Why do not they open?

Screw reusable twist-off covers are very convenient for canning. Their operating principle is simple enough:

The reasons that a can is difficult to open can be as follows:

• Slippery surface of jar or hands;
• The lid is stuck - this happens with preservation with jam or honey;
• The pressure inside is below atmospheric, which is why the lid was drawn in more than necessary.

Important! It is necessary to know in which direction the lid is rotating - it closes clockwise, and opens - in the opposite direction.
