Abstract
A dispensing container has a spout formed of opposing walls of supple, imperforate material joined along their side edges with at least a portion thereof being formed over a curved surface. The aforementioned portion of the spout is thus set in a curled condition in the direction of discharge with the walls in face-to-face contact to effect a valving action. The spout can include a metering chamber to permit a desired quantity of fluid contents to be separated and milked through the curled portion to the discharge end of the spout. If desired, the entire dispensing container can be similarly formed over a curved surface so that the empty end of the container opposite the spout will also assume a curled conformation as the container's contents are discharged through the spout.
