A food mixing machine (20) has an agitator (25) to mix food in a cup (C). A cup holder (31) is provided with a flexible boot (32) which receives the cup (C). The cup holder (31) is moveable through an opening (90) in the machine (20) and carries a gripping assembly (33) and an actuator assembly (34). The actuator assembly (34) is moveable relative to the gripping assembly (33) and is biased by springs (35) to maintain fingers (56) of the gripping assembly (33) in engagement with the cup (C). When it is desired to release the cup (C), a release assembly (80) overcomes the bias of the springs (35). As the cup holder (31) moves through the opening (90), the area between the cup holder (31) and the opening (90) is sealed by a seal assembly (91) so that food materials cannot go through the opening (90).Un mixeur daliments (20) comprend un agitateur (25) servant à mélanger des aliments dans un bol (C). Un porte-bol (31) doté dun socle souple (32) reçoit le bol (C). Le porte-bol (33) être introduit dans une ouverture (90) de lappareil (20) et comporte un ensemble de préhension (33) et un ensemble actionneur (34). Lensemble actionneur (34) peut se déplacer par rapport à lensemble de préhension (33) et se trouve sous charge de ressorts, ce qui maintient ses doigts (56) engagés dans le bol. Au moment de libérer le bol (C), lactionneur (80) se libère de la force des ressorts (35). Lorsque le port-bol (31) traverse louverture (90), la zone comprise entre lui et louverture (90) est obturée par un ensemble obturateur (91) qui empêche des parties daliments de passer par ladite ouverture (90).
