Hydrogen peroxide + baking soda = ????

Following what appear to be standard instructions on how to clean the coffee stains from a stainless steel thermos, I mixed a cup of hydrogen peroxide and a few tblsp baking soda. Then screwed on the plastic cap, shook a few times and went away for half hour. Releasing the cap resulted in a pressurized spray.
This must be a pretty simple reaction, but my knowledge of chemistry is ancient.
What's causing the pressure ?
