Abstract (en)
[origin: FR2760435A1] The invention concerns a double-walled tube (1) for storing and dispensing hazardous products, comprising an inner tube (10) with a skirt (13), a shoulder (12) and an inner neck (11) delimiting an inner orifice (14), a metal tube with a skirt (25), a shoulder (24) and an outer neck (21), the two tubes being mutually connected at their necks (11 and 21) by a joining piece (30) comprising a bottom (34) and at least an outer skirt (35) enclosing the two necks (11 and 21). The invention is characterised in that the joining piece (30) is provided with an inner skirt (31) with its outer wall having a globally truncated profile, such that, when the joining piece (30) is forcefully pushed down, said inner skirt (31) causes the median parts of the necks (11 and 21) to expand at their circumference, thus widening the ends of said necks.
