PROBLEM TO BE SOLVED: To simply and surely prevent beverage blowout from a beverage extraction path.SOLUTION: There are included an operation valve 7 for opening/closing from the outside a beverage extraction path 6 leading beverage from a beverage storage chamber 3 to the outside, and an automatic valve 8 for opening/closing the beverage extraction path 6 from the beverage storage chamber 3. The automatic valve 8 is configured from: a valve hole part 12 provided on the beverage extraction path 6; a valve body 13 capable of opening/closing the valve hole part 12; a valve case part 14 for guiding the valve body 13 to the opposite direction to the valve hole part 12; and an elastic member 15 installed in a state of supporting the valve body 13 in a valve opening position away from the valve hole part 12, and resisting the valve closing movement of the valve body 13. The elastic member 15 is included between the periphery of the valve hole part 12 and the valve body 13. The valve body 13 is covered by the valve case part 14 in the opposite direction from a beverage storage chamber 3 side. As a result of these, the automatic valve 8 is provided in a compact manner, and a setting that the elastic member 15 is surely pressed by a pressure difference near the valve body 13 during an abnormal time is simplified so as to rapidly suppress beverage blowout. |
