Field of the Invention The present invention applies a pulling force by a single fastening means provided on the inclined side edges of a pair of ears arranged along the longitudinal ends of an absorbent body in the waist circumference direction and The present invention relates to a disposable diaper that is effectively dispersed in the direction around the legs to prevent liquid leakage around the legs and waist of the wearer and to provide comfort to the wearer.

手段を備えて構成されている。2. Description of the Related Art A commonly-used disposable diaper has an absorbent body having an absorbent core between a top sheet and a back sheet and arranged so as to cover a wearer's crotch, and a longitudinal end of the absorbent body. A pair of ears arranged along the waist around the waist of the disposable diaper, and fastening means provided at the side edges of the ears.

が要求されている。In use of the above disposable diaper, the body of the diaper is attached to the wearer by a usual method, and the fastening means provided on the ears is fixed around the waist of the disposable diaper on the side opposite to the fastening means. It is designed to be attached to the wearer. In a disposable diaper, when it is worn on a wearer, it fits around both the waist and legs of the wearer, and when worn, it is particularly required to prevent liquid leakage from the legs and waist.

という難点があった。However, in a disposable diaper of the type in which one fastening means is provided on the side edge of the ear, when the diaper body is worn on the wearer, the pulling force of the fastening means is applied to the waist and legs of the wearer. It was difficult to focus effectively on both.
In other words, if the disposable diaper is attached so that it fits snugly around the wearer's waist, a gap may be created around the wearer's leg, and liquid may leak from the leg during use. On the other hand, if it is attached so as to fit around the legs of the wearer, a gap is created around the waist of the wearer, which makes it difficult to fit exactly around the waist of the wearer.

付け位置について言及していない。However, when these fastening means are attached to the ears of a disposable diaper, the pulling force thereof can be effectively and directly concentrated around the waist and legs. It does not mention the mounting position. Further, it does not mention the mounting position of the fastening means in which the proportion of the pulling force by the fastening means distributed around the waist and around the legs is intentionally changed.

予め設定したような腰周りと脚周りに配分できない。Further, one fastening means is attached to the ear portion of the disposable diaper while being inclined toward the back side end direction with respect to the lateral axis of the disposable diaper body, and the pulling force can be effectively applied to the waist and leg directions. A disposable diaper that is dispersed in the direction is disclosed, for example, in Japanese Utility Model Laid-Open No. 59-73305, but this technical means is such that the fastening means is provided in the ear portion of the disposable diaper on the lateral axis of the main body of the disposable diaper. In contrast to this, even if it is attached so as to be inclined toward the back end, the user is not required to pull the fastening means because the side edges of the ears are perpendicular to the lateral axis of the disposable diaper body. In order to pull the fastening means in the direction orthogonal to the side edge of the ear,
Even if one fastening means is attached to the side edge of the ear portion of the disposable diaper at an angle, the pulling force of one fastening means cannot be distributed around the waist and legs as preset.

1, a stress relaxation area 20 is formed which can be stretched by a small tensile force. Since the peripheral portion of the stress relaxation area 20 of the sheet 21 forming the ear portion 6 is left unprocessed, it does not expand even if a tensile force is applied, or it expands more than the stress relaxation area 20. This is a difficult area. In addition, the stress relaxation area 20 formed in this way

As shown in FIG. 13, the fastening means 7 is attached to the inclined side edge 6 of the ear portion 6.
The pulling force D when pulled in a direction orthogonal to a is divided into two directions, a pulling force D1 in the waistline direction and a pulling force D2 in the legline direction. That is, since the peripheral portion does not expand unless a higher tensile force is applied than the stress relaxation area 20, most of the tensile force by the fastening means 7 is transmitted to the peripheral portion as the tensile forces D1 and D2. , Acts directly on the regions X and Z on the absorber side. However, even if the tensile force of the fastening means 7 acts on the stress relaxation area 20,
Since the stress relaxation area 20 can be expanded by a relatively small tensile force, and the peripheral portion of the stress relaxation area 20 is not expanded, the stress relaxation area 20 can be expanded to the limit as shown in FIG. Absent. Therefore, the stress relieving area 20 is provided with the fastening means 7 due to its extensibility.
It absorbs the tensile force due to and does not directly transmit the tensile force to the region Y on the absorber side. In this way, the fastening means 7
The pulling force D is divided into two component forces, a pulling force D1 in the waistline direction and a pulling force D2 in the legline direction. These pulling forces D1 and D2 act directly as a force for tightening the disposable diaper around the waist and a force for tightening the disposable diaper around the legs, respectively.

By making the overlapping ratio of the first inclined side edge region a and the second inclined side edge region b different, the distribution of the tensile force to each involved area can be made different. That is, when the ear attachment position of the fastening means 7 is such that the attachment area R of the fastening means 7 completely overlaps the first inclined side edge area a and only partially overlaps the second inclined side edge area b. , The first inclined side edge region a
Since the ratio of overlapping with the
A larger component force is distributed toward 0. Contrary to this, the ear attachment position of the fastening means 7 is such that the attachment area R of the fastening means 7 completely overlaps the second inclined side edge area b and only partially overlaps the first inclined side edge area a. In such a case, since the ratio of overlapping with the second inclined side edge region b is larger, a larger component force is distributed to the leg circumference component force participation area 41. In any of the above cases, it suffices that the overlapping ratios are different, and the attachment area R of the fastening means 7 is not always necessary.
Need not be included in one inclined side edge region.

In this example, a line L1 extending from the point P in contact with the stress relaxation area 20 and a line L2 extending from the point Q in contact with the stress relaxation area 20 reach the inclined side edge 6a of the ear 6 without intersecting in the middle. . As shown in FIG. 21, the first inclined side edge region a in the inclined side edge 6a is a region closer to the edge 1a than the point A, and the second side edge region b is greater than the point B in the lateral centerline H.
-H 'side area. Therefore, each inclined side edge region a,
A region 33 that does not participate in the waist circumference component force participation area 40 and the leg circumference direction component force participation area 41 is formed between b. In order to concentrate the pulling force of the fastening means 7 directly on the waist and the gyrus, the attachment area R of the fastening means 7 is arranged so that the attachment area R of the fastening means 7 crosses the area 33 and the first inclined side edge area a and the second inclined side edge area. It must be placed in a position that includes b. So in this case, too,
Since the attachment region R of the fastening means 7 overlaps a part of each of the inclined side edge regions a and b, the tensile force of the fastening means can be directly concentrated on a required portion.

Even if it travels through, it will be cut at the lower edge 6c of the ear portion 6. In this case, the first inclined side edge region a is an upper portion in the arrow direction from the point A of the inclined side edge 6a of the ear portion 6, and the second inclined side edge region b.
