An applicator device for a free-flowing substance includes a carrier body provided with an application device at one end and a pin at an opposing end. A transverse channel penetrates the pin, and an axial channel branching off from the transverse channel leads to the application device. A reservoir device having a ring-shaped edge seal sealingly engages the pin, whereby the applicator device is activated by displacing the reservoir device on the pin toward the application device to open a flow connection between the reservoir device and the transverse channel. The reservoir device has a receptacle segment that is elastically deformable at least in portions so that, when the applicator device is activated and a flow connection between the transverse channel and the receptacle segment exists, the free-flowing substance is discharged via the application device by manual compression of the elastically deformable area of the receptacle segment.
