Abstract

A sanitary towel having a member which extends in the longitudinal direction thereof is elastically deformable particularly in the transverse direction of the towel, and is of such width that in the position of use of the towel it is elastically deformed to thereby urge the side edges of the portion of the towel situated between the thighs of the wearer into side leakage avoiding sealing engagement with adjacent leg portions irrespective of any variation in the relative positions thereof. The edges of the towel are curved upward in a prestressed position and are retained in that position by means of a strip of material that extends between the edges of the towel and is of a material that weakens upon contact with liquid, so that the strip ruptures after the towel is in place.

Claims

1. In a sanitary towel comprising an elastically deformable member extending lengthwise of the towel for sealing the edges of the towel against the body of the user, and a body of material absorptive to liquid on said elastically deformable member;

the improvement comprising a layer of material that weakens upon contact with liquid and that extends between and retains the edges of the towel closer together than when the elastically deformable member is unstressed, so that upon contact with liquid, said layer ruptures and the elastically deformable member applies the edges of the towel against the body of the user.

2. A towel as claimed in claim 1, said elastically deformable member comprising a slab of elastically deformable material.

3. A towel as claimed in claim 1, said elastically deformable member comprising a number of flexible ribs spaced apart lengthwise of the towel and held together by at least one longitudinally extending rib integral therewith.
