PACKAGE CLOSURE AND A DEVICE AND A METHOD FOR PRODUCING A PACKAGE CLOSURE AND USE OF SUCH A DEVICE

摘要

A method for producing a package closure (10) having a neck (18) and a cap (19), comprising the steps of by means of movable jaws (11, 12) and an outer tool core (16) forming the neck (18) and the cap (19) in one single integrated piece, wherein the neck (18) is connected to the cap (19) through a notch (23), by means of an inner tool core (17) forming a flexible projection (28) on an inner side of the cap (19) for interaction with the inner tool core (17), displacing the outer tool core (16) in relation to the package closure (10) and the inner tool core (17) to at least partially disengage the package closure (10) from the outer tool core (16), by means of the inner tool core (17) retaining the cap (19) by the projection (28) formed on the interior side of the cap (19) and simultaneously, by means of an ejector (15), displacing the neck (18) in relation to the cap (19) and breaking the notch (23) to form a package closure having a cap (19) mounted on the neck (18), by means of the ejector (15) displacing the package closure (10) in relation to the inner tool core (17), so that the projection (28) by its flexibility is disengaged from the inner tool core (17). The invention is also related to a package closure and a device for production thereof and use of such a device.

主权项

1. A method for producing a package closure having a neck and a cap, comprising the steps of
a) by means of movable jaws and an outer tool core forming the neck and the cap in one single integrated piece, wherein the neck is connected to the cap through a notch, and forming a thread on the cap and a thread on the neck, b) by means of an inner tool core forming a flexible projection on an inner side of the cap for interaction with the inner tool core, c) removing the jaws from the formed package closure, d) displacing the outer tool core in relation to the package closure and the inner tool core to at least partially disengage the package closure from the outer tool core, e) by means of the inner tool core retaining the cap by the projection formed on the interior side of the cap and simultaneously, by means of an ejector, displacing the neck axially in relation to the cap and thereby breaking the notch and bringing the thread of the cap into engagement with the thread of the neck through an inherent flexibility of the threads to form a package closure having a cap mounted on the neck, f) by means of the ejector displacing the package closure in relation to the inner tool core, so that the projection by its flexibility is disengaged from the inner tool core.
