Description

  The present invention relates to a pet toilet sheet used for processing the excrement of pets of small animals such as dogs, cats or rabbits. The present invention also relates to a pet tray for installing a pet toilet seat.

  An increasing number of owners keep pets such as dogs, cats or rabbits. Pet toilet sheets are used so that the excrement of these pets can be easily treated during indoor breeding and walks. The pet toilet sheet of Patent Document 1 has been proposed as a pet toilet sheet that can be easily processed so that the owner's hand does not touch pet excrement when the used pet toilet sheet is disposed of. .

JP 2013-111048 A

  However, the pet toilet sheet proposed in Patent Document 1 only takes into account processing after taking it back to the owner's home. The owner who brought the sheet that has taken in the dung home to home must flush the dung into the toilet and take out the sheet contaminated with the dung as combustible garbage. At that time, the owner's hand gets dirty. Moreover, the owner has installed the pet toilet sheet indoors with respect to the pet raised indoors. Toilet sheets for pets from which feces have been excreted are also poured into the toilet, and sheets that are soiled with feces are put out as combustible waste. Even at that time, the owner's hand gets dirty. If the excrement is only urine, the owner puts out a sheet moistened with urine as combustible waste.

  A pet toilet sheet that is soiled with feces or moistened with urine is placed in the room as combustible garbage, and the smell drifts in the room. Therefore, if a pet toilet sheet soiled with feces or wet with urine can be flushed with a flush toilet as it is, troublesome work is reduced and the owner's hand is not soiled.

Therefore, we propose a toilet sheet for pets that can be flushed in a flush toilet.
A pet toilet sheet according to a first aspect includes a water-absorbing paper layer made of water-soluble water-absorbing paper stacked in a plurality of layers, and a mixed layer of water-absorbing pulverized pulp and water-soluble polymer installed on the water-absorbing paper layer. A staple / rayon cotton layer covering the mixed layer from under the water-absorbing paper layer; a water-soluble waterproof film that is installed from the bottom to the side of the staple / rayon cotton layer and has water-solubility and temporary water resistance;
A water-soluble cover sheet that covers the entirety so as to accommodate a water-absorbing paper layer, a mixed layer, a staple / rayon cotton layer, and a water-soluble waterproof film. And water-insoluble materials are not used for pet toilet seats.

The pet toilet sheet according to the second aspect has an outer periphery when seen in a plan view, and a pet toilet that extends from the first notch and a first notch cut into the outer periphery of the water-soluble covering sheet. A perforation is formed to facilitate cutting the sheet.
In the pet toilet sheet according to the third aspect, the water-soluble cover sheet is composed of an upper cover sheet and a lower cover sheet, and the sides of the upper cover sheet and the lower cover sheet are bonded with an adhesive. The perforations are formed on the upper cover sheet and the lower cover sheet, and the perforations are shifted when viewed in plan.

The pet toilet sheet according to the fourth aspect includes an attracting substance that attracts the pet, and the water-soluble covering sheet covers the attracting substance.
A pet tray on which the pet toilet seat according to the first to fourth aspects is installed,
A liquid leakage detection sensor for detecting liquid leaking from the lower surface of the pet toilet seat is provided.

  After the pet excretes feces or urine into the pet toilet sheet, the owner can transport the pet toilet sheet to the flush toilet and flush the pet toilet sheet and excrement into the flush toilet at the same time. For this reason, the owner can process the pet's excrement easily and hygienically.

FIG. 2 is a perspective view of a pet toilet sheet 10 for pets installed on a pet tray 20. 2 is a perspective view of a pet tray 20. FIG. 1 is a plan view of a pet toilet sheet 10. FIG. It is AA sectional drawing of the toilet seat 10 for pets drawn by FIG.

  Hereinafter, the present embodiment will be described with reference to the drawings. FIG. 1 is a perspective view in which a pet toilet sheet 10 for a pet according to this embodiment is installed on a pet tray 20.

  The pet toilet sheet 10 is, for example, a 40 cm × 55 cm rectangular water-soluble sheet, and the pet tray 20 is a 45 cm × 60 cm rectangular plastic tray. The pet tray 20 uses the lock bar 22 to detachably fix the pet toilet sheet 10.

  The size or shape of the pet toilet sheet 10 and the pet tray 20 can be changed as appropriate. The pet toilet sheet 10 is desirably at least 20 cm × 20 cm in size so that feces can be transported in a state of being placed thereon. Moreover, according to the magnitude | size of a pet, you may make the magnitude | size of the toilet sheet 10 for pets into 30 cm x 45 cm. The pet toilet seat 10 may have a polygonal shape such as a square, a circle, an ellipse, or a triangle.

