TOOTHBRUSH
Document Type and Number:
Japanese Patent JP3308227
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To effectively massage a border gum part by forming rubber-like bar brushes having a cross section form widening an outer peripheral side compared with the center side of a bristle implanting base at a part of the longitudinal border part of a bristle implanting base surface.
SOLUTION: At the longitudinal border part 10B of the bristle implanting base surface of a bristle-planting base 10 successively formed at the tip of a handle 11, rubber-like bar brushes 20 are implanted by proper number. The shape of the cross section of these brushes 20 is nearly a triangle widening an outer peripheral side compared with the center side of the base 10. Namely, one corner faces the side of a center and its opposed edge part is positioned nearly in parallel with the longitudinal border part 10b of the base 10. In addition, the brushes 20 is gradually tapered upward and its top part 21 is rounded. Thus, even a border gum part is reliably attained and the high massaging effect of the gums by its elastic sliding operation.
