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 mixing vessel is operatively connected to both such ends. 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.

Claims

1. 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;

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.

2. The shaker of claim 1 wherein the agitator frame has an internal attachment member that operatively attaches the frame to the guide rod and operatively slides along the guide rod.

3. The shaker of claim 2 wherein the agitator frame can slide onto, and off of, the rod.

4. The shaker of claim 1 wherein the agitator frame has an external mixing member, wherein the external mixing member and the internal attachment member are concentric coils.

5. The shaker of claim 4 wherein the concentric coils are made from one continuous piece of material.

6. The shaker of claim 4 wherein the agitator frame is diamond, circular, spherical, cube, polyhedral, or pyramid-shaped.

7. The shaker of claim 1 wherein the guide rod is substantially solid.

8. The shaker of claim 1 wherein the agitator frame operatively has a primary axis of elasticity parallel with the guide rod, and along which the frame contracts when it hits one of the vessel ends.

9. The shaker of claim 8 wherein the agitator frame has an external mixing frame comprised of concentric coils, wherein multiple coils can operatively touch the end of the vessel when the frame contracts against the end.

10. The shaker of claim 8 wherein the agitator frame has a spring that operatively impacts the vessel'"'"'s ends only at its ends.

11. A reciprocating agitator, comprising:

a hollow agitator frame that operatively reciprocates from one end of a mixing vessel to an opposite end of the mixing vessel, and thereby mixes fluid contained within the vessel;

wherein the mixing vessel operatively contains a guide rod that runs from the one end of the vessel to the opposite end of the vessel, and that is operatively connected to both such ends.

12. The agitator of claim 11 wherein the agitator frame has an internal attachment member that operatively attaches the frame to the guide rod and operatively slides along the guide rod.

13. The agitator of claim 12 wherein the agitator frame can slide onto, and off of, the rod.

14. The agitator of claim 11 wherein the agitator frame has an external mixing member, wherein the external mixing member and the internal attachment member are concentric coils.

15. The agitator of claim 11 wherein the agitator frame operatively has a primary axis of elasticity parallel with the guide rod, and along which the frame contracts when it hits one of the vessel ends.

16. The agitator of claim 15 wherein the agitator frame has an external mixing frame comprised of concentric coils, wherein multiple coils can operatively touch the end of the vessel when the frame contracts against the end.

17. The agitator of claim 15 wherein the agitator frame has a spring that operatively impacts the vessel'"'"'s ends only at its ends.
