Abstract:
1. A system for aiding the visual matching of containers having diverse openings with corresponding lids comprising: a plurality of rectangular open top containers having bottom walls and peripheral upstanding walls terminating in different sized openings, the bottom walls of the containers including a geometric planar pattern which is unique to the size of a particular opening; and a plurality of rectangular lids with at least one of the lids sized to match the opening in each container of a given opening size, the matching lid having a geometric pattern on the top wall thereof which corresponds to the pattern on the bottom wall of the corresponding container of the given opening size; wherein the peripheral walls of each container are canted outwardly at a small angle (θ) of about 1° to 7° so that bottom walls of all containers of the same size of opening are of the same dimensions to accommodate the stacking of the containers; wherein the peripheral walls of each container are slightly convex following a radius of curvature (r) within the range of about 40″ to 120″; and wherein the peripheral walls of the containers terminate in a flat sealing surface and wherein the lids define a downwardly facing cavity following the contour of the sealing surface of the associated containers and further including a removable gasket disposed in the cavity.
