  • Patent number: 4884311
    Abstract: This invention relates to the field of oral hygiene. One embodiment comprises a spring clamp adapted for removable affixation to the bristles of a toothbrush, after it has been used, in a crucial region proximal the free ends of the brush bristles. A discovery and identification of the crucial area is claimed. A preferred embodiment is so designed that the impact area of the clamp on the brush is approximately 1/4 distance down from the free ends of the bristles. The clamp causes the bristles to be closely juxtaposed throughout the clamped area, while the bristles above the clamped area are permitted to flare outward, while the lower portion of the bristles below the clamp line form into a wedge-like configurtation, both of which shapes tend to move in opposite direction during the brushing action providing a resilient base of support for the flared upper portion.
