The pail of beer to take home was also referred to as "a growler". AS in the song:

There was a little man
And he had a little can,
And he used to rush the growler!
He went in a saloon
On a Saturday afternoon,
And you oughta heard the bartender holler:

CHO:
No more beer, no more beer,
No more beer on ---- Sun-day!
No more beer, no more beer,
Gotta gitcher can till Monday!

A lot of brew pubs these days will sell growlers to take home.
