[Formation for carrying out the invention]

Referring to Fig. 1, the disposable disposable diaper 1 of the disposable wearing article of the present invention has a longitudinal direction Y and a lateral direction X, and includes: a skin facing surface and a non-skin on the opposite side of the skin. The opposing face, the front waist region 12 and the back waist region 13, the crotch region 14 between the front and rear waist regions 12, 13, and the elastic front and rear waist regions 20, 30 of the front and rear waist regions 12, 13 are used for zoning The partial region 14 is attached to the crotch sheet 40 on the skin facing surface side of the front and rear waist sheets 20 and 30, And an absorber 50 disposed on the inner side of the crotch sheet 40 and extending in the longitudinal direction Y.

The front and rear waist sheets 20, 30 are divided by inner end edges 20A, 30A, outer end edges 20B, 30B, and side edges 20C, 30C, respectively. The side edges 20C and 30C overlap each other, and the seam portion 15 which is intermittently arranged in the longitudinal direction Y is joined by a well-known means such as thermal embossing/sinking processing, sonic processing, and the like. An annular elastic waist sheet is formed, and a pair of leg openings 17 are defined together with the waist opening 16.

Referring to Figures 2 to 4, the disposable diaper 1 has a virtual longitudinal centerline 2-2 which bisects the dimension of the lateral direction X, and a virtual transverse centerline 3-3 which bisects the dimension of the longitudinal direction Y, It is roughly symmetrical to the virtual longitudinal centerline 2-2. The front and rear waist sheets 20 and 30 respectively have inner sheet sheets 21 and 31 on the skin facing surface side and outer sheet sheets 22 and 32 on the non-skin facing surface side. The width dimension of the longitudinal direction Y of the outer layer sheets 22, 32 is larger than the width dimension of the longitudinal direction Y of the inner layer sheets 21, 31 and extends from the inner and outer end edges of the inner layer sheets 21, 31 toward the outer side of the longitudinal direction Y, respectively. The inner sheets 21, 31 and the outer sheets 22, 32 are adhered by a hot-melt adhesive coated on at least one of the inner faces or a well-known heat-welding means.

For the outer sheet 22, 32, an SMS (spunbond, meltblown, spunbond) fiber nonwoven fabric, a spunbonded nonwoven fabric, a breathable fiber nonwoven fabric, a plastic sheet, or any of the foregoing may be used having a mass of about 10 to 30 g/m ² . A laminated sheet of fiber non-woven fabric and plastic sheet.

As the inner layer sheets 21, 31, an elastic fiber nonwoven fabric can be used. For example, a spunbonded nonwoven fabric, a meltblown fiber nonwoven fabric, a hot rolled fiber nonwoven fabric, an SMS fiber nonwoven fabric, an air jet formed fiber nonwoven fabric, and a gas permeable nonwoven fabric can be used alone or in combination. A fiber nonwoven fabric which is known to be elastic is formed. The elastic nonwoven fabric can be formed, for example, of an elastomer resin composed of a polyethylene-based or polyurethane-based resin, a thermoplastic resin such as polyethylene, polypropylene, polyester, or acrylic. As the inner layer sheets 21, 31, a non-elastic fiber nonwoven fabric can also be used.

The outer sheet 22, 32 further includes: bending portions 22A, 32A extending from the outer edge portions of the inner layer sheets 21, 31 toward the outer side of the longitudinal direction Y and being folded back toward the longitudinal direction Y; and the inner sheet 21, The inner edge portion 31 extends toward the virtual transverse center line 3-3 and extends out of the portions 22B and 32B. In the bent portions 22A and 32A, a plurality of strands or elongated first and second elastic bodies 24 and 34 are retractably fixed by elongation through a hot-melt adhesive. The first and second elastic bodies 24 and 34 extend substantially in the entire region in the lateral X direction. By arranging the first and second elastic bodies 24 and 34, in particular, the waist opening 16 of the disposable diaper 1 can be closely attached to the wearer, and leakage of excrement such as urine from the waist can be prevented.

