As shown in FIGS. 1, 2, 5 and 6, the intake air from the accommodating space 12 driven by the pressure difference between the tray inside space 222 and the accommodating space 12 flows through the guiding grooves 225, the flowing clearance and the temporary chamber and pushes the membrane 44A away from the bottom inner surface of the spacer tray 22 to open the tray one-way exhaust passage so that the intake air can flow to the tray inside space 222. After the intake air flows through the membrane 44A, the membrane 44A recovers to have an airtight contact with the bottom inner surface of the spacer tray 22 to block the intake air from flowing back to the accommodating space 12.

Furthermore, as shown FIGS. 1 to 4, according to the vacuum container 100 of the embodiment of the present invention, the top cap 3 has a plurality of exhausting grooves 33. The exhausting grooves 33 are recessed from a bottom surface of the top cap 3 in a radially spaced manner around the exhausting hole 32.

The membrane 44B extends downward from a rim of the top cover part 43B in an inclined angle with respect to the top cover part 43B, and is in airtight contact with a top surface of the top cap 3, thereby forming, together with the top cap 3 and the top cover part 43B, a temporary chamber communicating with the flowing clearance.

As shown FIGS. 1 to 4, the exhaust air from the tray inside space 222 compressed by the pressing part 31 of the top cap 3 flows through the exhausting grooves 33, the flowing clearance and the temporary chamber and pushes the membrane 44B away from the top surface of the top cap 3 to open the cap one-way exhaust passage so that the exhaust air can flow to the outside space. After the exhaust air flows through the membrane 44B, the membrane 44B recovers to have an airtight contact with the top surface of the top cap 3 to block the outside air flowing back to the tray inside space 222.

After releasing the pressing operation of the pressing part 31, the vent hole 35 is open and the tray inside space 222 will have an atmospheric pressure the same as the outside space.

The vacuum container 100 of the embodiment of the present invention only comprises the storage container 1, the connecting tray component 2, the top cap 3 and the two one-way exhausters 4A, 4B such that the overall assembly structure of the vacuum container 100 is relative simple, and thus easy to disassemble and assemble, which is conducive to cleaning of the vacuum container 100.

Furthermore, by pressing the pressing part 31 of the top cap 3, the exhaust air from the tray inside space 222 is exhausted through the cap one-way exhaust passage to the outside space, the intake air from the accommodating space 12 flows through the tray one-way exhaust passage to the tray inside space 222, and therefore the accommodating space 12 of the storage container 1 becomes in the state approaching vacuum. In detail, the vacuum state of the accommodating space 12 can be released simply by holding the holding tab 212 to pull the connecting ring 21 away from the top portion of the storage container 1 to flow the outside air into the accommodating space 12.

The vacuum container as claimed in claim 2, wherein the spacer tray of the connection tray component has a plurality of guiding grooves, the guiding grooves are recessed from a bottom outer surface of the spacer tray in a radially spaced manner around the guiding hole, the guiding grooves communicate with the accommodating space of the storage container, the one-way exhauster mounted in the spacer tray has a cylinder, a bottom contact block, a top cover part and a membrane,the cylinder is inserted in the guiding hole of the spacer tray, a flowing clearance is formed between an outer surface of the cylinder and the bottom base of the spacer tray, and the flowing clearance communicates with the guiding grooves,the bottom contact block is arranged at a bottom portion of the cylinder and in contact with the bottom outer surface of the spacer tray to cover the guiding grooves,the top cover part is arranged at a top portion of the cylinder and disposed in the tray inside space of the spacer tray,the membrane is formed extending downward from a rim of the top cover part and at an inclined angle to the top cover part, and is in airtight contact with a bottom inner surface of the spacer tray, thereby forming, together with the spacer tray and the top cover part, a temporary chamber communicating with the flowing clearance,wherein the intake air from the accommodating space driven by the pressure difference between the tray inside space and the accommodating space flows through the guiding grooves, the flowing clearance and the temporary chamber and pushes the membrane away from the bottom inner surface of the spacer tray to open the tray one-way exhaust passage to flow the air to the tray inside space,after the intake air flows through the membrane, the membrane recovers to have an airtight contact with the bottom inner surface of the spacer tray to block the intake air from flowing back to the accommodating space.

7. The vacuum container as claimed in claim 2, wherein the top cap has a plurality of exhausting grooves, the exhausting grooves are recessed from a bottom surface of the top cap in a radially spaced manner around the exhausting hole, the exhausting grooves communicate with the tray inside space of the spacer tray, the one-way exhauster mounted in the top cap has a cylinder, a bottom contact block, a top cover part and a membrane,the cylinder is inserted in the exhausting hole of the top cap, a flowing clearance is formed between an outer surface of the cylinder and the top cap, and the flowing clearance communicates with the exhausting grooves,the bottom contact block is arranged at a bottom portion of the cylinder and in contact with the bottom surface of the top cap to cover the exhausting grooves,the top cover part is arranged at a top portion of the cylinder and disposed between the exhausting hole and the outside space,the membrane extends downward from a rim of the top cover part in an inclined angle with respect to the top cover part, and is in airtight contact with a top surface of the top cap, and the membrane is together with the top cap and the top cover part to form a temporary chamber communicating with the flowing clearance,wherein the exhaust air from the tray inside space compressed by the pressing part of the top cap flows through the exhausting grooves, the flowing clearance and the temporary chamber and pushes the membrane away from the top surface of the top cap to open the cap one-way exhaust passage to flow the air to the outside space,after the exhaust air flows through the membrane, the membrane recovers to have an airtight contact with the top surface of the top cap to block the outside air flowing back to the tray inside space.

8. The vacuum container as claimed in claim 1, wherein the top cap further has a spacer groove, the spacer groove is recessed in the top cap and is formed to surround, together with the exhausting hole, the pressing part so that the pressing part of the top cap is easy to collapse and deform by pressing the pressing part.

9. The vacuum container as claimed in claim 1, wherein the top cap has a vent hole, the vent hole is formed through the top cap and located in the pressing part, the vent hole communicates with the outside space and the tray inside space, wherein by pressing the top cap while blocking the vent hole, the top cap collapses to deform so as to exhaust the exhaust air to the outside space by compression of the tray inside space,after releasing the pressing operation of the pressing part, the vent hole is open and the tray inside space will have an atmospheric pressure same as the outside space.
