When the lid of a glass bottle cannot be unscrewed, you can try the following methods:
Hot water immersion method: Turn the glass bottle upside down and immerse the lid partly in hot water, and let it stand for 1-2 minutes. Hot water will expand the lid, thereby reducing the friction between the lid and the bottle mouth, making it easier to open.
Tap the lid: Tap the edge of the lid with a spoon or the back of a knife to balance the internal air pressure, making it easier to unscrew. This method is suitable for situations where the lid is difficult to open due to air pressure difference.
Inverted relaxation: Turn the bottle upside down for a while to allow the internal air to circulate, and then try to unscrew it. This method uses the principle of air pressure balance.
Wrap and unscrew: Wrap the lid with a paper towel or rag to increase friction, and then try to unscrew it. This method is suitable for situations where your hands slip or the friction is insufficient.
Use lubricant: Apply cooking oil or olive oil to the threads of the lid to reduce friction and make it easier to unscrew the lid. Be sure to clean the cup after use to avoid oil residue.
Freezing method: Put the bottle in the freezer of the refrigerator. The inside of the glass bottle will shrink at low temperatures, and the contact surface between the lid and the bottle mouth will loosen, making it easier to open. This method is suitable for situations where it is difficult to open due to tight sealing.
Use tools: Tools such as bottle openers and carp pliers can help pry open the bottle cap. Be careful not to damage the bottle or lid when using it.
