The invention relates to a recipient for food pressure-cooking which comprises a cooking vessel (2), a lid (3), a locking unit (5) and supporting means arranged between said lid (3) and locking unit (5) and is characterised in that the lid (3) and the vessel (2) are constructed such that the lid (3) penetrates inside the vessel (2) in such a way that an engageable lid is formed, said supporting means divides the lid (3) into one or several fixed angular sectors (3F) and into one or several free angular sectors and said supporting means and the lid (3) are sized in such a way that the controlled deformation of the free sector(s) of the lid by a pressure inside the vessel is produced. The invention can be used for recipients for food pressure-cooking.
