  • Patent number: 5620087
    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.

  • Patent number: 5555504
    Abstract: A production line tracking and quality control system and method thereof comprises a series of pallets for carrying one or more first contact lens mold halves or one or more complementary second contact lens mold halves throughout a contact lens fabrication facility. Each pallet of the series is transported on a conveyor device throughout the fabrication facility, and each pallet includes a unique identifying code. The fabrication facility includes one or more process stations and a control device provides real time monitoring of contact lens fabrication processes at the one or more process stations. The control device further includes a tracking device for identifying the unique code of each of the pallets at one or more process stations while continually receiving monitored process condition values at each station.
