WHAT IS CLAIMED IS

1. A cap closing structure for a sealed container, comprising:

an upper cover comprising a top plate and a circumferential bracket extended from the top plate, the top plate having a through hole formed thereon, the circumferential bracket having a retaining slanted surface formed thereon;

a lower cover arranged underneath the upper cover, the lower cover comprising a base plate and a sealing ring connected to the base plate, the base plate having a latch member extended to penetrate into the through hole, the latch member having a guiding structure formed thereon, the sealing ring having one end formed at another side of the retaining slanted surface;

an elastic element mounted onto an outer perimeter of the latch member and elastically clamped between the top plate and the bottom plate; and

a handle member comprising a dial lever and an arm extended from the dial lever, the arm connected to a shaft, the shaft configured to operably move inside the guiding structure, thereby allowing the sealing ring to be tightly sealed between the retaining slanted surface and the container.

2. The cap closing structure for a sealed container, according to Claim 1, wherein the through hole includes a circumferential wall extended from a perimeter thereof, and the outer perimeter of the latch member is configured to be surrounded by the circumferential wall.

3. The cap closing structure for a sealed container, according to Claim 2, wherein an upper mounting ring is configured to extend between the circumferential wall and the circumferential bracket; a separation distance between the upper mounting ring and the circumferential bracket is smaller than a separation distance between the upper mounting ring and a central line of the top plate.

4. The cap closing structure for a sealed container, according to Claim 2, wherein an upper mounting ring is configured to extend between the circumferential wall and the

circumferential bracket; a lower mounting ring is configured to extend on the base plate at a location corresponding to the upper mounting ring; the lower mounting ring and the upper mounting ring are mounted onto each other.

5. The cap closing structure for a sealed container, according to Claim 4, wherein the upper mounting ring includes a plurality of elastic hooks, the lower mounting rings includes a plurality of locking slots, and each one of the elastic hooks is locked onto each one of the locking slots correspondingly.

6. The cap closing structure for a sealed container, according to Claim 4, wherein a plurality of ribs are formed between an outer perimeter of the lower mounting ring and the base plate.

7. The cap closing structure for a sealed container, according to Claim 1, wherein the guiding structure comprises a first channel and a second channel fluidly connected to the first channel.

8. The cap closing structure for a sealed container, according to Claim 1, wherein the sealing ring comprises a connecting section and a compressive deformation section extended from the connecting section; the connecting section is configured to firmly attach onto a perimeter of the base plate; the compressive deformation section is configured to extend toward a direction of the upper cover and formed at an outer side of the retaining slanted surface.

9. The cap closing structure for a sealed container, according to Claim 1, wherein the base plate and the sealing ring are integrally formed as one single piece via an injection molding formation method; the arm and the dial lever are also integrally formed as one single piece via an injection molding formation method.

10. The cap closing structure for a sealed container, according to Claim 1, wherein the arm and the shaft are of a quantity of two; the guiding structure comprises a pair of first guiding channels and a second guiding channel fluidly connected to each one of the first guiding channels respectively; each one of the shafts of each one of the arms is arranged corresponding to each one

of the first guiding channels and each one of the second guiding channels respectively.
