FIGS. 1 and 2 are views showing an adult diaper which is one embodiment of the present invention. In FIG. 2, each elastic member is shown in an expanded state for the purpose of explanation. As illustrated, the diaper 10 includes a side seat 50 and a chassis 20. The diaper 10 has a skin contact surface and a non-skin contact surface, and includes a front waist region 11, a rear waist region 12, and a crotch region 13 positioned between the front and

rear waist regions

11, 12. . Here, a skin contact surface shows the upper surface in the diaper 10 developed to the state of FIG. 2, and a non-skin contact surface shows the opposite surface. Therefore, as apparent from FIG. 1, when the diaper is actually worn, at least a part of the skin contact surface of the side sheet 50 does not directly contact the wearer's skin.

The chassis 20 includes an inner surface sheet 21 positioned on the skin contact surface, an outer surface sheet 22 positioned on the non-skin contact surface, a liquid absorbing structure 40 positioned between the inner and

outer surface sheets

21 and 22, and a liquid absorbing A pair of leak-proof cuffs 60 arranged along the side edges of the pair of liquid absorbing structures extending in the longitudinal direction Y of the structure 40, that is, extending in the longitudinal direction across the front waist region, the crotch region, and the rear waist region. Including.

The rear waist region 12 has a pair of first side edges 14 extending in the longitudinal direction Y, and the front waist region 11 has a pair of second side edges 15 extending in the longitudinal direction Y. The side seats 50 are respectively attached. The side sheet 50 has a proximal region 51 in the vicinity of the first side edge 14 and a distal region 52. An engagement member 31 that is a hook element of a mechanical fastener is attached to the distal region 52. In the diaper 10 shown in the figure, the portion of the distal region 52 where the engaging member 31 is located has a shape protruding in two tabs, but this portion may be one or three or more. Moreover, you may continue over the whole area of the vertical direction Y of the side seat | sheet 50. The distal region 52 has higher rigidity than the proximal region 51 and keeps the engaging member 31 stable. The clothing side of the front waist region 11 is formed of a fiber nonwoven fabric that detachably engages with the engagement member 31. Such a fiber nonwoven fabric extends from one second side edge portion 15 to the other second side edge portion 15 in substantially the entire lateral direction X of the front waist region 11, so that the size of the waist of the wearer is increased. In addition, the engagement position of the engagement member 31 can be adjusted.

The engagement member 31 formed as described above is engaged with the clothing side of the front waist region 11 so that the front and

rear waist regions

11 and 12 are connected to each other, and the diaper 10 is shown in FIG. It can be formed into a shape.

In the diaper 10 as described above, the chassis 20 includes front and rear end edges 17 and 18 extending in the lateral direction X, and a plurality of waist elastic members 81 can contract in the lateral direction X along the rear end edge 18. It is attached.

The

elastic members

81 and 82 are between the inner and

outer surface sheets

21 and 22 and are joined to at least one of the

sheets

21 and 22 in an extended state.

Further, the leak-proof cuff 60 is joined to the skin contact surface of the chassis 20 at the front and

rear end portions

61 and 62 and the fixed edge portion 64 (see FIG. 2), and is joined in an elongated state at the free edge portion 63. The elastic member 65 which can be expanded-contracted to Y is included. With such a configuration, the leak-proof cuff 60 moves away from the skin contact surface or rises due to the contraction of the elastic member 65, and fits the wearer's skin at the free edge 63. It has a tendency to be separated from the skin of the wearer. Therefore, it is possible to catch the excrement without leaking without making a gap between the leak-proof cuff 60 and the skin of the wearer.

