Generally, when an animal kept indoors, such as a dog, urinates in an animal toilet, the urine discharged from the animal is drawn into the absorbent sheet from the liquid-permeable surface sheet of the absorbent sheet. , It is absorbed by the absorbent sheet by being held by the absorber between the front surface sheet and the liquid impervious back sheet. However, especially when the animal urinates a plurality of times, the amount of urine retained in the absorber increases and it becomes difficult for the urine to be drawn into the absorbent sheet, so that the urine before being drawn into the absorbent sheet becomes difficult. It may flow on the surface sheet of the absorbent sheet and spill out of the absorbent sheet (hereinafter, referred to as “leakage”). As a result, the leaked urine may contaminate the animal litter box, and it may take time for the animal breeder to clean the animal litter box.

In particular, when the animal is a dog, the discloser of the present invention tends to be reluctant to urinate again in the portion where the dog has urinated once when the dog urinates a plurality of times in the animal toilet. I got the knowledge about. Therefore, when the dog urinates a plurality of times, as the number of times of urination increases, the urinated area in the urination area for the dog to urinate in the toilet expands, and the dog urinates at the outer edge of the urination area. There is an increased risk that the leaked urine will leak out of the absorbent sheet.
Under such circumstances, when the animal urinates in the animal toilet described in Patent Document 1, the toilet is not intended to prevent the animal's urine from leaking out of the absorbent sheet. When an animal urinates multiple times, the animal's urine may leak out of the absorbent sheet.

Further, in order to prevent the leaked urine from leaking out of the absorbent sheet as described above, when the pet sheet is configured as disclosed in Patent Document 2, the animal is described in Patent Document 2. When urinating in the pet sheet, the flap portion has a function of being easily crushed when the animal enters the pet sheet and preventing the animal's urine from leaking out of the absorbent sheet from the edge of the sheet. As a result of the inhibition, there was still a risk that the animal's urine would leak out of the absorbent sheet.

Therefore, the present disclosure makes it easy to prevent the urine of the animal from leaking out of the absorbent sheet even if the animal urinates a plurality of times, and it is difficult to contaminate the animal toilet. It is an object of the present invention to provide an absorbent sheet and an animal toilet used for an animal toilet, which can easily reduce the trouble of cleaning the toilet.

It is a member that suppresses such things. The liquid permeable member 9 is formed so as to cover the central portion 17 and the leak-proof wall portion 21 in a plan view, and has a substantially square shape. When the animal toilet 3 is used, the liquid permeable member 9 is placed on the upper surface of the absorbent sheet 1 and overlaps with the absorbent body 31 at least in the thickness direction T to cover at least the absorbent body 31. However, "covering" the object means spreading from above the thickness direction T to one surface of the surface of the object and keeping the object in a state of being shielded from the outside world (hereinafter, the same applies). In another embodiment, the liquid permeable member 9 may cover at least a portion overlapping the central portion 17 in the thickness direction T, and at least from the central portion 17 to at least a part of the extending portion 19 in the thickness direction T. The overlapping part may be covered.

The liquid permeable member 9 is configured to be movable upward in the thickness direction T in response to the upward movement of the upper surface of the absorbent sheet 1 in the thickness direction T as the absorbent sheet 1 expands. .. The liquid permeable member 9 includes an upper mesh member 35 in the thickness direction T and a lower liquid passing filter 37.

The liquid passing filter 37 is formed so as to cover the absorber 31 mainly on the central portion 17 of the absorbent sheet 1 mounted on the central portion 17, that is, the mounting portion 7 in a plan view, and is more than the central portion 17. It has a substantially square shape that is one size smaller.
The term "one size smaller" means that the projected area in the thickness direction of the mounting surface of the liquid passage filter is 99 to 80% of the projected area in the thickness direction of the portion partitioned by the top of the leak-proof wall portion. Means that Here, the portion partitioned by the top is a portion partitioned by the innermost portion in the plane direction at the top when the top has a predetermined width in a plan view, and the top is When it exists discontinuously, it means a part partitioned by a virtual line connecting the tops and adjacent tops.

