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 (11)

1. 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 flexible cage positioned proximate the bottom end of the passageway and including:

an outer portion, the outer portion secured in the base of the spout;

an inner portion, the inner portion comprising a top surface, a bottom surface, and a central bore extending between the top surface and the bottom surface, the top surface including a plurality of top protrusions with a plurality of top gaps between the top protrusions, the bottom surface including a plurality of bottom protrusions with a plurality of bottom gaps between the bottom protrusions; and

a plurality of flexible arms, the flexible arms connecting the inner and outer portions;

wherein:

the flexible cage having a first position wherein the flexible arms are deflected and the bottom protrusions extend a first distance below the spout base to be 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; and

the flexible cage having a second position wherein the flexible arms are not deflected and the bottom protrusions are closer to the spout base than they are when cage is in the first position.

2. The system of claim 1 , wherein the outer portion further comprises a plurality of outer protrusions with a plurality of gaps between the outer protrusions, the outer protrusions extending below the base of the spout.

3. The system of claim 1 , wherein the system further comprises an evacuation member, the evacuation member comprising a head and a body, the head configured to be inserted into the central bore and the body configured to extend into the container, the head and body forming a duct from within the container to the flexible cage.
