Disclosed herein, amongst other things, is, a stripper assembly operable to eject a molded article from a mold that includes slides that are movable laterally relative to each, a first split mold insert inter-connected to a first slide and a second split mold insert inter-connected to a second slide. The system being operable such that when the first and second slides are in the closed position, the first and second split mold inserts form at least a portion of the molding cavity; the system being operable such that such during operation of the injection molding system, the first split mold insert is movable relative to the respective first slide and the second split mold insert being movable relative to the second slide.

A bottle for containing an item, generally a pharmaceutical product, wherein the bottle includes a body having a bottom wall and sidewalls, a neck extending from a top portion of the sidewalls and a thread defined on the neck. The neck defining a mouth of the bottle, an internal surface and an external surface. A neck thickness is defined between the internal surface and the external surface. The thread defines a thread thickness. The thread thickness is substantially the same as the neck thickness.

A method for forming a container assembly having a lid, a container and a cooperative closure mechanism, includes providing a lid form and flexible members biased toward the lid form, wherein the lid form and the flexible members are operable between a forming position defined by the lid form exerting a biasing force against the flexible members, and an extraction position defined by the biasing force being substantially removed from the flexible members, creating a lid form cavity defined by the lid form and the flexible members disposed in the forming position, injecting a lid material throughout the lid form cavity to form a lid, disposing the lid form and the flexible members in the extraction position, wherein the lid form is moved distal from the lid and the flexible members are biased away from the lid to separate the lid from the flexible members.

An in-mold shutter (140) for embedding in an injection mold (100, 200, 300) is described herein. The in-mold shutter (140, 240, 340, 440, 540) includes a shutter actuator (148, 548) that is configured to selectively engage a first mold shoe (130) of the injection mold (100, 200, 300) with a platen of a mold clamping assembly (996) to hold the first mold shoe (130) in an extended position (E), along a mold-stroke axis (X), during a step of molding a first molded article (102A) in the injection mold (100, 200, 300). Also described herein is a molded article transfer device (150, 250) for use with the injection mold (100, 200, 300). The molded article transfer device (150, 250) includes a shuttle (154) that is slidably arranged, in use, within the injection mold (100, 200, 300). The shuttle (154) defines a first aperture (156A), at least in part, that alternately accommodates: (i) a first mold stack (106A, 206A, 306A) arranged therein; and (ii) a first molded article (102A) received therein with opening of the first mold stack (106A, 206A, 306A).

A mold apparatus for molding a rotating member includes: a column mold portion including a first column molding hole extending in a first direction and configured to mold a column portion therein and a first blade molding groove formed as an intaglio on an inner circumferential surface of the first column molding hole to have a shape corresponding to a blade and configured to mold the blade therein, and an extraction guide configured to push a first end of the column portion in the first direction to thereby extract the column portion from the first column molding hole, at least a portion of the extraction guide being positioned inside the first column molding hole. The extraction guide is configured to press the column portion to thereby extract the column portion from the first column molding hole while the column portion rotates in an inclined direction of the blade.

A collapsible core of an injection mold includes relatively movable components arrayed about an imaginary centerline. When in an operational position for molding a new product, the movable components each define a separate segment of the exterior of the core, such as side by side segments of interior features such as a continuous set of threads to be formed in a product being molded. To move between operational and retracted positions, some core components are pivotally connected to a nest of the core, and others are translatably connected to the nest. When a newly molded product is ejected from the mold, ejection movement causes the pivotally connected core components to pivot to disengage the newly formed interior features, and causes the translatably connected components to translate to disengage the newly formed interior features.

A method for producing a package closure having a neck, a cap and an axis (A) includes a) by means of movable jaws and a tool core forming the neck with an outer thread and the cap with an inner thread, wherein an interior of the neck is formed by an outer first tool core part, and wherein an interior of the cap is formed by an inner second tool core part and a third tool core part, the thread of the cap being formed by the third tool core part, b) removing the jaws from the formed package closure, c) axially displacing the second tool core part in relation to the first tool core part and thereby separating the cap and the neck, d) axially displacing the third tool core part in relation to the second tool core part and thereby disengaging the cap from the third tool core part while keeping the second tool core part engaged with the cap, e) displacing the neck axially in relation to the cap and bringing the thread of the cap into engagement with the thread of the neck through an inherent flexibility of the package closure to form a package closure having a cap mounted on the neck, and f) displacing the package closure in relation to the second tool core part to disengage the package closure from the tool core.
