Apparatus for disinfecting contact lenses having improved vent means

摘要

An ophthalmic lens disinfection apparatus, including a container and a mating cap, the apparatus having an improved seal and vent means for venting gas generated within the apparatus. The vent means is an integral part of the disinfection apparatus which allows venting of gas when internal pressure increases, while maintaining a seal which is substantially gas and liquid- impermeable at other times. The seal is defined by the interference mating of a flexible periphery on a container with a rigid mating rim on a cap. The apparatus is particularly useful in the disinfection of contact lenses with hydrogen peroxide in which the excess peroxide is decomposed into water and oxygen.
