  • Patent number: 10342648
    Abstract: A powered toothbrush apparatus with capacitive touch control is disclosed. The tooth brush includes a head portion having an oscillating tuft block driven by a motor, a handle portion, and an elastically deformable capacitive touch control panel mounted in the handle portion. In one embodiment, the control panel includes a plurality of capacitance sensor buttons each having movable sensor targets paired with a corresponding capacitance sensor electrically connected to a programmable microprocessor. Applying finger pressure on the control panel adjacent a sensor target changes capacitance of the sensor button. The microprocessor detects the change in capacitance, which controls the operating mode of the toothbrush including on/off, motor speed, brushing mode such as pulse, or other. A related operating method is disclosed.

  • Publication number: 20190175320
    Abstract: An oral care implement handle or a refill head therefor. The oral care implement handle may include a gripping portion and a stem protruding from a shoulder of the gripping portion. The stem may include a post located at a distal end of the stem. The post may have a non-circular transverse profile. More specifically, the post may include a hub portion and a protuberance that either protrudes radially from a side surface of the hub portion, protrudes upward from the shoulder of the gripping portion, or both. The refill head may include a sleeve having an inner surface that defines an internal cavity. The internal cavity may include a central portion and at least one slot portion extending radially from the central portion. Thus, the internal cavity of the sleeve portion may have a profile configured to receive the stem of the oral care implement handle.

  • Publication number: 20190174906
    Abstract: An oral care refill head and an oral care kit comprising the same. The oral care refill head may include a sleeve portion, a head portion, and an elastomeric prophy cup. The sleeve portion may have an inner surface that defines an internal cavity for receiving a portion of a stem of an oral care implement handle therein so that the oral care refill head can be repetitively attached to and detached from the oral care implement handle. The elastomeric prophy cup may comprise an outer surface that forms at least a portion of a peripheral side surface of the head portion. The elastomeric prophy cup may be formed by injection molding an elastomeric material onto a support portion of the head portion. The oral care refill head may be packaged together with a store of an anti-sensitivity oral care material to form a kit.
