It was actually a trademarked name for the original trash-collection containers made by Dempster Brothers, a US company (still around), back in 1936. It has since entered the American-English language and is very-well known in the US but is still not very well known in other countries.
Pictured are dumpsters from an Eskimo village that are painted with community values (see the link).
What? How? Wonder.
