Description

  The present invention relates to a pet toilet.

  Conventionally, as pet toilets for dogs and cats kept indoors, bentonite that hardens when mineral zeolite, river sand, urine, etc. are absorbed into plastic containers, or pulverized pulp is hardened and molded into granules In general, a toilet in which toilet sand made of so-called cat sand, such as cellulose particles, is laid is used. Pets such as dogs and cats excrete urine and feces from toilet sand.

As a toilet for pets using toilet sand, a toilet is known in which a toilet body is divided into an upper layer portion and a lower layer portion by a cocoon child, toilet sand is laid in the upper layer portion, and urine is stored in the lower layer portion.
Specifically, it is a pet toilet comprising a toilet body, and a urine permeable partition layer that partitions the toilet body into an upper layer portion and a lower layer portion, and the lower layer portion includes a tray for receiving urine, A toilet (see Patent Document 1) provided with a spout for pouring out the urine in the tray on the tray, a urination tray having a toilet sand holding substrate having a plurality of small holes as a bottom wall, and the urination A collecting funnel that is disposed below the tray for collecting and collects urine falling through a small hole in the toilet sand holding surface and discharges the collected urine; and below the collecting funnel A toilet (see Patent Document 2) and the like, which is arranged and includes a urine storage container provided with a mouth portion that receives liquid from a drainage pipe of the collection funnel, is known.

JP 2011-4664 A JP 2006-149372 A

However, in the case of the toilet described in Patent Document 1, the upper surface of the tray is only covered with a spider (partition layer), and the inside of the tray is substantially open, so urine stored in the tray. Is always in contact with the air, and there is a problem that the urine odor tends to spread.
In the case of the toilet described in Patent Document 2, since only the mouth of the urine storage container is opened, the smell of urine stored in the urine storage container is unlikely to diverge, but urine is not collected from the collection funnel. Since it moves to the urine storage container along the slope, urine tends to adhere to the liquid collection surface of the liquid collection funnel. In addition, since there is toilet sand in the upper layer, fine particles and fragments of the toilet sand fall on the liquid collection surface, and when mixed with urine, they tend to accumulate on this liquid collection surface, turn into. In that case, the liquid collection surface of the liquid collection funnel is only covered with a kite (toilet sand holding substrate), so it is virtually open and the urine odor adhering to the liquid collection surface is likely to diverge. There's a problem.

  An object of this invention is to provide the toilet for pets which can suppress the spreading | diffusion of an odor by reducing the opportunity for urine to touch space as much as possible.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
In the present invention, “pet” means small animals such as dogs, cats, rabbits, and hamsters.
In the following description, the plan view longitudinal direction of the pet toilet 1 is the left-right direction, the plan view short direction (width direction) is the front-rear direction, and the height direction is the up-down direction.

  As shown in FIGS. 1 to 3, the pet toilet 1 according to the present embodiment includes a container-type toilet body 100 having an opening on the upper surface, and a partition member that partitions the toilet body 100 into an upper layer portion and a lower layer portion. 200.

The toilet body 100 is mainly a storage member 110 which is a box-shaped container having a substantially rectangular shape in plan view having an opening on the upper surface, and a box-shaped container having a substantially rectangular shape in plan view having an opening on the upper surface. And a tray member 120 that can be stored in the container.
The storage member 110 and the tray member 120 are made of, for example, a synthetic resin such as polyethylene (PE), polypropylene (PP), acrylonitrile-butadiene-styrene copolymer (ABS), or a metal such as stainless steel. The material of the storage member 110 and the tray member 120 may be the same or different.

A partition member 200 is attached to the storage member 110 of the toilet body 100, and the interior of the storage member 110 is partitioned vertically by the partition member 200.
In the present embodiment, projections 111 and 111 as stoppers are provided on the inner surface of the side wall of the storage member 110 so that the partition member 200 does not fall down.

An opening 112 is formed below the partition member 200 in one longitudinal side wall of the storage member 110 (the left side wall in this embodiment), and the tray member 120 can be pulled out from the opening 112. Can be taken out.
A grip portion 121 that is gripped when the tray member 120 is pulled out is provided on the outer surface of the side wall (the left side wall in the case of the present embodiment) on the side from which the tray member 120 is pulled out.
The opening 112 may be provided on both side walls in the longitudinal direction of the storage member 110, or may be provided on one side wall in the width direction or both side walls in the width direction of the storage member 110. Further, the position and the number of the gripping parts 121 can be arbitrarily changed as appropriate according to the position and the number of the openings 112, and the shape of the gripping part 121 can also be arbitrarily changed as appropriate.

In the present embodiment, a liquid return portion 122 that extends toward the inner side in a plan view of the tray member 120 is provided at the upper peripheral edge of the tray member 120.
Thereby, it is possible to suppress the urine N stored in the tray member 120 from spilling due to the rolling of the tray member 120 or the like.

The partition member 200 is a substantially rectangular plate-like member that is detachably attached above the tray member 120 and divides the storage member 110 in the vertical direction. The partition member 200 is made of, for example, a synthetic resin such as polyethylene (PE), polypropylene (PP), or acrylonitrile-butadiene-styrene copolymer (ABS), or a metal such as stainless steel.
In view of strength, weight, ease of molding, etc., it is preferable to use a synthetic resin. Moreover, it is more preferable that the partition member 200 is subjected to water repellent processing.
Moreover, the partition member 200 may be formed integrally with the toilet body 100 (for example, the storage member 110).

