Abstract
A hygienic toothbrush wherein the brush portion is carried in contact with a sterilizing solution after use. To avoid spillage, the sterilizing solution is contained in a small, replaceable, plastic container which is inserted into the back of the brush and perforated to release a small quantity of solution into a chamber in communication with the brush head during storage and transport thereof. Should damage occur to the brush and its carrier during the storage phase, only minimal spillage of the sterilizing liquid can occur. The toothbrush is made foldable to provide a small size for storage.
