JP6280430B2 - Pet sheet and pet toilet system using the same - Google Patents

Description

  The present invention relates to a pet sheet such as a cat or a dog, and a pet toilet system using the same.

  Conventionally, when pets such as dogs and cats are raised in a house, as pet toilets for absorbing excrement such as urine excreted by pets, for example, pet sheets are directly formed directly on the floor Or those described in Patent Documents 1 and 2. The pet toilets described in Patent Documents 1 and 2 divide the toilet body into upper and lower parts by a partition member having a liquid-permeable structure such as a spider and form a toilet bed such as water-resistant cat sand in the upper layer portion. A granular material is accommodated, and pet sheets are arranged on the tray in the lower layer part. The excreted urine passes through the water-resistant granular material accommodated in the upper layer portion and is absorbed by the pet sheet.

  By the way, since pets, such as a cat and a dog, have the habit of excreting in the fixed place of the toilet bed for pets, only a part of pet sheets may be used. For this reason, the pet sheet may be reused by changing the front and back of the pet sheet so that the unclean part comes to the place where the pet urinates.

  By reusing such a pet sheet, a portion of the pet sheet that does not absorb urine can be used effectively, and the use period of the pet sheet can be extended. In particular, the toilet for pets described in Patent Document 2 is configured such that a tray for storing pet sheets is pulled out from the front of the toilet body and removed, and can be accommodated in the toilet body by changing the front and rear positions. The pet sheets can be easily replaced in the front-rear direction without taking them out of the tray, and the replacement work can be performed hygienically.

  However, even if urine is absorbed in a part of one side of a pet sheet, if it is left for a long time in a state where urine is absorbed, the remaining areas other than the part that directly absorbs urine are apparently absorbed. However, there is a problem that urine is diffused inside the absorbent body and can no longer exhibit the sufficient absorbency inherent in pet sheets. If it is reused in a state where such sufficient absorbency cannot be exhibited, there is a problem that urine leaks, the floor and tray become dirty, and bad odor is likely to occur. Furthermore, since it is used indoors, it also feels uncomfortable hygienically.

  Accordingly, it is an object of the present invention to provide a pet sheet which is an improvement over the above-described prior art.

  The present invention is a pet sheet comprising a liquid-permeable top sheet, a liquid-impermeable back sheet, and two rectangular absorbent bodies disposed between the two sheets, and the two absorbent bodies Are arranged side by side, and a liquid-impervious leak-proof sheet is arranged between the two absorbers, and the leak-proof sheet has two ends of the leak-proof sheet. It is arranged and fixed on one of the absorbers, and the other end of the leak-proof sheet is fixed in contact with the back sheet to provide a pet sheet separating the two absorbers. is there. The term “on the absorber” means the surface of the absorber on the surface sheet side.

  In addition, the present invention includes a toilet body, a pet toilet that includes a partition member that divides the toilet body into an upper layer portion and a lower layer portion, and stores granular materials forming a toilet bed in the upper layer portion, and the pet A pet toilet system having the pet sheet used in a pet toilet, wherein the pet sheet provides a pet toilet system accommodated in the lower layer portion of the pet toilet It is.

  According to the present invention, floors and trays are hardly soiled, odor is hardly generated, and it is hygienic and economical.

Hereinafter, a preferred first embodiment of the pet sheet of the present invention will be described with reference to FIGS. The rectangular shape of the present invention includes a square having four equal sides, and the short direction in this case is the direction in which the absorbent bodies divided in the pet sheet are arranged in parallel.
The pet sheet 1A of the first embodiment (hereinafter also referred to as “sheet 1A”) has a liquid-permeable top sheet 2, a liquid-impermeable back sheet 3, and a rectangular shape disposed between both sheets. Two absorbers 4, 4 'are provided. And the two absorbers 4 and 4 'are juxtaposed, and in the sheet 1A, they are juxtaposed in the X direction. The X direction in the figure is the same direction as the short direction of the absorbers 4 and 4 ', and is also the same direction as the longitudinal direction of the sheet 1A. The Y direction in the figure is the same direction as the longitudinal direction of each absorber 4, 4 ', and is also the same direction as the short direction (width direction) of the sheet 1A. The Z direction in the figure is the thickness direction.

