pack cigarette case was introduced in 1955 by Philip Morris. This successfully prevents the crumpling of cigarettes when kept in a pocket or handbag. The hard pack is designed to make the smoker look at the brand name and logo on the top of the pack every time on opening, keeping the brand fresh in the consumer's mind and potentially increasing brand loyalty.
