Description

  The present invention relates to a disposable wearing article, and more particularly to a disposable wearing article such as a disposable diaper having a pair of longitudinally extending cuff sheets, disposable toilet training pants, disposable incontinence pants, and disposable sanitary pants.

  Conventionally, a wearing article having a pair of cuff sheets extending in the vertical direction is known. For example, Patent Document 1 discloses a disposable diaper having a top sheet, a leak-proof sheet, an absorbent main body, and an outer layer body located outside the absorbent main body. The absorbent main body is provided with a three-dimensional guard (cuff sheet), and the three-dimensional guard is erected by the expansion and contraction of the three-dimensional guard elastic member, thereby preventing liquid from flowing out in the width direction of the absorbent main body.

JP 2002-291798 A (JP2002-291798A)

  In Patent Document 1 as described above, the three-dimensional guard is fixed to the absorbent main body on the outer side in the width direction, and the three-dimensional guard elastic member is attached without fixing the inner side in the width direction. The width direction inner side where the three-dimensional guard elastic member was attached closely_contact | adheres to a wearer's buttocks, and prevents the leakage of excrement. However, when excrement is absorbed by the absorbent main body, the absorbent main body becomes heavier and hangs downward, and the three-dimensional guard is pulled downward, so that the inside is separated from the wearer's buttocks.

  In this invention, while making a pair of cuff sheet | seat located in a skin opposing surface closely_contact | adhere to a wearer's buttocks, it aims at providing the disposable wearing article which can prevent that an absorber hangs down during wear.

  The present invention has a longitudinal direction and a lateral direction, and has a skin facing surface and a non-skin facing surface which is the opposite side, a front and rear waist region, a crotch region located between these front and rear waist regions, and dimensions in the lateral direction. A chassis having a virtual vertical center line that bisects the body, an absorber positioned at least in the crotch region, and a pair of cuff sheets positioned on the skin-facing surface of the chassis and spaced apart in the lateral direction. The present invention relates to an improvement of a disposable wearing article including a leg elastic body attached along both side edges of the chassis.

The present invention provides the disposable wearing article, wherein the cuff sheet includes a proximal edge joined to the chassis, a distal edge that is separable from the chassis, the proximal edge, and the distal edge. And a virtual folding line extending in the vertical direction and positioned between the first edge and the proximal edge, the first joint extending continuously in the lengthwise direction, and the lateral side of the first joint. The cuff seat is formed along the front and rear edges of the cuff sheet, and is joined to the chassis by second joints spaced apart from each other in the longitudinal direction. It is joined to the proximal edge by a third joint that is positioned overlapping the joint and spaced apart from each other in the longitudinal direction, and expands and contracts in the longitudinal direction between the third joints separated in the longitudinal direction. Possible and extending at least in the longitudinal direction A pair of distal elastic bodies, wherein at least a part of the second and third joints are formed to overlap the absorber, and the leg elastic bodies extend along both side edges of the chassis. A front leg elastic body having a portion and a central portion extending in the lateral direction between the side edge portions, the side edge portions and the central portion being continuous and extending from the front waist region toward the crotch region And a rear leg elastic body extending from the rear waist region toward the crotch region, the central portion traverses the virtual longitudinal center line and overlaps the absorber, and more than the distal edge portion. The front and rear waist region extends inward in the lateral direction, and has a waist elastic body that can extend and contract in the lateral direction and extends in the lateral direction, and the absorber extends from the crotch region to the front and rear waist region. When Moni, the overlapping waist elastic member in the longitudinal leg elastics, tensile stress of the central portion, and greater than the tensile stress of the both side edge portions.

  In accordance with one or more embodiments of the present invention, at least three distal elastic bodies may be retractably attached to the distal edge of the cuff sheet so that the distal edge can be worn by the wearer. Even when the distal edge is pressed by the wearer, the movement of the distal edge due to the pressing is relieved by the distal elastic body, and the entire distal edge is enlarged. There is no movement. Therefore, the distal edge is not separated from the wearer's buttocks and can be kept in close contact. Further, the leg elastic body has a central portion extending across the virtual longitudinal center line, and the absorbent body is lifted toward the wearer by the central portion, so that the absorbent body does not hang down, and the associated distal portion It is possible to prevent the separation from the buttocks. Furthermore, since the absorbent body is pressed toward the wearer's body by the front and rear waist elastic bodies, the absorbent body can be further prevented from hanging down.

