A method of forming a solderless bell, having a single sound opening, out of a blank within a strip, is disclosed, which comprises the steps of: forming a crown within the blank; separating the blank from the strip, said blank comprising a central portion and peripheral flap portions; inserting a clapper within the central portion; and closing the peripheral flap portions around the central portion, to form said sound opening, thereby encasing the clapper within the central portion and the peripheral flap portions to form the bell. A solderless bell is disclosed which comprises: a container, a clapper located within said container; a single sound opening consisting of a single longitudinal slit located at the bottom of the container; and a crown arranged on the top of said container, said crown being integral with the container and protruding therefrom.
