Screw cap closure for a plastics/cardboard container, for liquid foods, has a cutting unit within the base body with an interrupted thread for the screw cap to be assembled from above without screwing or pressure

摘要

The pouring cap for a container of a plastics/cardboard compound material to hold liquid foodstuffs, which can be closed after use, has a base body (1) with a flange (4) around it together with a stable inner thread (5) and an outer thread (6). It has a carton opening unit (2) with at least one cutter and a screw cap (3) to act on the cutting unit outer thread (8) to open the carton initially. The cutting unit outer thread is reduced or interrupted at least in one zone (8F) at the lower end, matching an interrupted section of the inner thread in the base body for initial assembly when the cap is pressed over the base without screwing or excessive pressure.
