Abstract: A packaging container (1) for a contact lens comprises a shell (2). The shell (2) comprises a cavity (10) having a drop-shaped perimeter (12), and a flange (20) having a flat upper surface (22) extending around the drop-shaped perimeter (12) of the cavity (10) in an upper surface plane (24). The cavity (10) comprises a bowl portion (30) including an at least partially spherical section (32) for accommodating the contact lens, and a chamfer portion (40) surrounding the bowl portion (30). The chamfer portion (40) is arranged between the bowl portion (30) and the drop-shaped perimeter (12) of the cavity (10) and includes a tapered outlet section (42) forming a tip towards the flange (20) to facilitate removal of the contact lens from the cavity (10).
