Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
209 words
In a material handling crate having integrally molded plastic sidewalls and reinforcing means on said sidewalls adjacent the open top of the crate, the improvement wherein said reinforcing means comprises an endless metal ring mounted on and extending around said crate adjacent the open top thereof and having an exposed upwardly directed surface defining at least a portion of the top rim surface of the crate, and retaining means supporting said reinforcing ring in position on said crate, said retaining means including an integrally molded substantially horizontal flange extending around said crate adjacent the open top thereof defining a substantially horizontal ledge positioned to engage and support a downwardly directed surface of said metal ring, said horizontal ledge being capable of transmitting vertical loads from said metal ring to said sidewalls, a band extending upwardly from said flange and cooperating therewith to define a shoulder, and means interlocking said retaining means and said metal ring including a plurality of openings extending through said band at spaced intervals around said crate and a plurality of integrally formed tab portions on said reinforcing ring extending through said openings and cooperating with said flange and said band to prevent substantial relative movement between said metal ring and said sidewalls of said crate.
Claim 2
Dependent Claim
209 words
In a material handling crate having integrally molded plastic sidewalls and reinforcing means on said sidewalls adjacent the open top of the crate, the improvement wherein said reinforcing means comprises an endless metal ring mounted on and extending around said crate adjacent the open top thereof and having an exposed upwardly directed surface defining at least a portion of the top rim surface of the crate, and retaining means supporting said reinforcing ring in position on said crate, said retaining means including an integrally molded substantially horizontal flange extending around said crate adjacent the open top thereof defining a substantially horizontal ledge positioned to engage and support a downwardly directed surface of said metal ring, said horizontal ledge being capable of transmitting vertical loads from said metal ring to said sidewalls, a band extending upwardly from said flange and cooperating therewith to define a shoulder, and means interlocking said retaining means and said metal ring including a plurality of openings extending through said band at spaced intervals around said crate and a plurality of integrally formed tab portions on said reinforcing ring extending through said openings and cooperating with said flange and said band to prevent substantial relative movement between said metal ring and said sidewalls of said crate.
Claim 3
Dependent Claim
36 words
In the material handling crate defined in claim 1, the further improvement wherein the top edge surface of said band and said exposed upwardly directed surface cooperate to define the top rim surface of said crate.
Claim 4
Dependent Claim
41 words
The material handling crate deFined in claim 1, wherein said band extends upwardly from the outer peripheral edge of said flange to define said shoulder for supporting said reinforcing ring around the inner periphery at said crate at said open top.
Claim 5
Dependent Claim
52 words
The material handling crate defined in claim 3, wherein said openings extend horizontally through said band and said tabs project outwardly from the outer peripheral surface of said reinforcing ring in position to project one through each of said openings to prevent said reinforcing ring from being lifted vertically from said shoulder.
Claim 6
Dependent Claim
55 words
The material handling crate defined in claim 1, wherein said band extends upwardly from the inner peripheral edge of said flange to define said shoulder for supporting said reinforcing ring around the outer periphery of said crate at said open top, said band forming in effect a vertical continuation of said sidewalls above said flange.
Claim 7
Dependent Claim
88 words
The material handling crate defined in claim 5, wherein a portion of said openings are extended horizontally through said band and a portion extend vertically through said flange, said reinforcing ring having a portion of said tabs extending inward from the inner peripheral surface thereof to extend through said openings in said band to prevent vertical movement of said reinforcing ring and a portion of said tabs extending downward through said openings in said flange to prevent said sidewalls from being deflected inward relative to said reinforcing ring.
