An appliance for containing and venting fluid, typically for disinfecting contact lenses, includes a container body which has an access opening and a removable closure for the opening. A gasket is seated to form a normally liquid-tight seal between the container body and the closure, and the gasket means has a composition which is sufficiently resilient to at least partially deflect and unseat from the container body upon exertion against the gasket of elevated gas pressure developed within the container, for example, during a disinfection process. The pressurized gas can then be vented past the unseated gasket which forms a vent passageway between the closure and the container body, after which venting the gasket redeflects to reseat and seal against the container body to prevent any subsequent leakage of fluid from the container body. As a result, the gasket serves not only as a closue seal, but also as a one-way check value for release of pressure, for example, during the disinfection process so that the alternative sealing and venting by the gasket are performed repeatedly.
