Abstract

Connector for enabling fluid transfer between a first fluid container and a second fluid container, which connector comprises a first component that is arranged to be connected to a first fluid container and a second component that is arranged to be connected to a second fluid container. The first component is arranged to be non-rotatably connected to said second component before a second fluid container is connected to said second component and/or before a first fluid container is connected to the first component. The connector comprises a locking and rotation-enabling element that is arranged to be activated once a second fluid container has been connected to said second component, and/or once a first fluid container has been connected to the first component, which locking and rotation- enabling element enables the first component and the second component to rotate freely with respect to one another.

Claims

1. A connector for enabling fluid transfer between a first fluid container and a second fluid container, the connector comprising:

a first component that is arranged to be connected to a first fluid container and a second component that is arranged to be connected to a second fluid container, whereby said first component is arranged to be non-rotatably connected to said second component, or a part of the second component, and to a first fluid container before a second fluid container is connected to said second component or before a first fluid container is connected to the first component, wherein said connector comprises a locking and rotation-enabling element that is arranged to be activated once a second fluid container has been connected to said second component, or once a first fluid container has been connected to the first component, said locking and rotation-enabling element enables the first component and the second component to rotate freely with respect to one another, one of said first or second component comprises a guide portion to facilitate the connection of said first component to the second component.

2. A connector according to claim 1, wherein one of said first or second component comprises at least one protrusion that is arranged to become located in at least one corresponding cavity in the other of said first or second component or in said locking and rotation-enabling element, in order to connect said first component to said second component in a non-rotatable manner, and whereby said locking and rotation-enabling element is arranged to force said at least one protrusion out of said at least one corresponding cavity, whereby said first component and said second component are enabled to rotate freely with respect to one another when said at least one protrusion is forced out of said at least one corresponding cavity.

3. A connector according to claim 2, wherein said locking and rotation-enabling element is arranged to force said at least one protrusion out of said at least one corresponding cavity and into at least one slot, whereby said first component and said second component are enabled to rotate freely with respect to one another when said at least one protrusion is located in said at least one slot.

4. A connector according to claim 2, wherein said at least one protrusion defines said guide portion.

5. A connector according to claim 3, wherein said locking and rotation-enabling element is arranged to be automatically activated when said second fluid container is connected to said second component or once a first fluid container has been connected to the first component.

6. A connector according to claim 5, wherein said locking and rotation-enabling element is arranged to be automatically activated when it is directly or indirectly displaced by said second fluid container when said second fluid container is subsequently being connected to said second component, whereby said displacement of said locking and rotation-enabling element forces said at least one protrusion out of said at least one cavity or when it is directly or indirectly displaced by said first fluid container when said first fluid container is subsequently being connected to said first component, whereby said displacement of said locking and rotation-enabling element forces said at least one protrusion out of said at least one cavity.

7. A connector according to claim 2, wherein said locking and rotation-enabling element is arranged to be manually activated by a user after said second fluid container has been connected to said second component or when said first fluid container has been connected to said first component.

8. A connector according to claim 7, wherein said locking and rotation-enabling element is arranged to be manually activated by a user that directly or indirectly causes it to be displaced after said second fluid container has been connected to said second component or said first fluid container has been connected to said first component, whereby said displacement of said locking and rotation-enabling element forces said at least one protrusion out of said at least one cavity.

9. A connector according to claim 1, further comprising a snap fit mechanism to connect said first component to said second component or said fluid enabling element.

10. A connector according to claim 1, wherein said first component is arranged to be screwed into said second component.

11. A connector according to claim 1, wherein said first component is arranged to be slid into said second component.

12. A connector according to claim 1, wherein said second component or said first component comprises a membrane.

13. A connector according to claim 1, further comprising a sealing means to ensure that a fluid-tight, leak-free connection is made between the first fluid container and the second fluid container.

15. A connector according to claim 1, wherein said locking and rotation-enabling element is arranged to be manually activated by a user after said second fluid container has been connected to said second component or when said first fluid container has been connected to said first component.

16. A connector according to claim 4, wherein said guide portion comprises a wedge shaped portion.

17. A connector according to claim 1, wherein said guide portion is arranged to maintain contact with said locking and rotation-enabling element while the first and second components are being connected.

14. A fluid container comprising an integrally formed first component of a connector for enabling fluid transfer between said fluid container and a second fluid container, said connector comprising a second component that is arranged to be connected to said second fluid container, said first component is arranged to be non-rotatably connected to said second component, or a part of the second component, and to a first fluid container before a second fluid container is connected to said second component or before a first fluid container is connected to the first component, wherein said connector comprises a locking and rotation-enabling element that is arranged to be activated once a second fluid container has been connected to said second component, or once a first fluid container has been connected to the first component, said locking and rotation-enabling element enables the first component and the second component to rotate freely with respect to one another, one of said first or second component comprises a guide portion to facilitate the connection of said first component to the second component.
