Embodiment Construction

[0013]With reference to FIG. 1 and FIG. 2, the present invention is a toothbrush having a bristle support head (10) and a bristle cluster (20).

[0014]The bristle support head (10) has a bristle surface (11). A bristle socket (12) is formed on the bristle surface (11) and has a wall. A fastening portion (13) is formed on an outer rim of the wall of the bristle socket (12) and may be an inwardly projecting ridge.

[0015]With reference to FIG. 3, the bristle cluster (20) has a fastening flange (21) and multiple bristles (22). The fastening flange (21) corresponds to and is mounted in the bristle socket (12) and may engage the fastening portion (13). The bristles are densely attached securely to the fastening flange (21), may be densely formed in the fastening flange (21) by injection molding and each bristle has an end adapted for cleaning teeth. The ends of the multiple bristles align to form a brushing surface (23). The brushing surface (23) may undulate with a wavelength equivalent to ...

Abstract

The present invention relates to a toothbrush having a bristle support head having a plurality of bristles densely implanted thereon and a brushing surface formed by ends of the bristles. The contact area between the bristle support head and teeth can be increased by virtue of the brushing surface. Reciprocal motion of the bristle support head maintains contact between the bristles and teeth so removes contaminants from inter-tooth spaces effectively and with improved efficiency.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a toothbrush, and more particularly to a toothbrush increasing contact area between the toothbrush and teeth for improved brushing efficiency.[0003]2. Description of Related Art[0004]With reference to FIG. 4, an existing toothbrush has a support head (90) having a mounting surface (91) formed thereon. A plurality of bristle holes (92) are formed on the mounting surface (91). Multiple tufts of bristles (93) are mounted respectively in the bristle holes separated by a gap.[0005]Since the tufts of bristles are spread over the mounting surface (91) of the support head (90), the gap is formed between the tufts. Hence, contact area between the bristles (93) and teeth is reduced and reduces brushing efficacy. As such, an improved toothbrush is required.SUMMARY OF THE INVENTION[0006]The main objective of the present invention is to provide a toothbrush increasing contact area of between bristles...
