Containers having at least one container sidewall, such as with a tubular cylinder or tubular polygon shaped cross-section. An external operator applies force through the container wall using a non-contacting force coupling which transmits through the sidewalls. The non-contacting forces may be by magnetic coupling, electrostatic coupling, electromagnetic coupling or possibly other non-contacting force couplings. In manually powered units the magnetic coupling is currently preferred.
