Locking cap for pouring nozzle of container

摘要

The cap comprises a seal (14) which is formed with the lid in one-piece, and is shaped as bead. The seal projects into a groove (24) of the pouring nozzle (21) and is sealingly supported in it. The seal is arranged at a distance to the cap casing (12) by an annular free-space (15). The seal is V- or U-shaped in cross-section, and its width, transverse to the peripheral direction on the connection position of the lid is larger than the groove interior. The seal width is smaller at its free end than the groove interior width.
