What is the purpose of the ridges that prevent the funnel form fitting tightly in the mouth of a bottle?

When you put water into the bottle, you have to let that same volume of air escape. If the funnel were a tight fit, that air would have to come up the tube of the funnel, disrupting the flow of the liquid. The result would be erratic water flow, sort of a "gurglegurgle gurgle" flow instead of a continuous flow.
