Abstract: The container has an end wall portion (12) provided with an access opening (A) in which is affixed a nozzle (B) in the form of a metallic tubular insert (20) comprising: a mounting portion (21) fitted in the access opening (A); a nozzle portion (22); an external peripheral flange (23), having an annular face (23a) in which are adapted annular sealing means (30); and a nut (40) adapted around the mounting portion (21) and pressing the end wall portion (12) against the annular sealing means (30) of the annular face (23a) of the flange (23). The end wall portion (12) may be preformed in a single piece with an annular wall portion or fixed to the latter, and provided, in both constructions, with a median opening (13,51) which defines the access opening (A) of the container.

Abstract: A plastic container for pressurized fluids, presenting a hollow body (10) in plastic material and comprising at least one annular mounting portion (11) molded around a tubular metallic insert (20) defining the nozzle for access to the inside of the container. The tubular metallic insert (20) carries a connecting ring (40) axially compressing an annular sealing means (30) against an annular seat (26) of the insert and to which is subsequently fused the body (10) of the container through the annular mounting portion of the latter.