  As shown in FIG. 1, the sheet 1 </ b> A is formed in a rectangular shape that is long in the X direction in plan view. The sheet 1A has a length in the X direction of about 300 mm to 600 mm, and a length in the Y direction of about 200 mm to 500 mm. Further, the thickness in the Z direction of the sheet 1A is formed to be about 1.0 mm to 15 mm. The thickness is measured by photographing the cross section with an electron microscope or an optical microscope in a non-pressurized state.

  As shown in FIGS. 1 and 2, the surface sheet 2 is formed in a long rectangular shape in the X direction in the sheet 1 </ b> A. As will be described later, the top sheet 2 is larger than the two absorbers 4 and 4 ′ juxtaposed in the X direction, and extends from the periphery of the two absorbers 4 and 4 ′ juxtaposed. In the longitudinal direction (X direction) of the sheet 1A, the surface sheet 2 has surface sheet extending portions 21 and 21 extending from both ends of the two absorbers 4 and 4 'arranged side by side. In the short direction (Y direction), there are short side surface sheet extending portions 23, 23 extending from both ends of the two absorbers 4, 4 ′ arranged side by side. Thus, the top sheet 2 is formed in a rectangular shape extending outward from both ends in the X direction of the absorber 4 and both ends in the Y direction of the absorber 4.

For example, when the sheet 1A is used in a pet toilet 101, which will be described later, the handle sheet of the owner (when the sheet 1A is set in the pet toilet 101 or when the sheet 1A after urine absorption is replaced) In addition, the material may be an economical material in consideration of the sheet strength when rolled and discarded) and liquid permeability, and may be a general low-basis weight liquid-permeable nonwoven fabric. From the economical viewpoint, the liquid-permeable nonwoven fabric used for the top sheet 2 preferably has a basis weight of 50 g / m ² or less, and more preferably 30 g / m ² or less. The said nonwoven fabric should just be a liquid-permeable nonwoven fabric manufactured by a well-known technique.

  As shown in FIGS. 1 and 2, the back sheet 3 is formed in a rectangular shape that is long in the X direction, and is formed in the same shape and size as the top sheet 2. The back sheet 3 is larger than the two absorbers 4 and 4 ′ juxtaposed in the X direction, and extends from the periphery of the two absorbers 4 and 4 ′ juxtaposed. In the longitudinal direction (X direction) of the sheet 1A, the back sheet 3 has back sheet extending portions 31 and 31 extending from both ends of the two absorbers 4 and 4 ′ arranged side by side. In the short direction (Y direction), there are short side back sheet extending portions 33 and 33 extending from both ends of the two absorbers 4 and 4 ′ arranged side by side. Thus, the back sheet 3 is formed in the same shape and size as the top sheet 2 and has a rectangular shape extending outward from both ends in the X direction of the absorber 4 and both ends in the Y direction of the absorber 4. Is formed.

For example, when the sheet 1A is used for a pet toilet 101, which will be described later, the back sheet 3 may be a film made of polyethylene or the like that is usually used, considering the handling and liquid impermeability of the owner. That's fine. From the economical viewpoint, the liquid-impermeable film used for the back sheet 3 preferably has a basis weight of 40 g / m ² or less, and more preferably 25 g / m ² or less.

  As shown in FIGS. 1 and 2, the two absorbers 4 and 4 ′ are juxtaposed in the short direction (X direction) of each absorber 4 and 4 ′. The two absorbers 4 and 4 ′ are arranged between the top sheet 2 and the back sheet 3 in a state of being juxtaposed in the X direction. Each absorber 4, 4 'is formed in a rectangular shape that is long in the Y direction, as shown in FIGS. Each absorber 4, 4 'has a length in the Y direction of about 120 mm to 430 mm, and a length in the X direction of about 80 mm to 280 mm. The thickness of each absorber 4, 4 'in the Z direction is about 0.5 mm to 10 mm. The distance between the two absorbent bodies 4 and 4 ′ included in the sheet 1 </ b> A is preferably 10 mm or more and 50 mm or less, and more preferably 20 mm or more and 30 mm or less. As described above, the absorber 4 and the absorber 4 ′ have the same shape and the same size and the same configuration. However, for ease of explanation, one absorber is referred to as “absorber 4”. age. The other absorber will be described as “absorber 4 ′”.

