  • Complete oral care toothbrush systems
    Patent number: 12029310
    Abstract: An oral care system includes a main body, and a brush manually movable between a stowed and a deployed position. The brush includes a head, and bristles having respective first ends attached to the head and distal ends together defining a bristle surface for tooth cleaning in use. A toothpaste dispensing apparatus is carried by the main body and is configured to place toothpaste directly onto the bristle surface defined by the distal ends of the bristles when the brush is in the stowed position. The dispensing apparatus is configured to place toothpaste directly onto the bristle surface defined by the distal ends of the bristles without saturating the bristles at their first ends attached to the head. The toothpaste dispensing apparatus includes a port through which toothpaste is dispensed, and the port aligns with the bristles when the brush is at the stowed position.
