Description

Technical Field

[0001] The utility model relates to the technical field of vacuum devices, in particular to a Mason jar vacuum device with non-destructive cover opening. Background Art

[0002] A Mason jar, also known as a Mason jar, is a sealed glass container used for storing and pickling various foods. The container has excellent sealing performance and includes a bottle body and a tinplate bottle cap. The bottle mouth of the bottle body is provided with a thread. The tinplate bottle cap includes a circular top cover and an annular cover ring. The bottom surface of the top cover is provided with a sealing ring. When vacuuming, the top cover is buckled at the bottle mouth of the bottle body. A vacuum chamber is provided at one end of the Mason jar vacuum device. The Mason jar vacuum device is sleeved at the bottle mouth so that the bottle body is connected to the vacuum chamber. The other end of the Mason jar vacuum device is connected to a vacuum sealer. The vacuum chamber is evacuated by the vacuum sealer to generate a pressure difference. The top cover is deformed under the action of the pressure difference, so that a gap is generated between the sealing ring and the bottle mouth, and the air in the bottle body is extracted from the gap. When the preset vacuum degree is reached, the top cover is restored and re-adsorbed at the bottle mouth through the negative pressure in the bottle body, and the sealing is completed through the sealing ring. Finally, the cover ring is tightened to fix the top cover, and the vacuuming is completed. When opening the lid, the lid ring is first rotated and removed, and then the lid ring is lifted up with the help of a tool to complete the opening of the lid.
