US Patent 12075941 Mixer with safety mechanisms

A blender for processing comestible matter includes a base with a motor, a blade assembly, and a container. The blender further comprises a first safety mechanism and a second safety mechanism. The first safety mechanism functions to ensure that the container is securely attached to the blade assembly before the blade assembly can be mounted to the base. The second safety mechanism functions to ensure the motor in the base can only be powered on when the container and the blade assembly are securely mounted to the base. The blender is operable by affixing the container to the blade assembly, and then the assembly to the base, such that both safety mechanisms are released to permit the motor to be activated.
