  • Patent number: 4036254
    Abstract: The present invention relates to a new container that can be displaced by rotary force, consisting of a continuous sheet that assumes a form similar to a cylindrical surface, generated by a rectangle whose shorter sides have been substituted by convex semicircumferences, when it rotates around an axis that is very close and parallel to one of the long sides. An element is then placed in the direction of the axis and forms the axis of rotation. This element is held fast by the container when the latter is filled with fluid or other matter that induces multidirectional pressures of sufficient magnitude to cause the element installed, when impelled by a force, preferably along the axis but from either direction, to pull with it the enclosed sheet, thus displacing the container by rotary force over the supporting surface.
