Reduced leakage ink container opening

A method of opening an ink container, the method comprising:

• lowering a pressure in an interior of the container;
• and
• after lowering the pressure in the container interior, opening the container interior to the ambient environment;
• wherein lowering the pressure in the interior comprises expanding an interior volume of the container.

A fluid container comprising:

• a plurality of container walls forming a housing;
• a fluid port through one of the container walls;
• an expansion element comprising a deformable wall portion of one of the container walls;
• an opening element attached to the deformable wall portion for moving the deformable wail portion from an inner position to an outer position;
• a seal closing the fluid port.

A liquid ink container comprising:

• a plurality of exterior container walls forming a housing having a housing interior;
• a divider dividing the housing interior into a capillary chamber and a free ink chamber;
• a conduit through the divider to fluidly connect the capillary chamber and the free ink chamber;
• an ink port through a first one of the exterior container walls into the capillary chamber;
• a removable seal closing the ink port;
• a vent through a second one of the exterior container walls into the capillary chamber;
• an expansion element formed as a deformable portion of a third one of the exterior container walls at the free ink chamber;
• wherein the expansion element has an inner position in which the deformable wall portion is deformed toward the interior of the housing, and an outer position in which the deformable wall portion is deformed toward the exterior of the housing;
• and
• an opening element attached to the deformable portion of the third exterior container wall for selectively moving the expansion element from its inner position to its outer position.
