Abstract: 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.

Abstract: This invention is concerned with inflatable plastic baby baths similar in shape to a rubber tire inner tube having an impervious web across the ring. The web is preferably midway between the top and the bottom of the inflatable tube or annulus, and by inflating the article while hot during manufacture a smooth and wrinkle-free appearance can be produced. Such a plastic bath can be made virtually immovable on a smooth surface by expelling air from under the web and causing a partial vacuum. The diameter of the inflated tube is sufficiently great relative to the width of the web to prevent the web touching the supporting surface in normal use.
