A closure cap for closing a container under vacuum, comprising a circular closing disc having a flanged, edge, a sealing compound provided therein and a sealing ring of synthetic material, having an L-shaped cross-section. The radially inwardly directed edge of the sealing ring forms an abutment for the circular closing disc. A substantially cylindrical skirt encloses the flanged edge of the closing disc. Inwardly directed projections, adapted to engage underneath the thickened edge of a container to be sealed are provided on the inside of the skirt. The sealing ring is fitted with a guaranty construction, comprising a tiltable tear-off tab (2), disposed within the standard height (h) of the skirt (4) of the sealing ring (1). The tear-off tab is connected to the skirt by means of two tear lines, extending in axial direction of the skirt. |
