An absorbent body 4 made of cotton-like pulp or synthetic pulp interposed between the two sheets 2 and 3 and a deodorizing sheet 5 surrounding the absorbent body in order to maintain the shape of the absorbent body 4 and improve diffusibility. And a hydrophilic second sheet 6 disposed between the liquid-permeable surface sheet 3 and the absorbent body 4 as necessary, and a substantially side edge of the absorbent body 4 as an upright base end, and at least urine The absorbent body is mainly composed of a pair of left and right three-dimensional gathers BS, 7 formed on the skin side in a predetermined section in the longitudinal direction so as to include the discharge site H, and side nonwoven fabrics 7 and 7 forming the BS. In the vicinity of 4, its length The outer edge portion of the liquid-impervious back sheet 2 and the liquid-permeable surface sheet 3 is joined at an edge portion in the direction by an adhesive such as hot melt or an adhesive means such as heat seal. The liquid-impervious back sheet 2 and the side nonwoven fabric 7 extending to the side of 4 are joined by an adhesive such as hot melt or an adhesive means such as heat seal.

Hereinafter, the structure of the incontinence pad 1 will be described in detail.
The liquid-impervious back sheet 2 is made of a sheet material having at least water-impervious properties such as polyethylene and polypropylene, but in addition to this, a non-woven sheet after securing a substantially liquid-impervious property through a waterproof film. (In this case, a liquid-impervious back sheet is composed of the waterproof film and the nonwoven fabric). In recent years, those having moisture permeability tend to be suitably used from the viewpoint of preventing stuffiness. The water- and moisture-permeable sheet material is a microporous material obtained by melting and kneading an inorganic filler in an olefin-based resin such as polyethylene or polypropylene to form a sheet, and then stretching in a uniaxial or biaxial direction. A sheet is preferably used.

  Next, as the liquid-permeable surface sheet 3, a porous or non-porous nonwoven fabric or a porous plastic sheet is preferably used. Examples of the material fibers constituting the nonwoven fabric include synthetic fibers such as polyethylene or polypropylene, synthetic fibers such as polyester and polyamide, recycled fibers such as rayon and cupra, and natural fibers such as cotton. A nonwoven fabric obtained by an appropriate processing method such as a lace method, a spun bond method, a thermal bond method, a melt blown method, or a needle punch method can be used. Among these processing methods, the spunlace method is excellent in terms of flexibility and drapeability, and the thermal bond method is excellent in terms of being bulky and soft.

  The absorbent body 4 is composed of, for example, absorbent fibers such as fluffy pulp and the superabsorbent polymer 8, and in the illustrated example, the planar shape is an oblong shape that is long in the longitudinal direction of the pad. The superabsorbent polymer 8 is, for example, granular powder, and is dispersed and mixed in the pulp constituting the absorber 4.

In the case of hydrophobic fibers, it is desirable to use the synthetic fibers surface-treated with a hydrophilizing agent so as to have affinity for urine.

  The deodorizing sheet 5 is a three-layered sheet formed by laminating pulp sheets (paper materials such as tissues) 15 and 16 on the upper and lower surfaces of the deodorizing layer 17 containing a deodorant. The deodorizing layer 17 is mainly composed of a porous deodorant such as activated carbon particles, porous polymer, silica gel, zeolite or the like, or a porous deodorant and a fiber raw material. As said fiber raw material, natural fibers, such as cotton other than a wood pulp, can be used, for example. The pulp sheets 15 and 16 may be white, but may be colored to make the color of urine inconspicuous. Further, a nonwoven fabric can be used in place of the pulp sheets 15 and 16. In addition, other known deodorant components can be used.

  The second sheet 6 only needs to be hydrophilic to urine. Specifically, by using recycled fibers such as rayon and cupra, natural fibers such as cotton, the material itself has hydrophilicity, or synthesis of olefins such as polyethylene or polypropylene, polyesters, polyamides, etc. The fiber which surface-treated with the hydrophilizing agent and provided the hydrophilic property can be used. Further, the second sheet 6 may have a porous film layer on the back surface side (absorber 4 side) in order to give a firmness, and a material containing pulp may be used.

