ABSTRACT:
A cover for a valved dispensing closure prevents the valve from opening while the cover is disposed on closure. The cover's central projection prevents flaps formed in the valve from opening, and the cover's outer projection prevents the flexible valve head from moving or inverting. The cover may also have projections that project inwardly from its skirt. The cover projections interact with mating projections formed on an exterior of the closure, and a lower end of the skirt may be disposed into an annular groove in the closure, to enhance a seal between the closure and the cover.
