Description

The present invention relates to a pet waste treatment device that is used in a pet toilet to scoop up waste treatment materials and the like.

There are a variety of pet litter boxes available for use when keeping pets such as cats and dogs indoors, as well as pet waste disposal tools such as scoops for use with these pet litter boxes. There are a variety of pet litter boxes available, including stand-alone types that only include a container for placing waste disposal material such as cat litter, and composite types that combine multiple parts.

A composite type pet toilet, for example, comprises an upper container, a tray, and a lower container. The upper container has a rectangular flat bottom on which waste treatment material that self-degrades when it absorbs moisture is laid. This bottom has a grid of through holes that allow the waste treatment material and urine to pass through. The tray is used to collect the self-degraded waste treatment material and urine, and may have a sheet-like treatment material recovery material attached to it that can be removed and attached. The upper container is placed on the upper side of the lower container, and the tray is stored below in a sliding manner.

Excrement treatment materials laid in single-item containers and in composite-type upper containers become partially soiled by pet urine, etc. The soiled excrement treatment materials are scooped up with a pet excrement treatment tool such as a shovel and discarded.

The pet waste disposal device described in Patent Document 1 comprises a scoop body and a movable member for sifting waste disposal material (called disposal material or cat litter in Patent Document 1) spread in a pet litter box. The scoop body has a tray in which a first through hole is formed. The movable member overlaps the tray so that it can move relative to the tray, and a second through hole is formed in the movable member. Sieve holes are formed in the area where the first through hole and the second through hole communicate. The size of the sieve holes can be changed by changing the relative position of the movable member to the tray.

This pet waste disposal device scoops up cat litter after pets have used it, and shakes it around to separate it into cat litter with excrement attached and the rest. This pet waste disposal device has adjustable sieve hole sizes, so it can be used with multiple types of cat litter of different sizes. The sifted cat litter is reused in the pet litter box. The cat litter remaining on the scoop body of the pet waste disposal device is discarded.

Patent No. 6543497

The pet waste disposal tool described in Patent Document 1 has a straight-line tip edge of the scoop body. The straight-line tip edge of the scoop body makes linear contact with the flat bottom surface, which does not have a slat-like through hole like a stand-alone pet toilet container, making it easier to scoop up waste disposal material laid on the bottom surface.

On the other hand, in a composite-type pet toilet, an excrement treatment material is placed in an upper container with a lattice-like through-hole. The through-hole of such an upper container can become clogged with the excrement treatment material. In particular, excrement treatment materials that self-decompose by absorbing moisture such as urine are prone to clogging the through-hole. However, a pet excrement treatment tool that has a scoop body with a straight-lined tip edge cannot eliminate clogging of the through-hole.

Non-self-disintegrating types of excrement treatment materials are also available. Non-self-disintegrating excrement treatment materials include water-repellent types made from powder or wood chips. These water-repellent types of excrement treatment materials produce powder, wood chips, and pet droppings, which can clog the through holes in the upper container.

The present invention aims to provide a pet waste treatment device that can unclog the through-holes in a pet toilet with a lattice-like through-hole even if the through-holes are clogged with waste treatment material.

The pet excrement disposal device according to the present invention comprises:
A pet waste disposal device for scooping up waste disposal material laid in a container having a lattice-like through-hole,
a bucket body having a linear tip portion and a peripheral portion other than the tip portion;
a peripheral wall portion surrounding a peripheral edge portion of the bucket body;
A plurality of comb-like protrusions protruding from a tip end of the bucket body;
Equipped with
The projection is formed to a size such that it can fit into a through hole provided in the container.

In the pet excrement disposal device according to the present invention,
The pitch of the plurality of protrusions matches the pitch of the through holes provided in the container.

In the pet excrement disposal device according to the present invention,
The bucket body is formed in a thin plate shape, and the peripheral edge is formed in a U-shape.

In the pet excrement disposal device according to the present invention,
The bucket body has a plurality of sieve holes.
In this pet waste disposal device, the width of the protrusions is formed to be narrower than the width of the sieve holes.

In the pet excrement disposal device according to the present invention,
The peripheral wall portion is formed to be thin.

The pet excrement disposal device according to the present invention comprises:
A handle is provided protruding from the peripheral wall.

The present invention provides a pet waste treatment device that can unclog the through-holes in a pet toilet with a slatted through-hole even if the through-holes are clogged with waste treatment material.

