Abstract
A method for stacking and unstacking reusable plastic trays for storing and transporting beverage containers, such as twelve-ounce metal cans and two-liter PET bottles. When the tray is a can tray, the bottom surface of the floor has a pattern of protuberances and recessed areas therebetween. A loaded can tray is stacked on a similar tray therebeneath, such that the lower can rims fit into the recessed areas and the protuberances are positioned both inside of and outside of the rims thereby locating and locking the upper tray in place. To unlock the upper tray it is simply twisted so that the protuberances ride up their bevelled edges onto the rims and into a sliding position.
