A can end assembly formed from interconnected elements of a cover portion, a tear-shaped seal member and a pull member. This assembly encloses an end of a container, such as a beverage can. The cover portion has a dispensing opening and vent and a pivotable connection to one end of the seal member. The other end of the seal member is pivotably connected to the pull member. In a first position, the seal member will close the opening and will be beneath the pull member. Upon a slight lifting of the pull member, a seal between the seal member and opening will be broken. Continued movement of the pull member causes the seal member to rotate 180 degrees about its connection to the cover portion. During this movement, the pull member also rotates 180 degrees about its longitudinal axis and is displaced about 90 degrees relative to its initial orientation. This movement results in the seal member being positioned above the pull member and in these two elements being in an open, out of the way location to permit a consumer to empty the container. This movement may be reversed to temporarily reseal the container. In the open position, the seal and pull members may be temporarily locked beneath a flange partially surrounding the cover portion. A score line is provided beneath the cover portion to accommodate compression forces. A groove extends around the periphery of the cover portion to permit the can end assembly to snap onto the can body.
