Summary of the Invention

Problems to be Solved by the Invention

[0004] Here, in the waste container as described above, in the outermost through hole among the plurality of through holes for allowing urine to pass through, the generation of urine accumulation at its outer peripheral portion becomes a problem.

[0005] The present disclosure has been made in view of the above circumstances, and an object thereof is to provide a waste container for a pet toilet that can suppress the generation of urine accumulation.

Means for Solving the Problems

[0006] A waste container according to one aspect of the present disclosure is a waste container including a bottom surface portion having a substantially rectangular shape in plan view for receiving urine excreted by a pet. The bottom surface portion has a lattice portion having a plurality of through holes arranged in the short - hand direction and a plurality of crossbars respectively provided between adjacent through holes, and a guide portion provided around the lattice portion so as to surround the lattice portion. The guide portion is inclined downward toward the outermost through hole in the lattice portion, and in a horizontally installed state, the height of the lower end of the guide portion is higher than the height of the surface of the crossbar.

[0007] In one aspect of the excretion container according to this disclosure, the height of the lower end of the guide portion, which slopes downward toward the through hole at the outermost end of the grate portion, is higher than the height of the slats of the grate portion. With this configuration, because the guide portion is sloped, urine flowing along the guide portion can easily reach the through hole at the outermost end. Also, because the height of the lower end of the guide portion is higher than the height of the slats, the urine flowing along the guide portion can be properly directed to the through hole. As described above, the excretion container according to this disclosure can properly direct urine to the through hole, suppress the occurrence of urine accumulation and suppress the generation of urine odor. Furthermore, the excretion container according to this disclosure can suppress the formation of urinary stones caused by urine accumulation. By suppressing the formation of urinary stones, it is possible to prevent the deterioration of appearance caused by the formation of urinary stones and reduce the burden of removing urinary stones.

[0008] When installed horizontally, there does not need to be a horizontal section between the lower end of the guide section and the outermost through-hole. With this configuration, there is no section (horizontal section) where urine that has passed through the guide section remains, so the formation of urine accumulation and the formation of urinary stones caused by urine accumulation can be suppressed more effectively.

[0009] The slatted section further has an inclined section that slopes downward from the lower end of the guide section toward the outermost through hole, and the inclination angle of the inclined section may be greater than the inclination angle of the guide section. With this configuration, the urine that has passed through the guide section gains even more momentum due to the inclined section with a larger inclination angle before reaching the through hole, so that the formation of urine accumulation and the formation of urinary stones caused by urine accumulation can be more effectively suppressed.

[0010] The lower end of the guide portion may be continuous with the outermost through-hole. By having the lower end of the guide portion directly continuous with the through-hole, urine can be directed from the guide portion to the through-hole without passing through an intermediate section where urine accumulates. This allows for more effective suppression of urine accumulation and the formation of urinary stones caused by such accumulation.

[0011] When installed horizontally, the surface height of the multiple struts may be higher for struts located on the outside in the short direction and lower for struts located in the center in the short direction. With this configuration, the outer struts closer to the guide are higher and the inner struts further from the guide are lower, so that urine that reaches the inside can be reliably directed to the through-hole. In other words, the formation of urine accumulation and the formation of urinary stones caused by urine accumulation can be more effectively suppressed.

[0012] The central part of the crossbar in the short direction may be convex. With such a configuration, urine drainage from the crossbar is improved, which can more effectively suppress the occurrence of urine accumulation and the formation of urinary stones caused by urine accumulation.

[0013] The through-hole may be formed so that its shape widens from the middle to the bottom in the vertical direction. With such a configuration, urine drainage from the rail is improved, and the occurrence of urine accumulation and the formation of urinary stones caused by urine accumulation can be more effectively suppressed.

[0014] The back surface of the rails may have different heights depending on the area. With this configuration, urine drainage is improved for urine that reaches the back surface of the rails, thus more effectively suppressing the occurrence of urine accumulation and the formation of urinary stones caused by urine accumulation. [Effects of the Invention]

Mode for Carrying Out the Invention

[0017] Hereinafter, the excretion container according to the embodiment of this disclosure will be described with reference to the drawings. In each figure, the same or corresponding parts are denoted by the same reference numerals, and redundant explanations are omitted. The drawings are schematic, and the proportions of each dimension may differ from those of reality. In this embodiment, as an example of an excretion container, a "excretion container that partitions the internal space of a pet system toilet vertically and receives urine excreted by a pet" is described, but it is not limited to this. That is, the excretion container is not limited to the example of being a component of a pet system toilet, but may also be a configuration that receives urine excreted by a pet in a single-layer toilet (specifically, a toilet for clumping litter, etc.).

