Abstract
Smoking articles, such as filter cigarettes, are packaged in a metal box which is curved to a shape that conforms to the curvature of the human body so that the box can be comfortably carried in a shirt or pant pocket. The metal box comprises a lid and a five-sided tray each of which has rolled lips which interengage to mechanically and slidably retain the lid to the tray. The lid covers the open front of the tray and is slidable along an arcuate path corresponding to the radius of curvature of the lid to selectively open or close the front of the tray. The metal box is sealed with a shrinkable band, further packaged in a paperboard box and overwrapped with a polymeric film having a tear tape. The package is unique and attractive and provides several product differentiation features.
