Abstract
Abstract This diaper comprises at the level of each of its transverse edges, a strip (6)7) of open cell foam material extending transversely with respect to the diaper and fixed between the support and upper sheets of the latter. These elastic strips (6)7) are designed to come into elastic contact with the body of a user at the level of the latter's waist. The longitudinal inner and outer edges of each strip communicate respectively with the inner space of the napkin and with the outside of the latter to permit this inner space to communicate thus with the outer space through the thickness of the strips so as to permit the internal ventilation of the napkin.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
128 words
Diaper comprising a flexitle (1) and impermeable support sheet, a flexible and permeable top (3) sheet joined to the support sheet over at least a portion of the periphery of the diaper, a pad of absorbent material arranged between the top sheet and the support sheet and elastic means (6, 7), positioned over at least a portion of the periphery of the diaper, designed to be applied elestically to the body of a user of this diaper, wherein the elastic means comprise at least one strip (6, 7) of an elastic material of open cell foam, arranged between the support sheet and the top sheet so that the inner space of the diaper communicates with the outside of the latter through the thickness of each of said strips.
Claim 2
Dependent Claim
128 words
Diaper comprising a flexitle (1) and impermeable support sheet, a flexible and permeable top (3) sheet joined to the support sheet over at least a portion of the periphery of the diaper, a pad of absorbent material arranged between the top sheet and the support sheet and elastic means (6, 7), positioned over at least a portion of the periphery of the diaper, designed to be applied elestically to the body of a user of this diaper, wherein the elastic means comprise at least one strip (6, 7) of an elastic material of open cell foam, arranged between the support sheet and the top sheet so that the inner space of the diaper communicates with the outside of the latter through the thickness of each of said strips.
Claim 3
Dependent Claim
94 words
Diaper according to claim 1, wherein each strip (6, 7) extencs along its wicth over at least a portion of the interval comprised between one edge of the pad (2) and the neighbouring edge of the diaper and wherein each strip is fixed on one surface to the support sheet (1) and on the opposite surface, to the top sheet (3) to connect these sheets together allowing the outer and inner longitudinal edges of each of these strips, to communicate respectively with the outside of the diaper and the inner space of the latter.
Claim 4
Dependent Claim
40 words
Diaper according to claim 1 or 2, wherein the outer edge of each strip and the neighbouring edges of the support and top sheets, are contained approximately in the same plane, leaving visible the outer longitudinal edge of the strip.
Claim 5
Dependent Claim
32 words
Diaper according to claim 3, wherein each strip extends along its width over the whole the interval comprised between the neighbouring edge of the pad and the corresponding edge of the diaper.
Claim 6
Dependent Claim
18 words
Diaper according to any one of the preceding claims, wherein the foam material of each strip is water-repellent.
Claim 7
Dependent Claim
46 words
Diaper according to any one of the preceding claims, wherein the foam material of each strip and the cross-section of the latter, are such that the strip imposes a pressure drop on the flow of a liquid through the strip whilst being permeable to gaseous fluids.
Claim 8
Dependent Claim
41 words
Diaper according to any one of the preceding claims, wherein the cross-section of each strip is such that for a sufficient traction or compression force exerted on the strip, the open cells close so as to avoid any flow of fluid.
Claim 9
Dependent Claim
40 words
Diaper according to any one of the preceding claims, wherein it comprises two strips (6) each extending transversely over at least a portion of the width of the diaper in the vicinity of a corresponding transverse edge of the latter.
Claim 10
Dependent Claim
37 words
Diaper according to any cne of the preceding claims, comprising two strips each extending longitudinally over at least a portion of the length of the diaper in the vicinity of a corresponding longitudinal edge of the latter.
