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 d
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.

Sealing and distributing device for containers of fluids, comprising a distributing element (24,36) provided with a part (25,26;37) of substantially annular shape, suitable to be fixed to the container (11,34) in correspondence of a distribution orifice (35) of the same, and with a substantially tub
Sealing and distributing device for containers of fluids, comprising a distributing element (24,36) provided with a part (25,26;37) of substantially annular shape, suitable to be fixed to the container (11,34) in correspondence of a distribution orifice (35) of the same, and with a substantially tubular part (28,38) coaxial with the annular part (25,26;37) and axially movable relatively to it, the two parts (25,26;37 and respectively 28,38) being connected to each other by a membrane part (27,39) and comprising a sealing element (12,40) suitable to be connected to the said container (11,34) to the purpose of sealing it and provided with an axial cylindrical projection (20,42) having engagement means (22,44) with the said tubular part (28,38) for causing the axial shifting of it from a rest position substantially inside the container (11,34) to a distributing position extending outside from the container (11,34) and vice-versa, the sealing element (12,40) being removable from said distributing element (24,36) in the distributing position, characterized in that the projection (20,42) of the sealing element (12,40) is longer than said tubular part (28,38) and has the engagement means (22,44) with said tubular part (28,38) on its region protruding beyond the end of said tubular part (28,38), the projection (20,42) of the sealing element (12,40) being removable through the tubular part (28,38) of said distributing element (24,36) after the axial shifting of the said tubular part (28,38) to the distributing position and after the liberation of the said engagement means (22,44) by the cooperable means of the said tubular part (28,38).
