Abstract:
1. A device for dispensing at least one liquid, said device comprising: a dispenser head including a pumping mechanism for suction and dispensing of at least one liquid; a liquid container having at least one inner compartment accessible through an opening for the coupling of the container to the dispenser head, such opening being delimited by an annular rim which extends around a geometric axis, and a vent flange disposed between the dispenser head and the liquid container, said vent flange comprising a) an annular wall inserted in the container through the opening, wherein the annular wall comprises at least one vent wall arranged so as to separate, at least partially, the inner compartment from environment external to said compartment, and wherein at least one vent conduit connecting the inner compartment with the environment passes through said annular wall, b) a filter functioning with the vent conduit, allowing the passage of gaseous fluids through the conduit and preventing the passage of the liquid to the environment, wherein the filter occupies a coupling area on the vent wall, and c) a tubular element enabling the liquid to travel from the inner compartment towards the pumping mechanism, the annular wall being positioned in an annular manner externally to the tubular element, wherein the coupling area, comprises a coupling surface which is flat, and the coupling surface and the geometric axis are not perpendicular to one another.
