[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2003-180182 Summary of the Invention [Problem to be solved by the invention]

[0004] In the animal litter box described above, the partition member is installed at a predetermined position within the main container, so the height of the partition member is constant. However, the appropriate height of the partition member varies depending on the size of the animal using the animal litter box. Therefore, in conventional animal litter boxes, the position of the partition member was sometimes too high or too low.

[0005] The present invention has been made in view of the above-mentioned problems, and has an object to provide an animal litter box in which the height of a partition member is adjustable. [Means for solving the problem]

[0006] The animal litter box according to the present invention comprises a main container having a bottom portion and a side portion, and a partition member having a through hole for allowing urine to pass through and dividing the interior of the main container into upper and lower portions, and the height of the partition member is variable.

[0007] In this animal litter box, the height of the partition member is adjustable, so that the height of the partition member can be adjusted to suit the size of the animal using the animal litter box. [Effects of the Invention]

[0008] According to the present invention, an animal litter box is realized in which the height of the partition member can be adjusted. [Brief explanation of the drawings]

[0010] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the description of the drawings, the same elements are given the same reference numerals and redundant description will be omitted.

[0011] FIG. 1 is an end view showing one embodiment of an animal litter box according to the present invention. The configuration of the animal litter box 1 will be outlined with reference to this figure. The animal litter box 1 comprises a main container 10, a partition member 20, a plurality of granular materials 30, an absorbent sheet 40, and a drawer section 50. The main container 10 is box-shaped and has a bottom section 10a and side sections 10b. The outer shape of the main container 10 is a roughly rectangular parallelepiped. The main container 10 can be made of plastic, such as polypropylene or polyethylene.

[0012] The container body 10 has a support portion 12 (first support portion), a support portion 14 (second support portion), and a support portion 16 (third support portion). Each of the support portions 12, 14, and 16 protrudes from the side surface portion 10b toward the inside of the container body 10 and is capable of supporting the partition member 20 from below. Each of the support portions 12, 14, and 16 supports the partition member 20 horizontally. Each of the support portions 12, 14, and 16 is formed, for example, by a protrusion or projection. Each of the support portions 12, 14, and 16 may be molded integrally with the side surface portion 10b, or may be molded separately from the side surface portion 10b and then attached to the side surface portion 10b.

[0013] Support portion 12, support portion 14, and support portion 16 are provided at different positions in the height direction of main container 10 (which is the same as the up-and-down direction in FIG. 1). Specifically, support portion 14 is provided at a higher position than support portion 12. Furthermore, support portion 16 is provided at a higher position than support portion 14.

[0014] The partition member 20 is plate-shaped and is disposed parallel to the bottom surface portion 10a. The partition member 20 is made of a single plate of uniform thickness. The partition member 20 has through-holes 22 that allow urine to pass through. The through-holes 22 allow urine to pass through but do not allow the granular material 30 to pass through. The partition member 20 is disposed at a position spaced apart from both the upper end of the main container 10 (side surface portion 10b) and the absorbent sheet 40. This allows the partition member 20 to divide the interior of the main container 10 into upper and lower spaces. That is, the interior of the main container 10 is divided by the partition member 20 into an upper space S1 and a lower space S2. The upper space S1 is located above the partition member 20 and is a space in which a plurality of granular materials 30 are placed. The lower space S2 is located below the partition member 20 and is a space in which urine that has passed through the through-holes 22 collects. The partition member 20 is detachable from the main container 10. The material of the partition member 20 may be, for example, a plastic such as polypropylene or polyethylene.

[0015] The partition member 20 is placed on the support portion 12, the support portion 14, or the support portion 16. The upper surface (the surface on which the partition member 20 is placed) of each of the supports 12, 14, and 16 is horizontal. FIG. 1 shows the partition member 20 placed on the support portion 14. When the partition member 20 is placed on the support portion 12 as shown in FIG. 2, the height of the partition member 20 (the distance from the floor surface on which the main container 10 is placed to the upper surface of the partition member 20) is lower than when the partition member 20 is placed on the support portion 14. On the other hand, when the partition member 20 is placed on the support portion 16 as shown in FIG. 3, the height of the partition member 20 is higher than when the partition member 20 is placed on the support portion 14. In this way, the height of the partition member 20 is variable. The animal litter box 1 is configured so that the height of the partition member 20 can be changed in stages. The difference d1 (see FIG. 1) between the maximum height of partition member 20 (the height when placed on support part 16) and the minimum height (the height when placed on support part 12) is preferably 5 cm or more, and more preferably 10 cm or more. Difference d1 is equal to the distance from the top surface of support part 12 to the top surface of support part 16 in the height direction of main container 10.

