ABSTRACT:
A valve arrangement for dispensing liquid from a flexible container (124) containing a dispenser body (106) connected to a flexible container (124) for containing a liquid and a first biasing means (168) adapted to bias a first closing member (110) to close off a first passage (107) in the container dispenser body (106); and a valve body (118) with a second biasing means (120) adapted to bias a second closing member (116, 118) to close off a second passage (119) defined in the valve body (118); and a dispensing member (122) operatively connected to the valve body (118); and operating means (114, 198, 136) which moves the two bodies (118, 106) into an operative position, against the two biasing means (168, 120) to open the two passages (107, 119) allowing liquid to flow from the flexible container (124) along the first passage (107) and out of the second passage (119).
