A plastic container (B) for storing a hydrogel contact lens (L) in a liquid (S), the container (B) comprising: a cavity (C) and a substantially flat flange (1) that extends in a plane around the opening periphery of the cavity (C), and the flange (1) having a sealing area (2) round the circumference of the cavity (C). Furthermore, the sealing area (2) has a micro-texture pattern (20D). When sealing the container (C) with a flexible cover sheet (D) which is a laminate material having a metal foil layer and at least one polymer layer to form a storage package of the soft contact lens (L), the micro-texture pattern (20D) of the sealing area (2) engages a laminate foil cover (D) and displaces water beads present between the laminate foil cover (D) and the plastic container (B) in the sealing area (2) around the cavity (C) to form a heat seal. |
