An improved closure for sacks-wineskin characterized essentially by the fact of being constituted by a bag of adequate strength endowed with an inner covering formed by a layer of impermeable plastic material whose sack is attached by its mouth to a rigid cap included therein. Thanks to a surrounding pressure clamp, this bushing comprises an external thread for receiving a rigid sleeve carrying the set of closing levers and said bushing having another internal thread for coupling another threaded sleeve integral with a flexible tubular neck that constitutes the neck of the actual discharge of the sack-bag.
