A flexible container for liquid storage including a collapsible bag element enclosed within an outer bag and integrally formed with a neck defining an opening for liquid flow therethrough and a valve for controllably determining the flow rate of stored liquid through the neck including an outer cap, protrusions being formed both on the lower edge of the outer cap and on the upper edge of the neck and arranged such that rotation of the outer cap relative to the neck from a fully closed position to a flow position causes engagement of the protrusions and a user-sensible resistance to rotation.

A flexible container for liquid storage, said container comprising: a collapsible bag element enclosed within an outer bag and integrally formed with a substantially circular neck defining an opening for liquid flow therethrough, the interior of said neck having a recessed annular lip formed at the top end thereof; and valve means for controlling the flow rate of stored liquid through said neck, said valve means comprising a substantially cylindrical outer cap and an inner valve plug retained in a centrally located opening thereof, said inner valve plug being shaped to form at least one surface flow channel adjacent thereto said outer cap and said neck having respective matching interior and exterior threads for providing shut-off and flow positions upon rotation of said outer cap, wherein said inner valve plug is respectively seated on and spaced apart from said recessed annular lip for blocking and enabling liquid flow through said at least one adjacent surface flow channel for discharge through the central opening in said outer cap, said flexible container being further characterized in that protrusions are formed both on the lower edge of said outer cap and on the upper edge of said neck and arranged such that rotation of said outer cap relative to said neck from a fully closed position to a flow position causes engagement of said protrusions and a user-sensible resistance to rotation.
