Patents by Inventor Andrea Lieselotte Link

Andrea Lieselotte Link has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7847144
    Abstract: The present invention relates to absorbent articles comprising superabsorbent polymer particles especially suitable for use in the fluid acquisition zone of the absorbent core. The superabsorbent polymer particles are coated with cationic polymers having 1 to 25 mol/kg, referring to the total weight of the cationic polymers, of cationic groups, which can be protonated. The cationic polymers are not substantially covalently bound to the superabsorbent polymer particles.
    Type: Grant
    Filed: September 15, 2004
    Date of Patent: December 7, 2010
    Assignee: The Procter & Gamble Company
    Inventors: Holger Beruda, Yasue Nakagawa, Andrea Lieselotte Link, Mattias Schmidt

  • Patent number: 6664439
    Abstract: An absorbent article having an ultimate fluid storage region and a fluid distribution region, positioned between the ultimate storage region and the garment oriented surface of the article, in fluid communication with the ultimate fluid storage region, the ultimate fluid storage region includes a material which has: (1) a Capillary Sorption Desorption Capacity at 100 cm (CSDC 100) of at least 10 g/g; (2) a Capillary Sorption Desorption Capacity at 0 cm (CSDC 0) higher than the CSDC 100; (3) a Loosely Bound Liquid Capacity (LBLC); and (4) a Capillary Sorption Desorption Release Height when 50% of the LBLC are released (CSDRH 50) less than 60 cm. Further, the liquid distribution layer material has a Capillary Sorption Absorption Height at 30% of its maximum capacity (CSAH 30) of at least 35 cm. Disuibution material can be foam materials, particularly those derived from high internal phase water-in-oil emulsions.