[0018] Figure 1 is a perspective view of the pet system toilet 1 according to this embodiment. The pet system toilet 1 according to this embodiment is, for example, a system toilet for the excretion of a pet cat. The pet system toilet 1 may be, for example, a system toilet suitable for keeping multiple large cats, having an excretion space about twice that of a typical system toilet. Specifically, the pet system toilet 1 may have a length of about 70 cm in the longitudinal direction, a length of about 47 cm in the short direction, and a height of about 28 cm. In the following, the longitudinal direction may be described as the Y direction, the short direction as the X direction, and the height direction as the Z direction. Note that the pet system toilet 1 may be a system toilet for the excretion of pets other than cats.

[0019] As shown in Figure 1, the pet toilet system 1 comprises a waste container 2, a lower container 3, an upper container 4, and a tray 5. In the following, in the Z direction (height direction), the direction of the upper container 4 as seen from the lower container 3 may be described as "up," and the direction of the lower container 3 as seen from the upper container 4 may be described as "down." Also, in the X direction (short side direction), the direction of the opening 40 side of the front wall 41 as seen from the rear wall 42 of the upper container 4 may be described as "front," and the direction of the rear wall 42 side as seen from the opening 40 may be described as "rear."

[0020] The excretion container 2 is a container that holds sand (not shown) that functions as toilet litter and also receives urine excreted by the pet. The excretion container 2 also functions as a partition that divides the internal space of the pet toilet system 1 into an upper space (the space partitioned by the excretion container 2 and the upper container 4) and a lower space (the space partitioned by the excretion container 2 and the lower container 3). The excretion container 2 has a liquid-permeable bottom surface 21 and a wall surface 22. The sand is a granular material that can absorb or permeate liquids such as urine. The sand may be made from bentonite that can cover feces and absorb liquids, wood or paper with a water-repellent coating, or zeolite, silica gel, or minerals with deodorizing properties, molded into approximately spherical shapes with a diameter of about 2 mm to 15 mm, and known materials may be used. In addition, sand that hardens may be used as sand. The sand is placed in the bottom surface 21. Pet waste passes through the sand and through the gaps in the bottom section 21, which is composed of slatted bars, and falls into the lower container 3 (more specifically, the tray 5 held in the lower container 3) located below the waste container 2. The waste container 2 is made of a resin such as plastic, but is not limited to this. Details of the waste container 2 will be described later.

[0021] Tray 5 is positioned below the waste container 2 and contains an absorbent sheet (not shown) that absorbs liquid (waste) that permeates the bottom surface 21. Tray 5 has a tray handle portion 51 that the user can use to pull it out. The tray handle portion 51 may be formed not only on the front side of tray 5 but also on the rear side. In this case, tray 5 is symmetrical front to back. In this way, because tray 5 is symmetrical front to back and has tray handle portions 51 on both the front and rear sides, it is possible to pull out tray 5 via the tray handle portion 51 even if the front and back of tray 5 are reversed. The area of ​​the absorbent sheet that absorbs liquid is fixed to some extent, but by reversing the front and back of tray 5, the orientation of the absorbent sheet can be changed, making it possible to absorb liquid in an area different from the area that has already absorbed liquid. In this way, by reversing the front and back of tray 5, one absorbent sheet can be used to its maximum potential. Tray 5 is formed to be smaller than the lower container 3 so that it can be housed inside the lower container 3 and swing. In the configuration shown in Figure 1, tray 5 is housed in a region shifted to one side in the Y direction within the lower container. In this embodiment, tray 5 is pulled out horizontally, but is not limited to this; for example, it may be pulled out diagonally upward.

