Abstract
Abstract A container for a wire spool adapted to be stacked one on top of the other without damage thereto or to its contents. The container comprises a spool housing having a side wall, a bottom wall and an open top end. A cover is provided for the open top end and is engageable about an outer peripheral edge of the open top end. A cover having load transfer ribs converging into a ring which is formed therein and which extends within the housing. The load transfer ring rests on an upper end of a wire spool, when provided in the housing, whereby external loads on the cover will be transmitted to the bottom wall of the housing through the load transfer ring and a core of the spool.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
180 words
The combination of a spool for metal wire and the like and a container for said spool; said spool having a core and upper and lower flanges at the opposite ends thereof; said container comprising a housing and a removable cover; said housing having a side wall, a bottom wall and an open top end; said spool being disposed entirely within said housing with said lower flange being seated on said bottom wall, said upper flange being recessed below the housing top end; said cover closing said housing open top end and including a depending wall having a portion in sealing sliding engagement with the exterior of said housing side wall defining a floating joint between said cover and said housing permitting vertical displacement of said cover relative to said housing while frictionally engaging said housing to accommodate spools of different heights; and said cover having load transfer means depending into said housing and being directly seated on said upper flange with said spool directly transferring loads between said cover and said bottom wall independently of said housing side wall.
Claim 2
Dependent Claim
180 words
The combination of a spool for metal wire and the like and a container for said spool; said spool having a core and upper and lower flanges at the opposite ends thereof; said container comprising a housing and a removable cover; said housing having a side wall, a bottom wall and an open top end; said spool being disposed entirely within said housing with said lower flange being seated on said bottom wall, said upper flange being recessed below the housing top end; said cover closing said housing open top end and including a depending wall having a portion in sealing sliding engagement with the exterior of said housing side wall defining a floating joint between said cover and said housing permitting vertical displacement of said cover relative to said housing while frictionally engaging said housing to accommodate spools of different heights; and said cover having load transfer means depending into said housing and being directly seated on said upper flange with said spool directly transferring loads between said cover and said bottom wall independently of said housing side wall.
Claim 3
Dependent Claim
58 words
The combination of claim 1 wherein said load transfer means is in the form of a hollow ring having a flat lower end seated on said upper flange, and said bottom wall has a depending support rim of a size and position for seating in the hollow ring of an underlying cover and assuring alignment of stacked containers.
Claim 4
Dependent Claim
25 words
A combination as claimed in claim 2 wherein an outer support flange is provided in said bottom wall and disposed concentrically about said support rim.
Claim 5
Dependent Claim
50 words
A combination as claimed in claim 1, wherein said peripheral floating joint is formed by a peripheral vertical end wall of said cover, said end wall having a friction member for frictional engagement with said peripheral portion of said top end of said side wall adjacent said open top end.
Claim 6
Dependent Claim
75 words
A combination as claimed in claim 4, wherein said top end of said housing has a cover engaging rim, said friction member being an annular friction rib displaceable about said peripheral portion of said housing side wall below said engaging rim whereby said engaging rim limits upper vertical displacement of said cover and frictionally engages an inner face of said peripheral vertical end wall to constitute a double friction seal with said annular friction rib.
Claim 7
Dependent Claim
84 words
A combination as claimed in claim 4, wherein one or more vertical aligning slots are provided in said outer peripheral edge of said open top end, and one or more cover alignment ribs extending perpendicular to the planar axis of said cover from said peripheral vertical end wall thereof, said one or more cover alignment ribs extending into a respective one of said one or more vertical aligning slots when said cover is engaged about said outer peripheral edge of said open top end.
Claim 8
Dependent Claim
88 words
A combination as claimed in claim 6, wherein said cover is provided with diametrically opposed hand hole cavities each having a cavity bottom wall to engage at an outer peripheral edge with an inner surface of said side wall of said spool housing below an associated hand hole of two hand holes diametrically opposed in said side wall spaced from said outer peripheral edge of said open top end, said aligning slots and alignment ribs positioning said hand hole cavities adjacent a respective one of said hand holes.
