Mixer

A mixer comprising:

• a container for holding one or more items to be mixed, the container comprising a top end and a bottom end, the bottom end configured to be placed on a flat surface, the top end comprising an opening, the container defining an inside volume;
• a generally disc-shaped lid configured to substantially cover the opening of the container,
• the lid comprising a hole through which the volume inside the container can be accessed,
• wherein the hole is disposed in the center of the disc and has sloped or curved sides;
• and
• a mixing assembly comprising:
• a housing configured to interface with the hole in the lid;
• a motor disposed within the housing;
• a power source configured to provide power to the motor;
• a switch for controlling the motor, the switch disposed on the housing;
• and
• a mixing element directly or indirectly attached to the motor, wherein the mixing element is sized to fit through the hole in the lid;
• wherein the switch is disposed on the housing in a location that causes the switch to be actuated when the mixing assembly interfaces with the hole in the lid and the force of gravity is applied to the mixing assembly;
• wherein the housing comprises at least a first end, wherein the first end is configured to interface with the hole in the lid, wherein the first end comprises a sloped or curved portion that interfaces with the sloped or curved sides of the hole in the lid.
