ABSTRACT:
The disclosed container for fluids has a pouring spout, the periphery of the container when empty and flat being defined essentially by straight side margins, and top and bottom margins that are curved inward and outward, respectively. A series of containers, formed of strip material, makes efficient use of the strip material by avoiding waste and by realizing a remarkably high ratio of container volume to area of wall material. The disclosed containers have a hang-up tab at the upper end of the container remote from the spout, the container being proportioned to avoid spilling of contents from the spout when the container is suspended by its hang-up tab.