The perspective view which shows the wearing condition of the disposable diaper which is one Embodiment of a disposable wearing article. The top view seen from the skin opposing surface of the developed diaper. The exploded perspective view of a diaper. The IV-IV line expanded sectional view of FIG. The VV line expanded sectional view of FIG. The schematic diagram which shows the partial structure of a diaper. Sectional drawing similar to FIG. 4 in the wearing condition of a diaper.

  1 to 5, the diaper 1 has a longitudinal direction Y and a lateral direction X, a front waist region 11 and a rear waist region 12, a crotch region 13 positioned between these front and rear waist regions 11, 12, It has front and rear end edges 14 and 15 extending in the direction X, and both side edges 16 extending in the longitudinal direction Y. In addition, in FIGS. 2-6, each elastic body is shown in the state extended against the contraction force.

  The diaper 1 has a virtual vertical center line PP that bisects the dimension in the horizontal direction X and a virtual horizontal center line QQ that bisects the dimension in the vertical direction Y. Nearly symmetric at -P. Some of the same components that are made symmetrical are omitted in the drawings.

  The diaper 1 is a liquid-impervious or liquid-impervious cover sheet 20 positioned on the skin facing surface, a back sheet 30 positioned on the non-skin facing surface on the opposite side, and between these sheets 20, 30. The absorbent body 40 positioned, the liquid-permeable body-side liner 50 positioned between the cover sheet 20 and the absorber 40, the pair of cuff sheets 60 attached to the body-side liner 50, the absorber 40, and the back sheet 30 And a liquid-impervious or liquid-impervious leakproof sheet 70 positioned between the two. The body side liner 50 and the back sheet 30 form the diaper chassis 10 according to the embodiment.

As the back sheet 30, for example, a spunbond / meltblown / spunbond (hereinafter referred to as SMS) non-woven fabric or a spunbond non-woven fabric having a mass of about 10 to 30 g / m ² can be used.

  A leak-proof sheet 70 is joined to the back sheet 30 by a known joining means such as a hot melt adhesive (not shown). As the leak-proof sheet 70, a liquid-permeable plastic film that is hardly liquid-permeable, preferably liquid-impermeable and breathable can be used. The leak-proof sheet 70 has a larger area than the absorber 40 and prevents excrement such as urine from leaking from the diaper 1.

  The absorber 40 is attached to the leak-proof sheet 70 by a known joining means such as a hot melt adhesive (not shown). The absorber 40 extends from the crotch region 13 to the front and rear waist regions 11 and 12, and can absorb excrement such as urine in a relatively wide range. The absorbent body 40 is formed by covering a liquid-absorbent core material with a liquid-diffusible covering sheet such as tissue paper. Wood fluff pulp, superabsorbent polymer particles, or a mixture thereof can be used as the core material. The core material and the covering sheet can be joined to each other using a known joining means such as a hot melt adhesive (not shown).

The body side liner 50 is attached to the absorber 40 by a known joining means such as an intermittently applied hot melt adhesive (not shown). As the body side liner 50, for example, a spunbond fiber nonwoven fabric or a point bond fiber nonwoven fabric having a mass of about 15 to 35 g / m ² , preferably about 18 to 23 g / m ² can be used. The body-side liner 50 has a substantially rectangular shape, and is smaller in size in the vertical direction Y and the horizontal direction X than the back sheet 30 and is sized to cover substantially the entire surface of the absorber 40.

A pair of cuff sheets 60 that are spaced apart in the lateral direction X are attached to the body side liner 50. As the cuff sheet 60, for example, an SMS fiber nonwoven fabric having a mass of about 10 to 30 g / m ² can be used. FIG. 6 is a view showing a laminated state of the cuff sheet 60, the body side liner 50, and the absorber 40, and is partially broken for explanation. Further, since these components are symmetric with respect to the virtual vertical center line PP, some of them are omitted. The cuff sheet 60 includes front and rear end edges 61 and 62 extending in the lateral direction X, a proximal edge 63 extending in the longitudinal direction Y and joined to the body side liner 50, and a distal edge separable from the body side liner 50. Part 64. The front and rear end edges 61 and 62 of the cuff sheet 60 are overlapped so as to coincide with the front and rear end edges 51 and 52 of the body side liner 50.

