  • Patent number: 4909803
    Abstract: A disposable absorbent article for absorbing liquids, particularly body fluids such as urine. An absorbent core is encased in an outer covering layer to which flaps are connected along the longitudinal sides at a proximal edge. The flaps also have a distal edge which is displaced from the absorbent core means. The flaps are elasticized to render the distal edge elastically contractible so that the flap is gathered.
    Type: Grant
    Filed: February 24, 1989
    Date of Patent: March 20, 1990
    Assignee: The Procter and Gamble Company
    Inventors: Mohammed I. Aziz, Ted L. Blaney
  • Patent number: 4808178
    Abstract: An article of manufacture is disclosed for absorbing liquids, particularly body fluids such as urine. An absorbent core is encased in an outer covering layer to which flaps are connected along the longitudinal sides. The flaps are elasticized and have a leakage resistant portion which is non-wicking, non-absorbent and liquid impermeable.

  • Patent number: 4324247
    Abstract: A disposable absorbent article having improved strike-through and rewet characteristics is disclosed. The disposable absorbent article has an embossed and perforated thermoplastic film interposed between the topsheet and the absorbent core. The topsheet, likewise, is embossed. The combination of the embossed topsheet and the embossed and perforated thermoplastic film permit liquid to rapidly penetrate the topsheet while preventing liquid in the absorbent core from flowing from the absorbent core back to the topsheet.

  • Patent number: 4323068
    Abstract: An improvement in the embossing of a thermoplastic textile, in particular the topsheet of an absorbent structure such as a diaper, which improves the high load caliper of the textile. The knobs and depressions of the mated embossing rolls used to emboss the textile have side walls which define a small angle with respect to a radius of the embossing roll. The preferred embossing knobs and depressions each define a frustum with a rhombic base and land, with the longer diagonal of the rhombus aligned in the machine direction of the embossing roll. The resulting embossed textile has stronger bosses, and thus maintains a greater caliper under load, than is observed in the prior art embossed textile.

  • Patent number: RE34920
    Abstract: A disposable absorbent article for absorbing liquids, particularly body fluids such as urine. An absorbent core is encased in an outer covering layer to which flaps are connected long the longitudinal sides at a proximal edge. The flaps also have a distal edge which is displaced from the absorbent core means. The flaps are elasticized to render the distal edge elastically contractible so that the flap is gathered.
