When the bag is placed in the dispenser the pump inlet connecter enters the bag connector, perforates the bag and snaps in place to form a liquid type seal. The halves of the connector are shaped so that only the correct two halves can be connected e.g. the opening may be of non-circular shape : Independent claims are also included for (a) The connector (b) The method of connection.
