A device for the application of a liquid fluid to a peripheral area of a lid using pistols for injecting said liquid fluid. The device includes an articulated mechanical device combined with at least two coaxial tubular shafts: a main supply shaft and a lower shaft, where a lower end of the main supply shaft connects to a first part of the articulated mechanical device, while a second part of the articulated mechanical device connects to a lower end of the lower shaft. The two coaxial tubular shafts rotate independently by means of transmission devices. The main supply shaft is arranged in an inner hole of the lower shaft, which is arranged coaxially around at least one section of the main supply shaft.
