There is described a stopper remover for automatically removing a stopper in a container, the remover comprising first mechanism for gripping the container against rotation, second mechanism for gripping the stopper, and a drive for rotating the second mechanism about an axis while the second mechanism grips a stopper. The remover features an engaging assembly for frictionally engaging a stopper while the rotating drive rotates in only one direction, the engaging assembly comprising an annular ring and extending from the inside of the ring, a plurality of spikes terminating in points disposed generally in an annular surface inside of the ring and constructed to engage a stopper, the spikes being mounted on the ring so as to be non-radially aligned. The result is that the spikes positively grip the stopper only if the ring is rotated in the one direction, and slip off the stopper when the rotating drive rotates in a direction opposite to the one direction.