The liquid passage filter 37 allows the excrement flowing from the upper surface side to flow through the mesh member 35 toward the absorber 31 of the absorbent sheet 1 on the lower surface side, and can absorb and deodorize the excrement. The liquid passage filter 37 is a filter having a corrugated structure having a large number of holes (or gaps, openings, etc.) penetrating in the thickness direction T. The opening ratio of the liquid passage filter in a plan view is, for example, 50 to 90%. In the present specification, the aperture ratio of the object in a plan view is obtained by cutting out the surface of the object as a sample of 30 mm × 30 mm, calculating the area of the opening portion of the sample surface, and dividing by the sample area. Obtained as a percentage of the value obtained. Even if the absorbent sheet 1 absorbs a large amount of excrement to reduce the absorption rate or rewet and the excrement temporarily remains on the upper surface of the absorbent sheet 1, the excrement is a liquid passage filter. It is possible to prevent the excrement from reaching the mesh member 35 beyond 37, and it is possible to suppress the generation of odor due to the accumulation of excrement in the mesh member 35 or the like. The size of the liquid passage filter in a plan view is not particularly limited, and examples thereof include a size of 19 cm × 19 cm to 58 cm × 58 cm. In another embodiment, the liquid passing filter 37 may have a structure other than the corrugated structure having a large number of holes (or gaps, openings, etc.) penetrating in the thickness direction T.

In the present embodiment, as a preferred embodiment, the liquid permeable member 9 of the animal toilet 3 includes a liquid passing filter 37 located on the side of the absorbent sheet 1. Therefore, in such an animal toilet 3, the absorbent sheet 1 absorbs a large amount of excrement to reduce the absorption rate or rewet, so that the excrement is temporarily deposited on the upper surface of the absorbent sheet 1. Even if it remains, it is possible to prevent the excrement from reaching the upper surface of the liquid permeable member 9 (mesh member 35) beyond the liquid passage filter 37, and the excrement is accumulated in the liquid permeable member 9 to generate an odor. Can be suppressed.

The mesh member 35 covers the central portion 17 and the leak-proof wall portion 21, that is, a part of the liquid passing filter 37 and the outer peripheral edge portion of the absorbent sheet 1 extending to the outside of the liquid passing filter 37 in a plan view. It has a substantially square shape that is one size larger than the leak-proof wall portion 21. The mesh member 35 distributes the excrement excreted by the animal to the liquid passage filter 37 below the thickness direction T without accumulating the excrement. The size of the mesh member in a plan view is not particularly limited, and examples thereof include a size of 22 cm × 22 cm to 66 cm × 66 cm. The mesh member 35 includes a mesh portion 39 integrally formed and a frame portion 41. In another embodiment, the mesh portion 39 and the frame portion 41 may be formed separately and integrally formed by adhesion or the like.

The mesh portion 39 has a substantially square thin plate shape extending in the plane direction. The mesh portion 39 has liquid permeability so that excrement does not collect on the upper surface. Specifically, the mesh portion 39 has a honeycomb structure including a plurality of openings (or gaps, holes, etc.) penetrating in the thickness direction T. Examples of the aperture ratio include 50 to 90%. In another embodiment, the mesh portion 39 may have a structure other than the honeycomb structure having a plurality of openings (or gaps, holes, etc.) penetrating in the thickness direction T.

The frame portion 41 is a portion of the mesh member 35 other than the mesh portion 39, and is a substantially flat frame-shaped portion that extends in the plane direction. The frame portion 41 holds the mesh portion 39 inside the frame in the plane direction. The frame portion 41 is formed in the vertical direction L and the horizontal direction W corresponding to the sides 41-1, 41-2, 43-1, 41-4 extending in the vertical direction L and the horizontal direction W in the substantially square mesh portion 39. A movement limiting portion 43 is provided at substantially the center of each of the extending side portions in the vertical direction L and the horizontal direction W. The movement limiting portion 43 is a circular opening in a plan view, and a separate convex portion or the like within the size range of the opening can be inserted. In another embodiment, the movement restriction unit 43 may not be provided.