  The overlapping portion 23 may be provided at any position in the pad width direction as long as it is provided on the skin contact surface side of the absorbent body 4, but as shown in FIG. It is preferable to provide it at the center position in the direction. Thereby, the deodorizing sheet 5 extended from each absorber side edge will be arrange | positioned at the both sides of the absorber recessed part 20, and when providing the said embossing part 21, the deodorizing sheet 5, 5 in the said overlap part 23 Sliding between each other is likely to occur, and the embossing of the left and right deodorizing sheets 5 with the embossed portion 21 as a boundary can be prevented. As shown in FIG. 11, the overlapping portion 23 may be provided at a position where it does not overlap the absorber recess 20, that is, at a position displaced in the width direction with respect to the absorber recess 20.

  As shown in FIG. 12, the width S of the overlapping portion 23 is in the range of S ≧ (A + B / 2), where A is the depth of the absorber recess 20 and B is the width of the bottom surface of the absorber recess 20. Can be provided. When provided in the range of S ≧ (A + B / 2), as shown in FIG. 12 (B), when the embossed portion 21 is provided, the entire inner surface of the absorber recess 20 is covered with the deodorizing sheet 5. Therefore, polymer spillage can be prevented. On the other hand, if the width S of the overlapping portion 23 is too large, the deodorizing sheets 5 and 5 are not easily slipped at the overlapping portion 23 when the embossed portion 21 is formed, and the deodorizing sheet 5 is easily pulled, so embossing is imparted. When it does, it is preferable to provide in the range which the edge part of the deodorizing sheet 5 is located in the bottom face of the absorber recessed part 20. FIG. In the state after embossing, the overlap margin K of the deodorizing sheets 5 and 5 is desirably about 3 to 8 mm.

  As shown in FIG. 9, the absorber 4 surrounded by the deodorizing sheet 5 is embossed along the absorber recess 20 inside the absorber recess 20 by embossing from the skin contact surface side. A portion 21 is formed.

  The embossed portion 21 may be provided by squeezing at least from the skin contact surface side of the deodorant sheet 5, or the liquid-permeable surface sheet 3 and, if necessary, the skin contact surface side of the deodorant sheet 5. In a state where the second sheet 6 is laminated, the liquid-permeable surface sheet 3, the second sheet 6 and the deodorizing sheet 5 are integrally provided by pressing from the skin contact surface side of the liquid-permeable surface sheet 3. May be. Moreover, after providing the embossing by pressing from the skin contact surface side of the deodorant sheet 5 in the state where the absorber 4 is surrounded by the deodorant sheet 5, the liquid-permeable surface sheet 3 and necessary on the skin contact surface side Then, in a state where the second sheet 6 is laminated, a two-stage embossing is applied to the liquid-permeable surface sheet 3 and the second sheet 6 by embossing from the skin contact surface side of the liquid-permeable surface sheet 3. Also good. In any case, at least the compression of the absorbent body 4 due to the tension of the deodorant sheet 5 can be prevented.

  The planar dimension of the embossed portion 21 may be the same as or smaller than the dimension of the absorber recess 20. On the bottom surface of the embossed portion 21, a high-pressure squeezed portion squeezed deeper than the bottom surface of the peripheral concave groove 22 may be formed in an appropriate pattern.

  The deodorizing sheet 5 is provided with a non-joining region 24 that does not join the deodorizing sheets 5 and 5 of the overlapping portion 23 in at least a longitudinal range corresponding to the embossed portion 21 of the overlapping portion 23. The non-bonding region 24 is a case where the deodorizing sheets 5 and 5 are simply laminated, such as bonding the deodorizing sheets 5 and 5 of the overlapping portion 23 by a bonding means such as hot melt adhesive or heat seal. It is an area where no means is applied to prevent slipping between the deodorant sheets 5 and 5. Further, the longitudinal range corresponding to the embossed portion 21 is a range that overlaps the provision planned region 21 ′ of the embossed portion 21 in the pad width direction.

  The non-bonding region 24 can be provided over the entire length of the overlapping portion 23. Thereby, when providing the said embossed part 21, while the tension | tensile_strength of the deodorizing sheet 5 comes to be suppressed more reliably, a manufacturing process can be simplified.

