    Abstract: A sanitary napkin is disclosed which has an absorbent and a fluid-permeable cover positioned over at least one surface of the absorbent. The cover is formed from a nonwoven web having a network of essentially unbroken thermoplastic fibers. The web has a plurality of apertures formed therethrough which are located in a predetermined area which represents less than about 80% of the surface area of the cover. Each of the apertures is surrounded by a consolidated ring formed of thermally set thermoplastic fibers which in turn is surrounded by a raised area which contacts the body of the user. The apertures formed in the web occupy about 20% to 55% of the predetermined area and permit body fluid to quickly pass through to the absorbent.

    Abstract: A sanitary device, e.g. a sanitary napkin is provided which has an absorbent matrix and a fluid impervious baffle. Part of the fluid impervious baffle is a heat fusible sheet which is adhered to the absorbent component by fusing. The absorbent component may have heat fusible material interspersed therein and may have a fluid pervious upper layer which is essentially coterminous with or wraps about the absorbent component or the absorbent component and baffle combination. When a fluid pervious wrap is used, it is preferred that the wrap be fusible and also be fused to the baffle. The fusing is preferably accomplished in random sites across the surface of the sanitary appliance, e.g. by embossing.
