A protective packaging device for a shock sensitive product being shipped or stored in a rectilinear outer packaging container comprises a product receiving cavity having product contacting walls and a product supporting platform. A base portion located below the product receiving cavity has two pairs of deflection elements extending diagonally away from the corners of the cavity towards external outer packaging container contacting corners, and bottom outer packaging container contacting lips at the bottom of the base portion. The distances between adjacent pairs of outer packaging container contacting corners are substantially equal to the internal distances between adjacent pairs of corners of the outer packaging container. The deflection elements are adapted to flex away one from another, and the bottom outer packaging container contacting lips are adapted to spread away from one another, under shock loading conditions. Thus, shock protection is provided in three mutually perpendicular directions.

1. A unitary protective packaging device for a shock sensitive product being shipped in an outer packaging container, wherein a pair of said unitary protective packaging devices are employed, one at each end of a shock sensitive product, and an outer packaging container is rectilinear in configuration, said unitary packaging device comprising:a product receiving cavity surrounded by product contacting walls, and having a product supporting platform in the lower region thereof; anda base portion below said product receiving cavity, having two pairs of deflection elements extending diagonally away from the corners of said product receiving cavity towards external outer packaging container contacting corners, and having bottom outer packaging container contacting lips at the bottom of said base portion;wherein the distances between adjacent pairs of outer packaging container contacting corners are substantially equal to but not greater than the internal distances between adjacent pairs of corners of the outer packaging container with which said unitary protective packaging device is to be employed; andwherein said pairs of deflection elements are adapted to flex away one from another under shock loading conditions, and said bottom outer packaging container contacting lips are adapted to spread away from one another under shock loading conditions;whereby shock protection for a shock sensitive product in an outer packaging container and having a unitary protective packaging device at each end thereof, is provided in three mutually perpendicular directions. 2. The unitary protective packaging device of claim 1, wherein said product receiving cavity has a rectilinear configuration. 3. The unitary protective packaging device of claim 2, wherein a U-shaped channel is formed around the periphery of said product supporting platform. 4. The unitary protective packaging device of claim 2, wherein said product supporting platform is formed with an upwardly curved configuration. 5. The unitary protective packaging device of claim 2, wherein said product receiving cavity has a rectangular configuration, with one pair of opposed product contacting walls being longer than the other pair of product contacting walls. 6. The unitary protective packaging device of claim 5, wherein a downwardly directed notch is formed in each of said longer product contacting walls. 7. The unitary protective packaging device of claim 5, wherein a downwardly directed notch is formed in at least one pair of opposed product conducting walls. 8. The unitary protective packaging device of claim 1, wherein each of said deflection elements is formed at least at said external outer packaging container contacting corners so as to slope downwardly and outwardly. 9. The unitary protective packaging device of claim 1, wherein said bottom outer packaging container contacting lips extend outwardly from said base portion. 10. The unitary protective packaging device of claim 5, wherein an outwardly directed stiffening rib is formed in said base portion between said external outer packaging container contacting corners on the sides of said base portion beneath said longer product contacting walls. 11. The unitary protective packaging device of claim 4, wherein an outwardly directed stiffening rib is formed in said base portion between said external outer packaging container contacting corners in each of at least one pair of opposed sides of said base portion.
