摘要

The closure device comprises: a retention ring (40) seated around the container and axially locked between a finishing cord (13) and a peripheral rib (14), which are externally incorporated to an upper region (11) of the tubular body (10) of the container; and a locking ring (50) which is seated and affixed around an end cord (23) of the lid (20) and incorporating an outer skirt (53) surrounding the end cord (23) and the finishing cord (13) and being elastically deformable, from a locked position against upward displacement at the locking ring (40), to a position unlocked from the latter. The device may further comprise a suspension handle (70) coupled to the retention ring (40), and a seal means (60) cooperating with both the retention ring (40) and the locking ring (50) to make evident a first opening of the container.