The partition member 200 has a large number of through holes 201,... Penetrating in the vertical direction (thickness direction). That is, the through holes 201 are arranged at predetermined intervals in the longitudinal direction and the width direction of the partition member 200 in a plan view. The through holes 201,... Function as liquid passage holes for allowing liquid such as urine N excreted by the pet on the partition member 200 to pass therethrough.
The size of the through holes 201 reflects the particle size of toilet sand (not shown) laid on the upper surface of the partition member 200, and can prevent the toilet sand from falling below the partition member 200. Although it is arbitrary if it is a size, it is preferably a size that does not leave a liquid such as urine N due to surface tension, and specifically about 1 to 5 mm.

In the present embodiment, the portion of the partition member 200 in which the plurality of through holes 201 are provided has a size in plan view that is larger than a size in plan view of the opening surrounded by the liquid return portion 122 of the tray member 120. Is set to be smaller. That is, the left-right length L1 (see FIG. 3) of the partition member 200 where the plurality of through-holes 201 are provided is the left-right direction of the opening surrounded by the liquid return portion 122 of the tray member 120. The length in the front-rear direction of the portion of the partition member 200 provided with the plurality of through holes 201,... Is shorter than the length L2 (see FIG. 3) and is surrounded by the liquid return portion 122 of the tray member 120. The opening is set to be shorter than the length in the front-rear direction.
As a result, the liquid such as urine N that has passed through the through holes 201 of the partition member 200 is surely dropped into the tray member 120 without adhering to the tip portion or the upper surface of the liquid return portion 122. Yes.

Next, a method for using the pet toilet 1 according to this embodiment will be described.
First, the pet owner injects the urine sealing liquid M made of a hydrophobic liquid having a specific gravity smaller than that of the urine N into the tray member 120.
Next, the owner attaches the tray member 120 into which the urine sealing liquid M is introduced to the storage member 110. Further, when the partition member 200 is not attached to the storage member 110, the partition member 200 is also attached. Thereby, the toilet 1 for pets is completed.

  In the pet toilet 1 of the present embodiment, the pet excretes on the partition member 200. The urine N excreted by the pet passes through the through holes 201 of the partition member 200 and falls into the tray member 120 and accumulates. At this time, the urine sealing liquid M is introduced into the tray member 120 to form a layer of the urine sealing liquid M. The urine sealing liquid M is a hydrophobic liquid having a specific gravity smaller than that of the urine N. Therefore, the urine N dropped in the tray member 120 passes through the layer of the urine sealing liquid M without being dissolved in the urine sealing liquid M, and accumulates below the layer of the urine sealing liquid M. Go. Therefore, for example, as shown in FIG. 4, the urine N stored in the tray member 120 is covered and sealed with a layer (sealing layer) of the urine sealing liquid M, that is, the odor is emitted. It is in a suppressed state.

Here, since the specific gravity of urine N such as dogs and cats is generally 1.001 to 1.080, the specific gravity of the urine sealing liquid M is less than 1.001.
The urine sealing liquid M is arbitrary as long as it is a hydrophobic liquid having a specific gravity smaller than that of urine N. For example, various oils such as salad oil, sewing machine oil, silicon oil, bicycle oil, aromatic hydrocarbons and higher grades are used. Alcohol may be used. However, the urine sealing liquid M is preferably one that can be used safely at home. For example, the specific gravity of olive oil is 0.91, the specific gravity of toluene is 0.86, and the specific gravity of butanol is 0.81.

The thickness of the urine sealing liquid M is preferably about 1 to 5 mm. The dimensions of the storage member 110 are such dimensions that cats and small dogs can ride and excrete. For example, the length in the width direction is about 40 cm and the length in the longitudinal direction is about 50 cm. Since the dimensions of the tray member 120 are also the same, about 200 to 1000 cc of urine sealing liquid M may be introduced into the tray member 120 in order to make the thickness of the urine sealing liquid M about 1 to 5 mm.
If the thickness of the urine sealing liquid M is smaller than 1 mm, the urinary sealing liquid M layer is too thin, and a portion that cannot partially cover the urine N is generated, and the odor emission can be effectively suppressed. There is a risk of disappearing. Further, if the thickness of the urine sealing liquid M is larger than 5 mm, the urine sealing liquid M is introduced into the tray member 120 more than necessary, which is not economical.
Further, since the amount of urine N excreted from a cat or small dog for one to two weeks is about 700 to 1400 cc, the depth of the tray member 120 may be about 20 mm, and liquid spillage is effective. In order to suppress it, about 30 mm is preferable.

The urine sealing liquid M is preferably a low-viscosity liquid. Specifically, the viscosity of the urine sealing liquid M is preferably 66 mPa · s or less, more preferably 15 mPa · s or less, and most preferably 7 mPa · s or less.
If the viscosity of the urine sealing liquid M is greater than 66 mPa · s, the urine N that has fallen into the tray member 120 cannot quickly pass through the layer of the urine sealing liquid M. It takes time until the urine N layer is separated and sealed with the urine sealing liquid M layer (sealing layer), that is, the state where the odor emission is suppressed. For example, the viscosity of sewing oil is 7 mPa · s, and the viscosity of compressor oil is 66 mPa · s.

Moreover, the urine sealing liquid M is preferably a liquid having a high flash point, and more preferably a liquid having no flammability. Specifically, the flash point of the urine sealing liquid M is preferably 70 ° C. or higher.
If the flash point of the urine sealing liquid M is lower than 70 ° C., special considerations such as having to be careful of fire are necessary, and handling becomes difficult. For example, the flash point of olive oil is 225 ° C, the flash point of machine oil is 120-270 ° C, and the flash point of toluene is 4 ° C.

