I think everyone is aware that Velcro, Kleenex, post-it are trademarks, even though they are used for off-brand products colloquially. In Germany people also use Tempo, Tesa, Edding and so on, but most are aware that these are brand names.
But I was surprised to find out that names like escalator, cellophane, flip phone, even dry ice, trampoline, dumpster were once brand names!
