摘要： 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.
摘要翻译：该方法包括几个已知的阶段，也就是说两个或多个拉伸阶段，直到螺旋封闭形成所需的形状，随后的滚动阶段，最后是用于将任何种类的密封盘插入封闭顶部的封闭顶部关闭。该过程的特征在于它使用特殊的内部冲头（p），其具有垂直定位的两个或更多个叶片（1），并且最重要的是在最后一个图中使用这些叶片（1）并且还通过以下事实，即在从已知的水平弱化线（2）到封闭件的下边缘的线上使用所述叶片（1）。因此，可以生产当瓶子首次打开时通常保持在瓶子的颈部（6）上的螺钉（4）的那部分内部从内部垂直减弱的螺丝封闭件，使得这样可以通过向下推动螺丝孔的上述部分来手动地或机械地部分地部分地移除。
