A closure element of the press-twist type for closing a container comprises: a capsule having a side wall extending about an axis, and a transverse panel extending transversely to said axis, an annular seal for sealingly engaging with a mouth of the container. The annular seal is made of a PVC-free material and comprises: a side portion arranged in contact with the side wall of the capsule; a front portion extending from the side portion towards said axis; a deformability promoting element for increasing deformability of the front portion, the deformability promoting element comprising a recessed zone configured to be at least partially filled by the material forming the front portion when the front portion is pressed against an edge of the container delimiting the mouth.

A packaging container has an improved degree of freedom in the shapes of a container body and a cap, and prevents required turning force from being excessively large. The packaging container includes a container body having an upward-facing mouth, and a cap for closing the mouth. The container body has a plurality of axial drive ribs and a circumferential locking groove formed on an outer perimeter of the mouth. The cap has protruding rib portions on an inner surface side and locking claws to elastically lock into the locking groove, extended down from a top surface thereof.

Embodiments of the present invention relate to a mouth piece for a bottle with a twist-off crown cap closure, wherein the mouth piece comprises a mouth piece body with a dispensing opening at the end; a closure thread for interaction with a twist-off crown cap in order to close off the dispensing opening so that it is liquid-tight, which closure thread comprises a plurality of thread protrusions arranged over regions of the circumference of the mouth piece body at a predeterminable thread pitch, protruding from the exterior side of the mouth piece body; a discontinuity running circumferentially around the mouth piece body, arranged between the dispensing opening and the closure thread and formed as a result of a tool during manufacture of the mouth piece in a transition region between two orifice jaws on the one hand, and a guide disc on the other hand; wherein an exterior end of the discontinuity is offset inwards relative to an exterior surface of the mouth piece body situated between axially adjacent thread protrusions. Likewise, embodiments of the present invention relate to a corresponding bottle, to a tool for producing a mouth piece for a bottle with a twist-off crown cap closure, and to a method for producing a mouth piece for a bottle with a twist-off crown cap closure.

A closure including an upper wall (25) defining an opening (36) and a cylindrical snap on pipe (30) depending from the upper wall. The pipe includes threads (34) designed to mate with external threads on a neck of the bottle. The threads on the pipe and threads on the neck of the bottle pass over each other when the closure is snapped onto the bottle during manufacture. The pipe includes a resistance recess (42) and a guidance recess (70). The resistance recess and the guidance recess accommodate a forcing element (50) on a shoulder (80) of the bottle and permit unscrewing of the closure. The walls (44, 46) of the resistance recess are preferably symmetrical.

A tamper-resistant lid assembly for dispensing a premeasured amount of liquid from a beverage container and a method of providing a tamper-resistant lid assembly for use in dispensing a premeasured amount of liquid. The assembly includes a cup and a ring that are secured to one another using a snap-fit connection, as well as a lockable connection enabled by a selectively twistable rotation of the cup and the ring once the snap-fit connection is established.

A snap-on/twist off closure (22), a package comprising the closure, e.g., a bottle in combination with the closure is disclosed. The closure includes an upper wall defining an opening and a cylindrical snap on pipe (30) depending from the upper wall. The pipe includes threads designed to mate with external threads on a neck of the bottle. The threads on the pipe and threads on the neck of the bottle pass over each other when the closure is snapped onto the bottle during manufacture. The pipe includes a resistance recess (42) and a guidance recess (70). A bottom rim of the pipe, the resistance recess and the guidance recess are in contact with a forcing element (50) on a shoulder of the bottle and guide the closure into positions permitting unscrewing of the closure.
