An auxiliary through-hole 13 is provided immediately below the constriction 10 at the upper position of the tip of the nozzle 8 so as to communicate with the inside of the container 2. It is more preferable that the suction of the solution from the nozzle 8 be performed more effectively even if the number of the nozzles decreases.

The piston portion 5 is provided with a piston cylinder rod 14 into which a solution can freely enter, and an upper pressing spring 15 and a lower pressing spring 16 which is stronger than the upper pressing spring 15 on the piston cylindrical rod 14. 3 comprises a two-stage piston 17 which is vertically movable and closely contacted, and a lid 19 which is fixed to the cylinder 3 via a seal 18.

The upper pressing spring 15 is provided on an upper portion 22 located above a boundary portion 21 of the two-stage piston 17 so as to directly transmit the pressing of the piston cylinder rod 14.
The lower pressing spring 16 having a pressure higher than 5
Is provided in the lower stage portion 23 so that the pressing force of the piston cylinder bar 14 is indirectly transmitted through the upper stage pressing spring 15 and the boundary portion 21, and a through hole 20 is provided in a side portion of the lower end portion of the piston cylinder bar 14. By pressing against the upper pressing spring 15 of the piston cylinder rod 14, the two-stage piston 17 can freely project below the tip of the two-stage piston 17, so that the solution in the cylinder 3 can flow in and out.

The distal end of the lower pressing spring 16 is capable of restricting the downward movement by abutting against the latching portion 9 and freely contacting the coil spring 12 so that the spherical valve 11 can be pressed against the narrowed portion 10.

The fixing portion 6 is fixed to the lid 19 and can be fixed to the mouth 25 of the container 2.
Is provided so that the solution from the inside of the piston cylinder rod 14 can be discharged freely.

The bottom 1a of the container 2 is flexible and
It is made of a material having good close contact with the inner wall surface, and is formed in a disk shape by a thick peripheral wall portion 1a and a thin central surface portion 1b. A radial rib 27 is provided on the central surface portion 1b to reduce the pressure.
It is preferable to prevent deformation due to vacuum pressure.

[0014]

The present invention is embodied as described above. To use the present invention, first, the mouth 2 of the container 2 containing the cosmetic liquid or the like is used.
The fixing part 6 is fixed to 5. By pressing the pressing portion 7 with a fingertip, the piston cylinder rod 14 presses the upper pressing spring 15, and the concealed through hole 20 is protruded to make the cylinder-3.
At the same time as the solution in cylinder-3
From the cylinder-cylinder rod 14.

By further pressing the two-stage piston 17
Is lowered, and by pressing down the lower pressing spring 16,
The through hole 20 is exposed in the cylinder-3, the solution in the cylinder-3 enters the piston cylinder rod 14, and the cylinder rod 14
The solution inside is extruded, and the overflowing solution is discharged from the discharge port 27.

When the two-stage piston 17 is hooked on the step portion 4, the pressing of the pressing portion 7 is released, the two-stage piston 17 is raised by the lower-stage pressing spring 16, and the inside of the cylinder 3 is depressurized and vacuumed, and the spherical valve 11 Rises against the coil spring 12, the solution in the container 2 enters the cylinder 3 from the nozzle 8,
At the same time, the bottom 1 rises.

At the time when the solution in the container 2 is sucked from the nozzle 8, the air staying in the upper portion of the container 2 (the air is also sealed in the container when the solution is filled) is first sucked through the auxiliary through hole 13. Thereafter, the solution is sucked and discharged from the auxiliary through hole 13 and the nozzle 8.

[0018]

As described above, according to the present invention, in a device for sucking and discharging a solution in a container whose bottom rises from the top by decompression / vacuum pressure, a piston portion capable of traveling a certain distance in a cylinder and a cylinder. And a fixing part and a pressing part,
The cylinder is provided with a latching portion and a constricted portion inside the vicinity of the nozzle at the tip, and a coil spring having a pressure that presses an upwardly movable spherical valve to the constricted portion so as to be in close contact with a pressure that does not hinder the solution suction. A piston cylinder rod into which a solution can freely enter, a two-stage piston closely contacted with the piston cylinder rod via an upper pressing spring and a lower pressing spring,
The upper pressing spring is provided at the upper part of the two-stage piston to directly transmit the pressure of the piston cylinder bar, and the lower pressing spring is provided at the lower part of the piston. The pressing force of the cylinder bar is transmitted indirectly via the upper pressing spring, and a through hole is provided on the side of the lower end of the piston cylinder bar, so that the piston cylinder bar is pressed against the upper pressing spring. The solution inside the cylinder can freely enter by freely projecting below the tip of the two-stage piston, and the tip of the lower-stage pressing spring strikes the hook and regulates the downward movement, and can freely contact the coil spring. The fixing part is fixed to the lid and can be fixed to the mouth of the container, and the pressing part has a discharge port at the tip so that the solution can be discharged from the piston cylinder rod. Contact is reduced as much as possible Inner prevents the oxidation of the solution becomes sealed, always provide a solution, such as high-quality milk.

Even when the amount of the solution in the container is low, the spherical valve is in close contact with the constriction without swinging, so that there is no danger of air entering the container and the solution can always be smoothly discharged. In addition, since most of the internal solution is sucked and discharged, it can be used without waste.

Since an auxiliary through-hole is provided just below the constriction at the upper position of the tip of the nozzle, the air staying in the upper part of the container 2 is sucked and discharged before the solution is sucked, so that the smooth solution Suction and discharge can be performed, and even when the amount of the solution decreases, only the solution can be suctioned and discharged, so that use can be made without waste.

Further, the bottom of the container is made of a material which is entirely flexible and has good close contact with the inner wall surface of the container, and is constituted by a thick peripheral wall and a thin center surface, and a radial surface is formed on the center surface. Since the ribs are provided to prevent deformation due to reduced pressure / vacuum pressure, the ribs smoothly rise without being deformed even when a strong pressure is applied, so that the entire material can be saved and it is economical.
