Abstract
A syphon package (12) incorporates a deformable, resilient plastic sealing member (42) which, in its normal position, blocks passageway (50) for dispensing seltzer water (32) stored under pressure in the package (12). Tube (30), valve sealing member (42) and insert (44) are assembled by bonding insert (44) to flange (40) with sealing member (42) in place. The resulting assembly is then bonded to interior wall (22) of necked opening (16). A syphon head (24) has a one-piece actuator (60) bonded to body (28), with actuating rod (62) supported on resilient diaphragm (64) for downward movement by lever (74) to deform sealing member (42) out of sealing engagement with passageway (50).
