Description

— \ — Disposal diaper having crotch streching unit Full Description Background The present invention relates to a disposable diaper . It has a front waistline region; a back waistline region “and a crotch region ©; inside it a pair of open units for the legs are formed; into which a single-use diaper is supplied With an absorbent direction along the branching area and extending to the front waistline and the back waistline area.In such a single-use diaper, Sie, several fittings are provided to obtain complete comfort during wearing while preventing the leakage of body waste.For example; In the direction of Ve is a longitudinal product; the absorber is divided into three parts; outside of the absorber in a product in the widthwise direction ; a flexible member is placed in an extended state (eg; leg gather Jaf or static assembly ( solid gather along the longitudinal product direction le) x Bell JE Unexamined Japanese Patent Application Bulletin No. (Y ..-1 0 . (idl (a) this one-use pad She; the absorbent Lidl) is divided into three parts 1 sticky in contact with each other while the spacers with tight adjacent absorbents; thus the single-use diaper Sy corresponds With the wearer, thus narrowing the space between the single-use she diaper and the wearer at the time of putting on the he single-use diaper. One She is used such that the surface in contact with the skin is directed to the Jalal (eg Ye. Unexamined Japanese Patent Application Publication No. (Y ce 0—YYaY eT .

b Japanese Patent No. 7001-79717 relates to an absorbent class having a central body (pe provided in a central en in a transverse direction for the class ald) wherein the flexible central body is LB for extension in a longitudinal direction of the absorbent class; It also relates to a method for manufacturing an absorbent class. The problem is that the Be disposable nappy is a panty type; The apparent 0 product midline is consistent with the fold line. So if the nappy used fhe one 01 is folded in two sectors; The pla of the posterior side end of the back waist region Ye and the front end height of the front waist region 01 are not made equal. International Patent No. 11871164/7007 relates to an article that is worn and a method for its manufacture; Where the aforementioned document provides a cal class that is characterized by its inclusion of a waist area formed in a circular shape that can surround a continuous image of a wearer’s waist and use one of the openings as a waist opening and a branching area connected to the waist area through an opening on the opposite side of the waist opening so that the branching area and the waist area are determined by a pair of two leg openings for the wearer to put his legs through individually; Where the branching area is formed by bending inwards, where the branching area is made to shrink in a direction in which the opposite internal surfaces (Glas) in the waist area approach each other. The problem is that the shrunken region 1 is not supplied on the front side from the midline of the apparent product. So if the wearer wears a Bre single-use nappy; The shrinkage area is not suitable for the wearer's body characteristic. Japanese Patent No. 700081721515 relates to a single use Bp pants type diaper. More specifically; The present invention relates to a diaper using Hal, one of the type of pants, in which an opening is formed around the waist and a pair of openings for the legs, which are formed as a type in the form of pants, and from which the main absorbent body can be separated. The problem is that the flexible member does not overlap the bend line. The space is not confined between the fhe single use nappy 01 and the wearer. The general description of the invention in the She single-use diaper is as above; The entire diaper, which is used one he in the product, is shrunk in the transverse direction due to the force of contraction of an elastic LEAR member

_ _ member such as a jaf assembly or static assembly; The single-use Spe pad is in close contact with the wearer. Tag for that; The front waistline and back waistline of the diaper using one SW are easily tightened in a bifurcation direction. specifically; After the disposable diaper absorbs the body's waste; The front waistline and the back waistline of the diaper using SW one go in the bifurcation direction; It easily shows an unrequired gl between the wearer's leg opening and the diaper using one Se. lad sealed Ge single-use diapers are sealed in a package in their folded and compressed state; A predetermined pressure is applied to the disposable diaper. Moreover; The She single-use diaper is folded so that the surface of contact with the skin is directed 0 inward. So in the She single-use diaper; A convex fold is formed to be directed in the direction where the diaper is diverged from the wearer. Dla for this crease; A space is created between the disposable diaper and the wearer; The space that appears between the $e one-use diaper and the wearer increases when the $e-one diaper is put on. Although the force of contraction of the elastic member has also been increased to prevent the gap between the Spe One-Piece Diaper and the Das Drape Wearer; Vo Laff The back waistline and the front waistline area of the diaper using He is moved one in the direction of bifurcation. Accordingly; The present invention has been introduced to solve the previous problem; The purpose of the present invention is to provide a single use Spe diaper that can prevent shifting of the front waistline and back waistline area of a single use Be diaper in a bifurcation direction while preventing the void that appears between the 0 - use she diaper And the wearer at the time of putting on the single-use §he diaper even in the case that the single-use §Be diaper in its folded state is sealed in a package. Spe single-use diaper according to its first side: front waistline area; back waistline; a bifurcation area between the anterior waistline and the posterior waistline; Where one $5 diaper has: Product longitudinal direction (YO) directed from the front waistline to the back waistline; and product in direction LEAR].

Qo _ _ transverse perpendicular to the direction of the longitudinal product; A disposable diaper includes: an absorbent oriented along the fork area and extending at least one of the anterior waistline and posterior waistline areas; And a crotch stretching unit is formed at a position that overlaps with the absorbent in the branching area and is flexible 3, where a branching bag extending to the direction is formed along a true midline of a product passing through the middle of the diaper that uses one She in the direction of the product longitudinal and stretch along the product in the transverse direction; In Ala Extended Single Spe Diaper; And it overlaps in the branching area with two fold lines that extend along the product in the transverse direction for the purpose of overlapping the front waistline area and the back waistline area with each other in a normal condition 0 for the diaper that uses Goals Be where; In the case when the single Ho diaper is in a stretched state; jag is a true midline forked passing through the midpoint of the fork extending in the longitudinal direction of the product and extending along the product in the transverse direction in an anterior aspect more than the true midline produced; Whereas the two fold lines are provided on a posterior side in a manner greater than the true center line produced; in the longitudinal direction of the product.
