The Square Funnel is a redesign of the typical kitchen aid that is used to transfer and pour liquids in a small-mouthed bottle. A research done by the designers showed that round funnels took a longer time to drain the liquid. The square funnel increases the speed of the liquid draining into the bottle considerably and it prevents an overspill too. In layman’s terms, the physics involved allows the quadrate funnel to control the inequalities in the change of air pressure inside and outside the bottle; thus enabling a swift transfer of liquids.
Square Funnel is a 2012 red dot award: design concept winner.