[Holding member]
The holding member 11 has a frame body 47 that holds the liquid permeable member 9 at its peripheral edge, and an opening 45 that is surrounded by the frame body 47 in the plane direction. The frame body 47 of the holding member 11 is formed so as to cover the peripheral edge portion of the liquid permeable member 9 and the peripheral edge portion of the central portion 17 of the mounting portion 7 in a plan view, and is one size larger than the liquid permeable member 9. It has a substantially square frame shape. The opening 45 corresponds to a region where the animal excretes excrement, that is, a region overlapping the absorber 31 of the absorbent sheet 1 in the thickness direction T. In other words, the opening 45 is provided at a position that substantially overlaps the central portion 17, the liquid passage filter 37, and the mesh portion 39 in a plan view. The size of the holding member in a plan view is not particularly limited, and examples thereof include a size of 27 cm × 27 cm to 90 cm × 90 cm.

The frame body 47 has a frame-like shape having an opening 45 inside in the plane direction, and the height in the thickness direction T decreases toward the inside of the frame (opening 45 side). It is tilted. Further, the frame body 47 includes an inner peripheral edge portion 49 and an outer peripheral edge portion 51.
The opening 45 is substantially the center of the holding member 11 in a plan view, but is located at a position slightly deviated to one side (for example, the rear side) of the vertical direction L and one side (for example, the right side) of the horizontal direction W. , Has a substantially square shape. Therefore, each side portion of the frame body 47 in FIG. 2, that is, the right side portion 47-1 and the left side portion 47-3 in the horizontal direction W, the rear side portion 47-2 and the front side portion 47 in the vertical direction L in the frame body 47. In -4, there are a narrow right side portion 47-1 and a rear side portion 47-2, and a wide left side portion 47-3 and a front side portion 47-4. However, the right side portion 47-1 and the rear side portion 47.2 and the left side portion 47-3 and the front side portion 47-4 have the same structure except that their widths are different. In another embodiment, the opening 45 may be located at the center of the holding member 11 in a plan view and not deviated in the vertical direction L and the horizontal direction W, that is, the right side portion 47-1 and the left side. The width may be the same as that of the portion 47-3, the rear side portion 47-2, and the front side portion 47-4.

Further, the frame body 47 has an opening 55 below the thickness direction T in the side surface portion 53 extending downward substantially perpendicularly to the thickness direction T from the outer peripheral edge portion 51. With such a configuration, the position of the absorbent sheet 1 can be adjusted by pulling the corner portion of the absorbent sheet 1 mounted on the mounting portion 7 from the opening 55 with a finger.

FIG. 5 is a perspective view of the holding member of the animal toilet of FIG. 1 as viewed from the back side. The holding member 11 extends from the edge on the side surface 53 side of the frame 47 to the edge on the opening 55 side on the back side of the frame 47, that is, on the lower side in the thickness direction T. It further includes one rib 57 and a plurality of second ribs 59.

First ribs 57 are provided at both ends of each side portion of the frame body 47 (right side portion 47-1, rear side portion 47-2, left side portion 47-3, and front side portion 47-4, respectively). Two second ribs 59 are provided between the first ribs 57 at both ends. In another embodiment, the first rib 57 may be provided at one place or three or more places on each side of the frame body 47, or the first rib 57 may not be provided. In still another embodiment, the second rib 59 may be provided at one or three or more points on each side of the frame body 47, or the second rib 59 may not be provided. In the holding member 11, the right side portion 47-1 and the rear side portion 47-2 and the left side portion 47-3 and the front side portion 47-4 all have the same structure except for the difference in width. , The first rib 57 and the second rib 59 in each side portion have the same structure except for the difference in dimensions corresponding to the width of each side portion.

Both the first rib 57 and the second rib 59 extend from the end on the side surface 53 side of the frame 47 to the opposite end so as to hold the frame 47 from the lower side in the thickness direction T. Has been done. Both the first rib 57 and the second rib 59 are integrally formed with the frame body 47 and the side surface portion 53. In another embodiment, the first rib 57 and the second rib 59 may be formed separately from the frame body 47 and / or the side surface portion 53, and may be adhered to each other.

