Abstract: The container (1) includes a body (2), a kinkable/unkinkable flexible sleeve (3) and an apertured maneuvering member (4) for maneuvering the sleeve (3). According to the invention: the body (2) and the member (4) have a globally square or rectangular shape in cross-section, giving the container (1) the appearance of a box; the member (4) is axially movable relative to the body (2), between a position in which it is freed from the wall of the body (2) and can therefore be pivoted relative to the latter, and a position in which it is engaged with the body (2); and the wall of the body (2) outwardly includes at least one part (5) made from a material having a high friction coefficient, and/or the apertured maneuvering member (4) includes, on its inner face, at least one part made from a material having a high friction coefficient.

Abstract: The invention relates to a container (1) which includes a body (2) forming an opening, a mobile ring (4) capable of pivoting relative to said body (2), and a seal (3) made of a flexible, resilient material, connected to said body (2) as well as to said ring (4), capable of being twisted by pivoting the ring (4). According to the invention, said body (2) includes a circular peripheral wall (10) ending in a free edge that defines said opening, and said ring (4) is intended for being positioned around said wall (10); and one of said peripheral wall (10) or said ring (4) includes a series of grooves (11 and 15) and the other one of said ring (4) or said peripheral wall (10) includes a lug, the movement of said lug in said series of grooves enabling guided axial movement of the ring (4) relative to the wall (10) when the seal (3) starts to twist.
