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