The base portion comprises a floor and a sidewall connected to and extending from the floor to form a chamber for receiving at least a portion of the foodstuff during a blending operation. The chamber has an open end in fluid communication with the open end of the container portion when the container portion and the base portion are selectively coupled. The base further comprises one or more rotatable blades that are fully contained within the chamber formed by the floor and the sidewall and do not extend beyond a rim of the sidewall. ## Claims ### Claim 1 A blender jar assembly for blending foodstuff, the blender jar assembly comprising: a container portion having an open end for receiving the foodstuff to be blended and for dispensing the foodstuff after blending; and a base portion selectively coupleable to the container portion, the base portion comprising a floor and a sidewall connected to and extending from the floor to form a chamber for receiving at least a portion of the foodstuff during a blending operation, the chamber having an open end in fluid communication with the open end of the container portion when the container portion and the base portion are selectively coupled, the base portion further comprising one or more rotatable blades and one or more spires projecting from the rim of the sidewall, the one or more spires extending into the container portion when the container portion and the base portion are selectively coupled; wherein the one or more rotatable blades are fully contained within the chamber formed by the floor and the sidewall and do not extend beyond a rim of the sidewall. ### Claim 2 (depends on 1) The blender jar assembly of claim 1, wherein the sidewall comprises one or more protrusions to increase agitation of the foodstuff within the chamber. ### Claim 3 (depends on 2) The blender jar assembly of claim 2, wherein each of the one or more spires is aligned with a corresponding one of the one or more protrusions. ### Claim 4 (depends on 1) The blender jar assembly of claim 1, wherein the base portion comprises external threads and the container portion comprises corresponding internal threads such that the base portion and the container portion are selectively coupleable via the corresponding external and internal threads and such that a portion of the base portion is inserted into the container portion when the base portion and the container portion are selectively coupled. ### Claim 5 A blender for blending foodstuff, the blender comprising: a blender jar assembly; and a housing for selectively receiving the blender jar assembly; wherein the blender jar assembly comprises: a container portion having an open end for receiving the foodstuff to be blended and for dispensing the foodstuff after blending; and a base portion selectively coupleable to the container portion, the base portion comprising a floor and a sidewall connected to and extending from the floor to form a chamber for receiving at least a portion of the foodstuff during a blending operation, the sidewall further comprises one or more protrusions to increase agitation of the foodstuff within the chamber, the chamber having an open end in fluid communication with the open end of the container portion when the container portion and the base portion are selectively coupled, the base portion further comprising one or more rotatable blades; and wherein the one or more rotatable blades are fully contained within the chamber formed by the floor and the sidewall and do not extend beyond a rim of the sidewall. ### Claim 6 (depends on 5) The blender of claim 5, wherein the base portion comprises one or more spires projecting from the rim of the sidewall, the one or more spires extending into the container portion when the container portion and the base portion are selectively coupled. ### Claim 7 (depends on 6) The blender of claim 6, wherein each of the one or more spires is aligned with a corresponding one of the one or more protrusions. ### Claim 8 (depends on 5) The blender of claim 5, wherein the housing comprises a first portion enclosing a motor and a second portion for selectively receiving the blender jar assembly, the second portion defining an opening through which the blender jar assembly is selectively received; and wherein the blender further comprises a shield selectively coupled to the second portion via a substantially vertical pivot point, the pivot point enabling the shield to be selectively pivoted between a closed position closing off the opening in the second portion and an open position enabling the blender jar assembly to be inserted into or removed from the second portion. ### Claim 9 (depends on 8) The blender of claim 8, wherein the pivot point further comprises an overcenter cam mechanism that urges the shield toward the closed position when the shield is positioned between the closed position and a maximum displacement point of the overcenter cam and that urges the shield toward the open position when the shield is positioned between the open position and the maximum displacement point of the overcenter cam. ### Claim 10 (depends on 9) The blender of claim 9, wherein the shield moves upward as the shield is pivoted from the closed position to the maximum displacement point of the overcenter cam; wherein the shield moves downward as the shield is pivoted from the maximum displacement point of the overcenter cam to the open position; wherein the shield moves upward as the shield is pivoted from the open position to the maximum displacement point of the overcenter cam; and wherein the shield moves downward as the shield is pivoted from the maximum displacement point of the overcenter cam to the closed position. ### Claim 11 (depends on 9) The blender of claim 9, wherein the overcenter cam comprises a top cam portion, a cooperating bottom cam portion, and a spring that urges the top cam portion and the bottom cam portion toward each other. ### Claim 12 (depends on 11) The blender of claim 11, wherein the shield is selectively coupled to the second portion via the top cam portion such that pivoting the shield causes the top cam portion to correspondingly rotate and such that rotating the top cam portion causes the shield to correspondingly pivot. ### Claim 13 (depends on 12) The blender of claim 12, wherein the shield comprises a pivot post selectively insertable into a corresponding cavity in the top cam portion. ### Claim 14 (depends on 13) The blender of claim 13, wherein the shield pivot post and the cavity of the top cam portion each comprise cooperating engaging surfaces. ### Claim 15 (depends on 5) The blender of claim 5, wherein the base portion comprises external threads and the container portion comprises corresponding internal threads such that the base portion and the container portion are selectively coupleable via the corresponding external and internal threads and such that a portion of the base portion is inserted into the container portion when the base portion and the container portion are selectively coupled. ### Claim 16 A blender jar assembly for blending foodstuff, the blender jar assembly comprising: a container portion having an open end for receiving the foodstuff to be blended and for dispensing the foodstuff after blending; and a base portion selectively coupleable to the container portion, the base portion comprising a floor and a sidewall connected to and extending from the floor to form a chamber for receiving at least a portion of the foodstuff during a blending operation, the base portion further comprises one or more spires projecting from the rim of the sidewall, the one or more spires extending into the container portion when the container portion and the base portion are selectively coupled, the sidewall further comprises one or more protrusions to increase agitation of the foodstuff with in the chamber, each of the one or more spires being aligned with a corresponding one of the one or more protrusions, the chamber having an open end in fluid communication with the open end of the container portion when the container portion and the base portion are selectively coupled, the base further comprising one or more rotatable blades; wherein the base portion comprises external threads and the container portion comprises corresponding internal threads such that the base portion and the container portion are selectively coupleable via the corresponding external and internal threads and such that a portion of the base portion is inserted into the container portion when the base portion and the container portion are selectively coupled. ### Claim 17 (depends on 16) The blender jar assembly of claim 16, wherein the one or more rotatable blades are fully contained within the chamber formed by the floor and the sidewall and do not extend beyond a rim of the sidewall.
