DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described below with reference to the drawings.
[0014]
FIG. 1 is a partial perspective view showing the pet sheet of the present invention with the back side (back sheet side) facing upward, and FIG. 2 is a cross-sectional view taken along the line II-II in FIG. Sectional drawing and FIG. 3 (A) (B) are explanatory drawings of the operation | movement which peels an adhesion layer from a mold release layer.
[0015]
In FIG. 1, the width direction of the pet sheet S is represented by the X direction, and the length direction is represented by the Y direction. The pet sheet S of the present invention includes a flat absorbent region Sc having an absorbent body 5, a flap Sa extending in the Y direction at both ends of the absorbent region Sc in the X direction, and rising substantially vertically from the sheet surface, and a flap. The extending sheet Sb extends further outward from the Sa in the X direction, and a thin boundary portion Sd at the boundary between the flap Sa and the absorption region Sc.
[0016]
As shown in FIG. 2, the pet sheet S has a rectangular top sheet 1, a back sheet 2 having the same size as the top sheet 1, and both sheets 1 and 2 having a size larger than these two sheets. It is a laminated structure in which a small absorbent body 5 is interposed.
[0017]
As the surface sheet 1, for example, a liquid-permeable nonwoven fabric made of synthetic fibers such as a point bond nonwoven fabric made of polypropylene (PP) fibers is used. Moreover, the surface sheet 1 may include a water absorbent fiber such as a rayon fiber, or a non-woven fabric formed only of the water absorbent fiber. The back sheet 2 is formed of a liquid-impermeable sheet such as a polyethylene (PE) film or a vinyl sheet, and the back sheet 2 is preferably a heat-fusible film such as the PE film.
[0018]
The absorbent body 5 has a slightly bulky flat shape in which the absorbent material 4 is sandwiched or wrapped by an absorbent sheet 3 such as a liquid-permeable and liquid-absorbing tissue. The absorbent material 4 is, for example, pulp or cotton containing a superabsorbent polymer (SAP) as necessary.
[0019]
In the absorption region Sc of the pet sheet S, an absorber 5 is sandwiched between the top sheet 1 and the back sheet 2. Further, a colored absorbent sheet 3 interposed between the absorbent material 4 and the top sheet 1 is used so that the front and back of the pet sheet S can be easily identified.
[0020]
In the peripheral part other than the absorption region Sc, the top sheet 1 and the back sheet 2 are heat-sealed and joined. Alternatively, the top sheet 1 and the back sheet 2 may be bonded with a hot melt adhesive or the like.
[0021]
As shown in FIG. 2, the flap Sa is folded in a mountain fold so that the back sheets 2 face each other at the joint where the top sheet 1 and the back sheet 2 are joined, and the back sheets 2 are joined. Has been formed. In this joining, the back sheets 2 of the heat-fusible film are joined by heat-sealing. Alternatively, the back sheets 2 may be bonded with a hot-melt adhesive or the like in a state where the joined body of both sheets 1 and 2 is folded.
[0022]
Since the flap Sa is a sheet in which the top sheet 1 and the back sheet 2 are joined and is further folded, and the back sheets 2 are joined to each other by heat fusion or the like, the flap Sa has the boundary Sd and the extension. The rigidity is higher than that of the exit sheet Sb. Due to the difference in rigidity, when the back sheet 2 of the absorption region Sc and the back sheet 2 of the extended sheet Sb are developed on the same plane, the flap Sa rises substantially vertically from the sheet surface.
[0023]
As shown in FIG. 2, the adhesive layer 6 is formed on the back surface of the extended sheet Sb. This adhesive layer 6 is a rubber-based elastomer or the like, and its adhesive force (tack force) is adjusted so as to have an appropriate adhesive force when the back sheet 2 of the pet sheet S is laid on the floor surface or the like. . If the adhesive strength is too strong, the coating on the floor surface may be peeled off or the resin layer on the floor surface may be peeled off when the pet sheet is peeled off from the floor surface. If the adhesive strength is too weak, the effect of preventing the pet sheet from shifting is reduced. Therefore, as the adhesive force (tack force) of the adhesive layer 6, the tack force obtained by the measurement method based on the “JIS Z 0237 probe tack force test” is about 230 gf / cm 2 or more and about 300 gf / cm 2 or less. More preferably, it is 250 gf / cm 2 or more and 280 gf / cm 2. Specifically, the tack force is a value obtained using a test apparatus called “tack force tester” manufactured by Pikuma. In this measurement, a square probe having a side length of 10 mm was first brought into contact with a square test piece (adhesive layer 6) having a side length of 25 mm for 1 second with a contact load of 500 g. Thereafter, the probe was peeled off from the test piece at a speed of 30 mm / min, the force when the probe was peeled off from the test piece was determined, and this force was taken as the value of the tack force of the probe. This tack force is expressed as a peeling force per area of the probe, and the unit is gf / cm 2 as described above. The tack force of the probe was measured on five test pieces. And the average value of the tack force measured with respect to each test piece is the said value.
