Abstract

The invention relates to a closure, comprising: - a container with a sealing ring (8) shrunk by heating and gripping beneath the locking collar; a number of connections (9) in spread positions between the sealing ring and an inside lower edge zone of the screw cap; a protective edge (11) extending over at least a portion of the connections (9). The invention proposes a closure of the stated type which displays the feature that each connection (9) comprises: a bridge portion (12) moulded onto the sealing ring (8) on the top side and having radial and axial dimensions in the same order of magnitude as those of the sealing ring (8); and a breaking portion (13) extending between that bridge portion (12) and the inside lower edge zone (10) of the screw cap (6) and having a smaller cross-sectional surface area than the bridge portion (12), which breaking portions (13) are covered off by the protective edge (11), whereby, prior to the shrinking process and after the screwing of the screw cap (6) into position on the container the sealing ring (8) is situated on an axial position relative to the locking collar such that during shrinking of the sealing ring (8) under the influence of localised temporary heat supply the shrinking forces thereby occurring cause a tensile stress in the connections (9) such that the breaking portions (13) undergo a stretching with associated cross-sectional surface area reduction.
