Description

In recent years, pets such as dogs and cats have been widely bred indoors, and disposable pet excrement disposal sheets are also known to prevent the pet's urine and feces from soiling the floor. ing. For example, Patent Literature 1 discloses a pet excrement disposal sheet having a water absorbent sheet layer and a waterproof sheet layer disposed so as to be in contact with the lower surface of the water absorbent sheet layer.
Conventional pet excrement disposal sheets are in a state of being wound into a roll as disclosed in Patent Document 1, or in a state of being folded and stored in a packaging bag, and are commercially available. . When folded and stored in a packaging bag, usually a plurality of folded sheets are stacked and stored.

Japanese Utility Model Publication No. 2-127155

  However, in the above-described conventional pet excrement disposal sheet, the sheet taken out from the packaging bag is placed on the floor or a dedicated toilet for pets, and the excretion is made to the pet. Depending on the amount and frequency of excretion of pets, the work of laying a new sheet in the same place usually has to be done several times a day, and it takes time and effort. There was a problem. For this reason, it has been necessary to reduce the processing work burden associated with pet excretion.

  Therefore, the objective of this invention is providing the laminated sheet for pet excrement disposal which can reduce the burden of the excrement disposal work of the breeder accompanying the pet excretion act.

  The present invention provides a pet excrement disposal laminated sheet in which a plurality of excrement disposal sheets are stacked and partially fixed to each other, and the excrement disposal sheets can be separated from each other. Thus, the object is achieved.

  According to the laminated sheet for pet excrement disposal of the present invention, it is possible to reduce the burden of the excrement disposal work of the breeder accompanying the pet excretion act.

Hereinafter, the present invention will be described based on preferred embodiments with reference to the drawings.
FIG. 1 is a plan view showing a partially cutaway laminating sheet 1 for treating pet excrement (hereinafter also simply referred to as a laminating sheet 1) according to an embodiment of the present invention. The excrement disposal sheets 1A, 1B, 1A, 1B are stacked and partially fixed to each other.

  The laminated sheet 1 includes two types of excrement disposal sheets 1A and 1B each having a different size. The excrement disposal sheet 1A and the excrement disposal sheet 1B are shown in FIG. As described above, the laminated sheets 1 are alternately arranged in the thickness direction.

  The laminated sheet 1 has a rectangular shape in plan view, and the four excrement disposal sheets 1A constituting the laminated sheet 1 are disposed on each of the end portions H1 to H3 located on the three sides of the rectangle. 1B, 1A, and 1B have a fixed portion fixed to each other. In the adhering portion, four laminated excrement disposal sheets are integrated by heat fusion.

  The excrement disposal sheet 1A has a perforation 14 for separating the excrement disposal sheets from each other on the center side of the laminate sheet 1 from each of the end portions H1 to H3 of the laminate sheet 1. . Referring to FIG. 1, the center side of the laminated sheet 1 is below the end H1 with respect to the end H1, to the right with respect to the end H2 with respect to the end H2, and at the end H3. Is to the left of the end H3. The perforation 14 is formed in a U-shape as a whole.

The excrement disposal sheet 1B has a longer rectangular side than the excrement disposal sheet 1A, and in a stacked state, a portion extending from one end of the excrement disposal sheet 1A as shown in FIG. have. Other than that, it has the same structure as the excrement disposal sheet 1A, and a perforation 14 similar to the excrement disposal sheet 1A is also formed in the excrement disposal sheet 1B.
The perforation 14 is formed so as to penetrate through the entire thickness direction of the excrement disposal sheets 1A, 1B. In the laminated sheet 1, the perforation 14 of the excrement disposal sheet 1 </ b> A is formed at a position overlapping the perforation 14 of the excrement disposal sheet 1 </ b> B.
The excrement disposal sheet 1A and the excrement disposal sheet 1B have different lengths, but have the same width. Of course, the width of the excrement disposal sheet 1A may be narrower than the width of the excrement disposal sheet 1B.

