Abstract
In an absorbent product such as a diaper comprising a back sheet, an absorber, and a skin contact sheet, the skin contact sheet is disposed on the absorber as the uppermost layer which comes in contact with the skin of the wearer and has openings which allow the passage of excretions. The absorber and the skin contact sheet are joined only at both ends of the absorbent product in the longitudinal directions.
Claims3
An absorbent product comprising:
- a portion which is constituted of a liquid-impervious back sheet and an absorber superposed upon the back sheet and which extends to a back body portion positioned on a back side from a front body portion positioned on a front side of a wearer in a wearing state,
- wherein a skin contact sheet as an uppermost layer in contact with a wearer's skin is disposed on the absorbent product,
- the skin contact sheet includes at least one opening to allow passage of excretions from the wearer,
- each ends of said skin contact sheet are joined to opposite ends in a longitudinal direction of the absorbent product so that said skin contact sheet is kept in its entirety in a non-contact state with said absorbent product except at longitudinal-direction opposite ends of said skin contact sheet and so that a gap can be formed between said absorbent product and said skin contact sheet, and
- the skin contact sheet is connected to a stretchable band member at the ends of the skin contact sheet in the longitudinal direction, and thereby the skin contact sheet can elastically be displaced with respect to a wearer's body in an appropriate range,
- wherein the stretchable band member includes a pair of front and back slits formed along a waist surrounding opening, and elastic members attached to positions disposed opposite to each other via each slit so as to obtain an extended state in the wearing state, each of the opposite ends of the skin contact sheet in the longitudinal direction is joined to the stretchable elastic band member in the vicinity of each of the pair of slits, and a dimension of the skin contact sheet positioned between the pair of slits in the longitudinal directions is set to be shorter than an extension dimension between the pair of slits.
