BOX (10., OF CAMBRIDGE, MASSACHUSETTS, A CORPORATION OF msseonusnrrs BOX Am)- covname BLANK THEREFOR Application filed April 4, 1929. Serial No. 352,542.
This invention aims to provide an im-' proved covered box, the invention being principally exemplified in a box of which the covering is paper.
.5 It has long been common to manufacture boxes rectangular in shape and composed of a box proper or body portion of pasteboard suitably formed to present a bottom with upstanding side walls and wherein the covering paper has been applied automatically by machinery, as well as by hand, but, so far as I am aware, no box of octagonal, hexagonal or other shape, having obliquely arranged side walls, has ever been successfully covered 15 by machinery. Such boxes have been made by hand, whereinthe covering member could be carefully worked about and infoldedagainst the'upstanding side walls of the box body, but the limitations of machinery operation; have been such as to make it impracticable in attempts, so far ,known to me, to cover such boxes by machine.
' -My invention provides a box that may be successfully covered by machine as well as hand. My invention comprises a box and its covering blank having novel shape andapplied in novel manner, as will be best understood from a description of one illustrative embodiment of my invention, shown in the accompanying drawings. 1
Referring to the drawings Fi 1, in perspective, shows an octagonal box ustrating my invention;
5 r Fig. 2 showsia covering blank before application to the box body; and
Fig. 3 shows a perspective illustrating the I manner of applying the covering blank to the body. f
Referring to the drawings, in the particular illustrative embodiment of my invention there shown, the. box body or box proper, made of suitable material as, for example, ordinary pasteboard or strawboard, has a bottom 1 provided with upstanding side walls, 2, 3 and 4, best shown perhaps in Fig. 3.
The boxbody may be formed in any suitable manner, but is commonly made by upturning the projecting portions of a blank and, when necessary, securing the same at the corners or by an encircling band.
The covering blank, usually of paper, but which, so far as my invention is concerned, may be made of any suitable material, and generally denoted by the reference letter C, comprises a central portion 5, see Fig. 2, from which radiate or project flaps 6, 6, 7, 7, 8 and 8. These flaps, as will be observed, are arranged diametrically opposite each other in pairs. The flaps 6, 6, are provided at their side edges with wings 9, shown as irregular in outline, and presenting a gradual taper from their outermost extremities to a little more than half the distance to their bases, where the angular direction at 10 is sharply changed and made more acute at 11 to the bases of the flaps. This change of angular direction in the edges of the wings at 10 brings the wing more quickly and fully around the corner about which it is folded, and makes for a much more complete covering of the underlying box body or box wall than is possible were the wing to have a straight edge extending obliquelyv outward from its base to its top. The opposite flaps 7, shown as extending generally at right angles to the direction of ,the lengths of the flaps 6, have their side edges straight at 12, and tapering inwardly from their bases to their outer extremities. The intermediate flaps 8, which in the shape of box shown are four in number, there being two pairs, each have one of their edges 13 provided with win s corresponding to the wings of the flap 6, w liile their other edges are straight and inwardly inclined from the bases to the outer extremities thereof at 14, after the manner of the side edges 12 of the flaps 7. In each instance it will be observed that a winged flap ed e is opposed by a tapering straight edge.
assemblin the box, the pasted blank is placed upon a body with the pasted surface uppermost, and the box is placed accurately thereon, with the 'outer surface of the bottom 1 centered upon the middle area v 5 of the blank, and with the bases of the several upturned side walls of the box evenly positioned across the base lines of the several outwardly projecting flaps.
against the sides 2 of the box, as indicated in I a binding 15 extending entirely around the v Fig. 3. The wing portions 9 are then folded about andinwardly against adjacent portions of the oblique or diagonal side walls 4.
Next the diagonally arranged pairs of flaps 8 are upturned against the walls 4, 4, of thebox, the straight edges14 of said diagonal flaps overlapping the infolded wings 9 of the flaps 6 and, in turn, the winged edges 13 of said diagonal flaps being overlaid upon and against the adjacent portions of the side Walls 3 of the box. Finally, the straight tapered-edge flaps 7 areupturned and pressed against the sides 3 of the box, and overlying and partially covering the infolded wings 13 of the diagonal flaps When the several flaps have been upturned and thus folded inward against the box sides and the underlying flap wings infolded against the said box, the upwardly projecting extremities of the several flaps are folded inward and .downward upon the inner faces of the several side walls of the box, to forth edge ofcthe box Wall.