Each excrement disposal sheet 1A, 1B is composed of an upper layer sheet 11, a lower layer sheet 12, and an absorbent body 13 disposed between the two sheets 11, 12, respectively, such as a hot melt adhesive or the like. The layers are bonded and integrated by an adhesive.
The upper layer sheet 11 and the lower layer sheet 12 have the same shape and size for each excrement disposal sheet 1A, 1B.

  As materials for the upper layer sheet 11 and the lower layer sheet 12 used for the excrement disposal sheets 1A and 1B, the same materials as those conventionally used for this type of product can be used. For example, a liquid-permeable sheet material can be used as the upper layer sheet 11. Examples of the material for the sheet material include various thermoplastic resins such as polyolefin resins such as polyethylene and polypropylene, polyester resins such as polyethylene terephthalate, and polyamide resins. The sheet material made of these materials can be in the form of, for example, a fiber sheet, a film, or a laminate thereof. When the sheet material is composed of a water-repellent material, a hydrophilization treatment with various hydrophilizing agents may be performed.

  When the sheet material is a fiber sheet, either a woven fabric or a non-woven fabric can be used as the fiber sheet. Considering that the pet sheet is disposable, it is preferable to use a non-woven fabric as the fiber sheet from the viewpoint of economy. When using a nonwoven fabric as a fiber sheet, as this nonwoven fabric, a spun bond nonwoven fabric, an air through nonwoven fabric, a spunlace nonwoven fabric, a needle punch nonwoven fabric, a chemical bond nonwoven fabric, etc. can be used, for example. Of these nonwoven fabrics, it is preferable to use a spunbond nonwoven fabric that is a nonwoven fabric having high strength and good liquid permeability.

  Since the said fiber sheet has a space | gap between fibers, it is possible to permeate | transmit a liquid through this space | gap. However, the fiber sheet may be subjected to a hole opening treatment to form a large number of holes regularly or irregularly, thereby further ensuring the permeation of the liquid. In the case where the sheet material is a film, it is necessary to form a large number of apertures regularly or irregularly by subjecting the film to aperture treatment in order to ensure the permeation of the liquid. The openings formed in these fiber sheets and films may be planar or funnel-shaped three-dimensional. In particular, if the openings are three-dimensional, it is advantageous because the liquid absorbed by the absorber does not easily return to the upper layer sheet surface, that is, wetback occurs.

Sheet material forming the upper layer sheet 11, that it is regardless of whether the addition the color is or film is a fiber sheet, a basis weight of 10 to 50 g / m ^2, in particular 15-25 g / m ² Is preferable from the viewpoint of securing sufficient strength of the upper layer sheet 11 and raw material cost and sheet thickness.

As the lower layer sheet 12, a liquid-impermeable film made of a thermoplastic resin can be used. Moreover, you may laminate a nonwoven fabric etc. on this film. Alternatively, as the lower layer sheet 12, a water-repellent sheet material such as a spunbond-meltblown-spunbond nonwoven fabric may be used, and the color thereof does not matter. The lower layer sheet 12 has a basis weight of 10 to 50 g / m ² , in particular 15 to 30 g / m ² , from the viewpoint of ensuring sufficient strength of the lower sheet 12, ensuring sufficient liquid blocking properties, and product It is preferable from the viewpoint of the thickness of the sheet and the handleability.

  As the absorbent body 13, a liquid absorbent material such as fluff pulp, a water absorbent polymer, a mixed product of them can be used. Here, as the water-absorbing polymer, various known polymers can be used without particular limitation. For example, sodium polyacrylate, (acrylic acid-vinyl alcohol) copolymer, sodium polyacrylate cross-linked product, (starch- Acrylic acid) graft copolymers, (isobutylene-maleic anhydride) copolymers and saponified products thereof, polyaspartic acid, and the like. Further, as the fiber material, various known materials can be used without particular limitation. For example, hydrophilic fibers such as pulp fiber, rayon fiber, cotton, and cellulose acetate can be used. These include polyethylene, Polyolefin fibers such as polypropylene, condensation fibers such as polyester and polyamide, and vinyl monomer polymer fibers such as vinyl chloride and vinyl acetate may be mixed.

