Abstract

The process includes several already-known phases, that is to say two or more drawing phases until the screw closure takes the required shape, a subsequent rolling phase and finally a phase for the insertion of any kind of sealing disk inside the closed top part of the closure. This process is characterized by the fact that it uses a special internal punch (p), equipped with two or more blades (1), located vertically, and most of all by the fact that it uses these blades (1) in the last drawing phase and furthermore by the fact that it uses said blades (1) on a line which goes from a known horizontal weakening line (2) to the lower edge of the closure. Thus it is possible to produce screw closures which are weakened vertically from the inside in that portion of the screw closure (4) which usually remains on the neck (6) of the bottle when the bottle is opened for the first time, so that this portion can be easily removed manually or mechanically by pushing downwards the abovesaid portion of the screw closure.
