Abstract

A fluid container cap includes a connection structure, a dispensing connector, and a movable restrictor that adjusts flow through the container cap is disclosed. A fluid container cap includes a connection structure, a dispensing connector, a restrictor, and a valve that is movably adjustable to alter fluid flow through the container cap is also disclosed.

First claim

What is claimed is:

1. A fluid container cap comprising:
a connection structure including an interior side and an exterior side configured to mate with a dispensing connector for dispensing fluid from the fluid container, portions of the connection structure defining a plug section and a bypass section; and
a restrictor located in a flow path defined in the connection structure and defining a restriction orifice, wherein a portion of the restrictor is configured for non-returnable movement in a direction from the exterior side toward the interior side from a first position in the plug section to a second position in the bypass section,
wherein in the first position of the restrictor, dispensing of the fluid through the connection structure is limited by the restriction orifice, and
wherein in the second position of the restrictor, dispensing of the fluid through the connection structure is through the restriction orifice and around the restrictor.

2. The cap of claim 1 , wherein the connection structure and the dispensing connector are configured to mate with the aid of one or more separate elements comprising at least one of a seal, a clamp, a fastener, or combination thereof.

3. The cap of claim 1 , wherein the restriction orifice comprises a cross-sectional area that is at least about 50% smaller than cross-sectional areas of other portions of flow paths through the connection structure and the dispensing connector.

4. The cap of claim 1 , wherein the restrictor comprises a monolithic element.

5. The cap of claim 1 , wherein the restrictor comprises at least one restriction orifice.

6. The cap of claim 1 , wherein the dispensing connector comprises an actuator structure which engages the restrictor and moves the restrictor from the first position to the second position.

7. The cap of claim 1 , wherein the connection structure further comprises a sleeve, wherein the sleeve is annular and defines an inner surface that contacts a guide portion of the restrictor.

8. The cap of claim 7 , wherein the sleeve includes the bypass section that is disposed toward the interior side of the connection structure and surrounds the restrictor.

9. The cap of claim 8 , wherein the bypass section is circumferentially discontinuous.

10. The cap of claim 8 , wherein the bypass section comprises one or more flow apertures or windows separated by ribs.

11. A fluid container cap comprising:
a connection structure including an interior side and an exterior side configured to mate with a dispensing connector for dispensing fluid from the fluid container, portions of the connection structure defining a plug section and a valve section comprising a movable valve; and
a restrictor located in a flow path defined in the connection structure and defining a restriction orifice, wherein a portion of the restrictor is configured for adjustable movement in a direction from the exterior side toward the interior side from a first position in the plug section to a second restricted position in the valve section and to a third unrestricted position in the valve section,
wherein in the first position of the restrictor, dispensing of the fluid through the connection structure is prohibited,
wherein in the second restricted position of the restrictor, dispensing of the fluid through the connection structure is limited by the restriction orifice, and
wherein in the third unrestricted position of the restrictor, dispensing of the fluid through the connection structure is through the restriction orifice, around the restrictor, and through at least one unrestricted bypass channel.

12. The cap of claim 11 , wherein the valve may operate to open, close, or adjust the flow path through the cap.

13. The cap of claim 11 , wherein the valve comprises one or more flow apertures or windows establishing fluid communication.

14. The cap of claim 11 , further comprising a sleeve, wherein the sleeve is annular and defines an inner surface that contacts an outer surface of the valve.

15. The cap of claim 14 , wherein the valve is movably adjustable with relation to the sleeve providing no flow path, a restricted flow path, and an unrestricted flow path.
