Abstract
The device comprises a distributing element (36) fastened on to the container (34) and provided with a membrane part (39) connected to the lower end of a distributing tubular part (38), which can assume, by means of the snap bending of the membrane (39), a more inner rest position and a more outer distributing position. A sealing element (40) has a tubular part (42) suitable to be inserted inside the tubular part (38) of the distributing element (36) and protruding beyond it. On the protruding region an annular projection (44) is provided, which, during the axial motion of the sealing element (40), which can be caused either by unscrewing or by pulling out, engages and drags the tubular part (38) of the distributing element (36) snapwise to the distributing position. The sealing element (40) is then disengaged from the distributing element (36). The engagement in correspondence of the lower end of the tubular part (38), below the zone in which the membrane is connected, allows a stronger engagement for extraction purposes and a longer stroke of the distributing element (36) with a higher stability of the positions of it.
