Abstract
A toothbrush having a handle formed of a thermoplastic material with a glass transition temperature in the range of about 110.degree.-140.degree. F. The handle is heated to soften the plastic shaped to a desired configuration while pliable, then allowed to cool so as to retain the desired configuration when it hardens. The brush bristles may be detached from the handle when worn and replaced by a fresh set.
Claims7
A toothbrush comprising an elongated handle portion and a brush portion at one end of said handle portion, said handle portion being formed of thermo-plastic material having a glass transition temperature between approximately 110.degree. F. and 140.degree. F., whereby said handle portion may be heated to a temperature above its glass transition temperature, molded to a desired shape by manual manipulation while in a pliable state, then cooled to a temperature below its glass transition temperature, thereby rigidly fixing said handle portion in the desired shape.