  The type of each absorber 4, 4 ′ is not particularly limited as long as it has liquid absorbency such as urine. For example, an absorbent core made of a superabsorbent polymer, fluff pulp or the like is used for paper (mounting paper). , And the like wrapped with a core wrap sheet made of nonwoven fabric or the like. For example, those formed by covering the entire absorbent core in which the superabsorbent polymer is dispersed and arranged in the fluff pulp aggregate with a core wrap sheet made of a thin mount can be preferably used. The superabsorbent polymer is used in a state of being mixed in the fluff pulp, or is dispersed on the back sheet 3 side, layered and inserted in the center in the thickness direction, or a means such as forming a polymer sheet by a known means. May be partially arranged. In addition, the form which does not contain a superabsorbent polymer may be sufficient. In the sheet 1 </ b> A, absorbent bodies 4 and 4 ′ in which an absorbent core formed by inserting a superabsorbent polymer in a layered manner and wrapped with a core wrap sheet are used in the center of the fluff pulp aggregate in the Z direction. Yes. Hereinafter, the two absorbers 4 and 4 'of the sheet 1A will be described in detail.

  As the two absorbent bodies 4 and 4 ′, an absorbent body formed by wrapping a rectangular absorbent core 41 with a core wrap sheet 44 may be prepared separately, but the sheet 1 </ b> A is shown in FIG. 3. In this way, one absorbent body formed by wrapping a rectangular absorbent core 41 long in the X direction with a core wrap sheet 44 is cut at the center in the X direction and divided into two absorbent bodies 4. 4 'is formed. Here, the absorbent core 41 is formed by spraying and laminating the superabsorbent polymer 43 between the aggregate 42u on the upper layer side of the fluff pulp and the aggregate 42d on the lower layer side of the fluff pulp. From the viewpoint of smooth urine absorption and transfer of urine to the superabsorbent polymer 43, the basis weight of the upper layer side assembly 42u is formed lower than the basis weight of the lower layer assembly 42d. Is preferred. The initial one absorbent body is formed by covering one absorbent core 41 entirely with a core wrap sheet 44 except for both ends in the Y direction.

  The core wrap sheet 44 is composed of an upper layer core wrap sheet 44u and a lower layer core wrap sheet 44d having different dimensions as shown in FIG. The upper core wrap sheet 44u is formed so that the lengths in the X direction and the Y direction substantially coincide with the lengths of the absorbent core 41 in the X direction and the Y direction. The lower layer core wrap sheet 44d has a length in the Y direction substantially equal to the length in the Y direction of the absorbent core 41, and the length in the X direction is longer than the length in the X direction of the absorbent core 41. It is formed wider than the core wrap sheet 44u. The upper core wrap sheet 44u is disposed to face the upper surface of the absorbent core 41. The lower core wrap sheet 44d is arranged to face the lower surface of the absorbent core 41, and a portion extending from both ends in the X direction of one absorbent core 41 covers the upper surface of the absorbent core 41. It is wound up on the upper surface of the upper layer core wrap sheet 44u. In this way, one initial absorbent body of the sheet 1A is formed. Next, at the center in the X direction of one absorber, it is cut in parallel along the Y direction and divided to form two rectangular absorbers 4, 4 'that are long in the Y direction. In the two absorbent bodies 4 and 4 ′ thus formed, the end of the absorbent core 41 on the divided side in the X direction is not covered with the core wrap sheet 44 (lower layer core wrap sheet 44 d). . In addition, a deodorizer, an antibacterial agent, a fragrance | flavor, etc. can be added to the absorptive core 41 as needed.