The second rib 59 is formed with a protruding portion 59a projecting downward in the thickness direction T so as to be inserted into the opening of the movement limiting portion 43 of the frame portion 41 of the mesh member 35. Has been done.

The configurations of each part of the base member 5, each part of the absorbent sheet 1, each part of the liquid permeable member 9, and each part of the holding member 11 in the present embodiment have been described above, but each has a substantially square planar shape. Therefore, they have the same planar shape (including similar figures). In another embodiment, each part of the base member 5, each part of the absorbent sheet 1, each part of the liquid permeable member 9, and each part of the holding member 11 have a planar shape of a circle, an ellipse, a polygon, or a combination thereof. It may or may not have the same planar shape (including similar figures) with each other. However, since the central portion 17, the leak-proof wall portion 21, the absorbent sheet 1 and the liquid-permeable member 9 are sequentially laminated and covered with each other, they have substantially the same planar shape (including similar shapes). It is preferable to have.

The material used for forming the base member 5, the liquid permeable member 9, and the holding member 11 is not particularly limited, and may be a resin material or a metal. As for the liquid passing filter 37, pulp may be mentioned in addition to the above. The method for forming the base member 5, the liquid permeable member 9, and the holding member 11 is not particularly limited, and examples thereof include compression molding, injection molding, and blow molding when the material is a resin material. When the material contains a material other than the resin material, a method of cutting out a member from the material and adhering the members to each other with an adhesive or the like, or a method of joining by welding or the like can be mentioned.

Further, in the present embodiment, the animal toilet 3 includes a base member 5, a liquid permeable member 9, and a holding member 11, but in another embodiment, the animal toilet 3 is included in the base member 5. The mounting portion 7 may be provided, and the liquid permeable member 9 and the holding member 11 may not be provided.

[Arrangement of absorbent sheets, etc.]

Next, a state in which the base member 5, the absorbent sheet 1, the liquid permeable member 9, and the holding member 11 are laminated, that is, the state of FIG. 1 in which the absorbent sheet 1 is arranged will be described. However, in the animal toilet 3, the parts of the base member 5, the liquid permeable member 9 and the holding member 11 corresponding to the parts of each side of the holding member 11 are the parts of each side of the animal toilet 3. The width of each side of the animal toilet 3 is different from that of the holding member 11, except that the width of the extension portion 19 corresponding to each side is different. Both have the same structure. Therefore, in the following, the laminated state of each side portion of the animal toilet 3 corresponding to the narrow right side portion 47-1 of the holding member 11 will be described. FIG. 3 is an end view of the animal toilet of FIG. 1 along III-III.

The absorbent sheet 1 is placed on the upper surface of the mounting portion 7 of the base member 5. Specifically, the absorbent sheet 1 is placed on the upper surface of the mounting portion 7 so that the absorbent sheet 1 covers the central portion 17, the leak-proof wall portion 21, and at least a part of the extending portion 19. Will be done. In this case, in the absorbent sheet 1, the absorber 31 or the flap portion 33 is along the surface including the inner base portion 21a and the top portion 21b of the leak-proof wall portion 21, and the flap portion 33 further forms the outer base portion 21c of the leak-proof wall portion 21. It is placed along the including surface so as to extend beyond the outer base 21c to the surface of the embankment 25. The outer end of the flap 33 extends to the outer extension 19 of the embankment 25.

In the present embodiment, the absorber 31 of the absorbent sheet 1 is arranged at a position overlapping the central portion 17 in the thickness direction T when the absorbent sheet 1 is placed on the mounting portion 7, and is an absorber. The outer edge 31a of the 31 in the plane direction is arranged so as to be located between the portion corresponding to the top portion 21b and the portion corresponding to the inner base portion 21a in the plane direction. That is, the outer edge 31a of the absorber 31 in the plane direction exists on the surface between the top portion 21b of the leakage-proof wall portion 21 and the inner base portion 21a.
In another embodiment, as will be described in the second embodiment described later, the outer edge 31a of the absorber 31 in the plane direction may be present inside the portion corresponding to the inner base portion 21a. In yet another embodiment, the absorbent sheet 1 is configured so that the absorbent body 31 exists up to the outer end thereof so as not to have a portion corresponding to the flap portion 33, and the outer edge of the absorbent body in the plane direction. 31a may be configured to extend to the extension portion 19.

