How very kind of you Steve to post your suggestion, I'll look out for something similar. I always keep 'easy' lids and closures, because often things are standard sizes. I have a good one for my bleach containers. My husband takes off the press-and-twist thing and I put on the easy lid. Even using pliers to get stuff open isn't possible for me as I can't manipulate them. My good friend does voluntary work for AgeUK, and she knows of lots of aids and gadgets, so maybe next time I'm sitting in her kitchen munching on her chocolate clairs, I'll ask her for some suggestions!
