Abstract (en)
[origin: WO9204236A1] Containers and related method and apparatus are provided, the containers having peripheral wall thicknesses permitting controlled collapse to a compact configuration. The containers are sufficiently strong to be self-supporting both filled and empty, and capable of stand-alone use. In collapsed and folded form, the containers have one or more folded portions (56a, 58a, 60a, 62a) concentrically adjacent one another in generally surrounding relationship to discharge opening portions (54) of the containers. The apparatus includes inner and outer, concentrically arranged and relatively movable pusher members for forming the folded portions of the container.
