Mini-keg growler

A mini-keg growler comprising:

• a first cap comprising an upper circular surface opposite a lower surface and spaced apart by a cylindrical side surface having a plurality of parallel striations disposed thereon, and a cap nipple extending from the lower surface of the first cap comprising a groove adjacent to the lower surface and outer threading on an outer surface of the cap nipple, and an o-ring disposed within the groove;
• a first container comprising a generally cylindrical body portion defining a first cavity and that comprises a closed end portion comprising a bottom surface defining a circular outer lip affixed to the generally cylindrical body portion of the closed end portion, an indent located generally at the center of the closed end portion, and a generally circular rib disposed therebetween, the first container further comprising a conical portion extending opposite the closed end portion and converging toward and being affixed to a neck defining a passage in fluid communication with the first cavity and constructed and arranged to receive the first cap and sealingly close the cavity, wherein the neck further comprises an inner threading within the passage constructed and arranged to thread and mechanically engage with the outer threading of the cap and a chamfered flange constructed and arranged to receive and engage the o-ring to sealingly close the cavity when the first cap is threaded with the neck so that the chamfered flange is fully and directly engaged with the o-ring disposed in the groove, wherein the high pressure vessel is constructed and arranged to withstand internal pressure to about 50 PSI, wherein the chamfered flange extends outwardly from an outer surface of the neck at a predetermined angle;
• and
• a collar extending from the conical portion of the container and ending at a first rolled lip and further comprising a second rolled lip defining at least one through hole in the collar.

A mini-keg growler comprising:

• a first cap comprising an upper circular surface opposite a lower surface and spaced apart by a cylindrical side surface having a plurality of parallel striations disposed thereon, and a cap nipple extending from the lower surface of the first cap comprising a recessed groove adjacent to the lower surface and outer threading on an outer surface of the cap nipple, and an o-ring disposed within the groove;
• and
• a first container comprising a generally cylindrical body portion defining a first cavity of about one gallon or less in volume and that includes a closed end portion comprising a bottom surface defining a circular outer lip affixed of the generally cylindrical body portion to the closed end portion, a truncated cone shaped indent located generally at the center of the closed end portion wherein the truncated cone shaped indent comprises a plateau located generally at the center of the truncated cone shaped and indent and the closed end portion, and a generally circular rib disposed therebetween, the first container further comprising a conical portion extending opposite the closed end portion and converging toward and being affixed to a neck defining a passage in fluid communication with the first cavity and a chamfered flange constructed and arranged to receive and engage an o-ring to sealingly close the cavity when the first cap is threaded with the neck so that the chamfered flange is fully and directly engaged with the o-ring disposed in the groove when the cap is closed.

• and
• a collar extending from the conical portion of the container and ending at a first rolled lip and further comprising a second rolled lip defining at least one through hole in the collar.

• and
• wherein the neck further comprises:
• an inner threading within the passage constructed and arranged to thread and mechanically engage with the outer threading of the cap;
• and a chamfered flange constructed and arranged to receive and engage the o-ring to sealingly close the cavity when the first cap is threaded with the neck so that the chamfered flange is fully and directly engaged with the o-ring disposed in the groove, and wherein the chamfered flange extends outwardly from an outer surface of the neck at a predetermined angle ranging from about 30 to about 60 degrees from parallel with the neck.
