ABSTRACT:
A method of and apparatus for closing a container such that a container which has a sealed closure with a tab extending from it travels along a conveyor past a vacuum source which releasably secures the tab. As the container continues to move along the conveyor, the tab is pulled taut by the vacuum force. When the container reaches a predetermined position, it is raised off the conveyor with a yoke, the tab still being pulled taut by the vacuum force, and the top of the container, the sealed closure and the tab are pinched against a stop. At this position the tab is aligned, taut and clamped in place over the container opening so that a lid may be placed on the container.