Moreover, it is preferable that at least one of a fragrance, a deodorant, and an antibacterial agent is added to the urine sealing liquid M.
When a fragrance is added to the urine sealing liquid M, a fragrance can be emitted from the pet toilet 1. Moreover, when there exists a smell peculiar to the urine sealing liquid M itself, the smell can be masked by adding a fragrance | flavor.
When a deodorant is added to the urine sealing liquid M, the odor of the urine N is removed while passing through the urine sealing liquid M layer or while being sealed with the urine sealing liquid M layer. Therefore, the odor emission can be effectively suppressed and the urine N in the tray member 120 can be discarded with a low odor. Moreover, when there exists a smell peculiar to the urine sealing liquid M itself, the smell can be removed by adding a deodorant.
When an antibacterial agent is added to the urine sealing liquid M, the number of bacteria in the urine N decreases while passing through the urine sealing liquid M layer or while being sealed with the urine sealing liquid M layer. As a result, the odor emission can be effectively suppressed and the urine N in the tray member 120 can be sanitized.

Further, the urine sealing liquid M is preferably colored in a color different from that of the urine N.
When the urine sealing liquid M is colored, the urine N stored in the tray member 120 can also be concealed visually. Further, since the boundary between the urine N layer and the urine sealing liquid M layer is easily understood, it is easy to discard the urine N in the tray member 120 and do not want to discard the urine sealing liquid M. Can be achieved.

Further, the toilet body 100 (at least the tray member 120) is made of a material that can transmit light (that is, transparent or translucent so that the urine N stored in the tray member 120 can be visually recognized from the outside of the tray member 120. It is preferable to form a viewing window made of a material that can transmit light on the toilet body 100 (at least the tray member 120). Thereby, the amount of the urine sealing liquid M and urine N in the tray member 120 can be grasped from the outside of the tray member 120.
In this case, when the urine sealing liquid M is colored in a color different from that of the urine N, it becomes possible to accurately grasp the amount of the urine sealing liquid M and the urine N in the tray member 120.
Further, when a scale indicating the amount of liquid in the tray member 120 is provided in the toilet body 100 (the tray member 120 and / or the storage member 110), the amount of the urine sealing liquid M and urine N in the tray member 120 is accurately determined. It becomes possible to grasp.

When the urine N in the tray member 120 is discarded, the tray member 120 may be pulled out from the storage member 110 and the urine N may be discarded together with the urine sealing liquid M, or only the urine N may be discarded. The urine sealing liquid M may be left in the tray member 120. At this time, the tray member 120 may be tilted and discarded from the opening surrounded by the liquid return portion 122, or the outlet 123 (see FIGS. 11 and 12) may be provided on the side wall or bottom wall of the tray member 120. You may discard from the discharge port 123. FIG.
When discarding the urine N together with the urine sealing liquid M, it is preferable to add a surfactant before the disposal to mix the urine N and the urine sealing liquid M.
Further, when only the urine N is discarded, it becomes possible to solidify and discard only the urine N by sprinkling a super absorbent polymer (SAP) in the tray member 120.

Further, for example, as shown in FIG. 5, if the absorbent article A is laid on the bottom surface of the tray member 120, the urine N and the urine sealing liquid M in the tray member 120 are mainly absorbed. Can be discarded.
The absorbent article A plays a role of absorbing water-like components such as urine N. The timing at which the absorbent article A is laid in the tray member 120 is arbitrary. For example, the absorbent article A may be laid in the tray member 120 before use of the pet toilet 1, or the urine N is discarded. At this time, the absorbent article A may be laid in the tray member 120. Further, when a scale indicating the amount of liquid in the tray member 120 is provided on the toilet body 100, the amount of liquid in the tray member 120 is read from the scale, and the amount of liquid in the tray member 120 is determined. When the fixed amount is reached, the absorbent article A may be laid in the tray member 120.
Here, the absorbent article A includes, for example, an absorbent body A1 containing 70% by weight or more of a highly water-absorbent resin (SAP) and a liquid-permeable sheet material A2 that wraps the absorbent body A1. Are preferred.

The absorbent body A1 may be an absorbent body containing only the superabsorbent resin as long as it contains 70% by weight or more of the superabsorbent resin, and in addition to the superabsorbent resin, cotton or pulp Absorbents containing absorbent materials such as rayon and acetate may be used, but such absorbent materials have a large force to draw in liquid, but have a small holding force, so that they do not drip when discarded. From the viewpoint of suppression and the like, an absorber containing only the superabsorbent resin, that is, an absorber of 100% superabsorbent resin is preferable. Examples of the superabsorbent resin include carboxymethylcellulose, polyacrylic acid and salts thereof, acrylate polymer cross-linked product, starch-acrylic acid graft copolymer, starch-acrylonitrile graft copolymer hydrolyzate, polyoxyethylene cross-linked product Products, crosslinked products of carboxymethyl cellulose, polyethylene oxide, polyacrylamide and other partially crosslinked polymers, or a copolymer of isobutylene and maleic acid are preferably used.
The absorbent body A1 is preferably surrounded by a liquid-permeable covering member such as crepe paper, a liquid-permeable nonwoven fabric, or a perforated sheet, in order to maintain the shape.

