    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 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 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 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.
