Pressure-cooking utensil having a dual-purpose locking/unlocking control member

A utensil (1) for cooking food under pressure, which utensil comprises a vessel (2), a lid (3), locking/unlocking means (4) for locking/unlocking the lid (3) relative to the vessel (2), and a control member (6) for controlling locking/unlocking of the lid (3) relative to the vessel (2), said utensil being characterized in that said control member (6) is mounted to pivot on the lid (3) about a pivot axis (Y-Y′) between firstly a deployed position corresponding to the lid (3) being unlocked and in which said control member (6) is designed to be taken hold of manually in order to enable the lid (3) to be handled, and secondly a retracted position corresponding to the lid (3) being locked and in which said control member (6) is designed to be more difficult to take hold of manually than it is in the deployed position, said locking/unlocking means (4) having jaws mounted to move in radial translation along a translation axis parallel to said pivot axis (Y-Y′), wherein the (4A, 4B) are mounted, via corresponding drive arms (4C, 4D), to move between firstly a locking position in which each jaw (4A, 4B) clamps the lid (3) and the rolled top rim of the vessel (2) and secondly an unlocking position obtained by moving the jaws (4A, 4B) outwards from their locking position and in which the jaws (4A, 4B) are no longer in engagement with the rolled rim of the vessel (2), thereby enabling the lid (3) to be released from the vessel (2) freely by the user, and wherein each drive arm (4C, 4D) extends between an inner end designed to co-operate with the locking/unlocking control member (6), and an outer end that carries the corresponding jaw (4A, 4B).
