Plastics twist off closure cap for partly threaded container - has radially inner and concentric radially outer side, with sealing lip and tongues

摘要

The palstics closure cap (1) for a partially-threaded container, a twist-off cap, has a radially inner side (3) and a concentric radially outer side (4). A pressure-transfer piece (13) is positioned near the threaded-ridges (7) on the cap-side. The cap (1) is box-shaped with the two sides (3,4) joined by radial arms (6). The closure cap (1) incorporates a sealing-lip (8) radially inside the inner side-wall (3). The bottom of the cap (1) has a ring (15) the bottom edge of which has one or more radially inward-turned holder-tongues (9) on the outside of which is an inward-running round aprt (10). ADVANTAGE - The twist-off closure cap is recyclable and prevents the cap from being turned too far.
