Description

[Technical Field]

[0001] The present disclosure relates to waste receptacles for pet litter boxes. [Background technology]

[0002] Patent document 1 discloses a pet toilet that includes a main body that receives excreted urine, and an excretion container that has multiple through holes that allow urine to pass through and divides the internal space of the main body into an upper space and a lower space. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2023-103503 Summary of the Invention [Problem to be solved by the invention]

[0004] In the excretion container as described above, among the plurality of through-holes through which urine passes, the outermost through-hole has a problem of urine pooling occurring around its outer periphery.

[0005] The present disclosure has been made in consideration of the above-described circumstances, and aims to provide an excrement container for a pet toilet that can prevent urine pooling. [Means for solving the problem]

[0006] An excretion container according to one aspect of the present disclosure is an excretion container having a bottom surface portion that is approximately rectangular in plan view and that receives urine excreted by a pet, the bottom surface portion having a slat portion with a plurality of through holes aligned in the short direction and a plurality of bars each provided between adjacent through holes, and a guide portion provided around the slat portion so as to surround the slat portion, the guide portion being inclined downward toward the outermost through hole of the slat portion, and when installed horizontally, the height of the lower end of the guide portion is higher than the height of the surface of the bars.

[0007] In one aspect of the excretion container according to the present disclosure, the height of the lower end of the guide portion, which slopes downward toward the through-hole at the outermost end of the slat portion, is configured to be higher than the height of the slat portion's crosspieces. With this configuration, because the guide portion is sloped, urine that runs down the guide portion easily reaches the outermost through-hole. Furthermore, because the height of the lower end of the guide portion is higher than the height of the crosspieces, urine that runs down the guide portion can be properly guided to the through-hole. As described above, the excretion container according to the present disclosure can properly guide urine to the through-hole, thereby suppressing the occurrence of urine pooling and suppressing the generation of urine odor. Furthermore, the excretion container according to the present disclosure can suppress the formation of urinary stones caused by urine pooling. By suppressing the formation of urinary stones, it is possible to prevent the deterioration of appearance due to the formation of urinary stones and reduce the burden of urinary stone removal.

[0008] When the device is installed horizontally, there does not need to be a horizontal portion between the lower end of the guide portion and the outermost through-hole. With this configuration, there is no portion (horizontal portion) where urine that has passed through the guide portion can remain, thereby more appropriately preventing urine pooling and the resulting formation of urinary stones.

[0009] The slatted portion may further have an inclined portion that slopes downward from the lower end of the guide portion toward the through-hole at the outermost end, and the inclination angle of the inclined portion may be greater than the inclination angle of the guide portion. With this configuration, urine that has passed through the guide portion gains more momentum due to the inclined portion with a larger inclination angle before reaching the through-hole, thereby more appropriately suppressing the occurrence of urine pooling and the formation of urinary stones caused by urine pooling.

[0010] The lower end of the guide portion may be continuous with the through-hole at the outermost end. By directly connecting the lower end of the guide portion with the through-hole, urine can be sent from the guide portion to the through-hole without passing through an area where urine can accumulate. This makes it possible to more appropriately prevent urine accumulation and the resulting formation of urinary stones.

[0011] When the toilet is installed horizontally, the height of the surfaces of the plurality of rungs may be higher for the rungs located on the outside in the short-side direction and lower for the rungs located in the center in the short-side direction. With this configuration, the outer rungs closer to the guide portion are higher and the inner rungs farther from the guide portion are lower, so that urine that reaches the inside can be reliably guided to the through-hole. In other words, the occurrence of urine pooling and the resulting formation of urinary stones can be more appropriately suppressed.

[0012] The crosspiece may have a convex shape at the center in the short direction. This configuration improves urine drainage at the crosspiece, thereby more appropriately suppressing the occurrence of urine pooling and the resulting formation of urinary stones.

[0013] The through-hole may be formed so that its shape widens from the middle to the bottom in the vertical direction. This configuration improves urine drainage at the bars, thereby more appropriately suppressing the occurrence of urine pooling and the resulting formation of urinary stones.