  In particular, it is preferable to use a mixed fiber of fluff pulp and a water-absorbing polymer from the viewpoint of ensuring a sufficient absorption capacity. When this mixed fiber is used, it is preferable to coat the periphery with an absorbent paper such as tissue paper from the viewpoint of ensuring the shape retention of the mixed fiber and preventing the water-absorbing polymer from falling off. By arranging various colors on the paper, it becomes easy to recognize that the place is a toilet, and it is also effective as an indoor interior.

  The laminated sheet 1 of this embodiment is a packaging bag or container in a state where a plurality of sheets for excrement disposal 1A, 1B, 1A, 1B constituting the laminated sheet 1 are integrally folded and further laminated. It is preferable from the viewpoint of being able to transport, display products, store, etc. in a compact form.

The laminated sheet 1 of the present embodiment can be used by being laid on the floor in a single state, or is used in a state in which the laminated sheet 1 is held by a holder that holds the laminated sheet 1 so as not to move from the original laying position. You can also.
2 and 3 show a state in which the laminated sheet 1 is held by the tray-like holder 2. In FIG. 4, from the laminated sheet 1 in the state held by the holder 2, A state in which the excrement disposal sheets 1A and 1B constituting the laminated sheet 1 are taken out in order from the top is shown.

The usage method of the holder 2 shown in FIGS. 2-4 and the lamination sheet 1 using this holder 2 is demonstrated.
The holder 2 has a tray-like form as a whole, and can accommodate the laminated sheet 1 in a state of being flattened inside, and can fix the peripheral edge of the laminated sheet 1 by sandwiching it from above and below. In this state, it can be used by being placed on an indoor floor made of carpet or carpet.

  As shown in FIG. 2, the holder 2 has a rectangular shape in plan view, and is rounded at four corners. Various materials such as plastic, wood, or ceramic can be used as the material of the holder 2. In FIG. 2, two rectangular broken lines are drawn, but the outer broken line B1 represents the outer shape of the laminated sheet 1, and the inner broken line B2 represents the excrement disposal sheet 1A or 1B. The perforation 14 at the time of separation is shown.

As shown in FIG. 3, the holder 2 includes a bottom portion 21 and a frame portion 22. The bottom portion 21 includes a tray base 21a on which the laminated sheet 1 (in other words, a plurality of excrement disposal sheets 1A and 1B) is placed, and a protruding portion 21b erected from the vicinity of the peripheral edge of the tray base 21a. Have. A groove portion 21b1 is formed on the outer surface of the protrusion portion 21b, and the protrusion 22a of the frame portion 22 is fitted into the groove portion 21b1. The frame portion 22 can be fixed to the bottom portion 21 so as to cover the laminated sheet 1 placed on the tray base 21a. In the fixed state, the frame portion 22 has a peripheral edge portion of the opening portion of the opening portion. The holding portion 22b protruding from the lower surface presses the peripheral edge of the laminated sheet 1 from above, whereby the laminated sheet 1 is stably held in an expanded state.
In FIG. 3, the restraining part 22b of the frame part 22 is in contact with the upper surface of the uppermost excrement disposal sheet 1A. Even if the uppermost excrement disposal sheet 1A is separated, the sheet in the vicinity of the restraining portion 22b is not separated and remains as it is. Therefore, the restraining portion 22b is always a pet that is a laminate of the excrement disposal sheets 1A and 1B. The excrement disposal laminated sheet 1 can be held.
The perforations formed on the excrement disposal sheets 1A and 1B may not be formed on the lowermost excrement disposal sheet 1B. Further, the frame portion 22 may be partly connected to the bottom portion 21 by a hinge or the like, or may be completely removable from the bottom portion 21.

