A method for producing a plastic part having a first component and a second component connected to the first component. The method includes molding a temporary connection between the first component and a preliminary second component, coating at least a surface region of the first component, separating the first and preliminary second component, and then molding the second component to the first component. The plastic part can be an injection molded part and the components of the plastic part can be made using the same or different plastics.

The invention is directed to a bristle for a toothbrush, particularly for an electric toothbrush, and to a method for its manufacture. The bristle is manufactured from a monofilament () made of plastic. The bristle has in its cross section at least two zones () and at least one point of preferred breaking.

The invention is directed to a blood pressure monitoring device comprising a central parts mounting module and to a method of manufacturing this parts mounting module. According to the invention fluid channels are produced by gas injection into the interior of the parts mounting module, the walls bounding the fluid channels being completely formed by the material of the parts mounting module. The injection of gas continues for as long as a core of the parts mounting module is still in the liquid phase in the area of the fluid channel, whilst an outer area surrounding the core has already solidified, so that the pressure fluid expels the liquid core area, producing a tubular fluid channel.

The invention is directed to a bristle ( ) suitable for use in a brush ( ) or the like, and in particular in a toothbrush. The bristle ( ) is made of a plastic material and includes preferably a circular area of cross-section. When viewed in cross-section, the bristle ( ) includes two sections ( ) with different properties. These sections ( ) are not in concentric relative arrangement. As a result, the bristle ( ) curves along its longitudinal axis. The curvature produces an improved cleaning action of the brush ( ).

Bristle for a toothbrush

The invention is based on the discovery that flocked or textured materials (e.g., for use as dental floss, or toothbrush bristles) can be manufactured without using adhesives to secure the short fibers or texture particles to the base material, or substrate. The flocked or textured materials are formed by thermally or chemically softening a preformed substrate (e.g., sheets, fibers, or filaments made of TEFLON&reg; fibers, KEVLAR&reg; fibers, cotton, polyester, polyethylene, or other plastic), then treating the softened substrate with short fibers or texture particles. Alternatively, the short fibers or texture particles can be applied during the formation of the substrate (e.g., in an extrusion, melt-blowing, die casting, weaving, or drawing process).

Method of manufacturing a textured toothbrush bristle

The invention is directed to a bristle (,) suitable for use in a brush (,) or the like, and in particular in a toothbrush. The bristle (,) is made of a plastic material and includes preferably a circular area of cross-section. When viewed in cross-section, the bristle (,) includes two sections (,) with different properties. These sections (,) are not in concentric relative arrangement. As a result, the bristle (,) curves along its longitudinal axis. The curvature produces an improved cleaning action of the brush (,).

The invention is directed to a bristle (12) for a toothbrush, in particular for an electric toothbrush, which is made of plastic and includes several filaments (13, 14, 15) joined together. The filaments (13, 14, 15) are wound or braided and joined together as a result of the action of chemical agents. This results in a firm bond between the filaments (13, 14, 15), and any cavities between the filaments (13, 14, 15) are reliably avoided. Overall, a toothbrush results which, in addition to having a high cleaning effect, offers bacteria or other germs no possibility of infiltration.

The invention is directed to a bristle (1) for a toothbrush, in particular for an electric toothbrush, which is comprised of a monofilament (2) made of plastic. The monofilament (2) is of a non-circular cross-section, is twisted about its longitudinal axis, and is fixed as a result of the action of chemical agents. In this manner, the bristle (1) is provided with a three-dimensionally structured surface which effects an improved cleaning action, in particular with regard to the removal of plaque.
