My kid likes crispy chicken sandwiches and burgers would the basic-size patties fit in there width-wise?

Thanks for the question! The interior diameter of the item is 3.875” so if the chicken & burger patties are less than that, they will fit. Arctic Zone Proucts

What is the diameter of the opening?

Thanks for your question! The diameter of the opening is approximately 3.82". Hope this helps! Arctic Zone Products

The label that came inside the container stated that it is made with stainless steel and polypropylene. It did not say BPA free.

What type of food did this keep warm for 4+ hours? Wondering if it would keep meatballs or chicken nuggets warm for my daughters lunches.

In my experience 2+ hours. I make pasta for the kid's school lunch. Before packing the lunch, I use boiling water to heat up these lunchboxes. Pasta is slightly warm after 4 hours. The lids are plastic so they lose a lot of heat. I suggest packing this lunch box in an insulated layer to extend the warmth. Overall, I am happy with the purchase.
