Abstract

A drink maker for processing foodstuff and dispensing the processed foodstuff therefrom. A base encloses a motor and a jar including a first recirculation surface is removably mountable to the base. A processing cup including a second recirculation surface is removably mountable to the jar and the jar and processing cup comprise a container in an assembled configuration. A recirculation chamber is defined by the first and second recirculation surfaces. The base includes an arcuate-shaped mounting wall extending from its top surface and the jar includes a skirt having a first wall and a second wall positioned radially outwardly from the first wall. The first and second walls define a mounting gap and the mounting wall is positioned in the mounting gap in the assembled configuration.

5. The drink maker of claim 1 further comprising:

a generally cylindrical cutting blade mounted to an inner surface of the peripheral wall of the processing cup, the cutting blade including a plurality of grating slots.

6. The drink maker of claim 1 further comprising:

a dispensing spout mounted to the jar and being in fluid communication with the recirculation chamber, the dispensing spout movable between an open position to dispense foodstuff and a closed position to block foodstuff from flowing out of the container.

7. The drink maker of claim 1 wherein the jar includes a lower skirt comprised of a first wall and a second wall, the second wall positioned radially outwardly from the first wall, the first and second walls defining a mounting gap therebetween.

8. The drink maker of claim 7 wherein the base includes an arcuate-shaped mounting wall extending from a top surface, the mounting wall positioned within the mounting gap in the assembled configuration.

9. The drink maker of claim 8 wherein the mounting wall includes an indent and one of the first and second walls includes a rib extending radially into the mounting gap, the rib positioned within the indent in the assembled configuration.

10. The drink maker of claim 1 wherein the peripheral wall includes a hole therein, the base surface including a groove that pitches downwardly toward a bottom apex of the hole.

11. The drink maker of claim 1 wherein the jar includes a sealing edge and the processing cup includes a radially outwardly extending platform, the sealing edge engaging the platform to seal the container.

12. The drink maker of claim 11 further comprising:

a gasket positioned between the sealing edge and the platform.

13. The drink maker of claim 11 wherein the jar includes a lower skirt comprised of a first wall and a second wall, the second wall positioned radially outwardly relative to the first wall, the sealing edge comprised of a terminal end of the first wall.

14. The drink maker of claim 1 further comprising:

a lid removably mountable to a mouth of the jar, the lid including a movable hatch.

15. The drink maker of claim 1 further comprising:

a dispensing spout mounted to the jar, the base including a cup indentation on a side surface, the dispensing spout positioned proximate the cup indentation in the assembled configuration.

16. The drink maker of claim 1 further comprising:

an impeller removably and rotatably mounted to the processing cup, the impeller having a generally disc-shape including a first surface and a second surface.

17. The drink maker of claim 16 wherein the second surface faces the base surface in the assembled configuration, the second surface, base surface and an inner surface of the processing cup further defining a receiving chamber.

18. The drink maker of claim 17 wherein the impeller includes at least one grinding tooth extending generally perpendicularly from the first surface and at least one urging tooth extending generally perpendicularly from the second surface, the at least one urging tooth being integrally formed from a portion of the impeller.

19. The drink maker of claim 18 wherein the at least one grinding tooth comprises a first grinding tooth and a second grinding tooth, the first and second grinding teeth positioned proximate a periphery of the impeller and including driving faces that are oriented generally perpendicularly to a rotation direction of the impeller.

20. The drink maker of claim 18 wherein the at least one urging tooth comprises a first urging tooth and a second urging tooth extending from the impeller toward the base surface in the assembled configuration, the first and second urging teeth positioned behind the first and second grinding teeth relative to a direction of rotation of the impeller.

21. The drink maker of claim 1 wherein the jar includes a funnel-shaped recirculation rib extending radially, inwardly from an inner surface of the jar and an arcuate-shaped channel extending generally between a mouth and a base end of the jar, wherein the channel extends radially outwardly relative to remaining surfaces of the jar.

22. The drink maker of claim 21 wherein the recirculation rib includes a root end and a distal end, a first diameter defined by the distal end, the top edge of the peripheral wall defining a second diameter.

23. The drink maker of claim 22 wherein the first diameter is approximately seventy-five to ninety-five percent of the second diameter.

24. The drink maker of claim 22 wherein the first diameter is less than the second diameter and the distal end of the recirculation rib is positioned radially inwardly from the top edge of the peripheral wall in an assembled configuration relative to a longitudinal axis of the drink maker to inhibit the formation of a vortex in the jar during operation.

25. The drink maker of claim 24 wherein the distal end and the top edge are positioned on a generally horizontal recirculation plane in the assembled configuration.
