The closure (1) includes a filling nozzle (5) having a tubular stub (7) and a flange (10). The flange (10) has a tubular cylindrical portion (11) and a plate-shaped portion (12). The plate-shaped (12) portion of the flange (10) is attached to the container (3). The filling nozzle (5) may be caused to sealingly engage the flange (10) by use of a snap connection (14), whereby the closure is either completely open or closed. The snap connection (14) either retains the filling nozzle (5) in firm and tight engagement with the flange (10), or releases the filling nozzle (5) in relation to the flange (10).</p> |
