Abstract: A package for storing and shipping a heavy object, such as a compressor for an air-conditioning system, includes a base formed from a rigid material and having recesses which receive feet at the bottom of the object and flaps which fold over the recesses and capture the feet in them, thus securing the object to the base. The package also includes a box having side walls and top and bottom walls. The base, with the object secured to it, fits into the box with the base against the bottom wall of the box and the object surrounded by the side walls of the box. A sleeve fits into the box between the base and the top wall and holds the base against the bottom wall. A tray fits within the sleeve above the object where it rigidifies the sleeve, enabling the sleeve to maintain its cross-sectional configuration, and further serves as a receptacle for accessory items.
