Abstract
Abstract A disposable nappy for a baby comprises at least one sheet of flexible impermeable material comprising two longitudinal edges intended to define the openings for the baby's legs and two transverse edges intended to define a waist portion and an absorbent pad superimposed on a central region of the impermeable sheet. The nappy is characterised in that it comprises respectively in the immediate vicinity of each of the longitudinal edges; on either side of the pad, a flexible longitudinal sheath inside which a flexible longitudinal tie is able to slide and in that each sheath comprises means for gaining access to the corresponding flexible tie in order to enable the latter to be gripped manually and to be tensioned at will in order to reduce the apparent length of the longitudinal edges; to press the latter at will around the baby's legs and to give the disposable nappy the shape of a trough, between the latter.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
248 words
A disposable nappy for a baby, comprising a sheet of flexible impermeable material having two longitudinal side edges intended to define opening for the legs of a baby and two transverse end edges intended to define a waist portion, an absorbent pad superimposed on a central region of said impermeable sheet with longitudinal side edges of said pad spaced inwardly from longitudinal side edges of said impermeable sheet, the longitudinal side edges of said impermeable sheet being folded inwardly on themselves and secured to said impermeable sheet along longitudinal junction lines at a distance from the folds to form longitudinally extending tubular sheaths at opposite sides of said nappy, said pad being disposed only on a central region of said impermeable sheet between said longitudinal junction lines, a flexible longitudinal tie located inside each of said sheaths and able to slide therein, said nappy being folded over on itself along longitudinal lines to form a central portion, opposite side portions extending inwardly from first fold lines toward a longitudinal center line of said nappy, and opposite edge portions extending outwardly from second fold lines, said edge portions comprising said sheaths, and means providing access to at least one end of each of said longitudinal ties in order to make it possible to grip the latter manually and tension them to reduce the effective length of said sheaths and thereby press the latter around the baby's legs to give the nappy the shape of a trough between said sheaths.
Claim 2
Dependent Claim
248 words
A disposable nappy for a baby, comprising a sheet of flexible impermeable material having two longitudinal side edges intended to define opening for the legs of a baby and two transverse end edges intended to define a waist portion, an absorbent pad superimposed on a central region of said impermeable sheet with longitudinal side edges of said pad spaced inwardly from longitudinal side edges of said impermeable sheet, the longitudinal side edges of said impermeable sheet being folded inwardly on themselves and secured to said impermeable sheet along longitudinal junction lines at a distance from the folds to form longitudinally extending tubular sheaths at opposite sides of said nappy, said pad being disposed only on a central region of said impermeable sheet between said longitudinal junction lines, a flexible longitudinal tie located inside each of said sheaths and able to slide therein, said nappy being folded over on itself along longitudinal lines to form a central portion, opposite side portions extending inwardly from first fold lines toward a longitudinal center line of said nappy, and opposite edge portions extending outwardly from second fold lines, said edge portions comprising said sheaths, and means providing access to at least one end of each of said longitudinal ties in order to make it possible to grip the latter manually and tension them to reduce the effective length of said sheaths and thereby press the latter around the baby's legs to give the nappy the shape of a trough between said sheaths.
Claim 3
Dependent Claim
50 words
A nappy according to claim 1, further comprising a sheet of permeable material covering said pad on the side intended to face the baby, side edge portions of said permeable sheet extending laterally beyond side edges of said pad and secured to said impermeable sheet along said longitudinal junction lines.
Claim 4
Dependent Claim
16 words
A nappy according to claim 1 or claim 2, in which said longitudinal ties are elastic.
Claim 5
Dependent Claim
53 words
A nappy according to claim 1 or claim 2, in which said ends of said ties are flush with the end of said nappy, said means for providing access to at least one end of each of said ties comprising an opening in said sheath located inwardly from the end of said nappy.
Claim 6
Dependent Claim
62 words
A nappy according to claim 1 or claim 2, in which one end of each of said longitudinal ties is secured to said impermeable sheet at one end of said nappy, and in which said means for gaining access to each of said ties comprises an opening in the respective sheath at a location inwardly of the opposite end of said nappy.
