Abstract

A stirring stick for manipulating foodstuff in a blender comprises an elongate plunger having first and second ends. The plunger has a cavity extending between the first and second ends. At least a portion of the plunger is generally trough-shaped, and the cavity is open at least at the second end. A handle is attached to the first end of the plunger. A user may move the stirring stick in one or more directions when the stirring stick is positioned in the blender.

Claims (22)

1. A stirring stick for manipulating foodstuff in combination with a blender, the combination comprising:

a blender base containing a motor;

a blender jar releasably attached to the base, the blender jar being open at a top end and closed at a bottom end;

a blade set drivingly connected to the motor, the blade set extending into the blender jar proximate the bottom end;

an elongate plunger having first and second ends, the plunger having a single trough-shaped cavity extending between the first and second ends, the cavity having first and second side edges, the cavity being open between the first and second side edges to form a tapered opening extending from the first end to the second end;

a scoop attached to the second end of the plunger, the scoop having a plunger tip forming a continuous, substantially planar, straight scraping edge separate from and extending beyond the first and second side edges;

a handle attached to the first end of the plunger, the handle including a generally disc-shaped collar connected to the first end of the plunger, a constant diameter cylindrically shaped portion connected to the collar, and a top grippable portion having a semi-spherically shaped dome and a substantially planar base, the top portion being connected to the cylindrical portion at the base.

2. The stirring stick of claim 1 , wherein the collar has an outer diameter which is larger than a maximum outer diameter of the plunger.

3. The stirring stick of claim 1 , wherein the collar has an outer diameter which is larger than an outer diameter of the cylindrically shaped portion.

4. The stirring stick of claim 1 , wherein the collar has an outer diameter which is larger than a maximum outer diameter of the semi-spherically shaped dome.

5. A blender for blending foodstuff comprising:

a base containing a motor;

a blender jar releasably attached to the base, the blender jar being open at a top end and closed at a bottom end;

a blade set drivingly connected to the motor, the blade set extending into the blender jar proximate the bottom end;

a lid covering a substantial portion of the top end of the blender jar, the lid having an opening extending therethrough; and

a stirring stick capable of being installed through the opening in the lid and into the blender jar from the top end, wherein the stirring stick comprises:

an elongate plunger having first and second ends, the plunger having a single trough-shaped cavity extending between the first and second ends, the cavity having first and second side edges, the cavity being open between the first and second side edges to form a tapered opening extending from the first end to the second end;

a scoop attached to the second end of the plunger, the scoop having a plunger tip forming a continuous, substantially planar, straight scraping edge separate from and extending beyond the first and second side edges;

a handle attached to the first end of the plunger, the handle including a generally frustoconically-shaped collar connected to the first end of the plunger, and a top grippable portion having a plurality of external ribs, the top portion being connected to the collar.

6. The blender of claim 5 , wherein the collar includes a substantially planar base, and the top portion is connected to the base.

7. The blender of claim 5 , wherein the collar has a maximum outer diameter which is larger than a maximum outer diameter of the plunger.

8. The blender of claim 5 , wherein the collar has a maximum outer diameter which is larger than a maximum outer diameter of the top portion.
