摘要：The present invention relates to a process and equipment for the fabrication ofglass containers with internally threaded neck and such containers. The plunger (6) isfrom the glass leaving an imprint corresponding to the mouth (M) of a bottle, whereinthe plunger has at least one helical groove (15) in its outside surface. During theextraction, the plunger is rotated around a longitudinal axis (X-X) performing a roto-translational motion to unscrew the plunger out of the partially solidified glass, leavingan internal thread in the mouth (M) of the bottle. The roto-translational motion for theextraction of the plunger is generated by: a linear actuator (30) acting on the plunger (6),thereby effecting a linear movement of the plunger (6) along said longitudinal axis (X-X),a guide body (14) wherein the plunger (6) is moved relative to the guide body (14) alongsaid longitudinal axis (X-X), and a helical guide (16, 17) coaxial to the longitudinal axis (X-X)

and being provided between said guide body (14) and said plunger (6) and transformingsaid linear movement effected by said linear actuator (30) on said plunger (6) into saidroto-translational motion of said plunger (6).
