Definitions

• the present invention relates to a closure device for a container neck.
• the invention relates generally to plugs, typically made of plastic, which comprise a tubular skirt, designed to surround the neck of a container to be plugged and that their inner face is fixed removably to the face external of this neck: this attachment is for example made by screwing, as in FR 2 987 607, the plugs then being generally called screw caps, or this removable attachment can be made by jamming, as in FR 2 908 746, the plugs are then generally called snap caps or "snap".
• the skirt is surmounted by a closing wall from the periphery of which the skirt extends axially: this closure wall extends across the container neck to close it when the skirt is fixed on the neck.
• a lip extending from the closure wall is arranged inside the skirt: when the skirt is attached to the neck, the outer face of this lip, that is to say its face turned radially away from the central axis of the skirt, rests tightly against an inner face of the neck so as to seal the closure of the neck.
• This sealing lip has its outer face which is generally bulged to ensure the most tight contact possible with the neck, the lip then being typically described as "olive lip”.
• US 5,458,252 discloses a plug having a lip of this type, inside which is arranged a deformable membrane.
• This membrane includes a central portion and a peripheral portion connecting the central portion to the lip.
• the plug of US 5 458 252 finds particular application in the field of packaging for medical use: the membrane is designed to deform during an increase in pressure inside a container closed by the cap. More precisely, during such an increase in pressure, the central and peripheral portions of the membrane do not deform together, but successively: in a first phase, only the central portion deforms, by articulation of a flexible hinge provided for in FIG.