The elongated fixing sheets 25 and 35 formed of the fiber nonwoven fabric are disposed on the extending portions 22B and 32B, and are disposed between the fixing sheets 25 and 35 and the extending portions 22B and 32B via the hot-melt adhesive. The third and fourth elastic bodies 26, 36 in the form of strands or strips are retractably fixed under elongation. The third and fourth elastic bodies 26 and 36 form a discontinuous ‧ inelastic region in the vicinity of the virtual longitudinal center line 2-2. Forming the inelastic domain For example, in the central portion of the outer sheets 22, 32, no adhesive is applied, and only the adhesive is applied to both sides thereof, and the region coated with the adhesive and the uncoated region are provided in a continuous state in an extended state. The third and fourth elastic bodies 26 and 36 are fixed to the application region of the adhesive, and in this state, the third and fourth elastic bodies 26 and 36 located in the non-coated region of the adhesive are cut and borrowed. Thereby, the inner end portions in the longitudinal direction of the third and fourth elastic bodies 26 and 36 can be contracted (rebounded) to form an inelastic region. Further, for example, the inelastic domains may be formed by placing the third and fourth elastic bodies 26 and 36 located in the non-elastic region in an unstretched state. Further, for example, the inelastic domain may be formed by losing or suppressing the contractility of the third and fourth elastic bodies 26, 36 which are elongated in the inelastic region. By forming the non-elastic domain, it is possible to prevent the absorbent body 50 disposed on the virtual longitudinal center line 2-2 from being wrinkled, and the leg openings 17 are dense by the contraction force of the third and fourth elastic bodies 26, 36. Stick to the wearer to prevent leakage of urine and the like.

For the first to fourth elastic bodies, for example, an elastic yarn having a thickness of about 310 to 940 dtex and an elongation ratio of 2.0 to 3.5 times can be used.

The front and rear waist sheets 20 and 30 have inner regions 61 and 62 in which the third and fourth elastic bodies 26 and 36 are disposed, and outer regions 63 and 64 in which the first and second elastic bodies 24 and 34 are disposed, and Located in the intermediate regions 65, 66 between the above regions. The longitudinal Y dimension of the inner regions 61, 62 is about 10 to 40% of the longitudinal Y dimension of the front and rear waist panels 20, 30, and in the present embodiment, about 27.3% (about 30 mm).

Between the inner sheets 21, 31 and the outer sheets 22, 32, the central portion of the lateral X region of the front and rear waist regions 12, 13 is formed of a plastic material. The graphic display films 23, 33. On the non-skin contrast surface of the graphic display films 23 and 33, a pattern (not shown) that can be recognized from the outside is printed.

The crotch sheet 40 has a rear end edge portion 40A, 40B extending toward the lateral direction X and overlapping the front and rear waist sheets 20, 30, and both side edges 40C extending toward the longitudinal direction Y, and front and rear edge portions 40A, 40B The inner regions 61 and 62 of the front and rear waist sheets 20 and 30 are overlapped and joined, respectively. Therefore, the crotch sheet 40 overlaps in the range of about 10 to 40% of the longitudinal Y dimension of the front and rear waist sheets 20, 30.

The crotch sheet 40 has a base sheet 41 located at a central portion of the lateral direction X and a pair of leg elasticized sheets 42 fixed to both side portions of the base sheet 41. The front and rear end edges 40A and 40B are formed by the front end edge portion of the base sheet 41 and the leg elasticizing sheet 42, and the both side edge portions 40C are formed by the outer side edge portion 42C of the leg elasticizing sheet 42.

The base sheet 41 is composed of an inner sheet 43 located on the opposite side of the skin and an outer sheet 44 on the non-skin facing side. As the inner and outer sheets 43, 44, various well-known fiber nonwoven fabrics or plastic films can be used. However, the inner sheet 43 is preferably formed of a leak-proof plastic film, and the outer sheet 44 is formed as a disposable diaper 10 A part of the outer portion is preferably formed of a fiber non-woven fabric having a better touch than a plastic film. The leg elasticized sheet 42 has an inner edge portion fixed between the inner and outer sheets 43, 44.

