ABSTRACT:
A cup for use with a bottle to cover a threaded bottle cap having a roughened outer surface is formed with a plurality of inwardly projecting ribs which force-fit into engagement with the roughened surface of the bottle cap. At least two of the ribs are formed with a projecting seat for securing over the bottle cap. When the cup is seated in position on the bottle cap, the cup and bottle cap may be rotatably displaced as a unit to unscrew the bottle cap from the bottle. The cup can be separated from the bottle cap while the bottle cap remains on the bottle by pulling the cup away from the bottle cap, thereby allowing the bottle cap to be removed separately from the bottle.