  The two absorbent bodies 4 and 4 ′ of the sheet 1A will be described in more detail. As shown in FIG. 3, the upper layer side assembly 42u constituting each absorbent body 4 and 4 ′ has an X direction. Compared with the thickness in the Z direction of the end portion on the side covered with the core wrap sheet 44 (lower layer core wrap sheet 44d) in the X direction, the end portion on the divided side in FIG. It is getting thinner. Specifically, the inner side of each assembly 42u in the X direction extends over the entire side portion along the Y direction of the upper-layer assemblies 42u and 42u juxtaposed in the X direction. The end portions gradually become thinner inward in the X direction, in other words, toward the center of the juxtaposed upper-layer assemblies 42u and 42u.

  As shown in FIGS. 1 and 2, a liquid-impermeable leak-proof sheet 9 is disposed between the two absorbent bodies 4 and 4 ′. The leak-proof sheet 9 has one end 91 in the X direction of the leak-proof sheet 9 arranged and fixed on one of the two absorbent bodies 4 and 4 ′, and the other end of the leak-proof sheet 9. 92 is fixed in contact with the back sheet 3 and separates the two absorbers 4 and 4 ′. The leak-proof sheet 9 of the sheet 1 </ b> A is a rectangular sheet that is long in the Y direction, and is longer than the length in the Y direction of each absorber 4, 4 ′, and between both ends in the Y direction of each of the top sheet 2 and the back sheet 3. It extends in a strip shape parallel to the Y direction. One end 91 in the X direction of the leak-proof sheet 9 needs to have a width of about 10 mm to 50 mm, more preferably about 15 mm to 30 mm, more preferably about 15 mm to 30 mm. The length (width) in the X direction is preferably about 20 mm to 80 mm, and more preferably about 30 mm to 50 mm. In addition, it is preferable that the length of the leak-proof sheet 9 in the Y direction is the same as the length of the sheet 1A in the Y direction. The term “on the absorbent body 4” refers to one surface of the absorbent body 4 on the surface sheet 2 side.

  The leakproof sheet 9 of the sheet 1A will be described in detail. As shown in FIGS. 1 and 2, one end 91 in the X direction of the leakproof sheet 9 is one of the two absorbent bodies 4 and 4 ′. 4 and the top sheet 2 are arranged and fixed. The other end 92 in the X direction of the leak-proof sheet 9 is disposed between the two absorbers 4 and 4 ′ and fixed in contact with the back sheet 3. By arranging the leak-proof sheet 9 in this way, the two absorbers 4, 4 'are separated.

  As shown in FIGS. 1 and 2, the sheet 1 </ b> A having the above-described configuration has a top sheet extending portion 21 and a back sheet extending portion 31 bonded to each other at both ends in the X direction, It extends to. Specifically, the top sheet 2 and the absorber 4 and the back sheet 3 and the absorber 4 are joined by a joining means such as a hot melt adhesive. And in each of the both ends side of the X direction of the sheet 1A, the surface sheet extension part 21 and the back sheet extension part 31 are joined by joining means such as hot melt adhesive to form the side flap 5. Yes. Each side flap 5 extends outward in the X direction. The side flap 5 formed by joining the top sheet extending portion 21 and the back sheet extending portion 31 is preferably formed to have a width in the X direction of 10 mm or more and 40 mm or less, and is formed by 20 mm or more and 30 mm or less. More preferably. The hot melt adhesive may be applied in the form of a line, a surface, a dot, a spiral, or a mist.

Forming a flap. Each flap formed by joining the short side surface sheet extension part 23 and the short side back sheet extension part 33 extends outward in the Y direction, and the width in the Y direction is 10 mm or more and 40 mm or less. It is preferably formed, more preferably 20 mm or more and 30 mm or less.

The effect at the time of using the sheet 1A of 1st Embodiment of this invention mentioned above is demonstrated.
The sheet 1A is used by being placed directly on the floor, or housed in a pet toilet 101 and used as a pet toilet system 100A.

