ABSTRACT:
A plurality of stacked cups are nested and axially constrained against separation to assure cup-to-cup sealed engagement with portions of adjacent cups to prevent sifting of product from sealed enclosures between adjacent cups. The cups are thick walled, one piece molded plastic cups formed with integral radially inwardly projecting shoulder means spaced upwardly of the bottom wall of the cup. A marginal portion of an adjacent telescoped cup abuts and rests on the shoulder means to form the sealed enclosure for the deliquescent or hygroscopic material which can be reconstituted with the addition of water.
