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.

A dispensing spout comprising a generally tubular body defining a passage therethrough between axially opposite end portions of said tubular body, means at one axial end portion of said tubular body for penetrating a wall of a container within which is packaged a dispensable product, said tubular body including thread means for connecting said tubular body to said wall upon rotation of said tubular body, a ring surrounding said tubular body in free axial reciprocal sliding relationship thereto, and said ring including first means in external free axially reciprocal sliding relationship and rotating relationship to said tubular body and cooperative with second means upon said tubular body for initially imparting rotation to said tubular body thereby threading said thread means to an associated container wall followed by a relative axial movement between said tubular body and said first means and thereafter a relative rotational movement between said tubular body and said first means to clampingly connect said tubular body to an associated container wall.