FIG. 4 shows a state in which the excrement disposal sheet 1 </ b> A constituting the uppermost layer of the laminated sheet 1 is separated from the laminated sheet 1 held by the holder 2.
More specifically, the pet breeder holds one end of the excrement disposal sheet 1A after urination of the pet, lifts the excrement disposal sheet 1A while twisting, and the sewing machine of the excrement disposal sheet 1A A state in which the excrement disposal sheet 1A is separated from the remaining excrement disposal sheet 1B while the eyes 14 are broken is shown.
Thus, when the uppermost excrement disposal sheet 1A of the laminated sheet 1 is separated, the next excreta disposal sheet 1B in an unused state appears on the surface. The excrement disposal sheet 1B can also be separated from the other excrement disposal sheets 1A and 1B remaining in the holder 2 in the same manner as the excrement disposal sheet 1A after the excretion of the pet. When gripping one end of the excrement disposal sheets 1A and 1B, a finger is inserted into the arc-shaped cutout portion 2a formed in the frame 22, and the end of the excrement disposal sheet 1A or 1B is picked. Easy to grip.
For example, the laminated sheet 1 of the present embodiment can sequentially separate the excrement disposal sheets 1A and 1B from one surface side in this manner.

The laminated sheet for treating pet excreta of the present invention is also preferably used in combination with a plurality of types of excreta treating sheets having different performances. For example, in the laminated sheet 1 of the embodiment described above, the performance can be made different between the excrement disposal sheet 1A and the excrement disposal sheet 1B.
Examples of the performance to be differentiated include deodorization performance, absorption performance, and surface sheet strength (for example, prevention of scratching caused by dog mischief), and these two or more performances can be varied.
For example, the excrement disposal sheet 1A or 1B having a deodorizing performance and the excrement disposal sheet 1B or 1A having a lower deodorizing performance but a higher absorption performance can be overlapped.
In addition, for pets who often break and tear the sheet during the day, etc., it is also convenient to install a sheet with a strong surface sheet on the top surface according to the time zone. Can be devised.

The difference in the deodorizing performance of the sheet is, for example, 1) a method of varying the blending amount of the perfume component, 2) a method of varying the blending amount of the water-absorbing polymer, 3) blending a water-absorbing polymer having a different amount of absorption per unit 4) When blending wood flour pellets, 5) a method of varying the blending amount, 5) a method combining two or more of these methods, and the like. There is no restriction | limiting in particular as a kind of fragrance | flavor, For example, the various substances of Unexamined-Japanese-Patent No. 2007-229151 can be used.
Moreover, the difference in the absorption performance of a sheet | seat can be expressed as a difference in a total absorption amount by varying the content and kind of a water-absorbing polymer, or the amount of pulp, for example.
Furthermore, the difference in the urine odor (ammonia odor) can be expressed by the content of the water-absorbing polymer.

For example, when the excrement disposal sheets 1A and 1B are replaced twice a day in the morning and night for mutual income or living alone, the excrement disposal sheet 1A is turned into a superabsorbent sheet and the excrement disposal sheet 1B. A sheet excellent in odor is preferably used. In this case, if the laminated sheet 1 composed of the excrement disposal sheets 1A and 1B is installed in the night, the urgent work in the morning is separated from the excrement disposal sheet 1A and discarded. Can end with
The upper layer uses a high-absorbency sheet to absorb a large amount of pet urine discharged in the morning, and the lower layer uses a sheet with excellent deodorizing power for several times during the day. It is necessary to absorb the urine, so that the urine odor will not be bothered when the owner returns home.

  Alternatively, a superabsorbent sheet may be used for the upper layer, and a lower absorbent sheet may be used for the lower layer. The reason why the superabsorbent sheet is used in the upper layer is to absorb the first large amount of urine, and the reason why the normal absorbent sheet is used in the lower layer is to cope with the absorption of urine for about half a day. Absorption performance can be changed by adjusting the amount of pulp and the amount of polymer. Further, a normal deodorant sheet may be used for the upper layer, and a high deodorant sheet may be used for the lower layer. The reason why a normal deodorant sheet is used for the upper layer is to cope with deodorization of urine once in the morning, and a highly deodorant sheet is used for the lower layer because urine excreted several times for a long time during the day. This is to cope with the deodorization. In addition, various combinations can be applied.

