Description

The present invention relates to an animal litter box.

As a conventional animal toilet, there is one described in Patent Document 1, for example. The animal toilet described in this document includes a main body (tray) for receiving excreted urine, and a partition (screen) that divides the internal space of the main body into an upper space and a lower space. A through hole through which urine passes is formed in the partition. A plurality of granules having low water absorption are laid in the upper space (above the partition). A water absorbent sheet is arranged in the lower space. Urine excreted into the upper space of the main body passes between the particles and through the through holes of the partition, and then is absorbed by the water absorbent sheet in the lower space.

Japanese Patent Application Publication No. 2003-180182

However, in the above-mentioned animal litter box, the through hole may be blocked by the granular material laid in the upper space. When the through-hole is blocked in this way, it becomes difficult for urine to pass through the through-hole, and the smooth movement of urine from the upper space to the lower space is hindered.

The present invention has been made in view of the above problems, and an object of the present invention is to provide an animal litter box that can prevent the through holes of the partition from being blocked by particulate matter.

The animal toilet according to the present invention includes a main body portion for receiving excreted urine, a partition portion having a through hole through which the urine passes and dividing an internal space of the main body portion into an upper space and a lower space, A roof member is fixed to the partition and covers the through hole from above while being spaced apart from the through hole.

This animal litter box is provided with a roof member that covers the through hole of the partition from above. Therefore, even if the granular material is laid in the upper space, it is difficult for the granular material to reach the through hole because it is blocked by the roof member. Thereby, it is possible to prevent the through hole from being blocked by particulate matter.

According to the present invention, an animal litter box is realized in which the through hole of the partition part is less likely to be blocked by particulate matter.

Embodiments of the present invention will be described in detail below with reference to the drawings. In addition, in the description of the drawings, the same elements are given the same reference numerals and redundant description will be omitted.

FIG. 1 is an end view showing one embodiment of an animal litter box according to the present invention. The outline of the structure of the animal litter box 1 will be explained with reference to the same figure. The animal litter box 1 includes a main body part 10, a partition part 20, a roof member 24, a connecting member 26, a plurality of granules 30, a water absorbent sheet 40, and a drawer part 50. The main body part 10 is made of one container and has a bottom part 10a and a side part 10b. The main body 10 receives excreted urine. The outer shape of the main body portion 10 is approximately a rectangular parallelepiped. As the material of the main body portion 10, for example, plastics such as polypropylene and polyethylene can be used.

The main body portion 10 has a support portion 12 . The support portion 12 projects inside the main body portion 10 from the side surface portion 10b. The support section 12 supports the partition section 20 from below. The support portion 12 is made of, for example, a protrusion or a protrusion. The support portion 12 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.

The partition part 20 is placed on the support part 12. However, the partition section 20 is not fixed to the main body section 10. The partition section 20 is removable from the main body section 10. The partition portion 20 is made of a plate-shaped member. The partition part 20 is arranged parallel to the bottom part 10a. Further, the partition section 20 is arranged at a position spaced apart from both the upper end of the main body section 10 (side surface section 10b) and the water absorbent sheet 40. Thereby, the partition section 20 divides the internal space of the main body section 10 into an upper space S1 and a lower space S2. The upper space S1 exists above the partition part 20, and is a space in which a plurality of granular bodies 30 are laid. The lower space S2 exists below the partition part 20, and is a space in which urine accumulates. The partition portion 20 has a through hole 22 through which urine passes. The through holes 22 allow urine to pass through, but do not allow the particulate matter 30 to pass through. As the material for the partition portion 20, for example, plastics such as polypropylene and polyethylene can be used.