3 to 5 show a first embodiment in the first aspect of the present invention. 3 is a partial view of the diaper of FIG. 1 fixed in a separable manner in this embodiment as seen from the non-skin contact surface, and FIG. 4 is a view taken along the line IV-IV in FIG. 5 (a) to (d) show the steps up to FIG. 4 in the same cross section as FIG. As shown in FIG. 5, the side seat 50 is (a) a non-skin contact of the side seat 50 at a folding line 71 extending in the longitudinal direction Y located at or near the boundary between the distal region 52 and the proximal region 51. (B) is joined to the outer surface sheet 22 forming the rear waist region at the second joint portion 92 located at the end in the lateral direction X of the side seat 50 in the proximal region 51, and (c) ) Adhesive is applied to the non-skin contact surface on the temporary fixing portion 90 extending in the vertical direction Y in the proximal region 51, and (d) in the vertical direction Y between the temporary fixing portion 90 and the second joint portion 92. The folding line 72 is further folded in the same direction as the folding line 71. Thereafter, the liquid absorption structure 40 is joined to the outer surface sheet 22, and the leak-proof cuff 60 is joined at the first joint portion 91 located at the position overlapping the second joint portion 92 via the side sheet 50. The inner sheet 21 is joined to the side sheet 50. Through the above steps, as shown in FIG. 3, the side sheet 50 is fixed to the outer sheet 22 that forms the chassis 20.

At this time, since the engaging member 31 is covered by the skin contact surface of the side seat 50, the engaging member 31 is not painfully used due to contact with a hard place in the state of FIG. Or inadvertently adhering to other parts of the diaper 10 or clothes of the operator.

Also, the order of steps (a) to (d) can be partially exchanged. For example, the inner sheet 21 and the outer sheet 22 may be bonded to the side sheet 50 in advance.

The fixing performed in the step shown in FIG. 5 fixes the side sheet 50 to the non-skin contact surface of the chassis 20, so even when the adhesive remains on the chassis 20 when the fixing is separated, the skin of the wearer There is no contact.

6 to 8 show a second embodiment in the second aspect of the present invention. FIG. 6 is a view similar to FIG. 3 detachably fixed in this embodiment, and is a partial view seen from the skin contact surface. FIG. 7 is a view taken along the line VII-VII in FIG. 8A to 8D show the steps up to FIG. 7 in the same cross section as FIG. In this aspect, the non-skin contact surface of the side seat 50 is fixed to the skin contact surface of the chassis. Specifically, for example, as shown in FIG. 8, the side seat 50 is (a) a side at a folding line 73 extending in the longitudinal direction Y located at or near the boundary between the distal region 52 and the proximal region 51. Folded in the direction in which the skin contact surfaces of the sheet 50 overlap with each other, and (b) on the temporary fixing portion 90 extending in the longitudinal direction Y between the position having the engagement member 31 on the skin contact surface and the folding line 73. Adhesive is applied to the skin contact surface, and (c) is separably fixed to the leak-proof cuff 60 joined to the skin contact surface of the inner surface sheet 21 by the adhesive. The inner sheet 21 is sandwiched between the side sheets 50 by folding the side sheet 50 with a folding line 74 extending in the direction Y, and the inner sheet 21 is formed at the first joint portion 91 at the end in the lateral direction X of the side sheet 50 in the proximal region 51. And joining It is. Thereafter, the liquid absorbing structure 40 is joined to the outer surface sheet 22 that has been joined in advance at the second joining portion 92 that is positioned so as to overlap the first joining portion 91 via the side sheet 50. As shown in FIG. 6, the side sheet 50 is fixed to the skin contact surface of the chassis 20 by the above process.

At this time, since the engaging member 31 is covered with the skin contact surface of the side sheet 50, the engaging member 31 is not painfully used due to contact with a hard place in the state of FIG. Or inadvertently adhering to other parts of the diaper 10 or clothes of the operator.

