Liquid supply apparatus and personal care implement containing the same

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.
