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 package closure (10) and various embodiments of package closures.

A packaging assembly includes a bottle, which may be used upside-down such that a neck is turned towards the ground, and a closure without any added seal gasket for closing the neck. This closure includes a cap for obturating the neck, and a skirt for attachment to the neck. The cap includes an inner sealing lip, delimiting on its outer face, a convex tight bearing surface for bearing tightly against the inner face of the neck, and a substantially flat ramp surface, which connects the tight bearing surface to a lower axial end of the lip, and which, while the lip is deformed with the remainder of the closure when an inner clip of the skirt interferes with an outer bead of the neck during placement of the closure on the neck, may interfere with a free end of the neck to guide engagement of the lip inside the neck.

Disclosed is a cap (4) for a container (1) and a container (1) thereof. The cap (4) configured to be mounted on the container body (2) comprises a cap body (15) formed with a liquid path (24) and a gas path (25) therein, wherein the liquid path (24) is configured for liquid to go through from the container (1) and the gas path (25) is configured for gas to go through to balance pressures inside and outside the container (1), and a top plate (16); characterized in that the top plate (16) is detachably connected with the cap body (15) to seal the liquid path (24) and the gas path (25).

A closure assembly comprises an article (10, 10, 10, 410) and a cap (40, 40, 40, 40, 440) provided with an integrated tamper-evident ring member (50, 50, 50, 450). The article further comprises a circumferential flange structure (20) with an annular flange portion and a peripheral protective rim portion (25) so that the top face (21a) of the flange portion and the protective rim define an annular recess (30) around the neck (14). The tamper-evident ring member is integrally formed to the lower edge of the skirt (42) of the cap via one or more breakable bridges (70). The ring member comprises an annular ring member flange portion (51) that has a top face (51a) and a bottom face (51b). Multiple hook members (53) are integrally formed to the bottom of the ring member flange portion, and the annular flange portion on the neck is provided with multiple hook member passages (1S). Each hook member passage is adapted to receive a hook member when the cap with the integrated tamper-evident ring member is axially mounted on the neck by means of an axial securing motion, wherein the hook portion (55) of each hook member snaps underneath the bottom face (21b) of the annular flange portion on the neck of the article. The periphery of the annular flange portion of the ring member is shaped to fit within the protective rim portion and the rim portion obstructs lateral access from outside to the interface between flange portions.
