  • Absorbent body with fluid transport means
    Patent number: 4820295
    Abstract: An absorbent body is provided for absorbing body fluids. The body is generally planar and elongated and is surrounded by a substantially uniformly compressed peripheral edge.

  • Coextruded apertured film sanitary napkin cover
    Patent number: 4806411
    Abstract: An apertured film, suitable for use as a sanitary napkin cover which passes body fluids, is provided. The film comprises a first layer of a first polymeric material and a second layer of a second polymeric material. Both layers are apertured for the transmission of body fluids therethrough. The first polymeric material exhibits a melting point temperature which is greater than the melting point temperature exhibited by the second polymeric material. The apertured film may be thermally bonded by heating the film to a temperature in excess of the melting point temperature of the second layer material and below the melting point temperature of the first layer material. The unmelted first layer will thereby maintain the integrity of the apertured film when the second layer is in its thermally softened condition.
