Container, in particular for food use, comprising: - a container body forming an opening, - a moving ring capable of pivoting relative to the container body, between a position freeing the opening and a position closing off the opening, and - a seal made from a flexible resilient material, connected to said body on the one hand and to said ring on the other hand, able to be twisted by pivoting the ring relative to the body between said released and closed off positions, the deformation of the seal occurring between a non-twisted state, in which the seal frees the opening of the container, and a twisted state, in which said seal closes off that opening; said body comprises a circular peripheral wall ending with a free edge that delimits said opening, and said ring is designed to be engaged around that wall; - one from among said peripheral wall and said ring comprises: - an oblique groove, a first end of which is situated at a first axial distance from said opening and a second end of which is situated at a second axial distance from said opening; - a circumferential groove, one end of which communicates with said second end of said oblique groove; and - a plurality of notches formed along said circumferential groove, laterally relative to said groove and communicating therewith; - the other from among said peripheral wall and said ring comprises a lug capable of being engaged and sliding in said oblique groove and in said circumferential groove, and capable of partially engaging in one or the other of said notches of said plurality of notches, said oblique groove being positioned such that the movement of said lug therein produces an axial movement of the ring in the direction bringing the ring and said opening axially closer together during a first part of the movement of the ring from said released position to said closing off position, and, conversely, such that said movement produces an axial movement of the ring in the axial separation direction of the ring and said opening during a second part of the movement of the ring from said closing off position to said released position, at least a first of said notches being angularly positioned so as to receive said lug when the seal is in a partial twisted state, and a second of said notches being positioned angularly so as to receive said lug when the seal is in a complete twisted state. - a container body forming an opening, - a moving ring capable of pivoting relative to the container body, between a position freeing the opening and a position closing off the opening, and - a seal made from a flexible resilient material, connected to said body on the one hand and to said ring on the other hand, able to be twisted by pivoting the ring relative to the body between said released and closed off positions, the deformation of the seal occurring between a non-twisted state, in which the seal frees the opening of the container, and a twisted state, in which said seal closes off that opening; - one from among said peripheral wall and said ring comprises: - an oblique groove, a first end of which is situated at a first axial distance from said opening and a second end of which is situated at a second axial distance from said opening; - a circumferential groove, one end of which communicates with said second end of said oblique groove; and - a plurality of notches formed along said circumferential groove, laterally relative to said groove and communicating therewith; - an oblique groove, a first end of which is situated at a first axial distance from said opening and a second end of which is situated at a second axial distance from said opening; - a circumferential groove, one end of which communicates with said second end of said oblique groove; and - a plurality of notches formed along said circumferential groove, laterally relative to said groove and communicating therewith; - the other from among said peripheral wall and said ring comprises a lug capable of being engaged and sliding in said oblique groove and in said circumferential groove, and capable of partially engaging in one or the other of said notches of said plurality of notches,