The bank portion 25 extends outward by a predetermined width from the side surface portion in the lateral direction W. In another embodiment, the absorbent sheet 1 may have an outer end of the flap 33 located in a range between the inside of the central 17 and the outer base 21c of the leak-proof wall 21. In yet another embodiment, the absorbent sheet 1 is separated so that the absorber 31 or flap 33 does not follow the surface of any of the inner base 21a, top 21b and outer base 21c of the leak-proof wall 21. May be good.

Further, in the present embodiment, the four corners of the flap portion 33 of the absorbent sheet 1 extend to the outside of the leak-proof wall portion non-arranged portion 23 in the plane direction.

A liquid permeable member 9 is placed on the upper surface of the absorbent sheet 1. Specifically, the liquid passage filter 37 of the liquid permeable member 9 is placed on the upper surface of the absorbent sheet 1. At this time, since the liquid passing filter 37 is located inside the leak-proof wall portion 21 in a plan view, it can directly contact the upper surface of the absorbent sheet 1. Further, a mesh member 35 is placed on the upper surface of the liquid passing filter 37. Specifically, the mesh portion 39 of the mesh member 35 covers the portion excluding the peripheral portion of the central portion 17 in a plan view, and the frame portion 41 of the mesh member 35 is the peripheral portion of the central portion 17 and the leakage-proof wall portion. It covers the bank portion 25 (part) of the extension portion 19 and the extension portion 19. Here, when the liquid passing filter 37 and the absorbent sheet 1 are laminated, the height of the upper surface of the liquid passing filter 37 is the height of the leak-proof wall portion 21 as the height in the thickness direction T with respect to the central portion 17. It is equal to or higher than the height of the top 21b.

The liquid passing filter 37 is located inside the leak-proof wall portion 21 in a plan view. Further, the mesh member 35 covers the central portion 17, the leak-proof wall portion 21, and the bank portion 25 of the extending portion 19 in a plan view.

A holding member 11 that covers above the peripheral edge of the liquid permeable member 9 is placed on the upper surface of the extending portion 19 of the base member 5. At that time, in the frame body 47, the inner peripheral edge portion 49 is inside the inner peripheral portion 21a of the leak-proof wall portion 21 in the plane direction and the outer peripheral edge portion 51 is outside the outer base portion 21c of the leak-proof wall portion 21 in the plane direction. Be placed. In the second rib 59 of the frame body 47, the lower surface is in contact with the extending portion 19, and the inner surface (opening 45 side) faces the side surface portion of the mesh member 35.

The outer end of the flap portion 33 of the absorbent sheet 1 is inserted and sandwiched between the bank portion 25 and the first rib 57 and the second rib 59. Therefore, the first rib 57 and the second rib 59 of the frame body 47 function as a pressing member that directly presses the absorbent sheet 1. Further, the protruding portion 59a of the second rib 59 functions as a pressing member that indirectly presses the absorbent sheet 1 via the mesh portion and the liquid passing filter 37.

Next, the actions of the absorbent sheet 1 and the animal toilet 3 will be described in comparison with the conventional absorbent sheet and the animal toilet.
FIG. 4 is a schematic view showing the flow of urine U in the absorbent sheet 1 corresponding to the enlarged portion of the main part of FIG. FIG. 8 is a schematic view showing the flow of urine U'in the absorbent sheet 1'corresponding to the enlarged portion of the main part of the conventional animal toilet 3'.

The conventional animal toilet 3'shown in FIG. 8 includes a protrusion 61 for engaging with a member corresponding to the holding member 11 of the present embodiment, but the toilet 3'is absorbable by animal urine U'. Since it is not intended to suppress leakage to the outside of the sheet 1, there is a risk that the urine of the animal may leak to the outside of the absorbent sheet 1, especially when the animal urinates a plurality of times. More specifically, the animal urinates in the animal toilet 3'multiple times, and the urine U'is less likely to be drawn into the absorbent sheet, so that the urine U'before being drawn into the absorbent sheet 1' However, when it flows on the surface sheet 27'of the absorbent sheet 1'and spills out of the absorbent sheet 1', that is, when it leaks along the surface sheet 27' of the absorbent sheet 1'(urine U'). (When it flows like arrow A1'), the protrusion 61 is hard to exert the leak-proof function, so urine U'flows on the sheet 1'as arrows A2', A3', A4', and finally. Urine U'is likely to leak out of sheet 1'as shown by arrow A5'.

