PROBLEM TO BE SOLVED: To simplify the structure by manually opening a shutoff valve provided on a lid body to jet a washing liquid within the body of a vessel by a gas pressure of a contained foaming component through a washing path of a lid body. SOLUTION: The body of a vessel housing a washing liquid containing a foaming component is turned upside down to set a nozzle tube 30 at a specified angle. Under such a condition, a small-diameter hole 3a of a nozzle 3 is made to communicate with a path 25 of a ceiling wall 5b of a lid body 5. A nozzle port is positioned facing a washing object such as tooth and then a push button 6 is depressed. As a result, a valve body 8 is opened and the washing liquid flows to a hollow part of an internal wall 20 below the lid body 5, a central through hole and the path 25 of the ceiling wall 5b. Moreover, the washing liquid jets out by a pressure of a gas contained in the washing liquid at a nozzle port passing through the small-diameter hole 3a of the nozzle 3 and the nozzle tube 30. The washing liquid is consumed completely by one use, a cap 2 is removed and water and tablets are put into a vessel body to apply a lid. This allows preparations for the subsequent use. |
