Abstract

A device for transferring a fluid to and/or from a fluid container having a sealing member. The device includes a piercing member for penetrating the sealing member and an elongated body defining a longitudinal flow channel through which a fluid may flow into and/or out of the fluid container and at least one opening that communicates with the flow channel. The at least one opening is arranged to extend along at least 1% of the length (l) of the piercing member to ensure that at least part of the at least one opening (20) is located substantially adjacent to the innermost side of a sealing member when the device is in use.

Claims

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.

2. The device according to claim 1, wherein the plurality of openings extends substantially along the entire length (l) of the piercing member.

3. The device according to claim 2, wherein the plurality of openings are uniformly spaced along the length (l) of the piercing member.

4. The device according to claim 1, wherein the plurality of openings are uniformly spaced along the length (l) of the piercing member.

5. The device according to claim 1, wherein the plurality of openings is arranged to extend along at least 50% of the length (l) of the piercing member.

6. The device according to claim 1 further comprising connecting means to connect it to the fluid container.

7. The device according to claim 6, wherein the connecting means comprises multiple resilient arms configured to slidably engage a rim on the fluid container.

8. The device according to claim 1 further comprising a ruled scale on the piercing member.

9. The device according to claim 1, wherein the plurality of openings is disposed behind the tip of the piercing member.

10. The device according to claim 1, wherein the plurality of openings is arranged to extend along at least 70% of the length (l) of the piercing member.

11. The device according to claim 10, wherein the plurality of openings are uniformly spaced along the length (l) of the piercing member.

12. A sealing member for sealing an inlet or an outlet of a fluid container, comprising a device that is integrally formed with the sealing member or releasably or non-releasably connected thereto, wherein said device comprises

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 being sized to allow for 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.

13. The sealing member according to claim 12, wherein the device is slidably mounted on the sealing member so that the plurality of openings of the device may be opened and closed by sliding the device back and forth with respect to the sealing member.

14. A fluid container, comprising a sealing member according to claim 12 or 13.

15. The device according to claim 12, wherein said device is releasably connected to said sealing member.

16. The device according to claim 15, wherein the plurality of openings are uniformly spaced along the length (l) of the piercing member.

17. The device according to claim 15, further comprising connecting means to connect it to the fluid container.

18. The device according to claim 12, wherein said sealing member is a rubber, plastic, or elastomeric bung, stopper, membrane, or puncturable.

19. 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;

an opening 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 the opening extends at least 50% of the maximum width of the piercing member to ensure that at least part of the opening is located substantially adjacent to the innermost side of said sealing member when the device is in use;

an elastic retractable sleeve arranged to at least partly cover and seal the opening 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 opening which is 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 the opening; and

an air inlet disposed on the elongated body.
