Abstract

Abstract The dispensing closure is intended for a liquid container (4) for highly pure liquid chemicals. The dispensing closure has a closure flange (1) which is produced integrally as a plastic injection moulding made of fluorinated thermoplastic with a downwardly projecting immersion tube (6), an associated upwardly projecting connection nozzle (7) and a further connection nozzle (13). A collar plate (16), lying on the closure flange (1), presses the closure flange (1) against the container flange (2). The connection nozzle (7) of the immersion tube (6) and the further connection nozzle (13) are closed by screw-caps (12, 15) during transportation and storage. <IMAGE>
