ABSTRACT:
A dispensing spout includes a tubular body having axially opposite ends of which one end has a cutting edge for penetrating the wall of a container from which a product is to be dispensed and an opposite end of the tubular body has a groove defined by an axial groove portion and two generally radial grooved portions each ending in a blind wall. A ring is freely slidably received on the tubular body and has a tab in registration with the groove. A gasket is sandwiched between the retaining ring and the thread of the tubular body. The tab of the ring is engaged in one of the radially grooved portions for threading the tubular body into the container after the wall has been punctured. The tab is further received in the other of the radial grooves for compressing the gasket and effecting the seal between the dispensing spout and the container.
