  However, in the absorbent article described in Patent Document 1, the cross-sectional shape in the width direction of the three-dimensional gather has a substantially Ω shape in which the maximum width L3 in the three-dimensional shape of the gather is larger than the distance L2 between the joining ends. The hollow three-dimensional shape portion is not necessarily formed at a sufficient height, and there is a possibility that the close contact with the body is lost and a side leak occurs.

  Moreover, in the absorbent article of the said patent document 2, although the joint part of an elastic sheet is made to meander, the high wall part which heightened the height of the hollow loop-shaped leak-proof wall partially was formed. In addition, there is a possibility that the high wall portion may fall inward at the time of wearing. In this case, the upper surface of the absorbent body is covered with the stretchable sheet, so that the body fluid absorbing function may be lowered. Also in the absorbent article described in Patent Literature 1, particularly when the distance between the joining ends on the both ends in the longitudinal direction of the absorbent article is formed larger than the distance between the joining ends in the center in the longitudinal direction of the absorbent article. Can cause similar problems.

  Therefore, the main problem of the present invention is that in an absorbent article in which a hollow loop-shaped three-dimensional gather is formed along the longitudinal direction on both sides on the use surface side, a sufficient height that can be in close contact with the body can be secured, An object of the present invention is to provide an absorbent article in which gathers are less likely to fall inward and have a high leakage prevention effect.

Therefore, in the standing portion of the loop-shaped three-dimensional gather, the outer inclined surface is widened to form a highly standing hollow portion. Therefore, a sufficient height that can be in close contact with the body can be secured, and the leakage prevention effect is enhanced by fitting around the leg.

  Further, in the standing portion of the loop-shaped three-dimensional gather, the length from the base end portion to the top portion of the outer inclined surface is shorter than the length from the base end portion to the top portion of the inner inclined surface, and the width of the absorbent article Since the angle of inclination of the inner inclined surface with respect to the direction line is formed at 45 ° or less, the loop-shaped three-dimensional gathers generally fall outward so that the outer inclined surface bulges outward when the absorbent article is mounted. It deforms as follows. Therefore, a situation in which the looped three-dimensional gathers fall inward and covers the body fluid absorbing surface can be prevented, so that the body fluid absorbing function is not lowered and the leakage preventing effect is enhanced.

Furthermore, in the present invention, since the elastic force of the elastic elastic member arranged on the outer inclined surface is set to be larger than the elastic force of the elastic elastic member arranged on the inner inclined surface, The outer inclined surface folded inside the loop-shaped three-dimensional gather at the portion can be sufficiently raised at the standing portion.

As the present invention according to claim 2, the loop-shaped three-dimensional gather is a first folded portion in which a sheet extending from the outer side in the width direction to the inner side in the absorbent article is folded from the surface to the standing side in the protruding direction at the inner position.

Examples of the pulp include chemical fibers obtained from wood, cellulose fibers such as dissolving pulp, and artificial cellulose fibers such as rayon and acetate. It is preferably used in terms of price. When the crepe paper 5 surrounding the absorbent body 4 is provided as in this example, the crepe paper 5 is interposed between the liquid-permeable surface sheet 3 and the absorbent body 4 as a result. The crepe paper 5 which is excellent in diffusing body fluids quickly prevents reversal of menstrual blood and the like.

  On the surface of the sanitary napkin 1, a pressing groove 8 can be formed in an appropriate shape. In the example shown in FIG. 1, a pressing groove 8 that is elongated in the longitudinal direction of the napkin 1 and closes in the circumferential direction is formed.

In the illustrated example, the width dimension of the liquid-permeable surface sheet 3 is slightly longer than the width of the absorbent body 4 as shown in the cross-sectional view of FIG. The three-dimensional gather BS, BS is formed of a non-gathering nonwoven fabric 6 different from the liquid-permeable top sheet 3, and the outside of the three-dimensional gather BS, BS is outside the liquid-impervious back sheet 2. An extending gather forming nonwoven fabric 6 is laminated. These gather forming nonwoven fabrics 6 are made of nonwoven fabric materials that have been subjected to appropriate water-repellent treatment or hydrophilic treatment depending on the purpose of preventing menstrual blood, vaginal discharge or the like from penetrating or enhancing the feeling of touch. It is configured. The nonwoven fabric 6 may be made of natural fibers, synthetic fibers, regenerated fibers, or the like and formed by an appropriate processing method. Preferably, the nonwoven fabric 6 has a feeling of creaking and prevents stuffiness. In addition, it is preferable to use a non-woven fabric with reduced basis weight and air permeability. Specifically, it is desirable to use a nonwoven fabric prepared with a basis weight of 13 to 23 g / m ² , and silicon-based, paraffin-based, alkylchromic chloride-based water repellents, etc. to reliably prevent the passage of body fluids. A water repellent nonwoven fabric coated with is preferably used.

