Methods for Making Safety Toothbrushes

摘要

A method of making safety toothbrushes is disclosed. The toothbrush apparatus detailed herein employs a composite head made from a rigid inner polymer material and a softer thermoplastic material surrounding the inner material. The softer material provides safety for prison toothbrush applications as well as elderly and patient care where care givers may brush the teeth of the patient. The solution is importantly devoid of glue due to bonding that occurs during the mold curing process.
