Abstract
A closure stopper for pharmaceutical applications has a sealing flange seating in a sealing manner on an end face of the container's closure mouth. The sealing flange has a lower sealing surface and a boundary plane contacting an area protruding farthest downwardly and extending perpendicularly to the closure stopper's center axis. An engagement portion extending below the sealing flange is formed with a smaller radial extent than the sealing flange. Preferably a handling portion extends above the sealing flange. A circumferential sealing projection also is formed on the engagement portion and protrudes by a radial dimension with respect to an axial portion of the engagement portion initially adjoining the sealing flange from underneath and having a portion-radius. The sealing projection, at least with respect to its base portion, vertically overlaps a set-back region formed on the sealing flange and set back with respect to the contact plane.
