[Previous technique #f] Please refer to "Fig. 1" and "Fig. 2". It is known that the gas valve sealing box is provided with a gas valve 2 on the sealed container 1, and the sealed container 1 is sealed by the air flow passage 4 by the air suction device 3. The air inside is withdrawn, and the gas valve 2 covers the surface of the sealed container 1 to close the air flow passage 4, and the inside of the sealed container 1 is maintained in a vacuum state to meet the demand for food preservation. And since the pressure outside the sealed container 1 is greater than the inside of the sealed container 1, an abutting force 5 is generated to press the gas valve 2 to close the air flow passage 4, so that the gas valve 2 can effectively block the gas while maintaining the sealed container 1 Vacuum. Please refer to Fig. 3, however, the sealed container 1 as shown in the figure is made of hard-shell plastic material and is formed by injection molding. When the injection is poor, the surface of the sealed container 1 will be uneven, so the valve 2 cannot be leveled. Covering the surface of the sealed container 1, there is a slight gap 6 between the gas valve 2 and the sealed container 1, which results in the inability to completely close the air flow passage 4, which maintains the vacuum in the sealed container 1 and is not even effective. The gas 7 is infiltrated and the vacuum inside the sealed container 1 cannot be maintained at all. Therefore, it is conventionally known that when the sealed container 1 is defective in ejection, the sealed container 1 can only be regarded as a defective product and discarded. Therefore, in order to increase the manufacturing yield of the sealed container 1, it is necessary to increase the process conditions of the injection molding, which leads to an increase in cost, and Inevitably, the sealed container 1 will have a certain amount of finished product, and its surface flatness cannot meet the demand. 099140264 Form No. A0101 Page 3 of 23 0992070145-0 201221814 [0005] Please refer to "Figure 4", if the sealed container 1 A is a soft material, it can be reduced with the volume of the storage 8 It is convenient to use without occupying space. However, after the air is sucked, the pressure on both sides of the air valve 2A is almost equal, so that the air valve 2A lacks the abutting force, and it is difficult to maintain the tight suction cover 9 of the sealed container 1A. , which causes the gas valve 2A to block the gas, has a poor effect, and has a problem of slowly leaking gas. [0006] Obviously, the conventional gas valve 2 has a high requirement for the surface flatness of the sealed container 1, so that it maintains the vacuum of the sealed container 1. The effect is not good enough to meet the demand for use, and the valve 2A is not suitable for the sealed container 1A of soft material. SUMMARY OF THE INVENTION [0007] Accordingly, the main object of the present invention is to disclose a vacuum pump that can effectively maintain the degree of vacuum, meeting the needs of use. [0008] The present invention is an opening for mounting on a sealed container, comprising a gas barrier film, a valve body and at least one air flow passage, wherein the valve body is snap-fitted to the opening, and the at least An air flow passage penetrates the valve body and communicates with the sealed container, and the gas barrier film is fixed to the valve body, and the gas barrier film is provided with an annular flange, and the annular flange is wound around the air passage. . According to this, when the sealed container assumes a vacuum state, at this time, since the annular flange is closed around the air passage, a dense gas barrier structure can be formed by the protrusion and deformation of the annular flange. The airtightness of the sealed container is maintained for a long time to meet the demand for use. [Embodiment] [0010] The structural design and technology of the present invention are specifically presented, and will be further described with reference to FIG. 099140264, Form No. A0101, Page 4/23, 0992070145-0 201221814. [0011] [0012] ❹ [0013] Please refer to FIG. 5, FIG. 6 and FIG. 7 as a first embodiment of the present invention for mounting on an opening 1 1 on a sealed container 1 The gas barrier film 20, a valve body 30, a card portion 4A and at least one air channel 50, wherein the gas barrier film 20 has an inner ring region 21 and an outer ring respectively disposed inside and outside. In the region 22, the center of the gas barrier film 20 extends upwardly with a convex twist 23' and the valve body 30 has a central hole μ extending to the bottom. The valve body 30 is locked and fixed to the opening η, and the blocking portion 4 is attached to the peripheral surface of the sealed container 10, and the gas barrier film 20 is pressed against the sealed container 1 The blocking portion can extend out of the three blocking piece ο, and the three blocking piece 41 presses against the sealed container 1 , and the at least one air flow path 8 <" , 50 can be formed in the valve The ring side of the body 3 更 extends to the inner ring region 21 of the gas barrier film 20, and the outer ring is provided with an annular flange 221 'the annular flange 221 Opening 11 and abutting the sealed container 10, please refer to FIG. 8 , FIG. 9 and FIG. 10 . The first embodiment can be used with an air extracting device 60 . The gas barrier film 20' is covered and pumped, and the outer ring region 22 of the gas barrier film 20 is turned over by the pressure difference to expose the at least one air flow path 5, at which time the sealed container 10 The gas is evacuated from the at least one airflow path 50 to bring the sealed container 10 into a vacuum state. When the air suction device 6 is no longer pumping, the gas barrier film 20 covers the opening 11, and the annular force of the annular flange 221 is compressed by the abutting force 70 generated by atmospheric pressure to tightly tighten. Abutting against the periphery of the opening 11, if the periphery of the opening 11 is a rough surface, the present invention can also fill the rugged surface by the deformation of the annular flange 221, and 099140264 Form No. A0101 Page 5 of 23 0992070145 -0 201221814 A dense gas barrier structure is formed which can maintain the vacuum degree of the sealed container 10 for a long time, and satisfies the demand for use. [0016] [0016] Please refer to FIG. 11 for a second embodiment of the present invention, wherein the outer periphery of the valve body 30A may be provided with a barb portion 32, and the valve body 30A The center of the gas barrier film is provided with a latching hole 33. The gas barrier film 20A is provided with a stud 24 corresponding to the engaging hole 33. The stud 24 is inserted into the engaging hole 33 to fix the gas barrier film 20A. The valve body 30A has two air flow passages 50A and is disposed on both sides of the engaging hole 33. The annular flange 221 is disposed around the gas barrier film 20A. Referring to FIG. 12, FIG. 13 and FIG. 14 again, the barb portion 32 allows the air extracting device 60 to be used at multiple angles, which increases the convenience of use, and the sealed container 10A is soft. The material is placed in a storage 80, and the air extracting device 60 is inserted into the barb portion 32. The air is extracted by the air extracting device 60, so that there is almost no air in the sealed container 10A. Therefore, the deposit 80 can be made less susceptible to damage. Moreover, since there is no pressure difference between the inside and the outside of the sealed container 10A, there is no squeezing force. However, the annular barrier 221 is provided on the gas barrier film, and the annular flange bulge can be caused by the annular flange. The deformation of the gas barrier film 20A generates a restoring force, and the gas barrier film 20A is in close contact with the valve body 30A, and the at least one air flow path 50 A is closed, resulting in a good gas barrier effect. The above is only the preferred embodiment of the invention, and is not intended to limit the scope of the invention. That is, the equivalent changes and modifications made by the scope of the patent application of the present invention are covered by the scope of the invention.