[0022] The lower container 3 is a container that holds the tray 5 and partitions the lower space between it and the waste container 2. The lower container 3 houses the tray 5 so that it can be pulled out in a swingable manner. The lower container 3 is composed of a bottom surface 31 and wall surfaces 32, 33, 34, and 35. The bottom surface 31 is the part that faces the installation surface on which the pet system toilet 1 is installed. The bottom surface 31 is formed in a rectangular shape in plan view.

[0023] Wall surface 32 is a portion formed to rise upward from the front end of the bottom surface 31. An opening 320 for pulling out the tray 5 is formed in wall surface 32. Wall surface 33 is a portion formed to rise upward from the rear end of the bottom surface 31. Wall surfaces 34 and 35 are portions formed to rise upward from both ends in the Y direction of the bottom surface 31. A recess 400 for gripping when carrying is formed at the lower part of the center of wall surfaces 34 and 35 in the X direction. Wall surfaces 32, 33, 34, and 35 are formed continuously, and the entire circumference of the bottom surface 31 is surrounded by wall surfaces 32, 33, 34, and 35. The wall surface 22 of the excretion container 2 (specifically, the first side wall 221, second side wall 222, third side wall 223, and fourth side wall 224 (see Figure 2) described later) is fitted onto the upper ends of the wall surfaces 32, 33, 34, and 35. The upper container 4 is attached so as to cover the upper ends of the wall surfaces 32, 33, 34, and 35.

[0024] The upper container 4 is positioned above the waste container 2 and separates the upper section between it and the waste container 2. The upper container 4 has an opening 40 through which the pet enters and exits. As shown in Figure 1, the upper container 4 is composed of a front wall portion 41, a rear wall portion 42, and a pair of side wall portions 43, 44. In this embodiment, the front wall portion 41, the rear wall portion 42, and the pair of side wall portions 43, 44 are formed integrally (continuously). Also, the upper container 4 does not have a bottom surface and is penetrating in the vertical direction.

[0025] The front wall portion 41 is attached to the wall surface 32 of the lower container 3 and is formed to rise upward. An opening 40 for pets to enter and exit is formed at a predetermined position in the Y direction of the front wall portion 41. As will be described later, a grate portion 210 is provided at a position offset in one direction in the Y direction from the center of the bottom portion 21 of the excretion container 2. Multiple through holes are formed in the grate portion 210 and sand (toilet sand) is placed in it. By forming the opening 40 of the front wall portion 41 on the opposite side (opposite side in the Y direction) of the position where the grate portion 210 is offset, it is possible to create a structure that collects sand towards the back when viewed from the pet's entrance (opening 40), thus naturally guiding the pet to the back.

[0026] The rear wall portion 42 is a part that is attached to the wall surface 33 of the lower container 3 and is formed to rise upward. The side wall portion 43 is a part that is attached to the wall surface 34 and is formed to rise upward. The side wall portion 44 is a part that is attached to the wall surface 35 and is formed to rise upward.

[0027] Next, a detailed explanation of an example of waste container 2 will be given with reference to Figures 2 to 16.

[0028] Figure 2 is a plan view of the waste container 2 included in the pet toilet system 1. Figure 3 is a bottom view of the waste container 2. Figure 4 is a front view of the waste container 2. Figures 5 and 6 are perspective views of the waste container 2. As shown in Figures 2 to 6, the waste container 2 comprises a bottom surface 21 and a wall surface 22.

[0029] The wall surface 22 is a portion formed to rise upward from the periphery of the bottom surface 21. The wall surface 22 has a first side wall 221 and a second side wall 222 that are opposite to each other and formed along the Y direction, and a third side wall 223 and a fourth side wall 224 that are opposite to each other and formed along the X direction. The first side wall 221 is fitted to the upper end of the wall surface 32 (see Figure 1) of the lower container 3. The second side wall 222 is fitted to the upper end of the wall surface 33 (see Figure 1) of the lower container 3. The third side wall 223 is fitted to the upper end of the wall surface 34 (see Figure 1) of the lower container 3. The fourth side wall 224 is fitted to the upper end of the wall surface 35 (see Figure 1) of the lower container 3.

[0030] The bottom portion 21 is a plate-like member that is roughly rectangular in plan view. The bottom portion 21 has a slatted portion 210 and a sloping portion 211.

