Abstract: A unitary tray molded to substantially finished form of conventional fibrous pulp or foamed plastic material for use, for example, as an inexpensive disposable carry tray in fast food and beverage establishments, the tray featuring one or more sockets for holding a slightly tapered or straight walled beverage cup or other such container. The improved container holding socket has been developed to accommodate and stabilize not one but a range of sizes of containers, for example from the narrower size juice "glasses" to the several intermediate sizes of soft drink and coffee cups to the wider size milkshake containers. The container holding socket comprises preferably three stabilizing shoulders positioned in spaced apart opposition to each other at a height significantly above the bottom of the socket, to hold the wider sizes of containers and support them against tipping.
