Abstract: A method and system for providing a modular container for a utility trailer comprising a bottom panel assembly; an upper panel assembly stackable on the bottom panel assembly, the upper panel assembly and the bottom panel assembly defining a cavity therein when the modular container is in a disassembled state; a plurality of panels being substantially containable within the cavity and being removably securable to the bottom panel assembly and the upper panel assembly when the modular container is in an assembled state to define a substantially enclosed volume; and the bottom panel assembly defining a pair of slots sized to engage a portion of the utility trailer and a pair of apertures larger than the pair of slots sized to engage a portion of a fork lift.

Abstract: A self-service beverage distribution system includes a piping network with refrigerated tubing for transporting beverages, such as beer, from at least one source to at least one output. A drinker purchases a magnetic card which represents a predetermined quantity of beer, and which specifies which beer sources the drinker can have access to. A flow meter measures how much beer the drinker dispenses, and the quantity of beer represented on the card is decreased accordingly.
