This funnel is quite useful for refilling under-sink hand soap pump bottles. Simply get a second bottle of about the same size as the under-sink bottle, fill it up, remove the pump head and insert the funnel, then place the second bottle into the funnel. The funnel design has ribs on the inside and outside to allow for air into the draining bottle and to escape from the under-sink bottle. No more mess or over-filling!

Parameterized Fusion360 model included.