The leg elasticized sheet 42 has a bent portion 45 which is folded back in the lateral direction X at the outer edge portion 42C, and a plurality of strands extending in the longitudinal direction Y are fixed inside the sleeve formed by the bent portion 45 or Long strip elasticity Body 46. As the elastic body 46, an elastic yarn having a thickness of about 310 to 620 dtex and an elongation ratio of about 2.0 to 3.0 times can be used, and it can be fixed by shrinkage under elongation by a hot melt adhesive. The elastic body 46 has: an inner elastic body 46A closest to the virtual longitudinal center line 2-2, that is, an inner side elastic body 46A located on the inner side of the lateral direction X; an outer side outer elastic body 46B located at the outermost side of the lateral direction X; and an intermediate elastic body 46C located between the outer sides . In the present embodiment, one of the inner elastic body 46A and the outer elastic body 46B is used, and the intermediate elastic body 46C uses four elastic yarns. The outer elastic body 46B is located on the outer side edge portion 42C of the leg elasticized sheet 42, and the bent portion 45 is bent along the outer elastic body 46B.

The tensile stress of the inner elastic body 46A is greater than that of the outer elastic body 46B and the intermediate elastic body 46C. For example, the inner elastic body 46A is an elastic yarn having a thickness of about 470 dtex and an elongation ratio of about 2.45, and the outer elastic body 46B and the intermediate elastic body 46C are elastic yarns having a thickness of about 310 dtex and an elongation ratio of about 2.45.

Since the tensile stress of the inner elastic body 46A of the leg elasticized sheet 42 is greater than that of the outer elastic body 46B and the intermediate elastic body 46C, the crotch sheet 40 can be closely attached to the wearer at a position closer to the absorbent body 50, and can prevent excretion. The leakage of things. Further, since the tensile stress of the outer elastic body 46B and the intermediate elastic body 46C is relatively small, the leg elasticized sheet 42 can be prevented from sliding into the inner side and the leg elasticized sheet 42 can be closely attached to the leg root of the wearer.

The third elastic body 26 extending in the lateral direction X intersects with the entire inner elastic body 46A, the outer elastic body 46B, and the intermediate elastic body 46C of the front waist sheet 20 . Therefore, by the contraction force of the third elastic body 26, suction The body 50 is closely attached to the wearer's body, and the movement of the wearer's thigh does not form a gap between the body and the absorbent body 50 that induces leakage of body fluid. In the back waist sheet 30, the fourth elastic body 36 extending in the lateral direction X intersects with one of the outer elastic body 46B and the intermediate elastic body 46C, and does not intersect with the remaining intermediate elastic body 46C and the inner elastic body 46A. Therefore, in the rear waist region 13, there is no possibility that the contraction force acts on the absorber 50 to cause cracks or wrinkles due to leakage of body fluid.

Here, the "intersection" between the elastic body 46 and the third and fourth elastic bodies 26, 36 in the present invention means a fixed sheet in which the third and fourth elastic bodies 26, 36 are fixed in a telescopic state. 25, 35, and the mutual engagement of the leg elasticized sheets 42 of the elastic body 46 in a telescopic state, so that the effective elongated portion of the elastic body 46 and the effective elongated portions of the third and fourth elastic bodies 26, 36 can be Produce a state of substantial linkage.

