Abstract
Abstract A weatherproof system for cargo containers has therein an outwardly open lengthwise channel or groove formed in each of two opposing side edges of a floor panel 1, and the lower portion of one of four side panels is disposed immediately outward of the groove in such a way that a water trapping chamber is defined between the lengthwise groove and the lower portion of the side panel. The bottom surface of the water trapping chamber thus defined is in substantially coplanar relationship with an adjacent seat surface which supports thereon the bottom edge of each of the side panels, and the upper wall of the water trapping chamber is extended outwardly so as to define a water drip or barrier means. Therefore, rain or sea water flowing along the intersurface between the floor panel and each of the side panels is entrapped in the water trapping chamber and consequently prevented from further flowing into the interior of the container.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
142 words
A cargo container comprising: floor means having seat means formed along at least some of side edges thereof; upright side panel means having bottom edges, respectively, at least some of the bottom edges being seated respectively on said seat means to form a box-shaped container chamber with the top opened; roof means closing the top; and means forming a water trapping chamber along each of said some side edges of the floor means, said chamber extending lengthwise of each side edge and opening outwardly, said chamber being closed substantially by the lower portion of one of the side panel means which is disposed immediately outward of the chamber, and having a bottom surface in substantially coplanar relationship with one of the seat means, said chamber having a top surface extending outwardly and transversely to the chamber to form a water barrier means.
Claim 2
Dependent Claim
142 words
A cargo container comprising: floor means having seat means formed along at least some of side edges thereof; upright side panel means having bottom edges, respectively, at least some of the bottom edges being seated respectively on said seat means to form a box-shaped container chamber with the top opened; roof means closing the top; and means forming a water trapping chamber along each of said some side edges of the floor means, said chamber extending lengthwise of each side edge and opening outwardly, said chamber being closed substantially by the lower portion of one of the side panel means which is disposed immediately outward of the chamber, and having a bottom surface in substantially coplanar relationship with one of the seat means, said chamber having a top surface extending outwardly and transversely to the chamber to form a water barrier means.
Claim 3
Dependent Claim
24 words
A cargo container as claimed in claim 1, further comprising a jaw-like means projecting dependingly from the outer edge of said water barrier means.
Claim 4
Dependent Claim
31 words

A cargo container as claimed in claim 1, further comprising a sealing frame securely joined to the bottom edge portion of each of said side panel means and placed into intimate contact with the associated seat means.
Claim 6
Dependent Claim
64 words
A cargo container as claimed in claim 1, further comprising an upper sealing frame securely joined to the upper edge portion of each of the side panel means, and a sealing beam securely attached to the roof means along each of the side edges thereof and placed into intimate contact at the bottom thereof with an upwardly directed surface of the upper sealing frame.
Claim 7
Dependent Claim
80 words
A cargo container as claimed in claim 1, further comprising a sealing frame securely joined to each of the side edges of each of the two opposing side panel means forming a first pair, and a resiliently yieldable corner post means securely joined to each of the side edges of each of the other two opposing side panel means forming a second pair, said sealing frame and said corner post means being partially overlapped and resiliently pressed against each other.
