A fluid substance dispenser including a container defining an elongate chamber to contain the fluid substance. The container is closed at one end by a movable piston and at its other end by a transverse fixed wall from which there extends, outwards from the chamber, an elongate appendix the free end of which is positioned to correspond with a hole provided in a deformable cap defining with the fixed wall a compression chamber. The edge of the cap is elastically urged to seal against said end when the cap is in its rest state, whereas it separates partly from it when the cap is pressed to dispense the fluid substance.
