1. An electronic smoking device, comprising:
a liquid reservoir adapted for storing liquid,
an atomizer configured to atomize liquid stored in the liquid reservoir, and
a central passage that is adapted to conduct atomized liquid,
a docking valve for docking a source of liquid to be stored in the liquid reservoir,
a liquid duct adapted to receive liquid from the docking valve and open into the refillable liquid reservoir, and
a valve for releasing gas from the refillable liquid reservoir when refilling the refillable liquid reservoir, the valve comprising a flexible sealing element and a counter sealing element with a curved shape, wherein the flexible sealing element comprises a free end with a surface area that is forced against the curved shape of the counter sealing element for an improved seal in a first position and wherein the flexible sealing element is configured to deform to release air from the refillable liquid reservoir in a second position.
