What is the method to prevent canned chili from opening

When the canned chili cannot be opened, you can try soaking it in hot water, using rubber gloves to prevent slipping, tapping the edge of the bottle cap, using tools to pry open or replacing the can opener, and other methods.

1. Hot water soaking

Invert the can and soak it in hot water for a few minutes. The principle of thermal expansion and contraction will cause the metal bottle cap to loosen. Pay attention to the water level not exceeding the seam between the bottle cap and the bottle body to avoid water infiltration and affecting food quality. This method is suitable for canned goods in glass bottles, and plastic materials should be used with caution.

2. Anti slip rubber gloves

Wear rubber gloves to increase friction, grip the bottle tightly with your left hand, and rotate the bottle cap counterclockwise with your right hand. Rubber material can effectively solve the problem of slipping hands, especially suitable for cans with residual oil stains. If it still cannot be opened, you can use a towel to wrap the bottle cap to enhance the force.

3. Tap the edge of the bottle cap

Use a metal spoon handle to evenly tap along the side of the bottle cap once, breaking the vacuum seal state. Keep the can stable when tapping, with moderate force to avoid deformation. This method has a significant effect on unopened vacuum packaged cans, and can usually be easily unscrewed after operation.

4. Tool pry open

Use a butter knife or flat head screwdriver to insert into the groove of the bottle cap, gently pry up to release internal pressure. Pay attention to the tool and bottle cap forming a 45 degree angle to avoid scratching the sealing ring. Metal cans are suitable for this method, and sharp tools should be prevented from slipping and injuring hands during operation.

5. Replace the can opener

Choose a professional can opener with anti slip design, clamp the bottle cap and rotate the handle. Electric can openers are more suitable for people with less strength, and manual styles should pay attention to selecting the appropriate bayonet for the size of the can. It is recommended to equip canned food with specialized tools for long-term use.

Patience should be maintained when handling stubborn cans to avoid violent opening that may cause glass splashing or metal cuts. Canned food should be stored in a cool and dry place for daily use, and the packaging should be checked regularly for expansion and deformation. If multiple methods still fail to open, the can can can be heated as a whole and quickly cooled to use a larger temperature difference to help loosen. For cans with severe corrosion or obvious deterioration, it is recommended to discard them directly to ensure food safety.
