Abstract

Device (24) for transferring a fluid (22) to and/or from a fluid container (12) having a sealing member (14). The device (24) comprises a piercing member (16) for penetrating the sealing member (14) and an elongated body defining a longitudinal flow channel (18) through which a fluid (22) may flow into and/or out of the fluid container (12) and at least one opening (20) that communicates with the flow channel (18). Said at least one opening (20) is arranged to extend along at least 1% of the length (l) of the piercing member (16) to ensure that at least part of said at least one opening (20) is located substantially adjacent to the innermost side (14b) of a sealing member (14) when the device is in use.

Claims

1. A device for transferring a fluid to and/or from a fluid container having sealing member, the device comprising:

a piercing member 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; and

at least one opening that communicates with the flow channel and that 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 is located substantially adjacent to the innermost side of a sealing member when the device is in use.

2. The device according to claim 1, wherein the at least one opening is arranged to extend along at least 2%, or at least 3%, or at least 4%, or at least 5%, or at least 10% of the length (l) of the piercing member.

3. The device according to claim 1, wherein the at least one opening extends substantially along the entire length (l) of the piercing member.

4. The device according to claim 1, further comprising a plurality of openings that are uniformly or non-uniformly spaced along the length (l) of the piercing member.

5. The device according to claim 1, further comprising a retractable sleeve arranged to at least partly cover and seal the at least one opening when the device has not been inserted into a sealing member of a fluid container whereby the sleeve is arranged to abut against the outermost side of the sealing member when the device has been inserted into a sealing member of a fluid container and the retracted as the piercing member penetrates more deeply into the sealing 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 1 further comprising a ruled scale.

8. A sealing member, such as a rubber, plastic or elastomeric bung, stopper, membrane or puncturable cap, for sealing an inlet/outlet of a fluid container, comprising a device according to claim 1 that is integrally formed with the sealing member or releasably/non-releasably connected thereto.

9. The sealing member according to claim 8, wherein the device is slidably mounted on the sealing member so that the at least one opening of the device may be opened and closed by sliding the device back and forth with respect to the sealing member.

10. A fluid container, comprising a sealing member according to claim 8 or 9.

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

12. The device according to claim 1, wherein the at least one opening is arranged to extend alone or at least 20%, or at least 30%, or at least 50% of the length (l) of the piercing member.

13. The device according to claim 12, further comprising a plurality of opening that are uniformly or non-uniformly spaced along the length (l) of the piercing member.

14. The device according to claim 12, further comprising a retractable sleeve arranged to at least partly cover and seal the at least one opening when the device has not been inserted into a sealing member of a fluid container, whereby the sleeve is arranged to abut against the outermost side of the sealing member when the device has been inserted into a sealing member of a fluid container and be retracted as the piercing member penetrates more deeply into the sealing member.

15. The device according to claim 12, further comprising connecting means to connect it to the fluid container.

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

17. The device according to claim 16, further comprising a plurality of openings that are uniformly or non-uniformly spaced along the length (l) of the piercing member.

18. The device according to claim 17, further comprising a retractable sleeve arranged to at least partly cover and seal the at least one opening when the device has not been inserted into a sealing member of a fluid container, whereby the sleeve is arranged to abut against the outermost side of the sealing member when the device has been inserted into a sealing member of a fluid container and be retracted as the piercing member penetrates more deeply into the sealing member.

19. The device according to claim 3, further comprising a plurality of openings that are uniformly or non-uniformly spaced along the length (l) of the piercing member.

20. The device according to claim 19, further comprising a retractable sleeve arranged to at least partly cover and seal the at least one opening when the device has not been inserted into a sealing member of a fluid container, whereby the sleeve is arranged to abut against the outermost side of the sealing member when the device has been inserted into a sealing member of a fluid container and be retracted as the piercing member penetrates more deeply into the sealing member.
