ABSTRACT OF THE DISCLOSURE A dispensing closure having a dispensing passage in an outlet spout is provided for use with an associated container. The unitary dispensing closure has a rigid base with a seal surface and latch surface, and a spout with a dispensing passage, a dispensing end and a first end connected with the base with seal means on the first end of the spout about the passage. The outlet spout is connected to the base by a hinge connected with an invertible diaphragm and by a second hinge interconnecting the invertible diaphragm to the base at a bi-sector plane. The diaphragm is is convexed configuration when the spout is in dispen- sing position and in concaved configuration then the spout is in sealed position, the spout in moving to sealed position pivoting about a pivot line, thus collap- sing the invertible diaphragm through the bi-sector plane to seat the seal against the base seal surface and urge the dispensing end of the spout to abut the base latch surface in sealing relationship. Abutment on both ends of the spout provides positive sealing.
