In the USA they are common in micro brew restaurants.

The are called "growlers."

It is for taking the local brewed tap beer home and may be refilled multiple times.

Third generation home brewer - before the "Real Ale Societies "homebrew was the only way to get real beer over here. With growlers now so common - my stready stream of 50 years - is diminished.
