A materials container (10) having an annular rim (21) formed about an open end (17) thereof wherein the annular rim (21) is formed as an elongated, outwardly rolled curl. A lid (27) is applied to the pail body (11) of the materials container (10) and is secured hereto by the crimping of a series of lugs (41) formed about the circumference of the lid (27) into tight metal-to-metal engagement about the annular rim (21). As the lugs (41) are crimped onto the annular rim (21), the annular rim (21) is further rolled and reformed into a tight, completed compound curl about which the lugs (41 ) of the lid are tightly wrapped so as to form a tight metal-to-metal seal between the pail lid (27) and the pail body (11) of the materials container (10).
