PROBLEM TO BE SOLVED: To use by hand-push with a foam discharge container inverted downward, and secure a certain level of foam quality.SOLUTION: A container main body is pressed and deformed and air is introduced from an air introducing passage to a gas-liquid mixing chamber with a foam discharge passage turned downward. A liquid is introduced to the gas-liquid mixing chamber from a liquid introducing passage. Foam obtained by mixing the air and the liquid in the gas-liquid mixing chamber is discharged from the foam discharge passage. Pressure deformation of the container main body is released, and the air from an external area is introduced in the liquid together with the foam from the foam discharge passage through an external air introducing passage. Furthermore, the air is inhaled in a space in the container main body. By repeating pressure deformation and release of the pressure deformation of the container main body, a certain amount of foam can be discharged. |
