Abstract: An exothermic burning rod includes exothermic fuel members extending axially within an elongate, external tube. The exothermic fuel members include an essentially ferrous inner core provided with an outer aluminum coating. A gas passage extends internally within the tube adjacent the exothermic fuel members.

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.

Abstract: This invention pertains to a container made of a rigid tubular conformation. Each end of the tube is flattened at a substantial central portion to produce and provide a protruding end portion, and in this flattened and sloped end or portion at least one access aperture is formed. This aperture is selectively closed by a plug, valve or cap adapted to be secured in a fluid-tight manner in this container. Usually this container is made from thermoplastic pipe or tubing from three inches to more than two feet in diameter. The ends are sealed to prevent contamination or ingress of water and the like. The ends are sealed to keep contents from getting out. Hand holds may be formed where the ends are sealed. This tubular container is made with a small amount of tooling and minimum skills by the fabricator. These containers can and may be made economically with very short-run processes, and size extent and length may be changed easily.
