Abstract
The coupling structure includes a container side joint and a main body side joint. The container side joint includes a container opening/closing valve, a container side communication passage, a backflow prevention valve and a protrusion. The container opening/closing valve is brought into contact with the protrusion by a pressure of the liquid filled in the container side communication passage. The main body side joint includes a main body opening/closing valve and a main body side communication passage. When the main body opening/closing valve pushes the container opening/closing valve at a coupling of the container side joint and the main body side joint, the container opening/closing valve is pushed in a coupling direction, is also tilted and is separated from the protrusion to communicate the container side communication passage with the main body side communication passage.
