Beschreibung
Zusammenfassung:	The utility model belongs to a packaging container, particularly a wine barrel which can isolate air and press wine out. An airbag is arranged in the wine barrel which is composed of a barrel body and a barrel cover, a charging connector which has a one-way stop valve is arranged on one side of the barrel body, an elastic inner liner is arranged in the airbag, and the pipe joint of the wine barrel is connected with the wine outlet valve which is on the other side of the barrel body by passing through the airbag and through a locking nut. The utility model has the obvious advantages of simple structure and convenient use and can fully keep the quality of bulk wine so that the wine barrel can become a reliable flow container for the marketing retail of wine.
