Abstract: A cover-forming laminated structure interconnecting a plurality of containers, such as the base members of blister packages each of which is adapted to contain a hydrophilic contact lens in a sterile aqueous solution. More specifically, disclosed is an array of such containers which are interconnected by a single laminated multi-layered material constituting a covering label for the containers, wherein the material may be severed intermediate each of the containers along weakening lines formed by micro-perforations provided therein so as to provide a separate packaging arrangement. The material is imprinted over the surface extent thereof covering the plurality of containers with a specific pattern of indicia and legends configured with the intent of thwarting diverters upon separation of any of the packaging arrangements from the array, through visual evidence afforded by an inspection of the printing pattern.

Abstract: A method and apparatus for molding contact lenses by curing polymerizable compositions in suitably dimensioned molds using ultraviolet or other polymerization-inducing radiation and heat. The molds are moved along a source of radiation such that the intensity of the radiation to which the composition is exposed rises and falls several times, thereby achieving superior results by balancing the initiation and the propagation of the polymerization.

Abstract: An apparatus is provided for removing and transporting articles, such as contact lens sections from a manufacturing line to inspection and packaging stations. The lenses are deposited in a transparent plastic primary package which carries the lenses through the inspection station and becomes part of the primary package when a cover is sealed thereto. The invention includes various assemblies, including lens transfer assemblies, deionized water filling and removal assemblies, a water degassing assembly, a lens inspection assembly, and a lens package sealing assembly. The lenses are removed from pallets at a post hydration station, transported and spatially redistributed, and deposited in the primary packages disposed on a second set of pallets. The packages on the second set of pallets are filled with degassed deionized water. The contact lenses and packages are then transported to an inspection station.

Abstract: A method of and apparatus for employing a surfactant which is provided in order to assist in the release from each other of mold components of a multi-part mold employed in the molding of polymeric articles; for instance, such as a hydrophilic contact lens, upon completion of the molding process for the polymeric articles. The surfactant is applied in the form of a film or coating on surface portions of one of the mold components in order to facilitate the disengagement between the mold components during demolding, and the removal of excess polymeric molding material adhesively deposited on surfaces thereon.

Abstract: A computer control system for optimizing process parameters in an automated production line for producing contact lenses. The system comprises a plurality of process controllers for controlling one or more process stations of the production line, each of the controllers regulating a plurality of process control devices that each control specific production parameters used in the automated manufacture of contact lenses at the process station(s). An automated lens inspection device automatically evaluates each contact lens produced and generates inspection data for each contact lens, and a polling device polls each of the process controllers on a frequent basis to acquire process control data for each period. Further included is a correlating device for correlating the inspection data to the process control data and the contact lens data to optimize process parameters used in the production of contact lenses.
