Consider upgrading his thermos. I recently purchased this one: https://www.amazon.com/dp/B07Z4L57XQ Gifted it to my neighbor... he raves about how good it is. 34 ounces, though smaller sizes are available. Linked is what I purchased. Insulated is the word you want. Another older double-walled thermos he had would get too hot to touch (didn't keep his coffee hot enough/long enough too, so there was that) Cool to touch. Coffee stays piping scalding steamy hot for hours! Also, cold drinks stay cold with zero sweating/condensation for the whole day. I can say without equivocation that this is a winner. The gent I gifted it too asked that I get him a spare.