[0014] The height of the back surface of the bars may vary depending on the area. This configuration improves the drainage of urine that reaches the back surface of the bars, thereby more appropriately suppressing the formation of urine pools and urinary stones caused by urine pools. [Effects of the Invention]

[0015] According to the present disclosure, it is possible to provide an excrement container for a pet toilet that can prevent urine pooling. [Brief explanation of the drawings]

[0017] An excretion container according to an embodiment of the present disclosure will be described below with reference to the drawings. In each drawing, the same or corresponding parts are designated by the same reference numerals, and duplicated explanations will be omitted. The drawings are schematic, and the dimensional ratios may differ from those of the actual product. Note that in this embodiment, an example of an excretion container will be described as "an excretion container that divides the internal space of a pet system toilet into upper and lower sections and receives urine excreted by a pet," but is not limited to this. In other words, the excretion container is not limited to being one component of a pet system toilet, and may be configured to receive urine excreted by a pet in, for example, a single-layer toilet (specifically, a toilet that uses clumping sand, etc.).

[0018] FIG. 1 is a perspective view of a 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 pet cats. The pet system toilet 1 may be, for example, a system toilet suitable for keeping multiple large cats, with an excretion space approximately twice that of a typical system toilet. Specifically, the pet system toilet 1 may have a longitudinal length of approximately 70 cm, a lateral length of approximately 47 cm, and a height of approximately 28 cm. In the following description, the longitudinal direction may be referred to as the Y direction, the lateral direction as the X direction, and the height direction as the Z direction. Note that the pet system toilet 1 may also be a system toilet for the excretion of pets other than cats.

[0019] As shown in Fig. 1, the pet toilet system 1 includes an excretion 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 referred to as "up," and the direction of the lower container 3 as seen from the upper container 4 may be referred to as "down." Additionally, in the X direction (short side direction), the direction toward the opening 40 of the front wall portion 41 as seen from the rear wall portion 42 of the upper container 4 may be referred to as "front," and the direction toward the rear wall portion 42 as seen from the opening 40 may be referred to as "rear."

[0020] The excretion container 2 is a container that contains sand (not shown) that functions as litter and collects urine excreted by pets. The excretion container 2 also functions as a partition that divides the internal space of the pet system toilet 1 into an upper space (the space divided by the excretion container 2 and the upper container 4) and a lower space (the space divided by the excretion container 2 and the lower container 3). The excretion container 2 has a liquid-permeable bottom surface 21 and wall surfaces 22. Sand is a granular material that can absorb or pass through liquids such as urine. For example, the sand may be made of bentonite or water-repellent coated wood or paper that can cover feces and absorb liquid, or zeolite, silica gel, minerals, etc. that have deodorizing properties and are molded into approximately spherical shapes with a diameter of about 2 mm to 15 mm. Known sand may be used. Note that hardening sand may also be used. The sand is placed on the bottom surface 21. The excrement excreted by the pet passes through the sand, passes through the gaps in the bottom surface portion 21, which is composed of slat-like bars, and falls into the lower container 3 (more specifically, the tray 5 held by the lower container 3) located below the excrement container 2. The excrement container 2 is made of, for example, but is not limited to, a resin such as plastic. Details of the excrement container 2 will be described later.

[0021] The tray 5 is disposed below the waste container 2 and contains an absorbent sheet (not shown) that absorbs liquid (excrement) that has permeated the bottom surface 21. The tray 5 is formed with a tray handle 51 that allows the user to pull it out with their hands. The tray handle 51 may be formed not only on the front side of the tray 5 but also on the rear side. In this case, the tray 5 is symmetrical from front to back. Since the tray 5 is symmetrical from front to back and has the tray handle 51 on both the front and rear sides, the tray 5 can be pulled out via the tray handle 51 even when the tray 5 is reversed. The area of ​​the absorbent sheet that absorbs liquid is determined to some extent, but by reversing the tray 5, the orientation of the absorbent sheet can be changed, allowing the absorbent sheet to absorb liquid in an area different from the area that has already absorbed liquid. By reversing the tray 5 in this way, one absorbent sheet can be used to its full potential. The tray 5 is formed smaller than the lower container 3 so that it can be accommodated inside the lower container 3 and swing. 1, the tray 5 is accommodated in an area of ​​the lower container that is offset to one side in the Y direction. In this embodiment, the tray 5 is pulled out horizontally, but is not limited to this and may be pulled out obliquely upward, for example.

[0022] The lower container 3 is a container that holds the tray 5 and defines a lower space between it and the excreta container 2. The lower container 3 houses the tray 5 therein so that it can be pulled out and swung. The lower container 3 is configured to include a bottom surface 31 and wall surfaces 32, 33, 34, and 35. The bottom surface 31 is the portion that faces the installation surface on which the pet system toilet 1 is installed. The bottom surface 31 is formed in a rectangular shape when viewed from above.

