A cosmetic tool comprises a brush head, a material core, a movable sleeve, a fixed sleeve, and a transmission structure. The material core is mounted in the movable sleeve, the brush head is located at one end of the movable sleeve and is arranged opposite the material core, and a discharge port is formed in an end face of the material core facing the brush head. The fixed sleeve is sleeved outside the movable sleeve, and the movable sleeve can move along an axial direction. The fixed sleeve, the movable sleeve and the brush head are connected by means of a transmission structure, and when the movable sleeve moves along the axial direction, the movable sleeve drives the brush head) to turn over by means of the transmission structure, so as to dip in a cosmetic substance at the discharge port.

Bush applicators including hair brush applicators and containers for dispensing dry shampoo are provided. In one embodiment, a brush applicator includes a body having one or more channels to distribute material to a bristle assembly. The bristle assembly can include a plurality of bristle and brush elements. The brush elements may be interspersed with the bristle elements and can each include a shaft and end (e.g., tip). Another embodiment is directed to a brush applicator including a container coupled to a body. The container retains at least one material including powder, liquids and solutions. Another embodiment is directed to a brush applicator configured for application of dry shampoo to hair.

A cap for a scalp care container is capable of applying a liquid which is coupled to the scalp care container. The cap includes an upper cap provided with a plurality of bristles, and a lower cap coupled to the upper cap and fastened to the scalp care container.

An oral care implement for dispensing an oral care agent includes a housing, reservoir therein containing an oral care fluid, and an electrical circuit comprising first and second electrodes connected to an onboard power source. Each electrode is in contact with the oral care fluid in the housing. An actuator, operably coupled to the power source, is configured to both selectively energize the circuit and activate dispensing of the oral care fluid. An electrical charge is applied to the oral care fluid by activating the actuator when dispensing the oral care fluid. When the fluid comprises a peroxide based tooth whitening agent, the dispensed fluid pH is increased by the electrical charge which improves the efficacy of the whitener. In one embodiment, the implement is a modular system including a powered base unit and one or more interchangeable cartridges each having a reservoir containing an oral care fluid.

An applicator device (1) for applying a composition to an end of a pipe. The applicator device comprises an applicator head (3), the applicator head having a cavity (9) with an opening into which the end of the pipe can be inserted. The applicator head comprises at least one brush (10) and at least one aperture (12) for delivering the composition into the cavity, each brush having bristles which extend into the cavity (9) to wipe against the end of the pipe, each aperture being closer to the opening of the cavity than to a base of the cavity. There is further provided an applicator device (1) comprising a supplementary brush for wiping the composition over an internal surface of the pipe, a container (60) of flux composition for connecting to the applicator device, and a method of applying a composition to an end of a pipe.

A method of delivering a glutinous substance to a workpiece from an end-effector comprises using the end-effector to rotate a brush relative to the workpiece about a rotational axis. The method also comprises, while rotating the brush relative to the workpiece about the rotational axis, urging the glutinous substance from the end-effector through a channel of a body of the brush from an axial inlet of the channel to an outlet of the channel, into contact with a thatch of bristles of the brush. Additionally, the method comprises using the end-effector to position the brush relative to the workpiece such that the glutinous substance in contact with the thatch is delivered onto at least a first surface and a third surface of the workpiece.

A pump assembly for a dental cleaning appliance includes a fluid chamber, a piston, and a drive. Magnets, connected respectively to the piston and the drive, enable the drive to couple to the piston and move it within the fluid chamber to draw fluid into the fluid chamber. A stop prevents the piston from being pulled beyond a stop position so that through continued actuation of the drive the magnets separate to allow a spring to push the piston away from the stop position to urge a burst of fluid from the fluid chamber.

A hand attachable animal washing apparatus, attachable upon the hand of a user, enables singlehanded control of waterflow and application of water into the coat of an animal. Control of waterflow though a molded body member is enabled by operation of a compressible portion disposed to control a valve assembly disposed interiorly within the molded body member. A proximal arced edge is disposed projected rearwardly from the molded body member and curved downward to direct waterflow away from a user operating the device, particularly when the device is elevated above a user, as when washing a large animal such as a horse, for example. A user may thereby control and apply water to an animal with one hand while securing and comforting the animal with the other hand.

A surface attachable washing apparatus enables easy control of water flow through a molded body member. A valve assembly, disposed interiorly within the body member, is actuated by simple depression of an overlying portion of an obverse surface of the molded body member, to toggle a valve assembly between each of a closed position and an open position. Water flow is therefore controllable by manual pressure to alternately emit and prevent water flow sprayed through each of a plurality of outlets. At least one suction cup enables selective positioning of the molded body member upon a surface distally situated relative to an existing water outlet to which the apparatus is connected. A user may therefore position the apparatus at a desired height in the bath room, for example, to correspond with a child who can then easily control of the water flow during bath time.

This disclosure relates to a device to break down biofilm and selectively supply liquid in the mouth. An examples head for a dental tool includes body, a front surface, and a back surface. The body define a chamber to contain a substance and a vacuum channel separate from the chamber to fluidly connect to a vacuum supply. The front surface includes a brush plate with brush teeth. The brush plate defines a wall of the chamber. The front surface also defines distribution holes in fluid connection with the chamber. The back surface is opposite the front surface. The back surface defines a vacuum port in fluid connection with the vacuum channel.
