1. Trigger-type dispensing head for actuating a stem of a valve of a pressurized container, comprising:
an insert provided with
a cam surface, and
cooperating means for cooperating with the stem of the valve of the container to actuate the valve when the cam surface is moved towards the pressurized container,
a ring,
a lever articulated on the ring, so that the lever can pivot relative to the ring about a pivot axis, the lever being provided with
a trigger, and
at least one cam follower configured to follow the cam surface,
the dispensing head being configured to allow relative rotation of the lever with respect to the cam surface about a main axis between a closed position in which the cam follower or followers cannot move the cam surface towards the container to actuate the valve, and an open position in which the cam follower or followers can press on the cam surface and move it towards the container, thus actuating the valve,
wherein
the insert is configured to be blocked in rotation relative to the container and to the stem of the valve,
the ring is an adjustment ring which is configured to rotate relative to the container and to the insert about the main axis to bring the lever and the cam follower or followers into the open or closed position,
the cam surface having at least one ramp inclined relative to a radial plane perpendicular to the main axis so as to connect two points offset angularly and located in two planes offset axially relative to the main axis.