First, the case where the sheet 1A is placed directly on the floor and used will be described.
Pets such as dogs and cats always tend to be excreted at a fixed place. For example, urination is performed at a predetermined place of one of the two absorbent bodies 4 and 4 'of the pet sheet 1A. In the sheet 1A, since the two absorbent bodies 4 and 4 'are separated by the leak-proof sheet 9, the urine absorbed by one of the absorbent bodies 4 is used as the leak-proof sheet 9. It cannot move to the other absorber 4 'beyond. Moreover, for example, when it is customary to urinate to a predetermined place of the other absorbent body 4 ′, urine absorbed by the other absorbent body 4 ′ passes over the leak-proof sheet 9 to the one absorbent body 4. It cannot be migrated. Therefore, the absorbent body on the non-stained side can exhibit sufficient absorbency, and the front and back of the sheet 1A are exchanged so that the non-stained absorbent body comes to the place where the pet urinates and is reused. Even so, urine is hard to leak out and the floor is hard to get dirty. Since the floor is hardly soiled in this way, it is difficult to generate bad odors and is hygienic. Moreover, since the sheet 1A can be reused in this way, it is economical.

  In particular, the upper-layer assembly 42u constituting each absorber 4, 4 'included in the sheet 1A has a reduced thickness in the Z direction at the end portion on the divided side in the X direction. Therefore, urine excreted in the vicinity of the center of the sheet 1A passes through the top sheet 2 and is further guided to the center by the leak-proof sheet 9, so that one of the absorbent bodies 4 or the other absorbent body 4 ' It becomes easy to be absorbed by either. Unfortunately, even if the excreted urine spreads over both absorbers 4 and 4 ′, diffusion of urine between the absorbers 4 and 4 ′ is blocked by the leak-proof sheet 9 as described above. Therefore, the absorption amount of each absorber 4, 4 ′ can be sufficiently secured.

  Moreover, it is preferable that the leak-proof sheet 9 with which the sheet 1A is provided is colored. When the leak-proof sheet 9 is colored, it is easy to distinguish the front and back of the sheet 1A, and the effect of improving the feeling of use is achieved.

In other words, urine is fed to one of the two absorbers 4 and 4 ′ juxtaposed in the X direction provided to the pet sheet 1A on the partition member 103 positioned above the leak-proof sheet 9 provided to the pet sheet 1A. A urine guide member 107 for guiding is provided so as to extend along the leak-proof sheet 9. Here, the leak-proof sheet 9 is formed in parallel to the Y direction. In the pet toilet system 100A, the urine guide member 107 is provided above (upper layer portion A) above the partition member 103 (the bottom portion 151c of the inner container 105), as shown in FIG.

  The urine guide member 107 of the pet toilet system 100A is attached to the upper surface (surface on the upper layer portion A side) of the partition member 103, as shown in FIGS. 4 and 6, and the boundary between adjacent sheets 1A and 1A ′ And is continuous over the entire length in the X direction in the inner container 105, that is, between the pair of side wall portions 151 a and 151 a facing the inner container 105. The urine guide member 107 does not have the through hole 131 and does not have a liquid passage structure.

  As shown in FIG. 6, the urine guide member 107 includes two absorbent bodies 4, 4 ′ arranged side by side provided on the sheet 1 A from the top located directly above the leak-proof sheet 9 provided on the pet sheet 1 A. Slopes 171 and 171 extending obliquely downward toward the bottom. Specifically, the urine guide member 107 is formed in a substantially isosceles triangle shape in a cross-sectional view along the longitudinal direction of the toilet body 102, and the top of the isosceles triangle shape portion is formed on the leak-proof sheet 9. The lower part of the isosceles triangular portion is located directly above, and is joined to the upper surface of the partition member 103. The angle α formed by the two inclined surfaces 171 and 171 is preferably 28 ° or more and 176 ° or less, and 45 ° or more and 160 ° or less from the viewpoint of inducing urine to one of the two absorbers 4 and 4 ′. More preferably.

