Abstract
A unitarily molded toothbrush is provided including a head with bristles integrally molded therewith, a handle and a neck, all being formed of an identical plastic material, preferably a polyolefin resin, having a Melt Index no lower than 6 g/10 min. At least one recess is formed with respective opening in an undersurface of the handle of the toothbrush. In alternative embodiments, recesses and their openings can also be found in the neck and head. These embodiments may include a beam flanked by the recess openings longitudinally traversing the length of the handle, and optionally also traversing the neck and head. Cross members may be formed orthogonal to the beam to strengthen the structure. Also provided is a kit for dental hygiene which includes the unitarily molded toothbrush in combination with a dentifrice to improve the delivery of flavor or a therapeutically active substance such as a source of fluoride.
