PATENT APPLICATION by REINER KADER for REINFORCED PLASTIC CONTAINER AND PROCESS AND APPARATUS FOR MANUFACTURING SAME ABSTRACT OF THE DISCLOSURE A cylindrical, synthetic plastic container having reinforcing hoops permanently bonded around the ends of the container is manufactured in a single blow molding process. Half of the outer peripheral edge portion of each of two reinforcing hoops is positioned in a semi-cylindrical mold half to place the hoops in spaced, parallel, co-axial alignment. Thereafter, a tube of soft thermoplastic is extruded through the open central portions of the hoops until the end of the tube overlies a co-axially positioned pneumatic nozzle. The semi-cylindrical mold half with the hoops retained therein is moved into engagement with a mating, semi-cylindrical mold half to form a cylindrical mold. End plates are moved into engagement with the hoops from opposite ends of the cylindrical mold; and air under pressure is admitted through the nozzle to blow the walls of the tube of soft thermoplastic against the interior walls of the mold, the end plates and exposed circumferential portions of the reinforcing hoops to form a homogeneous bond with the hoops. - 1 -
