A pot (100) comprising a body (10) presenting a cavity with an opening (11b), and a lid (20) that is movable relative to the body (10). The body (10) has an engagement element (14e) and the lid (20) has a closure tab (70) movable between an engaged position in which, when the lid (20) is in a shut position in which the lid shuts the opening, the closure tab (70) co-operates with the engagement element (14e) and thus holds the lid (20) in the shut position, and a disengaged position in which the closure tab (70) does not co-operate with the engagement element (14e). The pot has a blocking tongue (42) movable between a locked position in which it blocks the closure tab (70) in the engaged position, and an unlocked position in which the closure tab (70) is movable between the engaged position and the disengaged position.
