Abstract: An oral care implement for dispensing an oral care agent includes a housing, reservoir therein containing an oral care fluid, and an electrical circuit comprising first and second electrodes connected to an onboard power source. Each electrode is in contact with the oral care fluid in the housing. An actuator, operably coupled to the power source, is configured to both selectively energize the circuit and activate dispensing of the oral care fluid. An electrical charge is applied to the oral care fluid by activating the actuator when dispensing the oral care fluid. When the fluid comprises a peroxide based tooth whitening agent, the dispensed fluid pH is increased by the electrical charge which improves the efficacy of the whitener. In one embodiment, the implement is a modular system including a powered base unit and one or more interchangeable cartridges each having a reservoir containing an oral care fluid.

Abstract: An oral care implement that dispenses an oral care agent during use and a method of assembling such an oral care implement. The method may include contacting a suction tool to a supporting member and then contacting the supporting member to a dissolvable element to form a sub-assembly. Next, the sub-assembly may be inserted into a cavity of a head portion of an oral care implement. Then, the suction force applied by the suction tool onto the sub-assembly may be released to leave the sub-assembly in the cavity of the head portion. Finally, an oral cleaning member may be coupled to the head portion of the oral care implement.

Abstract: A fluid supply apparatus with leakage protection. The apparatus includes a housing defining a storage cavity having a total volume including a fluid portion and a gas portion. The storage cavity extends along a cavity axis from a first end to a second end. A capillary member is fluidly coupled with the fluid. A vent tube having a primary vent passageway and a plurality of vent apertures is located in the storage cavity. The primary vent passageway forms a pathway from the vent apertures to the external atmosphere. Fluid cannot flow through the vent apertures at ambient temperature and pressure equilibrium. The vent apertures may be located and arranged on the vent tube such that irrespective of vertical and angular orientation of the housing relative to a gravitational vector at least one of the vent apertures is in spatial communication with the gas.

Abstract: An oral care process which includes initiating a first operational sequence which includes generating an electric potential between a first sacrificial electrode and a second sacrificial electrode, the electric potential in the first operational sequence beginning with one of a first polarity and a second polarity, stopping the first operational sequence, and commencing a second operational sequence which includes generating the electric potential between the first sacrificial electrode and the second sacrificial electrode. The electric potential in the second operational sequence may begin with the other of the first polarity and the second polarity. The electric potential may be alternated between the first polarity and the second polarity at predetermined intervals during at least one of the first operational sequence and the second operational sequence.