  As shown in FIGS. 5 and 6, a virtual folding line 66 extends in the longitudinal direction Y between the proximal edge 63 and the distal edge 64 of the cuff sheet 60. The distal edge 64 is bent along the virtual folding line 66 so as to overlap the proximal edge 63. The proximal edge 63 as described above is formed by the first joint 81 extending continuously in the longitudinal direction Y and the second front and rear joints 82 and 83 located on the outer side in the lateral direction X than the first joint 81. It is joined to the side liner 50. The second front and rear joint portions 82 and 83 are formed along the front and rear end edges 61 and 62 of the cuff sheet 60 and are separated in the vertical direction Y. The second front and rear joint portions 82 and 83 are formed at positions where at least a part thereof overlaps the core material of the absorber 40.

  A third joint portion 84 is formed between the distal edge portion 64 and the proximal edge portion 63 which are folded and overlapped, and are joined to each other via the cuff sheet 60. The third joint portion 84 overlaps with the second front and rear joint portions 82 and 83 via the cuff sheet 60 and is spaced apart in the longitudinal direction Y.

  A sleeve is formed by the cuff sheet 60 on the distal edge 64, and a distal elastic body 65 extending in the longitudinal direction Y is attached to the distal edge 64 so as to be retractable in an extended state. The distal elastic body 65 includes first to third elastic bodies 65a, 65b, and 65c, and the first elastic body 65a is positioned at the end of the cuff sheet 60 that is folded into a sleeve shape.

  FIG. 4 shows a state where the left side elastic body 65 is stretched against the contraction force on the left side, and the right side is that the distal edge 64 is separated from the body side liner 50 by the contraction force of the distal elastic body 65. Indicates the state. Further, on the right side of FIG. 4, the rear leg elastic body 94 is also contracted, and the chassis 10 is lifted upward in the drawing. Since the distal edge portion 64 is separable from the body side liner 50 between the second front and rear joint portions 82 and 83 and the third joint portion 84 in the longitudinal direction Y, as shown on the right side of FIG. By the contraction of the distal elastic body 65, the distal elastic body 65 moves away from the body side liner 50.

  FIG. 7 is a view similar to FIG. 4 when the diaper 1 is worn. A two-dot chain line in FIG. 7 indicates a crotch portion of the wearer. As illustrated, when the diaper 1 is worn, the distal edge 64 of the cuff sheet 60 is separated from the body-side liner 50 and stands up toward the wearer's skin. If it does so, the area | region to which the distal elastic body 65 was attached will contact a wearer's inseam | crotch in a surface with the 1st elastic body 65a facing outside. In such a state, when the wearer moves, the distal edge portion 64 may be pushed inward in the lateral direction of the drawing. That is, the first elastic body 65a is pressed toward the second elastic body 65b. However, since the distal edge portion 64 is in contact with the wearer on the surface, the standing distal edge portion 64 is unlikely to fall down and can be kept in close contact with the wearer. In addition, since the second and third elastic bodies 65b and 65c are respectively extended, even if the first elastic body 65a is pressed against the second elastic body 65b, the second elastic body 65b becomes the third elastic body. It is possible to prevent the entire distal edge 64 from moving inward in the lateral direction X and being separated from the wearer only by being bent toward the 65c side. Moreover, since the distal edge part 64 is hard to fall down, the separated state in the lateral direction X of the cuff sheet 60 can be maintained, and the excreta absorption region can be maintained widely.

  If the distal elastic body 65 is the first elastic body and the second elastic body 65, when the first elastic body is pressed inward in the lateral direction of the drawing, the sheet is interposed between the second elastic body and the second elastic body. Then, the movement is transmitted to the second elastic body, and the second elastic body also moves inward, and as a result, the entire distal edge portion 64 falls inward. However, by attaching three or more distal elastic bodies 65, it is possible to prevent the movement of the first elastic body from being transmitted to the third elastic body and beyond, and the entire distal edge portion 64 falls inward. Can be prevented. Therefore, any number of distal elastic bodies 65 may be attached as long as there are three or more.

