In order to discharge the contents from the discharge container 1, the user pushes down the operation unit 40 with a finger. When the operation unit 40 is pushed down, first, the head body member 25 slides downward with respect to the sliding member 24 to swing the swing member 27, and the poppet valve member 28 is urged by the coil spring 29. The third delivery valve 43c (discharge port 12) is opened (see FIG. 3). When the operation unit 40 is further pushed down, the lower stem member 20 that descends against the urging force of the coil spring 19 lowers the poppet valve member 18 by the frictional force of the contact surface, and the suction valve 42 (pump chamber 41). Close the lower end) (see FIG. 3). Further, when the lower stem member 20 is lowered, the lower stem member 20 slides downward with respect to the piston member 21 to open the first delivery valve 43a (upper end of the pump chamber 41) (see FIG. 3). By further pushing down the operation unit 40, the volume of the pump chamber 41 is reduced (see FIG. 3), the contents in the pump chamber 41 are sent out toward the discharge port 12, and the contents are discharged from the discharge port 12 (see FIG. 3). See the straight solid arrow in FIG. 3).

Then, when the pressing of the operation unit 40 is released, first, the lower stem member 20 that rises by the urging force of the coil spring 19 raises the poppet valve member 18 by the frictional force of the contact surface, and the suction valve 42 (pump). The lower end of the chamber 41) is opened. Further, as the lower stem member 20 rises, the lower stem member 20 slides upward with respect to the piston member 21 to close the first delivery valve 43a (upper end of the pump chamber 41). As the lower stem member 20 further rises, the volume of the pump chamber 41 increases and the inside of the pump chamber 41 is depressurized, and the contents in the accommodation space S are transferred from both the lower suction port 10 and the upper suction port 11 to the pump chamber 41. It is sucked toward. At this time, the second liquid L2 located below is sucked from the lower suction port 10 (see the lower two-dot chain line arrow in FIG. 3), and the first liquid L1 located above is sucked from the upper suction port 11 (see the lower two-dot chain line arrow in FIG. 3). See the upper two-dot chain arrow in FIG. 3). When the contents are sucked in this way, the inner layer body 7 is volume-reduced and deformed to reduce the accommodation space S, and the outside air is introduced between the inner layer body 7 and the outer layer body 9 through the outside air introduction port 8. Therefore, even if the contents are discharged, the shape of the outer layer 9 is maintained, so that the outer shape of the container body 2 is maintained, while the height of the liquid level of the contents is also maintained, and the periphery of the upper suction port 11. The state in which the first liquid L1 is located is maintained. Therefore, even if the discharge of the contents progresses, the contents of the desired mixing ratio of the first liquid L1 and the second liquid L2 are supplied to the pump chamber 41. The mixing ratio can be appropriately set by adjusting the cross-sectional area of the openings between the lower suction port 10 and the upper suction port 11. Further, according to the container body 2 having such an inner layer 7 and an outer layer 9, contact between the contents and air can be suppressed, and the quality of the contents can be maintained satisfactorily. In the present embodiment, since the lower suction port 10 is formed by a plurality of (four) openings 36 arranged in the circumferential direction of the additional member 17, the lower suction port 10 is formed even when the volume reduction deformation of the inner layer body 7 progresses. The occurrence of blockage can be suppressed.

When the suction valve 42 is opened by releasing the push-down of the operation unit 40, and the convex portion formed on the outer peripheral surface of the poppet valve member 18 comes into contact with the lower end of the coil spring 19, the poppet valve member 18 is prevented from rising. The stem member 20 slides upward with respect to the upper portion of the poppet valve member 18, and sucks back (pulls in) the contents from the discharge port 12 toward the inside of the lower stem member 20. Further, at this time, the ball valve body 23 also sucks back the contents by lowering due to its own weight. Then, the poppet valve member 28 moves to the tip side by the urging force of the coil spring 29, and the discharge port 12 is closed. Therefore, dripping of the contents from the discharge port 12 is suppressed.

By repeating pushing down and releasing the operation unit 40 as described above, the contents of the desired mixing ratio of the first liquid L1 and the second liquid L2 can be obtained from the suction valve 42, the pump chamber 41, and the first delivery valve. In the process of passing through 43a, the second delivery valve 43b, and the third delivery valve 43c, the mixture can be appropriately mixed and discharged from the discharge port 12.

And have. Therefore, in the discharge container 1 according to the present embodiment, the content liquid sucked from the upper suction port 11 and the content liquid sucked from the lower suction port 10 are mixed by colliding with each other in the process of flowing inside the pump device 3. , Can be discharged from the discharge port 12. Therefore, according to the discharge container 1 according to the present embodiment, the contents of the separated liquid can be appropriately mixed and discharged without the need for a hand-waving operation of the container. Further, in the conventional container having the discharge cap as described above, the discharge amount of the contents tends to vary depending on the operation method, but according to the discharge container 1 according to the present embodiment, the amount can be quantified by making the pump device 3 full stroke. Discharge becomes possible.
