Abstract
A smooth operating cargo box which is simply and easily assembled by first erecting the side panels on the box base by engaging outwardly opening end hooks extending along the bottom edges of the sides with inwardly opening side hooks extending along the side edges of the base, then erecting the back panel by sliding it in a direction perpendicular to the plane of the panel toward the rear of the container to engage outwardly open end hooks along the side and bottom edges of the back panel with inwardly directed side hooks extending along the rear edges of the base and side panels, then erecting the front panel by engaging an outwardly opening end hook extending along the bottom edge of the panel with an inwardly opening side hook extending along the front edge of the base and rotating the panel around its bottom edge from inside toward the outside of the container to engage inwardly opening end hooks along the side edges of the front with outwardly opening side hooks extending along the front edges of the sides, and finally sliding the top panel in the direction of its plane from the rear toward the front of the box to engage inwardly opening end hooks along the sides of the top with outwardly opening side hooks on the top edges of the sides and to engage an inwardly opening side hook along the back edge of the top with an outwardly opening end hook extending along the top edge of the back panel. Latches are provided for clamping the front edge of the top to the top edge of the front. An alarm system gives a signal in the event that an unauthorized person attempts either to open the container or to break through a panel thereof in an effort to gain access to the contents.
