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.

Closures with tamper evidence

A plastic molding system comprises: dispensing, pre-shaping and shaping cells and a transport subsystem. The dispensing cell has a station for dispensing a dose of plastic feedstock. The pre-shaping and shaping cells each comprise a plurality of stations for shaping the workpiece into a preform shape and into a final shape, respectively. The transport subsystem advances a workpiece along a selected one of a plurality of process paths to form a molded article. Each of the plurality of process paths is defined by a combination of stations of the dispensing cell, the pre-shaping cell and the shaping cell.

Molding apparatus and methods

Method of securing a closure on a container

A closure device for a container having a neck including an annular flange, the closure device comprising: a cap body; a tamper evident (TE) band positioned below the annular flange when assembled in the container; a first hinge and a second hinge defined on the cap body; a leash connected to the TE band, the first hinge and the second hinge; the leash allowing for the cap body to be separated from the TE band during opening, but to remain connected thereto via the leash; a tongue protruding from the cap body between the first and second hinges; when the cap body is actuated from a closed configuration relative to the neck to a fully open position: the leash is configured to retain the cap body to the TE band; an interaction of the tongue and the neck is configured to retain the cap body in the fully open position.

Closure device for a container

A misalignment sensing system for a molding structure and a method for using same. The molding structure includes a first component and a second component, at least one of the components being selectively repositionable between a closed configuration of the mold structure and an open configuration of the mold structure. The misalignment sensing system includes an alignment member including a male portion coupled to and extending from the first component of the molding structure, and a female portion defined in the second component of the molding structure, the female portion being configured to receive the male portion when the molding structure is in a closed configuration; and at least one sensor connected to one of the male and female portions and being configured to detect a deformation of any one of the male portion and the female portion, the deformation being induced by a misalignment of the molding structure.

Injection molding apparatus and method of detecting misalignment in the injection molding apparatus

The invention pertains to an injection molding machine comprising, an injection nozzle () having a melt channel (), an injection opening (), and a filter () for filtering the molten resin within the injection nozzle (). According to the invention, the melt filter () cooperates with the 5 melt channel () or a means () provided within the melt channel () in such a way, that during an injection phase of the injection molding machine, the molten resin is caused to pass through the filter (), and during a decompression phase of the injection molding machine the molten resin is caused to bypass the filter ().

Injection molding machine

Wings are provided on mold components and linear ways are provided below these wings. A pad rides on each linear way below each wing. A force generator, such as a spring, is disposed between each wing and underlying pad. In this way the weight of the mold components is borne, at least in part, by the linear ways so that the weight on components that might otherwise sag is lessened.

Weight compensated molding machine

A screw-moving assembly () for a screw assembly (), the screw-moving assembly () comprising: a screw-moving actuator (); and a bias-adjustment mechanism (); wherein the screw-moving actuator () and the bias-adjustment mechanism () are configured to connect to the screw assembly (); the screw-moving actuator () is configured to transmit, in use, a screw-translation force () to a longitudinal central axis () of the screw assembly (); and the bias-adjustment mechanism () is configured to transmit, in use, a biasing force () to the longitudinal central axis () of the screw assembly ().

Screw-moving assembly including screw-moving actuator and bias-adjustment mechanism

An in-mold shutter () for embedding in an injection mold () is described herein. The in-mold shutter () includes a shutter actuator () that is configured to selectively engage a first mold shoe () of the injection mold () with a platen of a mold clamping assembly () to hold the first mold shoe () in an extended position (E), along a mold-stroke axis (X), during a step of molding a first molded article (A) in the injection mold (). Also described herein is a molded article transfer device () for use with the injection mold (). The molded article transfer device () includes a shuttle () that is slidably arranged, in use, within the injection mold (). The shuttle () defines a first aperture (A), at least in part, that alternately accommodates: (i) a first mold stack (A,A,A) arranged therein; and (ii) a first molded article (A) received therein with opening of the first mold stack (A,A,A).

A controller () is described herein that includes instructions () that are embodied in a controller-usable memory () of the controller (), the instructions () for directing the controller () to execute a process () of injection molding a first molded article (A) using an injection mold (). The process includes, amongst other things, a step of arranging () a first stack portion () to eject the first molded article (A) therefrom with holding a position of a stripper sleeve () of the first stack portion (), along the mold-stroke axis (X), while retracting a mold core () of the first stack portion () along the mold-stroke axis (X), wherein the retraction of the mold core () causes a retraction thereof from the first molded article () in cooperation with the stripper sleeve () contacting the first molded article ().
