ABSTRACT:
A bottle closure-cup assembly for use with a bottle having a rotatably removeable cap is provided. The assembly includes a cup having an inner cylindrical collar extending from the cup base and spaced apart from the cup wall. The collar includes a plurality of inwardly facing axial ribs and a plurality of transverse retaining lugs for engaging the cap. Support fins extend between the cup wall and the collar for strengthening the assembly. When the cup is positioned on the cap, the cup and cap may be rotatably displaced as a unit to remove the cap as the cap remains by pulling the cup away from the bottle, thereby allowing the cap to be removed from the bottle separately.