[0016] A plurality of granular materials 30 for treating excrement (urine) are laid on the partition member 20. Each granular material 30 is granular. Examples of the shape of such granular materials include a sphere, a cylinder, and an ellipsoid. The particle size of each granular material 30 is, for example, 5 mm or more and 20 mm or less. Here, the particle size of a granular material 30 is defined as the diameter of the smallest sphere that can contain the granular material 30. When the animal litter box 1 is in use, the granular materials 30 directly receive excreted urine.

[0017] The granular material 30 is hydrophobic. That is, the granular material 30 has the property of not absorbing any liquids, such as urine, or absorbing very little if any. For the granular material 30 to be considered hydrophobic, it is necessary for the liquid passage rate, as measured by the following test, to be 60% or more. First, 50 g of the granular material 30 (sample) is placed on a sieve with an inner diameter of 10 cm and a mesh size of 1 mm. An empty beaker is placed below the sieve. Then, 30 ml of water is dripped onto the sample over 10 seconds using a syringe (Terumo 60 ml syringe) with an inner diameter of 3 cm and an inner diameter of 4 mm at the tip. After leaving it for 1 minute, the amount of water in the beaker is measured. The liquid passage rate is the ratio of the measured amount of water to the amount of water dripped (30 ml). That is, if the amount of water in the beaker is 18 ml or more, the liquid passage rate is 60% or more, and the granular material 30 can be considered to be hydrophobic.

[0018] Each granule 30 is preferably made primarily of an organic material. Here, the "main material" of the granule 30 refers to the material that accounts for the largest weight percentage of the granule 30 among one or more materials that make up the granule 30. Examples of such organic materials include paper, used tea leaves, plastics, and soybean lees. Each granule 30 may be made solely of organic materials, or may be made of organic and inorganic materials.

[0019] Papers refer to materials primarily composed of pulp. Examples of papers include ordinary paper, PVC wallpaper fractions, photographic paper, release paper, fluff pulp, papermaking sludge, and pulp sludge. PVC wallpaper fractions are obtained by removing a portion of the polyvinyl chloride from PVC wallpaper containing paper and PVC. Examples of plastics include ordinary plastics, aluminum vapor-deposited film, and disposable diaper fractions (plastics obtained by classifying disposable diapers). Dried bean curd refuse is preferred. These materials may or may not be subjected to a hydrophobic (water-repellent) treatment.

[0020] The granular material 30 may be made of only one material, or may be made of two or more materials. In the former case, the material making up the granular material 30 is only the main material described above. In the latter case, the granular material 30 is made up of a mixture of the main material and other materials. Examples of other materials include gypsum or baking soda. Adding gypsum or baking soda can increase the hydrophobicity of the granular material 30. The amount of gypsum or baking soda is, for example, 5% by weight or more and less than 50% by weight of the entire granular material 30.

[0021] The granules 30 can be manufactured, for example, by the following method. First, the material to be granulated (the material that constitutes the granules 30) is granulated using a granulation device to form a granule that will become the granules 30. An extrusion granulator, for example, can be used as the granulation device. The granules may be subjected to a hydrophobic treatment, if necessary. The hydrophobic treatment can be performed, for example, by coating the surface of the granules with a hydrophobic agent (water repellent). If the hydrophobic treatment is not performed, it is preferable to minimize the formation of gaps within the granules by increasing the pressure applied to the material to be granulated during granulation. This is because such gaps can serve as a path for liquids such as urine to penetrate into the granules 30. Prior to granulation, the material to be granulated may be subjected to pretreatment such as pulverization, kneading, or hydration, as needed. After granulation, posttreatment such as sieving (sizing) or drying may be performed as needed.

