Abstract: The container closure of the present invention is particularly useful for dispensing automobile engine oil from an inverted bottle or container where all of the fluid is normally emptied at one time. The opening in the container has a peelable, flexible seal which may be disposed beneath the normal cap or cover of the container. The seal has an elongated pull-tap which doubles back across the outer face of the seal and extends upwardly along the side of the container so that the end thereof may be grasped after the container is inverted and before the contents are discharged. When the end of the tab is pulled, the closure is peeled away from the container-opening, and the contents can be discharged without spilling.
