Abstract: A container may include a wall and an outlet valve, where the outlet valve includes: a membrane that is elastically deformable under the effect of positive pressure of a substance relative to the outside, an outer surface of the membrane being in contact with an external environment, in the area of a slit formed in a zone for removing the substance, the slit being suitable for allowing the discharge of a flow of the substance caused by the positive pressure; a wall configured to be, in the absence of positive pressure of the substance, in contact with an inner surface of the membrane along a contact line arranged on the periphery of the slit, and configured to allow the inner surface of the membrane to move away from at least part of the wall in the event of positive pressure of the substance.

Abstract: A handle assembly, including at least: a first handle including at least one recess and a square spindle configured to be received at least partially within the recess of the first handle, in an initial configuration, the first handle is configured to slide freely along the longitudinal axis of the square spindle over a given distance, the first handle is configured to pass from the initial position to a securing configuration in which the first handle is immobilized in translation and in at least one direction of rotation with respect to the square spindle, by at least one displacement in rotation of the first handle about the longitudinal axis of the square spindle through an angle strictly less than 360°.
