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 a first engagement portion, while a second engagement portion is formed on the edge circumference of the supply opening to engage with the first engagement portion. Then, the first engagement portion and the second engagement portion are sealingly pressed 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 portions produces the sealing effect, hence making it possible to fabricate 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 to the cap which prevents the container from being passed inwardly when being unsealed.
