A collapsible container closed but for an opening from an outlet end and having at the other base end, a three dimensional structure formed by a bottom wall, a central portion and peripheral edge portions which are sufficiently strong to resist deflection and maintain support portions of the base end in desired positions, preferably disposed i n a flat plane both while a container is full and while in a collapsed or uncollapsed condition of the container. Preferably, the base has the support portions disposed in a flat plane norma l to a longitudinal of the container and will support the container on a horizontal support surface with a longitudinal of the container to extend vertically upwardly therefrom, preferably, in all collapsed and uncollapsed conditions of the container.
