Abstract
Abstract Lightweight, non-nestable packing peanuts formed of recycled newspaper of molded hollow thin wall shell form preferably of cup shaped configuration have flanges, apertures, and double wall dividers integrally molded therein. A radial flute over the vertical height of the exterior wall of the shell provides shape stability to a portion of the shell to resist physical crushing of the shell and facilitates the structural cushioning of packed fragile objects in cartons or the like for shipping purposes. The shell is rendered resilient over other portions for absorbing the energy resulting from impact forces transmitted through the fold filled towards a packed fragile object. A divider having spaced parallel walls may extend from an end of the shell at the base and include an integral transverse wall to separate the shell into two halves which may be flexed towards and away from each other, at the gap between the divider walls.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
96 words
A lightweight non-nestable packing peanut for use as a loose fill material in packing objects within sealed cartons, with the fill material under compression said packing peanut comprising: a cellulose fiber, biodegradable molded hollow, thin walled shell of recycled newspaper, said shell including means within a portion of said shell for providing shape stability thereto for resisting physical crushing of said shell thereby structurally cushioning said packed objects, and means for rendering said shell resilient over a portion thereof for absorbing the energy resulting from impact forces transmitted through said fill material towards said packaged objects.
Claim 2
Dependent Claim
96 words
A lightweight non-nestable packing peanut for use as a loose fill material in packing objects within sealed cartons, with the fill material under compression said packing peanut comprising: a cellulose fiber, biodegradable molded hollow, thin walled shell of recycled newspaper, said shell including means within a portion of said shell for providing shape stability thereto for resisting physical crushing of said shell thereby structurally cushioning said packed objects, and means for rendering said shell resilient over a portion thereof for absorbing the energy resulting from impact forces transmitted through said fill material towards said packaged objects.
Claim 3
Dependent Claim
35 words
A packing peanut as claimed in claim 1, wherein said shell is of dome shape, having an open end and said flanged base extends radially from said open end of said hollow thin wall shell.
Claim 4
Dependent Claim
35 words
A packing peanut as claimed in claim 2, wherein said dome shaped shell comprises a cylindrical portion integral with said flanged base and said cylindrical portion terminates in a spherical portion remote from said base.
Claim 5
Dependent Claim
34 words
A packing peanut as claimed in claim 2, wherein said shell includes an integral divider extending longitudinally generally from said open end to the end of said dome shaped shell remote from said base.
Claim 6
Dependent Claim
34 words
A packing peanut as claimed in claim 3, wherein said shell includes an integral divider extending longitudinally generally from said open end to the end of said dome shaped shell remote from said base.
Claim 7
Dependent Claim
70 words
A packing peanut as claimed in claim 4, wherein said divider comprises spaced parallel walls extending from the end of said shell remote from said base towards said base integral with said shell and including an integral transverse wall joining the same and forming hinges therewith, whereby said shell is separated into two halves which may flex towards and away from each other at the gap between said divider walls.
Claim 8
Dependent Claim
20 words
A packing peanut as claimed in claim 6, wherein said divider transverse wall is flush with said shell flanged base.
Claim 9
Dependent Claim
20 words
A packing peanut as claimed in claim 6, wherein said divider transverse wall is offset axially from said flanged base.
Claim 10
Dependent Claim
29 words
A packing peanut as claimed in claim 8, wherein said divider transverse wall is axially offset from said flanged base approximately one fourth the axial height of said shell.
Claim 11
Dependent Claim
66 words
A packing peanut as claimed in claim 1, wherein said shell is of frustro-conical shape having an open end, wherein said integral radial flanged base is at said open end and having a conical side wall integral with said flanged base, tapering inwardly and terminating in an integral transverse top wall at an end remote from said base, closing off said hollow shell at that end.
Claim 12
Dependent Claim
19 words
A packing peanut as claimed in claim 10, wherein said shell side wall is of oval transverse cross section.
Claim 13
Dependent Claim
29 words
A packing peanut as claimed in claim 10, wherein said side wall includes a flute therein over the axial height of the shell and comprising said shape stability means.
Claim 14
Dependent Claim
33 words
A packing peanut as claimed in claim 10, wherein said conical shell side wall has a draft angle of from 5° to 15° and said flute has a draft angle of approximately 2°.
Claim 15
Dependent Claim

Claim 16
Dependent Claim
20 words
A packing peanut as claimed in claim 14, wherein said divider extends axially over approximately three fourth of said shell.
Claim 17
Dependent Claim
48 words
A packing peanut as claimed in claim 14, wherein said divider includes a pair of generally parallel laterally spaced walls forming a narrow gap therebetween and wherein said divider walls are joined by a transverse wall at ends remote from said shell top wall forming hinge connections therewith.
Claim 18
Dependent Claim
28 words
A packing peanut as claimed in claim 16, wherein said pair of divider walls include openings therein facing each other to reduce the weight of the peanut shell.
Claim 19
Dependent Claim
