  The invention described in the cited document 1 and the cited document 2 is based on the premise that the dog or cat excretes at the central portion of the pet absorbent sheet. However, dogs or cats rarely urinate in the center of the pet absorbent sheet. In many cases, dogs or cats face backward and excrete urine or the like near the end of the pet absorbent sheet. In such a case, there is a problem that the excrement overflows from the side end of the pet absorbent sheet to the floor or the like.

  In order to solve the above-described problems, the present invention provides a pet absorbent sheet that prevents urine from leaking to the floor even if a dog or a cat excretes in the vicinity of the side end of the pet absorbent sheet. The purpose is to provide.

  The pet absorbent sheet of the present invention is a liquid-impermeable back sheet, an air-through non-woven fabric provided with a protruding portion that protrudes from both side ends of the liquid-impermeable back sheet, It is sandwiched between a liquid-impermeable back sheet and the air-through nonwoven fabric, and comprises a water-absorbing member in which paper fibers and a water-absorbing polymer are sandwiched between tissue papers.

  According to the present invention, even if excretion of a dog or a cat is performed at the end of the pet absorbent sheet, the side of the air-through nonwoven provided on the top of the pet absorbent sheet so as not to soil the floor A protruding portion that protrudes the end portion from the water absorbing member is provided. The air-through nonwoven fabric that protrudes from the water-absorbing member wraps around and is absorbed by the water-absorbing member without the urine or the like performed at the side end flowing directly to the floor or the like.

  The absorbent sheet for pets of the present invention is laminated from the bottom in the order of liquid-impermeable back sheet, tissue paper, paper fiber (pulp), water-absorbing polymer, tissue paper, and air-through nonwoven fabric. The liquid-impermeable back sheet is made of, for example, a polyethylene sheet and made of a material that does not exude excrement such as pet urine. The water-absorbing member laminated in the order of tissue paper, paper fiber (pulp), water-absorbing polymer, tissue paper can store excrement such as urine between paper fiber and water-absorbing polymer. . The air-through nonwoven fabric is of a type that allows air to pass therethrough, and has a protruding portion that protrudes larger than both side end portions of the liquid-impermeable back sheet and the water absorbent member at both side end portions thereof. .

  Since the air-through nonwoven fabric has a protruding portion that protrudes from both end portions of the liquid-impermeable back sheet and the water-absorbing member, the pet excretes urine and the like in the vicinity of the end portion of the pet absorbent sheet. Even if it goes, the said excretion etc. will be transmitted from the said protrusion part to a back surface, and will be absorbed by the said water absorbing member. In addition, since most of the excreta and the like are absorbed by the water absorbent member, the vicinity of the pet absorbent sheet is hardly contaminated. The air-through nonwoven fabric wraps around the protruding portion of the air-through nonwoven fabric that protrudes even when the pet performs excrement etc. at the side end of the pet absorbent sheet. There is no leakage outside.

  FIG. 1 is a schematic perspective view for explaining a pet absorbent sheet according to a first embodiment of the present invention. FIG. 2 is a schematic view of a pet absorbent sheet according to the first embodiment of the present invention, and is a cross-sectional view taken along the line AA of FIG. 1 and 2, the pet absorbent sheet 11 of the present invention has a liquid-impermeable back sheet 12, a water absorbent member 13, and an air-through nonwoven fabric 14 laminated in order from the bottom. For example, tissue paper 131, paper fibers (pulp) 132, water-absorbing polymer 133, and tissue paper (color paper) 134 are laminated in order from the bottom. The tissue paper 131 can be conjugated with the side portions of the paper fibers (pulp) 132 and the water-absorbing polymer 133 as shown in FIG.

  The liquid-impermeable back sheet 12 is made of, for example, a polyethylene sheet, and is not particularly limited as long as excrement such as pet urine does not bleed out. The water absorbent member 13 in which the tissue paper 131, the paper fiber (pulp) 132, the water absorbent polymer 133, and the tissue paper (color paper) 134 are laminated in this order is made of a hydrophilic substance. It is possible to store excreta such as. The tissue paper (color paper) 134 is, for example, light blueish color paper. The air-through nonwoven fabric 14 is provided with protruding portions 141 and 142 that protrude larger than both end portions of the liquid-impermeable back sheet 12 and the water absorbent member 13 at both ends.

  The pet absorbent sheet 11 has a length of about 450 mm and a width of about 300 mm, for example. The water absorbing member 13 entering the inside of the pet absorbent sheet 11 has a length of about 400 mm and a width of about 260 mm. The air-through nonwoven fabric 14 is provided with protruding portions 141 and 142 that protrude in the width direction, preferably from 5 mm to 10 mm, or exceeding 10 mm. Further, the pet absorbent sheet 11 is formed with a seal portion 15 where the periphery of the side end portion excluding the protruding portion is bonded by, for example, hot melt or an adhesive. Each member of the pet absorbent sheet 11 is supplied in the length direction, bonded, and then cut to the length.

  Moreover, although the said absorbent sheet 11 for pets is produced vertically long, it can also be made horizontally long. For example, the pet absorbent sheet 11 has a length of about 430 mm and a width of about 650 mm, and, as described above, preferably 5 to 10 mm in the width direction, or a protruding portion 141 that protrudes beyond 10 mm, 142 is provided. The pet absorbent sheet 11 of the present invention can be arbitrarily selected in size, lengthwise or widthwise according to the pet.

  Since the air-through nonwoven fabric 14 is larger than both side end portions of the liquid-impermeable back sheet 12 and the water-absorbing member 13 and is provided with protruding portions 141 and 142 that protrude, a pet absorbent sheet. 11, even if the pet excretes urine or the like in the vicinity of the end portion, the excrement or the like is transmitted from the eating-out portions 141 and 142 to the back surface and absorbed by the water absorbing member 13. In addition, since most of the excrement and the like is absorbed by the water absorbing member 13, the vicinity of the pet absorbent sheet 11 is less likely to be stained.

  The present applicant compared the water retention amount of an equivalent product of the pet absorbent sheet of the present invention (having a protruding portion) and a conventional pet absorbent sheet (having no protruding portion). In an equivalent product of the pet absorbent sheet, 50 cc of physiological saline was dropped in the vicinity of the protruding portion of the air-through nonwoven fabric. The water retention after 5 minutes was 48.9 cc for the present invention and 37.6 cc for the conventional product.