The liquid absorbing absorbent body 50 is disposed on the skin facing surface of the base sheet 41 of the crotch sheet 40. The absorbent body 50 is a vertically long gasket shape and includes: front and rear end edge portions 50A, 50B, both side edge portions 50C, an absorbent core 51 extending toward the longitudinal direction Y in the crotch portion region 14, and being located in the absorbent core 51. The body side liner 52 of the absorbent surface. The front end edge portion 50A is fixed to the inner layer sheet 21 of the front waist sheet 20 via a hot melt adhesive. The rear end edge portion 50B is fixed between the inner layer sheet 31 and the outer layer sheet 32 of the rear gusset sheet 30 via a hot-melt adhesive, and more specifically, is fixed to the inner layer sheet 31 and the fixed sheet sheet 35. between. The intermediate portion of the front and rear end edges 50A, 50B is fixed to the inner surface of the crotch sheet 40 via a hot-melt adhesive. Sheet 43. The vicinity of the front edge portion 50A of the absorbent body 50 is fixed to the skin facing surface of the inner layer sheet 21, so that the relatively soft inner layer sheet 21 having elasticity and elasticity directly contacts the wearer's skin, thereby improving the tactile sensation. Further, since the vicinity of the rear end edge portion 50B is fixed between the inner layer sheet 31 and the outer layer sheet 32, even if the excreted body fluid is diffused from the crotch region 14 to the absorber 50 located in the rear waist region 13, the body fluid can be prevented directly. Touch the skin of the wearer.

The absorbent core 51 is of a mass of about 200 to 800 g/m ² and is composed of a mixture of fluff pulp, superabsorbent polymer particles (SAP), and a heat-fusible stabilizing fiber as an option. The core material; and the liquid-permeable fiber non-woven fabric covering the core material. As the body side liner 52, various well-known fiber nonwoven fabrics such as a liquid-permeable spunbond nonwoven fabric having a mass of about 10 to 30 g/m ² and an SMS nonwoven fabric can be used.

In particular, referring to Fig. 2, the longitudinal Y dimension L1 of the crotch sheet 40 is smaller than the dimension L2 of the absorbent body 50, and the front end edge portions 50A, 50B of the absorbent body 50 are before the rear end edge of the crotch sheet 40. The portions 40A, 40B are closer to the outer side of the longitudinal direction Y. Since the longitudinal Y dimension of the crotch sheet 40 is small, the area of the crotch sheet 40 superimposed on the front and rear waist sheets 20 and 30 is reduced, and the air permeability of the front and rear waist sheets 20 and 30 can be ensured. In the present embodiment, the longitudinal dimension L1 of the crotch sheet 40 is about 296 mm, and the dimension L2 of the absorbent body 50 is about 330 mm.

The lateral X dimension W1 of the crotch sheet 40 is larger than the dimension W2 of the absorber 50, and both side edges 40C of the crotch sheet 40 extend outward in the lateral direction X from the both side edges 50C of the absorber 50. Absorber 50 facing horizontal The outer side of the X extension is the leg elasticized sheet 42 of the crotch sheet 40, which can be softly adhered to the wearer. In the present embodiment, the lateral dimension W1 of the crotch sheet 40 is about 210 mm, and the dimension W2 of the absorbent body 50 is about 115 mm.

In the absorbent body 50, the size of the body side liner 52 is larger than the longitudinal Y dimension of the absorbent core 51, and the front side edge portions 52A, 52B of the body side liner 52 are directed toward the longitudinal direction Y of the front end edge portions 51A, 51B of the absorbent core 51. The outside extends out. The front side edge portions 52A, 52B of the body side liner are aligned with the front end edge portions 50A, 50B of the absorbent body 50. The front edge portion 51A of the absorbent core 51 is located in the intermediate portion 65 of the front waist sheet 20. In other words, the front end edge portion 51A is located closer to the outer side of the longitudinal direction Y than the front end edge portion 40A of the crotch portion sheet 40. When the disposable diaper 1 is worn, since the urination organ is closer to the front waist region 12 side than the virtual transverse center line 3-3, the absorption of the urine can be performed with good efficiency by preventing the absorbent core 51 from being displaced toward the front side, and urine is prevented. Leaked out of the disposable diaper 1. The rear edge portion 51B of the absorbent core 51 is located in the inner region 62 of the back waist sheet 30. In other words, the rear end edge portion 51B is located closer to the inner side of the longitudinal direction Y than the rear end edge portion 40B of the crotch portion sheet 40. Therefore, the rear end edge portion 51B can be adhered to the wearer's skin by the fourth elastic body 36 and the elastic body 46, and in particular, leakage of feces such as stools from the rear waist region 13 can be prevented.

