Blender apparatus with safety interlock system

A vessel assembly for a blending device comprising:

• a vessel configured to hold a blending material within an interior of the vessel;
• at least one blade positioned within the interior of the vessel, wherein the at least one blade is configured to mix the blending material;
• at least one thermal detector positioned at least partially within the interior of the vessel to contact the blending material held within the interior of the vessel;
• a logic circuit element configured to electronically communicate with a base via at least one electrical contact when the vessel assembly is detachably secured to the base;
• and
• at least one compressive contact resiliently biased to a non-communicative configuration, wherein the at least one compressive contact is moveable to a communicative configuration when the vessel is secured to the base, and wherein the communicative configuration enables electronic communication between the logic circuit element and the at least one thermal detector, and
• wherein the at least one thermal detector is configured to detect a temperature of the blending material when the logic circuit element is in electronic communication with the base and the at least one thermal detector.

A vessel assembly for a blending device comprising:

• a vessel defining an open end and a closed end, wherein the vessel defines an interior between the open end and the closed end;
• a blade holder comprising:
• a housing configured to detachably secure the blade holder to the open end of the vessel and configured to detachably secure the blade holder to a base of the blending device;
• at least one blade configured to mix a blending material within the interior of the vessel;
• a logic circuit element configured to electronically communicate with the base of the blending device when the blade holder is detachably secured to the base;
• at least one thermal detector positioned to contact the blending material within the vessel when the vessel is secured to the housing;
• and
• at least one compressive contact resiliently biased to a non-communicative configuration, wherein the at least one compressive contact is moveable to a communicative configuration when the vessel is secured to the housing, and wherein the communicative configuration enables electronic communication between the logic circuit element and the at least one thermal detector, and
• wherein the at least one thermal detector is configured to detect a temperature of the blending material when the vessel is secured to the housing and when the logic circuit element is in electronic communication with the base and the at least one thermal detector.
