description The utility model relates to a sealing case, comprising a case body and a cover body which cover with each other, a sealing loop which is nipped between the case body and the periphery of the cover body and a sealing device which is combined on the cover body. The sealing device comprises a sealing loop which is covered at the top part of the cover body; a movable cover which is provided at the top part of the cover body via a pivot; a sealing sheet which is covered at the middle of the movable cover and a cover loop which is pressed outside the sealing sheet and combined on the movable cover. When food is arranged into the case body, a part of the air in the case can be discharged by pressing the cover body. The case body and the cover body can be combined tightly under the influence of the atmospheric pressure. The sealing sheet is sealed closely with the sealing loop to prevent the inleakage of the air. When the sealing case is to be opened, the sealing device is pulled up and the outside air can leak into the case body. The pressure in the sealing case and outside the sealing case can get to a balance, so the cover body is opened.
