I don't know Jon, Maybe the pickle lift is designed like a Japanese hand fan on a pivot goes down the inside of the jar straight then once it comes in contact with the curvature at the bottom it pivots 90° and unfolds like the solar array on a satellite and locks in place by a detent . Getting it out again would require twisting it 1 direction or the other to close the fan then continue turning until you overcame the detent as you are pulling it out of the jar.
The Pringles thing would be similar except it probably would only have 1 articulation to the detent.
Just a thought,LOL.
