Abstract
Abstract For use with a toothpaste tube having a conical end face surrounding an exteriorly threaded nipple there is a rigid stem long enough to be grasped by a user. A hub on the stem is interiorly threaded to engage the tube threads. A bristle base having bristles therein is removably engageable with the stem. The bristle base, the stem and the hub have a connecting interior passageway to conduct toothpaste from the tube when squeezed to the bristle base. The toothpaste tube and the stem serve for manipulation of the bristles.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
152 words
A tooth care unit for use with a toothpaste tube having a substantially conical end face surrounding an outer nipple having an exterior thread comprising a rigid, elongated stem of a size readily grasped by a user; a hub on said stem having an interior thread therein adapted to engage said exterior thread; an end shoulder on said stem adapted to abut said end face; a circular-cylindrical hollow boss on said stem and extending laterally therefrom; means defining a circular passageway open at both ends and extending continuously through said hub, said stem and said boss; a plate having an opening therethrough adapted to be journalled on the exterior of said boss for rotation around said boss and relative to said stem; bristles upstanding from said plate; and means defining a radial groove in said plate adapted partially to receive said stem to inhibit free rotation of said plate around said boss.
Claim 2
Dependent Claim
152 words
A tooth care unit for use with a toothpaste tube having a substantially conical end face surrounding an outer nipple having an exterior thread comprising a rigid, elongated stem of a size readily grasped by a user; a hub on said stem having an interior thread therein adapted to engage said exterior thread; an end shoulder on said stem adapted to abut said end face; a circular-cylindrical hollow boss on said stem and extending laterally therefrom; means defining a circular passageway open at both ends and extending continuously through said hub, said stem and said boss; a plate having an opening therethrough adapted to be journalled on the exterior of said boss for rotation around said boss and relative to said stem; bristles upstanding from said plate; and means defining a radial groove in said plate adapted partially to receive said stem to inhibit free rotation of said plate around said boss.
Claim 3
Dependent Claim
141 words
A tooth care unit for use with a toothpaste tube having a substantially conical end face surrounding an outlet nipple having an exterior thread comprising a rigid, elongated stem of a size readily grasped by a user; a hub on said stem having an interior thread thereon adapted to engage said exterior thread; an end shoulder on said stem adapted to engage said end face; means on said stem on the exterior providing a journal and on the interior having a central hollow; means defining a continuous passageway open at both ends and extending through said hub and said stem and into said central hollow; a bristle block having a central opening therethrough adapted to turn on and communicate with said central hollow; and means on said bristle block defining lateral grooves therein adapted to engage said stem as a detent.
Claim 4
Dependent Claim
