Abstract
Abstract The invention relates to a bottle pick-up device where a rubber liner within a cup or holder is inflated by air so as to grip the top of the bottle with a metal insert being located within the liner so that inflation of the latter will only occur at its lower operative end instead of throughout its length thereby effecting a more positive gripping action between the top of the bottle and the rubber liner.
