Abstract
A toothbrush includes a head having a proximal end and a distal end furthest from the proximal end. The head also includes a top face having a plurality of bristle tufts disposed therein, a back face opposed to the top face, and a tip. An elastomeric support element covers a portion of the back face, and the tip is uncovered by the elastomeric support element. A first plurality of elastomeric elements is integrally formed with the elastomeric support element. Each of the first plurality of elastomeric elements extends individually from the elastomeric support element and terminates in a free end.
Claims25
A toothbrush head having a proximal end and a distal end furthest from the proximal end, the toothbrush head comprising:
- a top face, a back face opposed to the top face, and a tip;
- a plurality of bristle tufts attached to the head;
- an elastomeric member covering a portion of the head, wherein the elastomeric member is recessed in the head such that the elastomeric member is substantially flush with the back face;
- and
- a first plurality of elastomeric elements integrally formed with the elastomeric member, each of the first plurality of elastomeric elements extending individually from the elastomeric member and terminating in a free end;
- and
- a second plurality of elastomeric elements disposed in a central area of the head.
A toothbrush having handle and a head, the head having a proximal end and a distal end furthest from the proximal end, the head further comprising:
- a first segment comprising a plurality of bristle tufts;
- a second segment comprising a plurality of bristle tufts;
- a third segment comprising a plurality of bristle tufts;
- a first elastomeric connection between the first segment and the second segment, and a second elastomeric connection between the second segment and the third segment, wherein the first elastomeric connection and the second elastomeric connection allow the second segment to move with respect to the first segment and the third segment;
- an elastomeric member covering at least a portion of a back face;
- and
- a first plurality of elastomeric elements integrally formed with the elastomeric member, each of the first plurality of elastomeric elements extending individually from the elastomeric member and terminating in a free end.
A toothbrush having handle and a head, the head comprising:
- a first segment comprising a plurality of bristle tufts;
- a second segment comprising a plurality of bristle tufts, the second segment being longitudinally spaced from the first segment;
- a first flexible connection between the first segment and the second segment, the first flexible connection allowing the second segment to move relative to the first segment;
- a third segment comprising a plurality of bristle tufts, the third segment being longitudinally spaced from the second segment;
- a second flexible connection between the second segment and the third segment, the second flexible connection allowing the second segment to move relative to the third segment, at least one of the first flexible segment or the second flexible segment comprising an elastomer and a plastic link integrally formed with the first segment, the second segment, or the third segment;
- an elastomeric member covering at least a portion of a back face and being recessed in the head such that the elastomeric member and the back face are substantially flush;
- and
- a first plurality of elastomeric elements integrally formed with the elastomeric member, each of the first plurality of elastomeric elements extending individually from the elastomeric member and terminating in a free end.
A toothbrush having a handle, a head, and a neck disposed between the handle and the head, the head comprising:
- a first support having a top face a back face opposed to the top face, and a first plurality of contact elements, the first support comprising a first material;
- a second support recessed in the first support such that the second support is substantially flush with the back face, the second support comprising a second material which is different from the first material;
- a second plurality of contact elements integrally formed with the second support element, each of the second plurality of contact elements extending individually from the second support element and terminating in a free end, and wherein the first plurality of contact elements and the second plurality of contact elements are different;
- and
- a plurality of elastomeric elements attached to the head, the plurality of elastomeric elements being disposed in a central region of the head.
