IMPROVEMENTS IN AND RELATING TO CONTAINERS ABSTRACT OF THE DISCLOSURE A method of, and apparatus for, making a frusto-conical container from a blank having a base panel and side panels which are folded relative to the base, the blank being clamped between tools of an inject- ion moulding machine and seamed by injected material fed along one face of the side panels, the other face of the side panels spanning a circumferential channel into which they are forced by injected material to form a circumfer- ential bead, at the axial seams the channel being reduced in depth to support the side panels against displacement of the edges by injected material, thereby to inhibit injected material from reaching that face of the blank nearest the channel.