[0031] The slatted section 210 is the part where multiple through-holes 215 are formed and where sand (toilet sand) is placed. In the slatted section 210, slats are formed in a slatted pattern, and regular gaps (through-holes 215) are formed between the slats. As shown in Figure 2, the slatted section 210 is divided into a roughly rectangular area in plan view and has a first side 216 facing the first side wall 221, a second side 217 facing the second side wall 222, a third side 218 facing the third side wall 223, and a fourth side 219 facing the fourth side wall 224. The slatted section 210 is located at a position offset from the center of the bottom surface 21 in one direction in the Y direction, specifically at a position offset in the direction toward the fourth side wall 224. Details of the slatted section 210 will be described later.

[0032] The sloping portion 211 is the part that extends diagonally upward from the slatted portion 210 toward the wall surface 22. The sloping portion 211 is composed of a first portion 211a that extends diagonally upward from the first side 216 of the slatted portion 210 toward the first side wall 221, a second portion 211b that extends diagonally upward from the second side 217 toward the second side wall 222, a third portion 211c that extends diagonally upward from the third side 218 toward the third side wall 223, and a fourth portion 211d that extends diagonally upward from the fourth side 219 toward the fourth side wall 224.

[0033] Next, the details of the slatted section 210 will be described with reference to Figures 2 and 7 to 16. Figure 7 is a cross-sectional view showing the section along line VII-VII in Figure 2. Figure 8 is an enlarged view of region VIII shown in Figure 7. As shown in Figure 2, in the slatted section 210, multiple slats are formed in a slatted shape in the X direction (short side direction) and the Y direction (long side direction), and regular gaps (through holes 215) are formed between the slats. As is clear from the cutting line VII-VII in Figure 2, Figure 7 shows multiple through holes 215 and multiple slats 250 arranged in the X direction (short side direction). The bottom surface 21 has a slatted section 210 having multiple through holes 215 arranged in the X direction and multiple slats 250 provided between adjacent through holes 215. In this case, each slat 250 extends in the Y direction (long side direction). Furthermore, as shown in Figure 2, the bottom portion 21 has a sloped portion 211 (guide portion) provided around the slatted portion 210 so as to surround the slatted portion 210. As shown in Figure 7, in the X direction, the first portion 211a of the sloped portion 211 is provided in front of the slatted portion 210, and the second portion 211b of the sloped portion 211 is provided behind the slatted portion 210.

[0034] As shown in Figure 8, the first portion 211a of the guide portion, the inclined portion 211, is inclined downward toward the outermost through hole 215 in the slatted portion 210. When installed horizontally, the height of the lower end 211u of the first portion 211a is higher than the height of the surface 250a of the rib 250 (specifically, the highest part of the surface 250a). When set horizontally, there is no horizontal portion between the lower end 211u of the first portion 211a, the guide portion, and the outermost through hole 215. The slatted portion 210 further has an inclined portion 260 that is inclined downward from the lower end 211u of the first portion 211a, the guide portion, toward the outermost through hole 215. The inclination angle of the inclined portion 260 is greater than the inclination angle of the first portion 211a, the guide portion.

[0035] As shown in Figure 8, when installed horizontally, the height of the surface 250a of the multiple struts 250 may be higher for struts 250 located on the outside in the X direction and lower for struts 250 located on the inside (center). The central part of the struts 250 in the X direction may be convex.

[0036] The through hole 215 is formed such that its shape widens towards the bottom in the Z direction. The through hole 215 is formed such that its shape widens from at least the middle part towards the bottom in the Z direction, and may also be formed so that its shape widens from the top to the bottom, as shown in Figure 8.

[0037] Figure 9 is a cross-sectional view showing the section along the line IX-IX shown in Figure 2. Figure 10 is an enlarged view of region X shown in Figure 9. As is clear from the cutting line IX-IX in Figure 2, Figure 9 shows a plurality of through holes 215 and a plurality of ribs 270 arranged in the Y direction (longitudinal direction). The bottom surface 21 has a slatted section 210 having a plurality of through holes 215 arranged in the Y direction and a plurality of ribs 270 provided between adjacent through holes 215. In this case, each rib 270 extends in the X direction (short direction). The bottom surface 21 also has a sloped section 211 (guide section) provided around the slatted section 210 so as to surround the slatted section 210, as shown in Figure 2. As shown in Figure 9, in the Y direction, the third portion 211c of the sloped portion 211 is provided on one side of the slatted portion 210, and the fourth portion 211d of the sloped portion 211 is provided on the other side of the slatted portion 210.

