Bottle closure cap for two-component packages

摘要

A bottle closure cap for two-component packages is formed with a collar extending from the bottom of a cup-shaped cap which has a bottle screw-on thread on the inner wall of the cup. The collar connects via a thread which is directed opposite the bottle-screw-on-thread, to a beaker which can be brought over projections seated on an outer side of its beaker cylindrical wall into a non-rotatable but axially displaceable coupling engagement with the inner wall of a bottle neck. A front end of the collar comes into form-locked engagement by an annular groove on the bottom of the beaker.
