Abstract: A bottled beverage vending machine storage column modified by including a controlled containment system to dispense irregularly shaped bottles having spherical surface areas from a dispenser tray at the bottom of the column for discharge of the bottled beverages from a collection door without damage to the bottles. The controlled containment system includes a pair of opposed bottle neck guide tracks, one of which is adjustable in width to provide for temporary holding of the bottles in suspension and the other of which includes removable and telescopic segments, to keep the bottles from turning sideways when the bottles are stacked alternately, neck to bottom in a stack.
