    Abstract: A dispensing device primarily for rollable articles, such as cans or bottles, including an inclined runway for supporting the articles in series for gravitational movement toward a discharge end. A door for opening and closing the discharge end having a front barrier and a bottom barrier merged to form a transversely disposed, arcuate trough. When the door is in closed position, the trough receives the leading article, and when the door is in open position, the bottom barrier member moves between the leading article and the next adjacent article to permit removal of the leading article and to stop movement of the remaining articles on the runway.
