2 Claims. 7 1
The present invention relates to a container for articles having circular disc configuration and is concerned particularly in a unique packaging device which may be economically produced.
Circular saws have for a considerable period of time presented a problem in connection with their packaging for individual sales and transportation. The principal difiiculty arises from the fact that the periphery which may be comprised of various classes of teeth must be kept Well protected against dulling and abrasion in order to maintain the maximum efiiciency of the product during transit. Again the saw blade requires a considerable amount of protection while in the possession of the user and towards this end the present improvement contemplates a packaging container-which will not only afiord safety during transportation or shipment, but which will in addition be a serviceable container for use by the ultimate consumer in protecting the saw against exposure and inadvertent damage resulting from careless handling. Accordingly a principal object of the present invention is to devise a means of packaging circular saw blades which will afford adequate protection during transportation and handling and which may be formed from a minimum of stock material under conditions of low wastage during formation and such as will afford maximum efficiency during packaging assembly.
For a more comprehensive understanding of the present invention reference will now be had to the accompanying drawings and to the following detailed specification in which like reference characters designate corresponding parts through and in which:
Fig. 1 is a plan view of an improved packaging device in which a circular saw blade has been installed, with portions broken away to reveal posterior structure;
Fig. 2 is an elevation of the package featured in Fig. 1 showing all of the flaps folded and the latching tab in position ready for shipment;
Figs. 3, 4 and 5 are plan elevations illustrating progressive steps in the tab folding operations preparatory to the achievement of the folded condition featured in Fig. 2;
Fig. 6 is a plan view of the packaging material in which the tabs are incised but remain in the non-folded condition; and
Fig. '7 is a plan view of a continuous web of stock illustrating the manner in which the packaging material may be incised and out under conditions of minimum wastage.
Referring now more particularly tothe accompanying drawings, the reference character H designates a circular saw blade which may be of anydesired class, but which has been illustrated as one of the combination rip and crosscut pattern. Each container blank is preferably proportioned to accommodate a particular size of circular saw blade since standard practice customarily provides for saw blades to be made within predetermined ranges of diameter. The principal panel of the package, designated I2, Fig. 6, is octagonal in outline with each of its eight sides preferably having equal length so that the teeth of the saw blade l -may-beafiorded throughout engagement circumferentially with the respective narrow defining areas designated 13 and Id.
The areas l3 and M are preferably double scored-so as to provide a thickness to the package commensurate with average blade thickness. Alternate fringe panels l5, [6, IT and I8 are cut so as'to have rectangular conformation, while the intermediate fringe panels I9, 21, 22 and 23 are trapezoidal shape.
Three of the rectangular fringe panels [5, l6 and [8 are approximately of equal areas while the remaining rectangular fringe panel I! is somewhat longer and is provided with a large opening 24 spaced and conformed to aline with the central opening 25 of the principal panel I2. In addition to this the longer fringe panel l! is also provided with a grommet or hollow rivet 26 securely imbedded and having adjunct to it, a foldable retainer tonguel'l, Fig. 2.
The location of the tongue 21' is such that when the container blank is folded into the condition illustrated in Fig. 2, the tongue 21 will enter through a hollow rivet or grommet 28 installed in the diametrically opposite rectangular tab l5, Fig. 6. Accordingly the sole perforations required in accordance with the formation of the herein described container blank are those to accommodate the grommets 26 and 28 and the central openings 24 and 25.
In the formation of the container blank as indicated in Fig. 7, cut-out die edges are required for the formation of the openings as aforementioned and for the formation of the fringe panels l5 through 23 as already described. Scoring die edges are required for the formation of the fold lines which define the narrow areas l3 and I4. By arranging the pattern in the manner illustrated in Fig. 7, material scrap may be confined to the small triangular panel 29 and the trapezoidal panel 3|, thereby reducing to a minimum the essential scrap where the pattern is struck from a single web. By compounding or over-lapping j the cut-outs so as to provide for multiple row strikings even these scrap areas may be further limited, as will appear, since a secondary row may be produced in contiguous formation with practically no intervening scrap. The cut-out forms, Fig. 6, may be conveniently stacked and stored preparatory to usage since they occupy but a single thickness and include an overall area but marginally greater than the area of the saw blade which they are to enclose. The proportion of the fringe panels I5 to 23 is recommended to be at approximately the ratio to the center panel l2 as that indicated in Fig. 6. Under such conditions, when the saw blade is placed in position the teeth thereof will be presented tangentially to each one of the narrow areas 53 and I4, as may be discerned from Fig. 3.
The procedure for folding this container is, first, to fold over on their scored fold lines the trapezoidal fringe panels l9 and 22, then the transversely disposed trapezoidal fringe panels 2! and 23. Thereafter the rectangular fringe panels l6 and I8 are folded over and finally the rectangular fringe panels [5 and ill in the order designated. Following this the grommet tongue 21 is inserted into the hole 28 of its opposing panel 15 and folded over as indicated in Fig. 2.
The resulting package will appear as illustrated in Fig. 2 and the saw blade will be securely held by tangential pressure of the areas 13 and I4 against its teeth. The multiple overlapping thicknesses of the panels 55 to 23 afiord ample side cushion protection to the saw blade and, in addition to this, the octagonal points 35 provide a degree of safety should the package be dropped on its edge since under all conditions other than by falling sharply on a fiat outer edge of the areas 13 and H8, in other words, by falling on one of the points 35, which condition is vastly more probable, injury to the saw edges is minimized by the cushioning effect which Will result from the partial collapse of the folded outer point 35.
By means of the packaging assembly thus described there is not only afforded a stout protective enclosure which may serve during shipment of the article, but upon subsequent usage and reusage in connection with this type of protective package, a saw blade may be prevented from exposure to dust and moisture, as is frequently prevalent in sheds and basements where amateur users are likely to store such tools. Furthermore, the package may be filled with hard oil or any other rust inhibiting material and be retained thereby under ideal protective conditions.
While the present invention has been explained and described with reference to a specific embodiment and pattern of container blank, it will be understood nevertheless that numerous changes and modifications may be invoked without departing from the essential spirit or scope thereof. Accordingly it is not intended to be limited by the details illustrated in the accompanying drawings, nor by the specific language employed in the foregoing description, except as indicated in the hereunto appended claims.
The invention claimed is:
1. In a container for a fragile disk, a structure formed of a single fibrous board profiled to afford a symmetrical polygonal center panel having an even number of sides, at least six in number, and a plurality of radially extending fringe panels, said center panel being of an area to encompass the disk to be packaged so that its polygonal sides are tangential to the circumference of said disk, the fringe panels being on continuous fold lines and comprising alternate rectangles and trapezoids completely surrounding the center panel, said trapezoidal panels and its adjacent rectangular panels being of such areas and angularity that, when a trapezoidal panel is folded in overlapping relation to the center panel, it will cover a corresponding section of said center panel bounded by three sides of the center panel which form boundaries respectively between the center panel and said trapezoidal panel and its two adjaeent rectangular panels, said overlapped portion of the center panel being substantially a replica of said trapezoidal panel, and securing means on a pair of opposed rectangular fringe panels whereby, upon being last folded over, said pair of fringe panels effect retention of the other fringe panels.
2. A container as defined in claim 1 which is in the form of an octagon.
