ABSTRACT:
A reversible closure-spout assembly which includes a flexible pour spout and a sealing member consisting of first and second spaced disks sealed to each other at their peripheries and defining a chamber therebetween, a series of slots formed through the first disk and communicating with the chamber, and a tube projecting from the second disk away from the chamber and communicating with the chamber. The tube is received and sealed within an end of the spout to make a leak-proof passage through the spout, tube, chamber, and slots. The spout assembly preferably includes a cap having a cylindrical side wall threaded to engage a threaded collar of a container and a top portion having a central hole to receive the spout therethrough and an annular gasket to form a seal alternately with the first or second disks.
