There is described a carton which comprises first, second, third and fourth rectangular side walls hingedly connected in sequence along parallel edges, first and second pairs of opposed overlapping end walls connected to the edges of first and third walls whereby the side walls and the opposed end walls form an enclosure when the overlapping end walls are adhered together and the first and the fourth rectangular side walls are adherently connected by use of an extended end portion of either the first or fourth rectangular side walls, there being tear lines where each of the pair of end walls are connected to the edges of the first side wall, together with a tear line extending across the fourth side wall to both ends of the adjacent edge of the first side wall, whereby the first side wall can be disengaged from a portion of the fourth side wall and from the end walls so that the carton can be opened flat when all three tear lines are severed. |
