    • A toothbrush which comprises a brush main body (10) made of a synthetic resin and having a bristle base (12) and bristles (2) made of a thermoplastic resin which have been fusion-bonded to the bristle base to constitute a bristled part, wherein the bristles (2) constituting the bristled part at least partly comprise: tapered bristles which are bristles having split free ends, the split free ends having been tapered beforehand; tapered bristles which have a sectional shape having a core-sheath structure or sea-island structure; or tapered bristles in each of which a core bristle comprising a core or island part has been formed beforehand so as to be exposed at the free end. The toothbrush has excellent suitability for bristle insertion into narrow parts, e.g., the gaps between neighboring teeth and gaps between the teeth and the gums. It is highly effective in removing dental plaque and cleaning the teeth. It is highly easy to use in the oral cavity. It further has a highly attractive appearance.
    • 一种牙刷,其包括由合成树脂制成的刷子主体(10),具有刷毛基部(12)和由热塑性树脂制成的刷毛(2),所述刷毛基底已经熔接到所述刷毛基座上以构成刷毛部分, 其中构成刷毛部分的刷毛(2)至少部分地包括:具有分叉自由端的刷毛的锥形刷毛,分离的自由端预先已经变细; 具有芯鞘结构或海岛结构的截面形状的锥形刷毛; 或锥形刷毛,其中预先形成包括芯或岛部分的芯毛,以便在自由端露出。 牙刷具有优异的适用于将刷毛插入狭窄部分中,例如相邻牙齿之间的间隙和牙齿与牙龈之间的间隙。 它能有效去除牙菌斑并清洁牙齿。 它在口腔中非常容易使用。 它还具有非常有吸引力的外观。

Date Mar. 20, 1997A toothbrush has a brush head and plastic bristles, optionally combined into bundles, fixed thereto and whereof at least some bristles have a profile on their circumferential surface. In order in the case of unchanged strength characteristics of the bristles to obtain an increased cleaning and massaging action, the bristles have a helix as the profile. The bristles can comprise a core and at least one helix running over the circumferential surface. For the manufacture of the toothbrush it is possible to extrude and then twist a profiled monofilament or a monofilament with axially parallel ribs and then fix the twist. It is also possible to co-extrude a monofilament made from one plastic with ribs made from a plastic having other characteristics running over its circumferential surface, followed by the twisting of the co-extruded composite and the fixing of the twist.
