Squared Funnel / Funnel

Squared Funnel
Squared Funnel

The squared funnel create space between it and a bottle, so the air can flow through this space. As a result, the air in the bottle and out the bottle has the same pressure. If you want to use a round funnel to pour liquid into a bottle more quickly ,you should raise in order to make some air flow into the bottle, but you need not to do this if you use a squared funnel. Besides ,the squared funnel has an advantage over the round one , the round is easy to roll if we put it on the desk ,but the squared one can't. This is because they have different space touch to the desktop.
