Abstract
A refillable ink box proofed against the formation of airlocks during filling includes an ink storage chamber, a seat, and an insertion tube. The box includes a bottom plate, and first and second side walls. The bottom plate and first and second side walls form the ink storage chamber. The seat protrudes to the exterior and carries insertion tube, ink outlet, and air guiding port. The insertion tube defines the ink inlet and also an air vent. The ink inlet communicates with the ink outlet port, the ink outlet communicates with the ink storage chamber. The air guiding port equalizes gas pressure with outside atmosphere and is positioned above the ink outlet.