In the front and rear waist sheets 20, 30, the crotch sheet 40 overlaps only the inner regions 61, 62 and does not overlap the intermediate regions 65, 66 and the outer regions 63, 64. Therefore, when the disposable diaper 1 is worn, the wearer's foot is less likely to be caught by the crotch sheet 40. Assume that the crotch sheet 40 extends to When the intermediate regions 65, 66 or the outer regions 63, 64 are up, the fingers of the wearer easily hook the front and rear end edges 40A, 40B or the side edge portions 40C, which may cause difficulty in wearing.

Further, by joining the crotch sheet 40 to the inner regions 61 and 62, the front and rear end portions 40A and 40B can be closely attached to the wearer's body by the contraction force of the third and fourth elastic members 26 and 36. . Therefore, it is possible to suppress the situation in which the front and rear end edges 40A, 40B float upward to stimulate the wearer's skin.

Referring to Fig. 5, the inner region 61 of the front waist sheet 20 has the leg elasticized sheet 42 of the crotch sheet 40 on the outer side of the both side edges 50C of the absorbent body 50. Referring to Fig. 6, when the disposable diaper 1 is worn, the leg elasticized sheet 42 is adhered to the body H of the wearer by the contraction force of the elastic body 46. Therefore, on the outer side of the lateral direction X of the both side edges 50C of the absorbent body 50, the skin H of the wearer and the skin facing surface of the disposable diaper 1 hardly form or form only a small gap 53.

Referring to Fig. 7, in the intermediate portion 65 of the front waist sheet 20, since the crotch sheet 40 does not overlap, there is no leg elasticized sheet 42 outside the lateral X of the both side edges 50C of the absorbent body 50. . Referring to Fig. 8, when the disposable diaper 1 is worn, the intermediate portion 65 of the front waist sheet 20 is on the outer side of the lateral X of the both side edges 50C of the absorbent body 50, and the skin H of the wearer and the skin of the disposable diaper 1 Between the gaps 53 larger than the inner region 61 of Fig. 6 is formed. The void 53 is formed between the front waist sheet 20 and the body H when the absorbent core 51 is thicker than constituent elements such as other sheets and the body side liner 52 contacts the body H of the wearer. borrow Since the voids 53 are formed between the body H of the wearer and the disposable diaper 1, the air permeability in the disposable diaper 1 can be improved. In particular, since the voids 53 are formed on both sides of the absorber 50 which is easy to increase the humidity due to absorption of body fluids, the stuffiness in the disposable diaper 1 can be more effectively suppressed.

In the present embodiment, the absorbent body 50 extends only in the inner region 62 in the rear waist portion sheet 30, but may extend in the intermediate portion 66 and the outer region 64. At this time, in the back waist sheet 30, the same void as the gap 53 of the front waist sheet 20 is formed.

Further, inner layer sheets 21 and 31 are disposed on the skin facing surfaces of the intermediate portions 65 and 66 of the front and rear waist sheets 20 and 30, respectively. Since the crotch sheets 40 are not overlapped in the intermediate regions 65, 66, when the disposable diaper 1 is worn, in the intermediate portions 65, 66, the inner sheets 21, 31 directly contact the skin of the wearer. That is, the inner sheet 21, 31 contacts the wearer's skin in a wider range than when the crotch sheet 40 overlaps the intermediate regions 65, 66 and contacts the wearer's skin. Since the inner layer sheets 21 and 31 are composed of an elastic fiber nonwoven fabric, the front and rear waist regions 12 and 13 of the disposable diaper 1 can be adhered to the wearer's skin in a wide range, and the touch feeling can be improved.

The constituent members of the disposable disposable diaper 1 are provided without any particular mention. Except for the materials described in the present specification, various well-known materials commonly used in the field may be used without any limit. In addition, the terms "1st", "2nd", "3rd" and "4th" used in the specification and the scope of the patent application are merely used to distinguish the same elements, positions, and the like.
