Abstract
A sanitary napkin having a top sheet and an absorbent core associated with the topsheet is disclosed. The topsheet and associated core are decoupled from the backsheet of the sanitary napkin so that the topsheet and backsheet may be separated in the Z-direction. The sanitary napkin has a joined transverse edge connecting the top sheet and backsheet and forming a hinge to facilitate the Z-direction separation. The sanitary napkin further controls the amount of separation of the topsheet and associated core from the backsheet. A preferred way to control the amount of separation of the topsheet and associated core from the backsheet is longitudinally oriented pleats.
Claims9
A sanitary napkin having two spaced apart transverse edges, said sanitary napkin comprising:
- a liquid pervious topsheet;
- a liquid resistant backsheet joined to said topsheet along one said transverse edge and unattached to said topsheet along the other said transverse edge, whereby said backsheet may be separated from said topsheet at said unattached transverse edge;
- an absorbent core associated with said topsheet and intermediate said topsheet and said backsheet;
- and
- a means for controlling the separation of said topsheet from said backsheet.
A sanitary napkin having two longitudinal ends and two spaced apart transverse edges, said sanitary napkin comprising:
- a liquid pervious topsheet;
- a liquid resistant backsheet, said topsheet and said backsheet being joined at one said transverse edge and unattached at the other said transverse edge, whereby said backsheet may be separated from said topsheet at said unattached transverse edge;
- an absorbent core associated with said topsheet and intermediate said topsheet and said backsheet;
- and
- a longitudinally oriented pleat which joins said topsheet and said backsheet, whereby said longitudinally oriented pleat controls the separation of said backsheet from said topsheet.
A sanitary napkin having two transverse edges, said sanitary napkin comprising:
- a liquid pervious topsheet;
- a liquid resistant backsheet joined to said topsheet along one said transverse edge and unattached to said topsheet at the other said transverse edge, said backsheet being joined to said topsheet by flaccid material, whereby said topsheet may be separated from said backsheet at said unattached transverse edge until restrained by said flaccid material becoming taut;
- and
- an absorbent core associated with said topsheet and intermediate said topsheet and said backsheet.
