The invention is directed to lightweight hydrostatic containers. The containers have thin walls and other surfaces that are maintained in tension by the liquid contained in the containers. The body portion is substantially circular and has a plurality of recesses. The recesses strengthen the container and provide points where the container can axially collapse. On the lower end the container has a base with an upwardly extending inner portion. This inner portion extends upwardly at least the vertical dimension of a spout of the container. A shoulder is on an upper end of the body portion, the shoulder supporting an axial spout. The hydrostatic containers preferably are packed in cartons in double squares. The cartons have sidewalls that do not extend above the body portion of the containers. The carton bottom wall has openings in alignment with the upwardly extending inner portion of each hydrostatic container. In this way the spouts of containers in a lower carton fit into the upwardly extending inner portions of the hydrostatic containers of an upper carton.
