DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a treatment mat of the present invention in which a pet excrement collection sheet of the present invention is set on an excrement absorbing mat. FIG. 2 is II-II in FIG.
It is sectional drawing of a line. Although the excrement collection sheet of the pet in FIG. 2 is exaggerated in the thickness direction, it is actually a thin sheet having a substantially uniform thickness.

In FIG. 1, an excrement collection sheet 10 formed of a rectangular water-disintegrable sheet of 20 cm × 15 cm has a size of 45 cm.
The treatment mat is formed by being adhered on the surface layer 2 substantially at the center of the rectangular excrement absorbing mat 1 of cm × 32 cm.

The shapes and sizes of the excrement collecting sheet 10 and the excrement absorbing mat 1 are appropriately adjusted, and may be square, circular, elliptical or the like. However, the excrement collection sheet 10 has a size of at least 14 cm × 14 cm, or 20 cm, so that the feces can be transported with the feces placed thereon.
It is preferable to have an area of 0 cm ² or more. More preferably, it is 15 cm × 20 cm or more.

When the pet excretes feces on the excrement collection sheet 10, the excrement collection sheet 10 is peeled off from the excrement absorption mat 1, and the excrement collection sheet 10 is transported to the toilet with the feces placed thereon. It can be flushed directly into the flush toilet. Then, since feces are not stained on the surface of the remaining excrement absorbing mat 1, it can be used as it is. Therefore, urine and the like excreted by the pet later can be absorbed, and the feet of the pet are not stained with feces.

As described above, the pet excrement disposal mat of the present invention can treat solid excrement such as feces by the excrement collection sheet 10 and liquid excrement such as urine by the excrement absorption mat 1. The waste can be treated without waste and in a hygienic manner.

The excrement collection sheet 10 of the present invention is such that when it is flushed into a flush toilet, the fibers are easily dispersed by the water flow or in the septic tank. For example, using pulp as a raw material, hydrolyzed paper formed into a sheet by hydrogen bonding between pulp fibers, water-disintegratable nonwoven fabric obtained by performing water jet treatment on a fiber web of water-dispersible fibers, and water-dispersible fibers A water-disintegrable sheet formed into a sheet by incorporating a water-soluble binder for binding fibers can be used.

Among these, a water-decomposable sheet formed by applying a binder to one surface of a fiber web composed of water-dispersible fibers is preferable. By applying the binder, the strength of the excrement collection sheet 10 can be increased. At this time, the surface on which the binder has been applied is the back surface 10b in contact with the surface layer 2 of the excrement absorbing mat 1.
Preferably, In this case, when the pet makes feces, the water contained in the feces does not easily penetrate into the excrement absorbing mat 1 laid under the excrement collection sheet 10.

Examples of the water-dispersible fiber include wood pulp (softwood pulp and hardwood pulp), pulp such as manila hemp, Linder pulp, bamboo pulp and kenaf, regenerated fiber such as rayon, and synthetic fiber such as polypropylene. Can be. The fiber length (average fiber length) is preferably 20 mm or less so that these fibers can be easily dispersed in water. Further, the fibers may be used in combination with different types of fibers such as pulp and rayon. In addition, the excrement collection sheet 10 may have a multilayer structure.

The binder is preferably a water-soluble binder, and examples thereof include polyvinyl alcohol, modified polyvinyl alcohol, starch, alkylcellulose such as carboxymethylcellulose and methylcellulose, and cationic aldehyde-modified polyacrylamide copolymer. In addition, when a polyvinyl alcohol-based water-soluble binder or a cellulose-based water-soluble binder is used, an electrolyte or a metal salt can be contained as necessary to increase the strength of the hydrolyzed paper. When an alkylcellulose-based water-soluble binder is used, a copolymer of an acrylic acid resin or an amino acid derivative can be contained in order to increase the strength of the hydrolyzed paper.

The excrement collection sheet 10 of the present invention preferably has such a rigidity that the feces can be carried thereon. Therefore, the excrement collection sheet is JIS / L
The stiffness measured by the cantilever method of 1096 is 30 mm /
It is preferably 25 mm or more. A more preferred bending resistance is 80 mm / 25 mm or more. In addition, if the rigidity is high, there is also an advantage that the sheet does not roll up or twist or warp before or during excretion of the pet. In addition, in order to prevent feces from rolling out from the excrement collection sheet 10 to the surroundings,
The excrement collection sheet 10 may be creped to increase the surface friction coefficient.

