The operation of the present invention will be described below.

When the device of the present invention is installed in a container 10 in which contents such as shampoo or cosmetics are accommodated, an initial state is obtained. Thus, in the initial state before the device of the present invention is operated, the first accommodating part 21 and the second accommodating part are provided. There is no content in (22).

In this way, in the initial state in which the container 10 is standing upright, as shown in FIG. 4, when the nozzle part 33 of the moving member 30 is pressed by hand, the moving member 30 moves downward in the housing 20. While the second inlet hole 36 inserted into the partition 23 is blocked into the second accommodating part 22, the second stopper 32 integrally formed with the moving member 30 is also present. The second inlet 26 by pushing the elastic means 50 under the movement and the elastic means 50 to push down the second valve 42 to open the second valve 42 while moving downward To be closed.

At this time, since the air is filled for the first time without the contents contained in the second accommodating portion 22, when the second stopper 32 moves downward, the air at the lower portion of the second stopper 32 decreases in volume. Due to the upward movement through the gap between the wall of the second stopper 32 and the housing 20, it is discharged to the nozzle unit 33 through the second inlet hole (36).

In this state, when the pressing force applied to the nozzle unit 33 is released, the moving member 30 moves upward as shown in FIG. 3 by the restoring force of the elastic means 50. At this time, the second stopper 32 As the) moves upward, the external force applied to the second valve 42 is released to open the second inlet 26.

When the second stopper 32 continues to move upward while the second inlet 26 is opened in this way, a vacuum force is formed at a lower portion thereof, and the contents contained in the container 10 are stored in the second inlet 26. Entering into the second receiving portion 22 through, press the nozzle unit 33 once more in this state, while repeating the same state as shown in Figure 4 again this time the contents filled in the lower portion of the second stopper (32) Pressed by the second stopper 32 while being raised up through the gap between the housing 20 and the second stopper 32 and discharged to the nozzle unit 33 through the second inlet 36. will be.

On the other hand, while the container 10 is used upright while the contents of the inside is reduced and the contents do not flow into the second receiving portion 22 through the second inlet 26, the container 10 as shown in FIG. Turn over and turn upside down.

When the container 10 is placed upside down, the upper cross-sectional area of the container 10 is narrower than the bottom of the container 10 so that the contents can be collected more easily. In this state, the container 10 is upside down and the nozzle part 33 is turned upside down. In the non-pressing state, as shown in FIG. 5, the pressurizing portion 34 of the movable member 30 presses the first valve 41 due to the force of the elastic water stop 50 so that the first inlet 25 is closed. It is closed so that contents cannot enter the first accommodating part 21.

In this state, as shown in FIG. 6, when the nozzle part 33 is pressed, the pressurizing part 34 of the moving member 30 is released from the first valve 41, and the first valve 41 is connected to the first inlet ( 25) is opened, and in this state, the first stopper 31 moves upward to form a vacuum force on the first accommodating portion 21 so that the contents are out of the housing 20 by the vacuum force. It enters the receiving portion 21.

Here, the first stopper 31 and the second stopper 32 maintain a predetermined gap with the wall of the housing 20, but the gap does not affect the formation of the vacuum force.

When the pressing force applied to the nozzle unit 33 is released while the contents enter the first accommodating part 21, the pressurizing part 34 presses the first valve 41 to press the first valve. When the first stopper 31 descends downward while the first inlet 25 is closed by opening (41), the contents under the first stopper 31 are compressed due to volume reduction. The movable member (1) moves up through the first stopper 31 through the gap between the first stopper 31 and the wall of the housing 20 and is exposed to the first accommodating part 21. 30 is discharged to the nozzle unit 33 through the inside.

According to the present invention as described above, even if it is difficult to discharge the container in the upright state because the contents of the cosmetics, etc. contained in the container, it is possible to discharge the remaining content in the upright state without opening the lid The hassle of having to discharge the contents by opening the lid and shaking the container as before has been improved.

In addition, since the present invention can discharge the remaining contents without opening the lid, it is inconvenient to use when the contents remain a little to prevent the contents are discarded is very economical and the environment is polluted by the discarded contents It can also prevent.
