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).

A syphon assembly for use with a container having a necked opening and holding a liquid under pressure, which comprises a tube dimensioned to extend from the necked opening into the liquid in the container, a valve positioned proximate to the necked opening end of the said tube and having a passageway for the liquid to flow from said container through the necked opening, said valve having a frustoconical shaped resilient sealing member having an open base engaging said tube and a top normally biased by the resilient sealing member into sealing engagement with the passageway of said valve, an actuating member positioned in a syphon head to apply force to deform said resilient sealing member to move its top out of the sealing engagement with the passageway of said valve, said resilient sealing member having a plurality of apertures spaced around the top to allow the liquid to pass from said tube to the passageway of said valve when said resilient sealing member is deformed, means extending from said syphon head for applying force to said actuating member to deform said resilient sealing member, a body having a means for attaching said syphon head to the necked opening, said valve comprising an insert member positioned over said sealing member and bonded to the necked opening end of said tube around said sealing member, said insert having a side configured for bonding in a sealing fit to an interior surface of the necked opening of the container, said insert having a centrally disposed opening comprising the passageway of said valve, through which said actuating member contacts said sealing member, said actuating member comprising, in integral form, a rod extending into said centrally disposed opening and a resilient diaphragm extending substantially normal to said rod, said resilient diaphragm being fixedly attached around its periphery to said body, and said rod extending below said diaphragm to contact said sealing member.
