Abstract
A unitary two component article for personal hygiene, such as a toothbrush, wherein the same is formed by injection molding of two differing plastic materials. The plastics do not adhesively or chemically bond to each other. The two differing plastic parts of the toothbrush are mechanically connected, such as by interfitting portions of the two plastic components or by shrinking one plastic component about the other.
