A fitting to provide a pouring spout at a hole through a sheet material (e.g. cartonboard) container has a flange 10 which abuts the material 44 around the hole. A tubular portion 12 extends through the hole and tapers. A ring 36 is dimensioned to fit on this tapered section 16 but become stretched upon pushing it up the taper towards the flange 10. It then engages a step 24 in the tubular portion, which retains the ring 36 in a position tightly encircling the tubular portion. The sheet material 44 is gripped between the ring 36 and the flange 10.

La présente invention porte sur un raccord servant à monter un bec verseur sur un orifice ménagé dans un contenant fabriqué à l'aide d'un matériau en feuille (un panneau de carton par exemple) et muni d'une bride (10) qui affleure le matériau (44) autour de l'orifice. Un segment tubulaire (12) pénètre l'orifice et forme un cône. Un anneau (36) est dimensionné pour s'ajuster à cette partie conique (16) mais peut s'étirer si on le soulève en le poussant au-dessus de la partie conique, vers la bride (10). Il s'engrène alors dans un cran (24) du segment tubulaire, qui retient cet anneau (36) de telle manière qu'il enserre fermement le segment tubulaire. Le matériau en feuille (44) est coincé entre l'anneau (36) et la bride (10).
