PROBLEM TO BE SOLVED: To provide a foaming tool allowing a user to obtain only an amount that he/she prefers by setting in a container of foaming beverage such as beer.SOLUTION: A foaming tool for foaming beverage is so configured that: a taking-out pipe (2) for taking out drinking liquid from a foaming beverage container is branched into a fork-like shape so as to use one pipe as a main liquid pouring pipe (3) and the other as a foam liquid pouring pipe (4) a foam forming nozzle (C) is interposed in a duct of the foam liquid pouring pipe (4) and flow resistance to the drinking liquid is increased by passing through a nozzle space of the foam forming nozzle (C), and consequently, foaming is generated in the drinking liquid introduced into the foam liquid pouring pipe (4).SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】 ビールのような発泡飲料の容器にセットすることに依り、自分が好むだけの量の泡が得られるようにした泡立て用器具の提供を図る。【解決手段】発泡飲料容器内から飲用液を取り出すための取出しパイプ(2)を二股状に分岐させることに依って、一方のパイプを主液注ぎ用パイプ(3)とすると共に他方のパイプを泡液注ぎ出し用パイプ(4)とし、当該泡液注ぎ出し用パイプ(4)の管路内に泡形成用ノズル(C)を介在させ、当該泡形成用ノズル(C)のノズル間隙を通過させることに依り飲用液に対する流動抵抗の増大化を図り、これにより、泡液注ぎ出し用パイプ(4)内に導かれた飲用液の発泡化を生じさせるように構成した発泡飲料の泡立て用器具。【選択図】 図1