[0023] The wall surface 32 is a portion formed to rise upward from the front end of the bottom surface portion 31. An opening 320 for pulling out the tray 5 is formed in the wall surface 32. The wall surface 33 is a portion formed to rise upward from the rear end of the bottom surface portion 31. The wall surfaces 34 and 35 are portions formed to rise upward from both ends of the bottom surface portion 31 in the Y direction. A recess 400 is formed in the lower part of the center of the wall surfaces 34 and 35 in the X direction to be gripped when carrying the device. The wall surfaces 32, 33, 34, and 35 are formed continuously, and the entire periphery of the bottom surface portion 31 is surrounded by the wall surfaces 32, 33, 34, and 35. The wall surfaces 22 (more specifically, a first side wall 221, a second side wall 222, a third side wall 223, and a fourth side wall 224 (see FIG. 2) described below) of the excrement container 2 are fitted to 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 a container that is disposed above the excretion container 2 and defines an upper section between it and the excretion container 2. The upper container 4 has an opening 40 through which pets can enter and exit. As shown in FIG. 1, the upper container 4 includes a front wall 41, a rear wall 42, and a pair of side walls 43, 44. In this embodiment, the front wall 41, the rear wall 42, and the pair of side walls 43, 44 are integrally (continuously) formed. The upper container 4 does not have a bottom surface, and is open in the vertical direction.

[0025] The front wall 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 in a predetermined position in the Y direction on the front wall 41. As will be described later, a slatted portion 210 is provided in a position offset in one direction in the Y direction from the center of the bottom surface 21 of the excreta container 2. The slatted portion 210 has a plurality of through-holes formed therein, and sand (litter) is placed in the slatted portion 210. By forming the opening 40 on the front wall 41 on the opposite side (opposite side in the Y direction) from the offset position of the slatted portion 210, a structure can be created in which sand is collected on the far side as viewed from the pet entrance (opening 40), and the pet can be naturally guided to the far side.

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

[0027] Next, an example of the excretion container 2 will be described in detail with reference to FIGS.

[0028] Fig. 2 is a plan view of the excretion container 2 included in the pet toilet system 1. Fig. 3 is a bottom view of the excretion container 2. Fig. 4 is a front view of the excretion container 2. Figs. 5 and 6 are perspective views of the excretion container 2. As shown in Figs. 2 to 6, the excretion container 2 has 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 portion 21. The wall surface 22 has a first side wall 221 and a second side wall 222 formed along the Y direction and facing each other, and a third side wall 223 and a fourth side wall 224 formed along the X direction and facing each other. The first side wall 221 is fitted to the upper end of the wall surface 32 (see FIG. 1) of the lower container 3. The second side wall 222 is fitted to the upper end of the wall surface 33 (see FIG. 1) of the lower container 3. The third side wall 223 is fitted to the upper end of the wall surface 34 (see FIG. 1) of the lower container 3. The fourth side wall 224 is fitted to the upper end of the wall surface 35 (see FIG. 1) of the lower container 3.

[0030] The bottom surface portion 21 is a plate-like member that is generally rectangular in plan view. The bottom surface portion 21 has a slat portion 210 and an inclined surface portion 211.

[0031] The slat portion 210 is a portion in which a plurality of through holes 215 are formed and in which sand (litter) is placed. In the slat portion 210, crosspieces are formed in a slat-like shape, and regular gaps (through holes 215) are formed between the crosspieces. As shown in FIG. 2 , the slat portion 210 is partitioned into a generally rectangular shape in a 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 slat portion 210 is provided at a position offset in one direction in the Y direction from the center of the bottom surface portion 21; specifically, it is provided at a position offset in a direction approaching the fourth side wall 224. Details of the slat portion 210 will be described later.

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

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

[0034] As shown in FIG. 8 , the first portion 211a of the inclined surface portion 211, which serves as a guide portion, is inclined downward toward the outermost through-hole 215 of the slat 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 crosspiece 250 (specifically, the highest portion of the surface 250a). When set horizontally, there is no horizontal portion between the lower end 211u of the first portion 211a, which serves as a guide portion, and the outermost through-hole 215. The slat portion 210 further has an inclined portion 260 that is inclined downward from the lower end 211u of the first portion 211a, which serves as a 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, which serves as a guide portion.

