Single-use toothbrush
Abstract
Abstract A single-use toothbrush of molded plastic material, composed of a plurality of cylindrical clusters of bristles integrally molded with the body of the toothbrush and coated with a thin layer of dentifrice composition which is sprayed onto the bristles in an amount adequate for a single brushing only. Each cluster is composed of four bristles of approximately triangular section and is formed by bristles projecting from a cylindrical base of small depth which is bisected by a pair of rectangularly displaced diametral slots which define the inner surfaces of the bristles while the lateral surfaces of the latter are coincident with the periphery of the base. The size of the clusters and their spacing from each other impart an optimum degree of flexibility to the bristles.