  When the pet excretes feces on the pet toilet sheet 10, the owner removes the lock bar 22 and peels the pet toilet sheet 10 from the pet tray 20. Then, the owner can carry the pet toilet sheet 10 to the flush toilet with the feces on it and let it flow to the flush toilet as it is. When the pet urinates on the pet toilet sheet 10, the owner removes the lock bar 22, peels the pet toilet sheet 10 from the pet tray 20, and transports the pet toilet sheet 10 wet with urine to the flush toilet Then, it can be poured directly into the flush toilet.

  The pet toilet sheet 10 is water-soluble, but absorbs dung water or urine and does not leak urine to the surface of the pet tray 20 within a certain period of time as described later. Therefore, since the owner basically does not get wet with the liquid such as urine, the surface of the pet tray 20 does not need to clean the surface of the pet tray 20 every time the pet excretes excrement. The owner flushes the used pet toilet sheet 10 into the flush toilet, and then fixes the new pet toilet sheet 10 with the lock bar 22 again.

  The pet toilet sheet 10 according to this embodiment can treat solid excrement such as feces and liquid excrement such as urine together with the pet toilet sheet 10 in a flush toilet, so that excrement can be treated hygienically. Also, the owner does not get his hands dirty. Furthermore, since it is not necessary to place a toilet seat in the room as combustible waste as in the prior art, the smell of feces or urine does not drift in the room.

  In the present embodiment, an example in which the pet toilet sheet 10 for pets is installed on the pet tray 20 indoors is shown. However, the owner can bring only the pet toilet sheet 10 and use the pet toilet sheet 10 for excrement disposal when going out outdoors on a pet walk. For example, the owner can use the pet toilet sheet 10 as it is on the dry ground. In the case of a walk, the pet tray 20 is unnecessary.

  FIG. 2 is a perspective view of the pet tray 20. The pet tray 20 is made of a plastic material such as polypropylene or ABS resin.

  The pet toilet sheet 10 does not use a water-soluble and insoluble leak-proof sheet. For this reason, especially when the urine of the pet is large and the urine is left unattended for a long time, liquid such as urine may leak from the lower surface of the pet toilet sheet 10 and the surface of the pet tray 20 may get wet. If it is left as it is, the pet toilet sheet 10 starts to melt, and if the pet toilet sheet 10 is to be transported, the pet toilet sheet 10 may be torn. A liquid leakage detection sensor 24 is installed on the central surface of the pet tray 20 so as not to leave it wet.

  The liquid leakage detection sensor 24 detects the liquid leakage by conducting between the two wirings by the leaked liquid composed of the two wirings, or detects the liquid leakage by the change in the resistance value. In the present embodiment, the leak detection sensor 24 is composed of two wires and is installed at one place on the central surface of the pet tray 20, but may be arranged at a place other than the central surface. Further, a plurality of leak detection sensors 24 may be arranged at various locations on the surface of the pet tray 20. In the present embodiment, an inexpensive leak detection sensor is used, but a leak detection sensor using a highly accurate laser may be used. When leakage is detected, the signal is sent to the electronic buzzer 26 installed in or near the pet tray 20. In FIG. 2, an electronic buzzer 26 is installed in the frame portion of the pet tray 20. The emitted sound of the electronic buzzer 26 may be not only a buzzer sound but also a melody sound. The electronic buzzer 26 notifies the owner of the liquid leakage by a signal from the liquid leakage detection sensor 24. The owner can transport the pet toilet sheet 10 to the flush toilet before the pet toilet sheet 10 is easily broken, and allow the pet toilet sheet 10 to flow in the flush toilet. Further, instead of the sound of the electronic buzzer 26 or the like, the LED may be turned on to notify the owner of the liquid leakage by light.

(Pet toilet seat structure)
FIG. 3 is a plan view of the pet toilet seat 10. FIG. 4 is a cross-sectional view of the pet toilet sheet 10. In FIG. 4, the pet toilet sheet 10 is exaggerated in the thickness direction, but is actually a thin sheet having a substantially uniform thickness.

  The pet toilet sheet 10 is removed from the pet tray 20 after excrement such as feces or urine is attached. Then, the pet toilet sheet 10 is discarded in the flush toilet together with the excrement. As will be described later, the pet toilet sheet 10 is entirely made of a water-soluble material, and no water-insoluble material is used.

  The planar shape of the pet toilet seat 10 shown in FIG. 3 is a rectangular shape having a pair of sides 15 and a pair of sides 16. The sides 15 and 16 are portions where upper and lower cover sheets 109 (see FIG. 4), which will be described later, are bonded together with an adhesive, and are the outer periphery of the pet toilet sheet 10.

