Abstract: Containers of two different capacities can be stacked on a closure which can be used with either container. The closure has a top panel with an inner stacking area contoured to receive and provide stability to a container having a bottom of one diameter, and an outer stacking area contoured to alternatively receive and provide stability to a larger container having a bottom of a different, larger, diameter.

Abstract: Apparatus for applying closures to containers held by grippers and moving in a row on a conveyor. The closures are fed from a supply into pockets on a star wheel which delivers them to closure carriers mounted to an applicator wheel which rotates in a plane parallel to and above the closure path of movement, about an axis perpendicular to that of the star wheel. Rotation of the closures carried by the carriers on the applicator wheel is synchronized with the rate of movement of the containers, and the closures are brought into converging alignment with the containers. The applicator wheel has optional means for pressing the closure partially or wholly to a final applied position on the containers, and/or for rotating them while still carried by the carriers to desired torque level.

Abstract: An improved sealing machine cap pickup is disclosed. The cap pickup is mounted on a sealing machine to feed closure caps onto filled containers being carried through the machine and to lightly turn the caps onto the containers. The pickup includes an improved universally mounted cap guide which directs the caps to a cap applying means such as spaced resiliently mounted and relatively deep cap applying belts or cap rotating friction shoes. Pressure backup plates are positioned above the cap rotating means for urging the caps downwardly at the correct rate as they are turned onto the moving containers.
