Abstract:
1. A fluid container apparatus with controlled floatation means comprises: A. a helical spring member means made of continuous wire formed into multi uniform pitch turns whereby said helical spring wire turns provide constructional support of the container apparatus helical wall strip and constructional support to its end covers that are mechanically secured to said helical spring by being threaded into said spring wire turns and B. helical strip wall with flexible cross section that is wrapped between each helical spring wire turn and the adjacent wire turn of said helical spring with its right strip lateral side attached to the left strip lateral side along each said helical wire turn whereby said wire turn is encapsulate between lateral right and left side of said helical strip wall and said helical strip wall creates continuous sealed wall and C. helical clamping means with lateral elongated cavity structurally attach together said right and left side cross sectional lateral protrusion of said helical strip wall around each helical spring turn whereby said helical clamping means fix together external right and left sides of said helical strip wall to form sealed structural wall of said container apparatus and D. multiple cross bar connecting members mechanically connect between said helical clamping means across said wire turn whereby said connecting cross bar members provide structural longitudinal and lateral stiffness and attachment means between multiple container apparatuses and E. end cover members located at each end of said helical spring comprising
