ABSTRACT:
Suction cups for storing hard or semi-rigid, gas permeable contact lenses in soaking solutions are provided with rims characterized by substantially horizontal ledges which are at least as wide as the sides of the suction cup are thick. The suction cups are made by injecting a plastic forming material into a stemmed suction cup mold and contacting the plastic forming material against the adjacent convex head and ledge of a cylindrical molding pin whose cylindrical body diameter is greater than the diameter of the base of its convex head. A ledge is thus formed between the base of the convex head and the outside surface of the cylindrical body so that the resulting suction cup has a substantially horizontal ledge as its upper rim.