[0022] A water-absorbent sheet 40 is disposed below the partition member 20. The water-absorbent sheet 40 absorbs urine that has passed through the through-holes 22 of the partition member 20. That is, the urine that has passed through the through-holes 22 is absorbed by the water-absorbent sheet 40 and accumulates in the lower space S2.

[0023] The drawer 50 can be inserted into and removed from the main container 10 through an opening 18 formed in the side surface 10b. The drawer 50 houses the absorbent sheet 40. That is, the absorbent sheet 40 is disposed inside the main container 10 while housed in the drawer 50. The drawer 50 can be made of a plastic such as polypropylene or polyethylene.

[0024] When the animal litter box 1 is in use, urine excreted on the granules 30 flows downward through the gaps between the granules 30. The urine moves from the upper space S1 to the lower space S2 through the through-holes 22 of the partition member 20 and is absorbed by the absorbent sheet 40.

[0025] The configuration of each part of the animal litter box 1 will be described in detail below with reference to Figs. 4 to 10. Figs. 4 and 5 are an end view and a front view, respectively, of the main container 10. An opening 18 for inserting and removing the drawer 50 is formed in the side surface 10b of the main container 10. The opening 18 is located near the bottom surface 10a and has a horizontally long rectangular shape. The length of the opening 18 in the horizontal direction (left-right direction in Fig. 5) is approximately equal to the width (inner dimension) of the main container 10, and is, for example, 20 cm to 40 cm. The length of the opening 18 in the vertical direction (top-bottom direction in Fig. 5) is, for example, 2 cm to 5 cm.

[0026] 6 to 8 are plan views showing the main container body 10. However, in FIG. 6, the support portion 14 and the support portion 16 are not shown. In FIG. 7, the support portion 12 and the support portion 16 are not shown. In addition, in FIG. 8, the support portion 12 and the support portion 14 are not shown. As can be seen from FIG. 6, the support portion 12 is provided over the entire inner periphery of the side portion 10b in plan view. The support portion 12 consists of a ridge provided in an annular shape along the inner periphery of the side portion 10b. The inner periphery of the side portion 10b has a substantially rectangular shape in plan view.

[0027] As can be seen from Figure 7, the support portions 14 are provided only on a portion of the inner periphery of the side surface portion 10b in plan view. In plan view, the length of the portion of the inner periphery of the side surface portion 10b where the support portions 14 are provided is preferably 1 / 2 or less of the entire length of the inner periphery. In plan view, the support portions 14 are provided only on two opposing sides of the four sides of the inner periphery of the side surface portion 10b. The support portions 14 consist of ridges extending along the two sides.

[0028] As can be seen from FIG. 8, the support portion 16 is provided only on a portion of the inner periphery of the side portion 10b in plan view. In plan view, the length of the portion of the inner periphery of the side portion 10b where the support portion 16 is provided is preferably 1 / 2 or less of the entire length of the inner periphery. In plan view, the support portion 16 is provided only on two opposing sides of the four sides of the inner periphery of the side portion 10b. The support portion 16 consists of protrusions extending along the two sides. In plan view, the support portion 16 is provided in the same position as the support portion 14. Therefore, the support portion 14 and the support portion 16 overlap each other in plan view.

[0029] The protruding length p1 of the support portion 12 (see FIG. 6) is, for example, 10 mm or more and 20 mm or less. Here, the protruding length of the support portion 12 is the length in a direction perpendicular to the inner surface of the side surface portion 10b on which the support portion 12 is provided. The protruding length p2 of the support portion 14 (see FIG. 7) is smaller than the protruding length p1 of the support portion 12. Similarly, the protruding length p3 of the support portion 16 (see FIG. 8) is smaller than the protruding length p1 of the support portion 12. Each of the protruding lengths p2 and p3 is, for example, 5 mm or more and 15 mm or less. The protruding length p2 and the protruding length p3 may be equal to each other or may be different from each other.

[0030] 9 is a plan view showing the partition member 20. The partition member 20 can be disposed in the main container 10 with its entire periphery separated from the side surface portion 10b. The planar shape of the partition member 20 is approximately rectangular. The through holes 22 are arranged two-dimensionally in the partition member 20. In this embodiment, the planar shape of each through hole 22 is circular. The diameter of each through hole 22 is, for example, 2 mm or more and 4 mm or less.

