Abstract
A liquid storage container includes a supply port for supplying the liquid, and liquid path forming structure provided within the liquid container for preventing direct backflow of liquid in the container to the supply port. The liquid path forming structure is detachable from the liquid container and includes a projecting member having a sloped surface provided below the supply port. The liquid path forming structure also includes structure for defining a first flow path for passing liquid therethrough. This structure includes a lowermost section of the sloped surface and defines a first port. The liquid path forming structure also includes structure for defining a second flow path for passing liquid into the container. This structure includes a portion of the projecting member and defines a second port. The second port is in communication with a lowermost portion of the second flow path, and the first port is in communication with an intermediate portion of the second flow path.
