1, first check whether the method of screwing the bottle cap is correct. The left side is loose and the right side is tight. The general design is right-handed, counterclockwise. If you twist it in the wrong direction, it will only get tighter and tighter, and it will definitely not open.

You can try soaking the lid in hot water first. If it is not very tight, you can usually soak it in hot water and then twist it to unscrew it. If not, use a hair dryer.

3. Because the oil pot is slippery, wrap the oil pot glass pot with a towel, hold the bottle steady and break it carefully. Blow it with a blower at the position where the cover is screwed with the screw mouth of the glass bottle body. Don't get too close, lest you burn the plastic. If you think the plastic is a little hot, stop and try to twist it. In this way, it can be opened.
