Description

  The present invention relates to an absorbent article, and more particularly, to an absorbent article for promoting standing of a three-dimensional gather.

  Conventionally, disposable diapers (hereinafter also simply referred to as “diapers”) provided with a pair of three-dimensional gathers for effectively blocking discharged body fluid (hereinafter also simply referred to as “liquid”) and not leaking to the outside, etc. Absorbent articles are widely known.

  In order to effectively dam the liquid, it is desirable that the standing of the three-dimensional gather be maintained in the wearing state, but there are cases where the three-dimensional gather is knocked down or crushed depending on the posture and movement of the wearer when wearing it. .

  Thus, in a deployable diaper, Patent Document 1 discloses a configuration in which a three-dimensional gather is pulled up toward the outside in the width direction of the diaper by a tension member when the diaper is worn. In the diaper of Patent Document 1, one end of the tension member is bonded to the side wall of the three-dimensional gather, and the other end is bonded to the inner surface of the fastening tape. Then, by fastening the fastening tape to the fastening area of the front body of the diaper, the three-dimensional gather is pulled up by the tension member and stands up.

Japanese Patent No. 5238106

  However, in the diaper described in Patent Document 1, the force for pulling the three-dimensional gathers acts only in the width direction with respect to the part to which the tensile member is bonded, and the range for raising the three-dimensional gathers is around the bonded part. Therefore, there is a possibility that the standing state of the three-dimensional gather becomes insufficient, and the liquid cannot be effectively dammed up by the three-dimensional gather.

  An object of the present invention is to provide an absorbent article for raising a three-dimensional gather in a desired range.

  An absorbent article according to the present invention includes a liquid-impermeable back sheet, a liquid-permeable top sheet, an absorbent body arranged between the back sheet and the top sheet, and both side edges of the absorbent body. An absorbent article comprising a pair of standing three-dimensional gathers, wherein elastic members are arranged in a stretched state along the longitudinal direction of the three-dimensional gathers at the side edges that are free ends in the width direction of the three-dimensional gathers, At least one longitudinal end region of the three-dimensional gather is not bonded to the surface of the absorbent article.

  According to the present invention, since the three-dimensional gather can be effectively erected, it is possible to effectively prevent liquid leakage.
