I figured this out once myself. I had dropped my Coke plastic cap, so to replace it I took a metal cap from a non-carbonated drink (maybe water) that was of the same size.
When I eventually opened the bottle it basically shot my hand off with some speed and shock.
I was quite surprised and then investigated and found the gaps, it's a neat little addition to the design (and makes one wonder how many other little details like this there are in daily life products that we'll never even know about).