The sheet material A2 is a liquid-permeable sheet that receives a body fluid containing a water-like component such as urine N and transports it to the absorber A1.
Examples of the liquid-permeable sheet include a net-like sheet material obtained by plain weaving of yarn such as nylon and polyethylene terephthalate, a film sheet material formed with a large number of through holes, a film sheet material such as polyethylene and polypropylene, and liquid permeability. A woven fabric and a non-woven fabric are suitable, and a nonwoven fabric is particularly suitable. Nonwoven fabrics can be made from synthetic fibers such as polyethylene and polypropylene, synthetic fibers such as polyester and polyamide, recycled fibers such as rayon and cupra, and natural fibers such as cotton. Spunlace method, spunbond method, thermal bond Processed by an appropriate processing method such as a method, a melt blown method, or a needle punch method can be used. From the viewpoint of preventing spillage of the superabsorbent resin, a nonwoven fabric including a spunbond layer and a meltblown layer is preferable.
Here, the sheet material A2 is preferably hydrophilic. If the sheet material A2 is hydrophilic, only the urine N is absorbed and discarded among the urine N and the urine sealing liquid M in the tray member 120. It becomes possible to do.

  The absorbent article A is manufactured, for example, by disposing an absorbent body A1 between two sheet materials A2 and A2, and appropriately bonding the sheet materials A2 and A2 around the absorbent body A1. It may be produced by wrapping the absorbent body A1 with one sheet material A2 and appropriately bonding the sheet material A2 around the absorbent body A1.

Further, for example, as shown in FIG. 5, the absorbent article A is provided with a handle portion A <b> 3 that can extend at least a tip portion to the outside of the tray member 120 in a state of being laid inside the tray member 120. It is preferable.
By providing the handle A3 on the absorbent article A, the owner can move the absorbent article A while holding the handle A3 instead of directly holding the absorbent article A. Therefore, the owner can lay the absorbent article A in the tray member 120 or pull up the absorbent article A from the tray member 120 without soiling hands or the like.
In this embodiment, the thread-like handle portion A3 is provided on the absorbent article A. However, the shape of the handle portion A3 is not limited to the thread shape, and can be arbitrarily changed as appropriate. There may be.
Moreover, the number and position of handle part A3 provided in the absorbent article A can be arbitrarily changed arbitrarily.

Moreover, as shown in FIG. 6, for example, the absorbent article A may have irregularities formed on the surface (upper surface and lower surface). By forming irregularities on the surface of the absorbent article A, the surface area of the absorbent article A is increased as compared with the case where irregularities are not formed on the surface, and the lower surface of the absorbent article A and the tray member 120 are formed. Since a gap is formed between the urine N and the urine N, the urine N can be efficiently absorbed.
The method of forming irregularities on the surface of the absorbent article A is, for example, a method of forming an irregular shape by wrapping the absorbent body A1 with a sheet material A2 and then performing wave processing or profile processing with a hot embossing roll or the like. There may be a method of wrapping the absorbent body A1 with a sheet material A2 having a concavo-convex shape formed by applying a wave processing or profile processing with a hot embossing roll or the like, or other methods. May be.

  Moreover, in the absorbent article A, the absorber A1 may be partitioned. If the absorbent body A1 is not partitioned, the absorbent body A1 is offset when the absorbent article A is laid in the tray member 120, etc., the expansion of the absorbent body A1 is limited, and the absorbent capacity is reduced. There is a case. On the other hand, since the offset of the absorber A1 can be suppressed by partitioning the absorber A1, the urine N can be efficiently absorbed without a decrease in the absorption power.

As a method of partitioning the absorbent body A1, for example, as shown in FIGS. 7 and 8, the absorbent body A1 is formed into a cellular shape by an adhesive portion A4 in which the upper surface side and the lower surface side of the sheet material A2 are directly bonded by heat sealing or the like. It may be a method of dividing into two or other methods. When the absorbent body A1 is partitioned in a cell shape by the adhesive part A4, irregularities are formed on the surface of the absorbent article A, so that the urine N can be absorbed more efficiently.
7 and 8, two adhesive portions A4 extending in the longitudinal direction of the absorbent article A and two adhesive portions A4 extending in the width direction are provided, and the absorbent body A1 is 3 ( Although it is divided into (vertical) × 3 (horizontal), it is not limited to this, and the number of adhesive portions A4 extending in the longitudinal direction and the number of adhesive portions A4 extending in the width direction can be arbitrarily arbitrarily changed. In addition, it is also possible to partition the absorbent body A1 only with the adhesive portion A4 extending in the longitudinal direction or only with the adhesive portion A4 extending in the width direction. Moreover, it is also possible to partition absorber A1 by the adhesion part A4 extended diagonally with respect to the longitudinal direction or the width direction of the absorbent article A. However, it is desirable that the cell volume is a volume that does not cause a decrease in the absorption capacity of the absorber A1 and that the absorber A1 can sufficiently expand, that is, larger than the expansion capacity of the absorber A1. Moreover, it is preferable that the space | interval of adhesion part A4 is 150 mm or less from a viewpoint of suppressing the shift | offset | difference of absorber A1.

  Moreover, in order to suppress the deviation | shift of the absorber A1 produced when laying the absorbent article A in the tray member 120 etc., it is also possible to harden the absorber A1 with a water-soluble adhesive. In this case, the absorbent body A1 may be hardened to such an extent that the adhesive force of the water-soluble adhesive is loosened by contacting the urine N and the absorbent body A1 can be sufficiently expanded.

  Hereinafter, the present invention will be described with reference to specific examples, but the present invention is not limited thereto.

<Example 1>
As a hydrophobic liquid having a specific gravity smaller than that of urine N, sewing oil (manufactured by Kurisu Chemical Industry, viscosity 7 mPa · s, hereinafter referred to as “liquid of Example 1-1”), spindle oil (manufactured by Azette, viscosity 15 mPa) S, hereinafter referred to as “liquid of Example 1-2”), turbine oil (manufactured by Azette, viscosity 34 mPa · s, hereinafter referred to as “liquid of Example 1-3”), compressor oil (manufactured by Azette, viscosity 66 mPa) S, hereinafter referred to as “liquid of Example 1-4”), chainsaw oil (manufactured by Azzet, viscosity 116 mPa · s, hereinafter referred to as “liquid of Example 1-5”) was prepared.

