Abstract: A personal care system or fluid supply system with components specifically designed and arranged to speed up the process of initially priming an applicator of the personal care system with a fluid. The personal care system may include a personal care implement having an applicator and a fluid supply system disposed within the personal care implement. The fluid supply system may include multiple reservoirs, both filled with a fluid, and one of which has an absorbent member disposed therein. A first capillary member may extend from one of the reservoirs to the applicator and a second capillary member may extend from the reservoir with the absorbent member therein to the applicator. The fluid may travel faster along the second capillary member to speed up the priming process.

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 plurality of vent apertures are formed into the housing, each forming a passageway between the storage cavity and an external atmosphere and each configured such that the fluid cannot flow through the vent apertures at ambient temperature and pressure equilibrium between the storage cavity and the external atmosphere. The vent apertures may be located and arranged on the housing 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: A tooth sensitivity treatment device and an applicator tip thereof. The tooth sensitivity treatment device may be configured to dispense a sensitivity formulation onto a user's teeth. The tooth sensitivity treatment device may further be configured to massage the sensitivity formulation onto the user's teeth after dispensing. The applicator may have a bottom end, a top end, and a longitudinal axis extending therebetween. The applicator may include an application portion that is not intersected by the longitudinal axis. The application portion may have an outer surface that is oriented at an oblique angle relative to the longitudinal axis. The applicator may include a resilient material component and a rigid material component that are integrally coupled together. The resilient material component may form the entirety of the application portion to increase flexibility while massaging the sensitivity formulation onto the user's teeth.

Abstract: An oral care implement that dispenses an oral care agent during use and a method of assembling such an oral care implement. The oral care implement may include a body having a head portion. The head portion may have a cavity with an open end. There may be at least one opening extending from the cavity to an outer surface of the head portion. A dissolvable element that includes an oral care agent may be positioned in the cavity. Furthermore, a supporting member may be positioned in the cavity. The supporting member may include a first coupling feature that couples the supporting member to the dissolvable element. Finally, an oral cleaning member may be coupled to the head portion to close the open end of the cavity.

Abstract: A personal care implement with a fluid dispensing system includes a fluid applicator, a fluid dispensing assembly including main and overflow reservoirs, and a capillary member in fluid communication with the reservoirs and the applicator for dispensing personal care fluid stored in the reservoirs via capillary action. An air venting system in one arrangement allows ambient air to be drawn into the main reservoir through the overflow reservoir for alleviating vacuum formed in the main reservoir by the capillary action fluid dispensing process. The venting system may include an external vent to atmosphere from the overflow reservoir and an internal vent between the reservoirs. In the event air trapped within the main reservoir expands due to changes in altitude or temperature, fluid in the main reservoir is expelled into the overflow reservoir via the internal vent. In one implementation, the personal care implement may be an 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.
