## Background
CROSS REFERENCE TO RELATED APPLICATION
This application claims the benefit of U.S. Provisional Application No. 61/972,845 (0010.0005.001), filed Mar. 31, 2014.


TECHNICAL FIELD
The field to which the disclosure generally relates includes containers and caps for holding fluids wherein the structure includes a sealing member acting at the junction of the closure and closure support or container mouth to oppose the passage of fluid therebetween.
BACKGROUND
Storage of carbonated liquids such as beer may include the use of a glass growler. Glass growlers temporarily hold the carbonation and temperature of a liquid but leak gas which may result in lost carbonation. Glass growlers are commonly rated for low internal pressures. Glass growlers typically utilize a metal cap to seal the carbonation and liquid within the growler, which, when opened, releases carbonation and exposes the liquid to air. Mini-keg growler variations are disclosed in U.S. Ser. No. 14/075,563, filed Nov. 8, 2013, and titled Mini-Keg Growler, the disclosure of which is hereby incorporated by reference.