  Two cut portions 11 are formed on one side 15 (+ Y axis direction side) of the pet toilet sheet, and two cut portions 11 are also formed on the other side 15 (−Y axis direction side). A perforation 13 is formed from one cut portion 11 to the other cut portion 11. Similarly, two cut portions 12 are formed on each of the pair of sides (Z-axis direction side) of the pet toilet seat. A perforation 14 is formed from one cut portion 12 to the other cut portion 12. In addition, the cut part 11, the cut part 12, the perforation 13, and the perforation 14 should just be formed in the cover sheet 109 mentioned later.

  The cut portion 11, the cut portion 12, the perforation 13, and the perforation 14 are for allowing the pet toilet sheet 10 to be finely divided after the pet toilet sheet 10 is used. The pet toilet sheet 10 is made of a water-soluble material. When the excrement is urine, it is divided into 9 parts using the cut portions 11 and 12 and the perforations 13 and 14. Thereby, the divided toilet sheet 10 for pets becomes a size of 10-15 cm × 10-15 cm. For this reason, the toilet sheet 10 for pets can be flowed in an appropriate amount without clogging the flush toilet. When the excrement is feces, the feces are put into a flush toilet, and then divided into 9 parts using the cut portions 11 and 12 and the perforations 13 and 14. Thereby, the toilet sheet 10 for pets and feces can be flushed with a flush toilet. Because it can be subdivided finely, it uses a flush toilet, so the user can feel safe both physically and psychologically.

In FIG. 3, the cut portion 11 is provided at two locations on the top and bottom, and the cut portion 12 is provided at two locations on the left and right sides, so that the pet toilet seat 10 can be divided into nine divisions. However, only one of the cut portion 11 or the cut portion 12 may be provided so that it can be divided into three, or the number of the cut portions 11 or the cut portions 12 is increased to divide the pet toilet sheet 10 into 16 pieces and 25 pieces. It may be possible to do so. Moreover, even if the shape of the pet toilet sheet 10 is a circle or an ellipse, if the divided sheet has an area of 100 to 300 cm ² , the flush toilet can be used even if the divided sheet is flushed in the flush toilet. There will be no clogging.

  4 is a cross-sectional view taken along the line AA of the pet toilet seat 10 depicted in FIG. The pet toilet sheet 10 is made of a plurality of water-soluble materials, and has a structure in which a plurality of materials are stacked in layers. The pet toilet sheet 10 is functionally front and back, the + X axis side is the front surface, and the -X axis side is the back surface.

  First, the pet toilet sheet 10 has a water absorbent paper layer 101 that is superposed on four to eight layers. First, the water-absorbing paper layer 101 is processed to be uneven (embossed) so as to form a groove in the Y-axis direction. Excrement such as urine that has penetrated to the water-absorbing paper layer 101 spreads in the Y-axis direction and supplies water due to capillary action.

  On the water absorbent paper layer 101 (+ X axis direction), a mixed layer 103 of pulverized pulp and water absorbent polymer is installed. Specific examples of the pulverized pulp include cellulosic pulp such as plant starch. Naturally produced cellulosic pulp such as recycled materials, paper, wood, stems, organic fibers, cocomos, peat moss, jute, plant hulls, alfalfa, bark, sawdust, fruit peel, chips, strands, pulp, corn and wheat There is. Examples of water-absorbing polymers include polyacrylic acid-based water-soluble polymers.

  The water absorbent paper layer 101 and the mixed layer 103 are wound so as to be entirely covered with the staple / rayon cotton layer 105. That is, under the water absorbent paper layer 101 (−X axis direction) and the mixed layer 103 (+ X axis direction), these lateral directions (± Y axis direction) are covered with the staple / rayon cotton layer 105. The staple / rayon cotton layer 105 is provided so that the water-absorbent paper layer 101 and the mixed layer 103 do not laterally deviate (in the X, Y, and Z-axis directions) in addition to water absorption. Here, the staple rayon cotton means rayon cotton having a short fiber length as compared with a rayon cotton bed described later. Staple / rayon cotton is excellent in water absorption and water-soluble.

  Under the staple / rayon cotton layer 105 (−X-axis direction), a waterproof film 107 extending on the YZ plane is installed. This is to prevent the pet toilet sheet 10 from leaking immediately when there is a large amount of excrement such as urine. Since the waterproof film 107 is water-soluble, the waterproof function of the waterproof film 107 is temporary. Specifically, the waterproof film 107 is a polyvinyl alcohol (PVA) film that is very hydrophilic and soluble in hot water. The duration of waterproofing of the waterproof film 107 depends on the thickness of the film and the amount of urine, but if it is about 15 to 90 minutes, when both sides of the pet toilet sheet 10 are lifted by hand, a part is broken.

