Title: Worm-type dispenser for rimmed containers

Abstract: A worm-type dispenser for rolled rim paperboard containers has a compression bead in the rim-engaging grooves of the worm to flex the central portion of the rim to render it more resilient so a cover having a rim contacting cylindrical skirt may be applied more easily.
