A cartridge and method to authorize and adjust the operation of an oral care appliance are disclosed. The oral care appliance along with the cartridge may be used for cleaning, whitening, removing plaque, or in other general oral care applications for providing oral care hygiene.

A fluid dispensing brush for applying a fluid to hair includes a plurality of bristles that is coupled to and extends from a housing. The bristles are tubular and are in fluidic communication with an interior space defined by the housing. Each of a plurality of holes is positioned in a respective bristle. A handle extends from a first end of the housing. A channel extends through the handle to the housing. A pump is positioned in the channel proximate to the housing and is in fluidic communication with the interior space. A reservoir is selectively insertable into the channel so that a nozzle of the reservoir sealably couples to an inlet of the pump. The pump is configured to selectively pump a fluid that is positioned in the reservoir through the interior space and the bristles to exit through the holes to apply the fluid to the hair.

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.

A cosmetic container has a shell, a pressing member, a containing device, a joining sleeve, a brushing device, a positioning sleeve, and a cap. The pressing member and the containing device are disposed in the shell. The containing device is located below the pressing member. The joining sleeve is disposed on a bottom opening of the shell. The brushing device, the positioning sleeve, and the cap are disposed on the joining sleeve. The brushing device abuts against and communicates with the containing device. The positioning sleeve abuts against the brushing device. Bristles of the brushing device extend out of the positioning sleeve. The cap is disposed on the joining sleeve. Liquid fragrance in the containing device is sprayed to the bristles by the pressing member. The bristles can brush the skin of a user for applying the liquid fragrance to the skin of the user.

A droplet for delivering toothpaste to a user can be provided. The droplet can include a dissolvable outer membrane defining a volume with toothpaste inside the volume. The outer membrane can be formed from dissolvable film strip technology and include a tail or corner portion, which is configured to be embedded into the bristles of a toothbrush. In one aspect of this embodiment, the outer membrane of the droplet can form a pillow-like shape. The droplet further can include one or more extensions coupled to the outer surface of the outer membrane, where the one or more extensions can have a triangular shape, a barb shape or the like. In one aspect of this embodiment, the droplet further can include a logo, a cartoon character, a word or the like printed on the outer membrane. The plurality of extensions can form irregularities on the outer surface of the body section of the outer membrane.

The present disclosure provides a system including a handheld implement having a handle and a head. The system also includes a base having a basin, a pump, and a product container. The basin includes vertical walls forming mouth opening to an inner cavity that receives the head of the handheld implement. The product container includes a reservoir of product. The pump conveys the product from the reservoir to the inner cavity via at least one through-hole in the basin.

A system comprising an implement and dispenser containing a fluid detachably coupled to the implement. In one embodiment, the dispenser has a housing that includes a reservoir containing a fluid and an actuator for dispensing the fluid from the dispenser. The dispenser is at least partially located within the cavity of the handle. The housing of the dispenser has at least one protuberance that protrudes radially beyond an outer surface of the handle thereby forming a ridge that a user can grip to remove the dispenser from the cavity of the handle.

A cartridge and a base unit for use in an oral care appliance are disclosed. The cartridge includes a connection interface configured to form a detachable connection. The base unit is also configured to engage operatively with the cartridge to facilitate flow of an oral care composition from the cartridge into the oral care appliance.

A brush has a hollow body having a working surface, a reservoir for a fluid inside the body, a valve to dispense fluid contained in the reservoir through a nozzle onto a surface to be engaged by the working surface of the brush and an activation mechanism for the valve, further comprising on a side of the body opposite the working surface, an opening or window through which a fluid level in the reservoir can be observed.

A multi-compartmental container for storage and easy mixing of two or more materials, e.g., pastes, is disclosed. The container has a container portion that includes two or more compartments containing materials that need to be mixed. The container further includes an outlet nozzle provided at an operative top end of the container. The compartments of the container portion are in fluid communication with each other so that the contents of the compartments can inter-mix with each other, when the container is shaken manually, thereby providing a final product that is to be applied to a body part of a user.
