1. Packaging comprising a receptable having an opening provided with a rim of which the edge comprises an upper annular bearing surface (11) which receives the sealing joint (7) moulded of thermoplastic material of a cover having at its periphery an annular part (6/8) having a surface to which the joint adheres, the border of the cover comprising a ring (9) folded to double thickness in the direction of said joint, so that its edge is embedded in the thickness of the latter, characterised in that the cover is a lid of which the peripheral annular part (6/8) is substantially planar, whereas the annular bearing surface (11) of the receptacle receiving the joint is provided, towards the internal periphery of the rim, with at least one sealing flange (13) in relief relative to the remainder of the rim surface and has at its exterior periphery a flange or raised edge (12) projecting therefrom, the border (8) being housed behind the exterior flange (12). L'invention concerne un dispositif de bouchage associant à des récipients munis d'une bague dont la portée supérieure (11) possède un rebord extérieur (12) de protection et un jonc d'étanchéité intérieur (13) un opercule qui comprend à sa périphérie une partie annulaire (6, 8) à une face de laquelle adhère un joint d'étanchéité (7) en une matière thermoplastique, ladite partie annulaire possédant un bord (8) comportant une collerette (9) repliée à épaisseur double en direction dudit joint de façon telle que la tranche (10) de cette collerette soit protégée par ledit joint. Un tel dispositif permet un bouchage économique de récipients en verre de grandes dimensions.
