Description

  The present invention relates to a pet urine absorbing tool useful as a urination treatment material for pets, which are pet animals.

  In recent years, an increasing number of pets, pets, are kept indoors. When a pet is raised indoors, a pet urine absorber called a pet sheet is used as a urine treatment material for absorbing and collecting urine excreted by the pet. Such a pet urine absorber is used by being laid horizontally in the excretory container or on the floor.

  The urine absorbing device for pets has a configuration in which an absorption layer is interposed between a top sheet formed of a nonwoven fabric and a back sheet made of synthetic resin. The absorbent layer includes thin paper, fluff pulp, and a polymer absorber. The polymer absorber is a polymer absorber that absorbs moisture and solidifies into a gel. The absorbent layer is formed in a layered form by mixing fluff pulp and a polymer absorber and sandwiching them with thin paper from both sides in the thickness direction.

  The top sheet is a porous member and has liquid permeability. A fine void is formed between each fluff pulp fiber of the absorbent layer. The absorption layer can absorb moisture by capillary action. The back sheet is a synthetic resin sheet and does not have water permeability. Therefore, when urine is discharged to the top sheet of the pet sheet, the urine passes through the top sheet and the thin paper, is absorbed by the fluff pulp region and the polymer absorber of the absorption layer, and the infiltration region in the thickness direction by the back sheet. Expansion is blocked.

  However, when a pet urine absorber is laid on an excretory container and used, if the pet urinates at the corner of the excretory container, part of the urine is scattered on the peripheral wall of the excretory container, and the urine scattered on the peripheral wall Is guided to the bottom of the excretory container through the inner surface of the peripheral wall. In such a case, since the back sheet does not have liquid permeability, there is a problem that urination guided to the bottom remains as it is at the bottom. Also, when the pet urine absorber is laid on the floor and used, if the pet urinates near the periphery of the pet urine absorber, part of the urine leaks from the edge of the pet urine absorber. There is a problem that the urine leaked out and leaked remains on the floor surface. Therefore, it is not sufficient to process the pet sheet when processing pet urination, and there is a problem that it becomes necessary to clean the excretory container, clean the floor, and the like. Further, since urine remains at the bottom of the excretory container, there is a problem that odor is generated with the passage of time, causing discomfort to surrounding humans and pets.

  FIG. 4 is a partial enlarged cross-sectional view showing a typical prior art pet urine absorber 1, and FIG. 5 is a plan view of the typical prior art pet urine absorber 1 shown in FIG. 4. is there.

  The conventional pet urine absorber 1 is configured by interposing an absorbent body 4 between a liquid-permeable first surface sheet 2 and a liquid-impermeable second surface sheet 3. Such a conventional pet urine absorber 1 faces a pet riding on the pet urine absorber 1 in order to urinate the first top sheet 2 in the pet excretion container or on the floor surface. Used as laid. The pet urine absorber 1 used in this way is described in Patent Document 1, for example.

JP 2003-158930 A

  In the prior art described in Patent Document 1 described above, urine excreted on the surface of the excretory container or above the pet urine absorbing device laid on the floor surface is disposed around the excretion region of the first surface sheet. While spreading, it penetrates into the absorbent body just below the excretion region in the thickness direction and the surface direction by capillary action, reaches the second surface sheet on the back surface side, and penetrates while expanding the infiltration region in the surface direction. This infiltrating region proceeds until all of the excreted urine is absorbed by the absorber and no capillary action occurs.

  When a pet urine absorber is laid on an excretory container and used, urine may be scattered on the peripheral wall of the excretory container depending on the position or posture of the pet when excreted. Guided to the bottom through the inner surface. However, the conventional urine absorbing device for pets cannot absorb the urine flowing into the bottom because the second surface sheet is made of a non-liquid-permeable sheet having non-liquid permeability as described above. There is a problem that it remains at the bottom of the excretory container.

  In addition, when a pet urine absorber is laid on the floor and used, a part of the urine leaks from the pet urine absorber depending on the position or posture of the pet's excretion, and the end of the pet urine absorber There is a problem that the urine leaked through the section and guided to the floor surface remains on the floor surface.

  An object of the present invention is to provide a pet urine absorbing device in which excreted urine does not remain on the bottom or floor surface of the excretory container regardless of the position and posture of the pet when excreted.

