Abstract: A method of producing a package closure (10) of plastic material by means of a mould comprising movable jaws (35, 36), a counterpart (37), an outer first tool core part (38), an inner second tool core part (39) and an ejector (40), wherein the outer first tool core part, the second tool core part and the ejector are axially displaceable relative each other, comprising the steps of axially displacing the outer first tool core part and the second tool core part in relation to each other in a first direction, thereby disengaging the cap from the outer first tool core part while keeping the inner second tool core part engaged with the cap, and then axially displacing the inner second tool core part and the outer first tool core part and/or the ejector (32) in relation to each other in the first direction or in an opposite second direction while folding a foldable portion (21) of the package closure inward through an inherent flexibility of the package closure (10), Disclosed is also a device for producing the pac

Abstract: A package closure (10) comprising a neck (18) provided with an opening, and a cap (19) for closing the opening, wherein the neck (18) comprises a connecting portion (20) for connection to a package (32), and a sealing portion (21) projecting radially inwards from the connecting portion (20) to interact with the cap (19) to form a seal between them. Before opening thereof the cap (19) is connected to the sealing portion (21) through a notch (23), wherein the cap (19) is removable from at least a part of the sealing portion (21) by tearing along the notch (23). The cap (19) is provided with a sealing part (24) projecting from an interior side of the cap (19) to interact with the sealing portion (21) of the neck (18), so that the package closure (10) is resealable. The invention also relates to a device and a method for producing a package closure.

Abstract: 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 th

Abstract: Device for a package closure comprising a cap (1) which is mounted on a package neck (2) alternative on a separately neck and where the cap in its final mounting position gives a sealing function implying that a sealing lip (10) of the neck will be pressed against an outer wall (32) of the cap, alternative that there is a further sealing lip 51 of the neck which presses against an opposite cylindrical section (33) of the cap (1) and that the complete package in this sealing position has a secured tightness and that the construction is designed in a way that a closure is obtained which gives conditions for a sterile environment in the package.

Abstract: A device designed to be mounted in a complete container, the device comprising a container neck (3), in which a valve membrane (2) is mounted and fixed, the membrane having an opening (8) in its centre, which interacts with a central pin (9), which is a part of the neck (3), and the membrane and its opening sealing the container, since the membrane with a certain surface pressure till be pressed against the central pin (9), and that the membrane, directly subsequent to an emptying or a partial emptying continuously closes the container anew, this being done without any air flowing backwards and into the partially emptied container.
