Definitions

  • the invention relates to a plastic screw cap for bottles, with a catchy raised thread, which has a single interruption between the beginning and end of the thread, which is located before reaching an angle of 360 ° calculated from the beginning of the thread (lower end of the thread).
  • a screw cap tilted in this way is held by the machine in this tilted position when unscrewed, so that a proper screw connection does not come about.
  • the problem is solved to remedy this situation and to design a screw cap of the type mentioned in such a way that it can be screwed on properly by the machine without further notice.
  • the interruption is preferably provided at a point at which the force for snapping the screw cap thread over the bottle neck thread when placing the screw cap, when it comes to lie at an angle, is on average the lowest.
  • the greatest inclined position of the screw cap is achieved when the thread start lies on the thread start.
  • the threads of the screw cap and bottle can have several turns, but the interruption is always provided only in the first turn of the screw cap thread.
  • Screw caps similar to the screw cap according to the invention are already known, but these screw caps are based on completely different problems.
  • a screw cap according to DE-A-3 006 481 is one with a two-start thread, which is placed in such a way that the threaded ends of the bottle neck and screw cap adjoin one another, the screw cap then snapping vertically over the threads of the bottle and is pressed into the end position.
  • this does not result in the problem on which the invention is based and therefore there is no interruption in the thread of the screw cap.
  • FIG. 1 shows a view from below of the open side of the screw cap and FIG. 1 shows a section through the screw cap.
  • the thread 10 of the screw cap with the The start of thread 12 is interrupted at point 14, the thread ends at the point of interruption 14 being chamfered as shown.
