Coffin case is a common name for open refrigerated or frozen food display cases where product is stacked, rather than displayed on shelves. I have never heard them refered to as “coffins”, but rather as “coffin cases”. They resemble coffins without lids, but are obviously, wider and longer than the typical coffin. Another name is “well cases”. Coffin cases are usually open (the cold air stays low enough in the case to keep product cold or frozen). Upright cases, those with shelves, can also be open, but for the last 20 years have mostly been built with self closing doors. I am surprised that this term has never been published. Perhaps it has only appeared in industry journals.