[0031] 10 is a perspective view showing the drawer unit 50. The drawer unit 50 has a bottom plate 50a, a front plate 50b, a tip plate 50c, and a pair of side plates 50d. The size of the bottom plate 50a is approximately equal to the size of the bottom surface 10a of the main container body 10. The front plate 50b has approximately the same shape and size as the opening 18. A handle 52 is attached to the front plate 50b.

[0032] The effects of the animal litter box 1 will now be explained. In the animal litter box 1, the height of the partition member 20 is variable. In this case, the height of the partition member 20 can be adjusted by changing the height of the partition member 20 to match the size of the animal using the animal litter box 1. Therefore, an animal litter box 1 has been realized in which the height of the partition member 20 can be adjusted.

[0033] Incidentally, lowering the position of the partition member 20 deepens the upper space S1, which is advantageous for preventing the granular material 30 from scattering outside the main container 10. However, on the other hand, a deep upper space S1 makes it difficult for small animals to enter and exit the main container 10. Therefore, from the perspective of balancing the difficulty of the granular material 30 scattering and the ease of animal entry and exit, the appropriate height of the partition member 20 varies depending on the size of the animal using the animal litter box 1. Specifically, it is preferable to position the partition member 20 relatively low for relatively large animals and relatively high for relatively small animals. According to this embodiment, the height of the partition member 20 can be adjusted according to the size of the animal.

[0034] To flexibly accommodate animals of various sizes, it is advantageous for the height of the partition member 20 to vary widely. From this perspective, the difference between the maximum and minimum heights of the partition member 20 is preferably 5 cm or more, and more preferably 10 cm or more. On the other hand, if the height of the partition member 20 varies too widely, it may be difficult to ensure sufficient space within the main container 10 for the partition member 20 to be placed therein. From this perspective, it is preferable for the difference between the maximum and minimum heights of the partition member 20 to be 20 cm or less.

[0035] The animal litter box 1 is configured so that the height of the partition member 20 changes in stages. This configuration in which the height of the partition member 20 changes in stages can be achieved with a relatively simple mechanism. In fact, in the animal litter box 1, a configuration in which the height of the partition member 20 can be changed in stages is achieved with a simple mechanism in which multiple support parts (support part 12 and support part 14) are provided at different positions in the height direction of the main container 10.

[0036] The main container 10 has a support part 16 in addition to the support parts 12 and 14. This makes it possible to adjust the height of the partition member 20 in more stages than when only the support parts 12 and 14 are provided. However, providing the main container 10 with the support part 16 is not essential.

[0037] The support portion 12 is provided over the entire inner periphery of the side surface portion 10b in plan view, which makes it easier to prevent the partition member 20 from dropping below the support portion 12.

[0038] In plan view, the support portions 14 are provided only on a part of the inner periphery of the side surface portion 10b. In this case, the partition member 20 can be moved over the support portions 14 more smoothly than when the support portions 14 are provided on the entire inner periphery of the side surface portion 10b. This makes it easier to adjust the height of the partition member 20 (for example, to switch from a state in which the partition member 20 is placed on the support portions 14 to a state in which the partition member 20 is placed on the support portions 12).

[0039] From the viewpoint of smooth movement of the partition member 20, it is preferable that the length of the portion of the inner periphery of the side surface portion 10b where the support portion 14 is provided is equal to or less than half the length of the entire inner periphery.

[0040] In plan view, the support portions 16 are provided only on a part of the inner periphery of the side surface portion 10b. In this case, the partition member 20 can be moved over the support portions 16 more smoothly than when the support portions 16 are provided on the entire inner periphery of the side surface portion 10b. This makes it easier to adjust the height of the partition member 20 (for example, to switch from a state in which the partition member 20 is placed on the support portions 14 to a state in which the partition member 20 is placed on the support portions 16).

[0041] From the viewpoint of smooth movement of the partition member 20, it is preferable that the length of the portion of the inner periphery of the side surface portion 10b where the support portion 16 is provided is equal to or less than half the length of the entire inner periphery.

[0042] In plan view, the support portions 14 are provided only on two opposing sides of the four sides of the inner periphery of the side surface portion 10b. In this case, since there are no support portions 14 on the remaining two sides, the partition member 20 can move over the support portions 14 particularly smoothly.