[0035] 8, in a horizontally installed state, the height of the surfaces 250a of the multiple crosspieces 250 may be higher as the crosspieces 250 are arranged on the outer side in the X direction and lower as the crosspieces 250 are arranged on the inner side (center). The crosspieces 250 may have a convex shape at the center in the X direction.

[0036] The through-hole 215 is formed so that its shape widens downward in the Z direction. The through-hole 215 is formed so that its shape widens from at least a middle portion in the Z direction toward the bottom, and may be formed so that its shape widens from the top to the bottom as shown in FIG.

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

[0038] As shown in FIG. 10 , the third portion 211c of the inclined surface portion 211, which serves as a guide portion, is inclined downward toward the outermost through-hole 215 of the slat 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 crosspiece 270 (specifically, the highest portion of the surface 270a). When set horizontally, there is no horizontal portion between the lower end 211v of the third portion 211c, which serves as a guide portion, and the outermost through-hole 215. The slat portion 210 further has an inclined portion 280 that inclines downward from the lower end 211v of the third portion 211c, which serves as a guide portion, toward the outermost through-hole 215. The inclination angle of the inclined portion 280 is greater than the inclination angle of the third portion 211c, which serves as a guide portion. The crosspiece 270 may have a convex central portion in the Y direction.

[0039] FIG. 11 is a diagram illustrating the suppression of urine pooling in the configuration according to this embodiment compared to a comparative example. In the configuration of the comparative example shown in FIG. 11(a), the tip of the guide portion 501, which slopes downward toward the through-hole 215, is continuous with the horizontal portion 502. In this case, urine UR that passes through the guide portion 501 accumulates in the horizontal portion 502, which can cause problems with urine pooling and urinary stones. In contrast, in the configuration according to this embodiment shown in FIG. 1(b), there is no horizontal portion between the lower end of the guide portion 300, which slopes downward toward the through-hole 215, and the through-hole 215. This prevents urine pooling and urinary stones from forming. Note that the configuration shown in FIG. 11(b) differs from the first portion 211a and the third portion 211c described above in that the lower end of the guide portion 300 is directly continuous with the through-hole 215.

[0040] FIG. 12 is an enlarged view of region XII shown in FIG. 3, i.e., a partial enlarged view of the back (bottom) side of the slat unit 210. As shown in FIGS. 3 and 12, the slat unit 210 is formed in a substantially rectangular shape when viewed from the back side. The slat unit 210 has a crosspiece 200 in which a plurality of crosspieces 250 (first crosspieces) extending in the Y direction (longitudinal direction) and a plurality of crosspieces 270 extending in the X direction (transverse direction) are arranged in a lattice pattern, and a plurality of through holes 215 formed so as to be surrounded by the crosspieces 250, 270. Here, crosspieces 250E, which are crosspieces 250 at both ends in the X direction, are formed to have a thinner thickness in the X direction than the other crosspieces 250. Specifically, the thickness in the X direction of crosspieces 250E, which are crosspieces 250 at both ends in the X direction, may be approximately 0.1 to 0.9 times the thickness in the X direction of the other crosspieces 250. For example, the thickness in the X direction of the crosspieces 250E, which are the crosspieces 250 at both ends in the X direction, may be about 1.0 to 1.6 mm, and the thickness in the X direction of the other crosspieces 250 may be about 1.5 to 2.5 mm.

[0041] Furthermore, crosspieces 270E, which are crosspieces 270 at both ends in the Y direction, are formed to have a thinner thickness in the Y direction than the other crosspieces 270. Specifically, the thickness in the Y direction of crosspieces 270E, which are crosspieces 270 at both ends in the Y direction, may be approximately 0.1 to 0.9 times the thickness in the Y direction of the other crosspieces 270. For example, the thickness in the Y direction of crosspieces 270E, which are crosspieces 270 at both ends in the Y direction, may be approximately 1.0 to 1.6 mm, and the thickness in the Y direction of the other crosspieces 270 may be approximately 1.5 to 2.5 mm.

[0042] Fig. 13 is a perspective view of the back surface of the slat unit 210 as viewed from above in the X direction. Fig. 14 is an end view of the slat unit 210 (as viewed from the X direction). As shown in Figs. 13 and 14, the back surface of the crosspiece 250 (first crosspiece) has different protrusion amounts in each region in the Y direction (the height varies depending on the region). The back surface of the crosspiece 250 is formed in an arch shape along the Y direction so that the protrusion amount increases as it approaches a first intersection 291 where the crosspiece 250 intersects with one of the crosspieces 270 (second crosspieces) and decreases as it moves away from the first intersection 291.

