Abstract
ABSTRACT
An improved coil package comprises a closable carton formed from a folded blank of cardboard and, removably housed in the carton, a reel on which is carried a coil of wire. A hollow hub formed of a transversely folded metal strip extends between and is secured with respect to the reel flanges. Each reel flange is secured to the inner face of, or is restrained against movement in a direction away from and against rotational movement about its axis with respect to, the adjacent major side wall. Where the reel flanges are secured to the inner faces of the major side walls, boundaries between the major side walls and an outer peripheral wall are perforated to facilitate removal of the outer peripheral wall.

AN IMPROVED COIL PACKAGE
This invention relates to the packaging of wire or cable and more particularly to the packaging of coils of bare or insulated electric wire or cable, for example wire or cable of the kinds used in house wiring systems, all such bare and insulated wire and cable hereinafter, for convenience, being included in the generic term "wire".
By a "coil" of wire is meant a self-supporting multiplicity of turns or convolutions of wire.
The interests of the manufacturer, wholesaler or retailer, and user of wire are in conflict insofar as transportation and packaging of wire are concerned. For ease of manufacture and transportation within the factory, it is in the interests of the manufacturer that wuire used within the factory be in coil form. From the point of view of the wholesaler or retailer who has to - keep a large stock of wires of different kinds from one another, storage of wire is facilitated if it is supplied in packages of a shape and size such that they can be readily stacked. On the other hand, the user prefers wire to be supplied on a reel from which wire can be readily unwound as and when required. Generally, wire is marketed either in coils which are covered by a toloidal lapping of paper or cheap fabric or on non 25- returnable reels. The former type of packaging is cheap but it is not popular with wholesalers and retailers ' g .. . . . . . . .,, . . . _ _ .. _ . .. . . .. .. . .... . . .

because such packaged coils are not readily stackable and is not popular with users because wire cannot be readily withdrawn from a coil and because once the toroidal lapping is removed to enable wire to be withdrawn from the coil, the balance of the coil is left unprotected and may become tangled, as replacement of the toroidal lapping is usually too tiresome to be undertaken by the user. The alternative form of packaging in non-returnable reels is unpopular with the wire manufacturer because it is more labour intensive and costly and i9 disliked by the wholesaler and retailer because reels cannot be readily stacked.
Several forms Or wire packages have been proposed that serve the dual purpose of a container or carton for a coil and of a reel from which wire from the coil can be readily withdrawn but all suffer from the disadvantage that they are not easily stacked for storage purposes and/or, once the container or carton has been opened to withdraw wire from the coil, are not readily re-closed for the purpose of protecting that part of the coil remaining in the package.
It is the object of the present invention to provide an improved coil package which serves the dual purposes of a coil carton and a reel, which is simple and inexpensive to manufacture and which provides for ready removal and-replacement of the carton.

3 20143-769 According to the invention our improved coil package com-prises a closable carton which is formed from at least one folded blank of cardboard or plastics material and which has a pair of oppositely disposed major side walls, each of which major side walls has an aperture in substantially axial alignment with the aperture of the other major side wall; a pair of separately formed substantially flat reel flanges, each of which reel flanges is adjacent to the inner face of, and is restrained against movement in a direction away from and against rotational movement about its axis with respect to, one of the major side walls and each of which reel flanges has an aperture in substantially axial alignment with the apertures of the major side walls; a coil of wire positioned between and bounding the apertures in the reel flanges; and, extending between parts of the reel flanges bounding said aligned apertures and secured with respect to the reel flanges, a substan-tially rigid hollow hub.
Since the reel flanges constitute component parts of the coil package and serve to strengthen its major side walls, the improved coil package has the important advantage that the carton can be formed of a cardboard or plastics material or a thickness such that it can be readily folded.
When the coil of wire substantially fills the carton the coil of wire will itself, at least in part, serve to restrain move-ment of each reel flange in a direction away from its associated major side wall but, in the preferred improved coil package, each reel flange is restrained against movement in a direction away from its associated major side wall irrespective of the quantity of wire .~
