Abstract
Abstract A collapsible reel assembly is provided on which a length of wire, flexible tubing or the like may be wound. The assembly is formed of a pair of blanks made of corrugated fibreboard and each blank includes a hub portion, a rim portion spaced from and encompassing said hub portion, a plurality of annularly spaced first struts interconnecting the hub and rim portions, and a plurality of annularly spaced second struts, each of which has an outer end foldably connected to the rim portion. The first struts, and the rim and hub portions of a blank cooperate with one another so as to form an end wall for the reel assembly. The second struts of the blanks are transversely disposed relative to the end walls and cooperate with one another to form a core on which the length of wire, flexible tubing or the like is wound.

Claim 1
Independent Claim
323 words
A collapsible reel assembly comprising a pair of blanks interconnected to one another and arranged in substantially superposed relation, an intermediate member interposed said blanks, and a web of material removably disposed between said blanks and encompassing said intermediate member when said assembly is in a non-collapsed state; each blank including a hub portion, a rim portion spaced from and encompassing said hub portion, a plurality of annularly spaced first struts interconnecting said hub and rim portions, said first struts and said hub and rim portions of a blank defining an end wall of the reel assembly, and a plurality of annularly spaced second struts disposed intermediate said first struts and separated therefrom, each second strut being one end thereof foldably connected to a portion of the blank defining the end wall, and a second end thereof foldably connected to the second end of a corresponding second strut of the other blank of the assembly, corresponding second struts, when in a first position of adjustment, being in substantial endwise relation and forming a core section disposed intermediate said end walls and aligned with the hub portions thereof whereby said end walls are in substantially spaced, parallel relation and said assembly is in a non-collapsed state, and when in a second position of adjustment and said web has been removed from between said blanks, said second struts being disposed in proximate substantially parallel relation whereby said end walls and said intermediate member are in proximate substantially parallel relation and said reel assembly is in a collapsed state; and intermediate member including a central portion aligned with the hub portions of said blanks, and peripheral portions projecting from the central portion and extending between the adjacent second struts of said blanks, the outer periphery of said intermediate member supportingly engaging the encompassing web of material when said second struts are in said first position of adjustment and said reel assembly is in a non-collapsed state.