[0043] Fig. 15 is a perspective view of the back surface side of the slat portion 210 as seen from above in the Y direction. Fig. 16 is a cross-sectional view showing a cross section taken along line XVI-XVI shown in Fig. 15. As shown in Figs. 15 and 16, the back surface of the crosspiece 270 (second crosspiece) has different protrusion amounts in each region in the X direction (the height varies depending on the region). The back surface of the crosspiece 270 is formed in an arch shape along the X direction so that the protrusion amount increases as it approaches a second intersection 292 where the crosspiece 270 intersects with one of the crosspieces 250 (first crosspiece), and decreases as it moves away from the second intersection 292.

[0044] Next, the effects of the excreta 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 approximately rectangular in plan view and that receives urine excreted by pets. The bottom surface 21 has a slatted portion 210 having a plurality of through holes 215 aligned in the short side direction (X direction) and a plurality of crosspieces 250 provided between adjacent through holes 215, and a first portion 211a and a second portion 211b that function as guide portions provided around the slatted portion 210 so as to surround the slatted portion 210. The first portion 211a and the second portion 211b are inclined downward toward the outermost through hole 215 in the X direction of the slatted portion 210, and when placed horizontally, the height of the lower ends 211u of the first portion 211a and the second portion 211b is higher than the height of the surfaces 250a of the crosspieces 250.

[0046] In the excretion container 2 according to this embodiment, the height of the lower ends 211u of the first and second portions 211a and 211b, which function as guide portions inclined downward toward the through-holes 215 at the outermost ends of the slatted portion 210, is configured to be higher than the height of the surfaces 250a of the crosspieces 250 of the slatted portion 210. With this configuration, because the first and second portions 211a and 211b are inclined, urine that has flowed down the first and second portions 211a and 211b easily reaches the through-holes 215 at the outermost ends. Furthermore, because the height of the lower ends 211u of the first and second portions 211a and 211b is higher than the height of the surfaces 250a of the crosspieces 250, urine that has flowed down the first and second portions 211a and 211b can appropriately reach the through-holes 215. As described above, the excretion container 2 according to this embodiment can appropriately guide urine to the through-holes 215, thereby preventing urine from pooling and suppressing 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 appearance from being deteriorated due to the formation of urinary stones and reduce the burden of removing the urinary stones.

[0047] In a state where the container is installed horizontally, there does not need to be a horizontal portion between the lower ends 211u of the first portion 211a and the second portion 211b and the outermost through-holes 215. With this configuration, there is no portion (horizontal portion) where urine that has passed through the first portion 211a and the second portion 211b accumulates, so that it is possible to more appropriately prevent urine pooling and the formation of urinary stones caused by urine pooling.

[0048] The slatted portion 210 further has an inclined portion 260 that is inclined downward from the lower end 211u of the first portion 211a and the second portion 211b toward the outermost through-hole 215, and the inclination angle of the inclined portion 260 may be larger than the inclination angle of the first portion 211a and the second portion 211b. With this configuration, urine that has passed through the first portion 211a and the second portion 211b is further accelerated by the inclined portion 260, which has a larger inclination angle, before reaching the through-hole 215, thereby more appropriately suppressing the formation of urine pools and urinary stones caused by urine pools.

[0049] The lower ends 211u of the first portion 211a and the second portion 211b may be continuous with the outermost through-hole 215. By directly connecting the lower ends 211u of the first portion 211a and the second portion 211b to the through-hole 215, urine can be sent from the first portion 211a and the second portion 211b to the through-hole 215 without an intervening portion where urine can accumulate. This makes it possible to more appropriately prevent urine accumulation and the formation of urinary stones due to urine accumulation.

[0050] In a horizontally installed state, the height of the surfaces 250a of the multiple crosspieces 250 may be higher for the crosspieces 250 located on the outer side in the short-side direction (X direction) and lower for the crosspieces 250 located in the center in the X direction. With this configuration, the outer crosspieces 250 closer to the first portion 211a and the second portion 211b are higher and the inner crosspieces 250 farther from the first portion 211a and the second portion 211b are lower, so that urine that reaches the inside can reliably reach the through-hole 215. In other words, the occurrence of urine pooling and the formation of urinary stones due to urine pooling can be more appropriately suppressed.

