Abstract: The present invention provides a closure cap for a container comprising a lid and a shell, and a hinge region for pivotally connecting the lid to the shell and for locking the lid in an open position thereof. The lid comprises a top panel having a tongue adjacent the hinge region and a cylindrical wall suspended from a bottom face of the top panel and connected to the shell via a plurality of bridges which break upon a first opening of the lid. The hinge region comprises a pair of elongate hinge elements spaced apart from each other, and a ratchet-like member disposed therebetween.

Abstract: An apparatus and method for actuating a valve stem between an open position and a closed position and for taking one or more valve gated nozzle out of service is disclosed. The hot runner includes a valve gated nozzle having a valve stem, the valve stem coupled to a piston that is held against an actuation plate via pressurized air. When a valve stem becomes stuck in a gate of the hot runner, the actuation plate can continue to move while the piston remains stationary. The valve stem may also be protected from an over force situation such as if the valve stem encounters an obstruction as the actuation plate is moving toward the closed position.

Abstract: In one embodiment, a gate insert includes an injection gate body having front and rear opposite sides and an aperture extending through the injection gate body between an injection gate outlet on the front side and an opening on the rear side. The injection gate body is connectable to and disconnectable from a gate pad in a cavity plate from a front side of the gate pad and from a front side of the cavity plate. In another embodiment, a cavity flange includes a molding body defining at least a portion of a molding cavity shaped to mold a shell of a closure for a container. The molding body is connectable to and disconnectable from a gate insert in a cavity plate from a front side of the gate insert and from a front side of the cavity plate. Other apparatuses are disclosed.

Abstract: Disclosed herein, amongst other things, is a method for converting a design of an original preform that is blow moldable to form a container into a converted preform having less molding material that is blow moldable to form the same container. The method includes retaining a neck finish and body of the original preform on the converted preform. The method further includes replacing the original base of the original preform with a converted base having an outer base surface that joins with an outer body surface of the body at an base split-line of the original base and that fits offset within an outer body surface of the original base, whereby the converted preform has a reduced total length, disregarding any gate vestige that may be formed thereon, relative to a total length of the original preform.

Abstract: An injection molding machine includes a nozzle with a nozzle body having inner and outer flow channels, and at least one intermediate flow channel in between. A valve stem is slideable in the inner flow channel and moveable between open and closed positions. In a first closed position, the valve stem blocks an outlet of the inner flow channel but not outlets of the outer or at least one intermediate flow channels. In the open position, melt exiting the at least one intermediate flow channel simultaneously intersect melt exiting the outer and inner flow channels. The flow channels may be arranged concentrically. The outlets of the flow channel may be separated by a knife edge. The outlets of the flow channels may be adjacent to one another. The inner and outer flow channels may be substantially perpendicular to one another, but not to the at least one intermediate flow channel.

Abstract: A preform suitable for subsequent blow-molding into a final-shaped container comprises: a neck portion; a base portion; and a body portion extending between the neck portion and the base portion; the body portion being defined between an inner surface having a circular transverse cross-sectional shape and an outer surface also having a circular transverse cross-sectional shape, the inner and outer surfaces being non-concentric, such that a wall thickness of the body portion varies circumferentially around the preform. A preform handling apparatus for retrieving a preform from a mold comprises a take-off device having a preform carrier and a take-off device alignment mechanism for maintaining the preform carrier in alignment with a contact surface of a body portion of the preform regardless of any offset between a longitudinal axis of a cylindrical outer surface of the body portion and a longitudinal axis of a cylindrical inner surface of the body portion.
