When opening the oil, it is normal to remove a piece that is inside the cap in order to open it and use the oil.
However, be aware that you should never throw away the part you have removed, because it has a very important function.
Let’s find out what this part of the cap is for.
Oil
Few people know what the piece inside the lid of regular oil bottles is for, and most have the habit of throwing it away immediately after removing it.
The piece we are talking about is the one found once the lid is removed, and it consists of a small ring that completely closes the bottle.
Typically, we have the habit of pulling the ring and throwing that component in the trash, and as many others do, I’m sure you’ve done it many times too.
This is absolutely incorrect, because the purpose of this part of the cap is completely ingenious and it is good to highlight it, so that everyone can become aware of it.
Let’s see below what the part of the cap located below is used for once the bottle of oil is opened.
