Properly adjusted, they will open just fine with a finger tip.
Make sure your O rings are in good shape and can slide easy on the taper as the cap tab is open and closed. If you can't open it with a finger tip, it is adjusted too tight or (and) the O ring is not sliding as it expands when you flip the tab down.
Adjusted too tight will cause extra strain on the hinge pin and it will fail.
