Contact lens package

Abstract

This invention provides a disposable contact lens package comprising a base having a top surface and a recessed well having a perimeter in the top surface, said well for holding said contact lens therein, said top surface comprising a raised seal volume surrounding said perimeter of said recessed well said raised surface having a cross-sectional shape comprising two linear sides that intersect the horizontal plane at angles alpha and beta, respectively, wherein angles alpha and beta independently have values from 125 to 170 degrees; and wherein said package further comprises a removable lidstock sealed to said raised seal volume.

         4 . The contact lens package of  claim 1 , wherein the distance of the raised seal volume from the perimeter of the well is from 0 to 6 mm.  
     
     
         5 . The contact lens package of  claim 1 , wherein the height of the raised seal volume from the flange of the package is from 0.1 mm to 0.3 mm.  
     
     
         6 . The contact lens package of  claim 1 , wherein angles alpha and beta independently have values from 145 to 165 degrees.  
     
     
         7 . The contact lens package of  claim 1 , wherein angles alpha and beta independently have values from 155 to 165 degrees.  
     
     
         8 . The contact lens package of  claim 1 , wherein the distance of the raised seal volume from the perimeter of the well is from 1 to 5 mm.  
     
     
         9 . The contact lens package of  claim 6 , wherein the distance of the raised seal volume from the perimeter of the well is from 1 to 5 mm.  
     
     
         10 . The contact lens package of  claim 1 , wherein the height of the raised seal volume from the flange of the package is from 0.12 mm to 0.24 mm.  
     
     
         11 . The contact lens package of  claim 6 , wherein the height of the raised seal volume from the flange of the package is from 0.12 mm to 0.24 mm.  
     
     
         12 . The contact lens package of  claim 7 , wherein the height of the raised seal volume from the flange of the package is from 0.12 mm to 0.24 mm.  
     
     
         13 . The contact lens package of  claim 1 , wherein the height of the raised seal volume from the flange of the package is from 0.14 mm to 0.16 mm.  
     
     
         14 . The contact lens package of  claim 6 , wherein the height of the raised seal volume from the flange of the package is from 0.14 mm to 0.16 mm.  
     
     
         15 . The contact lens package of  claim 7 , wherein the height of the raised seal volume from the flange of the package is from 0.14 mm to 0.16 mm.  
     
     
         16 . The contact lens package of  claim 15 , wherein the linear sides are independently from 0.1 mm to 0.65 mm in length.  
     
     
         17 . The contact lens package of  claim 15 , wherein the overall width of the raised seal volume is from 1.16 mm to 2.3 mm.  
     
     
         18 . The contact lens package of  claim 1  further comprising a rounded surface from said linear sides.  
     
     
         19 . The contact lens package of  claim 18  wherein said radius of said rounded surface is from 1 to 10 mm.  
     
     
         20 . The contact lens package of  claim 17 , further comprising a rounded surface between said linear sides wherein said radius of said rounded surface is from 1.5 to 6 mm.
