In FIG. 2, two two-dot chain lines that divide the disposable auxiliary pad 1 into approximately three equal parts are drawn, the center portion 16 is between the two-dot chain lines, and the outer portions of the two-dot chain lines are the side edges 15, 17 and so on.

  The disposable auxiliary pad 1 is provided with fastening members 10 and 11 on the back side of the back sheet 3. Here, a back surface side is a lower side toward FIG. 3, and is a side which faces the inner surface of a wearer's diaper main body. The upper side toward FIG. 3 is the side facing the wearer's skin. The front fastening member 10 is disposed on both side edge portions 15 and 17 of the front side portion 12, respectively. The rear fastening member 11 is disposed in both side edge portions 15 and 17 in the rear side portion 14. The front and rear fastening members 10 and 11 are depicted as rectangular shapes each having an end edge 29 in the length direction and a side edge 30 in the width direction. However, the shape is not limited to this shape.

  The fastening members 10 and 11 are preferably surface fasteners having hook members. The hook member is preferably a thin and flexible member made of a plastic member such as polyethylene or polypropylene, and preferably has a plurality of hook members standing on a base sheet as a base.

  The fastening members 10 and 11 made of hook members are attached to the back surface of the back sheet 3 so that the hook members face the inner surface of the diaper main body. The disposable auxiliary pad 1 is joined to the diaper body by the hook member engaging the inner surface of the diaper body. If the fastening member is a hook member, it can be repeatedly attached, the position can be easily adjusted, and damage to the inner surface of the diaper main body is reduced.

  The width direction side edge 30 of each fastening member is preferably arranged along the side edge 22 of the disposable auxiliary pad 1. Further, the length 26 of the side edge 30 is preferably longer than the length 31 of the end edge 29. Due to the arrangement relationship and the dimensional relationship of such fastening members, when the disposable auxiliary pad 1 is fixed to the diaper body, it is possible to make it difficult to cause a shift in the length direction. Since the displacement does not easily occur, the disposable auxiliary pad continues to fit in an appropriate position between the wearer's crotch, thereby preventing leakage of excrement such as urine.

  The fastening member is preferably provided separately from the side edge 22 in the width direction of the disposable auxiliary pad, and the outer side edge 30 of the fastening member is within 10 mm or more from the side edge 22 of the disposable auxiliary pad. It is preferable that it is located in the direction. By disposing the fastening member away from the side edge 22 in the width direction of the disposable auxiliary pad, the disposable auxiliary pad 1 is placed in the diaper at the interval 27 from the side edge 22 in the disposable auxiliary pad 1 to the fastening member 10. It is in a free state without being joined to the body. The operator can also pinch the gap 27 with his / her finger and can be used for position adjustment. Moreover, since the part of this space | interval 27 does not follow the motion of a diaper main body, it does not bend or bend | fold according to a relationship with a diaper main body, and can prevent the leakage of excrement resulting from those bending / folding. .

  The dimension of the distance 27 in the width direction 19 is preferably 10 mm or more, more preferably 15 mm or more, preferably 30 mm or less, and more preferably 25 mm or less. If the size exceeds 30 mm, there is too much freedom, and the auxiliary pad alone can be easily bent. Also, if the dimension is less than 10 mm, it is difficult for the operator to grip and difficult to work.

  The front fastening member 10 and the rear fastening member 11 are preferably provided with a gap 28 between the left and right fastening members. Since there is this space | interval, it can work by putting a hand between the right-and-left fastening member, and it becomes easy to adjust a position when attaching to a diaper main body. By fitting the disposable auxiliary pad at an appropriate position according to the wearer's body shape and posture, it can be surely fitted, and as a result, leakage can be reduced.

  The interval 28 between the left and right fastening members is preferably 50 mm to 90 mm. When the interval is smaller than 50 mm, it is difficult for the wearer's hands and fingers to enter. Further, when the interval is larger than 90 mm, the fastening of the disposable auxiliary pad becomes unstable.

