Abstract
A base member for a blister package for the containment of a contact lens includes a planar flange extending outwardly about a cavity for housing the contact lens. Proximate the peripheral edge of the flange, there is formed a continuous groove into which there is pressed the material of a flexible cover sheet of the blister package so as to clampingly engage the base member.
Claims21
A packaging arrangement for the sealed containment of at least one hydrophilic contact lens in a sterile aqueous solution;
- comprising:
- (a) at least one plastic base member having a cavity for containing a contact lens immersed in a sterile aqueous solution, said base member including a generally planar flange extending outwardly about the periphery of said cavity, said cavity consisting of an indentation extending from the plane of said flange of said base member and a continuous peripheral groove formed in the plane of said flange and extending closely inwardly of the peripheral edge of said flange, wherein a second indentation is formed in the surface of said flange intermediate said cavity and said peripheral groove;
- and
- (b) a flexible cover sheet superimposed over said base member and dimensioned to be detachably sealed to a surface area of said flange extending about said cavity and including said cover sheet having the portions thereof located in alignment with said peripheral groove depressed into said groove so as to form a clamping engagement with said flange coextensive with said peripheral groove.
