There is provided a closure member for containers in which the closure member includes a closure wall, an aperture in the wall for dispensing a commodity through the closure member from the container, and a pair of cooperating tabs, one of which is adapted to be positioned exteriorly of the closure wall and the other interiorly in registry with each other. The outer closure member includes a movable gripping portion. The two tabs are joined together for movement about a fixed axis so as to go into and out of registry with the aperture; the inner tab is made of at least partially flexible material to permit inward bending into the body of a container to rupture a flexible inner sealing membrane. The improved closure device finds use in containers of different types and provides for an improved resistivity against tampering.
