Abstract
An end closure for a shake and pour container is disclosed having a cover which is mounted on a canister type container. The cover has a rotor rotatably mounted on the cover. The cover has a break-away, hinged lid formed therein with the lid having a tab extending out from the lid beyond the hinge line. Upon applying a downward force on the lid, the lid may be broken away from the cover and rotated downwardly into the container along the hinge line thus opening the container. As the lid rotates down, the tab is also broken away from the cover and rotates upwardly above the level cover so as to be engaged by the rotor thereby to hold the lid in its full open position.
