A corrugated bulk container for shipping, storing and dispensing liquids and semi-liquid fluids. The container is a laminated triple wall open-ended tube having side walls and end walls, and a bag assembly is supported in the tube for containing the liquid or semi-liquid fluid. The bag assembly includes a bag having a fill valve and a dispensing valve attached to it, a bag cassette to which a bottom end of the bag is attached, and a fill valve support plate to which a top end of the bag is attached. The bag cassette has structure to receive and hold the dispensing valve in position relative to a dispensing valve opening in the tube, and the fill valve support plate has structure to receive and support the fill valve. The container is attached to a pallet by severable structure, and the fill valve support plate is attached to the tube by severable structure so that the bag assembly can be removed from the container, for easy collapse of the container for disposal or recycling. Fill valve support structure is cut from the fill valve support plate and folded into a position to receive and support the fill valve.

A bulk container as claimed in claim 12, wherein: an opening is formed through the support panel, and the fill valve is received in the opening and supported by the support panel and support arms. 14. A bulk container as claimed in claim 13, wherein: a separate locking panel is lodged against the support panel and wedged between the support arms, said locking panel having an opening through which the fill valve is received. 15. A bulk container as claimed in claim 13, wherein: the support panel and support arms are formed by a first series of cuts made in the flat panel, the support panel and support arms being folded 180 degrees from the plane of the flat panel to a support position aligned with the fill valve. 16. A bulk container as claimed in claim 15, wherein: a second series of cuts are made in the flat panel spaced from the first series of cuts, said second series of cuts forming an opening having a size and shape to receive the support panel therethrough. 17. A bulk container as claimed in claim 1, wherein: the tube comprises two laminated layers of triple wall corrugated material. 18. A bulk container as claimed in claim 17, wherein: insert panels are disposed inside the tube and against at least one of the side and end walls to reinforce the walls against outward bulging and to increase stacking strength of the container. 19. The bulk container as claimed in claim 1, wherein: said severable means comprises at least one pair of flaps, each flap connected to opposite edges of said fill valve support plate and positioned to secure said fill valve support plate to an upper portion of said tube. 20. The bulk container as claimed in claim 19, wherein: said severable means further comprises at least one member selected from the group consisting of a score line, perforated line, and tear tape positioned between each opposite edge of said fill valve support plate and said flap to which each opposite edge is attached. 21.