As shown in FIG. 2, the gather forming nonwoven fabric 6 is bonded to the outer edge of the liquid-impermeable back sheet 2 with an adhesive such as hot melt, and the gather forming nonwoven fabric 6 is impermeable to the gather forming nonwoven fabric 6. The laminated sheet portion with the liquid-permeable back sheet 2 forms a pair of left and right wing-shaped flaps W, W at the absorbent body side position substantially corresponding to the body fluid discharge portion, and the second wing-shaped flap at the buttocks side position from this. W _B, to form a _{W B.} These wing-shaped flaps W, W and second wing-shaped flaps W _B, W, respectively on the outer surface side adhesive layer 10 ... of _B, 11 ... comprises a, when worn against shorts, line folding the wing-shaped flaps W, W It is folded back to the opposite side at the RL position and wrapped around the crotch portion of the shorts to be fastened.

  In the gather forming nonwoven fabric 6, the widthwise inner portion of the napkin 1 is folded back twice, and the double sheet portion is folded back to the upright side protruding from the surface of the sanitary napkin 1 to form a hollow looped three-dimensional gather BS Is forming. At a predetermined position inside the double sheet, a plurality of elastic elastic members 21..., 22.

Hereinafter, the loop-shaped three-dimensional gather BS will be described in detail.
[About loop-shaped solid gather BS]
The loop-shaped three-dimensional gather BS is joined to the use surface side of the napkin 1 by an outer joint portion 30 and an inner joint portion 31 formed along the longitudinal direction at least in the width direction outer side and the inner side of the napkin 1, respectively. The outer inclined surface 32 has an upright base end in the vicinity of the outer joint portion 30 and the inner inclined surface 33 has an upright base end in the vicinity of the inner joint portion 31. The outer inclined surface 32 and the inner inclined surface 33 are provided. By having a structure with the intersection point with the apex P, the cross section is a hollow loop shape. The outer joint portion 30 and the inner joint portion 31 are formed in a certain range in the napkin width direction from the standing base ends of the outer inclined surface 32 and the inner inclined surface 33 even if the width direction range is not clearly defined. What is necessary is just the part of the joined part. The outer joint portion 30 and the inner joint portion 31 are formed substantially linearly along the napkin longitudinal direction.

  Specifically, in the example shown in FIG. 4, the loop-shaped three-dimensional gather BS has a double sheet portion of the gather-forming nonwoven fabric 6 extending from the outer side in the width direction of the napkin 1 to the inner side and protrudes from the surface at the inner position. A first folded portion 34 that is folded back on the upright side of the direction, and a second folded portion 35 that is folded back to the back sheet 2 side on the width direction outside of the napkin 1 at the standing side position that is continuous with the first folded portion 34. And a third folded portion 36 that is folded back inward in the width direction at the use surface side position of the napkin 1 that is continuous with the second folded portion 35, and the first folded surface 37, the second folded surface 34 in order from the first folded portion 34. A folded surface 38 and a third folded surface 39 are formed. That is, the first folded surface 37 is an inner inclined surface 33, the second folded surface 38 is an outer inclined surface 32, and is joined to the liquid-permeable surface sheet 3 in the vicinity of the outside of the first folded portion 34. An inner joint portion 31 is formed, and an outer joint portion 30 to be joined to the gather forming nonwoven fabric 6 is formed on the third folded surface 39. At least one of the double sheets on the outer side in the width direction from the first folded portion 34, in the illustrated example, a loop-shaped inner sheet extends to the side edge of the sanitary napkin 1.

  The loop-shaped three-dimensional gather BS is not limited to the illustrated example, and the gather-forming non-woven fabric 6 extending from the width direction outer side to the inner direction of the napkin 1 is folded back to the standing side at the outer position, and then raised. A hollow loop-shaped three-dimensional gather BS may be formed by folding the napkin 1 in the width direction on the side position to the back sheet 2 side.

  In the loop-shaped three-dimensional gather BS, the outer inclined surface 32 and the inner inclined surface 33 do not have to be formed linearly from the standing base end portion to the top portion P in the cross-sectional view shown in FIG. Thus, the intermediate portion may have a refracting portion, or may be curved in a curved shape from the standing base end portion to the top portion P. In addition, when the whole is formed in a curvilinear shape, a point having the maximum standing height from the napkin surface is defined as the apex P, and the outer inclined surface 32 and the inner inclined surface 33 are respectively set on the outer side or the inner side in the width direction as a boundary. And

  As shown in FIG. 3, at both ends in the longitudinal direction of the napkin 1, the outer inclined surface 32 is laminated so as to be folded inside the loop-shaped solid gather BS, thereby eliminating the standing of the loop-shaped solid gather BS. It is considered as a non-standing part. In the example shown in FIG. 3, the outer inclined surface 32 is folded twice with the center in the height direction on the inside, laminated inside the loop-shaped three-dimensional gather BS, and the folded portions are bonded to each other by hot melt or the like. It joins by the junction part 40 by an agent, and the inside of the inner side inclined surface 33 is joined by the junction part 41 by an adhesive agent similarly. The outer inclined surface 32 may be folded not only in a double manner as in the illustrated example but also in a plurality of bellows shapes.

