Abstract: A liquid supply apparatus with leakage protection. The apparatus includes a housing defining a storage cavity having a total volume including a liquid portion and a gas portion. The storage cavity extends along a cavity axis. A capillary member is fluidly coupled with the liquid to transport the liquid to the external atmosphere. The apparatus includes a plurality of vents that prevent liquid from flowing therethrough while permitting air to pass therethrough. A hub component is mounted within the storage cavity and it includes a plurality of radial vent passageways extending between the storage cavity and a primary vent passageway, which in turn forms a pathway to the external atmosphere. The vents may be located and arranged such that irrespective of inclination and rotational orientation of the housing relative to a gravitational vector at least one of the vents is in spatial communication with the gas.

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.
