A free-standing container for containing fluids is comprised of flexibly foldable walls and comprises a top configuration similar to that of a pillow pack. The container comprises wall stiffening means 11, 31 attached to its wall exterior. The container may also comprise a user grip and a fluid valve attached, diagonally across a top corner, to the outside of the container wall. The user grip is formed as a longitudinal relatively stiff member that is oriented vertically, and attached adjacent to or abutting against the container wall. The user grip 31 may be attached by overlying adhesive tape 17, 32 such that it contributes to the vertical stability of the container. The fluid valve means12 provides a user grip that enables the user to fold the container wall material and lock it in a folded position. |
