Abstract

Abstract To prevent a bag-in-box type of container comprising a box (10) enclosing a flexible bag (22) from sagging, bulging or leaking when the bag (22) is filled with a pressurized liquid, such as carbonated beverage, the bag (22) is located inside the tube or sleeve (15). Transverse platforms (16, 17) with flanges directed towards respective ends of the box (10) are arranged at each end of the tube or sleeve (15) when the latter is formed of rigid or inelastic material, to transmit pressure from the tube or sleeve (15) to the box. When the tube or sleeve is formed of elastic material such platforms (16,17) are not required, but the slotted platform (17) is usually retained for location of the tap (26) and the bag (22).
