A dispensing paintbrush includes a handle, a brush head connected to the handle, and bristles attached to the brush head to apply a fluid to a surface. A coupler is attached to the handle and is configured to connect to a fluid source. A nozzle is attached to the coupler and is configured to dispense the fluid to the bristles. The nozzle extends within the bristles and terminates at a position from the brush head that is less than one half the length of the bristles.

An oral care system includes a main body, and a brush manually movable between a stowed and a deployed position. The brush includes a head, and bristles having respective first ends attached to the head and distal ends together defining a bristle surface for tooth cleaning in use. A toothpaste dispensing apparatus is carried by the main body and is configured to place toothpaste directly onto the bristle surface defined by the distal ends of the bristles when the brush is in the stowed position. The dispensing apparatus is configured to place toothpaste directly onto the bristle surface defined by the distal ends of the bristles without saturating the bristles at their first ends attached to the head. The toothpaste dispensing apparatus includes a port through which toothpaste is dispensed, and the port aligns with the bristles when the brush is at the stowed position.

A dental application device having a handle having a first end, a second end, and a containment chamber disposed within the handle. The device has a dental solution disposed within the containment chamber, a receiver tip coupled to the handle at the first end, a material passage within the receiver tip that forms a conduit between the first end and a receiving end, a frangible seal that separates the containment chamber from the material passage, and a piercing cannula in fluid communication with an applicator tip and having a distal piercing end extending toward the frangible seal. The piercing cannula is moveable between a first position and a second position. When in the first position, the piercing end is spaced apart from the frangible seal, and in the second position, the piercing end punctures the frangible seal and fluidly connects the dental solution with the applicator tip.

Embodiments described herein generally relate to a brush, a method of forming a brush, and a structure embodied in a machine readable medium used in a design process are provided. The brush includes a body and a channel configured to deliver a cleaning liquid through holes in the body. The method forms the brush using 3D printing. The structure provides details for making the brush. The disclosure herein allows a method of forming a brush that does not require the removal of active porogen.

An apparatus for dental irrigation may be provided to project fluid onto the surfaces of, and the interproximal spaces between, a user's teeth and gum-line. The apparatus may comprise two hollow U-shaped manifolds having orifices located on their interior faces used as fluid jets. The manifolds may be connected, at a central point of reflection, by a rotating inlet joint which supplies the fluid flow. When placed in the user's mouth, the apparatus may be designed to receive the top and bottom sets of teeth in each corresponding U-shaped manifold, with orifices configured to provide fluid jets aligned towards the lingual and buccal side of the teeth. The orifices may be staggered to provide staggered fluid flow. A user's teeth may be cleaned with a controlled fluid flow by moving the apparatus in a sweeping motion between each set of rear molars.

A liquid cosmetic material container includes a sleeve that includes a storage chamber that stores a liquid cosmetic material therein, a bead member that is disposed at a front end of the sleeve, has a through hole extending in an axial direction of the liquid cosmetic material container and configured to store a brush in the through hole, a relay core that is configured to connect the brush and the storage chamber, enter the brush, and send the liquid cosmetic material in the storage chamber to the brush, and a cap that is detachably attached to the sleeve. A rear portion of the through hole has a first cross sectional area, and a front portion of the through hole has a second cross sectional area which is smaller than the first cross sectional area.

An automatic mascara applicator apparatus for quick and even mascara application includes a housing having a housing inside. A battery cover is coupled to the housing. A battery is coupled to the battery cover. The battery is selectively engageable within the battery compartment. A motor is coupled to the housing within the housing inside and is in operational communication with the battery. The motor has a driveshaft. An activation button is coupled to the housing and is in operational communication with the motor. A brush is coupled to the motor. The brush comprises a hollow shaft filled with a mascara and a plurality of bristles. A distal end of the shaft is porous to release the mascara onto the plurality of bristles. A cap is coupled to the housing and is selectively engageable with the housing to cover the brush and the housing inside.

A hair and scalp treatment device that comprises a dispenser connected to a cartridge, wherein the cartridge comprises a formulation; a plurality of tips on the device, wherein the tips have at least one opening to dispense the formulation; and a controller configured to control the dispensing of the formulation through one or more tips individually.

A system for a paint brush including a brush head assembly and a reservoir assembly. The brush head assembly includes a brush head with bristles for painting a surface. In between the bristles is a roller brush in abutting contact with the bristles. The reservoir assembly includes a reservoir handle removably mounted to the brush head. The reservoir handle is filled with fresh paint to supply to the brush head to dispense. The reservoir handle is squeezed to allow the fresh paint to travel to the brush head and then soak the roller brush. The roller brush then allows for excess fresh paint to flow onto the bristles to allow users to paint the desired surface with the fresh paint on the bristles. The brush head further includes wheels that facilitate the maneuvering of the paint brush. Thereby allowing for painting to be done more efficiently.

A hair and scalp treatment device includes a dispenser connected to a cartridge, wherein the cartridge comprises a formulation; a plurality of tips on the device, wherein the tips have at least one opening to dispense the formulation and at least one LED that emits light in the visible color spectrum, wherein the at least one LED is located at the end of the tips; and a controller configured to individually turn on and off the LEDs from the plurality of tips.