  The distal edge 64 is formed by two sheets at the end to which the distal elastic body 65 is attached, and the other part is formed by one sheet. And the distal edge 64 tends to bend at the boundary. Thus, even further, the distal edge 64 can contact the wearer at the surface.

As shown in FIGS. 2 and 3, the cover sheet 20 is attached to the skin facing surface of the cuff sheet 60. As the cover sheet 20, for example, a spunbond fiber nonwoven fabric or a point bond fiber nonwoven fabric having a mass of about 15 to 35 g / m ² , preferably about 18 to 23 g / m ² can be used. The cover sheet 20 has an outer shape that is substantially the same shape and size as the back sheet 30, and an opening 21 that penetrates in the thickness direction is formed at the center. The cover sheet 20 overlaps the first joint 81, the second front / rear joints 82 and 83, and the third joint 84 formed on the cuff sheet 60, and the opening 21 extends into the opening 21. It is sized so as not to come out. Further, the opening 21 has a smaller area than the body side liner 50, and a part of the distal edge 64 of the cuff sheet 60 is exposed from the opening 21 and protrudes toward the wearer's skin when worn.

  The excrement is excreted from the opening 21 of the cover sheet 20 toward the absorber 40 via the cuff sheet 60. The periphery of the cover sheet 20 is bonded to the back sheet 30 by a known bonding means such as a hot melt adhesive (not shown). Therefore, even if excrement flows out between the cuff sheet 60 and the cover sheet 20, it can be prevented from leaking by the cover sheet 20. Further, by holding the excrement between the cover sheet 20 and the back sheet 30, it is possible to prevent the excrement from adhering to the wearer's skin and to prevent the wearer's skin irritation.

  In the vicinity of the front and rear end edges 61 and 62 of the cuff sheet 60, the overlapping of the cover sheet 20 prevents the distal edge 64 from standing up, but the cover sheet 20 has the second front and rear joints 82 and 83 of the distal edge 64. It is arranged to overlap. Therefore, the cover sheet 20 does not greatly affect the standing property of the distal edge portion 64.

  Front and rear waist elastic bodies 91 and 92 and front and rear leg elastic bodies 93 and 94 are attached between the back sheet 30 and the leak-proof sheet 70. As the front and rear waist elastic bodies 91 and 92, a strand shape or a string shape having a thickness of about 310 to 940 dtex can be used. The front and rear waist elastic bodies 91 and 92 are attached to the front and rear waist regions 11 and 12 so as to be contractible in an extended state in the horizontal direction X, and a plurality of front and rear waist elastic bodies 91 and 92 are attached to be separated in the vertical direction Y. These front and rear waist elastic bodies 91 and 92 are continuously extended without being cut in the lateral direction X. Since the absorbent body 40 extends from the crotch region 13 to the front and rear waist regions 11 and 12, at least a part of the front and rear waist elastic bodies 91 and 92 overlaps the non-skin facing surface of the absorbent body 40. Therefore, the front and rear end edge portions 41 and 42 of the absorber 40 are pressed against the wearer's skin by the contraction force of the front and rear waist elastic bodies 91 and 92, and excrement leaks from the front and rear end edges 14 and 15 of the diaper 1. Can be prevented.

  As the front and rear leg elastic bodies 93 and 94, a strand shape or a string shape having a thickness of about 470 to 940 dtex can be used. The front and rear leg elastic bodies 93, 94 are disposed between the side edge portions 93 a, 94 a extending along the side edges 16 of the chassis 10 and the side edge portions 93 a, 94 a and across the virtual vertical center line PP. And central portions 93b and 94b extending to X. At least the central portions 93 b and 94 b overlap the absorber 40, and the central portion 93 b of the front leg elastic body 93 and the central portion 94 b of the rear leg elastic body 94 intersect with each other via two intersection points 95.

