The oral care implement (100) comprises a handle (120); a head (110) coupled to the handle (120); at least one bristle tuft extending from the head, the at least one bristle tuft comprises at least one multi-component bristle (200) comprising coextruded core (210) and sheath components (220), the sheath component (220) surrounding a first portion (215) of the core component (210), and a second portion (216) of the core component (210) protruding from the sheath component (220) at a tip portion (230) of the multi-component bristle (200); the sheath component (220) comprises a first plastic and a first oral care additive; the core component (210) comprises a second plastic and a second oral care additive, wherein the first oral care additive is different than the second oral care additive.

A fluid dispensing scrubber includes a shaft having a first end and a second end; a fluid inlet configured to receive a first fluid from an external source; a reservoir configured to store a second fluid; a valve assembly configured to selectively mix the first fluid and the second fluid; a scrubbing head supported adjacent the first end of the shaft, the scrubbing head including a brush and a motor operable to rotate the brush; a battery pack supported adjacent the second end, the battery pack operable to provide power to the motor; and a dispensing nozzle configured to selectively dispense one or both of the first fluid and the second fluid, the nozzle supported on an exterior surface of the scrubbing head.

An animal toothbrush for brushing an animal's teeth without requiring the external application of a tooth cleaning substance to the toothbrush includes an elongate handle with a head mounted to a first end of the elongate handle. The head is impregnated with a tooth cleaning substance and has protrusions which facilitate abrading the animal's teeth. A method of using the animal toothbrush is also disclosed.

A cosmetic applicator capable of stably applying an application liquid without clogging the application member composed of a brush tip with particles contained in the application liquid is provided. The front barrel 3 is made of a transparent material and the tip of the brush tip is arranged to protrude from the front barrel through the front end opening 3b of the front barrel 3 while the brush tip is mounted inside the front barrel. A clearance is formed between the front end opening of the front barrel and the brush tip, which allows the brush tip in the front barrel to also be deflected and deformed along with the deflection and deformation of the brush tip based on the application operation of the application liquid by the brush tip.