[0038] As shown in Figure 10, the third portion 211c of the guide portion, the inclined portion 211, is inclined downward toward the outermost through hole 215 in the slatted portion 210. When installed horizontally, the height of the lower end 211v of the third portion 211c is higher than the height of the surface 270a of the crossbar 270 (specifically, the highest part of the surface 270a). When set horizontally, there is no horizontal portion between the lower end 211v of the guide portion, the third portion 211c, and the outermost through hole 215. The slatted portion 210 further has an inclined portion 280 that is inclined downward from the lower end 211v of the guide portion, the third portion 211c toward the outermost through hole 215. The inclination angle of the inclined portion 280 is greater than the inclination angle of the guide portion, the third portion 211c. The crossbar 270 may have a convex shape in the center in the Y direction.

[0039] Figure 11 illustrates the suppression of urine accumulation in the configuration of this embodiment compared to the comparative example. In the configuration of the comparative example shown in Figure 11(a), the tip of the guide portion 501, which is inclined downward toward the through hole 215, is continuous with the horizontal portion 502. In this case, urine UR that has passed through the guide portion 501 accumulates in the horizontal portion 502, which can lead to problems such as urine accumulation and the formation of urinary stones. In contrast, in the configuration of this embodiment shown in Figure 1(b), there is no horizontal portion between the lower end of the guide portion 300, which is inclined downward toward the through hole 215, and the through hole 215. Therefore, the formation of urine accumulation and urinary stones can be suppressed. Note that in the configuration shown in Figure 11(b), unlike the first portion 211a and the third portion 211c described above, the lower end of the guide portion 300 is continuous with the through hole 215.

[0040] Figure 12 is an enlarged view of area XII shown in Figure 3, that is, a partial enlarged view of the back (bottom) side of the slatted section 210. As shown in Figures 3 and 12, the slatted section 210 is formed in a substantially rectangular shape when viewed from the back side. The slatted section 210 has a lattice section 200 in which a plurality of slats 250 (first slats) extending in the Y direction (longitudinal direction) and a plurality of slats 270 extending in the X direction are arranged in a grid pattern, and a plurality of through holes 215 formed so as to be surrounded by each of the slats 250, 270. Here, the slats 250E, which are the slats 250 at both ends in the X direction, are formed to be thinner in the X direction than the other slats 250. Specifically, the thickness of the slats 250E, which are the slats 250 at both ends in the X direction, may be about 0.1 to 0.9 times the thickness of the other slats 250 in the X direction. For example, the thickness of the crossbar 250E at both ends in the X direction may be about 1.0 to 1.6 mm, and the thickness of the other crossbars 250 in the X direction may be about 1.5 to 2.5 mm.

[0041] Furthermore, the crossbars 270E, which are the crossbars 270 at both ends in the Y direction, are formed with a thinner thickness in the Y direction compared to the other crossbars 270. Specifically, the thickness in the Y direction of the crossbars 270E, which are the crossbars 270 at both ends in the Y direction, may be about 0.1 to 0.9 times the thickness in the Y direction of the other crossbars 270. For example, the thickness in the Y direction of the crossbars 270E, which are the crossbars 270 at both ends in the Y direction, may be about 1.0 to 1.6 mm, while the thickness in the Y direction of the other crossbars 270 may be about 1.5 to 2.5 mm.

[0042] Figure 13 is a perspective view of the back side of the slatted section 210, viewed from above in the X direction. Figure 14 is an end view of the slatted section 210 (end view viewed from the X direction). As shown in Figures 13 and 14, the back surface of the slats 250 (first slats) has different amounts of protrusion in each region in the Y direction (the height differs depending on the region). The back surface of the slats 250 is formed in an arch shape such that the amount of protrusion increases as it approaches the first intersection 291 where it intersects with one of the slats 270 (second slats) along the Y direction, and decreases as it moves away from the first intersection 291.

