A rotatable brush for animals is provided, having a longitudinal length and including a rotatable core portion with a plurality of bristles each having a first end connected to the core portion and a second free end located in a position radially outwardly of the first end with respect to a rotation axis of the brush. The brush includes at least one protective element rotationally fixedly connected to the core portion. The least one protective element is flexible and extends radially outwardly from the core portion. The protective element forms an outer hair guiding surface portion along the longitudinal length of the brush.

A toothbrush head comprises a head base and a head frame framing the head base. The head base comprises a substrate with multiple sockets for inserting bristles. The substrate has an outer frame, a central component, and two lateral components. The outer frame comprises a space, a front inner wall, a back inner wall, and two lateral inner walls. The central component is positioned in the space of the outer frame and links to the front inner wall and the back inner wall thereof. Each of the two lateral components is positioned between the central component and each of the two lateral inner walls and links to each of the two lateral inner walls with junctions, respectively, allowing the two lateral components to be rotatable. The toothbrush head helps users to brush the teeth with Bass method without injuring the gingiva, and keeps the toothbrush clean after brushing the teeth.

Cosmetic applicator comprising an application member having a base fixed to a support, this base extending along a longitudinal axis of the support, and an applicator part connected to the base, the applicator comprising a constraint element (30) attached to the application member and at least partially in contact with the latter, the constraint element (30) constraining the application member in such a way that the applicator part extends at least partially obliquely with respect to the axis of the support.

A floor cleaning machine that includes a disc broom that is rotatable about a rotation axis. The disc broom has a base body, bristles and a cover element. The base body has a circumferential outer edge. The bristles are attached at one end to the base body and extend away from the base body towards a sweeping plane that is perpendicular to the rotation axis. The cover element has a shell that is made of a flexible material. The shell extends away from the base body and towards the sweeping plane. The shell has an inner side, which faces an interior of the shell, and an outer side that faces an exterior of the shell. The shell envelopes the bristles perpendicularly to the rotation axis such that the bristles are disposed in the interior of the shell. A related disc broom and sweeping device are also provided.

The present invention relates to a paint-coating brush consisting of a rectangular flat body plate, a handle installed on a center of an upper surface of the body plate, and a plurality of bristles bundled on a lower surface of the body plate, wherein a front end portion of the said plate is bended downward to form a sharp R-shaped muzzle section. The procedures of using the paint-coating brush include: (A) dipping the plurality of bristles in paint; (B) using a front end (tip) portion of the body plate to contact a borderline of a target object and then coating towards a central part of the object being painted. However, the procedure of masking non-coating areas is not included.
