Blender system with rotatable blade assembly

A blender system, comprising:

• a container, comprising:
• one or more container walls defining an interior volume of space forming a work chamber for processing one or more food products;
• a rotatable blade assembly disposed in the work chamber and operable for processing food contained within the work chamber;
• a keeper;
• and
• a slidable actuator shaft configured to slide between a first position and a second position;
• a lid configured to be positioned on a top of the container, the lid comprising:
• a hinged actuator lever configured to engage with the keeper to mechanically lock the lid to the container when pivoted from a first position to a second position;
• and
• a detent disposed in the hinged actuator lever and configured to intersect with the slidable actuator shaft of the container when the lid is positioned on the top of the container and the hinged actuator lever is pivoted to the second position;
• and
• a motorized unit disposed in a base configured to receive and couple with the container in such a way as to mechanically couple the motorized unit with the blade assembly, the motorized unit activated by a mechanical switch;
• wherein, when the detent of the lid intersects with the slidable actuator shaft of the container, the slidable actuator shaft slides from the first position to the second position in such a way as to mechanically intersect with and move the mechanical switch from an off position to an on position, thereby activating the motorized unit and causing the blade assembly to rotate.
