ABSTRACT:
The invention comprises a reusable closure for temporarily sealing a container to prevent escape of liquid and gas from the container with the closure having a molded, one-piece housing having internal threads for securing the housing to a container and a spout for discharging materials therefrom and an integral tapered sealing ring to prevent materials from escaping from the housing with the housing including a frusto-conical seat for engaging a valve stem with flared skirt for temporarily sealing liquid and gas within the container and a resilient push top, located on top of the housing for finger access by the user with the valve stem connected to the underside of the push top, valve stem axially displaceable to permit sealing and resealing of the skirt against the frusto-conical seat in the housing and the resilient push top providing a restoring force to return the valve stem and skirt to a closed condition where the fluid pressures within the container coact with the skirt to prevent escape of liquids or gasses past the skirt.
