A flexible bag-like liner having a relatively thin wall is adapted to be connected to a wall portion of a receptacle with a liquid passageway provided in association with the wall portion so that liquid may be introduced into the liner and discharged therefrom; the wall portion is adapted to be fitted substantially in sealing relationship with a body portion of the receptacle with discharge means being provided for discharging air from between the liner and the interior walls of the receptacle when fluid under pressure is introduced into the liner to urge the liner against the interior walls of the receptacle. The arrangement is such that when the contents of the liner are partially discharged, a partial vacuum between the exterior of the liner and the interior of the receptacle urges the liner into contact with interior walls of the receptacle.
