Abstract
A viscous material container evacuator comprises a chamber to hold a container and a plunger axially and slidably accommodated within the chamber to express material from the container; and at least one hinged closure that closes to define the chamber and to securely enclose the container; and at least one motor activated fastener that secures the closure around the container. A method to secure a closure of a viscous material container evacuator, comprises activating a motor drive shaft to drive a connected threaded shaft into a complimentary threaded channel of a clamp block that comprises an opposing nub wall; and driving the threaded shaft to impose upon a first lug of an evacuator and to foreshorten a distance between a head of the threaded shaft and the opposing nub to impose the nub against a second lug of a closure to secure the lugs together to secure the container.
