but you don't put a container of acid between your legs because it's well understood that it's dangerous. There are personal responsibilities in life which means by the time you are a certain age you should know that coffee is very hot and should be treated with respect. By your argument if somone buys a lighter and accidentally sets fire to their clothes then it's the lighter manufaturer's fault.
she took the lid off the coffee and put it between her legs, she was just stupid and it was unfortunate for her but she definitely used it in a way that was clearly dangerous to the majority of people.

Well to a point a agree.
However knowingly providing a product that can / will cause 3rd degree burns warrants special understanding of product continent and delivery.

A Styrofoam cup with a cheesy fitting lit seams a bit lacking.

A stronger containment system to prevent the lid from easily coming off seems like a step in the right direction.

If I was in a lab had had to transport some acid would I use a cheep container that would allow a possible accident if dropped or tipped over or would I desire to solid container / lid system?

I get it it's just coffee and we handle it every day and are aware of its danger. But we don't handle 190 degree coffee every day. Only and McDonalds

I can see the pot spoon thing not working too well as liquids on the spoon could run down the handle. I'd be concerned about filth being on the foil lid of the apple sauce.

Spray cans and lids and newspaper and canvas, and skill

Nice lid ... a belated welcome to the Sift!

I use a small egg-sized frying pan and a pot lid for this. Works really well! Just gotta make sure to not leave the lid on too long.

run the lid under hot water for a minute so it expands hey presto

I just tap the lid a few times around the edge with the back of a butter-knife. Works most of the time.

wouldnt oxygen just seep in through the gap between the lid and the block?

Good thing he closed the lid

I can totally relate to stabbing the peanut butter lid with a knife like that.

Too much makeups on her eye lids!

Overboiling only happens to me when the lid is still on. If I could have the lid on and a wooden spoon across the top at the same time, that hack might be useful.

Hope you like eating entire jars of pickles now that you've put a giant gash in the lid.