  Further, as shown in FIG. 8, the non-bonded region 24 is provided only in the pad longitudinal direction intermediate portion including the embossed portion 21, and the deodorizing sheet 5 of the overlapping portion 23 is formed at both ends in the longitudinal direction. Bonding regions 25 and 25 can be provided in which five members are bonded by a known bonding means such as a hot melt adhesive or heat seal. By providing the joining regions 25, 25, it is possible to prevent the material from fluttering during the line conveyance in the manufacturing process and causing the deodorized sheet 5 to be turned over and the polymer spilled out. When a hot melt adhesive is used as the joining means, it is preferably applied by a method such as spiral or bead that does not inhibit urine penetration. The joining region 25 may be provided continuously outside the non-joining region 24 or may be provided intermittently with a non-joining region interposed therebetween. The joining region 25 may be configured by temporarily joining by spraying water spray or the like instead of joining by the joining means such as the hot melt adhesive or heat seal described above.

  In the example shown in FIG. 8, the embossed portion 21 (21 ′) is formed in a range shorter in the longitudinal direction of the pad than both end portions in the groove direction of the absorber concave portion 20, and the longitudinal end portion of the non-bonded region 24 is embossed. The bonding regions 25, 25 are provided at both ends of the pad longitudinal direction outside the non-bonding region 24, respectively, so as to be located in the middle of the longitudinal range of the portion 21 and the longitudinal edge of the absorber recess 20. Is provided. In other words, the end portion of the non-bonded region 24 is located between the end portion of the absorber recess 20 and the end portion of the embossed portion 21. Thereby, the surface side of the absorbent body 4 where the absorbent body concave portion 20 is not provided is covered with the deodorizing sheet 5, and polymer spillage can be reliably prevented, and the deodorizing sheet 5 is reliably pulled when the embossed portion 21 is formed. Can be prevented.

  According to the incontinence pad 1 having the above configuration, the non-bonding region 24 is provided in the overlapping portion 23 of the deodorizing sheet 5 so that the deodorizing sheets 5 and 5 stacked in the non-bonding region 24 are not bonded. Therefore, slipping occurs between the deodorizing sheets 5 and 5 during compression when the embossed portion 21 is provided, and deformation of the deodorizing sheet 5 due to the pressing is absorbed, so that the deodorizing sheet 5 is suppressed from being pulled by the embossing. The Therefore, the deodorizing sheet 5 can be prevented from being torn, and the absorber 4 around the embossed portion 21 can be reduced by being compressed by the deodorized sheet 5 and the volume of the embossed portion 21 can be reduced. Can be prevented.

  Further, the absorbent body 4 is provided with an absorbent body recess 20 in advance without being squeezed, and the embossed portion 21 is embossed from the skin contact surface side along the absorbent body recess 20 inside the absorbent body recess 20. Therefore, even when urine permeates into the absorbent recess 20 and the pulp or polymer around the absorbent recess 20 expands, the swelling at the time of expansion is suppressed to be extremely small as compared with the case where the recess is formed by pressing. Therefore, it is possible to prevent the absorbent recess 20 from being blocked and the urine absorption performance from being lowered.

  Next, the manufacturing procedure until the embossed portion 21 of the incontinence pad 1 is formed will be described. After the absorbent body 4 having the embossed concave portion 20 is manufactured in advance by stacking or a laminated structure, the absorbent body 4 is It is placed on the deodorizing sheet 5, surrounds the absorbent body 4 in a predetermined folding manner, and, if necessary, joins the joining region 25 with a predetermined joining means, thereby bringing the skin of the absorbent body 4 into contact with the skin. The embossed portion 21 is formed by embossing from the skin contact surface side with the overlapping portion 23 provided on the surface side.

  When providing the embossed portion 21, as described above, embossing may be applied integrally from the skin contact surface side of the liquid-permeable surface sheet 3, or from the skin contact surface side of the deodorizing sheet 5. Then, it is good also as a two-step embossing provided from the skin contact surface side of the liquid-permeable surface sheet 3 further.

When the joining region 25 is provided in the overlapping portion 23, water spray is sprayed on a region other than the longitudinal range corresponding to the embossed portion 21 (the joining region 25 shown in FIG. 8), and the deodorizing of the overlapping portion 23 is performed. The sheets 5 and 5 can be temporarily joined together. Since the portion where the water spray is sprayed becomes easy to temporarily stick to the deodorizing sheets 5 and 5 due to the viscosity and surface tension of the water, the turning of the deodorizing sheet 5 due to flapping during line transportation in the manufacturing process is prevented. it can. Further, by applying the water spray, it is not necessary to provide the joining region 25, and the manufacturing process can be simplified. The moisture generated by the water spray naturally evaporates during the subsequent manufacturing process and product transportation, and therefore does not affect the product characteristics.
