PROBLEM TO BE SOLVED: To provide a dispense head that allows gas pressure to be reduced to a predetermined scheduled level of pressure so as for gas to be led into a liquid container even when a gas delivery pressure on the gas source side is higher than as scheduled. SOLUTION: An attachment is used for mounting a dispense head onto a container for cleaning storing cleaning liquid for a beer server, the dispense head being capable of sending the cleaning liquid into the beer server via a liquid port, as a pressurized gas being introduced thereinto via a gas port. The attachment includes: at its lower part, with a removable section to the mouthpiece of the container for cleaning; at its upper part, with a removable section to the dispensing head; and at its side part, with a pressure regulating valve. A primary side gas flow passage is formed that is in communication with a gas port, extended in the direction of the pressure regulating valve from the removable section to the dispensing head at the upper part of the attachment, while a secondary side gas flow passage is shaped that is in communication with the interior of the container for cleaning, extended in the direction of the removable section to the mouthpiece of the container for cleaning at the lower part of the attachment from the pressure regulating valve. The pressure regulating valve uses, for its valve opening, a side opening of either the primary side or secondary side gas flow passage, while it is so constituted as to be able to adjust the degree of opening of the valve opening so as for the gas pressure of the primary side gas flow passage to be reduced.
