<p>REINFORCED PAPERBOARD CAN A reinforced paperboard can is constructed from a pair of rectangular, superposed paperboard blanks each of which is transversely scored to form side and end walls of the can. Those panels of each blank which are to constitute the side walls are uniform in size and those panels which are to constitute the end walls also are uniform in area. Each of the blanks is scored longitudinally whereby flaps are formed along one edge of the panels of one blank and which are separated by slits so as to enable the flaps to form a bottom closure for the can. The other blank has a smaller area than the first blank so that the other blank has tabs of less area than the flaps and which are separated from one another by slits so as to enable the tabs to overlie the flaps. The can thus produced has double thickness side and end walls, and the closure flaps adjacent the side and end walls also are double thickness. A top closure for the can may be provided by flaps similar to the first mentioned flaps or by a separate top member which may be crimped to the side and end walls.</p> |
