<p>The method of installing an alcohol beverage bag (10) into a container (12) such as a beer keg through an aperture (46) in the container has the steps of folding the bag into overlapping panels so as to have a cross-sectional area able to pass through the aperture of the container and then inserting the folded bag through the aperture and into the container. The beverage bag comprises first (14) and second (16) rectangular panels having peripheral edges (22) welded together to form a first seam (18). Each panel has an area larger than a cross-sectional area for the keg and the panels are sized relative to the keg cross-sectional area to permit the panels to be forced apart during bag filling so as to expand bag internal space to approximate the volume of the keg. The bag has an open neck (30) member passing through an aperture of the first panel and welded thereto to form a second seam (32). The aperture in the first panel of the bag is preferably offset from the center (26) of the panel to reduce the likelihood of the first seam of the bag being bunched together and pulled at one time through the keg aperture during bag extraction. Consequently, less stress is placed on the seams during bag extraction from the keg thereby enhancing the recycling life of the bag.</p> |
