The present invention provides a discharging container whose main part is a squeeze-bottle adapted for use as eyedroppers and transparent to such a degree as required. This container has to perfectly shut off ambient air and bacteria not to flowing into a liquid content of the container so as to keep it sterilized even after unsealed for use. The discharging container has a laminated bottle 2, and a stopper 3 attached to a finish 2a of the laminated bottle, the bottle being composed of an outer layer 21 and an inner layer 22 delaminating from the outer layer 21. A vent hole 4 is formed in the outer layer so as to introduce ambient air in between the outer and inner layers 21, 22. A discharging passage 10 is formed in the stopper 3 so as to exude through it a liquid content inside the inner layer 22, and the stopper further has a check valve 8 and a filter 7 disposed on the downstream side of the valve.
