Advice on a practical household problem

What sort of glass containers have tight plastic lids please?

An old remedy is to turn the jar upside down in a few inches of very hot water.
Leave for a couple of minutes then dry the jar and lid and the lid should be easier to remove.

I believe hardware shops like Robert Dyas sell gadgets for this problem in a variety of sizes.

Sorry I have no easy answers.
If I know I am going to struggle eg if I have bought the item before, I ask the person on the till to open it for me. Then I have got to put the top back on and take it home without spilling the contents.
Sometimes I wait until my son visits, which might be a while. No good for urgent items.

My problem containers don;t have twisty lids. I have a kitchen tool for those. These are large flat lids that have a little flange on the edge, and you have to lever them off.

I keep a pair of rubber gloves for 'twisty problems' like this Caleo, doesn't help with shrink wrapped items which in my opinion are the very work of the devil
