  • Patent number: 7484879
    Abstract: Embodiments of the present invention are directed to a stirrer tool that includes a head component having a first plurality of projections extending substantially radially out from and substantially perpendicular to a longitudinal axis of a body portion. Head component may also have a second plurality of projections extending in a substantially distal direction away from a distal end of the body portion, and all of the projections may be made of a substantially stiff material that is flexible enough to be bent to fit through an opening in a container that is smaller in diameter than a diameter of the head component and stiff enough to mix viscous products. The projections may further be capable of being shortened by cutting off a selected length of the projections. The first plurality of projections may be configured to create a vortex mixing action and the second plurality of projections may be configured to reach and stir up sediment on bottoms and in corners of containers.
