The can (1) comprises a circumferentially continuous, unfolded foldable cylinder (2) having a longitudinal axis, and at least one closure member hermetically sealed to the foldable cylinder along an annular contact surface. The foldable cylinder has at least two longitudinally extending folding edges (3) formed and circumferentially located such that the foldable cylinder can be flattened, then unfolded for hermetic sealing of the closure member to the foldable cylinder. The closure member comprises a bottom of the can and is formed from a material selected from the group consisting of plastic, cardboard, and metal. The closure member comprises a bottom of the can and the bottom is in the form resulting from having been attached to the cylinder by at least one of the methods in the group consisting of rolling, adhesive bonding, and heat-sealing. |
