Abstract: A capped liquid container comprises a liquid container for retaining liquid, having a supply opening formed for supplying the liquid to the recording devices of an ink jet recording apparatus, and a cap fixed to the liquid container for closing the supply opening, the cap being removed from the liquid container by rotating the cap. This cap is formed by a rigid member and an elastic member, and the elastic member is provided with first engagement means, and second engagement means is formed on the edge circumference of the supply opening to engage with the first engagement means. Then, the first engagement means and the second engagement means are pressed to be joined together, and at the same time, a part of the rigid member of the cap is fixed to the liquid container. With the structure thus arranged, the contact surface between the first and second engagement means produces the sealing effect, hence making it possible to materialize a capped liquid container having a high water tightness and air tightness. Further, when the liquid container is unsealed, it is easy to open the liquid container without causing liquid to spread externally with the provision of the rigid member for the cap which prevents the container from being pressed inwardly when being unsealed.

Abstract: A packaging structure of the present invention is provided for an ink tank (4) having an ink supply port (9) and an atmosphere communicating port (7A). It has a seal member (2) for sealing the ink supply port (9), a seal member (1, 1') for sealing the atmosphere communicating port (7A), and an integrated covering member (3, 3', 3'') for integrally covering the ink tank (4) having at least these seal members. A partial breakage of the covering member leads to open the atmosphere communicating port (7A) at first. Thus, the combination of the packaging structure and the ink tank (4) is constructed so as to open the atmosphere communicating port (7A) at first with reliability. It is functionally required at the time of pulling out the ink tank (4) from the package and also at the time of physical distribution without causing an ink leakage, regardless of the shape of the ink tank (4).
