ABSTRACT:
Effective, easily manufactured seals for dispensing closures in which a spout is rotatably mounted on a cap can be created using an edge on an external surface of the cap to engage an end of the spout. This edge serves to create a seal. The end of the spout and the external surface adjacent to the edge have related cross-sectional configurations such that in all positions of the spout the end engages the edge in the same manner so as to form a seal.
