In order to manufacture a closure having an improved seal and lower degree of wear at more reasonable cost, a closure is proposed, the closure comprising an upper part (5), a lower part (4) and a conveying sleeve (6) with a sealing pin (65). On the lower part (4) there are two concentric, upwardly directed annular walls (48) which interact under prestress with two corresponding, concentrically downwardly directed annular walls (500) on the upper part (5), which annular walls are directed downwards. The lower part (4) and the conveying sleeve (6) can be manufactured integrally via predetermined breaking point bridges (600), thus making it possible to obtain a cost-saving method of assembly.

L'invention concerne une fermeture avec un joint d'étanchéité amélioré et une plus faible usure, de fabrication plus économique, constituée d'une partie supérieure (5), d'une partie inférieure (4) et d'une douille d'alimentation (6) avec une goupille d'étanchéité (65). Sur la partie inférieure (4) sont disposées deux parois annulaires (48) concentriques, orientées vers le haut, qui coopèrent avec précontrainte avec deux parois annulaires (500) sur la partie supérieure (5), correspondantes et orientées concentriquement vers le bas. La partie inférieure (4) et la douille d'alimentation (6) peuvent être fabriquées d'une seule pièce par le biais de ponts (600) de zones destinées à la rupture, de sorte que l'on peut obtenir un procédé de montage économique.