The roof member 24 is fixed to the partition section 20. The roof member 24 is fixed to the partition section 20 via a connecting member 26. The roof member 24 is not fixed to the main body 10. The roof member 24 is made of a horizontal plate-like member. The roof member 24 covers the through hole 22 from above. However, the roof member 24 is spaced upward from the through hole 22. That is, the lower surface of the roof member 24 is located at a higher position than the upper end of the through hole 22 (the upper surface of the partition portion 20). Thereby, a gap exists between the through hole 22 (partition part 20) and the roof member 24. In this way, the roof member 24 covers the through hole 22 from above while being spaced apart from the through hole 22. The above gaps allow urine to pass through, but do not allow the granules 30 to pass through. Urine flows into the through hole 22 through the gap. As the material for the roof member 24 and the connecting member 26, for example, plastics such as polypropylene and polyethylene can be used.

A plurality of granules 30 for treating excrement (mainly urine) are laid in the upper space S1 (above the partition section 20). Each granular body 30 has a granular shape. Examples of such granular shapes include spheres, cylinders, and ellipsoids. The particle size of each granule 30 is, for example, 10 mm or more and 20 mm or less. Here, the particle size of the granules 30 is defined as the diameter of the smallest sphere that can contain the granules 30. When the animal litter box 1 is used, the granules 30 directly receive excreted urine.

The granular material 30 has hydrophobicity. That is, the granular material 30 has the property of not absorbing liquid such as urine at all, or hardly absorbing it at all. In order for the granular material 30 to have hydrophobicity, it is necessary that the liquid passage rate measured by the following test be 60% or more. First, a granular material 30 (sample) equivalent to 50 g is put into a sieve having an inner diameter of 10 cm and an opening of 1 mm. Place an empty beaker under the sieve. Then, 30 ml of water is dropped onto the sample over 10 seconds using a syringe (60 ml syringe manufactured by Terumo Corporation) with an outer cylinder having an inner diameter of 3 cm and a tip having an inner diameter of 4 mm. After leaving it for 1 minute, measure the amount of water in the beaker. The ratio of the measured amount of water to the amount of dropped water (30 ml) is defined as the liquid passage rate. At this time, if the amount of water in the beaker is 18 ml or more, the liquid passage rate is 60% or more, so it can be said that the granular material 30 has hydrophobicity.

It is preferable that each granular body 30 is mainly made of organic matter. Here, the main material of the granules 30 refers to the material that accounts for the largest weight percentage in the granules 30 among the one or more materials that constitute the granules 30. Examples of such organic materials include paper, used tea leaves, plastics, and okara. Each granular body 30 may be made of only organic matter, or may be made of both organic matter and inorganic matter.

Paper refers to materials mainly made of pulp. Examples of the paper include ordinary paper, as well as classified PVC wallpaper, photographic paper, release paper, fluff pulp, papermaking sludge, and pulp sludge. A classified product of PVC wallpaper is obtained by removing a portion of polyvinyl chloride from paper and PVC wallpaper containing polyvinyl chloride. Examples of plastics include, in addition to ordinary plastics, aluminum vapor-deposited films and classified paper diapers (plastics obtained by classifying paper diapers). Preferably, the okara is dried okara. These materials may or may not be subjected to hydrophobic treatment (water repellent treatment).

The number of materials constituting the granular bodies 30 may be one, or two or more. In the former case, the material constituting the granules 30 is only the above-mentioned main material. In the latter case, the granules 30 will be composed of a mixture of the main material and other materials. Other materials include, for example, gypsum or baking soda. By adding gypsum or baking soda, the hydrophobicity of the granules 30 can be increased. The proportion of gypsum or baking soda is, for example, 5% by weight or more and less than 50% by weight based on the entire granular material 30.

The granular material 30 can be manufactured, for example, by the following method. First, a granulated material (material constituting the granular body 30) is granulated using a granulating device to form a granulated material that will become the granular body 30. As the granulator, for example, an extrusion granulator can be used. The granules may be subjected to hydrophobic treatment if necessary. Hydrophobic treatment can be performed, for example, by coating the surface of the granules with a hydrophobic agent (water repellent). When hydrophobic treatment is not performed, it is preferable to increase the pressure applied to the granulated material during granulation to minimize the formation of gaps within the granulated material. This is because such a gap becomes a path for liquid such as urine to infiltrate into the inside of the granular material 30. Prior to granulation, the granulation material is subjected to pretreatments such as crushing, kneading, and adding water as necessary. Further, after granulation, post-treatments such as sieving (granulation) and drying are performed as necessary.

