A wearable belt includes two or more pressure packs, each including a pressure vessel for storing therein a fluid under pressure for providing a portable, and ambulatory, source of the compressed fluid. The pressure vessel is formed from a plurality of hollow chamber having either en ellipsoidal or spherical shape and interconnected by a plurality of relatively narrow conduit sections disposed between consecutive ones of the chambers. The pressure vessel includes a reinforcing filament wrapped around the interconnected chambers and interconnecting conduit sections to limit radial expansion of the chambers and conduit sections when filled with a fluid under pressure. The container system further includes a fluid transfer control system attached to the pressure vessel for controlling fluid flow into and out of the pressure vessel and a gas delivery mechanism for delivering gas from the pressure vessel to a user in a breathable manner. The pressure vessel is incorporated into the belt as two or more interconnected packs. Each pack comprises a plurality of interconnected chambers encased in a relatively rigid padded foam housing. A connecting conduit between adjacent packs is disposed within a flexible joint that can be bent or twisted, and belt straps are connected to the endmost pack housings. The belt straps include mating halves of a buckle, or other connecting feature, so that the belt can be secured around the torso of a person. The flexible joint located between adjacent relatively rigid packs permits the overall belt to conform to the body of the wearer, thereby increasing comfort and reducing the bulk created by the belt.

The barbecue grill assembly as claimed in claim 2, wherein said surrounding wall of said casing includes a main portion and front and rear support plates, each of which has a hinge end hinged to said main portion of said surrounding wall and a distal end opposite to said hinge end and disposed proximate to said second end wall of said casing, said distal end of each of said support plates being pivotable toward and away from said main portion of said surrounding wall to help support said casing on the ground surface when said casing is disposed uprightly on the ground surface. 5. The barbecue grill assembly as claimed in claim 4, wherein said distal end of said rear support plate is provided with a wheel unit adapted to be in rolling contact with the ground surface when said distal end of said rear support plate is pivoted relative to said main portion of said surrounding wall. 6. The barbecue grill assembly as claimed in claim 4, wherein said front and rear support plates are provided respectively on said front and rear casing parts of said casing. 7. The barbecue grill assembly as claimed in claim 2, wherein said casing further includes a wheel unit mounted on said surrounding wall proximate to said second end wall and a pull member mounted on said surrounding wall proximate to said first end wall and disposed above said wheel unit, said wheel unit being adapted to contact rotatably the ground surface when said casing is in the upright position, said pull member being adapted to be gripped for pulling said casing and enabling said casing to move horizontally along the ground surface when said casing is disposed in the upright position. 8. The barbecue grill assembly as claimed in claim 7, wherein said surrounding wall of said casing includes a main portion and front and rear support plates, each of which has a hinge end hinged to said main portion of said surrounding wall and a distal end opposite to said hinge end and disposed proximate to said second end wall of said casing, said distal end of each of said front and rear support plates being pivotable toward and away from said main portion of said surrounding wall and being adapted to abut against the ground surface to help support said casing on the ground surface when said casing is disposed uprightly on the ground surface, said wheel unit being provided at said distal end of said rear support plate, said distal end of said rear support plate being pivotable relative to said main portion of said surrounding wall to enable said wheel unit to contact rotatably the ground surface. 9. The barbecue grill assembly as claimed in claim 8, wherein said pull member includes a ring portion and a mounting end portion which is connected to said ring portion and which is mounted pivotally on said surrounding wall so as to be pivotable between an unfolded position in which said pull member is unfolded from said surrounding wall, and a folded position in which said pull member is folded toward said surrounding wall, said surrounding wall being provided with means for locking said pull member in said unfolded position, said barbecue grill assembly further including a container which is retained removably on said ring portion of said pull member and which has a top opening, said cooking base of said cook unit being formed with a draining notch that is disposed above and that is registered with said top opening of said container when said pull member is locked in said unfolded position such that liquid which is drained via said draining notch can be collected in said container, said container being removable from said pull member to permit gripping of said ring portion of said pull member. 10. The barbecue grill assembly as claimed in claim 9, wherein said surrounding wall has a mounting recess for mounting said pull member, said mounting recess being defined by a pair of confronting side walls and a connecting wall interconnecting said side walls, each of said side walls bein
