Bottle radha: It seems you answered your own

It seems you answered your own question Yes, I would say that a " bottle of milk" is a bottle that currently contains milk, while a "milk bottle " is a bottle that is intended to carry milk, whether it currently contains milk or not. Hello, everyone. I'm confused about bottled water and bottle of water. Is bottled water a kind of drinking water? So you can directly buy it from a grocery store when you feel thirsty, and when you finish drinking it, you got an empty bottle . Then you can put any water (tap water, fresh water)... I would call it a water bottle . if it keeps coffee hot, I'd call it a thermos (although it's not shaped like one). I would not call it a flask; to me a flask is a flat bottle made of glass or metal or possibly plastic that holds high-proof alcohol. Est ce que quelqu'un connait l'équivalent en français de l'expression "to be of the bottle "? Merci
