Bristles have integrally formed flattened and extended distal ends which terminate in distal outer edges for cleaning teeth. The bristles are arranged in toothbrushes with edges aligned with a longitudinal direction of the toothbrush and with the edged bristles positioned along lateral areas of the toothbrush and extending angularly outward therefrom.

Paint brush bristles formed from polybutylene-1,4-terephthalate exhibiting superior bend recovery and initial modulus of elasticity in flex as well as in paint solvents, satisfactory temperature dependence of modulus and amenability to flagging and tipping.

The invention is directed to bristles for a hairbrush, in particular for employment in an appliance for personal use as, for example, a curling iron, a curling brush, a hair dryer or the like, including a bristle base (3) and a bristle head (5). In this arrangement, the bristle base (3) is adapted to be fastened to a bristle supporting structure (7). The bristles (1) include at least two sections (9, 11) with cross-sectional areas of different sizes. A section with an increased cross-sectional a...

A system and method removes material from the wall of a passage, such as a vein or artery, in a patient's body with a series of bristles that are rotated. The bristles are part of a sweep catheter having a proximal end and a distal end with a tip thereon. Bristles next to the tip extend out from the distal end a shorter distance than the bristles further from the tip. The bristles, which have smaller bristles or sub-bristles thereon, are inclined away from the tip as they extend out from the dis...

A thermoplastic monofilament for bristles which are exposed to excessive moisture during use, consists of a polymer mixture of at least one polyamide (PA) and at least one thermoplastic polyester (PE) whose mixing ratio is selected according to the technical, functional properties decisive for the use of the bristle as well as in dependence on the ambient conditions at the location of use decisive for the function of the bristle.

A system and method for protecting bristles that includes a sleeve sized and shaped to be slideably received over a handle attached to the bristles, the sleeve formed of breathable material to facilitate drying of the bristles, and the sleeve formed of rigid material to support the handle and the bristles in a vertical orientation and to protect the bristles, the sleeve formed of a length sufficient to cover the bristles, and to cover at least a portion of the handle. In accordance with a method...

In order to apply mascara and comb they eyelashes, the invention proposes carrying out a selective, clean and adaptable cutting of the bristles twisted along a core by selecting some of the bristles located, along the wire, in angular sectors of adjustable amplitude and by continuously cutting the bristles thus selected at a predetermined height. The implementing guiding module has a guiding inlet head (69a) and a cylindrical tube body (69c), the head being for bristles remain curved. The cuttin...

A collapsible hair or massage brush has a body divided into two flat, superposed members in the form of slotted plates or frames which are limitedly relatively shiftable in a predetermined direction to swing a multiplicity of bristle carriers, normally retracted into the body, through substantially 90.degree. into a working position in which their bristles project perpendicularly from one of the body surfaces. The bristle carriers are journaled in one of the members by pivotal axles transverse t...

A brush is disclosed which comprises a housing; a bristle-bearing head rotatably mounted in said housing; driven means, preferably in the form of an impeller, connected to the head for rotating the head in response to fluid flow; motor means connected to the head for rotating the head, and fluid responsive control means for energizing the motor means as a function of fluid flow.

A brush with retractable bristles is constructed which comprises an enclosure which has apertures through the top surface, a member which holds the bristles and which is movable upward and downward within the enclosure, bristles one end of which are held in the bristle holding member and the other end of which are aligned with the apertures, means for moving the bristle holding member from a position whereby the bristles extend out through the apertures to a position whereby the bristles are sub...
