Abstract
Abstract Sticks of foamable thermoplastic material are provided with grooves in at least one surface. These grooves extend width-wise of the stick. In addition, the grooves are disposed in equi-spaced relation along one surface of the stick, or in spaced-apart series or groups on only one surface, or in series or groups on opposite surfaces and in spaced-apart relation. Upon foaming, the sticks form formed elements of various shapes, each of which has at least one curvilinear portion such as, for example, a corkscrew shape, an annular shape or shapes with reverse bends.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
58 words
A foamed thermoplastic element having at least one curvilinear portion of substantially uniform cross-section shape disposed along a longitudinal axis, and further having a plurality of spaced apart spines projecting from at least one surface of said portion along a common line, said spines being angularly disposed relative to said longitudinal axis with a transverse component of direction.
Claim 2
Dependent Claim
58 words
A foamed thermoplastic element having at least one curvilinear portion of substantially uniform cross-section shape disposed along a longitudinal axis, and further having a plurality of spaced apart spines projecting from at least one surface of said portion along a common line, said spines being angularly disposed relative to said longitudinal axis with a transverse component of direction.
Claim 3
Dependent Claim
34 words
A foamed thermoplastic element as set forth in claim 1 wherein said spines are disposed at an acute angle to said longitudinal axis and said element is of a cork-screw configuration along said axis.
Claim 4
Dependent Claim
20 words
A foamed thermoplastic element as set forth in claim 1 wherein said spines are disposed perpendicularly of said longitudinal axis.
Claim 5
Dependent Claim
31 words
A foamed thermoplastic element as set forth in claim 1 wherein said spines are equi-spaced along said axis, and said axis follows a curvilinear path throughout the length of said element.
Claim 6
Dependent Claim
30 words
A foamed thermoplastic element as set forth in claim 1 having a spineless central section of straight configuration, and a pair of end sections of curvilinear configuration having said spines.
Claim 7
Dependent Claim
44 words
A foamed thermoplastic element as set forth in claim 1 having a first curvilinear section with spines on one surface and a second curvilinear section with spines on a surface opposite said one surface, said second section being reversely curved from said first section.
Claim 8
Dependent Claim
36 words
A foamed thermoplastic element as set forth in claim 1 wherein said spines project from one surface and are disposed in longitudinal and transverse rows along said longitudinal axis, and said element has an annular configuration.
Claim 9
Dependent Claim
68 words
A loose fill packaging material comprising a plurality of foamed thermoplastic elements, each said element having at least one curvilinear portion of substantially uniform cross-sectional shape disposed along a longitudinal axis, and further having a plurality of spaced-apart spines projecting from at least one surface of said portion along a common line, said spines being angularly disposed relative to said longitudinal axis with a transverse component of direction.
Claim 10
Dependent Claim
68 words
A loose fill packaging material comprising a plurality of foamed thermoplastic elements, each said element having at least one curvilinear portion of substantially uniform cross-sectional shape disposed along a longitudinal axis, and further having a plurality of spaced-apart spines projecting from at least one surface of said portion along a common line, said spines being angularly disposed relative to said longitudinal axis with a transverse component of direction.
