Closure device for metallic containers

摘要

The closure device includes: a retention ring seated around the container and axially locked between a finishing cord and a peripheral rib, which are externally incorporated to an upper region of the tubular body of the container; and a locking ring which is seated and affixed around an end cord of the lid and incorporating an outer skirt surrounding the end cord and the finishing cord and being elastically deformable, from a locked position against upward displacement at the locking ring, to a position unlocked from the latter. The device may further include a suspension handle coupled to the retention ring, and a seal means cooperating with both the retention ring and the locking ring to make evident a first opening of the container.
