20090159556CONTAINER BASE STRUCTURE RESPONSIVE TO VACUUM RELATED FORCES - A plastic container having a base portion adapted for vacuum pressure absorption. The base portion including a contact ring that supports the container, an upstanding wall, and a central portion. The upstanding wall being adjacent to and generally circumscribing the contact ring. The central portion defined in at least part by a pushup and an inversion ring that generally circumscribes the pushup. The pushup and the inversion ring being moveable to accommodate vacuum related forces generated within the container.06-25-2009
20090202766FLEX RING BASE - Accordingly, the present disclosure provides a container and method of making a container. In one example, a preform is disposed into a mold cavity having a base forming assembly. The base forming assembly includes a base insert and a movable ring insert. The preform is blown against the mold cavity to form a body defining a base portion. The movable ring insert is advanced into the base portion to form a thinned flex point in the base portion while keeping the base insert fixed. The container is hot-filled with a commodity. The commodity is allowed to cool causing a vacuum in the container that results in the upward movement or inversion of a central inset portion defined at the thinned flex point.08-13-2009
20090218733LIQUID OR HYDRAULIC BLOW MOLDING - An apparatus and method for simultaneously forming and filling a plastic container is provided. A mold cavity defines an internal surface and is adapted to accept a preform. A pressure source includes an inlet and a piston-like device. The piston-like device is moveable in a first direction wherein liquid is drawn into the pressure source through the inlet and in a second direction wherein the liquid is urged toward the preform. A blow nozzle may be adapted to receive the liquid from the pressure source and transfer the liquid at high pressure into the preform thereby urging the preform to expand toward the internal surface of the mold cavity and creating a resultant container. The liquid remains within the container as an end product.09-03-2009
20100136158Liquid or Hydraulic Blow Molding - An apparatus and method for simultaneously forming and filling a plastic container is provided. A mold cavity defines an internal surface and is adapted to accept a preform. A pressure source includes an inlet and a piston-like device. The piston-like device is moveable in a first direction wherein liquid is drawn into the pressure source through the inlet and in a second direction wherein the liquid is urged toward the preform. A blow nozzle may be adapted to receive the liquid from the pressure source and transfer the liquid at high pressure into the preform thereby urging the preform to expand toward the internal surface of the mold cavity and create a resultant container. The liquid remains within the container as an end product.06-03-2010

20120093965BLOW NOZZLE TO CONTROL LIQUID FLOW WITH PRE-STRETCH ROD ASSEMBLY - An apparatus for forming a container comprising a housing and a rod apparatus disposed in the housing. The rod apparatus includes a rod for at least partially forming a container preform. The apparatus further includes a nozzle system disposed in the housing that is operably coupled with the rod apparatus. The nozzle system is positionable between a first position preventing pressurized fluid from being injected into the container preform and a second position permitting pressurized fluid to be injected into the container preform.04-19-2012
20120207872BLOW NOZZLE TO CONTROL LIQUID FLOW WITH PRE-STRETCH ROD ASSEMBLY AND METAL SEAT SEAL PIN - An apparatus for forming a container from a container preform. The apparatus includes a housing, a mold cavity, and a nozzle system disposed in the housing and operably connectable to the mold cavity. The nozzle system is positionable between a first position engaging the housing along an interface of contact preventing pressurized liquid from being injected into the container preform and a second position spaced apart from the housing permitting pressurized liquid to be injected into the container preform. The nozzle system further includes in some embodiments a seal portion having a first surface—the first surface engaging a second surface extending from the housing in the first position.08-16-2012
20120207873REVERSE STRETCH ROD FOR MACHINE HYGIENE AND PROCESSING - A mold device for forming a plastic container from a preform. The mold device comprises a mold defining a mold cavity and a central exterior rod system moveably disposed within the mold cavity. The central exterior rod system is positionable between an extended position engagable with the preform and a retracted position spaced apart from the preform. The central exterior rod system maintains a central orientation of the preform during formation.08-16-2012
