<p>The invention provides a tubular container whose wall at at least one end is curled over to form a bead for engagement with a closure, the said curled over end portion of the container wall being of thinner gauge than the adjacent wall portion. The container can have a foil diaphragm secured across the beaded end, and may have a reusable overcap or lid engaging around the bead and closing the beaded end of the container. The beaded end of containers according to the invention is more durable than that of prior constructions, and can provide a better seat for a sealing diaphragm.</p> |