On the other hand, in the present embodiment, the animal toilet 3 is provided with a leak-proof wall portion 21, and is configured to cover the leak-proof wall portion 21 when the absorbent sheet 1 is placed on the mounting portion 7. Has been done. Therefore, when the absorbent sheet 1 is used in the animal litter box 3, the animal urinates in the animal litter box 3 a plurality of times, and the urine U is less likely to be drawn into the absorbent sheet. Even if the urine U before being drawn flows along the surface sheet 27 of the absorbent sheet 1 (when the urine U flows as shown by the arrow A1), the leaked urine U is prevented in the absorbent sheet. It is blocked by a portion corresponding to the leak wall portion, and it is easy to prevent leakage to the outside of the absorbent sheet 1 (urine U is difficult to flow as shown by arrow A2).
Further, even if the leaked urine U cannot be completely blocked by the portion of the absorbent sheet 1 corresponding to the leak-proof wall portion 21 (even if the urine U flows as shown by the arrow A3), this implementation is carried out. Since the absorbent sheet 1 in the form is configured to cover at least a part of the extending portion 19, the urine U is collected by the outer edge portion of the absorbing sheet 1 extending in the portion corresponding to the extending portion 19. Hold in the absorbent sheet 1 (even if the urine U passes through the surface sheet 27 and moves toward the arrow A4, the outer edge portion of the absorbent sheet 1 makes it easy to contain the urine U in the absorbent sheet 1). It is easy to prevent urine from leaking out of the absorbent sheet 1, and eventually urine leaks into the animal toilet 3 to contaminate the toilet.
From the above, the absorbent sheet 1 can easily prevent the animal's urine from leaking to the absorbent sheet 1 even if the animal urinates a plurality of times, and as a result, the animal toilet 3 is less likely to be contaminated. It is easy to reduce the trouble of cleaning the toilet 3.

Further, in the present embodiment, the absorber 31 of the absorbent sheet 1 is arranged at a position overlapping the central portion 17 in the thickness direction T when the absorbent sheet 1 is placed on the mounting portion 7. The outer edge 31a of the absorber 31 in the plane direction is arranged so as to be located between the portion corresponding to the top portion 21b and the portion corresponding to the inner base portion 21a in the plane direction.

When an animal urinates multiple times, more urine is retained in the absorber, and even if the urine is drawn into the absorbent sheet (even if the urine U flows as shown by arrow A5), the urine becomes the absorber. It moves in the absorbent sheet without being held (urine U flows as shown by arrow A6) and seeps out from the front surface sheet or between the front surface sheet and the back surface sheet. That is, it may leak. However, since the absorbent sheet 1 of the present embodiment is placed as described above, the urine U is outside the absorbent sheet 1 in the plane direction from the portion corresponding to the top portion 21b of the leak-proof wall portion 21. It is difficult for bleeding to leak in the portion located in, and even if the animal urinates a plurality of times, it is possible to more reliably prevent the animal urine U from leaking out of the absorbent sheet 1. Further, since the outer edge 31a of the absorber 31 in the plane direction is placed so as to be located on the portion corresponding to the inner base portion 21a or outside the portion in the plane direction, even if the animal urinates a plurality of times. On the surface sheet 27, urine is less likely to collect in the portion corresponding to the boundary portion between the leak-proof wall portion 21 and the central portion 17 (that is, the inner base portion 21a of the leak-proof wall portion 21), and animal urine is absorbed. Since it is easy to prevent the animal from leaking on the surface of 1, even if the animal urinates a plurality of times, it is easy to more reliably suppress the animal urine U from leaking out of the absorbent sheet 1.

