ABSTRACT:
The wide-necked barrel of a synthetic resin can be sealed by a lid exhibiting a bottom entering into the barrel neck by way of an inner rim, and an outer rim extending over the barrel neck and having a radial lid flange. The lid is sealed by a sealing ring inserted into the annular groove between the inner rim and the outer rim of the lid. The lid flange has on the underside alternatingly tongue-like extensions and recesses arranged with a specific pitch over the circumference of the lid. Annular flange segments integrally molded to the barrel neck engage into the flange recesses and complete the partial cross-sectional profile of the lid flange, formed in the zone of the recesses, to the full cross-sectional profile of the lid flange in the zone of the extensions. The clamping ring encompassing the lid flange and the annular flange segments is secured by means of clamping ridges integrally molded to the lid extensions and extending in the circumferential direction.
