Abstract

A connector for transferring a fluid includes a first connector and a second connector. Each connector includes a first outer portion including a first obstructive portion and defining a first fluid passageway for receiving a fluid therein. Each connector further includes a first central nozzle coupled to the first outer portion. The central nozzle includes a first engagement member. The first central nozzle is movable between a first position and a second position with rotation of the first outer portion. In the first position, the first obstructive portion and the first engagement portion substantially overlap to impede fluid flow through the first fluid passageway. In the second position, at least one of the first engagement member and the first obstructive member is displaced to allow fluid flow through the first fluid passageway.

Claims

1. A connector for transferring a fluid, the connector comprising:

a first connector including;

a first outer portion including a first obstructive portion and defining a first fluid passageway for receiving a fluid therein; and

a first central nozzle coupled to the first outer portion, the central nozzle including a first engagement portion, wherein at least one of the first central nozzle and the first outer portion is rotatably movable relative to the other between a first position and a second position, wherein in the first position the first obstructive portion and the first engagement portion substantially overlap to impede fluid flow through the first fluid passageway, and in the second position, at least one of the first engagement portion and the first obstructive portion is displaced to allow fluid flow through the first fluid passageway; and

a second connector including;

a second outer portion including a second obstructive portion and defining a second fluid passageway for receiving a fluid therein; and

a second central nozzle coupled to the second outer portion, the second central nozzle including a second engagement portion, wherein at least one of the second central nozzle and the second outer portion is rotatably movable relative to the other between a first position and a second position, wherein in the second position the second obstructive portion and the second engagement portion substantially overlap to impede fluid flow through the second fluid passageway, and in the second position, at least one of the second engagement portion and the second obstructive portion is displaced to allow fluid flow through the second fluid passageway;

wherein the first and second connectors are engageable and movable between non-connected and connected positions, wherein in the non-connected position, the first fluid passageway and second fluid passageway are obstructed, and in the connected position, the first fluid passageway and second fluid passageway are in fluid communication with one another.

2. A connector as defined in claim 1, wherein the connector is movable to a connected position by coupling the first connector and second connector and rotating at least one of the first connector and second connector relative to the other.

3. A connector as defined in claim 1, wherein one of the engagement portion and the obstructive portion is moved to allow fluid flow through the second fluid passageway.

4. A connector as defined in claim 1, wherein the first central nozzle and the second central nozzle are formed of materials having different shrinkage than the first and second outer portions, respectively, said different shrinkage being selected to define a desired level of friction therebetween.

5. A connector as defined in claim 1, wherein at least a portion of the connector includes an indicator of a field of use.

6. A connectors as defined in claim 5, wherein the indicator is a color.

7. A connectors as defined in claim 5, wherein the indicator is at least one dimension of the first and second connectors.

8. A connectors as defined in claim 5, wherein the indicator is a shape of a portion of the first and second connectors.

9. A connector as defined in claim 1, wherein the first obstructive portion is fixed relative to all other portions of the first outer portion.

10. A connector as defined in claim 1, wherein in the second position the at least one of the first engagement portion and the first obstructive portion is rotationally displaced relative to each other.

11. A connector as defined in claim 1, wherein the second obstructive portion is fixed relative to all other portions of the second outer portion.

12. A connector as defined in claim 1, wherein in the second position the at least one of the second engagement portion and the second obstructive portion is rotationally displaced relative to each other.

13. A method comprising the following steps:

(i) positioning or maintaining a first connector connected to one end of a first conduit in a closed position to, in turn, maintain a fluid hermetically sealed within the first conduit, wherein a first nozzle of the first connector is in fluid communication with the first conduit and is recessed within a first housing of the first connector to prevent contamination of the first nozzle, and at least one of the first nozzle and the first housing are rotatably movable relative the other;

(ii) interconnecting the first connector to a second connector connected to one end of a second conduit and positioned in a closed position that maintains the second conduit sealed with respect to ambient atmosphere, wherein a second nozzle of the second connector is in fluid communication with the second conduit and is recessed within a second housing of the second connector to prevent contamination of the second nozzle, and at least one of the second nozzle and the second housing are rotatably movable relative to the other; and

(iii) moving at least one of the first and second connectors or portions thereof from the closed to an open position and, in turn, placing the first and second nozzles in fluid communication with each other to allow fluid to flow from the first conduit, through the first and second nozzles, and into the second conduit without exposing the fluid to ambient atmosphere.

14. A method as defined in claim 13, further comprising the step of introducing fluid into the first conduit and, in turn, allowing the fluid to flow from the first conduit, through the first and second nozzles, and into the second conduit without exposing the fluid to ambient atmosphere.

15. A method as defined in claim 13, wherein the interconnecting step includes engaging first and second engagement portions of the first and second nozzles, the moving step includes rotating at least one of the first and second nozzles relative to the other to move from the closed to the open position, and the method further comprising preventing rotation of the first and second engagement portions relative to each other during the interconnecting and moving steps.

16. A method as defined in claim 13, wherein the first and second connectors are formed using a dual sequential injection procedure.

17. A method as defined in claim 13, wherein the moving step includes rotating both the first connector and the second connector.

18. A method as defined in claim 13, wherein the moving step includes at least one of (i) rotating at least one of the first nozzle and the first housing relative to the other, and (ii) rotating at least one of the second nozzle and the second housing relative to the other.

19. A connector system comprising:

at least two connectors, each including an outer portion including an obstructive portion and defining a fluid passageway for receiving a fluid therein; and

a nozzle coupled to the outer portion, the nozzle including an engagement portion, at least one of the nozzle and the obstructive portion being rotatably movable relative to the other between a first position and a second position, wherein in the first position the obstructive portion and the nozzle substantially overlap to impede fluid flow through the fluid passageway, and in the second position, at least one of the nozzle portion and the obstructive portion is displaced to allow fluid flow through the fluid passageway, wherein the at least two connectors are engageable and movable between non-connected and connected positions, wherein in the non-connected position, the first fluid passageway and second fluid passageway are obstructed, and in the connected position, the first fluid passageway and second fluid passageway are in fluid communication with one another.
