Title: TOOTHBRUSH BRISTLE
Abstract:
The invention concerns a bristle (1) which can be used in a brush (4), a paintbrush or the like, and in particular in a toothbrush. The bristle (1) is made from plastics and preferably has a circular cross-sectional area. Viewed in cross section, the bristle (1) has two regions (2, 3) displaying different properties. These regions (2, 3) are not disposed concentric with each other, such that the bristle (1) bends along its longitudinal axis. This bending improves the cleaning effect of the brush (4).