The present invention includes a first surface sheet having air permeability and liquid permeability;
A second surface sheet having air permeability and liquid permeability;
An absorber composed of fluff-like fibers interposed between the first and second surface sheets;
Partitioning the absorbent body into a first absorption region on the first surface sheet side and a second absorption region on the second surface sheet side, including a non-liquid-permeable sheet having non-liquid permeability,
The absorbent body is a pet urine absorbent, characterized in that it has a continuous region that is continuous with a first absorption region and a second absorption region.

  In the invention, it is preferable that the absorber includes a water-absorbing polymer.

  According to the present invention, since the first surface sheet and the second surface sheet are air permeable and liquid permeable, on the surface facing above the urine absorbing device for pets laid in the excretory container or on the floor surface While the urine excreted in the first surface sheet spreads from the excretion region to the surroundings, the urine excreted in the thickness direction and the surface direction by capillarity to the first absorption region, which is an absorbent body directly below the excretion region, and does not pass through. It reaches the liquid sheet and penetrates while expanding the infiltration area in the surface direction. Moreover, a part of the urine that has reached the non-liquid-permeable sheet penetrates from the first absorption region to the second absorption region while expanding the infiltration region in the thickness direction through the continuous region.

  When a pet urine absorber is laid on an excretion container and used, urination that has scattered on the peripheral wall of the excretion container and has reached the bottom of the excretion container without being absorbed by the first absorption region will occur at the bottom of the excretion container. Then, it penetrates in the thickness direction and the plane direction from the second surface sheet to the second absorption area by capillary action, reaches the non-liquid-permeable sheet, and penetrates while expanding the infiltration area in the plane direction. As described above, even when the urine is scattered on the peripheral wall of the excretory container depending on the position or posture at the time of excretion of the pet and the urine scattered on the peripheral wall is guided to the bottom through the inner surface of the peripheral wall, Therefore, it is possible to prevent urination from remaining at the bottom of the excretion container.

  Moreover, since the absorbent body is partitioned into a first absorption region on the first surface sheet side and a second absorption region on the second surface sheet side and includes a non-liquid-permeable sheet having non-liquid permeability, it was excreted. Even if a part of urine penetrates the first absorption region of the absorber from the first surface sheet side, the expansion of the infiltration region in the thickness direction is once blocked by the non-liquid-permeable sheet. Much of the urination that has penetrated from is absorbed in the first absorption region. Therefore, when the remaining excreted urine is guided to the bottom along the inner peripheral wall surface of the excretory container, the second absorption region has sufficient liquid absorbing power. It can absorb enough from the 2 surface sheet side, and it can prevent that urination remains in the bottom part of an excretion container.

  Moreover, since an absorber has a continuous area | region connected to a 1st absorption area | region and a 2nd absorption area | region, even if it is a case where a pet urinates in the peripheral part of the urine absorber for pets, for example, via a continuous area | region It is possible to prevent urine from penetrating from one region to the other region and urinate from leaking from the end of the pet urine absorber. Therefore, it is possible to prevent leaked urine from reaching the floor or the bottom of the excretory container.

  Further, according to the present invention, since the absorbent body contains a water-absorbing polymer, a large amount of urination can be absorbed and retained.

1 is a cross-sectional view of a pet urine absorber 10 according to an embodiment of the present invention. It is a perspective view of pet urine absorber 10 of this embodiment. It is a figure which shows the state in which the dog 22 which is a pet is urinating in the pet urine absorber 10 of this embodiment. It is a partial expanded sectional view which shows the typical prior art pet urine absorber 1. It is a top view of the typical prior art pet urine absorber 1 shown in FIG.

  FIG. 1 is a cross-sectional view of a pet urine absorber 10 according to an embodiment of the present invention. FIG. 2 is a perspective view of the pet urine absorber 10 of the present embodiment. The pet urine absorbing device 10 may be laid in the excretion container or directly on the floor surface. However, in the following, the pet urine absorbing device 10 is used by being laid in the excretion container 11. Give an explanation. The pet urine absorber 10 of the present embodiment is a sheet-like absorbent article that is used by being laid almost horizontally in the excretion container 11 that is a pet urination place, and pets such as dogs and cats excreted. Used to absorb and collect urine. The excretory container 11 is a non-porous container capable of storing a liquid, and a synthetic resin integrally formed with a peripheral wall 11b that rises substantially perpendicularly from four side edges of a flat rectangular bottom 11a. It is a made container.

