Abstract:
1. A pouring closure for a liquid packaging, comprising: a pouring stem having a radially projecting bottom edge; a threaded cover having a diameter larger than a diameter of said pouring stem; and, an elastically deformable ring element between said pouring stem and said threaded cover for providing elastic deformability for said pouring stem, said elastically deformable ring element having a ring surface running obliquely to a ring plane of said elastically deformable ring element, with an inner ring edge ending in a downwardly directed projection capable of being clipped over said pouring stem, with an outer ring edge of said elastically deformable ring element ending in an upwardly directed projection with an outer thread for screwing on said threaded cover, said elastically deformable ring element being elastically deformable for moving said elastically deformable ring element through a dead point between a first stable state and a second stable state with said first stable state being wherein said ring surface rises upwardly from said inner ring edge to said outer ring edge and with said second stable state wherein said ring surface is downwardly sloping, said pouring closure being elastically deformable into said first stable state and said second stable state for moving into an axial direction between a stable compressed position and a stable extended position.