  On the other hand, in the standing portion of the loop-shaped three-dimensional gather BS, the length L1 from the base end portion of the outer inclined surface 32 to the top portion P is shorter than the length L2 from the base end portion of the inner inclined surface 33 to the top portion P. The inclination angle α of the inner inclined surface 33 with respect to the width direction line of the sanitary napkin 1 is set to 45 ° or less, preferably 30 ° to 45 °.

On the outer inclined surface 32, a plurality of elastic elastic members 22 in the illustrated example, in which appropriate positions in both ends or in the longitudinal direction are fixed at an intermediate portion in the height direction, are arranged in an expanded state. , looped standing gathers and the top P of the BS in the height direction intermediate portion of the inner inclined surface 33, the plural rows of appropriate positions of both ends or longitudinal direction is fixed, the elastic expansion and contraction of Article 5 in the illustrated example member 21 Are arranged in an extended state. Thereby, the intermediate part except the non-erection part of the longitudinal direction both ends of the sanitary napkin 1 is made into the standing part of the loop-shaped solid gather BS which stands on the surface side.

  With the above structure, the loop-shaped three-dimensional gather BS is laminated in such a manner that the outer inclined surface is folded inside the loop-shaped three-dimensional gather BS at the non-standing portions at both longitudinal ends of the sanitary napkin 1. In the standing portion of the three-dimensional gather BS, the folded portion stands up on the surface side so that the three-dimensional gather is formed high, so that the height necessary to be in close contact with the body can be ensured.

  Further, since the width L1 of the outer inclined surface 32 is formed shorter than the width L2 of the inner inclined surface 33, and the inclination angle α of the inner inclined surface 33 is regulated within 45 °, as shown in FIG. When the napkin 1 is worn, the looped three-dimensional gather BS is brought into close contact with the body so as to fall outside with a fall width A, so that it is difficult to fall to the body fluid absorption surface side, and the body fluid absorption function is reduced. Nothing will happen.

  On the contrary, as shown in FIG. 6, the width L1 of the outer inclined surface 32 is formed longer than the width L2 of the inner inclined surface 33, and the inclination angle α of the inner inclined surface 33 exceeds 45 °. In the case where the three-dimensional gather BS is attached, it is easy to fall inward, and an inward fall width B is formed. Therefore, the absorption surface of the body fluid is narrowed, and the absorption function of the body fluid is reduced. Absent.

  Furthermore, since the loop-shaped three-dimensional gather BS is in a loop shape, the loop-shaped three-dimensional gather BS closely adheres around the legs, and the leakage prevention effect is enhanced. Moreover, since the joint parts 30 and 31 of the loop-shaped three-dimensional gather BS are provided in a straight line along the longitudinal direction of the sanitary napkin 1, the manufacture of the napkin 1 is simplified.

  The plurality of elastic elastic members 21, 22,... Arranged in the three-dimensional gather BS may be arranged in a state where all members having the same tension are extended with the same tensile force, but are inclined outward. The elastic elastic members 22 arranged on the surface 32 are preferably set to have a higher elastic force than the elastic elastic members 21 arranged on the inner inclined surface 33. As a result, the outer inclined surfaces 32 stacked in the folded state at the non-stand-up portions at both ends in the longitudinal direction of the sanitary napkin 1 can easily stand up at the stand-up portion, and the hollow loop-shaped three-dimensional gather BS is raised higher. Will be able to. In order to set the expansion / contraction force high, a thicker one can be used as the elastic expansion / contraction member 22, or the tension at the time of fixation can be increased to increase the tension.

  In the three-dimensional gather BS, it is preferable that the maximum width L3 in the width direction of the sanitary napkin 1 is substantially equal to the joint portion width L4 from the outer joint portion 30 to the inner joint portion 31. That is, the outer inclined surface 32 and the inner inclined surface 33 are formed so as to stand on the use surface side with the joint end portions of the outer joint portion 30 and the inner joint portion 31 as a base point. For this reason, a loop-shaped three-dimensional gather BS having a high protruding height can be formed.

  In the illustrated example, the sanitary napkin 1 is formed so that the cross-sectional shape with respect to the cross-section in the width direction is a substantially triangular shape, but it may be formed in a trapezoidal shape or a half-oval shape.