  Referring to FIGS. 1 and 3, the width of the top sheet 2 is set to be narrower than the width of the disposable auxiliary pad 1, and the lower surfaces of both side edges of the top sheet 2 are slightly outside the folded end 9 of the back sheet 3.

The lower surface of the portion slightly outside of the first folded edge 36 of the side sheet 5 is bonded to the upper surface of the top sheet 2 by the second bonding portion 33. The other lower surface of the side sheet 5 is also joined to the upper surface of the top sheet 2 and the upper surface of the folded back sheet 3 (not shown). The portion of the side sheet 5 that is inward of the second joint portion 33 is an upright portion 6 that stands up toward the wearer's skin by the contraction force of the elastic member 7 attached in an extended state.

  In the example of FIGS. 1 and 3, the upright portion 6 is folded outward at the first folded edge 36, then folded inward at the second folded edge 34, and then the third folded edge. The edge 35 is folded back inward so as to cover the elastic member 7. The elastic member 7 is attached in an extended state inside the third folded edge 35. The folded upright part 6 is fixed in a folded state in the vicinity of the edge in the length direction 18 of the disposable auxiliary pad 1. Since the standing part 6 between the fixed parts is not fixed, it stands up toward the wearer's skin by the contraction force of the elastic member 7. Since the standing part 6 stands mainly in the crotch part of the wearer, it is possible to prevent side leakage of excrement such as urine in the crotch part.

  For the elastic member 7, a stretchable material such as polyurethane thread or natural rubber sheet is used. For joining the materials, joining with a hot melt adhesive or hot melt joining is used.

The distance 43 between the side edge 30 of the fastening member and the side edge 24 of the absorber 4 is preferably 10 mm or more, more preferably 15 mm or more, and preferably 30 mm or less. If the size exceeds 30 mm, there is too much freedom, and the auxiliary pad alone tends to bend. Also, if the dimension is less than 10 mm, it is difficult for the operator to grip and difficult to work.

  In both the first embodiment and the second embodiment, the side seat 5 is used to provide an upright portion 6 for preventing side leakage. As a modification, the entire surface may be covered only with the top sheet 2 without using the side sheet 5. Other modifications may be made within the scope permitted by the gist of the present invention.

  FIG. 7 shows another preferred embodiment (third embodiment 201) of the disposable auxiliary pad of the present invention. FIG. 7 is a back view of the disposable auxiliary pad as seen from the back side. In the disposable auxiliary pad 201, the attachment position of the fastening member is changed.

The absorbent main body 57 includes an absorbent body 76, a top sheet 58 made of a non-embossed nonwoven material provided on the inner surface side of the absorbent body 76, and a liquid-impermeable back provided on the outer surface side of the absorbent body 76. And a sheet 75. As shown in FIG. 10, a side sheet 59 made of an embossed nonwoven material is joined to the upper part of both side edges in the width direction of the top sheet 58 made of a non-embossed nonwoven material. The side seat 59 forms a rising flap that stands up toward the wearer's skin by the contraction force of the elastic member 84 attached in a stretched state in the length direction, and serves as a barrier that prevents lateral leakage of urine and the like. . The top sheet material includes a liquid-permeable non-embossed stop sheet 58 and a liquid-impermeable embossed side sheet 59.

  FIG. 11 is a schematic cross-sectional view illustrating another preferred embodiment of the diaper body. A liquid-impervious embossed side sheet is joined to upper portions of both side edges of the liquid-permeable non-embossed stop sheet. The side sheets inward from the joint point form a rising flap that rises toward the wearer's skin. The side sheet outside the joining point extends outward from the side edge of the absorber 76 and is joined to the back sheet 73. The surface sheet material includes a liquid-permeable non-embossed stop sheet 58 and a liquid-impermeable embossed side sheet 59.

