ABSTRACT:
A flexible, generally tubular shaped spout device for use in dispensing fluids from containers having threaded or unthreaded openings. A hemispherical flange is included on a lower open end of the spout device which allows for flexible enlargement of a sealing ring upon compression of the external surfaces of the flange. Dimensions of the flexible spout are such that the spout may be centrally folded and latched in a retaining ring to create a seal between the lower open end and the upper open end of the spout.
