Therefore, when the user presses the elastic top plate 211, the elastic top plate 211 is deformed and pressed toward the partition plate 212, so that the pressure of the closed space 213 is increased, and the air of the closed space 213 is forced to pass through the one-way row. The air portion 22 is discharged outside the casing 21; when the user releases the elastic top plate 211, the elastic top plate 211 is returned to the upwardly convex arc shape by the elastic force thereof, so that the closed space 213 is increased in volume. A negative pressure is generated, and the air inside the container 70 is sucked into the closed space 213 through the one-way suction portion 23, and after being repeatedly pressed and released, the air inside the container 70 can be completely sucked.  A vacuum is formed.  

Of course, in this example, the elastic top plate 211 is matched with the elastic force of the elastic member 40 in addition to the resetting property of the material itself in the process of returning upwardly convex; when the elastic top plate 211 is pressed and pressed When the elastic force of the elastic member 40 is greater than the elastic force of the elastic member 40, the elastic top plate 211 presses the elastic member 40 to form a compressed state. When the elastic top plate 211 is released, the elastic force of the elastic member 40 pushes the elastic top plate 211 upward. The elastic top plate 211 is returned to the upwardly convex convex arc shape by the resetting property of the material itself and assisted by the elastic force of the elastic member 40.

Based on the above-mentioned structural composition and technical characteristics, the following is the use of this creation:

As shown in Figures 5 and 5A, before the elastic top 211 is pressed,  The first one-way valve piece 223 of the one-way exhaust portion 22 abuts and closes the lower end of the exhaust assembly recess 2121, and the second valve piece 233 of the one-way suction portion 23 abuts and closes the suction The upper end of the recess 2122 is assembled, and air is still present inside the container 70. At this time, the elastic film 172A is pushed upward by the air pressure inside the container 70 and is convex upward and has an arc shape.  

As shown in FIGS. 6 and 6A, when the elastic top plate 211 is pressed and the pressure is greater than the elastic member 40 (such as the hollow arrow in FIG. 6), the elastic top plate 211 is deformed and deviated in the direction of the partition plate 212. And compressing the elastic member 40 to form a compressed state, thereby increasing the pressure of the closed space 213, forcing the air of the closed space 213 to flow through the plurality of first airflow recesses 224 of the one-way exhaust portion 22 to push the first elastic valve. The sheet 223 is finally discharged outside the casing 21 (as shown by the solid arrow in Fig. 6A, that is, discharged to the coupling groove 13 and discharged to the outside of the coupling groove 13).

As shown in FIGS. 7 and 7A, when the elastic top plate 211 is released (such as the hollow arrow in FIG. 7), the elastic top plate 211 is restored by the resetting of the material itself and the elastic force of the elastic member 40. Upwardly convexly arcuate, the closed space 213 is increased in volume to generate a negative pressure, forcing the second elastic valve piece 233 to move away from the suction assembly recess 2122, and the inside air of the container 70 is passed through the one-way suction portion. A plurality of second airflow recesses 234 of 23 are drawn into the enclosed space 213 (as shown by solid arrows in Figures 7 and 7A).

Thereby, after the pressing and releasing operations of the sixth and seventh figures are repeated, the air inside the container 70 can be completely sucked out to form a vacuum, that is, the state of the eighth and the figure. At this time, the elastic sealing member 172 The elastic film 172A is attracted to the inside of the container 70 to form a state of being recessed downward.

As shown in FIG. 9, when the side of the elastic sealing member 172 is pressed (as indicated by a hollow arrow in FIG. 9), the elastic sealing member 172 is compressed and deformed to form a gap with the pressure releasing assembly hole 171. The outside air enters the inside of the container 70 through the pressure releasing assembly hole 171, thereby balancing the inside of the container 70 with the external pressure, releasing the vacuum state (that is, returning to the state of Fig. 5).

As shown in FIG. 10, another embodiment of the present invention, wherein the inner surface of the bottom of the coupling groove 13 is provided with a recess 132, and the one-way exhaust portion 22 corresponds to the recess 132, when the air of the closed space 213 When the first elastic valve piece 223 is pushed, the concave portion 132 can increase the deformation space of the first elastic valve piece 233, so that air can be discharged outside the casing 21.
