A multi-component brush apparatus is described and can be used in the application of any fluid (for example, paint). The brush apparatus includes a cylindrical reservoir for holding a volume of a fluid material, a distributor attached to the cylindrical reservoir and used to transport the fluid from the reservoir along a set of small-sized tubes (pipes) disposed within the brush bristles. A piston is included and engages with the reservoir to advance the movement of the fluid material toward the distributor.

A capsule integrated with a nail polish applying element for usage by a nail polish application apparatus comprising a capsule compartment and a pressure applying element, the capsule comprising a container defining a reservoir containing nail polish fluid, the container comprising an upper face with an opening sealed with a sliding gasket and a bottom face, wherein a volume of the reservoir is reduced and an internal pressure is built in the reservoir when pressure application slides the sliding gasket towards the bottom face, and a container housing comprising a body portion shaped to receive and accommodate the container, one or more conveying tunnels having a proximal end mechanically fixated to a bottom side of the body portion and a nail polish applying element mounted to receive the nail polish fluid from a distal end of the conveying tunnel(s) for applying the nail polish fluid on a nail surface.

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.

The invention provides an oral care system comprising a gel in a pen dispenser, the dispenser comprising a chamber which permits dispensing of a measured amount of the gel, wherein the gel exhibits a Herschel-Bulkley yield stress of 10 to 230 dynes/cm2, a Herschel-Bulkley viscosity of 3 to 500 poise, and a Herschel-Bulkley rate index of 0.4 to 0.6, the specific viscosity permitting efficient application of the gel, as well as methods of using the same.

A toothpaste dispensing toothbrush has a longitudinal, hollow, cylindrical housing, an open distal end, and an open proximal end. The distal end is tapered to a blunt, open extremity. The proximal end has a predetermined inside diameter. The cylindrical housing also has a transparent longitudinal window located along its outer surface. A toothbrush head is removably affixed to the distal end of the housing. A hollow, cylindrical toothbrush cartridge chamber has an open proximal end and an outside diameter smaller than the inside diameter of the housing proximal end, to facilitate insertion of the cartridge chamber into the proximal end of the housing. A movable piston is disposed in the cartridge chamber and a slidable button is located on the housing and connected to the movable piston. A dome cap is removably affixed to the proximal end of the cartridge chamber to retain toothpaste introduced into it. A dental floss container can be removably attached to the toothbrush and an LED light can be added to illuminate areas of the mouth being brushed.

Embodiments of hair care apparatus and methods are provided generally comprising a location to provision hair care product, an applicator and a manipulator configured to enable concurrent product application and hair manipulation, and may comprise a product heater, configured to heat product provisioned therein, or be configured for use with an external heating source such as a microwave oven, and provide application of heated product at temperatures both safe for hair health and enhanced absorption. Apparatus may comprise a source of pressure, such as a pump or piston, to generate hair product flow through an applicator, and may be configured to receive product in user fillable or prepackaged product cartridges usable in the apparatus, a product chamber within the apparatus or a removable product reservoir useable in the apparatus. An apparatus may further be configured to support a plurality of manipulators, active applicators and passive applicators.

A device includes a pump and a brushhead. The pump includes a housing and plunger. The housing has an upper opening, a cavity configured to store a composition therein, and a tip having a dispensing opening. The plunger is slidably disposed within housing such that it is moveable with respect to the housing. The brushhead includes a first plurality of bristle bores and a second plurality of bristle bores, each of which extend from a bottom surface of the brushhead towards an opposing top surface and have a bristle bundle extending therefrom. The brushhead includes a generally central throughhole extending between the bottom surface and the opposing top surface. The pump is coupled to the brushhead via the tip of the housing such that actuation of the plunger causes a portion of the composition stored in the housing to be dispensed on at least a portion of the bristle bundles.

An oral care implement having a body having 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 and for storing an oral care fluid; and a supply mechanism connected to the body, the supply mechanism having a user-operable selector comprising a cam, and an actuator comprising a follower in contact with the same, the actuator operable to cause the oral care fluid to flow from the reservoir towards the fluid outlet, and wherein the cam is movable relative to the body to cause movement of the follower relative to the body and thereby operate the actuator.

A dispenser with a transfer assembly is arranged to efficiently transfer a stored liquid from a reservoir in a body of the dispenser to an applicator. The transfer assembly includes an adapter, applicator base, piston and a bias member. The adapter is in contact with the body and has a central member with orifices to fluidly couple the applicator base to the reservoir. The applicator base is supported by and extends beyond the adapter. The applicator base forms a cavity for housing the piston and the bias member. A tubular member of the applicator base supports an applicator. The piston includes a passage that conveys the stored liquid from the cavity to the applicator. The bias member keeps the head of the piston against a surface of the central member. When stored liquid is under a pressure that exceeds a bias force, displacement of the piston, opens a seal.

A capsule integrated with a nail polish applying element for usage by a nail polish application apparatus comprising a capsule compartment and a pressure applying element, the capsule comprising a container defining a reservoir containing nail polish fluid, the container comprising an upper face with an opening sealed with a sliding gasket and a bottom face, wherein a volume of the reservoir is reduced and an internal pressure is built in the reservoir when pressure application slides the sliding gasket towards the bottom face, and a container housing comprising a body portion shaped to receive and accommodate the container, one or more conveying tunnels having a proximal end mechanically fixated to a bottom side of the body portion and a nail polish applying element mounted to receive the nail polish fluid from a distal end of the conveying tunnel(s) for applying the nail polish fluid on a nail surface.
