ABSTRACT:
An ink cartridge has a body comprised of a plurality of wall panels that are resiliently hinged to adjacent wall panels. The wall panels define a cavity within the body for storing ink when the body is in a full configuration. The body collapses from the full configuration to an empty configuration as ink is removed from the body. The wall panels collapse inwardly about the hinges to lie flat against one another to reduce the cavity volume. A frame frames the plurality of wall panels of the body. The frame resiliently expands as the wall panels collapse flat together within the frame. The resilient expansion of the frame and the panel collapse about the hinges biases the body toward the full configuration.