Then, 70 mL of blue colored purified water is put into a 100 mL beaker (diameter 50 mm), and the thickness of the sealing layer (liquid layer of Example 1-1) is about 3 mm. 5.9 mL of liquid was dropped.
Next, the mixture was stirred for 1 minute at 400 rpm with a magnetic stirrer (HS-30D manufactured by AS ONE), and then allowed to stand for 1 minute.
Then, after standing, whether or not the boundary between the sealing layer (liquid layer of Example 1-1) and the water layer (purified water layer) is clear, the sealing layer is compared with before stirring. It was confirmed visually whether it was cloudy.
The results are shown in the column of “Agitation test” in Table 1. Here, “◎” means “the boundary is clear and there is almost no turbidity”, “○” means “the boundary is clear but there is turbidity”, and “△” means “the boundary is somewhat unclear and turbid” is there.

Further, 50 mL of blue colored purified water was put into a 100 mL graduated cylinder (diameter 28 mm), and Example 1-1 was gently so that the thickness of the sealing layer (liquid layer of Example 1-1) was about 5 mm. 3 mL of the liquid was dropped.
Subsequently, 20 mL of purified water colored blue was dropped with a syringe from a position 50 mm higher than the liquid level.
Next, after dropping, whether or not the boundary between the sealing layer (liquid layer of Example 1-1) and the water layer (purified water layer) is clear, whether or not there are liquid bubbles in the sealing layer. It was confirmed visually.
The result is shown in the column of “Drip test” in Table 1. Here, “◎” means “the boundary is clear and there are almost no fine liquid bubbles”, “○” means “the boundary is clear, but there are considerable liquid bubbles”, and “△” means “the boundary is slightly unclear and there is no liquid bubble. It's pretty much. "

In addition, the same agitation test and dripping as the liquid of Example 1-1 were also performed for the liquid of Example 1-2, the liquid of Example 1-3, the liquid of Example 1-4, and the liquid of Example 1-5. A test was conducted. The results are also shown in Table 1.

From the results of the agitation test and the drop test, if a hydrophobic liquid having a specific gravity smaller than that of urine N is used as the urine sealing liquid M, a water-like component (purified water in the case of this example) is formed in the urine sealing liquid M layer. ) And can be sealed.
Further, from the results of Table 1, the smaller the viscosity of the urine sealing liquid M, the easier it is to separate the water-like component and the urine sealing liquid M, and if the viscosity of the urine sealing liquid M is 66 mPa · s or less, Mixing of a water-like component (liquid foam composed of a water-like component) into the layer of the urine sealing liquid M is suppressed, and the water-like component and the urine sealing liquid M are substantially separated, so that the water-like component is sealed in the urine. It turned out that it was almost covered with the layer (sealing layer) of the stop liquid M and sealed.
From the above results, it was found that the water-like component such as urine N can be sealed by the layer of the urine sealing liquid M.

<Example 2>
As a hydrophobic liquid having a specific gravity smaller than that of urine N, sewing oil (manufactured by Kurisu Chemical Industry Co., Ltd., viscosity 7 mPa · s) was prepared.
And sewing oil was dripped so that the thickness of the sealing layer (layer of sewing oil) might be set to about 3 mm in the container of length 140mm x width 125mm x height 100mm.
Next, 150 cc of 3% ammonia water was gently injected into the container with a syringe, and the container was left in an open system without covering the container until the ammonia water moved below the sealing layer.
Next, the container was covered and allowed to stand for 1 minute, and then the ammonia concentration was measured with a gas-tech detector tube and sensory evaluation was performed.
The results are shown in Table 2. Here, “1” for sensory evaluation is “scent that can be finally detected”, “2” is “weak scent that can understand what smell”, “3” is “scent that can be easily detected”, and “4” is “ “Strong smell” and “5” are “strong smell”.

<Comparative example>
Moreover, the same density | concentration measurement and sensory evaluation were performed also about the case where sewing machine oil is not included (it does not introduce | transduce). Specifically, 150 cc of 3% ammonia water was poured into a container 140 mm long x 125 mm wide x 100 mm high, allowed to stand for 1 minute, capped, and measured for ammonia concentration with a gas tech detector tube. Evaluation was performed. The results are also shown in Table 2.

  From the results in Table 2, it was found that if a hydrophobic liquid having a specific gravity smaller than that of urine N is used as the urine sealing liquid M, the urine sealing liquid M layer can suppress the emission of odor.

  As described above, according to the pet toilet 1 of the present embodiment, the container-type toilet body 100 having an opening on the upper surface and the plurality of through holes 201 penetrating in the vertical direction are provided. Is used in a state where a hydrophobic liquid (urine sealing liquid M) having a specific gravity smaller than that of urine N is introduced into the lower layer part.

Therefore, in a state where the urine N is sealed with a layer of a hydrophobic liquid (urine sealing liquid M) having a specific gravity smaller than that of the urine N, the lower layer portion of the toilet body 100 (in this embodiment, the tray member 120). ), It is possible to suppress odor emission.
In addition, since there is no collection funnel that guides urine N to the lower layer portion of the toilet body 100 and the urine N falls directly from the upper layer portion of the toilet body 100 to the lower layer portion, the urine N and the toilet are placed in the collection funnel. There is no inconvenience such as sand accumulation and odor emission.
Moreover, since the height of the pet toilet can be suppressed as compared with the case where the liquid collection funnel is provided, the pet toilet can be used even by a dog.

