Abstract
Abstract A plastic packing device, die cut from a block of foam plastic, has legs pivotable out of a central cavity, forming a collar connected by a living hinge to the legs. The legs have widened bottom portions that snap over the surface of the collar to help maintain the legs in a perpendicular position. A support tab, connected to each leg by a second living hinge colinear with the first, is pivotable to a position between the leg and the collar, to maintain the leg in the perpendicular position.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
91 words
A foldable plastic packing device, comprising: a collar, having longitudinal elements and lateral elements, that frames a central cavity, at least one leg element hingedly connected to a lateral element and pivotable into said central cavity, said leg element having widened portions to project over said collar and maintain said leg element in a position perpendicular to said collar, a support tab, hingedly connected to said leg element, positionable between said leg element and said lateral element to assist in maintaining said leg element in a position perpendicular to said collar.
Claim 2
Dependent Claim
91 words
A foldable plastic packing device, comprising: a collar, having longitudinal elements and lateral elements, that frames a central cavity, at least one leg element hingedly connected to a lateral element and pivotable into said central cavity, said leg element having widened portions to project over said collar and maintain said leg element in a position perpendicular to said collar, a support tab, hingedly connected to said leg element, positionable between said leg element and said lateral element to assist in maintaining said leg element in a position perpendicular to said collar.
Claim 3
Dependent Claim
12 words
The device of claim 1 in which said longitudinal elements are expandable.
Claim 4
Dependent Claim
38 words
The device of claim 1 in which said leg element is hingedly connected to said lateral element by a first living hinge and said support tab is hingedly connected to said leg element by a second living hinge.
Claim 5
Dependent Claim
17 words
The device of claim 3 wherein said first living hinge and said second living hinge are colinear.
Claim 6
Dependent Claim
20 words
The device of claim 1 wherein said collar, said leg, and said support tab are pivotable into a co-planar relationship.
Claim 7
Dependent Claim
144 words
A plastic packing device comprising a block of plastic, die-cut to form: a collar having outer longitudinal elements and outer lateral elements that surround an interior portion, a leg element in said interior portion, hingedly connected by a first living hinge to one of said outer lateral elements, and pivotable out of said interior portion to a position perpendicular to said collar, said leg element having widened portions adjacent said living hinge to project over said collar and maintain said leg element in said position perpendicular to said collar, a support tab, hingedly connected to said leg element by a second living hinge colinear with said first living hinge, and pivotable oppositely from said leg element out of said interior portion, to a position between said leg element and said one lateral element to assist in maintaining said leg element in said perpendicular position.
Claim 8
Dependent Claim
144 words
A plastic packing device comprising a block of plastic, die-cut to form: a collar having outer longitudinal elements and outer lateral elements that surround an interior portion, a leg element in said interior portion, hingedly connected by a first living hinge to one of said outer lateral elements, and pivotable out of said interior portion to a position perpendicular to said collar, said leg element having widened portions adjacent said living hinge to project over said collar and maintain said leg element in said position perpendicular to said collar, a support tab, hingedly connected to said leg element by a second living hinge colinear with said first living hinge, and pivotable oppositely from said leg element out of said interior portion, to a position between said leg element and said one lateral element to assist in maintaining said leg element in said perpendicular position.
