Abstract
Abstract A knock-down reusable shipping container includes completely separable top, base, end and side walls and fastener means whereby adjoining corners of the separable walls may be securely fastened in assembled relationship and quickly separated. Spring clip fasteners cooperate with reinforcing plates on the respective container walls to produce one way and two way corner connections. Economy of manufacture and minimized labor in the use of the invention are featured.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
248 words
In a knock-down reusable shipping container having separable panels adapted to be assembled into a rectangular box form, plural separable fastener assemblies for pairs of said panels which define right angular corners on the shipping container, each separable fastener assembly comprising a coacting pair of reinforcing plates and means to secure said reinforcing plates fixedly on the outer faces of said panels forming a right angular corner, each reinforcing plate having an integral right angular flange on one end thereof lapping the adjacent edge of the panel on which the reinforcing plate is mounted, whereby said flanges resist movement of the reinforcing plates by abutment with said panel edges, each reinforcing plate of the fastener assembly having a substantially central opening formed therethrough and said opening having at least one straight edge, the straight edges of the two reinforcing plate openings being substantially parallel in the fastener assembly, the adjacent pair of panels having clearance recesses formed in their outer faces in registration with the reinforcing plate openings, and a substantially right angular spring sheet metal clip adapted to span the container corner on the exterior faces of said reinforcing plates and having opposite end locking terminals projecting inwardly from the arms of said clip and having interlocking engagement with said straight edges of the reinforcing plate openings, said panel clearance recesses receiving said clip locking terminals and allowing insertion of a clip separating blade through one of said reinforcing plate openings and into the adjacent panel recess.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
47 words
The structure of claim 1, wherein said reinforcing plate openings are square and of a width only slightly greater than the width of said clip so that the latter when in place on the container cannot shift laterally in either direction relative to the associated reinforcing plates.
Claim 4
Dependent Claim
36 words
The structure of claim 2, and said clip locking terminals comprising generally S-shaped terminals on the ends of the clip arms which snap over and lock beneath said straight edges while projecting into the clearance recesses.