  Further, according to the pet toilet 1 of the present embodiment, the liquid return portion 122 that extends toward the inner side in the plan view of the toilet body 100 is provided below the partition member 200 on the inner surface of the toilet body 100. The part of the partition member 200 provided with the plurality of through holes 201 is smaller in size in plan view than in the plan view of the opening surrounded by the liquid return portion 122.

Thus, by providing the liquid return part 122 in the toilet body 100, urine N and the like stored in the lower layer portion of the toilet body 100 (in the case of the present embodiment, the tray member 120) is less likely to spill.
Further, by restricting the size of the part of the partition member 200 in which the plurality of through holes 201 are provided in plan view, the liquid such as urine N that has passed through the through holes 201 of the partition member 200 is liquid. Since it can suppress adhering to the front-end | tip part and upper surface of the return part 122, urine N adheres to the liquid return part 122, and it becomes difficult to produce inconveniences, such as an odor emitting from there.
In addition, in this embodiment, although the liquid return part 122 was provided in the tray member 120, the liquid return part 122 should just be provided in the toilet main body 100, for example, may be provided in the storage member 110.
The toilet body 100 may not include the liquid return unit 122. When the toilet body 100 does not include the liquid return portion 122, the size of the portion of the partition member 200 in which the plurality of through holes 201 are provided in plan view is the plane of the upper surface opening of the tray member 120. It only needs to be smaller than the visual size.

  Further, according to the pet toilet 1 of the present embodiment, the toilet body 100 includes the tray member 120 that constitutes the lower layer portion, and the storage member 110 that accommodates the tray member 120 so as to be removable.

Therefore, since the urine N and the like are stored in the tray member 120, the urine N and the like are easily discarded, and the toilet body 100 is easily cleaned.
The toilet body 100 may not be configured to be attached / detached by sliding the tray member 120 in the left / right direction (or front / rear direction), but may be configured to be attached / removed by being taken in and out from the upper surface opening of the storage member 110. In the case of this configuration, the opening 112 is not necessary.
The toilet body 100 may not be divided into the storage member 110 and the tray member 120. Further, the toilet body 100 may be separable up and down. In this case, for example, the partition member 200 is attached to the upper part, and the lower part corresponds to the tray member 120.

  As described above, according to the urine sealing liquid M of the present embodiment, the urine storage container (which is a pet toilet 1 in the case of the present embodiment) is made of a hydrophobic liquid having a specific gravity smaller than that of the urine N and stores urine. ) To be used, a sealing layer for sealing the urine N is formed in the upper layer of the urine N.

Therefore, since the urine N accommodated in the urine storage container can be covered and sealed with the layer (sealing layer) of the urine sealing liquid M, it is possible to suppress the odor emission.
The urine storage container for storing urine may be a container for storing pet urine or a container for storing human urine.

  Moreover, according to the urine sealing liquid M of this embodiment, it is preferable that a viscosity is 66 mPa * s or less.

  By setting the viscosity of the urine sealing liquid M to 66 mPa · s or less, the urine N and the urinary sealing liquid M are quickly separated, and it is possible to quickly prevent the odor from being emitted.

  Moreover, according to the urine sealing liquid M of this embodiment, it is preferable that a flash point is 70 degreeC or more.

  By setting the flash point of the urine sealing liquid M to 70 ° C. or higher, it is not necessary to take special considerations such as having to be careful of fire, and it becomes easy to handle.

  Moreover, according to the urine sealing liquid M of this embodiment, it is preferable that at least one of a fragrance, a deodorant, and an antibacterial agent is added.

By adding the fragrance to the urine sealing liquid M, the fragrance can be released from the urine storage container that stores urine. Moreover, when there exists a smell peculiar to the urine sealing liquid M itself, the smell can be masked by adding a fragrance | flavor.
Further, by adding a deodorant to the urine sealing liquid M, the odor of the urine N is removed while passing through the urine sealing liquid M layer or while being sealed with the urine sealing liquid M layer. As a result, it is possible to effectively suppress the emission of odor and to discard the urine N in the urine storage container for storing urine in a state with little odor. Moreover, when there exists a smell peculiar to the urine sealing liquid M itself, the smell can be removed by adding a deodorant.
Further, by adding an antibacterial agent to the urine sealing liquid M, the number of bacteria in the urine N is increased while passing through the urine sealing liquid M layer or while being sealed with the urine sealing liquid M layer. Since it decreases, the emission of odor can be effectively suppressed, and the urine N in the urine storage container for storing urine can be sanitized.

  Moreover, according to the urine sealing liquid M of this embodiment, it is preferable that it is colored in a color different from the urine N.

  By coloring the urine sealing liquid M, it is possible to conceal the appearance of the urine N stored in the urine storage container that stores urine. Further, when the urine N in the urine storage container for storing urine is discarded, the boundary between the urine N layer and the urine sealing liquid M layer can be easily understood, so that it is easy to discard only the urine N. Can be achieved.

  As described above, according to the absorbent article A of the present embodiment, the absorbent body A1 containing 70% by weight or more of the superabsorbent resin, and the liquid-permeable sheet material A2 that wraps the absorbent body A1 are provided. The urine storage container (in the case of this embodiment, the pet toilet 1) used in a state where a hydrophobic liquid (urine sealing liquid M) having a specific gravity smaller than that of the urine N is introduced is used.

