Zusammenfassung:A packaging arrangement for the sealed containment of at least one hydrophilic contact lens in a sterile aqueous solution, comprising at least one injection molded or thermoformed plastic base member (10;40) having a cavity (20;42;52) for containing a contact lens immersed in said solution, said base member (10;40) including a planar flange (12) extending outwardly about the periphery of the outer edge of said cavity (20;42;52), said cavity (20;42;52) consisting of an indentation extending from the plane of the upper surface of said flange (12), and a depending wall (48) projecting downwardly from a bottom surfact of said flange (12) closely inwardly of the peripheral edges (14,16) of said flange (12) and extending about at least portions of the periphery of said flange (12); characterised in that the upper surface (24) of said flange (12) has a raised surface area (22) extending about said cavity (20;42;52) for facing a superimposed cover sheet (36) in contacting relationship.