One embodiment of the pet waste disposal device according to the present invention will be described with reference to Figures 1 to 7, and an example of a pet toilet using this pet waste disposal device will be described with reference to Figures 8 to 13.

Prior to describing the pet waste disposal device, an example of a pet toilet A will be described with reference to Figs. 8 to 13. Fig. 8 is a perspective view showing an example of a pet toilet A according to the present invention. Fig. 9 is an exploded perspective view showing an example of a pet toilet A. Fig. 10 is a plan view showing an example of a pet toilet A. Fig. 11 is a cross-sectional side view showing an example of a pet toilet A. Fig. 12 is a cross-sectional side view of a main part of an example of a pet toilet A. Fig. 13 is a cross-sectional front view of a main part of an example of a pet toilet A.

As shown in Figures 8 and 9, pet toilet A is a type that uses pellet-shaped waste treatment material (not shown) and includes an upper container (container described in the claims) 1, a tray 2, a lower container 3, and a cover 4.

The upper container 1 has a rectangular flat bottom surface 11 with arc-shaped corners, and a frame-shaped peripheral wall 12 that surrounds the periphery of the bottom surface 11. The boundary between the bottom surface 11 and the peripheral wall 12 is a gently curved surface without any boundary lines such as creases. Each corner of the peripheral wall 12 is also curved without any boundary lines such as creases. The upper end of the peripheral wall 12 of the upper container 1 has a downward folded portion 121.

A waste treatment material that self-destructs when it absorbs moisture is laid on the bottom surface 11 of the upper container 1. The bottom surface 11 of the upper container 1 has a grid-like pattern of through holes 111 that are finer than the waste treatment material. When the waste treatment material absorbs moisture such as urine, it self-destructs and falls through the through holes 111.

As shown in FIG. 10, the through hole 111 is formed in an elongated hole shape by first ribs 111A and second ribs 111b that intersect in a lattice pattern. The width of the first rib 111a is, for example, 2 mm to 4 mm. The width of the second rib 111b is, for example, 2 mm to 4 mm. For example, the distance between adjacent first ribs 111a (width D of the through hole 111) is 2 mm to 5 mm, and the distance between adjacent second ribs 111b (length L of the through hole 111) is 15 mm to 40 mm, making the size of the through hole 111 larger than conventional through holes.

The through hole 111 is widened at the bottom so that it does not become clogged with the self-degrading excrement treatment material. Therefore, as shown in Figures 12 and 13, the first rib 111a and the second rib 111b have tapered surfaces so that the bottom of the through hole 111 is widened.

The tray 2 accumulates the excrement treatment material that collapses and falls from the through-hole 111. The tray 2 has a rectangular bottom surface 21 and a peripheral wall 22 that surrounds the outer periphery of the bottom surface 21. The bottom surface 21 of the tray 2 faces the bottom surface 11 of the upper container 1. The peripheral wall 22 of the tray 2 is formed into a frame shape having four corners by a front surface 221, a back surface 222, and a pair of side surfaces 223. The corners of the peripheral wall 22 of the tray 2 are also formed into a curved shape. The upper end of the peripheral wall 22 of the tray 2 is provided with a flange 224 that protrudes outward. The front surface 221 of the peripheral wall 22 of the tray 2 is provided with a recessed handle 225 for inserting fingers or for holding with fingers.

The tray 2 is deep and has the same depth as the upper container 1. That is, the peripheral wall 22 of the tray 2 is formed to be the same height as or higher than the peripheral wall 12 of the upper container 1. When the peripheral wall 22 of the tray 2 and the upper container 1 are the same height, the volume of the tray 2 and the volume of the upper container 1 are approximately the same. The height of the peripheral wall 22 of the tray 2 is, for example, about 20 mm to 100 mm. The illustrated tray 2 is deep and has the same depth as the upper container 1. As shown in Figures 9 and 11, a recess 226 is formed at each corner where the rear part 222 and each side part 223 of the tray 2 are connected. This recess 226 acts as a spout for discharging the waste treatment material accumulated in the tray 2 from the tray 2 when the tray 2 is tilted.

As shown in FIG. 11, the lower container 3 accommodates the tray 2 on its lower side so that it can slide freely, and the upper container 1 is placed on its upper side. As shown in FIG. 9, the lower container 3 has a rectangular bottom surface portion 31 and a frame-shaped peripheral wall portion 32 that surrounds the bottom surface portion 31. A pair of guide portions 311 (only one of which is shown) protrude from the bottom surface portion 31 of the lower container 3 so as to sandwich both sides of the tray 2.

