Abstract
Abstract A pair of rigid frames having central openings are each covered with a pliable material which is forced in intimate contact with a fragile article to be packaged. Central openings allow passage of the fragile article which is suspended between the two pliable materials. Pliable material and friction limits the handling shock-type loads which may be transmitted to the fragile article in one direction, and cushions loads in other directions. Frames can be positioned within an enclosure package so that motion of the fragile article during handling can be tolerated. A single pair of pliable covered frames can serve as packing for a wide variety of solid materials, including multiple items or irregular shapes and heavy articles, with no further protection required.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
209 words
In combination with a rigid shipping container or the like, a packing device for resiliently suspending an object inside said container which comprises: a first planar sheet of cardboard having a first opening; a first film of pliable material covering said first opening and being attached on all sides to said first sheet; a second planar sheet of cardboard having a second opening; a second film of pliable material covering said second opening and being attached on all sides to said second sheet; means for releasably securing said first and second sheets within said container in a generally parallel, spaced-apart and face-to-face alignment wherein each of said films is in pressing contact with opposite sides of said object sandwiched therebetween wherein the pliable films apply tension and friction to said object, and wherein said means for securing are shaped and positioned to apply equal forces to said sheets to immobilize said object between said films in the absence of any load being applied to said object other than gravity and in whatever position said container may rest and to limit, by tension and friction of the films applied to said object, the movement of said object within said container when said container is subject to impacts from various directions.

In combination with a rigid shipping container or the like, a packing device for resiliently suspending an object inside said container which comprises: a first planar sheet of cardboard having a first opening; a first film of pliable material covering said first opening and being attached on all sides to said first sheet; a second planar sheet of cardboard having a second opening; a second film of pliable material covering said second opening and being attached on all sides to said second sheet; means for releasably securing said first and second sheets within said container in a generally parallel, spaced-apart and face-to-face alignment wherein each of said films is in pressing contact with opposite sides of said object sandwiched therebetween wherein the pliable films apply tension and friction to said object, and wherein said means for securing are shaped and positioned to apply equal forces to said sheets to immobilize said object between said films in the absence of any load being applied to said object other than gravity and in whatever position said container may rest and to limit, by tension and friction of the films applied to said object, the movement of said object within said container when said container is subject to impacts from various directions.
Claim 3
Dependent Claim
44 words
The combination of claim 1 which also comprises friction-increasing means interposed between each of said films and of said opposite sides of said object wherein said friction-increasing means comprise a surface in contact with said film made from the same material as said film.
Claim 4
Dependent Claim
16 words
The combination of claim 2, wherein said friction-increasing means also comprise a surface made of cardboard.
Claim 5
Dependent Claim
25 words
The combination of claim 1, also comprise an object separator made of cardboard, and shaped and dimensioned to separate multiple objects held between said films.
Claim 6
Dependent Claim
20 words
The combination of claim 4, wherein said object separator is a planar section of cardboard having a plurality of apertures.
Claim 7
Dependent Claim
34 words
The combination of claim 5 wherein said planar separator in placed parallel to said frame elements, said separator having openings, each opening large enough to pass a portion of one of said multiple objects.
