Each discharged liquid agent flows in the connecting cylinder 27, the through hole 27a, and the seal cylinder 43 toward the nozzle cylinder 45 while maintaining a parallel state, and is discharged from the nozzle cylinder 45 without being mixed.
Thereafter, when the pressing head 41 is released, the stem 52 is lifted by the upward biasing force, the discharge valve is closed, and the lateral wall 25 and the pressing head 41 are returned to their original positions as the stem 52 is lifted.

Next, the case where the discharge container 1 is used in a state where the mixing member 60 is mounted on the nozzle cylinder 45 will be described.
In this case, the push-down head 41 is pushed down as in the case where the mixing member 60 is used in a state where it is detached from the nozzle tube 45. Then, each liquid agent discharged from the stem 52 and flowing toward the nozzle cylinder 45 as described above is mixed by passing through the blades 64 of the mixing portion 61 located in the nozzle cylinder 45, and the mixture of each liquid agent Is discharged from the discharge cylinder 62.

As described above, according to the discharge container 1 according to the present embodiment, the presence / absence of mixing can be switched by a simple operation of simply attaching / detaching the mixing member 60 to / from the nozzle cylinder 45.
For example, when a plurality of mixing members 60 having different shapes of the blades 64 of the mixing unit 61 are prepared, the degree of mixing can be easily switched by selecting the mixing member 60 to be mounted on the nozzle cylinder 45. In this case, it is possible to discharge an optimum mixture depending on the target degree of mixing.

Further, since the mixing unit 61 includes the wing body 64 having the pair of spiral plates 64a, when each liquid agent passes through the wing body 64, the flow direction of each liquid agent is effectively changed and mixed. Can do. Thereby, each liquid agent which passes the mixing part 61 can be mixed reliably.
Further, when the outer peripheral edge of each wing body 64 is in contact with the inner peripheral surface of the nozzle cylinder 45 as in the present embodiment, the mixing section 61 is connected to the nozzle when each liquid agent passes through the wing body 64. Each liquid agent that hardly shakes with respect to the cylinder 45 and passes through the mixing portion 61 passes between the outer peripheral edge of the wing body 64 and the inner peripheral surface of the nozzle cylinder 45, and does not pass through the wing body 64 without being discharged. It is prevented that it goes into the inside, and each liquid agent can be mixed more reliably.

The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
For example, three or more container main bodies 51 may be provided.
Further, the joint member 10 is not limited to the one shown in the above embodiment, and for example, the pressing lever 48 may not be provided.