The excrement collecting sheet 10 can be hooked on the surface layer 2 of the excrement absorbing mat 1 during use, and can be peeled off from the excrement absorbing mat 1 after excretion (after use). Is provided with a peelable adhesive 11.
The adhesive strength of the adhesive 11 is 200 g / g so that the excrement collecting sheet 10 can be easily peeled off the excrement absorbing mat 1.
It is preferably 25 mm or less. As the adhesive 11, a water-soluble adhesive is preferable, and examples thereof include carboxymethylcellulose, polyvinyl alcohol, sodium alginate, and starch. However, a water-insoluble adhesive or a hot-melt adhesive may be used.
If the excrement collection sheet 10 contains heat-fusible fibers, the excrement collection sheet 10 may be adhered by heat heat sealing or impulse sealing. Note that the adhesive 11 is the excrement collection sheet 1
Instead of being provided on the 0 side, it may be provided on the excrement absorbing mat 1 to which the excrement collecting sheet 10 is adhered.

The excrement collecting sheet 10 of the present invention can be colored blue or the like to give a clean impression to a person. Further, a pattern may be printed on the surface of the excrement collection sheet 10.

On the other hand, the excrement absorbing mat 1 is generally used. For example, as shown in FIGS. 1 and 2, the absorbent core 4 is made of a liquid-impermeable backing layer 3 and a liquid-permeable backing layer. It is sandwiched between the surface layer 2. The absorbent core 4 is provided with a superabsorbent resin on both the surface and the bottom of the pulp layer 6. That is, the superabsorbent resin 5 is formed on the surface of the pulp layer 6.
a, the superabsorbent resin 5b exists on the bottom surface of the pulp layer 6. The surface layer 2 and the back layer 3 are joined at the end 8 of the excrement absorbing mat 1.

The superabsorbent resins 5a and 5b are, for example, polymers represented by polyacrylic acid, polyvinyl alcohol, maleic anhydride and other addition polymers, polyethers, condensation polymers, starches, celluloses and the like. Granules made of proteins such as polysaccharides and collagen can be used. Examples of the superabsorbent resin include a crosslinking compound of sodium polyacrylate, a starch copolymer of sodium polyacrylate, and a cellulose copolymer of polyacrylonitrile. Among them, sodium polyacrylate or a cross-linking compound of polyacrylic acid is preferable because it is inexpensive. In addition, the absorbent core 4 is not provided with the superabsorbent resin 5a, 5b, and may be formed only of pulp, or may be composed of pulp and the superabsorbent resin dispersed in the pulp.

The liquid-permeable surface layer 2 is, for example, a point-bonded nonwoven fabric. The point bond nonwoven fabric is formed from a synthetic fiber such as a polyethylene fiber, a polypropylene fiber, or a composite fiber thereof. Further, the point bond nonwoven fabric may contain water-absorbing fibers such as rayon fibers. On the other hand, the liquid-impermeable back layer 3 is a polyethylene (PE) film, a vinyl sheet, or the like.

As shown in FIG. 1, the surface of the absorbent core 4 is preferably covered with absorbent paper, for example, tissues 7a and 7b. The absorber 4 covered with tissue is easy to handle in the manufacturing stage. In addition, the presence of the tissue 7b causes the relatively hard superabsorbent resin 5b to be
Hard to hurt. The tissue 7a under the surface layer 2 of the pet excrement absorbing mat 1 is preferably colored in blue or the like to give a clean feeling.

In the treatment mat of the present invention described above, the excrement collecting sheet 10 is bonded to the excrement absorbing mat 1 in advance. However, only the excrement collection sheet 10 is sold,
The user (owner) may adhere the purchased excrement collection sheet to the separately purchased excrement absorbing mat 1 at the time of use. In this case, if the adhesive is water-soluble, the user can apply a small amount of water to the adhesive to express the adhesiveness, and can easily adhere to the excrement absorbing mat 1. There is no dust like release paper covering the adhesive until it is used for holding.

In addition, the excrement collection sheet 10 of the present invention is not limited to being used by being placed on the excrement absorption mat 1, but is laid on a material such as a newspaper which performs the same function as the excrement absorption mat 1. May be used.

[0029]

As described in detail above, the excrement collection sheet of the present invention is such that the pet removes the excrement from the excrement absorption mat after the pet makes the excrement on the excrement collection sheet, and puts the excrement of the pet on the excrement collection mat. Since it can be transported in a state of being put on or wrapped in it and thrown away in a toilet, disposal of feces is simple and sanitary. In addition, since the excrement absorbing mat can be continuously used in a sanitary state without being stained by feces, the excrement absorbing mat can be used without waste.