Further, since the animal toilet 3 includes a frame body 47 having the above-described configuration, when the absorbent sheet 1 is placed on the mounting portion 7, the absorbent sheet 1 is placed along the leak-proof wall portion 21. It is easy to maintain the placed state, and it is easy to prevent the leaked urine from leaking to the outside of the absorbent sheet 1 by being blocked by the portion of the absorbent sheet 1 corresponding to the leak-proof wall portion 21. Further, in the animal toilet 3, the animal easily urinates in the central portion 17 which is the urination region, inside in the plane direction, that is, at a position away from the leak-proof wall portion 21. Therefore, when the absorbent sheet 1 of the present embodiment is used for the animal toilet 3, even if the animal urinates a plurality of times, the urine discharged from the animal corresponds to the leak-proof wall portion 21 in the absorbent sheet 1. It is difficult to reach the part to be urinated, and it is easy to prevent leakage to the outside of the absorbent sheet 1.

In the present embodiment, since the frame body 47 has a pressing member having the above configuration (the first rib 57 of the frame body 47, the second rib 59, and the protruding portion 59a of the second rib 59), the present embodiment When the absorbent sheet 1 is used for the animal toilet 3, it is easy to prevent the absorbent sheet 1 from shifting from a desired position, and even if the animal urinates a plurality of times, the animal urine U remains in the absorbent sheet 1. It is easier to prevent leakage to the outside more reliably.

Further, in another embodiment, when the surface of the leak-proof wall portion 21 between the inner base portion 21a and the top portion 21b is inclined outward in the plane direction, that is, between the inner base portion 21a and the top portion 21b. When the surface of the sheet is erected so as to be inclined toward the outer base portion 21c, the leak-proof wall portion 21 has such a structure. Therefore, when the absorbent sheet 1 is used for the animal toilet 3, the absorption is concerned. Since the sex sheet can be easily positioned when it is placed on the mounting portion 7 and can be easily removed from the mounting portion 7 without being caught by the leak-proof wall portion 21 even after use, the animal toilet 3 by the animal breeder. It is easy to reduce the trouble of cleaning the toilet more reliably.

Further, since the four corners of the absorbent sheet 1 of the present embodiment extend outside the leakage-proof wall portion non-arranged portion 23 having the above configuration, the absorbent sheet 1 having a planar shape has a three-dimensional shape. Even if it is arranged on the mounting portion 7, it is easy to suppress looseness at the four corners of the absorbent sheet 1, and it is easy to suppress the separation and misalignment of the absorbent sheet 1 from the mounting portion 7. As a result, when the absorbent sheet 1 is used in the animal toilet 3, even if the animal urinates a plurality of times, it is easier to more reliably suppress the animal urine from leaking to the outside of the absorbent sheet 1.

Further, since the animal toilet 3 includes the liquid passing filter 37 having the above configuration, the liquid passing filter 37 can be removed from the weight of the liquid passing filter 37 or the central portion while ensuring the liquid passing property of the urine discharged from the animal. Since the movement in the plane direction is easily restricted, it is easy to prevent the absorbent sheet 1 existing below the liquid passage filter 37 from being displaced from a desired position. As a result, when the absorbent sheet 1 is used for the animal toilet 3, even if the animal urinates a plurality of times, it is easier to more reliably suppress the leakage of the animal's urine to the outside of the absorbent sheet 1.

Subsequently, the second and third embodiments of the animal toilet according to the present disclosure will be described. In each embodiment, the same members of the above-described first embodiment are designated by the same reference numerals, the description thereof will be omitted, and only the parts different from those of the first embodiment will be described.

[Second Embodiment]
A second embodiment of the animal toilet according to the present disclosure will be described.
FIG. 6 is a diagram showing an arrangement mode of the absorbent sheet 1 according to the second embodiment of the present disclosure, and is a diagram corresponding to FIG. 3 according to the first embodiment.
In the present embodiment, the differences from the first embodiment are the size of the absorbent body 31 in the absorbent sheet 1 in the plane direction and the outer edge of the absorbent body 31 when the absorbent sheet 1 is arranged in the animal toilet 3. This is the positional relationship between the 31b and the leak-proof wall portion 21.

