A dental cleaning appliance includes a handle, a fluid reservoir for storing a working fluid, and a fluid delivery system for receiving working fluid from the fluid reservoir, and for delivering the working fluid to the teeth of a user. The fluid reservoir is delimited by a wall and a movable member which is moveable relative to the wall to vary the volume of the fluid reservoir. An expansion chamber is located adjacent to the moveable member. The volume of the fluid reservoir decreases, and the volume of the expansion chamber increases, as fluid is supplied to the fluid delivery system during use of the appliance.

An oral care system includes a toothbrush and a dispenser detachably coupled to the toothbrush. The dispenser includes a collapsible bladder containing an oral care material. A compression device assembly includes an actuator operably coupled to a compression device movably mounted inside the dispenser. In one embodiment, the compression device includes a feed slot that engages opposite sides of the collapsible bladder. Actuating the actuator translates the compression device in a first longitudinal direction extruding and dispensing the oral care material from the oral care product dispenser. The actuator may be slideably mounted to the dispenser in one embodiment. A ratcheting mechanism may be provided to provide indexed movement of the compression device, thereby dispensing predetermined doses of the oral care material with each indexed movement.

An oral care system includes a toothbrush and a dispenser detachably coupled to the toothbrush. The dispenser includes a chamber containing an oral care material. A compression device assembly includes an actuator operably coupled to a compression device movably mounted inside the dispenser. In one embodiment, the actuator may be a ratcheting rocker switch that alternatingly engages gear racks formed on the dispenser housing. Actuating the rocker switch imparts pivotable and indexed linear motion to the switch. This in turn axially translates the compression device in a first longitudinal direction thereby compressing and extruding the oral care material from the dispenser. The corresponding indexed movement of the compression device dispenses predetermined doses of the oral care material providing precise control over the amount of oral care material dispensed.

An oral care implement including a body comprising a handle, a head at an end of the handle, and at least one fluid outlet, the head having at least one oral care element extending therefrom; a reservoir, in the body, for storing an oral care fluid; and a pump for pumping the oral care fluid from the reservoir towards the fluid outlet, wherein the pump comprises a first check valve downstream of the reservoir, and a second check valve downstream of the first check valve and upstream of the fluid outlet. One of the first and second check valves comprises a valve seat defining an opening through which the oral care fluid is flowable, a valve member separate from the valve seat and comprising a stopper movable linearly relative to the valve seat, and a resilient element separate from the valve member and biasing the stopper towards the valve seat.

Disclosed is a fluid dispenser, comprising: a housing having an internal reservoir for containing a fluid, such as an oral care fluid, and an applicator connected to the housing. The applicator comprises a base having an exterior surface, the base comprising a valve having a movable portion defining an outlet of the valve and forming part of the exterior surface, and one or more projections extending from the exterior surface adjacent the valve outlet. The valve is for selectively blocking a passageway that is in fluid communication with the internal reservoir.

A brush (200) for cleaning a periodontal pocket between a tooth and a gum of a user. The brush (200) comprises: a handle portion (205); an arm extending (210) from the handle portion; and a brush head (211) located at an end of the arm having a plurality of brush filaments (212) extending therefrom. The brush filaments (212) are configured to be inserted into a periodontal pocket. The brush (200) can be used to assist in the treatment of gum disease by enabling a user to precisely clean periodontal pockets. The brush (200) may be for self-use. Alternatively, the brush (200) may be used by a healthcare professional such as a dentist or hygienist to treat a patient or to demonstrate its use.

A garbage disposal cleaning system includes a garbage disposal that may be fluidly coupled to a drain on a sink. A scrubbing unit is removably positioned within the garbage disposal. The scrubbing unit frictionally engages the garbage disposal. The scrubbing unit contains and releases a detergent. The scrubbing unit cleans the garbage disposal when the garbage disposal is turned on. Thus, the scrubbing unit may reduce an odor relating to bacterial decay in the garbage disposal.

An oral care implement comprises a handle having a container containing oral care fluid, A head includes tooth cleaning elements and a fluid outlet to output fluid into the vicinity thereof. A manually actuatable pump mechanism in the handle between the container and fluid outlet is connected thereto by respective first and second conduits. The pump mechanism comprises a chamber having an inlet connected to the first conduit, an outlet connected to the second conduit, and an actuatable valve mechanism for selectively opening the inlet and outlet respectively to cause fluid flow into and out of the chamber. The mechanism comprises first and second valve elements and a deformable actuator connected to the first and second valve elements. A wall which defines at least a part of the chamber is adapted to be manually moved to operate the valve mechanism.

A toilet bowl brush assembly, a toilet bowl brush, and a method of manufacturing the same. The brush includes a handle assembly that has a proximal end and a distal end and a brush head that includes a plurality of tufts of bristles disposed on an outer surface of the brush head, a cavity defined by an inner surface of the brush head, and a fastener portion. The toilet bowl brush assembly includes a base that forms a cup for receiving the brush head. The brush head selectively couples to the handle assembly distal end at the fastener portion of the brush head at a handle assembly-brush head connection. At least one of the base and the brush head define an interference feature for preventing the brush head from moving relative to the base as the handle assembly is selectively separated from the brush head.

The invention relates to a container for a tool with a tool head. The tool head has conduits conducting liquid extending through the tool head. The container is attachable to the tool head. In use, the container is filled with liquid. The container comprises a tubular diaphragm held extended by at least one spacer element. The tubular diaphragm is in use at its lower end air tightly attached to the tool head. The membrane is easily compacted into an element that takes up a small storage volume, but is still able to remain outstretched into a container due to the spacer element, even when subjected to external fluid pressure.

The spacer element comprises filler openings. The tool has a shaft and the spacer element has a tool connection surrounding the tool shaft. In this manner, the container is guided up and down the shaft as the container is erected and contracted.
