Packaging system
A packaging system for hydrating sterile devices without comprising the integrity of the sterilization. The packaging system may include an enclosure for enclosing a device requiring hydration, a container containing a hydrate, a base located within the interior of the enclosure and an activating member located within the interior of the enclosure. The container and the device may be located within a receptacle. The receptacle may rest on the base and the activating member may be affixed on top of the receptacle. A force may be exerted on an exterior portion of the enclosure such that the activating member pushes on the receptacle and crushes or ruptures the container. The hydrate located within the container is then released to the device, thereby hydrating the device without breaking the seal of the enclosure. The sterilized environment is therefore maintained and the device is hydrated.

The present invention is directed to new and improved packaging systems for storing ophthalmic devices such as contact lenses and to methods for packaging such ophthalmic devices with aqueous packaging solutions to improve the comfort of the lens during wear. In particular, the present invention is directed to a packaging system for storing an ophthalmic device in an aqueous packaging solution comprising an anionic polymer and a non-ionic polyol. Such solutions can be retained on the surface of an unused lens for extended periods of time, resulting in surface modification that persists in the eye, which may provide significant improvement in the wetting properties of fresh contact lenses used for the first time and, moreover, even several hours after lens insertion, preventing dryness and improving lubricity.

Liquid delivery system with horizontally displaced dispensing point
A method and apparatus is provided for the efficient and controllable delivery of cryogen liquid droplets into thin walled containers before they are sealed, the pressurization of the sealed container caused by the evaporation of the liquid cryogen causing the walls of the container to stiffen. Discharge of the droplets immediately upstream of the container sealing station is facilitated using a horizontal displacement assembly to transport metered droplets from a liquid dosing unit to the point of injection above the container. The horizontal displacement assembly may be provided with internal heaters to prevent freeze up, and a sensor to confirm droplet discharge. It may also be provided with a separate source of heated nitrogen gas, which can be used to back purge the dispensing unit should it become clogged, to melt any frozen liquid occlusions which may have formed in the cryogen supply line. In one embodiment, the solenoid used to actuate the piston regulating the opening and closing of the needle valve, which meters the dispensing of droplets, is mounted in thermal contact with said piston, this placement of the solenoid serving to cool the piston and thus prevent overheating in the case of rapid cycling.

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. After inspection, the lenses and packages are transported to a water removal assembly, and then to another transfer assembly. This transfer assembly separates those lenses which passed inspection from those which did not, and places those that did in a consolidating assembly. The lenses and packages are then filled with saline solution and a foil label is then sealed thereto to form the primary package.
