ABSTRACT:
A container for free-flowing, fluid and like materials, comprising a tubular outer envelope (1; 4; 7; 13; 17) that can be closed at both ends and a tubular inner member (2; 5; 8; 14; 18) which at at least four positions spaced about the circumference of the tubular outer envelope is connected to said outer envelope, said inner member having a length that is 30-100% of the height of the container. Said container further comprises stiffening means (3; 6; 10; 15; 19) extending throughout the entire height of the container, having a relatively high stiffness or tear resistance of their own, and extending substantially in contact with the inner member. Said stiffening means can be a tube (3; 6) telescoped within the inner member or substantially rigid stiffening members (10; 15; 19) inserted into pockets formed adjacent a joint (9) between the outer envelope and the inner member and extending lengthwise of the container.
