Abstract: A molded article suitable for subsequent blow-molding into a final-shaped container. The article includes a neck portion; a gate portion; and a body portion extending between the neck portion and the gate portion, at least a majority of the body portion having an overall shape which is symmetric about a body axis extending longitudinally through a center of the body portion. The body portion includes an inner exterior layer and an outer exterior layer of a first polymeric material; and a core layer of a second polymeric material disposed between the inner exterior layer and the outer exterior layer. A radial thickness or a material of the core layer is selectively varied to govern non-uniform blow molding of the molded article into the final-shaped container.

Abstract: An injection mold (100) including a core plate assembly (200), a cavity plate assembly (400) and a stripper plate assembly (300) arranged between the core and cavity plate assemblies (200, 400). The mold (100) includes a plurality of mold stacks (MS) with a molding configuration, in which the mold stacks (MS) are closed to define molding cavities. A gap (G) is provided between the core plate (210) and the stripper plate (310) when the mold (100) is in the molding configuration, such that a clamping load (CL) applied to urge the core plate (210) toward the cavity plate (410) is directed substantially entirely through the mold stacks (MS).

Abstract: A closure may have a top wall and a side wall depending from the top wall. A plug seal device may depend from said top wall within the side wall. The plug seal device may have an upper section, a lower section, and a sealing section proximate the boundary between the upper section and the lower section. The sealing section is operable such that when the plug seal device is inserted in an opening to an inner cavity in a container, the sealing section engages with an inner container surface to provide a seal between an inner cavity of the container and the external environment.

Abstract: In one aspect, there is provided an injection molding system configured to operate in a plurality of cycles. The system comprises, amongst other things, a controller that is configured for performing a comparison of a variable pressure setpoint with a target pressure value. The controller is configured to, when the target pressure value is less than the variable pressure setpoint by at least a predetermined lower bound, (i) decrease the variable pressure setpoint to a reduced variable pressure setpoint and (ii) not further decrease the variable pressure setpoint from the reduced variable pressure setpoint until the pump assembly operates for a plurality of stabilizing cycles at the reduced variable pressure setpoint.

Abstract: A closure for sealingly closing a container neck having a tubular body with a top wall, an annular side wall, an intermediate wall joining the side wall to the top wall and an annular tamper evidence band frangibly connected to an open end described by the side wall. The band includes retaining cams protruding from its inner surface. Each cam has a lead-in ramp for engaging, in use, the flange of a container neck as the neck is introduced into the open end of the body and a stop for engaging the flange to separate the band from the body when the closure is subsequently removed from the neck. Each lead-in ramp has a central recess therein.

Abstract: A closure (1) with a shell (2) for securement to a container neck (11) and a lid (3) pivotally connected to the shell (2) by a pair of hinge elements (6). A hinge line (50) in the side wall (5) delineates a deformable latch (8) having an external grip tab (80) and an internal 5 engaging tab (82) between the grip tab (80) and a top wall (4) of the lid (3). The grip tab (80) extends radially from a side wall (5) of the lid (3) and the engaging tab (82) engages a lip (13) surrounding the mouth of the container neck (11). The deformable latch (8) is configured to deform along the hinge line (50) when an opening force is applied to the grip tab (80), thereby to disengage the engaging tab (82) from the lip (13) of the container neck 10 (11).

Abstract: An injection molding system is disclosed herein that may include a manifold that may have a manifold melt channel for receiving melted resin, a nozzle having a nozzle melt channel for receiving the melted resin from the manifold melt channel and delivering the melted resin to a mold cavity via a mold gate. In other examples, a valve pin may extend through at least a portion of the nozzle melt channel such that a forward end of the valve pin may be seatable within the mold gate. In certain examples, the injection molding system may include one or more drop plate, each of which defines walls of a cylinder within which a piston reciprocates, and each which may contain cooling circuits and pressurized circuits for opening and closing the piston. With regard to injection molding system containing multiple drop plates, each drop plate is independent of the other drop plates, and each drop plate is dedicated to a single nozzle assembly. In other examples, the drop plates may house a valve pin coupling system configured to permit movement of a valve pin in a lateral direction independent from a lateral position of the piston.
