[ technical field ] A method for producing a semiconductor device

The invention relates to a container sealing cover, in particular to an automatic opening and closing sealing cover.

[ background of the invention ]

At present, in the use process of the container with the cover on the market, if a user forgets or does not close the cover in time, winged insects, flies, dust or water vapor are likely to enter the container, substances contained in the container are likely to be polluted and deteriorate, the container is not only insanitary, but also has great hidden danger to the health of people, and therefore the problem is solved by the rotatable cover on the market.

However, before/after the use or the use, the rotating cover has a problem that the rotating cover cannot be fixed, so that the opening of the container is easy to open, and further, the substance in the inner cavity of the container is easy to spill and flow out, thereby causing resource waste and inconvenience for people's life, for example: when the container is inclined by being accidentally collided, the cover cannot be fixed, so that the substance in the container is scattered and flows out.

Therefore, the invention is researched and proposed aiming at the defects of the prior art.
