Growlers
From Beeripedia the Beer Wiki
Tin Pail Growlers.
A container, such as a pail or pitcher, that is used for carrying beer.
This is from Modern Drunkard magazine:
Growler: The refillable glass jugs you’re allowed to walk out of microbreweries with were once metal buckets. In pre-Prohibition times it was common for fathers to dispatch their progeny to the saloon with a growler to collect beer, and it was probably named for the growling sound a metal bucket full of beer makes when pushed across a bar top. The once popular term rushing the growler meant a hurried beer run—beer in a bucket tends to lose its head rather quickly and dad probably preferred it didn’t.
