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.

A package comprising: a tray having a bottom wall panel, plurality of side wall panels and a first pair of flanges respectively extending outwardly from opposite ones of said side wall panels, said flanges being bendable about fold lines at the upper edges of said side wall panels from an extended position to a tucked position, the distance between respective outer edges of said first pair of flanges being reduced when the latter are bent from said extended positions thereof to said tucked positions thereof, each of said flanges being biased to return from said tucked position thereof to said extended position thereof; and a generally rectangular outer cover member including top and bottom wall panels connected by side wall panels, the distance between at least portions of said side wall panels of the outer cover member being less than the distance between the outer edges of said flanges when the latter are in said extended position thereof, said tray being insertable into the outer cover member when the flanges are bent to said tucked position thereof, said tray being retained in the outer cover member by frictional engagement produced by outward biasing of said flanges against said side wall panels of the outer cover member.
