SOLUTION: A pump housing 7 has a liquid inflow port 5 and a liquid outflow port 6. A pump body 12 has at least one pump means 21. The pump body 12 has an elastic member 13 expanded by the pump means 21. By the expansion of the elastic member 13, pumping action is applied to fluid food 2 inside the pump housing 7. The fluid food 2 is discharged from the outflow port 6. By the contraction of the elastic member 13, the fluid food 2 is suctioned from the liquid inflow port 5 into the pump housing 7. |
