown in FIG. 2, the height from the bottom 3d of the container 3 to the surface of the excrement disposal material 2 is β when the excrement disposal material 2 is inserted, and the cover 3 is provided from the bottom 3d of the container 3. When the distance from the inner surface 5b of the member 5 to the lower end 5d is α, it is preferable that α <β, and more preferably, the difference between α and β is as large as possible. If α and β are approximately the same distance, when the cat stirs the excrement disposal material 2, the liquid-impermeable sheet 4 appears below the inner surface 5b of the cover member 5, and the liquid-impermeable sheet 4 4 may be caught by the cat's claw and torn, and there is a possibility that urine or the excrement disposal material 2 may enter between the liquid impermeable sheet 4 and the concave portion 3a of the container 3 from the torn.

Also, the excrement disposal material may enter between the lower end 5d of the inner surface 5b of the cover member 5 and the liquid impermeable sheet 4, and the cover member 5 may float. Therefore, for example, when β is about 5 cm, α is about 1 cm to 2 cm so that the inner surface 5 b of the cover member 5 is at the bottom 3 d of the container.
A structure that extends long toward is preferred. When the inner surface 5b of the cover member 5 is extended in the direction of the bottom 3d, the liquid-impermeable sheet 4 can be reliably pressed against the inner wall 3c of the container 3 by the cover member 5, and The conductive sheet 4 can be prevented from floating from the bottom 3d of the container 3.

FIG. 3 is a sectional view of another pet toilet according to the present invention. The pet toilet shown in FIG. 3 is different from the pet toilet shown in FIGS. 1 and 2 only in the shape of the cover member, and the other members are the same. The cover member 7 shown in FIG. 3 has a frame shape including an upper surface portion 7a, an inner surface portion 7b, and an outer surface portion 7c, and covers the inner wall portion 3c of the container 3.
A projecting portion 7e extending toward the inner wall 3c is formed at the lower end 7d of b. The protruding portion 7e extends to a position where the protruding portion 7e contacts the inner wall 3c of the container. The protruding portion 7e can press the liquid-impermeable sheet 4 on the inner wall 3c of the container 3 over the entire circumference of the container 3. It has a rib shape or a flange shape.

Since the liquid-impermeable sheet 4 is pressed against the inner side wall 3c by the protruding portion 7e, the floating of the sheet 4 can be effectively prevented. In addition, since the gap between the inner wall 3c of the container and the lower end 7d of the inner surface 7b is closed by the protruding portion 7e, it becomes difficult for the excrement disposal material or the like to enter the gap, and the cover member 7 is prevented from floating. Further, the excrement disposal material 2 containing urine and the like does not enter between the cover member 7 and the sheet 4, which is sanitary. In this pet toilet T, as in the prior art, every time a cat excretes, the excrement disposal material 2 that has been soiled with excrement is removed,
Add new waste management material. Since the inner surface of the concave portion 3a of the container 3 is completely covered with the liquid-impermeable sheet 4,
Urine and stool can be prevented from adhering to the inside of the concave portion 3a of the container 3.

When the entire excrement disposal material 2 in the toilet T is replaced once every one to two weeks, first remove the cover member 5 or 7 and hold the end of the liquid-impermeable sheet 4. The excrement disposal material 2 is wrapped in the liquid impermeable sheet 4 and the excrement disposal material 2 is discarded together with the liquid impermeable sheet 4.
Since the excrement disposal material 2 is wrapped in the liquid-impermeable sheet 4 and transported to the trash box, the excrement disposal material 2 can be prevented from spilling while being transported to the trash box, and can be easily disposed of. After removing the liquid-impermeable sheet 4, the concave portion 3a of the container 3
Since the urine, stool, or excrement disposal material 2 does not remain, the container 3 does not need to be washed, and when the cover member 5 or 7 is dirty, only the cover member 5 or 7 needs to be washed. Is easy.

Further, the lower end of the outer surface portion 5c or 7c of the opening edge portion of the container of the cover member 5 or 7 is formed so as to wrap the outside of the opening edge portion, or a buckle or the like is provided to provide the outer surface portion 5c or 7c. The cover member may be hooked on the opening edge so that the opening edge of the container is sandwiched by the lower end of 7c. In this case, the cover member 5 or 7 is securely fitted to the opening edge of the container.

Further, instead of the liquid impermeable sheet 4,
When a laminated sheet (laminated sheet) is used in which the surface side is a liquid absorbing layer such as a nonwoven fabric or a paper sheet formed of hydrophilic fibers and the side facing the container is an impermeable layer such as polyethylene, the excrement disposal material 2 can be used. The transmitted urine can be absorbed by the liquid absorbing layer, and urine can be prevented from remaining on the surface of the sheet. Therefore, when the excrement disposal material is wrapped in the sheet and discarded, urine can be prevented from flowing out of the sheet. Further, since the laminated sheet has high strength, it is not easily broken even if it is scratched by a cat or the like. The target pet is not limited to a cat, but may be a dog or the like.

[0034]

As described above, according to the present invention, by laying a sheet on the inner surface of a container for a pet toilet, dirty excrement or excrement disposal material can be wrapped in the sheet and disposed. It is possible to prevent the excrement disposal material from being spilled while the excrement disposal material is being transported to the trash box without soiling the hands. Further, since the container can be prevented from being soiled by the sheet, the labor for cleaning the container can be omitted.

Further, by covering the cover member from above the sheet at the periphery of the container, the sheet does not shift even if the pet moves in the container. In addition, since the sheet does not directly appear on the surface of the container, it is possible to prevent the sheet from being torn by being caught by a pet's nail or the like.

Also, using the same container as a conventional toilet,
Only the cover member may be prepared, and the manufacturing cost is not required.
