PROBLEM TO BE SOLVED: To safely remove a dispensing head by releasing the pressure of carbon dioxide in a tank for washing when the dispensing head is removed from the tank for washing. SOLUTION: This tank T for washing a dispenser is equipped with a tank main body 1 to house a washing liquid, and a fitting body 3. In this case, the fitting body 3 is attached to the mouth section 10 of the tank main body 1, and detachably fits the dispensing head 2 on the tank main body 1. In such a tank T for washing the dispenser, a residual pressure releasing mechanism 4 is formed. The residual pressure releasing mechanism 4 is equipped with a residual pressure releasing port 43 and a movable element 5. In this case, the residual pressure releasing port 43 goes through the side section of the fitting body 3. The movable element 5 is engaged with the dispensing head 2 fitted by the fitting body 3, and at the same time, opens/closes the residual pressure releasing port 43 accompanying the handle operation of the dispensing head 2. Thus, by lifting the handle 21 of the dispensing head 2 after a washing work of the dispenser, the engagement between the dispensing head 2 and the movable element 5 is released. At the same time, the residual pressure releasing port 43 opens, and the dispensing head 2 can be safely removed after the press-feeding gas residing in the tank main body 1 has been released to the outside.
