Repeated push and pull to extract the air in the sealed tank, not only because the extraction cylinder provided on the sealed tank takes up a lot of space, and if the extraction cylinder can be separated from the sealed tank, it often causes the extraction The inconvenience of collecting and taking out the cartridge, and at the same time, which cylinder is extracted as a separate component is easy to be lost, and the loss of the cylinder will make the sealed can no longer be used, which causes the structure to have many inconveniences in its composition and use. [0004] Therefore, some manufacturers have developed a sealed can, please refer to the first figure. The sealed can is mainly provided with a movable bottom plate (12) at the bottom of the container body (1 1), and a cover body is screwed on the open end (13) (099135850 Form No. 1010101 Page 3 / Total 16 Page 0992062644-0 201217231 [0005] [0007] [0007] [0008] 099135850 1 4), and the movable bottom plate (12) is embedded with a _ leakage preventing ring (15) on the circumference side, and the cover body (1 4) ) is provided at the corresponding open end (13) with an air inlet (16) for a check valve (17) to accommodate 'and a piston chamber (1 8) at an internal horizontal position for one The piston rod (19) is axially pierced; thus, the user only needs to horizontally reciprocally push and pull the piston rod (1 9), that is, the gas can be matched by the cooperation of the inlet port (16) and the check valve (17). Pumped out. However, the pumping of the sealed can only relies on a single piston chamber (i 8) horizontally disposed inside the cover body (14) and a small one-way air inlet port (16) as an internal and external gas exchange exchange. The only channel, so the amount of pumping is very limited, and the operator has to reciprocate countless back and forth, laborious and time consuming. In view of this, the inventors have been able to provide a sealing cover for the purpose of achieving better practical value by adhering to the rich experience in design, development and actual production of the relevant industries for many years. The present invention is directed to a direct-exhaust sealing cover for a sealed container which has the advantages of simple structure and rapid pumping. The straight suction sealing cover of the sealed container of the present invention is realized by the following technology: The straight suction sealing cover of the sealed container of the present invention comprises a body, a groove seat disposed along the axial direction of the body; The plug is installed in the socket; a piston is arranged in the socket and is positioned above the air plug' at its upper end and combined with an operation portion; when the pressure is applied to the piston through the holding operation portion, the form number A_1 is 4 Page / a total of 16 pages 0992062644-0 201217231, and can make the gas plug to open or close the corresponding action, the air in the sealed container will be pulled out.