A water absorbent sheet 40 is disposed in the lower space S2 (below the partition section 20). The water absorbent sheet 40 absorbs urine that has passed through the through holes 22 of the partition section 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.

The drawer portion 50 can be inserted into and removed from the main body portion 10 through the opening 14 formed in the side surface portion 10b. The water absorbent sheet 40 is accommodated in the drawer portion 50 . That is, the water absorbent sheet 40 is disposed within the main body 10 while being accommodated in the drawer 50 . As the material for the pull-out portion 50, for example, plastics such as polypropylene and polyethylene can be used.

When the animal litter box 1 is used, urine excreted onto the granules 30 passes through gaps between the granules 30 and flows downward. The urine moves from the upper space S1 to the lower space S2 through the through hole 22 of the partition part 20, and is absorbed by the water absorbent sheet 40.

Hereinafter, the configuration of each part of the animal litter box 1 will be explained in detail with reference to FIGS. 2 to 10. 2 and 3 are an end view and a front view showing the main body 10, respectively. An opening 14 is formed in the side surface 10b of the main body 10 to insert and remove the drawer 50. The opening 14 is located near the bottom portion 10a and has a horizontally long rectangular shape. The length of the opening 14 in the lateral direction (the left-right direction in FIG. 3) is approximately equal to the lateral width (inner dimension) of the main body portion 10, and is, for example, 20 cm or more and 40 cm or less. The length of the opening 14 in the vertical direction (vertical direction in FIG. 3) is, for example, 2 cm or more and 5 cm or less.

FIG. 4 is a plan view showing the main body portion 10. As shown in FIG. The support portion 12 is provided over the entire inner periphery of the side surface portion 10b in plan view. That is, the support portion 12 is composed of a protrusion provided in an annular shape along the inner periphery of the side surface portion 10b. The inner periphery of the side surface portion 10b is approximately rectangular in plan view. Here, the term "substantially rectangular" is intended to include not only rectangles but also shapes close to rectangles such as rounded quadrilaterals. The protruding length of the support portion 12 (the length in the direction perpendicular to the inner surface of the side surface portion 10b on which the support portion 12 is provided) is, for example, 5 mm or more and 15 mm or less.

FIG. 5 is a plan view showing the partition section 20. As shown in FIG. This figure shows the partition portion 20 without the roof member 24 attached. The partition portion 20 can be disposed within the main body portion 10 with its entire periphery spaced apart from the side surface portion 10b. The partition portion 20 has a substantially rectangular shape in plan view. The partition part 20 has a plurality of through holes 22. In the following description, "a plurality of through holes 22" refers to all the through holes 22 provided in the partition portion 20 unless otherwise specified. The plurality of through holes 22 are two-dimensionally arranged in the partition part 20. The planar shape of each through hole 22 is circular. The diameter of each through hole 22 is, for example, 5 mm or more and 10 mm or less.

FIG. 6 is a plan view showing the partition section 20 and the roof member 24. FIG. 7 is an end view taken along line VII-VII in FIG. 6. Moreover, FIGS. 8 and 9 are enlarged views showing a part (a set of through holes 22 and the roof member 24) of FIGS. 6 and 7, respectively. The animal toilet 1 is provided with a plurality of roof members 24. The plurality of roof members 24 cover each through hole 22 individually. The number of roof members 24 is equal to the number of through holes 22. That is, one roof member 24 is provided for one through hole 22. The planar shape of each roof member 24 is circular. In plan view, the area of the roof member 24 is preferably 100% or more and 150% or less of the area of the through hole 22. The area of the through hole 22 is defined as the opening area at the upper end of the through hole 22. In this embodiment, the area of the roof member 24 is larger than the area of the through hole 22. Therefore, the planar shape of the roof member 24 and the planar shape of the through hole 22 are similar to each other. The roof member 24 covers the entire through hole 22 in plan view. That is, the roof member 24 overlaps the entire through hole 22 in plan view. In plan view, the center of the roof member 24 coincides with the center of the through hole 22.