  As described above, since the central portions 93b, 94b of the front and rear leg elastic bodies 93, 94 overlap the absorber 40, the absorber 40 can be lifted toward the wearer's body and excreted by the absorber 40. Even if an object is absorbed and becomes heavy, it can be prevented from separating from the body. Further, when the absorber 40 is separated from the body, it may be pressed against the wearer's thigh and the apparent dimension in the lateral direction X may be reduced, but the absorber 40 is prevented from being separated from the body. This can prevent this. At the intersection point 95, the contraction force by the front and rear leg elastic bodies 93 and 94 is concentrated and increased, and therefore the absorber 40 can be reliably pressed to the skin side of the wearer at the intersection points 95 and 96. Furthermore, since the front and rear leg elastic bodies 93 and 94 are continuously formed in the side edge portions 93a and 94a and the central portions 93b and 94b, the contraction force is not divided and the absorber 40 is further separated. It becomes possible to press against the skin side of the wearer.

  Gasket cuffs 17 are formed in the vicinity of both side edges 16 of the chassis 10 by the side edge portions 93a, 94a of the front and rear leg elastic bodies 93, 94, and the leg openings can be brought into close contact with the wearer. Therefore, it is possible to prevent leakage of excrement from the leg opening.

  In the diaper 1 as described above, the cuff sheet 60 can be securely adhered to the wearer's buttocks or the vicinity thereof by the three distal elastic bodies 65, and the central portions 93b of the front and rear leg elastic bodies 93, 94 are provided. Since the absorbent body 40 is held on the wearer side by 94b, the cuff sheet 60 can be further prevented from being separated from the buttocks or the vicinity thereof. Furthermore, since the absorbent body 40 is also brought into close contact with the body side by the front and rear waist elastic bodies 91 and 92 that are continuous in the lateral direction X, it can quickly absorb excrement and prevent leakage. Further, it is possible to prevent the absorber 40 from sliding down, and to prevent the cuff sheet 60 from being separated from the collar portion due to the absorber 40 sliding down.

  The cuff sheet 60 is folded by the folding line 66, so that when the cuff sheet 60 is extended, the dimension in the lateral direction X of the distal edge 64 standing up toward the buttocks can be increased. That is, the standing dimension toward the buttock can be increased. When the standing dimension of the distal edge portion 64 is increased, the absorbent body 40 may be largely separated from the wearer. In this embodiment, the absorbent body 40 is moved to the body side by the front and rear leg elastic bodies 93 and 94. Since it presses, it can prevent that the absorber 40 leaves | separates greatly from a wearer.

As the front and rear waist elastic bodies 91 and 92 and the front and rear leg elastic bodies 93 and 94, elastic bodies in the form of strings or strands are used, but elastic stretchable nonwoven fabrics or the like having elasticity can also be used. Further, the central portions 93b and 94b of the front and rear leg elastic bodies 93 and 94 are made to have a higher tensile stress than the side edge portions 93a and 94a. Therefore, no wrinkles are formed on the absorbent body 40 at the central portions 93b and 94b, and the entire absorbent body 40 can be pressed against the body side. The front and rear leg elastic bodies 93 and 94 intersect each other in the crotch region 13, but may be separated in the longitudinal direction Y without intersecting.

  The central portions 93b and 94b of the front and rear leg elastic bodies 93 and 94 extend continuously in the horizontal direction X beyond the virtual vertical center line PP, but they are divided in the vicinity of the virtual vertical center line PP. It may be. In this case, it is preferable that the end portions of the central portions 93b and 94b extend beyond the distal edge portion 64 to the inside in the lateral direction X. When the front and rear leg elastic bodies 93 and 94 overlap the distal edge portion 64, the distal edge portion 64 can be pressed against the skin of the wearer and brought into close contact with the skin. In addition, the front and rear waist elastic bodies 91 and 92 are attached so as to overlap the absorber 40, but only one of them may overlap the absorber 40.

  In this embodiment, the first joining portion 81 is located outside the absorbent body 40 in the lateral direction X so as not to overlap the absorbent body 40. It can be suitably used for a month-old infant. The younger infants have soft stools, and can sufficiently hold soft stools by enlarging a pocket formed between the cuff sheet 60 and the body side liner 50. Further, the first joint 81 may be formed at a position overlapping the absorber 40. The diaper in this case can be suitably used for, for example, an older infant.
