  • Bristled article
    Patent number: 5687446
    Abstract: The present invention relates to an improved bristled article and more particularly to an improved toothbrush which has a tuft cavity with a cross-sectional area that decreases such that the tuft cavity is broadest at the open top end and becomes narrower toward the closed bottom end of the tuft cavity. This decrease of the breadth of the tuft cavity results in a greater packing factor in the closed bottom end portion of the cavity than in the open top end and provides higher bristle retention force.
    Type: Grant
    Filed: June 21, 1996
    Date of Patent: November 18, 1997
    Assignee: Johnson & Johnson Consumer Products, Inc.
