Abstract
Abstract The packing elements are each formed with a hooked configuration so as to abut each other without interlocking with each other. The free ends of the two legs of each element project beyond the main body portions so as to impart a hooked effect to the elements. The elements can be poured from a hopper into a container.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
170 words
A loose fill free flowing packing material comprising a plurality of resilient thermoplastic elements, each said element having a substantially uniform thickness, a body portion having a first flat surface on one side and a second flat surface on an opposite side, a first leg extending integrally from one end of said body portion and passing through a plane of said first surface, a second leg extending integrally from an opposite end of said body portion and passing through a plane of said second surface, a first recess in said first flat surface adjacent said first leg, and a second recess in said second flat surface adjacent said second leg each leg being of a width at the end thereof greater than the width of a respective recess at the mouth thereof, each said leg being of decreasing width inwardly of said end thereof and each said recess being of increasing width inwardly of said mouth thereof to prevent each leg from fitting into a recess of a like element.
Claim 2
Dependent Claim
170 words
A loose fill free flowing packing material comprising a plurality of resilient thermoplastic elements, each said element having a substantially uniform thickness, a body portion having a first flat surface on one side and a second flat surface on an opposite side, a first leg extending integrally from one end of said body portion and passing through a plane of said first surface, a second leg extending integrally from an opposite end of said body portion and passing through a plane of said second surface, a first recess in said first flat surface adjacent said first leg, and a second recess in said second flat surface adjacent said second leg each leg being of a width at the end thereof greater than the width of a respective recess at the mouth thereof, each said leg being of decreasing width inwardly of said end thereof and each said recess being of increasing width inwardly of said mouth thereof to prevent each leg from fitting into a recess of a like element.
Claim 3
Dependent Claim
35 words
A loose fill packing material as set forth in claim 1 wherein each leg is of a width at the end thereof greater than the width of a respective adjacent recess at the mouth thereof.
Claim 4
Dependent Claim
24 words
A loose fill packing material as set forth in claim 2 wherein each said recess is of increasing width inwardly of said mouth thereof.
Claim 5
Dependent Claim
23 words
A loose fill packing material as set forth in claim 2 wherein each leg is of decreasing width inwardly of said end thereof.
Claim 6
Dependent Claim
24 words
A loose fill packing material as set forth in claim 4 wherein each said recess is of increasing width inwardly of said mouth thereof.
Claim 7
Dependent Claim
20 words
A loose fill packing material as set forth in claim 1 wherein each element is made of expandable thermoplastic material.
Claim 8
Dependent Claim
20 words
A loose fill packing material as set forth in claim 1 wherein each element is made of expanded thermoplastic material.
Claim 9
Dependent Claim
28 words
A loose fill packing material as set forth in claim 1 wherein each leg projects past a respective plane of said body portion a distance of one millimeter.
Claim 10
Dependent Claim
154 words
A loose fill packing element of resilient thermoplastic material, said element having a body portion with a first flat surface on one side and a second flat surface on an opposite side, a first leg extending from one end of said body portion through a plane of said first surface, a second leg extending from an opposite end of said body portion through a plane of said second surface, a first recess in said first flat surface adjacent said first leg, and a second recess in said second flat surface adjacent said second leg each leg being of a width at the end thereof greater than the width of a respective recess at the mouth thereof, each said leg being of decreasing width inwardly of said end thereof and each said recess being of increasing width inwardly of said mouth thereof to prevent each leg from fitting into a recess of a like element.
Claim 11
Dependent Claim
154 words
A loose fill packing element of resilient thermoplastic material, said element having a body portion with a first flat surface on one side and a second flat surface on an opposite side, a first leg extending from one end of said body portion through a plane of said first surface, a second leg extending from an opposite end of said body portion through a plane of said second surface, a first recess in said first flat surface adjacent said first leg, and a second recess in said second flat surface adjacent said second leg each leg being of a width at the end thereof greater than the width of a respective recess at the mouth thereof, each said leg being of decreasing width inwardly of said end thereof and each said recess being of increasing width inwardly of said mouth thereof to prevent each leg from fitting into a recess of a like element.
