The invention relates primarily to the field of packaging goods etc. It also relates to compressive strength provision for boxes, columns and other load bearing situations. The technical problem is that packages, columns etc., crush or buckle under compressive loads. This problem is solved by the use of certain principles of physics in this invention which consists of using a circular, cylindrical or similar shaped device placed inside a square or similar shaped box or device with the object of increasing the compressive strength of the whole. The principal uses of the invention are in packaging tea, powders, liquids etc., in cartons or similar receptacles and also in building and civil construction works etc. |
