Claim 22:
23. Housing for a pressurized container, comprising:
a bottom comprising:
an opening intended to be closed by a stopper;
sealing means to ensure sealing between the stopper and the housing when the housing is provided with the stopper; and

retaining means to retain, when the container is pressurized, the stopper closing the opening,
wherein the retaining means are distinct from the stopper and are in an inactive initial form and must, in order to fulfill their function, be activated after the opening has been closed with a stopper,
wherein the retaining means comprise a deformation zone made on the bottom in an extension of the opening, on a face of the bottom oriented toward an outside of the housing, the deformation zone being designed to be deformed, after introduction of the stopper in the opening, to form an abutment surface for the stopper to prevent the stopper from moving toward the outside of the housing.
