An all-in-one oral care system that includes a brush, a main body, a top cover, a bottom cover, an interdental brush, and a toothpaste cartridge. All major components are designed to be detachable and replaceable using attachment mechanisms built into each part. The oral care system utilizes a manual actuator to force toothpaste from the main body into the toothbrush head and onto the bristles when depressed. When released, the actuator creates a vacuum force that draws toothpaste from the cartridge into the main body. The vacuum force draws a plunger in the cartridge upwards to move the toothpaste to the main body.

Hairbrushes that dispense liquid are disclosed herein. In some embodiments, a hairbrush system includes a brush body, a bristle support layer, and a liquid container configured to store a liquid. The bristle support layer includes a plurality of apertures and supports a plurality of bristles extending outwardly from the brush head. In some embodiments, the hairbrush is configured to transfer the liquid from the liquid container into a chamber defined by the brush body and the bristle support layer. In operation, the hairbrush transfers the liquid from the chamber through the plurality of apertures and into the bristles when the bristle support layer is compressed.

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.

A liquid dispenser for discharging liquids, in particular in rod shape. The liquid dispenser has a liquid store for receiving liquid prior to discharge, and a discharge opening for discharging the liquid. The liquid dispenser has a pumping device having an actuating surface for manual actuation, by which liquid is conveyed from the liquid store to the discharge opening. The liquid store is provided within an exchangeable container unit, couplable to a main unit including the pumping device (62) and the discharge opening, and is uncouplable therefrom. For the exchangeable coupling of the container unit to the main unit is provided a coupling device, by which the container unit, by pressing against the main unit, is alternately couplable thereto and releasable therefrom. The coupling device possesses two coupling members, wherein one coupling member is provided on the container unit and one coupling member on the main unit.

A dental solution dispenser includes a body having a first end, a second end, and including a front housing at the first end, a twist back at the second end, and a grip that interposes the front housing and the twist back. An applicator tip is coupled to the body at the first end, and an ampoule assembly is positioned within the body and includes an ampoule sealed at one end with a frangible seal and defining a fluid chamber for storing a dental solution. A mandrel extends longitudinally within the body and provides a piercing member. The twist back is rotatable relative to the grip to pierce the frangible seal with the piercing member. A trigger is coupled to the body and pivotable between an engaged position, where the trigger engages the ampoule assembly, and a disengaged position, where the trigger disengages the ampoule assembly.

A cleaning device includes a bristle bundle and a handle. The handle has a tubular structure and includes a straight part and a bent part, and the bent part is located at the end of the straight part. The bristle bundle is detachably placed in the tubular structure of the handle, and one end of the bristle bundle extends out of the bent part.

An oral care system includes a dispenser comprising a product tube having a reservoir containing an oral care material and an outlet. In one embodiment, the dispenser may be configured for detachable coupling to a toothbrush. A compression device engages the product tube and pressurizes the tube contents. The oral care material may be dispensed by actuating a valve fluidly coupled to the reservoir and outlet. In one embodiment, actuating the valve includes a flow orifice movable into and out of a flow path through the dispenser. Oral care material may be dispensed by positioning the orifice in the flow path in which the pressurized material flows outwards the product tube. To stop the flow of oral care material, the orifice is removed from the flow path which blocks the path. An operating button is provided in one embodiment to change position of the flow orifice.
