Abstract:
A closure member for closing an open end of a container, said closure member comprising: a main body segment securable to edge portions of the container and defining a discharge port through which fluid may discharge from the container, said discharge port being selectively openable and closable by means of a flap segment slidingly mounted to the main body segment at a portion away from the periphery of the main body segment; said flap segment being moveable between a sealed position in which it sealingly covers the discharge port and an unsealed position away from the discharge port; and a resilient sealing segment disposed between the main body segment and the flap segment adjacent the discharge port; said sealing segment including a continuous liner, and said closure member including integral means for translating sliding motion of said flap segment into a sealing force directed toward said discharge port, whereby sliding of said flap segment from said unsealed position to said sealed position results in said flap segment sealingly engaging said discharge port.
