<p>A pouring nozzle with a flange and an internal thread and an external thread, and also a cutting element having an upper rim and a lower rim formed with teeth. A screw cap with catches acts on catches of the cutting element. To make fitting easier, the cutting element and the pouring nozzle are produced as a one-piece semifinished product, wherein the cutting element is connected to the lower rim by weakened bridges so that the lower rim of the cutting element lies in a plane with the upper rim of the pouring nozzle and the teeth are protected in the pouring nozzle. This structural design allows an easy fitting which also reduces the reject rate.</p> |
