The invention also relates to a process of manufacture thereof, using a rotomolding oven to fuse the plastic cup member and plastic ear member to the rubber envelope by melting the envelope material while maintaining the cup member and ear member solid, and by thereafter intermelding the solid ear and cup member with the liquid rubber envelope compound.
