BARREL WITH INNER BAG Russian patent published in 2008 - IPC B67D1/04 

FIELD: mechanics.

SUBSTANCE: lock ring to fix the bag neck in the neck of the barrel for alcoholic drinks is tightly fitted on the bag neck outside wall. This ring has an outer wall part greater in size compared to the barrel neck. The ring has, also, a groove made on its outer wall part to tightly receive the barrel flange provided just around the barrel neck. The lock outer wall part has an elastic end face part adjoining the groove and enveloping so that the lock ring can enter the barrel neck, while the barrel flange can be fitted into the lock ring groove as required. A group of through holes is made all along the lock ring circumference. The barrel incorporates a catch with a number of locking rods penetrating axially between the bag neck and the lock ring groove. The said rods do not allow the elastic part of the lock ring to bend out after the said ring is fitted in the barrel neck.

EFFECT: efficient seal between the bag and the barrel.
