A packaging structure of the present invention is provided for an ink tank having an ink supply port and an atmosphere communicating port. It has a seal member for sealing the ink supply port, a seal member for sealing the atmosphere communicating port, and an integrated covering member for integrally covering the ink tank having at least these seal members. A partial breakage of the covering member leads to open the atmosphere communicating port at first. Thus, the combination of the packaging structure and the ink tank is constructed so as to open the atmosphere communicating port at first with reliability. It is functionally required at the time of pulling out the ink tank from the package and also at the time of physical distribution without causing an ink leakage, regardless of the shape of the ink tank.
