ABSTRACT:
A reclosable moveable valve stem actuated valve structure for an aerosol-type viscous fluid dispensing container. The valve structure is provided with an initially sealed internal seal and a valve stem operated internal seal removing component. The valve structure is preassembled before association with the container. The seal includes a seal plate and releasable bond. The seal removing component is associated with a moveable valve member. The moveable valve member is operated initially by movement of the moveable valve stem and causes the internal seal removing component to effectuate a release of the releasable bond, thereby opening the initially sealed internal seal.