In the laminated sheet 1 of the embodiment described above, a plurality of excrement disposal sheets 1A and 1B are overlapped and partially fixed to each other, and the excrement disposal sheets 1A or 1B can be separated. Therefore, depending on the wetness and dirtiness of each excrement disposal sheet, it is possible to reduce the burden of the excrement disposal work of the breeder accompanying the excretion act of the pet by using it separately as appropriate. it can. In particular, in the laminated sheet 1, the excrement disposal sheets 1 </ b> A and 1 </ b> B can be sequentially separated from one side of the laminated sheet 1, so that excrement disposal can be performed more efficiently.
In the above-described embodiment, since the size of the excrement disposal sheet 1A and the excrement disposal sheet 1B are different from each other, it is easy to take out the individual excrement disposal sheets and the excrement disposal process. Since the sheets 1A for waste and the sheets 1B for excrement disposal are alternately stacked, a more efficient method of use is possible with different performances. In addition, since three or more, particularly four or more sheets for excrement disposal are laminated, it is possible to use a full-time housewife who spends a long time with the pet every time after the pet defecates.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not restrict | limited to embodiment mentioned above, It can change suitably.

  For example, in the above-described embodiment, the fixing portions are provided at the end portions H1 to H3 located on the three sides of the rectangular laminated sheet 1, and the perforations are formed in the vicinity of the fixing portions on the three sides. As shown in FIG. 6, the fixing part may be provided only at the end H1 located on one side of the excrement disposal laminated sheet, and the perforation 14 may be provided only in the vicinity of the fixing part. In addition, the fixing portions may be provided at the end portions H2 and H3 located on the two opposite sides of the excrement disposal laminated sheet, and the perforations 14 may be provided only in the vicinity of each of the fixing portions. Moreover, the fixing | fixed part provided in the edge part of the lamination sheet 1 can also be provided in the position spaced apart from the peripheral edge of each excrement disposal sheet | seat by predetermined width (for example, about 0.1-2 cm). Furthermore, the fixing | fixed part of the excrement disposal sheets can also be provided in parts other than the edge part of a lamination sheet.

  In addition, the excrement disposal laminated sheet may be composed of excrement disposal sheets that are laminated with the center points coincided and have the same size. Further, two types of excrement disposal sheets having different sizes may be laminated so that the other excrement disposal sheet extends from each of two opposite sides of the one excrement disposal sheet. . Further, three or more types of excrement disposal sheets having different sizes may be laminated, and even in that case, the amount of extension from one side of the excrement disposal sheet constituting one surface of the laminate sheet However, it can also be laminated so as to gradually increase toward the other surface side of the laminated sheet.

Further, the pet excrement disposal laminated sheet may be composed of a plurality of excrement disposal sheets having the same performance. For example, 3-5 sheets of excrement disposal sheets having a minimum absorption capacity necessary to absorb one, two, or three urinations may be stacked to form a set.
The number of sheets for excrement disposal sheets may be two or three instead of four, or may be about five to ten. The shape of the laminate sheet for pet excrement disposal and the individual excrement disposal sheets constituting it can be a square shape instead of a rectangle, an ellipse or a circle, a rectangle with rounded corners, a rhombus, It can also be a heart shape or the like.

In addition, each excrement disposal sheet is not limited to the upper layer sheet, the lower layer sheet, and the absorbent sheet disposed between the both sheets, and the upper layer sheet having a certain amount of absorption capacity and the leak-proof property. It may consist only of the lower layer sheet it has, or it may be one in which a resin layer is formed on one side of the pulp sheet.
Further, a method for fixing a plurality of excrement disposal sheets to each other may be embossing, an adhesive, or the like instead of heat fusion. Moreover, the method which combined these 2 or more can also be used.

  In the above-described embodiment, the excrement disposal sheet 1A and the excrement disposal sheet 1B are separated by perforation. However, the excrement disposal sheets are separated by a method other than the perforation. It may be made separable. For example, a plurality of excrement disposal sheets may be fixed to each other with such a bonding strength that they can be easily peeled by hand force. In this case, it is preferable that the bonding strength between the excrement disposal sheets in the fixing portion is 10 to 300 g / 30 mm, particularly 20 to 150 g / 30 mm.
