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.

Disclosed herein, amongst other things, are various conversion structures for use in a molding system (). A non-limiting embodiment of the conversion structure includes a standard mold receiver () and a mold conversion module (A,B,C,A,B,C,D,E,F,A,B,C,A,B,C). The standard mold receiver () and the mold conversion module (A,B,C,A,B,C,D,E,F,A,B,C,A,B,C) are configured to cooperate, wherein the mold conversion module (A,B,C,A,B,C,D,E,F,A,B,C,A,B,C) is receivable in the standard mold receiver () for converting a molding configuration of a mold ().

Conversion structure for a molding system

The present invention provides an improved extruder assembly, that includes a wiper for wiping a screw portion in a low pressure extruder stage, whereby the wiping of the screw portion improves melt conveyance through the low pressure extruder stage. The present invention has particular utility when used in a low pressure venting and entrainment extruder stage of a single screw compounding extruder. The present invention also provides an extrusion/injection unit for use in-line compounding molding system that incorporates the improved extruder assembly.
