A pitcher has a container for containing liquid and a mixing device disposed at least in part within the container. The mixing device has a shaft adapted for translation relative to the container. An agitating member is connected to the shaft for conjoint translation therewith relative to the container to agitate the liquid in the container. A stop is disposed on the shaft to limit translational movement of the shaft and the agitating member.

1. A pitcher for mixing a liquid solution, said pitcher comprising a container for containing liquid, a lid releasably securable on the container, and a mixing device disposed at least in part within the container, the mixing device comprising a shaft adapted for translation and rotation relative to the container, an agitating member connected to the shaft for conjoint translation and rotation therewith relative to the container to agitate the liquid in the container, and a stop disposed on the shaft to limit translational movement of the shaft and the agitating member, the stop being spaced from the agitating member and the lid and selectively movable along the shaft. 2. The pitcher as set forth in claim 1 wherein the stop has a central opening adapted to accommodate the shaft therethrough. 3. The pitcher as set forth in claim 2 wherein the stop has an inner wall at the central opening and a rib extending inward of the opening to engage the shaft for maintaining the position of the stop on the shaft. 4. The pitcher as set forth in claim 3 wherein the shaft includes a groove for receiving the rib of the stop to releasably secure the stop along the shaft. 5. The pitcher as set forth in claim 1 wherein the stop is located on the shaft to contact the lid upon translation of the shaft to thereby limit translational movement of the shaft and the agitating member relative to the container. 6. The pitcher as set forth in claim 1 further comprising a grip operatively connected to the shaft for manually translating the shaft relative to the container. 7. The pitcher as set forth in claim 1 wherein the agitating member connects to the shaft such that a passageway is formed between the agitating member and the shaft for allowing liquid to flow through that passageway during translational movement of the shaft. 8. A pitcher for mixing a liquid solution, said pitcher comprising: a container for containing liquid;a mixing device disposed at least in part within the container, the mixing device comprising a shaft adapted for translation relative to the container, and an agitating member connected to the shaft for conjoint translation therewith relative to the container to agitate the liquid in the container, the agitating member being further adapted for rotation within the container in response to translating movement of the shaft, the shaft having at least one fin that spirals helically around the shaft;a lid having a recess, an opening in the recess, and at least one key slot extending radially outward from the opening, the shaft being received through the opening such that the at least one fin of the shaft is received in the at least one key slot, anda grip operatively attached to the shaft, the grip being selectively moveable between an operative position and a stowed position wherein at least a portion of the grip is received within the recess in the lid, the grip engaging the lid in the stowed position. 9. The pitcher as set forth in claim 8 wherein the shaft is adapted for rotation upon translation of the shaft, the agitating member being operatively connected to the shaft for conjoint rotation therewith. 10. The pitcher as set forth in claim 9 wherein the at least one fin comprises a pair of fins that spiral helically around the shaft. 11. The pitcher as set forth in claim 10 wherein the at least one key slot comprises a pair of key slots extending radially outward from opposite sides of the opening, the shaft being received through the opening such that the pair of fins of the shaft are received in respective key slots. 12. The pitcher as set forth in claim 8 wherein the agitating member includes a hub and a plurality of blades extending outward from the hub. 13. The pitcher as set forth in claim 12 wherein the agitating member further includes an annular support spaced from the hub and interconnecting each of the blades. 14. The pitcher as set forth in claim 12 wherein each of the blades is disposed at an angle with respect to the hub. 15. The pitcher as set forth in claim 14 wherein each of the blades is curved along its length so that the angle of the blade at the location where the blade contacts the hub is substantially different than the angle of the blade at a location remote from the hub. 16. The pitcher as set forth in claim 8 wherein the agitating member connects to the shaft such that a passageway is formed between the agitating member and the shaft for allowing liquid to flow through that passageway during translational movement of the shaft. 17. A pitcher for mixing a liquid solution, said pitcher comprising a container for containing liquid, a lid releasably securable on the container, and a mixing device disposed at least in part within the container, the mixing device comprising a shaft adapted for translation relative to the container, an agitating member connected to the shaft for conjoint translation therewith relative to the container to agitate the liquid in the container, the agitating member including a plurality of spaced apart blades with each of said blades being curved and angled with respect to the shaft, each of said blades having a length and being twisted along the length, and a stop disposed on the shaft, the stop being selectively movable along the shaft between the lid and the agitating member. 18. The pitcher as set forth in claim 17 wherein the agitating member is adapted for rotation within the container in response to translating movement of the shaft. 19. The pitcher as set forth in claim 18 wherein the shaft is adapted for rotation upon translation of the shaft, the agitating member being operatively connected to the shaft for conjoint rotation therewith. 20. The pitcher as set forth in claim 19 wherein the shaft has fins that spiral helically around the shaft. 21. The pitcher as set forth in claim 20 wherein the lid has an opening and a pair of key slots extending radially outward from opposite sides of the opening, the shaft being received through the opening such that the fins of the shaft are received in the respective key slots. 22. The pitcher as set forth in claim 17 wherein the agitating member further includes an annular support interconnecting each of the blades. 23. The pitcher as set forth in claim 17 wherein the agitating member connects to the shaft such that a passageway is formed between the agitating member and the shaft for allowing liquid to flow through that passageway during translational movement of the shaft. 24. The pitcher as set forth in claim 17 wherein the container comprises a spout having a purchase rib. 25. The pitcher as set forth in claim 6 wherein the lid has a recess therein, the grip being selectively moveable between an operative position and a stowed position wherein at least a portion of the grip is received within the recess.
