2. Tap for the distribution of liquids, essentially constituted by a body ( 1 ) for mounting in the bung of a receptacle and for distribution of the liquid, by a valve or membrane ( 2 ) for sealed closure of an opening ( 3 ) for distribution of the liquid, provided with a control member ( 4 ) and made in the form of a single piece element with said control member ( 4 ) and with a means ( 6 ) for sealed application of said valve ( 2 ) or member sealingly closing the opening ( 3 ) for dispensing the liquid on its seat, said valve being disposed in the portion of the body ( 1 ) opposite that for mounting in the bung, and by a means ( 5 ) for actuating said control member ( 4 ), characterized in that the means ( 6 ) for sealed application of the valve ( 2 ) or member for sealed closure of the opening ( 3 ) for distribution of the liquid on its seat, is constituted by a resiliently deformable element forming a spring and connected on the one hand to the valve or membrane ( 2 ) for sealed closure of the opening ( 3 ) for distribution of the liquid, and to the control member ( 4 ) by means of a common guide element ( 7 ) and, on the other hand, to a securement flange ( 8 ) co-acting with securement lugs for the centering ( 9 ) of the body ( 1 ) wherein the means ( 5 ) for actuating the control member ( 4 ) is constituted by a pushbutton in the form of a resiliently deformable membrane provided on the body ( 1 ) of the valve and connected to the latter in a sealed manner.

3. Tap for the distribution of liquids, essentially constituted by a body ( 1 ) for mounting in the bung of a receptacle and for distribution of the liquid, by a valve or membrane ( 2 ) for sealed closure of an opening ( 3 ) for distribution of the liquid, provided with a control member ( 4 ) and made in the form of a single piece element with said control member ( 4 ) and with a means ( 6 ) for sealed application of said valve ( 2 ) or member sealingly closing the opening ( 3 ) for dispensing the liquid on its seat, said valve being disposed in the portion of the body ( 1 ) opposite that for mounting in the bung, and by a means ( 5 ) for actuating said control member ( 4 ), characterized in that the means ( 6 ) for sealed application of the valve ( 2 ) or member for sealed closure of the opening ( 3 ) for distribution of the liquid on its seat, is constituted by a resiliently deformable element forming a spring and connected on the one hand to the valve or membrane ( 2 ) for sealed closure of the opening ( 3 ) for distribution of the liquid, and to the control member ( 4 ) by means of a common guide element ( 7 ) and, on the other hand, to a securement flange ( 8 ) co-acting with securement lugs for the centering ( 9 ) of the body ( 1 ) wherein the resiliently deformable element ( 6 ) forming a spring and constituting the means ( 6 ) for sealed application of the valve ( 2 ) or membrane for sealed closing of the opening ( 3 ) for dispensing the liquid on its seat is constituted in the form of a pair of resilient blades each connected by one end to the common guide element ( 7 ) on the side opposite the connection portion between the control member ( 4 ) and the valve or membrane ( 2 ), and at the other end of the securement member ( 8 ) co-acting with securement and centering lugs ( 9 ) on the body ( 1 ), said resilient blades forming a loop between their two ends.

4. Tap for the distribution of liquids, essentially constituted by a body ( 1 ) for mounting in the bung of a receptacle and for distribution of the liquid, by a valve or membrane ( 2 ) for sealed closure of an opening ( 3 ) for distribution of the liquid, provided with a control member ( 4 ) and made in the form of a single piece element with said control member ( 4 ) and with a means ( 6 ) for sealed application of said valve ( 2 ) or member sealingly closing the opening ( 3 ) for dispensing the liquid on its seat, said valve being disposed in the portion of the body ( 1 ) opposite that for mounting in the bung, and by a means ( 5 ) for actuating said control member ( 4 ), characterized in that the means ( 6 ) for sealed application of the valve ( 2 ), or member for sealed closure of the opening ( 3 ) for distribution of the liquid on its seat, is constituted by a resiliently deformable element forming a spring and connected on the one hand to the valve or membrane ( 2 ) for sealed closure of the opening ( 3 ) for distribution of the liquid, and to the control member ( 4 ) by means of a common guide element ( 7 ) and, on the other hand, to a securement flange ( 8 ) co-acting with securement lugs for the centering ( 9 ) of the body ( 1 ) wherein the securement flange ( 8 ), connected to the resiliently deformable member ( 6 ) forming a spring and constituting the means ( 6 ) for sealed application of the valve ( 2 ) or closure membrane sealed with the opening ( 3 ) for dispensing the liquid on its seat, and provided with openings ( 9 ′) of a shape corresponding to tat of the securement and centering lugs ( 9 ) and is secured with these latter by riveting or welding alter mounting.
