Abstract:
1. A flexible polymeric container having opposed sidewalls defining a chamber comprising: a fluid access member having a generally cylindrical wall defining a fluid passageway in fluid communication with the chamber, the generally cylindrical wall having a first end and a second end and openings at each of the first and second ends into the fluid passageway, a flange extends radially outward from the first end of the cylindrical wall and has a surface attached to one of the opposed sidewalls; and a rigid evacuation structure pivotally mounted to an inner surface of the cylindrical wall and extends across the opening at the first end, the evacuation structure being moveable from a fluid fill position where a portion of the evacuation structure extends into the chamber to a fluid evacuation position where a portion of the evacuation member extends along a line essentially parallel to the surface of the flange, the evacuation structure having a first member for preventing the container sidewall from blocking fluid flow through the fluid passageway when the evacuation structure is in the evacuation position, and a second member for allowing fluid to flow through the opening at the first end, wherein the evacuation structure moves to the fill position in response to the filling of the container with liquid and to the evacuation position in response to the removal of liquid through the fluid access member.
