Abstract: A new mixing device for mixing solids and medium to highly viscous food ingredients with liquid in a shaker bottle. The mixing device has an agitator with a center portion and distal portions of larger diameter than the center portion. The agitator is insertable within a hand-held, shakeable container. The agitator is composed of a framework arranged to provide voids to allow for flow of liquids, powders, and other materials into and out of portions of the agitator. The mixing device also has a weighted member attached adjacent to or within the center of the agitator that increases the momentum of the mixing device when in operation. The weighted member may have a metal core and polymer exterior.

Abstract: A new mixing device for mixing solids and medium- to highly viscous food ingredients with liquid in a shaker bottle. The mixing device has a generally dumbbell-shaped agitator insertable within a hand-held, shakeable container. The agitator is composed of a framework arranged to provide voids to allow for flow of liquids, powders, and other materials into and out of portions of the generally dumbbell-shaped agitator. The mixing device also has a weighted member attached adjacent to or within the center of the generally dumbbell-shaped agitator that increases the momentum of the mixing device when in operation.
