Gents,
I have found that my cap is also very hard to get off, however my main issue I think is not a strength problem but a grip problem and you thumb and index finger slipping off the chrome finish. What I have done to overcome this and works perfectly everytime not matter how many times I turn it to close it, is that I have cut a piece of rubber out of a dish washing glove that simply covers the cap and allows to grip the thing properly. I just keep this piece of rubber in my jacket pocket so it is no drama and doesn't get in the way and i don't forget it.
Give it a try it will work a treat, let me know how you go.
