Abstract:
A unitary product cushioning structure for supporting a shock sensitive product in an outer packaging container, and for permitting co-packaged accessories to be placed also in the same outer packaging container together with a shock sensitive product, said unitary product cushioning structure being formed of a moldable resilient plastics material;wherein said unitary product cushioning structure is adapted to provide shock absorption protection for a shock sensitive product during shock loading conditions in three mutually perpendicular directions; and wherein said unitary product cushioning structure is further adapted to provide impact protection for a shock sensitive product from co-packaged accessories for said shock sensitive product, during shock loading conditions; said unitary product cushioning structure comprising: at least two pairs of outer container contacting walls being arranged in mutually perpendicular orientations for providing contact with an outer packaging container in the same two mutually perpendicular directions as said mutually perpendicular orientations; at least one flexible shock absorbing spring transition section formed inwardly of each of said outer container contacting walls, each flexible shock absorbing spring transition section having an outer surface; and a product supporting region having at least a pair of product contacting wall corner structures; wherein said product supporting region further comprises a product supporting platform to provide product support in a mutually perpendicular orientation to the orientation of each of said outer container contacting walls; wherein each of said wall corner structures has a pair of inner product contacting walls in mutually perpendicular orientation to said product supporting platform, a pair of outer product supporting region defining walls, and an upper ridge therebetween; wherein each of said flexible shock absorbing spring transition section is formed inwardly of the respective outer container contacting wall with which it is associated, and outwardly of said outer product supporting region defining walls; wherein each respective inner product contacting wall is adapted to provide shock absorption support for a product during shock loading conditions in a respective first or second one of said three mutually perpendicular directions; wherein said product supporting platform is adapted to provide shock absorption support for a product during shock loading conditions in a direction perpendicular thereto, and perpendicular to said first or second one of said three mutually perpendicular directions, whereby shock absorption protection is provided for a shock sensitive product during shock loading conditions, in three mutually perpendicular directions; wherein said product supporting platform has a plurality of ribs formed therein, each extending perpendicularly in a direction away from said product supporting platform to a lower extent limit; and wherein each of said outer container contacting walls has a bottom edge which provides an outer packaging container contacting surface to contact a surface of an outer packaging container which is in a plane that is mutually perpendicular to the planes of said pairs of inner product contacting walls; wherein the vertical distance between the plane of said bottom edges and the plane of said lower extent limit is at least as great as the thickness of any accessory for a shock sensitive product to be supported by said product supporting platform; whereby a void is defined between said lower extent of each of said plurality of ribs and the plane of said bottom edges, and between said flexible shock absorber spring transition sections associated with said outer container contacting walls; and whereby an accessory may be co-packaged with a related shock sensitive product by being placed within said void.