  Hereinafter, the aspect which attaches and uses the disposable auxiliary pad of this invention to a diaper main body is demonstrated still in detail, referring FIGS. As shown in FIG. 12, the disposable auxiliary pad 1 is folded in two by a two-fold portion 37. In the state folded in two, as shown in FIG. 13, it overlaps and joins to the inner surfaces 41 and 42 of the diaper main body 38. As shown in FIG.

  In FIG. 14, the cross-sectional schematic diagram of the scene which superimposes the disposable auxiliary pad 1 on the diaper main body 55 is shown. The fastening members 10 and 11 provided on the back surface of the back sheet 3 of the disposable auxiliary pad 1 engage with a top sheet 58 made of a non-embossed nonwoven material. And since the fastening members 10 and 11 are located between the left and right side sheets 59 comprised with the embossed nonwoven material, they do not engage with the nonwoven fabric side sheets 59 basically. Even if it is slightly deviated and comes into contact with the nonwoven fabric side sheet, since the side sheet is embossed, the fastening member having the hook member is not easily engaged. According to the present invention, it is possible to prevent the fastening member from being erroneously engaged with the side seat as described above.

  If the fastening members 10 and 11 of the disposable auxiliary pad are accidentally engaged with the non-woven side sheet 59, the non-woven side sheet may fall down or become wrinkled and lose its function as a barrier. There is. In the present invention, there is no such concern, and the non-woven side sheets can be overlapped without impairing the barrier function.

  Furthermore, since the top sheet nonwoven fabric 58 is made of a non-embossed nonwoven fabric material, the hook member can be easily engaged, and displacement of the superimposed disposable auxiliary pads can be prevented. The fastening members 10 and 11 are preferably provided within a width of 100 mm so as to be easily engaged with the top nonwoven fabric 58.

  In FIG. 8, a disposable auxiliary pad virtual line 80 indicated by a two-dot chain line is a position where typical disposable auxiliary pads are overlapped. In particular, the fastening member virtual line 81 is on the nonwoven fabric top sheet 58 and is positioned so as not to overlap the nonwoven fabric side sheet 59. Furthermore, the second disposable auxiliary pad virtual line 82 and the second fastening member virtual line 83 show the case where the disposable auxiliary pad is displaced in the length direction. If the absorbent main body 57 deviates from a region where the absorbent main body 57 exists, such as 82 and 83, the fastening member 83 may not be engaged. Therefore, in the diaper main body 55 of the present invention, the front end pressing sheet 77 and the rear end pressing sheet 78 so as to cover the lengthwise ends of the absorbent main body 57 at the front abdomen 60 and the rear portion 62 of the inner surface of the inner sheet 74. Further, the fastening member can be engaged by using a non-woven material that is not embossed on the end pressing sheets.

  Even when the disposable auxiliary pad is displaced in the length direction by the end pressing sheet, the fastening member can be easily engaged, and the suitability of the disposable auxiliary pad and the disposable diaper is not lowered.

Non-embossed non-woven materials used for the non-woven top sheet 58 and the end presser sheets 77 and 78 include heat-embossed bonding for bonding between fibers such as air-through non-woven fabric, spunlace non-woven fabric, needle punched non-woven fabric, and chemical bonded non-woven fabric. It is preferable to use a non-woven fabric material that does not use. Most preferred is an air-through nonwoven fabric having a basis weight of 10 to 40 g / m ² .

Moreover, as the embossed nonwoven material used as the side sheet 59, it is preferable to use a nonwoven material that uses hot emboss bonding for bonding between fibers, such as spunbond nonwoven fabric, SMS nonwoven fabric, and point bond nonwoven fabric. Most preferred is a spunbond nonwoven fabric or SMS nonwoven fabric having a basis weight of 10 to 30 g / m ² . These spunbond nonwoven fabrics or SMS nonwoven fabrics can also be preferably used for the outer sheet 73 and the inner sheet 74.
