Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
49 words
An intermodal freight container comprising a metallic frame, and panels adhesively bonded to said frame, each panel comprising a core of plywood and the like encapsulated in a fibrous glass reinforced plastic, said adhesive bond having limited elasticity to permit flexure of the total system while retaining its integrity.
Claim 2
Dependent Claim
49 words
An intermodal freight container comprising a metallic frame, and panels adhesively bonded to said frame, each panel comprising a core of plywood and the like encapsulated in a fibrous glass reinforced plastic, said adhesive bond having limited elasticity to permit flexure of the total system while retaining its integrity.
Claim 3
Dependent Claim
21 words
A container as set forth in claim 1 including a polyurethane adhesive bonding said panels to each other and said frame.
Claim 4
Dependent Claim
35 words
A container as set forth in claim 2 including a butt joint between adjacent panels with thin metallic bond strips covering such butt joint and bonded by such adhesive to the faces of adjacent panels.
Claim 5
Dependent Claim
