Abstract

A shaker particularly adapted for mixing the components of a liquid base material in a miniature size container includes a housing which carries a low voltage, high speed rotary output electric motor. The motor may be energized by batteries or by a domestic power source through an adaptor. An eccentrically offset bearing member attached to the motor rotates to reciprocate a connecting rod which in turn oscillates a cradle about its vertical axis. To mix the contents of the container, the container is set in the cradle in a horizontal orientation and held in such by a strap. This orientation not only promotes mixing by placing the contents in a gravitationally unstable position but subjects the contents to centrifugal and horizontal accelerating and deaccelerating forces during oscillation. Within a short time period the components are mixed to a homogeneous consistency.
