Abstract: A system for processing a simplified plastic container (C) that is to be filled with a hot product includes the step of blow-molding parison to form a container body, where the container body has a neck, a base, a side surface relatively free of structural geometry that surrounds an interior of the container body and, prior to being filled with the hot product, a projection (12) extending from the container body. After the container body is filled with a hot product in a production line, the neck of the filled container body is capped with a cap and then, the container body is cooled. During the cooling operation, the hot product is contracted so that the projection extending from the container can be pushed (P) into the container body like a traditional push-up so that the resultant, filled and cooled container body is relatively free of structural geometry.

Abstract: A device for fracturing a defective preform for use in blowmolding is claimed. The preform has head end and a tail end and the device comprises a tube with walls defining a cavity for accepting the defective preform while the defective preform is on a core of an injection molding apparatus, an attachment element that attaches the tube to the injection molding apparatus, and locates the tube relative to the core; and a percussion instrument that contacts and breaks the defective preform at the tail end of the preform.
