Abstract: A stacking system for containers placed in a shipping carton. The system includes at least one layer of containers and preferably multiple layers of containers with each container of each layer held in nonmoveable relationship between upper and lower trays of identical configuration. Each tray includes a plurality of compartments spaced from one another at equal intervals adapted to receive the bottom portions of the containers and a plurality of conical recesses adapted to receive the conical tops of the containers. The compartments are formed on the top sides of the trays and the conical recesses are formed on the bottom sides of the trays. Thus each tray can be used to lock either the conical tops of each layer of containers of the bottom portions of a layer of containers. The containers are spaced apart and kept from lateral movement at both their tops and their bottoms. The edges of the trays have locking flanges to hold the trays in the cartons.

Abstract: A system for hanging a packaged product such as a container having a flat-topped plastic cap from a rod at a display rack. A plastic tab is integrally mounted to the flat top of the cap. The tab is movable between nonoperative and operative positions, wherein in the nonoperative position the tab lies flat against the top of the cap, and in the operative position the cap is rotated to a position perpendicular to the top of the cap. The tab includes a loop portion forming a hole and a hinge portion that is integrally and flexibly connected to the loop portion and to the cap. The top of the cap forms a recess that is adapted to snugly receive the tab. The hole is adapted to receive the rod of the display rack so as to support the container. The tab and the hole can have various configurations. Two tabs are provided for large caps.
