1. A device for transferring a fluid to a fluid container, or from a fluid container, or both to and from a fluid container, wherein said fluid container comprises a sealing member having an innermost side and an outermost side, the device comprising:

  • a piercing member having a tip for penetrating the sealing member;

    an elongated body defining a longitudinal flow channel through which a fluid may flow into and/or out of the fluid container, the elongated body having a greater width than the width of the piercing member;

    a plurality of openings that communicates with the flow channel and that is arranged to extend along at least 30% of the length (l) of the piercing member and each opening of the plurality of openings extends at least 50% of the maximum width of the piercing member to ensure that at least part of the plurality of openings is located substantially adjacent to the innermost side of said sealing member when the device is in use, each of the openings sized to allow a passage of liquids;

    an elastic retractable sleeve arranged to at least partly cover and seal the plurality of openings when the device has not been inserted into said sealing member of said fluid container, wherein said sleeve is arranged to abut against the outermost side of said sealing member when the device has been inserted into said sealing member of said fluid container and be retracted as the piercing member penetrates more deeply into said sealing member such that the retractable sleeve will cover and seal only a portion of the plurality of openings which are located outwards of the outermost side of the sealing member when the device is in use and thus prevent any fluid from leaking out of said plurality of openings; and

    an air inlet disposed on the elongated body.