  The material of the constituent members of the pet toilet 101 (partition member 103, outer container 104, inner container 105, accommodating portion 106, urine guide member 107, etc.) is not particularly limited as long as it has corrosion resistance. For example, polypropylene, polyethylene, polyethylene terephthalate, vinyl chloride, acrylonitrile-butadiene-styrene copolymer (ABS), etc. preferable. Moreover, it is more preferable to use the constituent member of the pet toilet 101 whose surface has been subjected to water repellent processing or antibacterial processing.

  As the granular material 109 accommodated in the upper layer portion A, a granular material used as cat sand or toilet sand in the technical field can be used without particular limitation. The granular material 109 is preferably configured to include one or more components such as a pulverized material of a plant-derived material, a synthetic resin, and a clay mineral, and may be a molded product. The shape of the granular material 109 is not limited to a cylindrical shape as shown in FIG. 8, and may be, for example, a sphere, a cube, a rectangular parallelepiped, or the like. As the granular material 109, the excrement treating agent described in Japanese Patent No. 3788625 according to the previous application of the present applicant can also be used.

  As shown in FIG. 6, the pet toilet system 100 </ b> A lays an appropriate amount of granular material 109 on the entire upper surface of the partition member 103 to form a layer of granular material 109 on the upper layer portion A, and also accommodates the lower portion B. A sheet 1A is accommodated in 106 and used. The granular material 109 accommodated in the upper layer portion A quickly passes the urine excreted by the pet, and the passed urine passes through the through hole 131 of the partition member 103 having a liquid passage structure, and the pet sheet in the lower layer portion B It falls onto 1A and is absorbed by pet sheet 1A.

  As described above, pets such as dogs and cats tend to be excreted at a fixed place. For example, one of the two absorbent bodies 4 and 4 ′ provided in the pet sheet 1 </ b> A has one absorbent body 4. When it is customary to urinate to the position of the granular material 109 disposed on the entire upper surface of the partition member 103 corresponding to a predetermined place, the granular material 109 quickly passes the urine excreted by the pet, and this urine that has passed through. Falls on one absorber 4 of the sheet 1A of the lower layer portion B through the through hole 131 of the partition member 103 having a liquid passage structure and is absorbed. In the sheet 1A, the two absorbent bodies 4 and 4 'are separated by the leak-proof sheet 9, so that the urine absorbed by the one absorbent body 4 passes through the leak-proof sheet 9 and the other absorbent body 4'.

In addition, for example, when it is customary to urinate to the position of the granular material 109 disposed on the entire upper surface of the partition member 103 corresponding to a predetermined location of the other absorber 4 ′, the granular material 109 is excreted by the pet. The passing urine is quickly passed, and the passed urine is dropped and absorbed onto the other absorbent body 4 ′ of the sheet 1A of the lower layer portion B through the through hole 131 of the partition member 103 having a liquid passage structure. The urine absorbed by the other absorber 4 ′ cannot move to the one absorber 4 beyond the leak-proof sheet 9. Therefore, the absorbent body on the side that is not soiled can exhibit sufficient absorbency. Accordingly, the sheet 1A can be reused by pulling out the accommodating portion 106 from the toilet body 102 and replacing the front and back of the sheet 1A so that the absorbent body on the non-dirt side is placed where the pet urinates. So it is economical. In addition, as described above, the absorbent body on the non-stained side can exhibit sufficient absorbency, and even when the sheet 1A is reused, urine is hardly leaked out and the container 106 is not easily soiled. Thus, since the accommodating part 106 is hard to be polluted, a bad smell is hard to generate and it is hygienic.

  In particular, as shown in FIG. 6, the pet toilet system 100A is provided with a urine guide member 107 that guides urine to one of the two absorbers 4, 4 'arranged in parallel in the sheet 1A. Therefore, one of the two side-by-side absorbers 4 and 4 ′ provided in the sheet 1 </ b> A disposed on the accommodating portion 106 is more easily contaminated and the other is more difficult to be contaminated. With the absorbent body, the sheet 1A can be reused, is very economical, and is very hygienic.
