The invented blister pack comprises a base portion (B) and a cover layer (D). The base portion (B) comprises a hollow chamber (C) that contains a soft hydrophilic contact lens (L) and a sterile aqueous preserving solution (S), and a substantially flat flange (1) that extends right round the outside of the hollow chamber (C). The cover layer (D) is releasably sealed to the flange (1) in a sealing zone (2) that extends right round the circumference of the hollow chamber (C). The flange (1) comprises a grip region (3) that extends at least from one side of the hollow chamber (C) beyond the sealing zone (2) and is covered at least partially by a second grip region (4) of the cover layer (D) but is not sealed thereto. The hollow chamber (C) comprises a dish-shaped main chamber (11) and, adjoining the side of that main chamber (11), a secondary chamber (12) in the shape of a channel tapering on all sides away from the main chamber (11), the main chamber (11) making a smooth transition into the secondary chamber (12), and the main chamber (11) and the secondary chamber (12) together having a drop-shaped contour (14) in the plane (E) of the flange (1), the tip (14a) of which contour (14) is directed towards the first grip region (3) of the flange (1). Provided in the first grip region (3) of the flange (1) is an oval opening (15) by means of which the overlying second grip region (4) of the cover layer (D) can be lifted from the flange (1). A front support element (16) that is angled with respect to the plane (E) of the flange (1) is arranged in the first grip region (3) of the flange (1). Angled grip elements (18, 19) for facilitating the handling of the blister pack are arranged at the edge of the flange (1) on both sides of the hollow chamber (C). The base portion (B) is so shaped that the blister packs can be nested in pairs with their undersides one inside the other, in each case the hollow chamber (C) of one blister pack lying in the first grip region (3) of the other blister pack. |
