摘要： An extrusion blow molded plastic container includes a main body portion and a finish portion that defines an opening. The finish portion has an upper surface and an outer surface on which a snap bead is defined. In order to prevent saddling of the upper surface, a plurality of grooves is defined in the outer surface, each of the grooves passing through the snap bead. In addition, the main body portion has an outer surface that defines a substantially rectangular shape with rounded corners when viewed in transverse cross-section. The outer surface of the finish portion also has a substantially rectangular shape with rounded corners when viewed in transverse cross-section. The shape of the finish portion when viewed in transverse cross-section is smaller than the shape of the main body portion. A ledge is defined between the outer surface of the main body portion and the outer surface of the finish portion. The ledge has a first width, adjacent to one of the rounded corners of the finish portion, which is greater than a second width that is not adjacent to one of the rounded corners of the finish portion.

摘要： A pivot casting component (210) used in an apparatus for extrusion blow molding polyethylene teraphthalate ("PET") is disclosed. The pivot casting is designed to provide increased strength and increased reliability over prior components with the blow mold clamping linkage system. Prior art pivot elements were designed and fabricated from separate elements such that weak points, and stress concentration points were created. Such weak points resulted in the pivot element being a weak component in the blow mold clamping linkage system. The inventive pivot casting is cast as a single component from higher strength materials, with an improved geometry to increase component strength, durability and overalll system reliability. Ina preferred embodiment, the air side pivot casting is fomred from 80-55-06 ductile iron resulting in a 40% increase in tensile strenth over prior pivot components.

摘要： A cam follower slide component used in an apparatus for extrusion blow molding polyethylene teraphthalate is disclosed. The cam follower slide component is designed to include disc springs (330) positioned about a spindle that is in turn located along the slide direction of the cam follower. With the inclusion of disc springs, the cam follower slide is capable of absorbing certain excessive forces within the blow mold clamping linkage system that may develop during irregular blow mold process conditions. In a preferred embodiment, the cam follower slide component includes the ability to adjust the spring force of the disc springs to allow for a variation in allowable excess system linkage forces.
