摘要: A lens case for disinfecting, cleaning, or storing contact lenses is described that provides a sealing and venting system for allowing the release of gas while avoiding liquid leakage. The venting means allows venting of gas when internal pressure increases, while maintaining a seal that is substantially gas and liquid-impermeable at other times. The lens case includes a cap securable to a container barrel and a mating cap. The venting of gas occurs via a tortuous-path mechanism resulting from appropriate surface roughness being produced on at least one of a pair of mating surfaces forming a seal between the cap and the container. In a preferred embodiment, a relatively roughened surface is produced on a cap flange that is in the shape of a circular lip downwardly extending from the inner surface of the cap. The mating surface of the cap flange sealingly presses against the rim portion of the container. The apparatus is particularly useful for the disinfection of contact lenses with hydrogen peroxide in which excess peroxide is decomposed into water and oxygen.
