A safety vent seal assures a release path for the residual volatile beverage that can be expected to be found within a disposable container. The container is sealed by an inner valve is urged toward a sealing relationship with an outer valve member by a semi-compressed spring and the second valve is urged toward a sealing relationship with the valve body by a second semi-compressed spring. The safety vent seal may be located either between the inner valve and the outer valve or between the outer valve and the valve body. In the former case, the safety vent seal is generally cross-shaped while, in the latter case, the seal is generally “C-shaped”. In both configurations, the seal expands as a consequence of the tapping of the valve and inserts itself into an otherwise-sealed relationship. aperture notch expand, preventing the valve from resealing when the tap is removed.

In apparatus for dispensing a beverage of the type that includes an inner valve that is urged toward a sealing relationship with an outer valve by means of an inner spring, the improvement comprising: (a) a resilient safety vent seal located between said inner and said outer valve; (b) said seal including means for permitting fluid flow between said inner and outer valves; and (c) said safety vent seal is actuated from a first predetermined compressed configuration to a second predetermined uncompressed configuration by the opening of said valve whereby said second configuration prevents an airtight sealing relationship between said inner valve and said outer valve.