The peripheral wall 32 of the lower container 3 has a height equal to the overlapping height of the peripheral wall 12 of the upper container 1 and the peripheral wall 22 of the tray 2. In other words, if the height of the peripheral wall 12 of the upper container 1 and the height of the peripheral wall 22 of the tray 2 are approximately the same, the height of the peripheral wall 32 of the lower container 3 will be approximately twice the height of the peripheral wall 12 of the upper container 1 and the height of the peripheral wall 22 of the tray 2. Therefore, the height of the peripheral wall 32 of the lower container 3 is, for example, approximately 110 mm to 290 mm.

The upper end of the peripheral wall 12 of the upper container 1 fits into the upper end of the peripheral wall 32 of the lower container 3. In addition, the folded portion 121 of the peripheral wall 12 of the upper container 1 abuts against the upper end of the peripheral wall 32 of the lower container 3, so that the upper container 1 does not fit into the lower container 3. The upper end of the peripheral wall 32 of the lower container 3 also has a folded portion 321 that faces downward.

An opening 33 is provided on the lower side of the front portion of the peripheral wall portion 32 of the lower container 3. The tray 2 stored on the lower side of the lower container 3 is completely pulled out of the lower container 3 through the opening 33. Therefore, the opening 33 is provided with the same size as the width and height of the tray 2.

A cover 4 is placed over the outer periphery of the upper container 1, specifically the upper part of the peripheral wall portion 12 of the upper container 1. As shown in Figures 8 and 9, the cover 4 has a peripheral wall portion 42, a fitting portion 43, and a step portion 44. The cover 4 does not have a top plate portion, and the area surrounded by the peripheral wall portion 42 is used as an entrance and exit portion for a pet to enter and exit the upper container 1.

The peripheral wall portion 42 of the cover 4 is formed in a frame shape by a front side, a back side, and a pair of side sides. The front side peripheral wall portion 42a is lower than the back side peripheral wall portion 42b. The pair of side side peripheral wall portions 42c are inclined in a curved shape at the upper edge so that they gradually become higher from the front side to the back side. The front side peripheral wall portion 42a is formed in a stepped shape.

The fitting portion 43 of the cover 4 includes a horizontal portion 431 and a downward portion 432. As shown in FIG. 11, the horizontal portion 431 protrudes laterally beyond the peripheral wall portion 42 of the cover 4 and abuts against the upper edge of the upper container 1. The downward portion 432 protrudes downward from the tip of the horizontal portion 431 and fits into the folded portion 321 of the lower container 3. The downward portion 432 of the fitting portion 43 fits into the folded portion 321 of the lower container 3, making it difficult for the cover 4 to come off the lower container 3, and the horizontal portion 431 of the fitting portion 43 abuts against the upper edge of the upper container 1, holding the upper container 1 from coming off.

The pet toilet A of this embodiment is configured as described above. Next, we will explain how to use this pet toilet A.

This pet toilet A is installed in a room such as a living room, with the tray 2 stored under the lower container 3, the upper container 1 placed over the lower container 3, and the cover 4 placed over the top of the peripheral wall 12 of the upper container 1. An excrement treatment material is laid on the bottom 11 of the upper container 1. The excrement treatment material is in the form of pellets larger than the through-hole 111 of the upper container 1. The excrement treatment material is, for example, cylindrical with a diameter of 6 mm and a length of 13 mm. The excrement treatment material is piled on the bottom 11 of the upper container 1. The excrement treatment material is piled in an amount less than the capacity of the upper container 1 so that it does not spill out of the upper container 1. The through-hole 111 is formed in an oblong shape slightly smaller than the excrement treatment material, which makes it easier for the excrement treatment material to be partially caught in the through-hole 111.

Pets enter upper container 1 through the entrance of cover 4. Pets may also enter upper container 1 by stepping on step portion 44. Pets urinate on the waste treatment material and exit upper container 1. By partially catching the waste treatment material in through-hole 111, pet toilet A encourages the pet's habit of digging up the waste treatment material and backfilling it. Cover 4 prevents excreta treatment material that has been dug up from scattering around.

