A can structure for detachable coupling of at least two cans. The detachable coupling structure includes a plurality of grooves recessed on an outside surface of a bottom peripheral ring of each can such that each of them has a receiving portion and a locking portion. A plurality of projections extend inwardly from an inside surface of a top peripheral flange of each can at positions corresponding to the grooves. In accordance with the above structure, the two cans are detachably coupled to each other by inserting the projections of one can in the receiving portion of the corresponding grooves of the other can and turning the two cans in opposed directions. In a second embodiment of this invention, the projections are formed by partial inward bending of an edge of the top peripheral flange of each can at positions corresponding to the grooves. The detachable coupling of the cans can be repeated several times so as to form a line of cans without causing any problem. Neither a removable tap nor a tap handle of the lid of the can causes a hinderance when coupling the cans to each other. Accordingly, the cans, irrespective of presence of their taps and tap handles, cause no problem in their coupling.
