The container comprises a peripheral side wall (10), whose upper peripheral edge (10c) defines a retention hook (11) with a profile in the form of an inverted U, having an inner side leg (11a), an arched base leg (11b) and an outer lateral leg (11c). An upper end wall (20) of the container comprises a median panel (21) and a peripheral upper skirt (22) having an end edge (22c) defining a closure hook (23) with a profile in the form of an inverted U, having an inner side portion (23a), an arched base portion (23b), and an outer side portion (23c) which incorporates an upwardly projecting end flange (23d). The closure hook (23) is fitted onto the retention hook (11) and radially inwardly deformed, compressing an elastic sealing element (40) between the two hooks and maintaining the end flange (23d) projecting upwardly to the interior of the retention hook (11). |
