Claims: We claim:

1. An integral packaging device for fragile articles comprising a base, a top, a base insert, and a top insert each of which is individually defined by its own sidewalls, each of said sidewalls having top and bottom edges,

said base being further defined by a bottom wall connected to the bottom edges of the sidewalls of the base, and having partitioning means therein,

said top being further defined by a top wall connected to the top edges of the sidewalls of the top, the bottom edge of one of the sidewalls of the top being connected by a hinge to the top edge of one of the sidewalls of the base,

said base insert including a lower wall connected to the sidewalls of the base insert, said lower wall being provided with a plurality of downwardly extending depressions each having an interior which is approximately the size of a lower portion of a fragile article for containing said lower portion, said base insert being hinged at the top edge of one of its sidewalls to the top edge of a sidewall of the base other than the top edge of the sidewall of the base hinged to the top, said base insert being sized to sit tightly into the base with said depressions being separated by said partitioning means of the base,

said top insert including an upper wall connected to the sidewalls of the top insert, said upper wall being provided with a plurality of upwardly extending depressions to match the depressions in the base insert, each depression having the approximately the size of an upper portion of a fragile article for containing said upper portion, said top insert being hinged at the bottom edge of one of its sidewalls to the bottom edge of its sidewall of the top other than the bottom edge of the sidewall of the top hinged to the base, said top insert being sized to fit tightly into the top,

said packaging device being nestable into a similar packaging device when the upper edges of the sidewalls of the base and base insert, and the bottom edges of the top and top insert of the packaging device are in approximately parallel plains, the base insert is not fitted into the base and the top insert is not fitted into the top.

2. The packaging device of claim 1 wherein the top is provided with a partitioning means for separating the depressions in the top insert when the top insert is fitted into the top.

3. The packaging device of claim 2 wherein the depressions in the top insert are spaced from the sidewalls, the top wall and the partitioning means of the top when the top insert is fitted into the top.

4. The packaging device of claim 1 wherein the depressions in the base insert are spaced from the sidewalls, the bottom wall and the partitioning means of the base when the base insert is fitted into the base.

5. The packaging device of claim 1 wherein the base has a volumn greater than the fragile articles and the downwardly expanding depressions are provided with a hole connecting the interior of the downwardly extending depressions with the base.
