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 personal care implement, such as an oral care implement, that includes a body containing a supply of a fluid. A flow barrier is positioned with a first surface adjacent to the supply of fluid and a second surface opposite the first surface. The flow barrier allows flow of the fluid through the flow barrier for application to a biological surface when the flow barrier is compressed and prevents or inhibits flow of another fluid that is in contact with the second surface of the flow barrier through the flow barrier in a static state. In certain embodiments, the fluid in the supply may have a first viscosity and a first surface tension and the another fluid may have a second viscosity and a second surface tension such that one of the first and second viscosities and one of the first and second surface tensions are different from each other.

Abstract: A method of priming an applicator of a personal care implement with a fluid. The method may include flowing a fluid along a first capillary member from a reservoir of a fluid supply system to an applicator of a personal care implement along a first fluid flow path, and flowing the fluid along a second capillary member from the reservoir of the fluid supply system to the applicator of the personal care implement along a second fluid flow path that is distinct from the first flow path. In one aspect, the fluid flowing along the second fluid flow path reaches the applicator before the fluid flowing along the first fluid flow path. In another aspect, the first capillary member is formed of a non-absorbent material and the second capillary member is formed of an absorbent material.

Abstract: A method of whitening teeth. The method may include delivering a buffer solution from a reservoir of a toothbrush to one or more tooth cleaning elements of the toothbrush; applying a toothpaste containing a peroxide to the tooth cleaning elements, the toothpaste having a first pH; and brushing the teeth with the tooth cleaning elements, thereby mixing the buffer solution and the toothpaste to form, at surfaces of the teeth, a tooth whitening mixture having a second pH that is greater than the first pH.

Abstract: An oral cavity treatment device including a power component and a tray component that are detachably coupled together. The power component may include a housing having a cavity and a power source located therein. The tray component may include a tooth receiving channel and may have a first electrode and a second electrode located on opposite sides of the tooth receiving channel. The tray component may be detachably coupled to the power component in: (1) a first configuration whereby the first electrode is operably coupled to a positive terminal of the power source and the second electrode is operably coupled to a negative terminal of the power source; and (2) a second configuration whereby the first electrode is operably coupled to the negative terminal of the power source and the second electrode is operably coupled to the positive terminal of the power source.

Abstract: An oral care device may include: a body including a head; a plurality of teeth cleaning elements extending from the head; a first sacrificial electrode on the head; a second sacrificial electrode on the head and spaced apart from the first sacrificial electrode; a power source; and a controller configured to alternate between an ON state and an OFF state, wherein: in the ON state the controller operably couples the power source to the first and second sacrificial electrodes to create an electric potential between the first sacrificial electrode and the second sacrificial electrode, the electric potential having one of a first polarity and a second polarity, and for each successive transition from the OFF state to the ON state, the controller is configured to alternate between the first polarity and the second polarity.
