Abstract: A manually operable rigid device defines a generally V-shaped groove opening onto an outer face thereof for closing a storage container in a multi-step process by bending a flexible, upstanding peripheral rim thereof over a margin of a central cover. A manually operable rigid device defines a wedge having a tip for opening a storage container in a multi-step process by unbending the previously bent rim thereof.

Abstract: An automatic bulk filling machine is provided having a container input end which includes a fill station for filling a container in accordance with weight or volume requirements followed by a lid dispensing and attachment station wherein the lids of the container are placed over the container in registry with the lip of the container and closed onto the bulk container by a piston cylinder combination having a lid pad for pressing and deforming the center of the lid onto the bulk container before press fitting the bulk container lid onto the bulk container which filled and sealed bulk container is then transferred to an optional labeling station and subsequently transferred to the output end of the conveyor to complete the automated filling, sealing and labeling operations for removal of the container from the automated bulk filling machine.

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.
