Abstract (en)
[origin: WO0228728A1] The invention relates to a closing device (1) for a container (B) that comprises a bung-type lower part (2) with a cylindrical pour spout (20). The cylindrical pour spout has a female thread in which a cylindrical piercing element (3) that is open to both sides and that is provided with a male thread is retained by a screw connection. A screw cap (4) can be placed on the lower part, said screw cap being provided with driver means (44, 45) that interact with driver means (34) in the piercing element (3). A fine-pitch thread is provided between the screw cap (4) and the lower part and a coarse-pitch thread between the lower part and the piercing element. The combined screw/translational motion of the piercing element and the selected threads produce a highly effective cutting motion.
