Abstract
A handheld shaker with a reciprocating agitator, comprising a mixing vessel that operatively contains a guide rod that runs from one end of the vessel to an opposite end of the vessel.

The shaker also uses a hollow agitator frame that operatively reciprocates from the one end of the vessel to the opposite end, and thereby mixes fluid contained within the vessel. A reciprocating agitator is also disclosed.

A handheld shaker with reciprocating agitator, comprising:
- a mixing vessel, operatively containing a guide rod that runs from one end of the vessel to an opposite end of the vessel, and that is operatively connected to both such ends;
- and
- a hollow elastic agitator frame that operatively reciprocates from the one end of the vessel to the opposite end, and thereby mixes fluid contained within the vessel;
- wherein the hollow elastic agitator frame has a primary axis of elasticity along a single entire at rest vertical length, and the hollow elastic agitator frame comprises at least one internal attachment member that secures every segment of the single entire at rest vertical length of the hollow elastic agitator frame firmly to the guide rod, which minimizes sideways distortion and movement of the entire vertical length of the agitator frame.