The waste treatment material self-disintegrates due to the moisture in the urine, and passes through the through-holes 111 in the upper container 1 and falls onto the tray 2. The waste treatment material is smaller than the through-holes 111 and self-disintegrates, making it less likely to clog within the through-holes 111. In addition, the waste treatment material may expand slightly as it absorbs moisture, causing it to self-disintegrate to the same size as the through-holes 111. Because the bottom side of the through-holes 111 is wider, even if the top side becomes clogged, the waste treatment material does not rub against the first rib 111a and second rib 111b within the through-holes 111, making it less likely to clog and allowing it to fall smoothly.

The self-destructing excrement treatment material absorbs moisture and expands slightly, and is deposited on the tray 2. The tray 2 is deep, either as deep as the upper container 1 or as deep as the lower container 3, and therefore can store more excrement treatment material than a thin tray 2 equipped with a sheet-like treatment material recovery member. The excrement treatment material on the upper container 1 decreases with each urination. This allows the amount of self-destructing excrement treatment material deposited on the tray 2 to be estimated. Even if the tray 2 is as deep as the upper container 1 or has the same or larger capacity as the upper container 1, the excrement treatment material is deposited in the upper container 1 in a smaller amount, so that even if it expands slightly, it will not overflow into the tray 2. In this way, the tray 2 can store more excrement treatment material than a conventional tray.

The tray 2 is completely pulled out from the lower container 3 before the self-degraded waste treatment material reaches its limit of accumulation on the tray 2. Because the tray 2 is deep, the tray 2 can be pulled out from the lower container 3 less frequently than a thin tray 2. Because a handle 225 is provided on the front portion 221 of the peripheral wall portion 22 of the tray 2, the tray 2 can be easily pulled out completely from the lower container 3. When the tray 2 is tilted, the waste treatment material in the tray 2 flows out from the recessed portion 226 of the tray 2 and is discarded into a human toilet, etc.

The empty tray 2 is stored under the lower container 3. A pair of guides 311 protrude from the bottom surface 31 of the lower container 3, so the tray 2 is inserted straight to the back without deflection. Any remaining waste treatment material in the upper container 1 is replenished.

Now, an embodiment of a pet waste disposal tool B for use in such a pet toilet A will be described with reference to Figs. 1 to 7. Fig. 1 is a perspective view showing an embodiment of a pet waste disposal tool B according to the present invention. Fig. 2 is a front view showing an embodiment of a pet waste disposal tool B according to the present invention. Fig. 3 is a right side view showing an embodiment of a pet waste disposal tool B according to the present invention. Fig. 4 is a left side view showing an embodiment of a pet waste disposal tool B according to the present invention. Fig. 5 is a bottom side view showing an embodiment of a pet waste disposal tool B according to the present invention. Fig. 6 is a plan view showing an embodiment of a pet waste disposal tool B according to the present invention. Fig. 7 is a rear view showing an embodiment of a pet waste disposal tool B according to the present invention.

Pet waste disposal tool (hereafter referred to as "tool") B comprises a bucket body 5, a peripheral wall 6, and a number of protrusions 7. Tool B comprises a bucket body 5, a peripheral wall 6, and a number of protrusions 7. Tool B further comprises a handle 8 and a hook 9.

As shown in Figures 3 and 4, the bucket body 5 is thin (e.g., about 1 mm to 5 mm thick) and has a concave front side, i.e., is bent gently in an inverted U shape so as to protrude downward when in use. As shown in Figures 1, 2, and 7, the bucket body 5 is U-shaped when viewed from the front and back. That is, the bucket body 5 has a straight tip 51 and a peripheral portion 52 other than the tip 51.

The peripheral portion 52 has a pair of side portions 521 that are continuous with each end of the tip portion 51, and an other end portion 522 that is continuous with the pair of side portions 521. The boundary portion 523 between the side portions 521 and the other end portion 522 is formed in an arc shape. The length from the tip portion 51 to the other end portion 522 is longer than the width of the pair of side portions 521. The bucket body portion 5 is formed in a rectangular shape with a pair of arc-shaped corners.

The bucket body 5 has a plurality of sieve holes 53 formed therein. The sieve holes 53 are arranged in a plurality of rows (six rows in the drawing) parallel to the side portion 521, and are arranged in a plurality of rows (three rows in the drawing) between the tip portion 51 and the other end portion 522. The sieve holes 53 are formed in an oval shape larger than the waste treatment material. Therefore, the sieve holes 53 are formed larger than the through holes 111 of the upper container 1. The width of the sieve holes 53 is, for example, 6 mm to 15 mm. The length of the sieve holes 53 is, for example, 6 mm to 35 mm.

