    Abstract: An toothbrush having a handle and a head. The handle may include a first component and a second component covering at least a portion of the first component. The first and second components may be chemically compatible. The first and second components may both comprise a hard polyolefin. The first and second components may have different transparencies. In one aspect, the first component may be opaque and the second component may be transparent or semi-transparent. In some aspects, the handle may also include a third component comprising a thermoplastic elastomer. Furthermore, there may be at least one projection extending outwardly from an outer surface of the first component.

    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: In one embodiment, the invention can be a system for determining toothbrush effectiveness, the system comprising a data capture subsystem comprising at least one sensor and configured to generate brushing data during a participant brushing session directed entirely by the participant. A brushing simulation subsystem includes a robotic arm configured to hold a toothbrush, and receive from at least one processor instructions for a motion to be carried out by the robotic arm. The motion of the robotic arm causes the toothbrush to carry out an automated brushing session upon the artificial teeth, the motion of the robotic arm being based on the brushing data captured during the participant brushing session. The at least one processor is further configured to determine an effectiveness of the toothbrush based on the substance determined to be removed from artificial teeth during an automated brushing session.

    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.
