The porta potty is a great invention that has saved most of us a time or two. However, it can be our worst nightmare in some cases. Whether it be an extra high wind, something heavy bumping the wrong way or a cruel prank, a porta potty can tip over and the hapless individual inside is in for a nasty treat -- especially if the porta potty lands door-down. To remedy these unfortunate situations, I have devised two improvements to the standard porta potty design. The Escape Hatch and the Pressure Latch.
The Escape Hatch is implemented with a removable roof. Regardless of which side the porta potty lands on in a fall, the victim can crawl to the top where a well-marked ceiling can be easily removed. The person can then crawl out to freedom.
"But wait!" you say, "The person will still get covered in human waste and chemical!" This is where the Pressure Latch comes in.
The bowl of the toilet will have a half-sphere cover that is by default closed. When a person enters the porta potty, their weight (whether standing or sitting) will open this latch by triggering a quarter rotation of the cover, thus opening the toilet bowl. If the porta potty were to tip over, the person's weight would leave the trigger areas and the latch would shut, stopping any matter from leaving the container and drenching the person. This device would also help greatly to prevent odor emanating from the bowl when the porta potty is unoccupied.
