Abstract

The present application relates to a system for evacuating fluid from a flexible container. The system includes a spout connected to a flexible container. A passageway within the spout is in fluid communication with an inside of the flexible container, and the passageway has a top end and a bottom end. An evacuation facilitating structure is positioned proximate the bottom end of the passageway and has a fluid channel therethrough. The evacuation facilitating structure blocks portions of the wall of the flexible container from entering the bottom end of the passageway and preventing fluid from evacuating the container via the passageway.

Claims (24)

1. A system for evacuating fluid from a flexible container, comprising:

a spout having a base with an outer rim, the spout being configured to be connected to one of a plurality of walls of the flexible container and a passageway in fluid communication with an interior region of the flexible container, the passageway having an outlet at a top end and an inlet at a bottom end; and

a cage positioned proximate the bottom end of the passageway and including a circular cage rim that is received in a groove in the base of the spout and mounted along the base of the spout proximate the inlet, wherein the cage rim defines the outer perimeter of the cage, the cage being positioned to block a portion of one of the plurality of walls of the flexible container from entering the inlet of the passageway and preventing fluid from evacuating the container via the passageway.

2. The system of claim 1 , wherein the cage arcs downward below the base of the spout.

3. The system of claim 1 , wherein the cage is detachably connected to the spout.

4. The system of claim 3 , wherein the cage is detachably connected to the base via a bayonet connecting arrangement.

5. The system of claim 1 , wherein the cage includes a plurality of intersecting bars that define a plurality of gaps through which fluid can flow into the spout.

6. A system for evacuating fluid from a flexible container, comprising:

a spout having a base that is configured to be connected to one of a plurality of walls of the flexible container and a passageway in fluid communication with an interior region of the flexible container, the passageway having an outlet at a top end and an inlet at a bottom end; and

a plurality of legs that extend downward from the base of the spout and that are located entirely below the base of the spout, wherein the legs extend a first distance down from the base of the spout that is greater than a second distance the legs extend parallel to the base of the spout, the legs being positioned to block a portion of one of the plurality of walls of the flexible container from entering the inlet of the passageway and preventing fluid from evacuating the container via the passageway while allowing fluid to pass between the plurality of legs.

7. The system of claim 6 , further including at least one bridge that extends between at least two of the plurality of legs.

8. The system of claim 7 , wherein the bridge defines at least one gap through which fluid can flow into the spout.

9. The system of claim 7 , further including a connector that is slidably received in the passageway and that includes a bottom portion that can be moved to a position below the base of the spout and above the bridge.

10. The system of claim 6 , further including a connector that is slidably received in the passageway and that includes a bottom portion that extends below the base of the spout.

11. The system of claim 10 , wherein the connector includes at least one cutout along the bottom portion that allows fluid to flow into the spout.

12. The system of claim 10 , wherein the connector includes at least one slot along the bottom portion that allows fluid to flow into the spout.

13. The system of claim 10 , wherein the connector can be moved within the passageway between a first position and second position, wherein when the connector is in the first position, the bottom portion of the connector does not extend below the base of the spout and when the connector is in the second position, the bottom portion of the connector extends below the base of the spout.

14. A system for evacuating fluid from a flexible container, comprising:

a spout having a base that is configured to be connected to one of a plurality of walls of the flexible container and a passageway in fluid communication with an interior region of the flexible container, the passageway having an outlet at a top end and an inlet at a bottom end; and

an insertable member that is slidably received in the passageway and that can be moved within the passageway between a first position and second position, wherein when the insertable member is in the first position, a bottom portion of the insertable member does not extend below the base of the spout and when the insertable member is in the second position, the bottom portion of the insertable member extends below the base of the spout and is positioned to block a portion of one of the plurality of walls of the flexible container from entering the inlet of the passageway and preventing fluid from evacuating the container via the passageway, the insertable member having an open bottom end that defines an inlet such that fluid can flow into the insertable member when it is in the first position and when it is in the second position.

15. The system of claim 14 , wherein the insertable member includes a second passageway that extends therethrough through which fluid can flow.

16. The system of claim 15 , wherein the insertable member includes at least one cutout along the bottom portion that allows fluid to flow into the spout and the second passageway when the insertable member is in the second position.

17. The system of claim 15 , wherein the insertable member includes at least one slot along the bottom portion that allows fluid to flow into the spout and the second passageway when the insertable member is in the second position.

18. The system of claim 15 , wherein the insertable member includes a cage at the bottom thereof that defines gaps that allows fluid to flow into the spout and the second passageway when the insertable member is in the second position.