Further, the separable fixing in the second aspect can also be performed by the third embodiment shown in FIGS. FIG. 9 is a view similar to FIG. 3 fixed in a separable manner in this embodiment, and is a partial view seen from the skin contact surface. FIG. 10 is a view taken along line XX in FIG. 11A to 11E show the steps up to FIG. 10 in the same cross section as FIG. Specifically, for example, as shown in FIG. 8, the side seat 50 is (a) a folding line extending in the longitudinal direction Y located in the vicinity of the boundary on the proximal region 51 side of the engagement member 31 in the distal region 52. 75, the skin contact surfaces of the side seats 50 are folded in the overlapping direction, and (b) a folding line 76 located inward of the folding line 75 and extending in the longitudinal direction Y is further folded in the same direction as the folding line 75. (C) The adhesive is applied to the non-skin contact surface on the temporary fixing portion 90 extending in the vertical direction Y between the position where the engagement member 31 is provided on the skin contact surface and the folding line 75. d) Removably fixed to the skin contact surface of the inner sheet 21 to which the leak-proof cuff 60 is joined by the adhesive, and (e) the side sheet 50 is bent by the folding line 77 extending in the longitudinal direction Y in the proximal region 51. By folding the side seat 50 Sandwiches the facing sheet 21 is bonded to the inner sheet 21 in the first joint portion 91 in the lateral direction X of the end of the side sheet 50. Thereafter, the liquid absorbing structure 40 is bonded to the outer sheet 22 that is bonded in advance at the second bonding portion 92 that is located at a position overlapping the first bonding portion 91 via the side sheet 50. The engagement member 31 is more stably covered with the side seat 50 by folding in the above process.

In the present invention, the fixing between the side seat 50 and the chassis 20 must be a separable fixing that can be easily removed during use. The separable fixing strength is preferably 6 N / 25 mm or less under the condition of a tensile tester 100 mm / min, and more preferably 1.5 N / 25 mm or less under the same condition. Such separable fixing can be achieved by using a hot-melt adhesive having a small tack force, for example, an SBS copolymer hot-melt adhesive, as the adhesive. Specifically, a hot melt adhesive having a tack force of 1 ounce (about 28.35 g) / 25 mm or less is preferable. Here, the tack force is measured based on a loop tack method based on JIS Z 0237. Specifically, the joint part to which the adhesive is applied is cut to a width of 25 mm to prepare a sample, and a loop is formed and set in a tensile tester. A T-shaped stainless plate is applied from below the sample and adhered to the joint of the sample. The stainless steel plate is moved downward at a speed of 300 mm / min, and the tensile force when the stainless steel plate and the sample are peeled is measured to obtain the tack force.

Moreover, in these separable fixings, the hot melt adhesive having a small tack force may be applied intermittently in the longitudinal direction Y. This is preferable because the strength required for maintenance is smaller per unit area of the adhered portion.

Further, in the fixing performed in the steps shown in FIGS. 8 and 11, the side seat 50 is fixed to the skin contact surface of the chassis 20, unlike the fixing in FIG. Therefore, when this fixing is separated, it is necessary to prevent the adhesive from remaining on the chassis 20 so that the remaining adhesive does not cause the skin trouble of the wearer.

The above-described problem can be achieved by applying the hot melt adhesive to the side sheet 50 and adhering it to the inner surface sheet 21 until it reaches room temperature. For example, in the production line, the side sheet 50 is folded and brought into contact with the inner surface of the chassis 20 between the time when the hot melt adhesive is applied on the temporary fixing portion 90 and the temperature reaches room temperature, and the sheet is pressed between press rolls. Also good. Here, the hot-melt adhesive is applied to the side sheet 50 in a melted state, but has a high viscosity when fixed to the chassis 20, so that the hot-melt adhesive penetrates into the sheet itself constituting the chassis 20. There is nothing to do. By fixing the side sheet 50 and the chassis 20 in such a manner as to be separable, the adhesive is separated from the chassis 20 together with the side sheets 50 so that it hardly remains on the chassis 20. It is possible to suppress skin troubles due to contact with the wearer's skin. Specifically, when separated from the side sheet 50, it is possible to prevent an amount of adhesive that can be visually recognized by the naked eye from remaining on the chassis 20.

In the first to third embodiments, it is possible to further increase the number of times of folding. For example, in each embodiment, only the part having the engaging member 31 in the side flap 50 may be folded in the direction in which the skin contact surfaces first overlap each other.

Other joints for constituting the diaper 10 are stronger than these separable fixations, that is, have a strength that does not peel even when worn or pulled in a normal diaper use state. For example, it can be joined using a hot melt adhesive having a tack force stronger than that used for separable fixing. Alternatively, means commonly used in the field such as welding of a thermoplastic sheet by heat sealing, sonic sealing, or the like may be used.

