The procedure for mixing the two liquids using the two liquid mixing container 1 according to the present embodiment is as follows. First, the user removes the opening / closing lid member 23 from the guide wall 16c, covers the guide wall 16c on the mouth portion 4a of the second container main body 4, and puts the pressing portion 8 on the mouth portion 4a as shown in FIG. Place on the top. In this state, when the user pushes down the first container main body 2, the operating portion 11 advances with respect to the fixed portion 7, the volume of the pump chamber 12 decreases, and the internal pressure of the pump chamber 12 rises. At this time, the opening / closing portion 27 is urged in the forward direction with respect to the hollow rod-shaped portion 26 by the elastic body 29 via the inclined surface 28. Therefore, even if the internal pressure of the pump chamber 12 rises as the first container main body 2 is pushed down, the opening / closing portion 27 does not immediately recede with respect to the hollow rod-shaped portion 26, and the pump chamber 12 and the through port 24 It is possible to maintain the state in which the communication of the pump chamber 12 is cut off and to enable the accumulation of pressure in the pump chamber 12.

In the present embodiment, since the air chamber 31 is provided in the pump chamber 12, the operating portion 11 can be advanced while compressing the air, which is a compressible fluid, with the accumulating pressure. Therefore, the operating force required for pushing down the first container main body 2 can be reduced, and the usability can be improved.

When the piston 9 reaches the upper end of the cylinder 6, the advance of the piston 9 is stopped by the stepped portion 17f formed between the upper end of the cylinder 6 and the lower end of the upper cylinder 17c. Then, due to the further advancement of the actuating portion 11 (of which the rod-shaped member 19, the pressing member 21 and the nozzle tip member 22), the piston member 20 resists the urging force of the elastic body 29 as shown in FIGS. 3 to 5. Then, it retracts with respect to the rod-shaped member 19. That is, the free end (upper end) of the elastic body 29 is elastically displaced outward in the radial direction by the inclined surface 28, so that the inclined surface 28 is allowed to descend, that is, the piston member 20 is allowed to descend. As a result, the opening / closing portion 27 retracts with respect to the hollow rod-shaped portion 26, and the pump chamber 12 and the through port 24 communicate with each other.

As a result, the first content liquid C1 accumulated in the pump chamber 12 is ejected from the pump chamber 12 through the through port 24, the inner space of the rod-shaped member 19, and the inner space of the nozzle tip member 22 from the ejection port 10. do. Therefore, the first content liquid C1 vigorously rushes into the second content liquid C2 housed in the storage space S2 of the second container main body 4, thereby mixing with the second content liquid C2. Therefore, according to the two-liquid mixing container 1 according to the present embodiment, it is possible to reduce the need to shake and mix the first content liquid C1 after introducing it into the second container main body 4. Further, by pushing down the first container main body 2 with a full stroke, the quantitative first content liquid C1 corresponding to this full stroke can be introduced into the second container main body 4. Therefore, according to the two-liquid mixing container 1 according to the present embodiment, quantitative mixing can be easily performed.

When the depressing of the first container main body 2 is released, the operating portion 11 retracts due to the urging force of the coil spring 14, and first, the opening / closing portion 27 advances with respect to the hollow rod-shaped portion 26, and the pump chamber 12 and the through port 24 Block communication. Then, due to the further retreat of the operating portion 11, the volume of the pump chamber 12 increases, the internal pressure of the pump chamber 12 decreases, and the pressure becomes negative with respect to the internal pressure of the accommodation space S1. Due to the negative pressure, as shown in FIG. 6, the valve body 18a separates from the annular convex portion 17e, and the first content liquid C1 flows from the accommodation space S1 into the pump chamber 12. At this time, the air compressed inside the air chamber 31 expands inside the air chamber 31 with the negative pressure.

Then, the two-liquid mixing container 1 returns to the state as shown in FIG. When it is desired to mix a further amount of the first content liquid C1, the user may repeat the above-mentioned pressing operation of the first container main body 2 from this state.

As a first modification of the present embodiment, as shown in FIG. 7, a communication port 32 that covers the opening (lower end opening) formed by the lower end of the surrounding wall 30 and communicates the air chamber 31 and the pump chamber 12 is provided. A lid 33 with a communication port may be provided. In this modification, the lid 33 with a communication port is a cylinder that is erected on the covering wall 33a that covers the lower end opening of the surrounding wall 30 and that can be fitted to the inner peripheral surface of the peripheral wall of the surrounding wall 30. It is provided with a fitting cylinder wall 33b having a shape. Further, the covering wall 33a is connected to the lower end of the surrounding wall 30 via a hinge 34. However, the lid 33 with a communication port may be provided separately from the valve member 18. Further, in this modification, the communication port 32 is composed of only one hole formed in the center of the covering wall 33a. Further, the hole is set to a size that makes it difficult for air to pass through. The number, arrangement, shape, and the like of the holes constituting the communication port 32 can be appropriately changed according to the viscosity and the like of the first content liquid C1.

According to such a configuration, it is possible to easily hold the air inside the air chamber 31 even when the first container 1a falls down, so that stable operation of the first container 1a can be ensured. ..

Further, the frame body 36 is connected to the lower end of the surrounding wall 30 via a hinge 37. However, the frame body 36 may be provided separately from the valve member 18.

According to such a configuration, even if the first container 1a falls down, air can be reliably held inside the air chamber 31, so that stable operation of the first container 1a can be ensured. ..

It goes without saying that the above-described embodiment is merely an example of the embodiment of the present invention and can be variously modified without departing from the gist of the invention.

For example, in the above-described embodiment, the opening / closing lid 15 is configured separately from the mounting member 16, but may be connected to the mounting member 16 via a hinge. Further, the opening / closing lid 15 may not be provided.
