Closure assembly for a container and container having a closure assembly

A closure assembly couplable to a container filled or fillable with a pourable product, the closure assembly comprising at least:

• a lid that is rotatable and has a first rim;
• a ring member having a second rim facing the first rim;
• a coupling element connected to the lid and to the ring member;
• a tamper-evidence ring positioned so that the ring member is axially between the lid and the tamper-evidence ring;
• at least one rupturable coupling bridge connecting the tamper-evidence ring and the ring member;
• a tubular cutting device movable from a rest position to an operative position in response to initial rotation of the lid when the closure assembly is coupled to the container to produce a hole in the container;
• the coupling element comprising at least:
• one respective intermediate portion;
• one respective first curved portion connected to the first rim and the intermediate portion;
• one respective second curved portion connected to the second rim and the intermediate portion;
• and
• the intermediate portion being inclined with respect to the first rim of the lid and/or the second rim of the ring member.

A closure assembly couplable to a container filled or fillable with a pourable product, the closure assembly comprising at least:

• a tubular collar surrounding a flow channel for the pourable product;
• a lid engaged with and rotatable relative to the collar, the lid having a top wall and a first rim;
• a ring member having a second rim facing the first rim;
• a coupling element connecting the lid and to the ring member;
• a tubular cutting device positioned inside the tubular collar and movable away from the top wall of the lid from a rest position to an operative position in response to initial rotation of the lid when the closure assembly is coupled to the container to produce a hole in the container;
• the coupling element comprising at least:
• one respective intermediate portion;
• one respective first curved portion connected to the first rim and the intermediate portion;
• one respective second curved portion connected to the second rim and the intermediate portion;
• and
• the intermediate portion being inclined with respect to the first rim of the lid and/or the second rim of the ring member;
• and
• each first curved portion comprising a first engagement surface and each second curved portion comprising a second engagement surface, each coupling element being deformable such that the first engagement surface abuts against the lid and the second engagement surface abuts against the ring member.
