When pouring thicker viscosity liquids the simple funnel tends to clog by the process that I will define as being "Hydraulic Corking!"
The most practical type of application to incorporate directly in the funnel would be a inherent tube that runs on the outside of it. Thereby allowing air to escape as thick liquids are poured in and therefore lessening the instance of hydraulic corking. Other funnel types might include those that include a Coriolis spiral on the top of the funnel and a computer engineered taper to the funnel.
There is no reason that a funnel has to be dimensionally round at the taper, perhaps a distortion might lessen the effect of hydraulic corking or gravity mass cohesion of the liquid. And indeed I am borrowing on astrophysics for that last idea.
Such applications also might help aid liquid transportation industries such as pipelines prevent terminal pressure issues or create them.
I have not tried it yet, but the most simple solution might be to insert a straw with a bent top to it in the funnel!
