Package for contact lens containers

The blister pack comprises a base portion and a cover layer. The base portion comprises a hollow chamber that contains a soft hydrophilic contact lens and a sterile aqueous preserving solution, and a substantially flat flange that extends right round the outside of the hollow chamber. The cover layer is releasably sealed to the flange in a sealing zone that extends right round the circumference of the hollow chamber. The flange comprises a grip region that extends from one side of the hollow chamber beyond the sealing zone and is covered by a corresponding grip region of the cover layer but is not sealed thereto. The hollow chamber comprises a dish-shaped main chamber and, adjoining the side of that main chamber, a secondary chamber in the shape of a channel tapering on all sides away from the main chamber, the main chamber making a smooth transition into the secondary chamber, and the main chamber and the secondary chamber together having a drop-shaped contour in the plane of the flange, the tip of which contour is directed towards the grip region of the flange. Provided in the grip region of the flange is an oval opening by means of which the overlying grip region of the cover layer can be lifted from the flange. A support element that is angled with respect to the plane of the flange is arranged in the grip region of the flange. An angled grip element or facilitating the handling of the blister pack is arranged at the edge of the flange on both sides of the hollow chamber. The base portion 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 of one blister pack lying in the region of the grip region of the other blister pack. The blister pack is extremely handy, space-saving and stable, requires only an extremely small amount of preserving solution and enables the contact lens it contains to be removed especially easily.