[0024]
As shown in FIG. 1, the adhesive layer 6 is formed on the four corners of the back sheet, that is, on the back surfaces of the four corners of each extended sheet Sb.
[0025]
Further, release paper 7 is bonded and fixed as a release sheet to the inner side in the width direction of the portion where the adhesive layer 6 is formed, that is, to the four corners of the back surface of the absorption region Sc. The release paper 7 is obtained by applying a release agent such as a silicon-based resin to the surface of the base sheet, and the back side of the base sheet is bonded and fixed to the back sheet 2 of the pet sheet S.
[0026]
FIGS. 3A and 3B show the operation of attaching the adhesive layer 6 and the release paper 7.
[0027]
As shown to FIG. 3 (A), in the manufacturing process of the pet sheet S, the absorber 5 is installed on the back surface sheet 2, and the surface sheet 1 is installed on it. And the surface sheet 1 and the back surface sheet 2 are joined and heat-sealed in the side edge part of the area | region (absorption area | region Sc) in which the absorber 5 exists, and the junction part Se is formed. In addition, on the back surface of the absorption region Sc, a release paper 7 having an adhesive layer 6 formed on the front surface is bonded and fixed to the back sheet 2.
[0028]
Next, as illustrated in FIG. 3B, the joint Se where the top sheet 1 and the back sheet 2 are joined is folded in two. Then, the boundary portion Sd is left on the side of the absorption region Sc, the folded portion ahead of the boundary portion Sd is heated and pressurized, and the back sheets 2 are heat-sealed in the pressure region Sf, and the flap Sa Is formed.
[0029]
Further, as shown in FIG. 3B, the portion of the back sheet 2 that becomes the extended sheet Sb is adhered to the adhesive layer 6 in a state where the top sheet 1 and the back sheet 2 are folded.
[0030]
As shown in FIG. 3B, the pet sheet S is commercially available with the joint Se folded.
[0031]
When this pet sheet S is used, the extended sheet Sb is peeled off from the back surface of the absorbent region Sc, and the back surface of the extended sheet Sb and the back surface of the absorbent region Sc are flush with each other as shown in FIG. Expand to become. At this time, the highly rigid flap Sa heat-sealed rises from the sheet surface almost vertically.
[0032]
When the portion of the extended sheet Sb is peeled off from the back surface of the absorbent region Sc, the adhesive layer 6 is adhered to the back surface sheet 2 of the extended sheet Sb and peeled off from the release paper 7. In the unfolded state shown in FIG. 2, the pet sheet S is laid on the floor, tray, or bottom surface of the pet toilet, and the back surface of the extended sheet Sb is adhered to the floor or the like via the adhesive layer 6. When the extended sheet Sb is adhered to the floor or the like, not only the entire pet sheet S can be prevented from shifting, but also the back surface of the extended sheet Sb and the back surface of the absorption region Sc are maintained on the same surface, and thus the flap Sa Can stand upright without falling down.
[0033]
Further, in the folded state of FIG. 3B, the adhesive layer 6 is adhered to the release paper 7, so that the adhesive force is maintained. When the extended sheet Sb is peeled from the state of FIG. 3B, the adhesive layer 6 is adhered to the back sheet 2 side of the extended sheet Sb, and the adhesive layer 6 and the release paper 7 are easily peeled off.
[0034]
When the pet excretes urine in the absorption region Sc of the pet sheet S, the urine passes through the top sheet 1 and is absorbed by the absorber 5. Further, when the urine excretion position is the end of the absorption region Sc and the urine flows to the flap Sa, the urine is blocked by the flap Sa, the urine flows to the extension sheet Sb, and the floor surface or the like. Can be prevented from flowing out.
[0035]
FIG. 4 is a perspective view showing another embodiment of the pet sheet S of the present invention.
Similar to the pet sheet S shown in FIGS. 1 to 3, the pet sheet S is formed of a laminate in which an absorbent body 5 is interposed between the top sheet 1 and the back sheet 2.
[0036]
The adhesive layer 6 is formed on the back sheet 2 at the four corners of the pet sheet S. The pet sheet S is commercially available with both side portions in the Y direction folded inward so that the back sheet 2 faces each other at the fold lines Sg and Sg. In this folded state, the pet sheet S faces the adhesive layer 6. The release paper 7 is bonded and fixed to the surface of the back sheet 2 at the position where it is to be.
[0037]
When the pet sheet S is used, the entire pet sheet S is expanded in a flat state. At this time, when the adhesive layer 6 is peeled off from the release paper 7 and the pet sheet S is laid on the floor surface or the like, the adhesive layer 6 is adhered to the floor surface or the like to prevent the slippage. Since the release paper 7 is fixed to the back sheet 2, the release paper 7 does not become dust.
