Abstract
A flexible bulkhead (36) is provided that includes a plurality of horizontal poles (38) disposed in channels (54) and (56) on opposite sides of a container (10). Webbing straps (50) and (52) are operable to space the poles (38) a predetermined distance apart when installed between hooks on either side of the container opening and at the upper and lower corners therein. When pulled taut, the webbing straps (50) and (52) maintain the material of the flexible bulkhead (36) in a taut configuration. Flaps (66) and (68) extend from the peripheral edges on the sides of the flexible bulkhead (36) and inward to the container (10). A liner (16) is then disposed in the container (10) and inflated with a vacuum system through a manifold (42) and a blower (22). The flaps (66) and (68) prevent deformation of the flexible material of the bulkhead (36) to minimize air from flowing under and around the flexible bulkhead (36).
