Abstract
Abstract A corner pad for use in packaging fragile articles. The pad is formed from yieldable material and formed in a blank of solid rectangular configuration. It can be conveniently shipped and stored in this form. Immediately prior to use the blank is ''''popped'''' or setup for placement into engagement with the corner of the fragile article.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
224 words
A blank for use in padding a corner of an article comprising: a section of yieldable material having a first surface, a second surface parallel to said first surface, a thickness, t, between said first and second surfaces, a regular edge defining a plane perpendicular to said first and second surfaces, a transverse dimension perpendicular to said regular edge, and a longitudinal dimension parallel to said regular edge; a first interior separation through the entire thickness of said yieldable material and extending a distance less than said longitudinal dimension in a direction parallel to and spaced from said regular edge; a second separation in said first surface of said yieldable material including a substantial portion of said thickness and extending from said first interior separation to said regular edge; a third and fourth separation in said second surface including a substantial portion of said thickness of said yieldable material and extending from said first separation to said regular edge and spaced, respectively, an equal distance on opposite sides of said second separation; and a fifth separation including a substantial portion of said thickness of said yieldable material and extending from said first separation in a direction away from said regular edge, and adapted to allow folding of said section about an axis perpendicular to said regular edge midway between said third and fourth separations.
Claim 2
Dependent Claim
224 words
A blank for use in padding a corner of an article comprising: a section of yieldable material having a first surface, a second surface parallel to said first surface, a thickness, t, between said first and second surfaces, a regular edge defining a plane perpendicular to said first and second surfaces, a transverse dimension perpendicular to said regular edge, and a longitudinal dimension parallel to said regular edge; a first interior separation through the entire thickness of said yieldable material and extending a distance less than said longitudinal dimension in a direction parallel to and spaced from said regular edge; a second separation in said first surface of said yieldable material including a substantial portion of said thickness and extending from said first interior separation to said regular edge; a third and fourth separation in said second surface including a substantial portion of said thickness of said yieldable material and extending from said first separation to said regular edge and spaced, respectively, an equal distance on opposite sides of said second separation; and a fifth separation including a substantial portion of said thickness of said yieldable material and extending from said first separation in a direction away from said regular edge, and adapted to allow folding of said section about an axis perpendicular to said regular edge midway between said third and fourth separations.
Claim 3
Dependent Claim
13 words
The blank of claim 1 wherein said fifth separation includes said second surface.
Claim 4
Dependent Claim
30 words
The blank of claim 2 wherein said third and fourth separations are spaced, respectively, a distance in the range of 1t to 2t on opposite sides of said second separation.
Claim 5
Dependent Claim
26 words
The blank of claim 3 and adhesive disposed on said second surface between said regular edge, said first separation, said second separation and said third separation.
Claim 6
Dependent Claim
19 words
The blank of claim 4 and adhesive disposed on said first surface on opposite sides of said fifth separation.
Claim 7
Dependent Claim
22 words
The blank of claim 1 wherein said fifth separation includes said first surface and diverges from said axis to said first surface.
Claim 8
Dependent Claim
23 words
The blank of claim 6 wherein said fifth separation defines diverging undulations disposed to mesh upon folding of said section about said axis.
Claim 9
Dependent Claim
30 words
The blank of claim 6 wherein said third and fourth separations are spaced, respectively, a distance in the range of 1t to 2t on opposite sides of said second separation.
Claim 10
Dependent Claim
26 words
The blank of claim 8 and adhesive disposed on said second surface between said regular edge, said first separation, said second separation, and said third separation.
Claim 11
Dependent Claim
19 words
The blank of claim 9 and adhesive disposed on said second surface on opposite sides of said fifth separation.
