A dental dispensing tip includes a body having a first body end, a second body end, and a fluid passageway extending between the first and second body ends. A brush cup is provided at the second body end and has a brush barrel defined therein. A brush applicator is secured within the brush barrel and includes a plurality of bristles, wherein a first end of the brush applicator is received within the brush barrel and a second end of the brush applicator extends out of the brush barrel. A delivery cannula is in fluid communication with the fluid passageway and has a bent end entering the plurality of bristles at an intermediate location between the first and second ends to deliver the dental solution to the plurality of bristles.

A brushroll dowel for a vacuum cleaner has a bristle stiffener protruding from a brush dowel. A plurality of stiffened bristles protrude from the brush dowel adjacent to the bristle stiffener, and a plurality of unstiffened bristles also protrude from the brush dowel and are non-adjacent to the bristle stiffener.

A brushroll dowel for a vacuum cleaner having bristle stiffeners protruding from a brush dowel. The brushroll can be made using an injection molding process, with the bristle stiffeners integrally molded with the brush dowel and a plurality of stiffened bristles protruding from the brush dowel adjacent to the bristle stiffeners.

A method of tufting, with a tufting tool, a brushroll dowel for a vacuum cleaner having a bristle stiffener protruding from the dowel and a bristle hole adjacent the bristle stiffener. The tufting tool includes a notch. The method provides a brushroll with bristles tufted into the bristle hole adjacent the bristle stiffener. A brushroll for a vacuum cleaner can be made using an injection molding process, with bristle stiffeners integrally molded with the dowel and a plurality of stiffened bristles protruding from the brush dowel adjacent to the bristle stiffeners.

A tufting tool for tufting and fastening clusters of bristles in bristle holes in a contoured surface of or oblique holes in a brush body. The tufting tool has a tool head displaceable along the tufting axis between a receiving and a tufting position. The tool head has two guide jaws which are displaceable relative to each other during displacement of the tool head. To relatively displace the guide jaws, the tool has a reversing lever connected to the tool head and a deflecting guide for the reversing lever, arranged at an angle of deflection with respect to the tufting axis. The guide jaws are coupled together via the reversing lever in such a manner and the reversing lever is guided such that an adjustment of the tool head into the tufting position advances one guide jaw in the tufting direction and retracts the other guide jaw counter to the tufting direction.

A toothbrush includes a handle and a bristle-carrying head part, which are connected to each other by a neck part, the head part having a multiplicity of tufts of bristles consisting of bristles. An anchor is oriented at right angles to the longitudinal axis. Two or more tufts of bristles have a bristle tuft half with bristle ends standing up higher in relation to the bristle ends of the other bristle tuft half.

A tuft picker for a tuft-picking device has a working surface having a tuft-picking notch with a depth, a width, and an opening. First and second projections reduce the opening of the notch versus an inner width. At least one top of the first and/or second projection is located off-site the working surface of the tuft picker and inside of the notch. A distance from the at least one top to the working surface of the tuft picker is in the range of from 0.05 mm to 0.5 mm, and an angle between the working surface of the tuft picker and a line of reflection symmetry crossing the at least one top is from 1 to 45.

The invention concerns a toothbrush with a handle and a bristle-carrying head part, which are connected to each other by a neck part, the head part having a multiplicity of tufts of bristles consisting of bristles. An anchor is oriented at right angles to the longitudinal axis. Two or more tufts of bristles have a bristle tuft half with bristle ends standing up higher in relation to the bristle ends of the other bristle tuft half.
