A hermetically sealed container is provided with a dispensing nozzle terminating in an aperture surrounded by locking lugs. A removable closure portion unitary with the dispensing nozzle and delineated by a frangible web that circumscribes the opening is provided as well so that the closure portion may be severed from the cap portion at the frangible web. An apparatus for fabricating such container is provided which includes a main mold assembly for molding the container body and dual seal mold assemblies for molding the container cap portion and container closure. The main seal mold assembly includes a top surface having a knife edge and an annular cavity. After the main seal mold assembly is closed during the molding process, a forming assembly including a mandrel is extended through the parison into abutting contact with the parison over the top surface of the main seal mold assembly. The mandrel is urged against the parison and the parison is urged against the knife edge and into the annular cavity for respectively forming the frangible web between the cap portion and closure portion of the container and molding the lugs on the dispensing nozzle of the container.
