ABSTRACT:
A method for forming an aluminum cigarette package includes the step of cutting elliptical blanks from an aluminum sheet and shaping the blanks by progressive drawing operations into a lid and a body. The lid and body are joined by a flexible label that serves as a hinge that allows the lid to be pivoted relative to the body to open and close the pack. In an alternative embodiment of the invention, a drawn aluminum body is provided with a flat cap member having an aperture and a resealable closure. The invention includes a metal package made by the method of the invention.
