  • Particulate modified elastomeric flosses
    Patent number: 6192896
    Abstract: Elastomeric polymeric flosses comprising particulate modification agents stably associated with the surface thereof, as well as methods for their fabrication, are provided. In the subject flosses, particulate modification agents are either adsorbed to the surface of the floss or embedded in the surface of the floss. To fabricate the subject flosses, unmodified elastomeric flosses are contacted with particulate modification agents under conditions which provide for the stable association of the particles with the floss surface, where the floss surface may be softened to promote embedding of the particulate modification agents in the surface of the floss.
    Type: Grant
    Filed: July 6, 1999
    Date of Patent: February 27, 2001
    Assignee: Gillette Canada Company
    Inventors: Belinda L. Tsao, Alex Angell-Atchison, Pranav Desai, Pascal Destandau, Pritpal Singh
