Method and a device for producing a package closure

Abstract

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.
