Disclosed is an inflatable container suitable for use as a portable aquarium. The inflatable container has an upper open end and side walls which are easily and economically constructed from a single sheet of flexible film material. The sheet is folded upon itself into substantially two overlapping half sections with portions of each half section being sealed together to form four side panels. The remaining portions of the overlapping half sections form an inflatable tubular, flexible framework including an upper and a lower tubular rim and at least four upstanding tubular columns which surround the side panels. The tubular framework and side panels are formed with only two sealed seams joining the longitudinal and lateral edges of the film sheet, one of which extends longitudinally along the surface of the lower tubular rim and the other of which extends laterally along the surface of one of the upstanding tubular columns. The upper tubular rim of the framework surrounds the upper open end of the container and is essentially seamless except for a portion of the lateral seam extending along the surface of the upstanding tubular column. A bottom panel is joined to the lower tubular rim and valve means are mounted in the framework for inflating the container.

An inflatable container having an upper open end, said container comprising: at least four flexible side panels; an inflatable, tubular, flexible framework surrounding said panels, said framework including an upper and a lower tubular rim and at least four upstanding tubular columns; said inflatable, tubular framework and said side panels being formed from a single sheet of flexible film material folded upon itself along a longitudinal fold line into two overlapping, substantially rectangular sections each of which has its opposite lateral edges aligned with the opposite lateral edges of the other section, said overlapping rectangular sections being sealed together by a longitudinal seam extending between the opposite lateral edges of each section at a point spaced from said longitudinal fold line and by at least four continuous seams enclosing at least four separate areas within the space between said longitudinal fold line and said longitudinal seam, each of said overlapping rectangular sections having one of its opposite lateral edges sealed to the other of its opposite lateral edges by a lateral seam extending between said longitudinal fold line and said longitudinal seam, the arrangement being such that each one of said continuous seams defines one of said side panels while the remaining portions of said overlapping rectangular sections form said tubular framework with said longitudinal seam extending along the surface of said lower tubular rim and with said lateral seam extending along the surface of one of said upstanding tubular columns; said upper tubular rim surrounding said upper open end of said container and being seamless except for a portion of said lateral seam extending along the surface of said one upstanding tubular column; said upper and lower tubular rims communicating with each other through at least one of said upstanding tubular columns; a flexible bottom panel joined to said lower tubular rim and covering the bottom end of said container; and a valve mounted in one portion of said framework for inflating the entire framework through said communicating upstanding tubular column.
