Abstract
Abstract A cushioned handle structure for use in personal care appliances including two plastic understructure halves having outer and inner surfaces, each half having a plurality of holes running between the two surfaces. An elastomeric material is integrally formed as an overlay in contact with the outer surface and is integrally continued as plugs in the holes so that the overlay is held in position in contact with the outer surface by the plugs. The holes may be undercut proximate to the inner surfaces or be continued as channels on the inner surfaces to provide greater integrity.
