ABSTRACT:
The present invention is directed to an apparatus for blow molding a recessed lip in a molded article. The apparatus comprises two plates reciprocally movable toward and away from one another. A center ring member is fixedly and perpendicularly mounted on each plate. A mold half is mounted on each plate and is divided into two sections. One section is located on each side of the center ring member and is reciprocally movable toward and away from the center ring member. A first ring member is affixed to each said section in proximity to said center ring member and has a channel. A second ring member is reciprocally movable in said channel and engages the center ring member. The recessed lip is molded between said center ring member, the first ring member and the second ring member.
