In the hand draft A having the above-described structure, a carbonated soft drink of syrup cola selected according to a customer's order is dispensed into cups and provided. Occasionally, it is pointed out that the carbonated drink is weak in carbonic acid and lacks carbonation. In particular, in the case of cola, it is often required that carbonic acid is more effective.

[0009] This hand draft A was originally developed in a foreign country, and in the country of development, it is made so that it can be poured out as a carbonated beverage suitable for the taste of customers. In Japan, many people want something with a high level of carbonic acid, because the heat is removed by foaming with carbonic acid.

[0010] For this purpose, the carbonated water to be mixed with the syrup cola may be combined so that the carbonic acid does not escape from the syrup. The hand draft A is a pipe for pouring out the carbonated water. The end on the downstream side of the passage 10a is divided into a number of small-diameter branch pipes 100 that radially divide, and the openings a are formed in the neck of the reduced-diameter section 5a on the lower end side of the discharge shaft section 5.

By pouring out from the spout 60 at the lower end of the nozzle 6, originally, a structure is formed that weakens the impulse that causes carbonic acid to escape when discharging carbonated water and merging with syrup and cola. Therefore, there is a difficult problem in modifying the hand draft so that a carbonated beverage with a strong carbonated content can be poured out according to the taste of the customer.

[0011] The present invention solves this problem and provides a new means for pouring a carbonated carbonated beverage with strong hand-draft without major changes and without breaking the basic structure. The purpose is to do.
