    摘要： An oral care implement having a head with a plurality of cleaning elements coupled thereto and extending therefrom. In the exemplified embodiment, the cleaning elements have a plurality of bristle tufts each including a plurality of bristle filaments. In one aspect, the oral care implement may include a first bristle tuft having inner and outer filaments with the outer filaments being taller than the inner filaments and a second bristle tuft having inner and outer filaments with the outer filaments being shorter than the inner filaments. The first bristle tufts may be arranged on the head in a position so as to surround the second bristle tufts, or the second bristle tufts may be arranged on the head in a position so as to surround the first bristle tufts. Distal ends of the first and second bristle tufts may be angled.

    摘要： A method of providing an insertion guidance tip at a distal end of an interdental brush, use of a first set of filaments and a second set of filaments in an interdental brush, and an interdental brush comprising a first set of filaments arranged along a first longitudinal sub-length and having a first filament diameter, and a second set of filaments arranged along a second longitudinal sub-length and having a second filament diameter, wherein the second filament diameter is smaller than the first filament diameter, wherein the second longitudinal sub-length is positioned at the distal end of the interdental brush, and wherein the second sub-length has a length along the longitudinal direction being less than 15% of a longitudinal extension of the brush portion and extending along less than three twists of a core member.

    摘要： A personal care implement has a handle including an elongate body having opposed first and second sides extending longitudinally between opposed proximal and distal ends, and first bristles attached fixedly to the elongate body. The first bristles form a scrub brush extending longitudinally of the elongate body between the proximal and distal ends, transversely of the elongate body between the first and second, and outward from the elongate body to a scrub-brushing extremity. An elongate member extends outward longitudinally from the distal end to a toothbrush head assembly. The toothbrush head assembly is of a first size to facilitate reception of the toothbrush head assembly in a mouth of a user for toothbrushing. The handle is of a second size larger than the first size to facilitate grasping and holding the handle by one hand of the user.
