Funnel

Pipe with a wide top and narrow bottom

Funnel
A funnel is a tube or pipe that is wide at the top and narrow at the bottom, used for guiding liquid or powder into a small opening. Funnels are usually made of stainless steel, aluminium, glass, or plastic. The material used in its construction should be sturdy enough to withstand the weight of the substance being transferred, and it should not react with the substance. For this reason, stainless steel or glass are useful in transferring Diesel fuel, while plastic funnels are useful in the kitchen. https://en.wikipedia.org/wiki/Funnel