  The pet urine absorber 10 includes a first surface sheet 12 having air permeability and liquid permeability, a second surface sheet 13 having air permeability and liquid permeability, an absorber 14 and an absorber 14 on the first surface sheet 12 side. The first absorption region 15 and the second absorption region 16 on the second surface sheet 13 side are partitioned, and a non-liquid-permeable sheet 17 having non-liquid permeability is included.

  In the pet urine absorber 10, the first surface sheet 12 and the second surface sheet 13 have substantially the same size in the surface direction, and are joined at the peripheral edge portion 18 by hot melt bonding or the like. An absorber 14 is interposed between the second topsheet 13 and the second topsheet 13. In addition, a non-liquid-permeable sheet 17 having non-liquid permeability is interposed in the absorbent body 14, and the non-liquid-permeable sheet 17 causes the absorbent body 14 to be connected to the first absorbent region 15 on the first surface sheet 12 side and the first absorbent area 15. It is partitioned into a second absorption region 16 on the two-surface sheet 13 side. The absorber 14 includes a continuous region 23 that is continuous with the first absorption region 15 and the second absorption region 16.

  The 1st surface sheet 12 and the 2nd surface sheet 13 should just be a sheet | seat which has air permeability and liquid permeability, for example, the fiber sheet or fiber web which consists of a synthetic fiber and a reproduction | regeneration fiber is physically entangled with each other A formed nonwoven fabric or the like can be used. In this embodiment, it is formed using a nonwoven fabric. Since the first surface sheet 12 and the second surface sheet 13 are air-permeable and liquid-permeable sheets, they can absorb urine from either the first surface sheet side or the second surface sheet side. it can. Moreover, the inner surface which faces the absorber 14 of the 1st surface sheet 12 and the 2nd surface sheet 13 is contacting the absorber 14 over the whole surface.

  The absorber 14 includes a fluff-like fiber 19, a water absorbent polymer 20, and a deodorant 21. The fluffy fiber 19 is obtained by cutting a pulp into a length of 1 mm or more and 10 mm or less, and a cotton-like pulp can be used. Since the absorbent body 14 is formed of fluff-like fibers 19, the absorbent body 14 has a large number of voids between the fibers. Therefore, the liquid can be efficiently moved and absorbed in the surface direction and the thickness direction.

  The water-absorbing polymer 20 is a polymer absorbent that absorbs about 10 to 300 times the weight of its own weight and solidifies in a gel state. As the water-absorbing polymer 20, for example, a water-absorbing polymer having antibacterial properties or a load A water-absorbing polymer having a lower liquid permeability can be used. Examples of the water-absorbing polymer having antibacterial properties include trade name Sunfresh ST-900E, manufactured by Sundia Polymer Co., Ltd., and water-absorbing polymers having liquid permeability under load include trade name Sunwet IM- 930, manufactured by Sundia Polymer Co., Ltd. can be mentioned. In the present embodiment, as the water-absorbing polymer 20, a high-performance polymer absorber having antibacterial properties obtained by electrically polymerizing and adhering an antibacterial agent to a polymer absorber such as sodium acrylate and potassium acrylate is used. ing. Thus, the water-absorbing polymer 20 also has antibacterial properties, so that the growth of bacteria in the absorbent body 14 can be suppressed.

  In the present embodiment, the water-absorbing polymer 20 is evenly dispersed in the absorber 14. By being configured in this manner, even when pet urine is dripped from any part on the first surface sheet 12, urine can be efficiently absorbed and retained.

  As the deodorant 21, any known deodorant such as silver ion, citric acid, activated carbon and the like can be used. In this embodiment, hinokitiol is used as the deodorant 21. By including the deodorant 21 in the absorber 14, it is possible to prevent the ammonia odor from leaking out to the surroundings even when urea in the urine absorbed over time is decomposed into ammonia.

  In the present embodiment, the deodorant 21 is evenly dispersed in the absorber 14. By being configured in this way, it is possible to prevent the ammonia odor from leaking out to the surroundings even if the pet's urine is dripped from any part on the first surface sheet 12.

