This invention involves a device forming a sanitary napkin. The device includes a preformed, usually biconcave fluid-absorbent pad component (2) defining a biconcave central area (8) of reduced width, entirely arranged inside a covering (10) which is permeable to said fluids, and a layer (16) made of a component impermeable to fluids which is inserted between the pad component (2) and said covering (10), characterized in that said covering (10) is designed with a width (L) larger than width (l) of said pad component (2) at the level of said biconcave reduced-width area (8), thus defining side wings or flaps (20, 22) that are sealed together. This device improves lateral tightness while providing excellent comfort.
Article for forming a sanitary or similar napkin, in particular for women's hygiene, including a preformed fluid-absorbent pad component defining a central biconcave area of reduced width, entirely arranged inside a covering that is permeable to said fluids, and a layer of a component impermeable to fluids which is inserted between said pad component and said covering, characterized in that said covering is designed with a width larger than the width of said pad component at the point of said reduced-width biconcave area, thus defining lateral wings or flaps that are sealed together so as to improve lateral tightness to said fluids, said lateral wings or flaps being provided with one or more pleats shaped as arcs of a circle which are concentric with adjacent concavity that are sealed together, further improving lateral tightness.
