Abstract
Blender and food processing devices dampen impact forces between a blending blade and a blending jar. One blender includes a blender base and a blending jar that has a seal opening. A blending blade assembly in the jar includes a blending blade, a jar shaft attached to the blending blade and extending through the seal opening, a circular motion guide positioned around the jar shaft, and a jar seal positioned between the circular motion guide and the seal opening. The jar seal prevents contact between the circular motion guide and the seal opening and dampens forces induced by relative motion between the seal opening and the blending blade, jar shaft, and/or circular motion guide. The dampening may reduce wear or damage to the jar and may improve quality of the blending jar and blade assembly.
