Abstract
A case for disinfecting, cleaning or storing contact lenses is described that provides a venting system for discharging gas therefrom without significant liquid discharge. The case includes a cap securable to a container, having an inner surface including a hollow pedestal with its open distal end extending into the container. The end of the pedestal adjacent the inner cap surface encompasses an aperture through said cap for venting and discharging of gas to the environment. A gas and liquid impermeable gasket fits inside the hollow end of the pedestal adjacent the aperture area, permitting venting of gas but not liquid through the adjacent aperture. A support for holding and positioning contact lenses in the container includes a post that is fitted into the distal end of the hollow pedestal, wherein the pedestal and post are provided with a channel therethrough to permit gas to escape from the container through the gasket and adjacent aperture.
