Further, the rotating member B ₂ and the top plate portion 53 of the discharge port member B ₃ are provided with marks indicating the communication state of the first flow path p _{1 and} the communication state of the second flow path p ₂ . The marks are an arrow 38 provided at a predetermined position on the edge of the top wall 31 of the rotating member B ₂ , and a first mark 55 and a second mark 56 having a triangular shape provided at predetermined positions on the periphery of the top plate 53 of the discharge port member B _3. The third mark 57 and the fourth mark 58 are included. Each state appears when the arrow 38 matches each mark. In the case of the first mark 55, the first flow path p ₁ and the second flow path p ₂ are cut off, in the case of the second mark 56, the first flow path p ₁ is communicated with the second flow road p ₂ are cut off, in the case of the third mark 57, the first flow path p ₁ is blocked, the second flow path p ₂ is in communication, in the case of the fourth mark 58, the The first flow path p ₁ and the second flow path p ₂ are blocked.

The case where the double tube container 1 comprised as mentioned above is used is demonstrated. In the state of FIG. 1, as shown in FIG. 4, one end surface of one locking plate 21 is in contact with one end surface of the rib 39, and the arrow 38 matches the first mark 55. Furthermore, the first communication hole 17a and the second communication hole 17b is in a state where the first flow path p ₁ and the second flow path p ₂ is closed is blocked by the seal cylinder 30.

From this state, when the peripheral wall 32 of the rotating member B ₂ is grasped and rotated counterclockwise, and the arrow 38 is aligned with the second mark 56 as shown in FIG. 5, the first through hole 17a has a first through hole. 35a overlap and the first flow path p ₁ is communicated as shown in Figure 2. At this time, it can be seen that the convex portion 37 got over the diaphragm 19 immediately before that, and both of them overlapped auditorily and visually. If squeezing first body 2a in this state, receiving liquid via a first flow path p ₁ Open first discharge valve 5a, is discharged from the discharge port 54. In this case the second flow path p ₂ is cut off.

Next, when the rotating member B ₂ is further rotated counterclockwise and the arrow 38 is aligned with the third mark 57 as shown in FIG. 6, the second through hole 35b overlaps the second communication hole 17b. As shown in FIG. 3, the second flow path p ₂ communicates. Also at this time, it can be seen that the convex portion 37 got over the diaphragm 19 immediately before and the both overlapped. So if squeezing the second body portion 2b, accommodating liquid through the second flow path p ₂ by opening the second discharge valve 5b, it is discharged from the discharge port 54. At this time, the first flow path p ₁ is blocked. Then, when the further match the fourth mark 58 the arrow 38 by rotating the rotating member B ₂ counterclockwise, the second communication hole 17b is also closed by a seal tube 30, the first flow path p ₁ and a second stream a state of road p ₂ are both shut off. In this case, as shown in FIG. 7, the other end surface of the rib 39 abuts on one end surface of the other locking plate 21, and further rotation is impossible.

In the above example, the first flow path p ₁ and the second flow path p ₂ are joined to one discharge port 54. However, as shown in the second embodiment in FIG. a first discharge port 54a of road p ₁ is communicated, the second flow path p ₂ may be opened separately and second discharge port 54b communicating.
