Okay, it's really not that complicated. A big steel pedal can with two pedals, One in front that opens the lid, and another on the side that opens a one-way valve for ten seconds.

A similar but more low-tech version has a one-way valve near the bottom that lets air in but wont let any nasty liquid out. This could be sold as a make-your-own version that is just the threaded valve and a couple of washers and a couple of nuts.

We've done this before. I think the final verdict was to run a tube to the top of the can for passive ventilation both during insertion as well as removal.
