Abstract
A low cost paperboard package includes a tray with bendable flanges protected by an outer cover member. In one embodiment, a wrap-around blank comprising a generally rectangular paperboard tube protects the tray prior to use. In another embodiment, a folded carton with end wall panels protects the tray prior to use. In both embodiments, the movement of the tray within the outer cover member is restrained by the coaction of the outer cover member and the spring action of the bendable tray flanges. The distance between the side walls of the outer cover member is less than the distance between the outer edges of the tray flanges when they are fully extended. By bending the flanges downwardly, the tray can be slipped into a blank of minimal size. The friction between the tray flanges and the blank's side walls resists movement of the tray.
