Abstract (en)
[origin: EP0372173A2] A flexible lining in the form of a bag or sack for vats, drums and like hard packagings with round or rounded bottoms is formed from a bag tube (2;2';2'') with a round bottom (1;1') corresponding to the bottom of the hard packaging at one of its two ends. The round bottom (1;1') has the basic shape of a cross- bottom with two corner tucks (8, 9) lying opposite one another, which start, with their diagonal fold edges (10,11), from the original lateral fold edges (3, 4), which lie opposite one another, of the laid-flat bag tube (2;2';2'') and which are interconnected, by means of a flat material connection, at their transverse edges (12) which face one another and in each case extend between their diagonal fold edges (10,11). The diagonal fold edges (10,11) of the corner tucks (8,9), which in each case lie opposite one another on both sides of the central transverse plane of the round bottom (1;1'), are respectively interconnected, by means of a curved outwardly-arched seam (15;28) connecting the round bottom (1;1') to the adjoining flat wall (5) of the bag tube (2;2';2''), which in each case extends between the lateral fold edges (3,4) of the bag tube. <IMAGE>
