ABSTRACT:
Improvements in service valve heads which may be connected to soft drink bottles or the like, wherein a valve body is obtained, a liquid circulation channel being provided between the spout and the fishing tube, said channel having a check valve. The rod of said valve is actuated by a command means whose the articulated arm is foldable over the valve body, having folding stops and having a strap provided with a retainer. Folding stops of the valve body and corresponding recesses of the articulated arm prevent that the latter being lowered by any accidental pressure, in which case the valve rod would be displaced and an unwanted release of liquid would be produced. For delivering the carbonated liquid it is first necessary to release the folding strap. In this way the articulated arm may be unfolded until it displaces through the command channel existing on the head walls.
