Abstract

La présente invention porte sur un appareil de manipulation d'aliments (1) comprenant un récipient (2), une porte (3) pour permettre l'accès au récipient (2), et au moins un dispositif de verrouillage (4) pour sceller la porte (3) contre le récipient (2). Le dispositif de verrouillage (4) comprend une broche coulissante fixe (5) et une unité rotative (6) agencée pour recevoir la broche coulissante (5), l'unité rotative (6) ayant une partie de base (7) et une poignée (8) destinée à faire tourner la partie de base (7) par rapport à la broche coulissante (5). La partie de base (7) comprend une surface d'engagement (9) pour un engagement coulissant avec la broche coulissante (5), et la surface d'engagement (9) est inclinée de telle sorte qu'une force appliquée sur la broche coulissante (5) par la surface d'engagement (9) augmente progressivement lorsque la partie de base (7) est tournée par rapport à la broche coulissante (5), pour ainsi presser et sceller la porte (3) contre le récipient (2).