In the present invention, as a hot melt adhesive coating method, other general coating methods such as spiral coating, omega coating, control seam coating, bead coating, slot coater coating and the like can be used. .

In the first to third embodiments, the diaper 10 includes the leak-proof cuff 60, but it is also possible to implement the present invention in a diaper without the leak-proof cuff. Moreover, in 2nd Embodiment, the side seat | sheet 50 is being fixed to the leak-proof cuff 60 so that isolation | separation is possible. Such a configuration is preferable because, for example, the side sheet 50 can be fixed without damaging the inner sheet 21 on the liquid absorbing structure 40. However, for example, as in the third embodiment, the side sheet 50 may be detachably fixed to the inner surface sheet 21 instead of the leak-proof cuff 60.

Further, in the diaper 10, the side sheet 50 is formed as a separate member from the inner and

outer surface sheets

21 and 22, and is attached between these two sheets, but the skin contact surface of the inner surface sheet or the non-skin of the outer surface sheet It may be attached to the abutting surface, or one or both of the inner and

outer surface sheets

21 and 22 may continuously form the side seat 50 from the rear waist region. Further, the distal region 52 may be formed of a separate member from the proximal region 51, or may be formed of a sheet continuous from the proximal region 51 and reinforced by a separate member. Further, the side seat 50 may be extendable in the lateral direction X by disposing an elastic member.

In the diaper 10, the engagement member 31 is a hook member of a mechanical fastener, but the present invention is not limited to this. For example, the engaging member may be an adhesive. Further, the diaper 10 is configured so that the engagement member 31 engages with the fiber nonwoven fabric forming the clothing side of the front waist region 11, but the front waist region 11 can be engaged with the engagement member 31. You may have a 2nd engagement member. For example, when the engaging member 31 is a hook member of a mechanical fastener, the front waist region 11 may have a second engaging member made of a loop member of a mechanical fastener.

Moreover, in the diaper 10, the chassis 20 includes the liquid absorbing structure 40 sandwiched between the inner and

outer surface sheets

21, 22, but the present invention is not limited to such a configuration. For example, a diaper having an absorbent chassis in which a liquid-absorbing structure covered with a liquid-permeable sheet is fixed to the skin contact surfaces of the inner and outer surface sheets forming the entire chassis can be implemented. In another example, a belt-like waist member that forms a front waist region and a rear waist region, and a crotch member that forms a crotch region and is formed of a liquid-impervious sheet, the skin contact surface of the crotch member A diaper having an absorbent chassis to which a liquid-absorbing structure covered with a liquid-permeable sheet is fixed is also feasible. When the liquid-absorbing structure is covered with the liquid-permeable sheet, it may be covered with the liquid-permeable sheet only on the skin contact surface, or the entire liquid-absorbing structure is wrapped with the liquid-permeable sheet. Also good.

In the present invention, as the liquid-permeable sheet for forming the inner sheet 21 and the like, the liquid-impervious sheet for forming the outer sheet and the leakage-proof cuff, etc. As a liquid-absorbing structure such as a moisture-permeable and liquid-impermeable plastic film or a laminate of a moisture-permeable and liquid-impermeable plastic film and a fiber nonwoven fabric, fluff pulp fibers and superabsorbent polymer particles, and optionally thermoplastic staple fibers As an elastic member, natural rubber, synthetic rubber, stretchable fiber nonwoven fabric, etc., as the side sheet 50, a fiber nonwoven fabric, a porous plastic film, etc. Individual materials or their laminates, etc. It may what is used which is commonly Te. As the fiber nonwoven fabric, a hydrophobic synthetic fiber nonwoven fabric having a mass of 15 to 45 g / m ² can be used.

In the present invention, the diaper 10 is described by an embodiment in which the first waist region is the front waist region and the second waist region is the rear waist region. It is also possible to implement the area as the front waist area.

In this way, the diaper 10 is shipped in a state where the entire diaper 10 is appropriately folded after the side sheet 50 is separably fixed to the state of FIG. 3, FIG. 6 or FIG.