Therefore, since the absorbent article A includes the absorbent body A1 containing 70% by weight or more of the superabsorbent resin and does not include the leak-proof layer inside the absorbent body A1, urine movement is inhibited in the middle. Therefore, it becomes possible to efficiently absorb the urine N stored in the urine storage container on both sides.
In particular, when laid in a urine storage container used in a state in which a hydrophobic liquid (urine sealing liquid M) having a specific gravity smaller than that of urine N is introduced, a leak-proof layer is provided inside the absorber, Depending on how the absorbent article is soaked, the upper and lower absorbent layers may not be used effectively. However, in the case of this embodiment, the absorbent body A1 is not provided with a leak-proof layer. Regardless, it is possible to absorb efficiently on both sides.
In addition, since the absorbent body A1 contains 70% by weight or more of a highly water-absorbent resin, the main component of the hydrophobic liquid (urine sealing liquid M) and the urine N having a specific gravity smaller than that of the urine N in the urine storage container. It is possible to absorb urine N.

  Moreover, according to the absorbent article A of this embodiment, it is preferable that the sheet material A2 is hydrophilic.

By making the sheet material A2 hydrophilic, the urine N accommodated in the urine container can be more efficiently absorbed on both sides.
Further, by making the sheet material A2 hydrophilic, it is possible to absorb only urine N out of a hydrophobic liquid (urine sealing liquid M) and urine N having a specific gravity smaller than that of urine N in the urine storage container. It becomes possible.

  Moreover, according to the absorbent article A of this embodiment, it is also possible to form unevenness on the surface.

  By forming irregularities on the surface of the absorbent article A, the surface area of the absorbent article A is increased, and a gap is formed between the lower surface of the absorbent article A and the bottom surface of the urine storage container. Can be absorbed.

  Moreover, according to the absorbent article A of this embodiment, the absorber A1 may be partitioned.

  By dividing the absorbent body A1, the displacement of the absorbent body A1 is suppressed, so that the expansion of the absorbent body A1 is not limited, and the urine N can be efficiently absorbed.

  Further, according to the absorbent article A of the present embodiment, at least the distal end portion can extend to the outside of the urine storage container while being laid in the urine storage container (in the case of the present embodiment, the pet toilet 1). It is preferable to provide a handle A3.

  By providing the handle A3 on the absorbent article A, it is possible to lay the absorbent article A in the urine storage container or pull up the absorbent article A from the urine storage container without making the hands dirty. It becomes.

  As mentioned above, although concretely demonstrated based on embodiment which concerns on this invention, this invention is not limited to the said embodiment, It can change in the range which does not deviate from the summary.

<Modification 1>
For example, as shown in FIGS. 9 and 10, a plurality of liquid guiding portions 202,... Extending downward may be formed on the lower surface of the partition member 200.
Specifically, the liquid introduction part 202 shown in FIGS. 9 and 10 includes a liquid introduction body 202a that protrudes from each intersection of a vertical line part and a horizontal line part that form the through holes 201,. It comprises ribs 202b extending from the side surface toward the other liquid introduction main body 202a adjacent to the liquid introduction main body 202a. The rib 202b protrudes from the vertical line part or the horizontal line part, and is formed in a shape that draws an arch between adjacent ribs 202b.

The length (length in the vertical direction) of the liquid introduction part 202 is preferably long.
In the case of a configuration in which the tray member 120 is slid in the horizontal direction (in the case of this variation, the left-right direction, but may be in the front-rear direction) as in this variation, for example, in FIG. As shown, a length that does not interfere with the attachment / detachment of the tray member 120 is preferable.
However, even if the tray member 120 is slid in the horizontal direction and attached and detached, in the case of the type in which the tray member 120 is attached and detached with the partition member 200 removed, the length of the liquid introduction part 202 is The length with which the front-end | tip touches the bottom face of the toilet main body 100 is preferable.
Further, in the case of a configuration in which the tray member 120 is put in and taken out from the upper surface opening of the storage member 110, the tray member 120 is attached and detached with the partition member 200 removed, so the length of the liquid introduction part 202 is The length that the front end touches the bottom surface of the tray member 120 is preferable.
Further, even when the toilet body 100 is not divided into the storage member 110 and the tray member 120, or when the toilet body 100 is separable in the vertical direction, the length of the liquid introduction part 202 is the bottom of the toilet body 100. The length that touches is preferable.

  By providing a plurality of liquid introduction portions 202,... On the lower surface of the partition member 200, the urine N that has passed through the through holes 201,. Since it will be separated from the partition member 200 at a position close to the member 120), it is possible to suppress the splash of liquid when the urine N falls to the lower layer portion of the toilet body 100. Further, when the urine N splashes, it becomes easy to form fine water droplets, and it becomes difficult to pass through the layer of the urine sealing liquid M. However, by suppressing the liquid splash of the urine N by the liquid introduction part 202. The urine N can smoothly pass through the layer of the urine sealing liquid M, and the odor emission can be effectively suppressed.

Further, by providing the partition member 200 with the liquid guide portion 202 including the liquid guide body 202a and the rib 202b, the urine N that has passed through the through holes 201,... Of the partition member 200 is guided through the rib 202b. Since the liquid body 202a moves to the tip of the liquid body 202a, the urine N that has passed through the through holes 201,... Of the partition member 200 does not stay at the vertical line portion or horizontal line portion that forms the through holes 201,. , Can be smoothly guided into the tray member 120.
Moreover, since the liquid introduction part 202 extends perpendicularly to the lower surface of the partition member 200, urine N and toilet sand are less likely to adhere as compared to a liquid collection funnel having an inclined surface. It is easy to fall down.
Further, by providing the plurality of liquid introduction portions 202,... On the lower surface of the partition member 200, even if a pet rides on the upper surface of the partition member 200, it becomes difficult for the pet to bend downward.
In addition, the shape and position of the liquid introduction unit 202 can be arbitrarily changed as appropriate. In this modification, the tip of the liquid introduction part 202 (liquid introduction main body 202a) is tapered, but the tip of the liquid introduction part 202 may not be tapered.