Thus the completed box presents two op posite walls, the coverings of which extend beyond the limits of the walls and are infolded against adjacent portions of the infolding Walls; at least two other walls are covered by upturned flap portions that have one of their edges extended in infolded wing form about and upon adjacent portions of adjoining walls, while their other edge portions overly the wing portions. of the other flaps upturned, and-finally a pair of flaps that do not wholly cover the walls against which they are upturned and pressed, but present straight tapering and gradually contracting edges extending from the bottomto the top'edge of the wall.
Such a box may be covered by adaptations of commercial machines, by reason of the A use of the intermediate diagonally arranged flaps provided respectively with one winged edge and one straight tapering edge.
The number of pairs of intermediate flaps will be varied according to the number of oblique sides to the box 1, but, in any event, a blank for a box having an even, number of pairs of sides will be provided with one pair of flaps, both edges of which will be winged, to be first upturned and iufolded, one pair of flaps having straight tapering edges to receive the final upturning and infolding operation, and as many intermediate flaps with the necessary arrangement of combined winged and straight tapering edges as may be necessary to accommodate the shape of boxes to be covered.
The cover for the box of course would be handled in a manner similar to the bottom portion'or box proper, and no separate illustration is required.
Where the box is composed of an odd number of pairs of sides or an odd number of sides, lacking a pair in any given parallel outwardly extended flaps as there arebox 7 sides, one or-more of said fla s initially upturned having both their e ges winged to overlap adjacent portions of adjoining box Walls, at least one of said flaps for final upturning having both edges inwardly tapering, and at least one intermediate flap provided with one winged and one tapering edge covering sa1d box proper and the walls thereof.
2. A covered box comprisin a box proper having a bottom and at least t ree upturned side walls extended in different directions, and a box covering comprising a blank applied to said bottom and with as many outwardly extended flaps as there are box sides,
at least one of said flaps initially upturned having both edges winged to overlap adjacent portions of adjoining box walls, at least one of said flaps for final upturning having both edges inwardly tapering, and at least one intermediate flap provided with one winged and one tapering edge covering said box proper and the walls thereof, and infolded about the upper edges of the box wall to constitute a. binding therefor.
3. A covered box comprising a box proper having a bottom and at least three pairs of upturned side walls, one of said pairs being obliquely arranged with respect to the remaining pairs, and a box covering comprising a blank applied to said bottom and with as many pairs of oppositely extended flaps as there are pairs of box sides, one pair of flaps being winged at both of their edges and upturned against two of the box walls, and with their wings infolded against adjacent portions of adjoining box walls, another pair of flaps having one of their edges winged and the other inwardly tapering upturned against other box walls, and a third pair of flaps, both the edges of which are inwardly tapering and 4:. A covered box comprising a box proper having a bottom and four pairs of upturned slde walls, two of said pairs being obliquely arranged relative to the remaining pairs, and

and the remaining pair of aps having taper; ing edges finally upturned and infolded against the last remaining pair of box walls,
and over and upon the infolded wings of previously folded flaps. I
5. A; covered box comprising a box proper having a bottom andfour pairs of -upturned side walls, two of said-pa irs being obliquely arranged relative tothe remaming palrs,

flaps having tapering edges finally upturned and infolded against the remaining pair of, box walls, and over and upon' the infolded wings of previously folded flaps, and with the extreme flap extremities infolded over the box walls and upon the inner faces of th latter, to furnish a. binding therefor.
6. A covered box comprising a box proper having a bottom and upturned side 'walls, and a covering therefor comprising a central portion with radiating flaps, at least one of which has winged edges, another of which has one winged side edge and one inwardly.
tapering side edge, and a third having bot edges inwardly tapering.
Tn testimony whereof I have signed my name to this specification.