The distance d1 (see FIG. 9) between the roof member 24 and the through hole 22 in the vertical direction of the main body portion 10 (the vertical direction in FIGS. 7 and 9) is preferably equal to or less than the diameter d2 of the through hole 22. The interval d1 is equal to the distance from the lower surface of the roof member 24 to the plane including the upper surface of the partition portion 20. The diameter d2 is defined as the diameter of the opening at the upper end of the through hole 22. The distance d1 is preferably 25% or more of the diameter d2, more preferably 50% or more.

The connecting member 26 connects the partition portion 20 and the roof member 24. The connecting member 26 has a rod shape. The connecting member 26 has one end connected to the partition section 20 and the other end connected to the roof member 24. Specifically, the lower end of the connecting member 26 is connected to the upper surface of the partition section 20, and the upper end of the connecting member 26 is connected to the lower surface of the roof member 24. Thereby, the connecting member 26 extends from the partition portion 20 to the roof member 24. The extending direction of the connecting member 26 is equal to the vertical direction of the main body portion 10. The diameter d3 (see FIG. 9) of the connecting member 26 is preferably 30% or less of the diameter d2 of the through hole 22. As can be seen from FIG. 8, a plurality of (specifically four) connecting members 26 are provided for one roof member 24. The plurality of connecting members 26 are arranged at equal intervals along the periphery of the through hole 22.

The connecting member 26 is provided within the shielding region R1 (see FIG. 8) of the partition portion 20 in plan view. The shielding region R1 is a region of the upper surface of the partition portion 20 that is covered with the roof member 24 in a plan view. In the case of this embodiment, the shielding region R1 is an annular region defined by the periphery of the through hole 22 and the periphery of the roof member 24 in plan view.

FIG. 10 is a perspective view showing the drawer part 50. The drawer portion 50 has a bottom plate 50a, a front plate 50b, a front 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 portion 10a of the main body portion 10. The front plate 50b has substantially the same shape and size as the opening 14. A handle 52 is attached to the front plate 50b.

The effects of the animal toilet 1 will be explained. The animal litter box 1 is provided with a roof member 24 that covers the through hole 22 of the partition section 20 from above. Therefore, even if the granular material 30 is laid in the upper space S1, it is difficult for the granular material 30 to reach the through hole 22 because it is obstructed by the roof member 24. Thereby, the situation where the through hole 22 is blocked by the granular material 30 can be made less likely to occur.

The roof member 24 covers the entire through hole 22 in plan view. This is advantageous in maintaining the entire through-hole 22 in an open state (the through-hole 22 is not blocked with the granular material 30 at all).

The planar shape of the roof member 24 and the planar shape of the through hole 22 are similar to each other. By making the shape of the roof member 24 the same as the shape of the through hole 22 in this way, it becomes easier to keep the width of the shielding region R1 of the partition portion 20 small. The shielding region R1 exists around the through hole 22. Nevertheless, since the shielding region R1 is covered with the roof member 24, urine is unlikely to fall directly onto the shielding region R1. Therefore, reducing the width of the shielding region R1 is advantageous in making it easier for urine to flow into the through hole 22.

In order to reduce the width of the shielding region R1 of the partition portion 20 in this way, it is advantageous for the roof member 24 to have a smaller area. From this point of view, the area of the roof member 24 is preferably 150% or less of the area of the through hole 22 in plan view. On the other hand, if the area of the roof member 24 is too small, the roof member 24 will not be able to cover the entire through hole 22. From this point of view, it is preferable that the area of the roof member 24 is 100% or more of the area of the through hole 22.

