A cylindrical, vertically extending container having an interior, spring-pressed pressure head is adapted resiliently to constrain inverted stacks of paper cups upwardly against a plurality of radially-inwardly-extending, downwardly-directed, arcuate leaf springs, the upper ends of which springs are secured against upper end portions of the container in peripherally-spaced relation, and the lower ends of which springs extend through side openings in the container and are attached to an adjusting collar slidably disposed with respect to the outside of the container. A screwdriver adjustment mechanism serves to positionally adjust the adjusting collar with respect to the container to provide for various degrees of inward flexure of the springs for accommodating a wide variety of sizes, selectively, of paper cups to be dispensed.
