摘要
The assembly has an exterior emptying orifice (6) closed by a valve (7). The valve has a movable obturation element (8) whose head (10) is supported on a base forming part to ensure sealing, in a closed position. The orifice is fitted in a lower part of an annular total flow and base part (11). The part (11) is in the form of a thick and flat annular joint provided with a central opening (25) whose upper part has a conical recess (21) i.e. double ramp recess, which serves as a base to the head and permits total flow of a contained liquid product, without retaining zones.