The boundary portion 523 on the other end 522 side of the bucket body 5 is formed in an arc shape, so the sieve holes 53 close to this boundary portion 523 are formed shorter than the other sieve holes 53. The distance between adjacent sieve holes 53 is long in the length direction and short in the width direction. The bucket body 5 is bent in an inverted U shape from the other end side between the first row of sieve holes 53 and the second row of sieve holes 53.

The peripheral wall 6 is provided on the front side so as to surround the peripheral edge 52 of the bucket body 5. The boundary between the bucket body 5 and the peripheral wall 6 has a gently curved shape without any boundary line such as a crease. The peripheral wall 6 is formed thin, with a thickness similar to that of the thin plate-like bucket body 5. The upper edge of the peripheral wall 6 is formed in a straight line. As shown in Figures 3 and 4, the bucket body 5 is bent in an inverted L shape, so the distance between the upper edge of the peripheral wall 6 and the bucket body 5 gradually narrows toward the tip.

The multiple protrusions 7 protrude in a sawtooth shape from the tip 51 of the bucket body 5. The protrusions 7 are chamfered at the radius so as not to be angular. The multiple protrusions 7 are formed to a size that allows them to fit into the through holes 111 provided in the upper container 1 of the pet toilet A. In other words, the width of the protrusions 7 is narrower than the width of the through holes 111 in the upper container 1. The width of the protrusions 7 is formed to be smaller than the width of the sieve holes 53.

The pitch of the multiple protrusions 7 matches the pitch of the through holes 111 provided in the upper container 1. In other words, the distance between the protrusions 7 is the same as the width of the first rib of the upper container 1. In this way, the protrusions 7 protrude so that they can be inserted into adjacent through holes 111. Therefore, the distance between adjacent protrusions 7 is the same as the first rib 111a of the upper container 1. The length of the protrusions 7 is formed to be longer than the depth of the through holes 111 of the upper container 1.

As explained in the case of pet toilet A, when the through hole 111 of the upper container 1 is formed in an elliptical shape with a width D of 3 mm to 4 mm and a length L of 30 mm to 40 mm, the width of the protrusions 7 is formed to be 3 mm to 4 mm. When the width of the first rib 111a of the upper container 1 is formed to be 2 mm to 3 mm, the distance between the protrusions 7 is formed to be 2 mm to 3 mm. The protrusions 7 are formed to be longer than the plate thickness of the upper container 1 and to a length that is unlikely to break. The length of the protrusions 7 is formed to be, for example, about 7 mm to 12 mm.

As shown in Figures 1, 2 and 7, the handle 8 protrudes from the center of the peripheral wall 6. That is, the handle 8 protrudes from the upper end of the peripheral wall 6 provided at the other end 522 of the bucket body 5 in the opposite direction to the tip 51 of the bucket body 5 by approximately the same length as the bucket body 5. The handle 8 has a long, thin plate-shaped central portion 81 on the same plane as the upper edge of the peripheral wall 6, and a frame-shaped portion 82 provided downward from the periphery of this central portion 81.

The hook 9 protrudes upward from the center 81 of the handle 8. The hook 9 is L-shaped and has a leg 91 fixed to the center 81 of the handle 8 and a hanging support 92 protruding forward from the edge of the leg 91. The leg 91 is formed to the same height as the plate thickness of the upper container 1 of the pet toilet A. The processing tool B is in a vertical position with the tip 51 facing downward and the peripheral wall 6 aligned with the outer surface of the upper container 1 of the pet toilet A. Then, the hanging support 92 of the hook 9 and the center 81 of the handle 8 sandwich the upper container 1 of the pet toilet A, so that the processing tool B can be hooked onto the pet toilet A.

Processing tool B is configured as described above. Next, we will explain how to use this processing tool B.

An excrement treatment material that self-destructs when it absorbs moisture is laid in the upper container 1 of the pet toilet A. When a pet urinates on this excrement treatment material, the excrement treatment material self-destructs. The self-destructing excrement treatment material falls through the through-holes 111 in the upper container 1 and accumulates on the tray. However, if the excrement treatment material self-destructs to the same size as the through-holes 111 in the upper container 1, the through-holes 111 in the upper container 1 may become clogged with the excrement treatment material.

