Thereby, the whole 2nd discharge channel | path connects, and the 2nd content of the upper accommodating part 16 can be discharged outside. Since the 1st channel | path is closed at this time, the 1st content of the lower storage part 15 does not mix. Note that when the push button 45 is rotated 90 degrees, if the retaining piece 55 interferes with the holder 44 and cannot be lowered, a discharge device capable of switching to a locked state in which neither the upper or lower contents can be discharged is obtained. It is done. At this time, since the two protrusions 54 are arranged in a direction perpendicular to the discharge direction, the consumer can recognize that the discharge cannot be performed visually. Since the two-liquid discharge device 10 operates as described above, different contents filled in the upper and lower storage units can be used properly according to the situation. Moreover, it can also mix after discharging as needed.

  The two-liquid discharge device 10 in FIG. 1 extracts the push button 45 from the stem 25, rotates it around the vertical axis, and fits the stem again to switch the discharge passage.
