A dispensing device for relatively fluid substances, consisting of a container (1) with a pump (4) having a tubular housing (5) and a vent (5e) which is sealed when the piston is in its starting position, a flexible member (3) connected to the pump beneath said vent via a socket (2) forming a ring with a cylindrical skirt (2b) joined to an upper hoop (2a) as well as a centring and supporting flange (2c, 2e) on the container, and an outer flange (7a) forming a sealed connection between the pump and the container while a passage (2f) links the lower intermediate space (1c) around the flexible member to the upper intermediate space (1b) linked to the vent. The preservation of the substance is improved and air venting and filling are simplified. |
