Ophthalmic lens package with internal drainage member
An ophthalmic lens package comprises a shell having an internal cavity accessible through an opening in the shell and a drainage member that divides the internal chamber into an upper chamber and a lower chamber. The drainage member is permeable to aqueous liquids and is arranged to allow drainage of liquid from the upper chamber to the lower chamber. This arrangement of the ophthalmic lens package allows the consumer to retrieve the lens from the upper chamber without handling any significant amount of saline solution.
1. An ophthalmic lens package, comprising:
a shell defining an opening and having an internal cavity accessible through said opening;
dividing means secured to said shell for dividing said cavity into an upper chamber and a lower chamber, said upper chamber having an interior accessible through said opening, said dividing means allowing the permeation of aqueous liquid between said upper chamber and said lower chamber,
covering means comprising a foil/polymer laminate or coextrusion for covering said opening and forming a liquid-tight hermetic seal with said shell;
an opthalmic lens contained entirely within said upper chamber; and
a quantity of an aqueous solution contained within said cavity, said lower chamber having a volume sufficiently large to contain the entire quantity of said aqueous solution.
2. The package of claim 1 , wherein said dividing means is arranged to allow drainage of aqueous liquid from said upper chamber into said lower chamber.
3. The package of claim 2 , wherein said dividing means comprises a mesh.
4. The package of claim 2 , wherein said dividing means comprises a plastic member having perforations therethrough.
5. The package of claim 1 , wherein said covering means has an edge with a grippable tab.
6. The package of claim 1 , wherein said interior of said upper chamber is sized and shaped to contain an ophthalmic lens entirely within said upper chamber and said lower chamber has an interior that is sized to contain an aqueous liquid.
7. The package of claim 1 , further comprising a grippable handle.
8. The package of claim 1 , wherein said shell includes a rim which defines said opening, wherein said covering means a liquid-tight hermetic seal with said rim.