  The thicknesses of the first absorption region 15 and the second absorption region 16 are not particularly limited. For example, the ratio of the thickness T1 of the first absorption region 15 to the thickness T2 of the second absorption region 16 is as follows. In the present embodiment, the thickness of the first absorption region 15 is set to 2 mm, and the thickness T2 of the second absorption region 16 is set to 1 mm. The thickness T1 of the first absorption region 15 here refers to the distance from the surface facing the first absorption region 15 of the liquid-impervious sheet 17 to the inner surface facing the absorber 14 of the first topsheet 12, The thickness T2 of the absorption region 16 refers to the distance from the surface facing the second absorption region 16 of the non-liquid-permeable sheet 17 to the inner surface facing the absorber 14 of the second topsheet 13. When laid in the excretory container 11, the first absorption region 15 on the first surface sheet 12 side facing the pet absorbs more urine from the pet than the second absorption region 16 provided below in the vertical direction. There is a need to. Therefore, by providing the thickness T1 of the first absorption region 15 larger than the thickness T2 of the second absorption region 16 within the above range, all the excreted urine can be absorbed without providing an extra absorber 14. Can do.

  Moreover, when forming the thickness T1 of the 1st absorption area | region 15 which is one absorption area thicker than the thickness T2 of the 2nd absorption area | region 16 which is the other absorption area like this embodiment, the 1st absorption area | region A colored sheet may be interposed at a position close to the first first surface sheet 12. As described above, the first absorption region 15 on the first surface sheet 12 side facing the pet needs to absorb more urine from the pet than the second absorption region 16. Therefore, by interposing a colored sheet at a position near the first surface sheet 12 of the first absorption region 15 that is thicker than the second absorption region 16 and can absorb a large amount of urine, the first surface sheet 12 And the second surface sheet 13 can be easily distinguished by visual observation, so that it can be easily understood which surface sheet should be laid upward in the vertical direction, and all excreted urine can be absorbed. It can be laid as easily as possible.

  The non-liquid-permeable sheet 17 is a sheet-like member interposed along the surface direction in the absorbent body 14, and the absorbent body 14 is disposed on the first absorbent area 15 on the first topsheet 12 side and the second topsheet 13 side. The second absorption region 16 is provided so as to be partitioned. Further, the end surface 24 of the non-liquid-permeable sheet 17 facing the long side direction and the short side direction of the pet urine absorber 10 is provided apart from the first surface sheet 12 over the entire circumference in the surface direction, and the non-liquid-permeable sheet 17. A continuous region 23 is formed between the first surface sheet 12 and the first surface sheet 12. The non-liquid-permeable sheet 17 can be formed using a non-liquid-permeable and flexible sheet, and a polyethylene sheet is used in the present embodiment. Since the non-liquid-permeable sheet 17 is non-liquid-permeable, even when urination penetrates the first absorption region 15 of the absorbent body 14 from the first surface sheet 12 side, it is once blocked by the non-liquid-permeable sheet 17. Most of the urination is absorbed and held in the first absorption region 15. Therefore, when a part of the urine is guided to the bottom part 11a along the inner surface of the peripheral wall 11b of the excretory container 11, the second absorption region 16 can have a sufficient liquid absorption force. Therefore, urination can be absorbed from both sides of the first surface sheet 12 side and the second surface sheet 13 side.

  In addition, since the non-liquid-permeable sheet 17 has flexibility, even if the pet rides on the pet urine absorbing device 10 to urinate, and the pet urine absorbing device 10 is deformed by the weight of the pet, Since it does not break, the first absorption region 15 and the second absorption region 16 can always be partitioned.

  The continuous region 23 is formed between the end surface 24 of the non-liquid-permeable sheet 17 facing the long side direction and the short side direction of the pet urine absorber 10 and the first surface sheet 12. The width W3 of the continuous region 23, which is the distance from the end surface 24 of the non-liquid-permeable sheet 17 to the first surface sheet 12, is not particularly limited. For example, it is continuous with the width W1 in the long side direction of the pet urine absorber 10 described later. The ratio of the area 23 to the width W3 is selected within a range of 100: 1 to 100: 8, and the ratio of the width W2 in the short side direction of the pet urine absorber 10 described later to the width W3 of the continuous area 23 is 100. Is selected within the range of 2 to 100: 11, and the width W3 of the continuous region 23 is selected within the range of 5 to 30 mm. In the present embodiment, the width W3 of the continuous region 23 is configured to be 5 to 10 mm.

  By forming the continuous region 23 in this way, for example, even when a pet urinates at the peripheral portion of the pet urine absorber 10, the absorption from the one absorption region to the other through the continuous region 23. Since urination penetrates into the region, urine penetrates from the absorption region on the side where urination was performed before the amount of urination exceeds the absorption capacity near the periphery of the absorption region on the side where urination was performed to the other absorption region Can be held. Therefore, urination can be prevented from leaking out from the end of the pet urine absorber, and the leaked urine can be prevented from reaching the bottom of the excretory container 11.