[0051] The crosspiece 250 may have a convex shape at the center in the short-side direction (X direction). This configuration improves urine drainage at the crosspiece 250, thereby more appropriately suppressing the occurrence of urine pooling and the formation of urinary stones caused by urine pooling.

[0052] The through-hole 215 may be formed so that the hole shape widens from the middle to the bottom in the vertical direction. With this configuration, the crosspiece 250 can be more efficiently drained of urine, thereby more appropriately suppressing the occurrence of urine pooling and the formation of urinary stones caused by urine pooling.

[0053] The height of the rear surface of the crosspiece 250 may vary depending on the region. With this configuration, urine that reaches the rear surface of the crosspiece 250 is more easily drained, thereby more appropriately suppressing the formation of urine pools and urinary stones caused by urine pools.

[0054] The excretion container 2 according to this embodiment is an excretion container having a bottom surface 21 for receiving urine excreted by a pet, and the bottom surface 21 has a slat portion 210 that is approximately rectangular when viewed from the back side, and the slat portion 210 has a slat 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 lateral direction (X direction) are arranged in a lattice pattern, and a plurality of through holes 215 formed so as to be surrounded by each slat 250, 270, and the slats 250E at both ends in the lateral direction (X direction) may be formed to be thinner in the X direction than the other slats 250.

[0055] In the excretion container 2 according to this embodiment, the thickness of the crosspieces 250E at both ends in the X direction of the slatted portion 210 is thinner than that of the other crosspieces 250. The crosspieces 250 other than those at both ends in the X direction are adjacent to the adjacent crosspieces 250 on both sides via the crosspieces 270, which facilitates urine collection and makes it easier for urine that has reached a certain weight to fall. On the other hand, the crosspieces 250E at both ends in the X direction are adjacent to only one crosspiece 250, which makes it difficult for urine to collect. This makes it easier for urine to pool and form urinary stones. In this regard, the crosspieces 250E at both ends in the X direction are thinner than the other crosspieces 250, which facilitates urine to fall. Therefore, urine can be appropriately caused to fall even on the crosspieces 250E at both ends in the X direction, where urine is relatively difficult to collect. This appropriately prevents urine from pooling and forming urinary stones at the crosspieces 250E at both ends in the X direction.

[0056] The crosspieces 270E at both ends in the longitudinal direction (Y direction) may be formed to be thinner in the Y direction than the other crosspieces 270. With this configuration, the crosspieces 270E at both ends in the Y direction are thinner than the other crosspieces 270, which makes it easier for urine to fall, and therefore urine can fall appropriately even on the crosspieces 270 at both ends in the Y direction where urine is relatively difficult to collect. This makes it possible to appropriately prevent urine from pooling at the crosspieces 270 at both ends in the Y direction and causing urinary stones.

[0057] The rear surface of the crosspiece 250 may have different protrusion amounts in the Y direction between the respective regions. In this way, by having the protrusion amounts of the rear surface of the crosspiece 250 differ between the respective regions in the Y direction, urine is collected in the areas with larger protrusion amounts, which encourages the urine to fall, and appropriately suppresses the formation of urinary stones.

[0058] The back surface of the crosspiece 250 may be formed in an arch shape along the Y direction so that the amount of protrusion increases as it approaches a first intersection 291 where the crosspiece 250 intersects with one of the crosspieces 270, and decreases as it moves away from the first intersection 291. In this way, by increasing the amount of protrusion at the intersection where urine is particularly likely to collect, it is possible to more appropriately encourage urine to fall and appropriately prevent the formation of urinary stones.

[0059] The rear surface of the crosspiece 270 may have different protrusion amounts in the X direction between the respective regions. In this way, by having the protrusion amounts of the rear surface of the crosspiece 270 differ between the respective regions in the X direction, urine is collected in the areas with larger protrusion amounts, which encourages urine to fall, and can appropriately suppress the formation of urinary stones.

[0060] The back surface of the crosspiece 270 may be formed in an arch shape along the X direction so that the amount of protrusion increases as it approaches a second intersection 292 where the crosspiece 270 intersects with one of the crosspieces 250, and decreases as it moves away from the second intersection 292. In this way, by increasing the amount of protrusion at the intersection where urine is particularly likely to collect, it is possible to more appropriately encourage urine to fall and appropriately prevent the formation of urinary stones.
