A device for packaging and dispensing a liquid or semi-liquid substance (P) in which a substance (P) in a receptacle (1), which is closed in a sealed manner firstly at a top by a cap (2) and secondly at a bottom by an internally movable punt (5), is compressed. The device includes an elastically deformable membrane (4) received in the top of the receptacle (1). The membrane (4) is formed by a substantially frustoconical axial valve (40) having a top portion provided with a central ejection orifice (41), a middle portion running into a channel section ring (42) and a bottom portion provided with a stretchable thin skirt (43) connected to a flange (44). The skirt (43) extends upwards along an internal wall of the receptacle (1). The flange (44) fixes the membrane (4) to the receptacle (1). A nozzle-forming tube (3) passes axially through the cap (2) of the receptacle (1). The tube (3) has a top end (31) projecting outside the receptacle (1) and an internal bottom end. The bottom end is provided with an element for bearing against the membrane (4) and a closure element (33) for closing the ejection orifice (41).
