An air suction hole 4e for sucking outside air between the outer container and the inner container 2 is formed in the outer container 3. An outside air introducing hole 10 communicating the air suction hole 4e with the outside is formed in the dispensing cap 6. The valve cylinder 7 includes an air valve 7a switching the communication and the interruption between the air suction hole 4e and the outside air introducing hole 10 and a dispensing valve 7b switching the communication and the interruption between the connection passage 7A and the dispensing opening 5. The dispensing valve 7b has a structure serving as a check valve regulating the flow from the dispensing opening 5 side to the connection passage 7A side, and allows the flow toward the reverse direction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
