A cosmetic brush is disclosed. The cosmetic brush of the present disclosure includes: a brush grip provided as a grip for a user; a brush coupler coupled to the brush grip; a brush hair part coupled to the brush coupler and having hairs; and a connection fixer having a first side coupled to the brush grip and a second side supporting the hairs, and configured to surround the brush coupler, in which the brush grip includes a grip body provided as a grip for a user, and a connector unit having a first side coupled to the grip body and a second side to which the brush coupler is detachably coupled, the brush coupler includes a first coupler section and a second coupler section configured to be detachably coupled to each other, and the brush hair part is detachably coupled to the brush coupler.

A replacement toothbrush head includes a tubular sleeve having a brush at one end and a drive shaft receptacle at the opposite end. The receptacle extends into the sleeve from a mouth at a tube end to a shoulder spaced from the mouth within the tube. A coupling member is inserted into the receptacle, and a spring clip is positioned between the receptacle and the coupling member, the spring clip having a base positioned between the shoulder and the distal end of the coupling member and a pair of spring arms overlying the sidewall of the coupling member. At least one of the spring arms engages a flexible region of the coupling member such that the flexible region flexes to engage a drive shaft inserted into the coupling member and retain the replacement head on the drive shaft.

The brush for the application of cosmetic products comprises a housing seat for housing at least an application body having a plurality of spreading elements to spread a cosmetic product on a user, in which the housing seat comprises at least two concave portions defining on the application body at least two application faces of the cosmetic product allowing to reproduce the pattern of the user's facial features such as the nose of the users and/or the mandibular profile.

A cleaning tool for cleaning accumulated charred food material on grill grates. The cleaning tool is of a two-prong tuning fork shape that has a handle and a cleaning head. A shaft extends between the two prongs of the cleaning head. Several cleaning discs are slidably provided between the two prongs over the shaft wherein two adjacent cleaning discs are separated by one or more spacer discs. the cleaning discs scrap the accumulated material from the grill bars.

The present invention relates to a multifunctional scrubbing device for easily and comfortably scrubbing difficult to reach areas. The device includes an extensible handle having locking pins for retracting and extending the handle, a scrub head having scouring element or pad in the form of bristles or sponge and of different textures for scrubbing. The handle is pivotally coupled to the scrub head using a pivot lock to allow the handle to pivotally move relative to the scrub head. The handle has an ergonomic grip for easy handling and a ring hook for hanging the device on a wall-mounted hook when the device is not use. In one embodiment, the device has one or more cleaning solution storage reservoirs disposed in the scrub head for dispensing cleaning or other solutions on the scouring element or pad.

A finger toothbrush for brushing the teeth of a patient comprises a soft, for example rubbery, flexible outer housing defining an elongated rubbery housing internal volume, with the flexible outer housing having an outside surface and an internal surface. The flexible outer housing has a proximal end and a distal end. A finger receiving member defines an internal volume for receiving a finger of an individual. The finger receiving member is more rigid than the soft flexible outer housing and is positioned within or incorporated into the outer housing layer, for example, as coil or wire. The finger receiving member is positioned with its outer surface being positioned radially inwardly from the outer surface of the rubbery flexible outer housing. The rubbery flexible outer housing is made of a material compressible enough to absorb the pressure of teeth biting down against the finger receiving member without the teeth being damaged. A cluster of scrubbing surfaces extend from the outer surface of the rubbery flexible outer housing.