In such a case, the disposal tool B is removed from the upper container 1 of the pet toilet A. The disposal tool B is in an inclined position, and the protrusions 7 move from one end of the upper container 1 to the other, tracing the surface of the upper container 1, thereby scooping up feces on the upper container 1, excrement disposal material that has self-decomposed but not fallen, and excrement disposal material that has not self-decomposed. The feces and excrement disposal material are piled up on the bucket body 5 of the disposal tool B.

As the processing tool B is rocked, the feces and excrement processing material on the bucket body 5 is sieved out. Because the peripheral edge 52 of the bucket body 5 is surrounded by the peripheral wall 6, small pieces of excrement processing material fall through the sieve holes 53 of the processing tool B onto the upper container 1. The feces and large pieces of excrement processing material remain on the bucket body 5 without falling through the sieve holes 53 of the processing tool B. The excrement processing material remaining on the bucket body 5 is disposed of in a human toilet, etc.

Excrement processing material that is clogged in the through holes 111 of the upper container 1 is removed by the processing tool B. The multiple protrusions 7 of the processing tool B are inserted into the adjacent through holes 111 of the upper container 1. The protrusions 7 are chamfered at the radius, making them easy to insert into the through holes 111. The multiple protrusions 7 move from one end of the through holes 111 to the other end, or are inserted at multiple points, causing the clogged excrement processing material to fall onto the tray. Alternatively, the protrusions 7 of the processing tool B are inserted into the through holes 111 of the upper container 1, and the protrusions 7 are scraped up from downward to upward, causing the clogged excrement processing material to be scooped up onto the bucket body 5 of the processing tool B. The scooped excrement processing material is discarded.

In this way, the upper container 1, which has been cleared of clogging by the treatment tool B, is replenished with new excrement treatment material since the amount of excrement treatment material has decreased.

Although the embodiments of the present invention have been described above, the present invention is not limited to the configurations described in the above embodiments, and includes other embodiments and modifications that are possible within the scope of the matters described in the claims. Furthermore, various modifications and combinations of the above embodiments may be made without departing from the spirit of the present invention.

For example, in the above embodiment, the pitch of the multiple protrusions 7 of the processing tool B is the same as the pitch of the through holes 111 provided in the upper container 1. However, the pitch of the multiple protrusions 7 may be reduced, for example, to thin out the through holes 111 provided in the upper container 1.

In the above embodiment, the width of the protrusion 7 is formed narrower than the width of the sieve hole 53. However, the sieve hole 53 can be formed in any shape, and the width of the protrusion 7 may be formed wider than the width of the sieve hole 53. In addition, the bucket body 5 may not have a sieve hole 53.

In the above embodiment, the peripheral portion 52 of the bucket body 5 of the processing tool B is formed in a U-shape. However, the peripheral portion 52 of the bucket body 5 may be formed in a U-shape, a Λ-shape, an arc shape, or the like.

In the above embodiment, the bucket body 5 has a thin peripheral wall 6. However, the peripheral wall 6 may be thick or have an uneven thickness. Also, in the above embodiment, the bucket body 5 is bent in an inverted V shape. However, the bucket body 5 may be flat and not bendable, or may have a spoon-like recess.

In the above embodiment, the hook 9 protrudes from the handle 8. However, the handle 8 and the hook 9 do not necessarily have to be provided. In the above embodiment, the handle 8 protrudes from the center of the peripheral wall portion 6. The handle 8 may also protrude from the side portion of the peripheral wall portion 6.

In the above embodiment, the excrement treatment material is of a type that self-disintegrates when it absorbs moisture. However, the excrement treatment material may be of a type that does not self-disintegrate. An example of an excrement treatment material that does not self-disintegrate is a water-repellent type formed from powder or wood chips. This excrement treatment material produces powder, wood chips, and pet droppings, which can become clogged in the through-hole 111 of the upper container 1. In such a case, the excrement treatment tool B can scoop up the water-repellent excrement treatment material that has become clogged in the through-hole 111 of the upper container 1.

In summary, the pet waste disposal device B to which the present invention is applicable only needs to have the following configuration, and can take on a variety of different embodiments.

The pet excrement disposal device B according to the present invention is
A pet waste disposal device B for scooping up waste disposal material laid in a container 1 having a through hole 111 in a lattice shape,
A bucket body 5 having a linear tip portion 51 and a peripheral portion 52 other than the tip portion 51;
A peripheral wall portion 6 surrounding a peripheral edge portion 52 of the bucket body portion 5;
