The pump has a push support (27) movably mounted in translation on a cover (18) closing an opening of a hollow body (2) of a vial (1). The cover and the support have fluid extraction orifices provided with check valves, respectively. The support and the cover delimit a sucking chamber (29) to suck a fluid from the orifice of the cover. A spring element is molded with the cover and axially arranged between the cover and the support to maintain the support in a position spaced from the cover. The cover and the element are made of synthetic material. |