When the distance d1 between the roof member 24 and the through hole 22 is equal to or less than the diameter d2 of the through hole 22, it is possible to prevent the granular material 30 from entering the gap between the roof member 24 and the through hole 22. On the other hand, in order to make it easier for urine to flow into the through hole 22 through the gap, it is advantageous to increase the distance d1. From this viewpoint, the distance d1 is preferably 25% or more of the diameter d2, more preferably 50% or more.

The connecting member 26 connects the through hole 22 and the roof member 24. By providing such a connecting member 26, it is possible to easily realize a configuration in which the roof member 24 covers the through hole 22 from above while being spaced apart from the through hole 22.

The connecting member 26 has a rod shape. Naturally, urine cannot pass through the area where the connecting member 26 is present. The presence of coupling member 26 therefore obstructs urine flow. In this regard, by forming the connecting member 26 in an elongated shape (rod shape), the extent to which the flow of urine is obstructed can be suppressed to a small level.

In order to reduce the extent to which the flow of urine is obstructed in this way, it is advantageous for the diameter d3 of the connecting member 26 to be small. From this viewpoint, the diameter d3 is preferably 30% or less of the diameter d2 of the through hole 22. On the other hand, if the diameter d3 is too small, the mechanical strength of the connecting member 26 may be insufficient. From this viewpoint, the diameter d3 is preferably 10% or more of the diameter d2.

The partition part 20 has a plurality of through holes 22. Providing a plurality of through holes 22 in this manner is advantageous in smoothly moving urine from the upper space S1 to the lower space S2.

A plurality of roof members 24 are provided to cover each through hole 22 individually. This makes it possible to prevent any of the through holes 22 from being blocked by the granular material 30.

Each granule 30 has hydrophobicity. In this case, most of the urine excreted onto the granules 30 passes through the gaps between the granules 30 without being absorbed by the granules 30. Thereby, urine can be quickly guided to the through hole 22.

When each granular material 30 is made mainly of organic matter, the granular material 30 suitable for incineration can be obtained. In this case, the used granules 30 can be easily disposed of as combustible waste, improving convenience for users (animal owners, etc.). In particular, when each granule 30 is made of only organic matter, it is possible to obtain granules 30 that are more suitable for incineration.

The main body part 10 consists of one container. In this case, the animal litter box 1 having the upper space S1 and the lower space S2 can be realized with a simpler configuration than when the main body part 10 is composed of a plurality of containers.

The partition section 20 is not fixed to the main body section 10. In this case, the partition section 20 can be easily attached to and detached from the main body section 10.

The partition part 20 is placed on the support part 12. Thereby, the partition part 20 can be kept at a predetermined position within the main body part 10 without being fixed to the main body part 10.

The support portion 12 is provided over the entire inner periphery of the side surface portion 10b in plan view. This makes it easier to prevent the partition portion 20 from falling into the lower space S2.

The partition portion 20 can be disposed within the main body portion 10 with its entire periphery spaced apart from the side surface portion 10b. By providing a margin between the partition portion 20 and the side surface portion 10b in this manner, when the partition portion 20 is attached to and removed from the main body portion 10, the partition portion 20 can be smoothly moved.

A water absorbent sheet 40 is disposed below the partition section 20. Thereby, urine accumulated in the lower space S2 can be confined within the water absorbent sheet 40. Therefore, it is possible to reduce the occurrence of bad odor from the urine.

A drawer portion 50 that can be inserted into and removed from the main body portion 10 is provided. This makes it possible to easily replace the used water absorbent sheet 40 with a new one.

The present invention is not limited to the above embodiments, and various modifications are possible. In the embodiment described above, the case where the planar shape of the roof member 24 and the planar shape of the through hole 22 are similar to each other is illustrated. However, the planar shape of the roof member 24 and the planar shape of the through hole 22 may be congruent with each other. In that case, as shown in FIG. 11, it becomes possible to completely overlap the through hole 22 and the roof member 24 in plan view. By doing so, it is possible to prevent the shielding region R1 from existing in the partition section 20. This is particularly advantageous in facilitating the flow of urine into the through holes 22. At this time, the connecting member 26 is provided so as to extend diagonally, as shown in FIG. 12, for example.

