ABSTRACT:
The present invention provides a low cost paperboard sleeve package for holding tubs in a stacked manner. The sleeve has an octagonal configuration to provide stacking strength and space efficiency. The top of the sleeve is provided with an openable retainer to allow removal of the tubs. The bottom of the sleeve has retaining flaps which extend upward and inward to engage the lid and upper portion of the lowermost tub and which permit the stack of tubs to be loaded into the sleeve from the bottom. This supporting engagement enables the lowermost tub to support the weight of the tubs stacked above.
