At groove 131 is disposed around the side wall ' of the convex ring portion 13 and the first groove 131 is connected to the top portion; a second concave f, 132 ring 1 is disposed The outer ring side of the convex ring portion 13 is located, and the second groove 132 is close to the top ring of the convex ring portion 130, and the first sealing ring of the piece is formed. The first recesses 31 are partially exposed and disposed on the top portion, and a + second sealing ring 221 is inserted into the second recess 22i and partially exposed. In this way, the two sides of the 彳闵 a 曰 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目200900330 The application of the present invention is such that the first sealing ring 210 can be embedded in the inner portion of the first sealing ring 210 and form a plane (as shown in FIG. 6). The structure of the cover 100 is explained. As shown in the cross-sectional view of Fig. 8, the cover 100 of the present invention, when the opening of the container 300 is to be covered, is partially sealed after the partial collar portion 130 is inserted into the opening of the container 300. The ring 220 will be squeezed between the convex ring portion 130 and the inner wall of the container 300. At this time, due to the imbalance of the pressure inside and outside the container 300, the cover 100 will not be easily covered, and the convex portion 130 cannot be completely plugged. The opening of the container 300 is entered. At this time, in the present invention, the diaphragm 161 is pressed up by the pressing portion 162 of the ventilation umbrella valve 160 by the deflation function of the ventilation umbrella valve 160, and the container 300 is balanced by the air hole 103 in the cover 100. The pressure of the inner and outer sides causes the convex ring portion 130 and the second sealing ring 220 to continue to be inserted into the opening of the container 300 until the first sealing ring 210 above the abutting portion 110 and the opening of the container 300 The top edge 310 is in conflict. When the user no longer presses the pressing portion 162, the cover 100 separates the internal space of the container 300 from the outside by the first sealing ring 210 and the second sealing ring 220 formed by the elastic material to form a sealed state. . For the vacuuming, as shown in the sectional view of FIG. 9 , the recess 102 is recessed downwardly on the upper surface of the cover 100, and the sleeve 102 is disposed in the recess 101, which is more convenient for the user. The action of drawing air on the recess 101 is performed by a manual air extracting device 400. When evacuated (for example, by suctioning the recess 101 by the manual air extracting device 400), the diaphragm 161 is attracted by the airflow and lifted upward, and the air inside the container 300 can be emptied by the air holes 103. Withdrawn, when the inside of the container 300 is in a vacuum, and the pumping action is no longer performed in the 200900330, the diaphragm 161 on the breathable umbrella valve 160 is pressed against the air holes 103 by the pressure of the ', keeping the The degree of vacuum inside the container 300 allows the articles contained in the container 300 to extend their shelf life. In addition, after the pumping, the second sealing ring 220 may be deflated due to deformation between the convex ring portion 130 and the inner wall of the container 300. Therefore, by the design of the first sealing ring 210, the container 300 is After the vacuum is applied, the first sealing ring 210 will be more tightly pressed by the abutting portion 110 and the top edge 310 at the opening of the container 300, so the gap between the convex ring portion 130 and the inner wall of the capacitor 300, and the The precision of the overall thickness of the second seal ring 220 can be neglected, and the second seal ring 220 may be deflated after evacuation, so that the two-layer structure of the present invention can increase the ease of manufacture. As shown in Fig. 10, it is a sectional view of the combination when the present invention is released. If the cover 100 is to be opened, the pressing portion 162 of the gas-filled umbrella valve 160 is pressed, and the diaphragm 161 is deformed by the pressing of the pressing portion 162, so that the air hole 103 on the surface of the recess 101 can be separated. The outside air is smoothly introduced into the container 300, so that the cover 100 can be easily opened. In addition, in the application, when the sealing cap of the present invention is used for both large and small containers, the air in the large container can be directly sucked, so that the small container housed in the large container is also subjected to pressure change. The internal air is released into a large container, and then the inside of the large container is evacuated, so that the containers of the inner and outer devices can reach a vacuum state. However, the above is only a preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent change of the scope and the description of the invention according to the invention 13200900330 Modifications are still within the scope of the invention patent. / 14 200900330 [Simple description of the drawings] Fig. 1 is a schematic exploded view of a conventional sealing cover and a container.
