Abstract
A disposable agitator (12, 12A) for a food mixer (10) includes an elongate hollow sleeve stem (16, 24) which fits over and rotates with an elongate rotatable shaft (11, 11A) of the mixer (10). An agitator blade (17, 25) configured in the shape of a bowl of a spoon is positioned at the bottom of the stem (16, 24). In one embodiment a detent (18) in the stem (16) engages a recess (14) in the shaft (11) while in another embodiment a barb (29) engages a flange (23) on the shaft to longitudinally position the agitator (12) on the shaft (11). The agitator is used by sliding the hollow stem (16, 24) upwardly over the shaft (11, 11A) to, in one embodiment, to cause the detent (18) to engage the recess (14), and in the other embodiment to cause the barb (29) to engage the flange (23). After mixing the food product, the user is induced to remove the agitator (12, 12A), because the blade (17, 25) is configured like the bowl of a spoon, by sliding the stem (16, 24) downwardly away from the shaft (11, 11A).
