Abstract
A dual convex flask is of one-piece integrally molded plastic construction. The flask has opposed front and back walls each with a convex label panel area at a first radius of curvature and axially spaced bumpers that extend outwardly from opposite ends of the panel area. Opposed substantially flat sidewalls connect adjacent side edges of the front and back walls. The bumpers on each of the front and back walls have a second radius of curvature that is greater than the first radius of curvature, such that the bumpers have a radial depth perpendicular to the label panel area which is greatest at the ends of the bumpers adjacent to the sidewalls and least at the center of the panel area.
