Kleenex and friends

In English, as in Spanish, the names of some brands have become the generic word for that object. The most common example is probably Kleenex. I bet you say, "Have you got a kleenex?" far more often than you would say, "Have you got a tissue?"

Other examples include Rollerblade, Jacuzzi, Frisbee, Band-aid (AmEng for 'plaster'), Linoleum, Scotch tape (AmEng) / Sellotape (BrEng), Q-tips (generally AmEng for 'cotton buds'), Thermos, Escalator and Coke. Sometimes these words even become verbs, such as with Xerox (to photocopy) and Hoover (used in British English to mean 'to vacuum').