[0043] Figure 15 is a perspective view of the back side of the slatted section 210, viewed from above in the Y direction. Figure 16 is a cross-sectional view showing the section along line XVI-XVI shown in Figure 15. As shown in Figures 15 and 16, the back surface of the slat 270 (second slat) has different protrusion amounts in each region in the X direction (different heights in different regions). The back surface of the slat 270 is arched such that the protrusion amount increases as it approaches the second intersection 292 where it intersects with one of the slats 250 (first slat) along the X direction, and decreases as it moves away from the second intersection 292.

[0044] Next, the effects and benefits of the excretion container 2 according to this embodiment will be described.

[0045] The excretion container 2 according to this embodiment is an excretion container having a bottom surface 21 that is substantially rectangular in plan view to receive urine excreted by a pet, the bottom surface 21 having a slatted section 210 having a plurality of through holes 215 arranged in the short direction (X direction) and a plurality of rails 250 provided between adjacent through holes 215, and a first section 211a and a second section 211b that function as guide sections provided around the slatted section 210 so as to surround the slatted section 210, the first section 211a and the second section 211b are inclined downward toward the outermost through hole 215 in the X direction of the slatted section 210, and when installed horizontally, the height of the lower end 211u of the first section 211a and the second section 211b is higher than the height of the surface 250a of the rails 250.

[0046] In the excretion container 2 according to this embodiment, the height of the lower ends 211u of the first part 211a and the second part 211b, which function as guide parts inclined downward toward the through hole 215 at the outermost end of the grate part 210, is configured to be higher than the height of the surface 250a of the slats 250 of the grate part 210. With this configuration, because the first part 211a and the second part 211b are sloped, urine flowing down the first part 211a and the second part 211b can easily reach the through hole 215 at the outermost end. Also, because the height of the lower ends 211u of the first part 211a and the second part 211b is higher than the height of the surface 250a of the slats 250, urine flowing down the first part 211a and the second part 211b can be properly directed to the through hole 215. As described above, the excretion container 2 according to this embodiment can properly direct urine to the through hole 215, suppress the formation of urine accumulation, and suppress the generation of urine odor. Furthermore, the excretion container 2 of this embodiment can suppress the formation of urinary stones caused by urine accumulation. By suppressing the formation of urinary stones, it is possible to prevent the deterioration of appearance caused by the formation of urinary stones and to reduce the burden of removing urinary stones.

[0047] When installed horizontally, there does not need to be a horizontal section between the lower ends 211u of the first section 211a and the second section 211b and the outermost through-hole 215. With this configuration, there is no section (horizontal section) where urine that has passed through the first section 211a and the second section 211b remains, so the occurrence of urine accumulation and the formation of urinary stones caused by urine accumulation can be suppressed more effectively.

[0048] The slatted section 210 further has an inclined section 260 that slopes downward from the lower ends 211u of the first section 211a and the second section 211b toward the outermost through hole 215, and the inclination angle of the inclined section 260 may be greater than the inclination angle of the first section 211a and the second section 211b. With this configuration, the urine that has passed through the first section 211a and the second section 211b gains further momentum due to the inclined section 260 with a larger inclination angle before reaching the through hole 215, thereby more effectively suppressing the formation of urine accumulation and the formation of urinary stones caused by urine accumulation.

[0049] The lower ends 211u of the first part 211a and the second part 211b may be continuous with the outermost through hole 215. By having the lower ends 211u of the first part 211a and the second part 211b directly continuous with the through hole 215, urine can be sent from the first part 211a and the second part 211b to the through hole 215 without passing through a part where urine accumulates. This makes it possible to more effectively suppress the occurrence of urine accumulation and the formation of urinary stones caused by urine accumulation.

[0050] When installed horizontally, the height of the surface 250a of the multiple bars 250 may be higher for bars 250 located on the outside in the short direction (X direction) and lower for bars 250 located in the center in the X direction. With this configuration, the outer bars 250 closer to the first part 211a and the second part 211b are higher and the inner bars 250 further away from the first part 211a and the second part 211b are lower, so that urine that reaches the inside can be reliably directed to the through-hole 215. In other words, the occurrence of urine accumulation and the formation of urinary stones caused by urine accumulation can be more effectively suppressed.

