Disposable napkin

Abstract

The invention discloses a napkin (1), which is characterized by the following: a couple of leg wing (5, 5) with elastic component (51) is set on two lateral parts of absorbent (4) along longitude direction; the back sheet (3) is allocated between two ends along napkin length direction; the component (51) of wing part (5) is allocated near external end of wing (5) breadth direction, which doesn't form overlapping structure; a couple of extension part (7, 7) along breadth direction is allocated on two lateral parts of back part B, whose extension region lies out of allocating direction of wing (5) to approach one lateral position of sheet (3) based on positive sheet (2) awes datum direction; the extension part (7) connects the sheet (3); the belt (13) is projected toward external end breadth direction of extension part (7); the center part of non-contact side with component (51) in the wing (5) is covered.

Description

technical field [0001] The present invention relates to disposable diapers, and more particularly to disposable diapers having leg flaps. Background technique [0002] Conventionally, disposable diapers having leg wings are widely known. In this diaper, a pair of leg flaps are disposed along both sides in the longitudinal direction of the diaper, and folds (folds) are formed by leg gathers on the outside of the leg flaps. [0003] With this disposable diaper, when the diaper is worn for a baby, the folds of the leg gathers in the leg wings of the diaper will enter into the inside of the diaper. Occurs when urine leaks from the wing of the leg. Therefore, when a parent or the like wears a diaper for a baby, it is necessary to pull out the folds of the leg gathers of the legs to the outside of the diaper and adjust them, which causes trouble when putting on the diaper. [0004] In addition, there is known a disposable diaper in which an elastic member forming a leg gather i...

AI Technical Summary

Problems solved by technology

[0008] However, due to the movement of the diaper wearer, the leg gathers of the diaper tend to move in the crotch and sink into the groin, and tend to move toward the buttocks in the buttocks, so new problems arise.

As a result, the fit of the diaper decreases, and it also causes leakage

[0009] The reason is as follows: in the case where the leg flaps have folds of the leg gathers, the folds will form resistance to prevent the movement of the leg flaps, but in the case of no or almost no folds in the leg flaps, due to the use of the diaper The flaps of the legs become easy to move due to the movement of the person

[0010] In addition, in the state of use of the diaper described in Japanese Patent Application Publication No. 8-508657, since the non-skin-contacting side of the leg flap is not covered by the leak-proof sheet in the central part of the diaper's longitudinal direction, urine leakage may occur. Fluid leaks from the wings of the legs
