Abstract: Closures with a tamper evidence feature that is reshaped to connect it to the container neck are disclosed. Methods and systems for carrying out the methods, and to mold stacks for making the closures are also disclosed. The tamper evidence feature can be a band, a portion of a cylindrical skirt or a panel formed in the cylindrical skirt. The application of heat may deform the band inwardly to create a lip for engaging a flange on the container neck, or it may weld the tamper evidence feature to the flange

Abstract: An injection molding apparatus comprises a support base and a mold carrier removably mounted to the support base. The mold carrier includes a mounting plate with attachment features for engaging the support base. A mold with two mold plates is slidably mounted to the mounting 5 plate. A clamp is operable to move the plates between open and closed positions. In the closed position, the plates abut one another. In the open position, the plates are spaced apart for removing molded articles.

Abstract: A molding apparatus for molding a closure device for a container. The closure device may be tethered to the container, and may open and close via a hinged articulation. The closure device includes a cylindrical body comprising hinge-connecting areas with pockets formed in the interior wall and defining an inner surface of the hinge-connecting areas, and hinges extending downwardly from the hinge-connecting areas and positioned at or below a bottom edge of the cylindrical body. The molding apparatus comprises a cavity insert component and a core component that cooperate to form mold surfaces to mold the closure device such that hinges are located below the cap area of the closure device, and hinge-connecting areas formed by projections in the core mold component and recesses in the cavity mold component are located within the cap area are flanked by membranous areas.

Abstract: In one aspect, a method of coinjection molding a multilayer article using a coinjection nozzle having inner outlet, an outer outlet, and an intermediate outlet between the inner and outer outlets is provided. A stream of surface layer material is injected into a mold cavity from the intermediate outlet. With the injection ongoing, two streams of internal layer material are injected from the inner and outer outlets of the coinjection nozzle respectively. The two streams sandwich the stream of surface layer material and flow behind a melt front of the surface layer material. The sandwiched stream of surface layer material continues to supply the melt front with surface layer material at least until the melt front nears a distal end of the mold cavity. The resultant article is substantially or entirely encapsulated by a skin of the surface layer material and contains a high proportion of internal layer material.

Abstract: In an aspect, a mold stack may comprise two adjacent components, one at least partially defining a vent adjustable between a molding configuration and a cleaning configuration. A junction of the components may be adjustable between a molding configuration, wherein mating faces contact one another to define a parting line, and a cleaning configuration, wherein mating faces are separated to create a molding cavity extension therebetween and an auxiliary melt barrier prevents uncontrolled flashing from the extension.

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: In one aspect there is disclosed a method of improving shot repeatability in a multilayer reciprocating screw injection molding apparatus by preventing pressure communication or “cross-talk” between melt channels. In the first aspect an outlet nozzle valve is closed prior to closing a check valve within an injection unit of the multilayer reciprocating screw injection molding apparatus. In another aspect there is disclosed a method of improving shot repeatability in a reciprocating screw injection molding apparatus by recording a first position of a screw within the barrel of an injection unit of a reciprocating screw injection molding apparatus, the first position corresponding to a volume of melt within the barrel of the material injection unit. A second position of the screw is then calculated based on the first position, the second position corresponding to a transition position of the screw within the barrel of the injection unit of the reciprocating screw injection molding apparatus.
