Abstract:
A unitary product cushioning device for supporting a shock sensitive product in an outer packaging container, said unitary product cushioning device being formed of a moldable resilient plastics material, and comprising:a post structure having a first closed end and a second open end; anda first curved ridge formed at at least a first side of said post structure, said first curved ridge terminating at a first container contacting flange at the end thereof remote from said open end of said post structure;wherein a portion of at least said first curved ridge at said first side of said post structure presents a product supporting surface;wherein a further portion of at least said first curved ridge at said first side of said post structure is curved in a direction outwardly and away from said post structure;wherein, when said unitary product cushioning device is placed in an outer packaging container having parallel and planar top and bottom surfaces and at least three planar side surfaces, each of which is perpendicular to said planar top and bottom surfaces, so that said post structure extends towards a corner defined by at least two of said planar surfaces, said first container contacting flange will contact one of said planar surfaces, and said first product supporting surface will be parallel to said one of said planar surfaces; andwherein, when a shock load is applied to said unitary product cushioning device in a direction towards said one of said planar surfaces, said further portion of said first curved ridge at said first side of said post structure will at least temporarily be further curved in a direction outwardly and away from said post structure, and said product supporting surface will at least temporarily move closer to said one of said planar surfaces.