  The external shape and external dimensions of the pet urine absorber 10 are not particularly limited. For example, the external shape has a width W1 in the long side direction, a width W2 in the short side direction perpendicular to the long side direction, and an overall height T3. The plane shape is a rectangular sheet, the width W1 in the long side direction is 350 to 950 mm, the width W2 in the short side direction perpendicular to the long side direction is 330 to 650 mm, and the total height T3 is 30 to 340 mm. .

  Moreover, you may form in the surface layer which faces the 1st surface sheet 12 and the 2nd surface sheet 13 of the absorber 14 by embossing in the state where the fine recessed part and convex part were alternately adjacent to the surface direction. For example, the thickness from the front-end | tip part of the convex part of a surface layer to the surface of the side which is not embossed of the absorber 14 is formed in the range of 1 mm or more and 3 mm or less, and the emboss of the absorber 14 is carried out from the surface part of the bottom part in a recessed part. The thickness up to the unprocessed surface is formed to be 70% or more and 80% or less of the thickness from the tip of the convex portion of the surface layer to the non-embossed surface of the absorbent layer. Thus, compared with the case where the surface layer of the absorber 14 is flat by forming the concave portions and the convex portions uniformly distributed on the surface layer facing the first surface sheet 12 and the second surface sheet 13. Thus, the surface area per unit area in the surface direction of the surface of the surface layer is about 1.3 times.

  In the present embodiment, the thickness T1 of the first absorption region 15 is set to be greater than the thickness T2 of the second absorption region 16, but the thickness T1 of the first absorption region 15 and the thickness T2 of the second absorption region are equal. It is good also as thickness. By doing so, an equal amount of urination can be absorbed in either region. Therefore, when the pet urine absorbing device 10 is laid on the excretion container 11, the first surface sheet 12 faces upward. There is no need to install. In other words, it can be laid in the excretion container without confirming which surface faces upward. Therefore, laying of the pet urine absorber 10 can be facilitated.

  Further, the dispersion rate of the water-absorbing polymer 20 in the absorbent body 14 is not particularly limited, but is preferably included in the range of 8 g to 30 g per m 2. By being included in such a range, urination can be uniformly absorbed.

  Moreover, in this embodiment, although the deodorizer 21 is disperse | distributed uniformly in the absorber 14, it sprays on the both surfaces which face the 1st and 2nd absorption area | regions 15 and 16 of the liquid non-permeable sheet 17. It may be configured. By doing in this way, since it can suppress that the deodorizer 21 evaporates, even if it is a case where the pet urine absorber 10 is preserve | saved for a long period of time, a deodorizing effect is maintained in a suitable state. be able to.

  In the present embodiment, the width W3 of the continuous region 23 is formed non-uniformly. However, the present invention is not limited to such a form, and the width W3 of the continuous region 23 may be formed uniformly. Further, the width W3 of the continuous region 23 on the long side of the pet urine absorber 10 is uniformly formed to a predetermined length, and the width W3 of the continuous region 23 on the short side of the pet urine absorber 10 is absorbed into the pet urine absorber. The width may be longer or shorter than the width of the continuous region 23 on the long side of the tool 10.

  In the present embodiment, the continuous region 23 is formed on both the long side and the short side of the pet urine absorber 10, that is, is formed over the entire circumference of the absorbent body 14, but the range in which the continuous region 23 is formed. However, the continuous region 23 may be formed only on one of the long side and the short side of the pet urine absorber 10.

  Moreover, you may provide the double-sided tape which is a tape-shaped member which has an adhesion layer on both surfaces in the other surface on the opposite side to the one surface which faces the absorber 14 of the 2nd surface sheet 13. FIG. When a double-sided tape is provided on the other surface of the second surface sheet 13, one adhesive layer is stuck so as to face the other surface of the second surface sheet 13, and the other adhesive layer has a release paper. Alternatively, a release film is attached so as to be peelable. With this configuration, when the pet urine absorbing device 10 is laid, the release paper or release film is peeled off from the other adhesive layer, and the other adhesive layer from which the release paper or release film is peeled off is the floor surface or excretion. This is a case where the pet moves on the pet urine absorbing device 10 by laying the pet urine absorbing device 10 at a desired position in the floor or the excretory container 11 so as to face the bottom of the container 11. However, it is possible to prevent the pet urine absorber 10 from being moved from a desired position.