In the above embodiment, the entire upper surface of the roof member 24 is horizontal. However, at least a portion of the upper surface of the roof member 24 may be inclined downward toward the peripheral edge of the roof member 24, as shown in FIGS. 13 and 14, for example. In both figures, the entire upper surface of the roof member 24 is inclined downward toward the periphery of the roof member 24. In FIG. 13, the top surface of the roof member 24 is flat. The position of the upper surface of the roof member 24 gradually becomes lower from one side (left side in FIG. 13) to the other side (right side in FIG. 13) of the roof member 24. In FIG. 14, the upper surface of the roof member 24 has a curved shape (umbrella shape). The position of the upper surface of the roof member 24 gradually becomes lower from the center of the roof member 24 toward the periphery.

By inclining the upper surface of the roof member 24 in this manner, urine that has reached the upper surface easily flows down from the roof member 24. Therefore, it is possible to prevent urine from accumulating on the upper surface of the roof member 24. When the entire upper surface of the roof member 24 is sloped, urine is particularly difficult to accumulate on the upper surface of the roof member 24. When the upper surface of the roof member 24 is planar, the roof member 24 with an inclined upper surface can be realized with a relatively simple structure. When the upper surface of the roof member 24 is curved, urine that has reached the upper surface of the roof member 24 can be uniformly flowed toward the entire periphery of the roof member 24. In addition, when the distance from the lower surface of the roof member 24 to the plane including the upper surface of the partition part 20 is not constant as in this example, the distance d1 between the roof member 24 and the through hole 22 is defined as the maximum value of the above distance. shall be taken as a thing.

In the embodiment described above, the roof member 24 covers the entire through hole 22 in plan view. However, the roof member 24 may cover only a portion of the through hole 22 in plan view.

In the embodiment described above, the planar shape of the through hole 22 is circular. However, the planar shape of the through hole 22 is arbitrary, and may be, for example, an ellipse or a polygon such as a rectangle. In this way, when the planar shape of the through hole 22 is not circular, the diameter d2 of the through hole 22 is defined as the diameter of the smallest circle that can include the opening at the upper end of the through hole 22.

In the embodiment described above, the case where the planar shape of the roof member 24 is circular is illustrated. However, the planar shape of the roof member 24 is arbitrary, and may be, for example, an ellipse or a polygon such as a rectangle. Note that the planar shape of the roof member 24 may be different from the planar shape of the through hole 22.

In the above embodiment, the case where the drawer part 50 is provided is illustrated. However, providing the drawer portion 50 is not essential. When the drawer section 50 is not provided, the water absorbent sheet 40 is placed directly on the bottom surface section 10a. In that case, naturally, the opening 14 is not provided in the side surface portion 10b.

In the above embodiment, the case where the water-absorbing sheet 40 is disposed on the main body 10 has been exemplified. However, it is not essential to provide the water absorbent sheet 40 on the main body portion 10. When the water absorbent sheet 40 is not provided, the drawer portion 50 is also not provided.

In the embodiment described above, the case where the main body part 10 is constituted by one container has been exemplified. However, the main body 10 may be composed of a plurality of containers, as shown in FIG. 15, for example. In the figure, the main body 10 is composed of two containers (containers 62 and 64). Each container 62, 64 has a box shape with a bottom and side surfaces. Containers 62 are stacked on top of containers 64. The bottom portion of the container 62 has a through hole 22 and forms a partition portion 20 . Thereby, the internal space of the container 62 and the internal space of the container 64 become an upper space S1 and a lower space S2, respectively. The side surface of the container 62 and the bottom and side surfaces of the container 64 constitute the main body 10.
