ABSTRACT:
A container (20) made of a rigid tubular conformation, each end (21, 22) of which is flattened to produce and provide outwardly protruding edges (25). A transition portion (33) between the flattened end portion (22) and undeformed body portion has a sloped wall in which at least one access aperture (24) is formed. The aperture (24) is selectively closed by a plug, valve or cap adapted to be secured in a fluid-tight manner in this container (20). Hand hold apertures (e.g., 23) may be formed where the ends are sealed. Disposable or reusable bladders, bags and/or liners (58, 70) can be used with these containers, and can be extended out of the fitting (50, 72) and can be gathered together and sealed (59) to provide a sanitary and tamper-proof covering. The container (20) may be pressurized if desired. An expanding plug assembly (100) having a body (102) formed of a pair of resilient members (104, 106) separated by a thin plate or diaphragm (108) also forms a part of this invention.