<Modification 2>
For example, as shown in FIG. 11, the lower part of the side wall of the toilet body 100 (the tray member 120 in the case of this modification), or the toilet body 100 (the tray member in the case of this modification), for example, as shown in FIG. 120) may have a discharge port 123 for discharging urine N. In this case, the pet toilet 1 is used in a state where the discharge port 123 is closed with the plug 123a.
Thus, by providing the discharge port 123 in the lower side wall or bottom wall of the toilet body 100, the operation of discarding only the urine N below the layer of the urine sealing liquid M can be easily performed.

When the discharge port 123 is provided in the lower side wall or the bottom wall of the toilet body 100, the bottom surface of the toilet body 100 (in the case of this modification, the tray member 120) is connected to the discharge port 123, for example, as shown in FIGS. It is preferable to incline downward.
In the case where the bottom surface is horizontal and does not incline downward toward the discharge port 123, even if urine N is discharged from the discharge port 123, the boundary surface between the urine N layer and the urine sealing liquid M layer The area hardly changes and the thickness of the urine sealing liquid M is also almost constant.
On the other hand, when the urine N is discharged from the discharge port 123 by tilting the bottom surface downward toward the discharge port 123, the area of the boundary surface between the urine N layer and the urine sealing liquid M layer is increased. As the layer of the urine sealing liquid M gradually becomes thicker, the boundary between the urine N layer and the layer of the urine sealing liquid M becomes clear, and only the urine N is discarded to seal the urine The stop liquid M can be easily achieved if it is not desired to discard it.
The position and size of the discharge port 123 can be arbitrarily changed as appropriate.

<Modification 3>
For example, as shown in FIG. 13, a recess 124 may be provided on the bottom surface of the toilet body 100 (in the case of this modification, the tray member 120).
For example, the recess 124 is formed to have a length of about 150 mm in the left-right direction and a length of about 100 mm in the front-rear direction, and the absorbent article A having a size that can be accommodated in the recess 124. It is provided for laying in 124 or putting an appropriate amount of superabsorbent resin into the recess 124.

By providing the recess 124 on the bottom surface of the toilet body 100, the urine N layer can be thickened. Therefore, only the urine N below the layer of the urine sealing liquid M can be absorbed by the absorbent article A or the highly water-absorbent resin in the recess 124, and the urine sealing liquid M is absorbed. It is economical because it can be suppressed.
Moreover, when the recessed part 124 is not provided in the bottom face of the toilet body 100, it is usual to lay the absorbent article A of the same size as the bottom face of the toilet body 100, but the recessed part 124 is provided in the bottom face of the toilet body 100. Thus, the size of the absorbent article A can be reduced. Further, since the size of the absorbent article A is small, the contact area between the absorbent article A and the urine sealing liquid M can be reduced, and even if the urine sealing liquid M is absorbed by the absorbent article A, Since the absorption amount is small, the replenishment amount is small. Further, if the size of the absorbent article A is small, the amount of dust can be reduced.

  As shown in FIG. 14, for example, the absorbent article A laid in the recess 124 may have a shape / size that can be accommodated in the recess 124. For example, as shown in FIG. The shape in which the absorbent body A1 of the absorbent article A is disposed in the recess 124 and covers almost the entire bottom surface of the toilet body 100 (the tray member 120 in this modification) with the sheet material A2 of the absorbent article A. It may be a size.

When the recess 124 is provided on the bottom surface of the toilet body 100, the bottom surface of the toilet body 100 (in this modification, the tray member 120) is inclined downward toward the recess 124 as shown in FIG. preferable.
In the case where the bottom surface is horizontal and does not incline downward toward the concave portion 124, even if the urine N is absorbed by the absorbent article A or the highly water absorbent resin in the concave portion 124, the urine N layer and the urine seal Since the area of the boundary surface with the stop liquid M layer hardly changes and the thickness of the urine sealing liquid M layer is substantially constant, the boundary between the urine N layer and the urinary sealing liquid M layer is not uniform. It tends to be clear.
On the other hand, when the urine N is absorbed by the absorbent article A or the highly water-absorbent resin in the recess 124 by inclining the bottom surface toward the recess 124, the urine N layer and the urine sealing liquid Since the area of the boundary surface with the M layer gradually decreases and the urine sealing liquid M layer gradually increases, the boundary between the urine N layer and the urinary sealing liquid M layer becomes clear. This can be easily achieved when only urine N is absorbed and urine sealing liquid M is not desired to be absorbed.
The position and size of the recess 124 can be arbitrarily changed as appropriate.

<Other variations>
For example, in the above-described embodiment and the above-described modification, the shape of the toilet body 100 is described by exemplifying a box-shaped container having a substantially rectangular shape in plan view. However, the shape is not limited thereto, and for example, in plan view May be a square container or a circular container.

  Moreover, in the said embodiment and the said modification, although the mesh-shaped thing is illustrated and demonstrated as an arrangement | sequence of the through-holes 201, ..., it is not limited to this, For example, it arranges in a grid | lattice form. It may be arranged in an irregular shape. Further, the shape of the through holes 201,... Is not limited to any other shape such as a circle, an ellipse, a polygon such as a quadrangle, and any shape can be used.

  In addition, the detailed configuration and detailed operation of the pet toilet and the absorbent article can be appropriately changed without departing from the spirit of the present invention.
