A one-way valve for a container supplying a liquid under pressure when the container is compressed is designed to be inserted between an outlet of the container and the end of a supply nozzle connected to the container. The valve includes a hollow body inserted partially into the outlet of the container. A base of the hollow body, which is engaged by the end of the nozzle, is open, while the other base of the body has an essentially central hole through which the liquid passes. The hollow body accommodates internally an obturator member essentially including a shaped stopper connected, via elastically deformable lugs, to a support element. The support element has a longitudinal passage of a cross-sectional area greater than that of a cavity formed in the stopper. The lugs are designed to keep the stopper within the hole of the hollow body when the container is not compressed and to allow it to be moved out of the hole when the container is compressed in order to supply the liquid.
