Abstract: An end-loading reinforced mailing or shipping box is formed from a single blank of sheet material and includes integral extensions which are wrapped about the box to define a surrounding protective shipping wrapper. The box may be of the top-opening variety. The protective wrapper includes end flaps which provide additional reinforcement at the ends of the package. Assembly of the integral box and wrapper requires only one straight line gluing operation by the box manufacturer and only one folding and gluing operation by the packager who receives the box and wrapper in a partly folded and glued condition. The packager end loads the products or articles into the open ended package and then needs only to fold and glue the end flaps. No right angle or timed folding or gluing operations are required. The package includes tear strips which facilitate opening a wall of the wrapper and permit the inner box to be removed. Thereafter, the box-like wrapper may be used as a protective storage box for the inner box.
