Abstract
Abstract A pair of end cap members for containers such as luggage, and for furniture and the like are provided around their perimeters with internal facing U-shaped receiving and retainer slots. A unitary sheet contoured to form front, bottom and back panel portions are adapted to be received within the retainer slots. The panel portions are affixed by a bonding adhesive or the like within the U-shaped slots to form a complete unit.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
109 words
A rigid walled support structure comprising a pair of spaced rigid cap members of resinous material each selectively contoured to provide main rigid walled support panel portions each perimetrically bounded by a transversely extending wall portion defining corresponding internally facing U-shaped receiving and retainer slots; and an intermediate rigid walled unitary support body portion selectively contoured to define boundary portions which correspond to the main panel portions and having a predetermined portion of the terminal marginal edges of the body portion disposed within said receiving slots; said terminal marginal edges of said body portion being disposed within said U-shaped slots engaging the adjacent interfacial surfaces of said cap members.
Claim 2
Dependent Claim
109 words
A rigid walled support structure comprising a pair of spaced rigid cap members of resinous material each selectively contoured to provide main rigid walled support panel portions each perimetrically bounded by a transversely extending wall portion defining corresponding internally facing U-shaped receiving and retainer slots; and an intermediate rigid walled unitary support body portion selectively contoured to define boundary portions which correspond to the main panel portions and having a predetermined portion of the terminal marginal edges of the body portion disposed within said receiving slots; said terminal marginal edges of said body portion being disposed within said U-shaped slots engaging the adjacent interfacial surfaces of said cap members.
Claim 3
Dependent Claim
29 words