[0051] The central part of the rib 250 in the short direction (X direction) may be convex. With such a configuration, the urine drainage of the rib 250 is improved, so the occurrence of urine accumulation and the formation of urinary stones caused by urine accumulation can be more effectively suppressed.

[0052] The through-hole 215 may be formed such that its shape widens from the middle to the bottom in the vertical direction. With such a configuration, urine drainage from the rail 250 is improved, and the occurrence of urine accumulation and the formation of urinary stones caused by urine accumulation can be more effectively suppressed.

[0053] The back surface of the crossbar 250 may have different heights depending on the area. With this configuration, urine drainage is improved for urine that reaches the back surface of the crossbar 250, so the occurrence of urine accumulation and the formation of urinary stones caused by urine accumulation can be more effectively suppressed.

[0054] The excretion container 2 according to this embodiment is an excretion container equipped with a bottom portion 21 for receiving urine excreted by a pet, the bottom portion 21 is equipped with a substantially rectangular slat portion 210 when viewed from the back side, the slat portion 210 is equipped with a lattice portion 200 in which a plurality of slats 250 (first slats) extending in the longitudinal direction (Y direction) and a plurality of slats 270 (second slats) extending in the short direction (X direction) are arranged in a grid pattern, and a plurality of through holes 215 each formed so as to be surrounded by each slat 250, 270, the slats 250E at both ends in the short direction (X direction) may be formed to be thinner in the X direction compared to the other slats 250.

[0055] In the excretion container 2 according to this embodiment, the thickness of the slats 250E at both ends in the X direction of the grate 210 is formed to be thinner than that of the other slats 250. For the slats 250 other than those at both ends in the X direction, urine tends to collect on them because they are adjacent to the adjacent slats 250 via slats 270, and urine that has accumulated to a certain weight tends to fall off. On the other hand, for the slats 250E at both ends in the X direction, urine does not tend to collect on them because they are adjacent to only one slat 250, and urine does not fall off, resulting in urine accumulation and making it easy for urinary stones to form. In this regard, because the thickness of the slats 250E at both ends in the X direction is formed to be thinner than that of the other slats 250, urine falls off more easily, so that urine can fall off properly even on the slats 250E at both ends in the X direction, where urine does not tend to collect as easily. This effectively suppresses the accumulation of urine and the formation of urinary stones on the slats 250E at both ends in the X direction.

[0056] The battens 270E at both ends in the longitudinal direction (Y direction) may be formed with a thinner thickness in the Y direction compared to the other battens 270. With this configuration, the thinner thickness of the battens 270E at both ends in the Y direction compared to the other battens 270 makes it easier for urine to drain, so that urine can be properly drained even at the battens 270 at both ends in the Y direction where urine tends not to accumulate. This effectively prevents urine from accumulating and causing urinary stones to form at the battens 270 at both ends in the Y direction.

[0057] The back surface of the crossbar 250 may have different protrusion amounts in each region in the Y direction. By having different protrusion amounts in each region of the back surface of the crossbar 250 in the Y direction, urine can be collected in areas with larger protrusions, promoting urine flow and effectively suppressing the formation of urinary stones.

[0058] The back surface of the crossbar 250 may be formed in an arch shape such that the amount of protrusion increases as it approaches the first intersection 291 where it intersects with any of the crossbars 270 along the Y direction, and decreases as it moves away from the first intersection 291. In this way, by increasing the amount of protrusion at the intersections where urine tends to collect, the flow of urine can be more appropriately promoted and the formation of urinary stones can be appropriately suppressed.

[0059] The back surface of the crossbar 270 may have different protrusion amounts between each region in the X direction. By having different protrusion amounts between each region in the X direction on the back surface of the crossbar 270 in this way, urine can be collected in areas with larger protrusions, promoting urine flow and effectively suppressing the formation of urinary stones.

[0060] The back surface of the crossbar 270 may be formed in an arch shape such that the amount of protrusion increases as it approaches the second intersection 292 where it intersects with any of the crossbars 250 along the X direction, and decreases as it moves away from the second intersection 292. In this way, by increasing the amount of protrusion at the intersections where urine tends to collect, the flow of urine can be more appropriately promoted and the formation of urinary stones can be appropriately suppressed.
