ABSTRACT:
A blender cup apparatus comprising a rigid hollow base having a top wall, a bottom wall, a peripheral side wall; a open cup coupled to the top wall of the base; a lid removably secured over the cup; a battery removably disposed within the base for supplying electrical energy; a motor having a fixed stator coupled to the battery and base and a rotatable rotor extended upwards through the top wall and into the cup with the stator imparting rotational motion to the rotor; a propeller coupled to the rotor of the motor within the cup; a power switch extended from the base and coupled to the battery; and a pressure switch extended from the base and coupled between the motor and power switch, the power switch having an enabled orientation for allowing delivery of electrical energy to the pressure switch and a disabled orientation for preventing such delivery, the pressure switch having a depressed orientation for allowing electrical energy to be delivered to the motor and further having a released orientation for preventing such delivery.
