Abstract
A remote-control apparatus for opening or closing a container is disclosed, which includes a rotary drive mechansim, an operable shaft driven by the drive mechanism, and a drive wheel mounted on the operable shaft, the drive wheel being held on the operable shaft by a collar. The drive wheel has at one end teeth members which engage notches formed in the peripheral edge of a valve wheel of the container. When the drive mechanism is activated, the operable shaft turns the drive wheel, which causes the valve wheel of the container to turn, thereby causing the valve of the container to either open or close.
