Abstract
Abstract A packing device for protecting an item housed in a container essentially consisting of a plurality of shock absorbing elements, each having an integral recess along one of its sides, and a loop of stretchable elastomeric cord which frictionally interfits within the recess. Preferably, the cushioning elements are of a resilient and non-abrasive foam material adapted and configured to be removably snap-fitted onto the cord at desired positions. In use, and depending on the desired packaging configuration, the cord with the cushioning elements attached is stretched either about an item to be shipped within a single container, or about an inner container which is then snugly fitted (i.e., with a tight fit) within an outer container. The invention can also be practiced by placing the device about an item or container to be shipped, and not employing additional outside packaging about the mounted packing device.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
135 words
A shipping pack for cushionably protecting an object, said pack comprising: a plurality of shock-absorbing cushioning elements of resilient material defining an integral recess along the length of at least one side thereof, said recess having a restriction of a first dimension and a central portion of a second greater dimension for receiving a cord; and a stretchable continuous elastomeric cord when exhibits resilient elongation during stretching of at least twenty percent and is interfitted within the central portion of said recess and held therein by said restriction; said plurality of cushioning elements being removably and adjustably positionable in spaced-apart relation along said elastomeric cord, whereby said cord may be stretched manually to surround an object to be protected and said cushioning elements may be adjusted to provide spaced-apart cushioned regions on a said object.
Claim 2
Dependent Claim
135 words
A shipping pack for cushionably protecting an object, said pack comprising: a plurality of shock-absorbing cushioning elements of resilient material defining an integral recess along the length of at least one side thereof, said recess having a restriction of a first dimension and a central portion of a second greater dimension for receiving a cord; and a stretchable continuous elastomeric cord when exhibits resilient elongation during stretching of at least twenty percent and is interfitted within the central portion of said recess and held therein by said restriction; said plurality of cushioning elements being removably and adjustably positionable in spaced-apart relation along said elastomeric cord, whereby said cord may be stretched manually to surround an object to be protected and said cushioning elements may be adjusted to provide spaced-apart cushioned regions on a said object.
Claim 3
Dependent Claim
55 words
The shipping pack of claim 1 in combination with a container housing said object, and, wherein said elastomeric cord is in the form of a loop stretchable around said container, and said cushioning elements comprise a block for placement on a side surface of said container with said internal recess facing away from said container.
Claim 4
Dependent Claim
49 words
The shipping pack of claim 1, wherein said cushioning elements comprise of plurality of corner receiving units each including an orthogonal top panel, and two orthogonal blocks forming side panels extending perpendicularly in the same direction from adjacent side edges of said top panel to form an interior cavity.
Claim 5
Dependent Claim
38 words
The shipping pack of claim 1, wherein said cushioning elements comprise a plurality of side edge straddling units including a pair of orthogonal blocks joined along the height dimension thereof in perpendicular arrangement to form an interior cavity.
Claim 6
Dependent Claim
73 words
The shipping pack of claim 1, wherein said resilient material comprises: a laminate comprising a first polymeric foam material having a first density adhered to a second polymeric foam material having a different, second density, said laminate being further characterized by the property of reducing the force applied to an object on impact relative to an other-wise identical cushioning element comprising a single foam polymeric material of either said first or second density.
Claim 7
Dependent Claim
38 words
The shipping device of claim 5 in combination with a container housing said object, and, wherein said first and second polymeric foam materials are adhered together in a plane substantially parallel to an adjacent surface of said container.
Claim 8
Dependent Claim
17 words
The shipping device of claim 5, wherein said first and second polymeric foam materials comprise different polymers.
Claim 9
Dependent Claim
24 words
The shipping device in claim 5, wherein the ration of the densities of said first and second polymeric foam materials is at least 0.66.
Claim 10
Dependent Claim
18 words
The shipping device of claim 5, wherein at least one of said foamed polymeric materials comprises a polyolefin.
Claim 11
Dependent Claim
26 words
The shipping pack of claim 1 wherein said restriction is characterized by an opening having a height less than the cross-sectional diameter of said central portion.
Claim 12
Dependent Claim
26 words
The shipping pack of claim 1 wherein said restriction is characterized by an opening having a height less than the cross-sectional diameter of said elastomeric cord.
Claim 13
Dependent Claim
15 words
The shipping pack of claim 1 wherein the said elastomeric cord forms a continuous loop.
Claim 14
Dependent Claim
19 words
The shipping pack of claim 12 further including means for adjustably fastening the ends of the elastomeric cord together.