  A cover sheet 109 covers the water absorbent paper layer 101, the mixed layer 103, the staple / rayon cotton layer 105, and the waterproof film 107 from above and below. The covering sheet 109 is a wet nonwoven fabric that forms a three-dimensional gather. The material of the covering sheet 109 is a rayon cotton bed and is water-soluble. The sides 15 of the upper and lower cover sheets 109 are bonded with water-soluble, for example, carboxymethylcellulose, polyvinyl alcohol, sodium alginate, or starch adhesive. Similarly, the side 16 shown in FIG. 3 is bonded with a water-soluble adhesive. Cut portions 11 and 12 are formed in the sides 15 and 16 of the cover sheet 109, respectively. In order to prevent the water-absorbing paper layer 101, the mixed layer 103, the staple / rayon cotton layer 105, and the waterproof film 107 from coming out, the notches 11 and 12 are not formed beyond the sides 15 and 16 bonded with the adhesive.

  Since the pet toilet sheet 10 has a functional front and back as described above, when the owner installs the pet toilet sheet 10 on the pet tray 20, the front and back surfaces are distinguished so as not to make a mistake. It is preferable to be able to do this. For example, a note on the back (-X axis direction) may be written as “Please place this side on the tray” or a gorgeous picture may be drawn on the front (+ X axis direction). preferable. The fibers of the water absorbent paper layer 101, the mixed layer 103, the staple / rayon cotton layer 105, and the covering sheet 109 have a fiber length (average fiber length) of 20 mm or less so that the fibers can be easily dispersed with water. Preferably there is. Moreover, since the fiber length is short, the owner can divide the pet toilet sheet 10 into a plurality of pieces by the perforation 13 and the perforation 14 of the upper and lower cover sheets 109.

  As illustrated in FIG. 4, the perforation 14 of the upper cover sheet 109 and the perforation 14 of the lower cover sheet 109 may be shifted by ΔY when viewed in plan from the X-axis direction. Although not shown, similarly, the perforation 13 of the upper cover sheet 109 and the perforation 13 of the lower cover sheet 109 may be shifted by ΔZ when viewed in plan from the X-axis direction. In particular, when the perforation hole is large, if the upper and lower perforations 13 and 14 are overlapped from the X-axis direction, the pet urine enters the perforation hole and is formed on the lower surface of the pet toilet seat 10. This is to prevent it from coming out.

(Pet attracting substance to be attached to toilet seat for pet)
In general, owners are not good at training pet toilets, spending a lot of time on toilet training for younger pets, and entrusting pet trainers to train their toilets. In addition, since it is difficult for an elderly pet to use the toilet, it is preferable that the toilet can be used in a relaxed state. In order to store the pet as a place where the pet excretes, or to store it as a place where the pet can relax and excrete , the pet toilet sheet 10 may incorporate a pet attractant.

  Any layer of the pet toilet sheet 10 (water absorbent paper layer 101, mixed layer 103, staple / rayon cotton layer 105 and waterproof film 107) may contain one or more pet attractants. For example, the attractant can be a plant extract or plant-based material, pheromone, or other marker compound in the urine / feces material.

  Examples of marker compounds include phenol, trimethylpyrazine, dimethylsulfone, indole, 3-methyl-2-buten-1-ol, 3-mercapto-3-methyl-1-butanol, α-valerolactam, pyrazine, methylpyrazine, 2,6-dimethylpyrazine, 1-methylhydantoin and phenylacetamide are included. Further, when the pet is a cat, examples of the attractant for the cat include actinidine, nepetalactone, actinidine, and boschniaquin.

  Further, in addition to the pet attractant, a bactericidal substance that kills germs contained in urine or feces may be added. This bactericidal substance is at least one substance selected from, for example, benzalkonium salt, benzethonium chloride, methyl isopropylphenol, and the like. Furthermore, in addition to the pet attracting substance, a substance having a deodorizing effect may be added. The deodorizing substance has a function of decomposing various malodorous components, such as catechin, tannin, flavonoid, polyphenol, or any one or more selected from laurel oil, sage oil, ginger oil, peppermint essential oil, etc. It is a substance.

  Currently, the toilet sheets for pets that are generally used always contain an absorber and a plastic film for preventing leakage. Since plastic is a chemical fiber, it is collected as garbage after use and burned in an incinerator. Moreover, incineration has a great influence on air pollution, and the cost and load of post-processing are large. In addition, since conventional pet toilet sheets cannot be washed away with flush toilets, after excrement such as feces is flushed with flush toilets, pet toilet sheets must be treated as combustible waste.

  On the other hand, the pet toilet sheet 10 of the present embodiment can be disassembled with a flush toilet and does not need to be incinerated, thereby avoiding environmental pollution. Moreover, since the toilet sheet 10 for pets can be flushed with the excrement in the flush toilet, it is possible to reduce the processing time.
