Abstract
A hollow extension collar for a flowable material dispensing box, fits over a prior art dispensing box and can be locked in place to increase the enclosed volume incrementally. The incremental increase is determined by the height of walls from which the extension collar is formed. Multiple extension collars can be stacked on top of each other and filled with flowable material.
