Abstract:
1. A fluid container unit configured by integrally-assembling a first container and a second container for respectively accumulating different kinds of fluids in a parallel arrangement, the fluid container unit comprising: a container coupling for coupling a first supply/discharge port located at one end of the first container with a second supply/discharge port located at one end of the second container; a single nozzle member having a nozzle tube; a connection cap having a first end for holding a base portion of the nozzle member and a second end for covering one side of the container coupling by fitting around an outer periphery thereof; an intermediate adaptor having a pair of pusher elements facing the first supply/discharge port and the second supply/discharge port respectively, the intermediate adaptor being held movably in a direction along a longitudinal axis of the nozzle tube in the connection cap; and a supply/discharge port opening mechanism for moving the intermediate adaptor toward the container coupling and opening the first supply/discharge port and the second supply/discharge port by the pair of pusher elements, wherein the base portion of the nozzle member is held rotatably around the longitudinal axis of the nozzle tube at the first end of the connection cap; wherein the nozzle member is configured so as to be capable of being removably fixed to an injection site of fluid usage equipment; wherein the supply/discharge port opening mechanism comprises a first inclined surface part which is provided on an inner surface of the nozzle member and is inclined along a rotational direction of the nozzle member, and a second inclined surface part which is provided on an outer surface of the intermediate adaptor so as to be associated with the first inclined surface part; and wherein rotating the nozzle member by a required angle in one direction causes the first inclined surface part to rotate by a required angle in one direction and to push the second inclined surface part in a direction that is opposite the nozzle member side, thereby moving the intermediate adaptor forward toward the container coupling by a predetermined amount and opening the first supply/discharge port and the second supply/discharge port by the pair of pusher elements.
