FLEXIBLE, COLLAPSIBLE CONTAINER HAVING A STIFFENER MEMBER THEREIN

摘要

A novel flexible, collapsible container comprises a pair of facing sheet sections sealed together along most of the periphery thereof. A stiffener bar section is positioned transversely adjacent one end of the container between the facing sheet sections. Seal lines between the sheet sections on each side of, adjacent to, and parallel to the stiffener bar section in the container isolate and retain the stiffener bar section, which is of less width than the container in its as-made configuration. The stiffener bar section facilitates the flat collapse of the container by holding the tall end of the container in a linear configuration and promotes the accurate reading of volume graduations.