[0043] In plan view, the support portions 16 are provided only on two opposing sides of the four sides of the inner periphery of the side surface portion 10b. In this case, since there are no support portions 16 on the remaining two sides, the partition member 20 can move over the support portions 16 particularly smoothly.

[0044] The protruding length of the support part 14 is smaller than the protruding length of the support part 12. Making the protruding length of the support part 14 smaller in this way is advantageous for smooth movement of the partition member 20 beyond the support part 14. On the other hand, making the protruding length of the support part 12 larger is advantageous for preventing the partition member 20 from dropping below the support part 12.

[0045] The protruding length of the support portion 16 is smaller than the protruding length of the support portion 12. Making the protruding length of the support portion 16 smaller in this manner is advantageous for allowing the partition member 20 to move smoothly beyond the support portion 16.

[0046] In a plan view, the support portion 16 is provided at the same position as the support portion 14. In this case, if the partition member 20 is tilted in the same way as when moving the partition member 20 past the support portion 14, the partition member 20 can be moved past the support portion 16. This also contributes to facilitating the adjustment of the height of the partition member 20.

[0047] The partition member 20 has a plate shape. In this case, the partition member 20 can be tilted to avoid the support portions 14 and 16, which is advantageous in facilitating the movement of the partition member 20 over the support portions 14 and / or 16.

[0048] The partition member 20 can be disposed in the main container 10 with its entire periphery spaced apart from the side surface 10b. By providing a margin between the partition member 20 and the side surface 10b in this manner, the partition member 20 can be moved smoothly when adjusting the height.

[0049] Each granule 30 is hydrophobic. In this case, most of the urine excreted on the granules 30 passes through the gaps between the granules 30 and reaches the partition member 20. The urine that reaches the partition member 20 moves into the lower space S2 through the through-holes 22. By collecting the urine in the lower space S2 in this way, it is possible to prevent the bad odor from the urine from leaking out of the main container 10.

[0050] When each granule 30 is made primarily of organic matter, it is possible to obtain a granule 30 that is suitable for incineration. In this case, it is easier to dispose of the used granule 30 as combustible waste, improving convenience for users (such as animal owners). In particular, when each granule 30 is made solely of organic matter, it is possible to obtain a granule 30 that is even more suitable for incineration.

[0051] A water-absorbent sheet 40 is disposed below the partition member 20. This allows urine that has accumulated in the lower space S2 to be trapped within the water-absorbent sheet 40. This reduces the occurrence of bad odors from the urine.

[0052] A drawer section 50 is provided that can be inserted into and removed from the main container 10. This allows the used water-absorbent sheet 40 to be easily replaced with a new one.

[0053] The present invention is not limited to the above embodiment, and various modifications are possible. In the above embodiment, the support portion 12 is provided on the entire inner periphery of the side surface portion 10b in a plan view. However, the support portion 12 may be provided on only a part of the inner periphery of the side surface portion 10b in a plan view.

[0054] In the above embodiment, the support portion 14 is provided only on a part of the inner periphery of the side surface portion 10b in a plan view. However, the support portion 14 may be provided on the entire inner periphery of the side surface portion 10b in a plan view. The same applies to the support portion 16.

[0055] In the above embodiment, the protruding length of support portion 14 is smaller than the protruding length of support portion 12. However, the protruding length of support portion 14 may be equal to or greater than the protruding length of support portion 12. The same applies to the protruding length of support portion 16.

[0056] In the above embodiment, the planar shape of the through-hole 22 is circular. However, the planar shape of the through-hole 22 may be any shape, such as an ellipse or a polygon such as a rectangle.

[0057] In the above embodiment, the case where the drawer section 50 is provided has been exemplified. However, providing the drawer section 50 is not essential. When the drawer section 50 is not provided, the water-absorbent sheet 40 is disposed directly on the bottom surface section 10a. In that case, naturally, the opening 18 is not provided in the side surface section 10b.

[0058] In the above embodiment, an example has been given in which the absorbent sheet 40 is provided in the main container 10. However, it is not essential to provide the absorbent sheet 40 in the main container 10. If the absorbent sheet 40 is not provided, the drawer section 50 will not be provided either.
