Abstract
A blender collar assembly including a plunger moveable between a lower position where a blade assembly is prevented from coupling with a motor, and an upper position where the blade assembly is able to couple with the motor. The plunger includes an arm extending upward and having a u-shaped feature, and a protrusion associated with the u-shaped feature. The assembly further includes a concentric interlock ring rotating responsive to rotation of a blender jar. The interlock ring including a first portion engaging the u-shaped feature preventing the plunger from moving upward, a second gap portion not engaging the u-shaped feature enabling the plunger to move upward and downward within the collar, and a key engaging a protrusion of the blender jar as the plunger moves upward preventing the interlock ring from rotating while the second portion is rotationally aligned with the u-shaped feature.
