Abstract Plastics Cap for Blow-Moulded Plastics Containers Such plastics caps comprise an outer rim (4) surrounding the container neck (3) and an inner ring (5) extending into the container neck (3), projecting beyond the cap bottom (6) beneath the container opening. as well as a sealing ring fitted in between cap outer rim (4) and cap inner rim (5). This is pressed against the opening margin (14) of the container neck (3) by a clamping ring (10) or tightening wire, wherein the clamping ring (10) or tightening wire engages over a flange (11) or flange sections formed below on the cap outer rim (4) and engages under a flange or rib (12) or flange sections projecting radially outwardly from the container wall at a distance below the container opening. There is formed an annular web (8) projecting axially from the bottom of the annular space (7) formed by the cap outer and inner rims (4, 5). This conducts the axial forces created with the cap (1) closed by stacking, dropping, etc. directly into the container neck (3). Sealing rings (13) are arranged on both sides of the annular web (8) and bear with pre- tension on the opening margin (14) of the container neck (3) with the cap (1) closed. (Figure 2)