In the present embodiment, the absorber 31 is arranged at a position overlapping the central portion 17 in the thickness direction T when the absorbent sheet 1 is mounted on the mounting portion 7, and is arranged in the plane direction of the absorber 31. The outer edge 31b is arranged so as to be located inside the portion of the leak-proof wall portion 21 corresponding to the inner base portion 21a in the plane direction.

Since the absorbent sheet of the present embodiment is arranged as described above, the absorbent sheet 1 has a portion corresponding to the inner base portion 21a or a portion located outside the portion, that is, a leak-proof wall portion. The flap portion 33 exists in the portion corresponding to 21. That is, in the absorbent sheet 1, the absorbent body 31 does not exist in the portion corresponding to the leakage-proof wall portion 21, and the thickness of the absorbent sheet 1 becomes thinner than the portion in which the absorbent body 31 exists. Therefore, the absorbent sheet is likely to be arranged along the leak-proof wall portion 21 in the portion corresponding to the leak-proof wall portion 21. As a result, even if the animal urinates a plurality of times in the animal toilet 3 and the urine leaks on the surface sheet of the absorbent sheet 1, the leaked urine reaches the leak-proof wall 21 of the absorbent sheet 1. It is blocked by the corresponding portion, and it is easier to more reliably prevent leakage to the outside of the absorbent sheet 1.

However, the absorber overlaps the central portion by at least 60% or more, preferably 70% or more in the thickness direction. This is from the viewpoint of ensuring the absorbency of the absorbent sheet.

[Third Embodiment]
Subsequently, a third embodiment of the animal toilet according to the present disclosure will be described.
FIG. 7 is a perspective view showing a configuration example of the animal toilet according to the third embodiment of the present disclosure to which the absorbent sheet according to the present disclosure can be applied.

In the present embodiment, on the extension portion 19, the animal toilet 3 has each side portion of the frame body 47, that is, the right side portion 47-1 and the left side portion 47-3 of the horizontal direction W in the frame body 47, in the vertical direction. A fence portion 63 is provided along the outer peripheral edge portion 51 of the rear side portion 47-2 and the front side portion 47-4 of L.
The fence portion 63 has its surfaces 63-1, 63-2, 63-3, 63-4 at positions corresponding to the respective sides 47-1, 47-2, 47-3, 47-4 of the frame body 47. Each surface is provided with rod-shaped fences at intervals of 20 mm. In the present embodiment, the fence portion 63 is composed of only four surfaces, but in another embodiment, the fence portion 63 may further include surfaces constituting the ceiling portion in addition to the four surfaces.

In the present embodiment, the fence portion 63 is provided with an opening 63a on the surface 63-3 through which an animal can enter the animal toilet 3. The opening can be appropriately changed according to the size of the animal to which the animal toilet is applied, but it is preferable that the opening has a size of approximately 200 × 200 mm to 900 × 900 mm. Further, the openings may be provided on two or more surfaces of the fence portion, or may be configured to be openable and closable.

In the present embodiment, the fence portion 63 is installed so as to surround the absorbent sheet 1 in a plan view. More specifically, after arranging the absorbent sheet 1 in the first embodiment described above in the animal toilet 3, the fence portion 63 has an outer wall portion 13 and an outer peripheral edge portion 51 of the frame body 47 on the extending portion 19. It is arranged so as to fit in the gap 65 formed between the and.

Since the animal toilet 3 has the above configuration, when the absorbent sheet 1 is used for the animal toilet 3, even if the animal urinates a plurality of times, the animal urine is outside the absorbent sheet 1, and thus the extension portion. It is easier to more reliably suppress leakage to 19. As a result, the extension portion 19 and the fence portion 63 installed in the extension portion 19 are less likely to be contaminated, so that it is easier for the animal breeder to more reliably reduce the time and effort required to clean the animal toilet 3.

The absorbent sheet and the animal toilet used for the animal toilet according to the present disclosure are not limited to the above-described embodiments and exemplary descriptions, and are not deviated from the purpose and purpose of the present disclosure. It is possible to combine and change as appropriate.