  Further, the adhesive tape is not limited to the second surface sheet 13, and can be formed on the first surface sheet 12 in the same manner. The shape, size, number, etc. of the double-sided tape to be provided are not particularly limited. For example, one to two near the center of the surface of the first or second surface sheet 12, 13 on which the double-sided tape is provided. One may be provided.

  FIG. 3 is a view showing a state where the dog 22 as a pet is urinating the pet urine absorber 10 of the present embodiment. The pet urine absorber 10 of the present embodiment is used while being laid in the excretion container 11 and excretes urine toward the surface of the pet facing the upper surface of the first surface sheet 12 of the pet urine absorber 10.

  When urination is performed in the vicinity of the peripheral wall portion of the excretory container 11, a part of the excreted urine is dropped on the surface facing the upper side of the first surface sheet 12, and from the excretion area of the first surface sheet 12. While spreading to the periphery, the first absorbent region 15, which is the region of the absorbent body directly below the excretory region, penetrates in the thickness direction and the surface direction by capillary action, reaches the non-liquid-permeable sheet 17, and the infiltrated region in the surface direction And penetrates into the second absorption region through the continuous region 23 and is retained. Further, the remaining urine is scattered on the peripheral wall 11 b of the excretion container 11 and reaches the bottom 11 a of the excretion container 11 without being absorbed by the first absorption region 15. The urine that has reached the bottom portion 11 a of the excretory container 11 penetrates from the second surface sheet 13 into the second absorption region 16 in the thickness direction and the surface direction by the capillary action at the bottom portion 11 a of the excretory container 11, and enters the non-liquid-permeable sheet 17. It reaches and is infiltrated and held while expanding the infiltration area in the plane direction. In this way, urine is scattered on the peripheral wall 11b of the excretory container 11 depending on the position or posture at the time of excretion of the pet, and the urine scattered on the peripheral wall 11b is guided to the bottom 11a along the inner surface of the peripheral wall 11b. Moreover, since urination can be absorbed in the bottom part 11a, urination can be prevented from remaining in the bottom part 11a of the excretion container 11.

  When urination is performed near the center of the excretory container 11, the excreted urine is dropped on the surface facing the upper side of the first surface sheet 12 and from the excretion area of the first surface sheet 12 to the surroundings. While spreading, it penetrates into the first absorption region 15, which is the region of the absorbent body directly below the excretion region, by the capillary phenomenon in the thickness direction and the surface direction, reaches the non-liquid-permeable sheet 17, and expands the infiltration region in the surface direction The infiltration region is further infiltrated and held in the second absorption region 16 through the continuous region. Therefore, the pet urine absorber 10 of the present embodiment can absorb all of the excreted urine regardless of the position or posture of the pet during excretion.

  Moreover, the pet urine absorber 10 of this embodiment can be used not only by laying in the excretory container 11 as described above but also by laying directly on the floor. When laying directly on the floor and using it, the first surface sheet 12 is laid so as to face the pet. That is, the first absorption region 15 is laid so as to be vertically higher than the second absorption region 16. By laying in this way, it is possible to absorb all the excreted urine without providing an extra absorber 14.

  Further, when the pet is laid directly on the floor and used, even if the pet urinates at the peripheral portion of the pet urine absorbing device 10, the one absorbent region to the other absorbent region via the continuous region 23 Urinate penetrates into the other absorption area from the absorption area on the side where urination was performed before the amount of urination exceeds the absorption capacity near the periphery of the absorption area on the side where urination was performed. Can do. Thus, urination can be prevented from leaking out from the end of the pet urine absorber, and the leaked urine can be prevented from reaching the floor surface.

  Further, even if the leaked urine reaches the floor surface, the second surface sheet 13 facing the floor surface also has liquid permeability, so that the second absorption from the second surface sheet 13 on the floor surface. The region 16 penetrates in the thickness direction and the surface direction by capillary action, reaches the non-liquid-permeable sheet, and penetrates and is retained while expanding the infiltration region in the surface direction. Therefore, leaked urine can be prevented from remaining on the floor surface, and urea in the urine can be decomposed into ammonia with the passage of time, and ammonia odor can be prevented from being generated.
