Abstract
A carton-liner assembly comprises an outer carton and a liner disposed within and affixed to the carton. The carton includes opposing top and bottom carton walls, opposing front and back carton walls, and opposing first and second side carton walls. The front carton wall and the opposing side carton walls include a continuous tear strip for opening up the carton from a sealed form to form a lid hingedly connected to a base. The liner includes a front liner wall and opposing side liner walls adjacent to the respective front carton wall and opposing side carton walls of the carton. The liner optionally includes a back liner wall adjacent to the back carton wall of the carton. To reduce the weight of the carton-liner assembly, the walls of the liner include a series of stripped-out areas. Preferably, the stripped-out areas are elongated in a vertical direction and have respective arrow-shaped lower ends. Each liner wall includes a pair of stripped-out areas separated by a center strut. The liner walls intersect at vertical corner posts, and the pair of stripped-out areas on each liner wall are spaced away from these vertical corner posts.
