Abstract
Abstract A package and a process for making the same is disclosed. The package is especially useful for cigarettes and is of the hard cup type being made with a packing body of cardboard, pasteboard or similar material. The body of the package is provided on the outside with a moisture and odor (aroma) tight coating and, at least at the upper edge, a strip of inside tin foil wrapping is attached for the formation of a front fold. The arrangement simplifies the package blank and results in a finished package having an overall metal coating.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
202 words
A method for the production of cigarette pack blanks from a web of relatively thick, stiff cardboard, paste board or the like, said blanks being subsequently folded in a U-shape around the front, bottom and rear surfaces of a rectangular block of cigarettes, and wherein the lateral edges of said web coincide with the upper edges of the blanks laid out thereon, after folding, characterized by the steps of: (a) coating one entire surface of said web (34) with a moisture and aroma-proof metal coating (17), said one surface being the outer surface of the folded cigarette pack, (b) applying by gluing or the like a pair of relatively thin and pliable, continuous strips of metal foil (11a, 11b) to the respective lateral edges of said web on the other side thereof opposite said metal coating such that the outer edges of said metal foil strips extend outwardly beyond the lateral edges of said web, (c) applying a relatively thin and pliable sealing layer (30, 33) of metal foil to said other side of said web at least in the areas which form the four bottom corners of the folded pack, and (d) separating said blanks from said web by cross stamping.
