ABSTRACT:
A dough container is described which consists of a spiral body stock winding of paperbased material, a liner bonded to the interior of the body and label bonded to the exterior surface of the body material. Each of these layers consists of a helically wound strip. The side edges of the body stock strip lie adjacent one another to form a butt joint and the liner is provided with a zigzag fold or pleat substantially in alignment i.e. beneath the butt joint in the body stock. Metal ends are crimped to each end of the can to form the top and the bottom. During opening, the pleat allows the dough which is usually under pressure to expand, separate the butt joint and then rupture the liner.
