发明名称 A TOOTHBRUSH
摘要 <p>A toothbrush having a handle (4) and a head (1), the head (1) being of length L and having longitudinal and transverse axes, the head (1) having a bristle-bearing surface (7) with a plurality of tufts (6) extending therefrom, wherein the tufts (6) are arranged in a plurality of groups N, which are separated from each other by a transverse gap (8) of from 1.3 mm to 5 mm, the distance between tufts (6) within a group being less than 1.3 mm, and wherein at least 50 % of the tufts (6) are characterized by there being no other tuft (6) within 1.3 mm, measured along a line parallel to the transverse axis, for at least 50 % of the width of the tuft (6). Preferably, each group is in the form of a crescent shaped array and tufts (6) are generally perpendicular to the toothbrush head (1). The arrangement allows for independent movement of bristle tufts (6), particularly whilst using the Bass technique for toothbrushing, yet maintains a high density of tufts (6) on the toothbrush head (1).</p>
