Description of the invention (!) The scope of the invention The present invention relates to contact lens packages, especially disposable contact lens packages commonly referred to as blister packages. BACKGROUND OF THE INVENTION Soft hydrogel contact lenses have become increasingly popular since their introduction in the 1970s. These contact lenses are generally packaged in a hydrated state and contained in a storage solution. Currently, many contact lenses are packaged in a disposable plastic cover package with an aqueous solution for preservation. Examples of shroud packages can be found in U.S. Patent Nos. 4,691,820, 5,524,419, 5,578,331, 5,649,410, and 5,722,536; each of the above patents is incorporated herein by reference in its entirety. . The base of a hood package may be part of the original contact lens mold or a separate molded base. For an example of using a mold as part of a package, see U.S. Pat. Nos. 5,036,971, 5,143,66, 5, Shu, 062 and 5,573, printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs Bluff, the above patents are incorporated herein by reference in their entirety. In all of the above package types, the base that holds the contact lens and any water for preservation> Whether it is a stand-alone molded base or the original contact lens mold, the mouth of the knife is sealed by a flexible cover. The cover is usually a laminated foil that can be pulled by a user to access the eye sockets placed in the base. Generally, this cover is sealed in the area surrounding the base to receive the contact lens. This base sealing area is usually a flat surface area, or a raised two iridium-shaped flat surface, such as described in U.S. Patent No. 5,722,536. It was found that this flat surface, whether or not it is raised, may be in the
