PROBLEM TO BE SOLVED: To provide a foam discharger which hardly generates bacteria and hardly causes a sanitary problem in the foam device.SOLUTION: In a foam discharger 1, content liquid 82 containing an anti-bacteria agent and air are mixed to be foamed and then discharged by pressing a pump head part 3. A space 17 that is communicated with a second chamber 12 of a cylinder part 4 is provided between a cylindrical member 51 constituting a piston part 5 and a liquid introducing chamber 16 of a cylinder part 4. In the second chamber 12 of the cylinder part 4 is arranged a check valve 7 that can take in outer air. The foam discharger 1, when releasing pressing of the pump head part 3 to restore the part to the original position, opens the check valve 7 to take in the outer air therein by negative pressure generated inside the second chamber 12 and takes in the content fluid 82 therein through the gap 17. |
