Abstract:
An ink container for providing ink to an ink jet printing system, the ink container having a fluid outlet for fluidically communicating with a fluid inlet of the ink jet printing system, the fluid inlet having a hollow needle having a blunt end and a lateral hole, the ink container including:a resilient body member at the fluid outlet, the resilient body member including:a first sealing surface for tightly receiving the hollow needle to prevent fluid passage between an outer surface of the hollow needle and the first sealing surface when the ink container is in fluid communication with the ink jet printing system, the first sealing surface having a leading edge and a trailing edge relative to a direction of insertion of the hollow tubular member into the first sealing surface;a second sealing surface for receiving a movable sealing member, wherein the movable sealing member is biased against the second sealing surface when the hollow needle is at least partially removed from the first sealing surface; anda debris accumulation region at the trailing edge of the first sealing surface, wherein the debris accumulation region sufficiently spaces the second sealing surface and thereby the movable sealing member from the trailing edge of the first sealing surface so that the movable sealing member does not contact the trailing edge of the first sealing surface and debris resulting from movement of the hollow needle relative to the first sealing surface accumulates within the debris accumulation region and does not prevent the movable sealing member from seating with the second sealing surface.
