Abstract
A diaper is provided on its inner side with a tufted sheet strip assembly. The assembly includes a plurality of sheet strips, a sheet-like base member to which fixed end zones of the respective sheet strips are permanently bonded, and elastically biasing element adapted to space a transversely intermediate zone of the sheet-like base member from the inner side of the diaper.
Claims9
A disposable diaper, comprising:
- a crotch region having a longitudinal direction and a transverse direction orthogonal to said longitudinal direction, a front waist region extending forward from said crotch region, and a rear waist region extending rearward from said crotch region,
- opposite inner and outer surfaces, and
- a tufted assembly attached to said inner surface in any one of said regions so as to extend in said transverse direction in orthogonal relationship with a center line that extends in said longitudinal direction and bisects widths of respective said regions,
- said assembly comprising:
- a plurality of sheet strips,
- a base sheet extending in said transverse direction and supporting thereon said sheet strips each having at least one end zone thereof pennanently bonded to said base sheet, and
- an elastically biasing element adapted to space at least a transversely middle zone of said base sheet from said inner surface in a thickness direction defined from said outer surface toward said inner surface.

- a tufted assembly attached to said inner surface in any one of said regions so as to extend in said transverse direction, said assembly comprising:
- a plurality of sheet strips,
- a base sheet extending in said transverse direction and supporting thereon said sheet strips each having at least one end zone thereof permanently bonded to said base sheet, said base sheet has a transversely middle zone free of direct attachment to the inner surface of said diaper, and
- an elastically biasing element biasing the transversely middle zone of said base sheet to be spaced upwardly from the inner surface of said diaper so as to define, between said transversely middle zone of said base sheet and the inner surface of said diaper, a passage for bodily discharge to flow in the longitudinal direction on said inner surface and under the transversely middle zone of said base sheet.
