An inflatable self-supporting bag formed from a single sheet of flexible air impervious material and having a single ply lower portion defining a bottom wall and a lower portion of a bag side wall and an inflatable upper portion formed by two plies including an inner ply and an outer ply defining an air chamber therebetween. The inner and outer plies are connected together in face-to-face relation along a plurality of spaced apart lines of attachment which divide the air chamber into a plurality of intercommunicating sections which impart a generally cylindrical shape to the upper portion of the bag when it is inflated. A tubular inflating member having an associated removable plug is provided for inflating the upper portion of the bag.

A collapsed inflatable self-supporting bag comprising a substantially flat generally rectangular structure defined by a plurality of generally rectangular sheet material panels, each of said panels being connected in face-to-face relation to another of said panels, said structure having a lower portion formed from a single ply of sheet material and including two substantially rectangular panels connected together in face-to-face relation along bottom and side marginal edge portions thereof defining a bag bottom and a portion of a bag sidewall, and an inflatable upper portion contiguous to said lower portion and formed by a plurality of generally rectangular air impervious sheet material panels defining two plies including an inner ply and an outer ply, said upper portion defining the remaining portion of said sidewall and a mouth opening at the upper end thereof, said inner ply and said outer ply cooperating to define an air chamber therebetween, connecting means for attaching said inner ply and said outer ply in face-to-face relation to each other along generally parallel lines of attachment to divide said chamber into a plurality of intercommunicating sections inflating means for introducing air into said chamber to inflate said upper portion, said upper portion in its inflated condition having a generally cylindrical configuration being defined by a plurality of intercommunicating elongate tubular portions immediately adjacent to each other and extending in parallel relation to the central axis of said upper portion, said lower portion depending from said upper portion, and closure means for releasably retaining said upper portion in inflated condition.
