Problems solved by technology

[0003] The disadvantage of having elastic stretchable members on the edge of the opening and the central part of the body peripheral region in the above-mentioned prior art is that the entire diaper is in close contact with the wearer, although the excrement is not easy to leak out, but it makes the wearer feel stuffy.

Embodiment Construction

[0012] Hereinafter, the disposable diaper related to the present invention will be described in detail with reference to the accompanying drawings.

[0013] exist figure 1 The disposable diaper shown in the partial cross-sectional oblique view in FIG. 2 is composed of a cover 2 formed in the shape of panties, and a liquid-absorbing member 3 located inside the cover 2 . The covering member 2 made of non-woven fabric has a front body peripheral region (front body) and a rear body peripheral region (back body) 7 facing each other, and a crotch region 8 between these body peripheral regions 6, 7, The same side edge parts 11, 12 of the front and rear body peripheral regions 6, 7 overlap each other to form a palm-shaped connection, which is integrated with the joint regions 13 arranged alternately along the up-down direction. The covering member 2 has a body peripheral opening 16 and a pair of leg peripheral openings 17, and a body peripheral elastic elastic member 18 extending in ...

Abstract

The present invention relates to a kind of throwaway paper diaper with less sticky feeling which is composed of thin-flake covering component of hourglass type, permeable surface flake, impermeable back flake and absorbent, in which the covering component is comprised of a individual liquid-absorbent component. The circumference edge of covering component is made as elastic stretchability and the side edges of circumference of the front and rear body area are connected or made as connectable. The liquid-absorbent component is located right at the top of under-femur region extending toward the circumferential direction of the body. The extended front end has the first and second elastic component attached on the inner side of the side portion around the body of covering component.

Description

technical field [0001] This invention relates to disposable diapers. Background technique [0002] Existing disposable diapers composed of liquid-absorbent materials sandwiched between a liquid-permeable outer sheet and a liquid-impermeable inner sheet have a planar shape in the shape of an hourglass, with a gap between the side edges of the front and rear body peripheral regions. Two forms are known, the open type in which a releasable connection is formed between them, and the panty type in which a peelable or non-peelable connection is formed between the side edges of the front and rear peripheral regions. These two kinds of diapers often install elastic stretching parts extending toward the body peripheral direction on at least one of the front and rear body peripheral region edges in order to prevent slipping after wearing or to improve the adhesion between the liquid absorbing part and the body. And often on the central part of the up and down direction of these two b...
