VBe 1t known that we, XVARREN B.-I:l0\\E n and FRANK B. DAVIDSON, of Chicago, inthe county of Cook and State of I llinois, have ini vented certain newgmd useful Improvements in Peper Boxes; and we' do hereby declare. that the following is el full, clear, and exact 4 Y description thereof, referenee'heing hadto the `mreompanyrig drawings, and to the/letters of reference marked thereon, which form a. part of this spooitiction. 'A

Onrinvention'relates to improvements in paper boxes or cartons of that class in which the side wallsare provided et their edges with integral flaps which vinterlock to yform the.

l end ofY the box, the whole being adapted to knock down 4 or fold f l'at when such inter- 4 locking flaps are disengaged.'

The object of the in vention is to provide au I improved construction in primer boxes of the class referred to, and to this end it consistsin the matters hereinafter described and prtichlarly pointed out in the appended claims.

" Our xmprovementsare especially applica.`

l bie to sector-shaped boxes used in pack-ing seine kinds of merchandise, forxsmple, stick in buckets, poils, bar# tionof' which renders it necessary thatv the y0 boxe'stobefpacked therein should be sector.-

shaped in order that there may be no loss of are side however, mustapproximete 'a curve and to' this end is usually'eomposedof s plurality of sections made V,standing in the same .relation tothe theoretical arco! theseetor that the sides of a. regulu polygon. .do to the For example, in one sector-shaped box h retoforernade the sroside of theliox is mde np of three sections,zthe center one of lwhich carries the tuck for securing thejlapsbforming the end o1"` the box. This box, however, cannotl be collapsedy and laid flat for packing and shipment in knock-down form with'.

'. viously reinlering` the box less rigid and-op- `erating to materially'lweaken the' tuck.

other'timn' 'those 'necessarily occurring et the more sim'pe and better-construction and orraugement are rendered possible.

Our improvements are also applicable, however, to ,other foxmsof knock down paper box or carton besides that 'hereinabove referred to, as will be better understood from the fol lowing description of constructions' embodying our invention, taken' in connection with 'theaocomp'anying drawings illustrative there of, in whichi Figure-1 is a perspeetiveview of o. sectorshaped boit or cnrtonfwithfthe bottom flaps t closed.y Fifi;-l 2 is a, similar View with the flaps open.

Figs. 67 and 'S areviews identical with Figs. 3, 4 and 5 respectively, 'except that 'the tuck-engaging sli-t is 'in a different flap.

Figs'i) and 10 are respectively en end anda perspective View of a. l knock down triangular box or carton ,and Fig. l 1 shows the blank from which the triangular boit' ismade.

In'the construction 'illustrated in'Figs. 1 to` 8 inclusive A designates a secter-shoped pa-` per box oli-carton, which, although herein re paper, stravvho'aid, wood-veneer, orotherthi-n fel-red o as a paperpb'ox, may be made of sheet' material, and which, as, shownv in. this instance, is ciosed at, one end only. The

sides of the box comprise tvv-aequol and simila'r radins sides A A 'anden are-side oom- -posed of two eq lmlmld similar sections A8 A, the radius sides being sually wider'thau the sections forming the are side. In the approved form of box shownthe angle between the radius'sides is vSibont seventy-two degrees or one vfth of a fnll.cirele,so that tive such boxes exactly suffice to form one horizontal layer in the packing pail or receptacle withontwaste of space. It is oiivious,.however, that the boxes might be so proportioned, if


y f .and sections TA? A4; one of said dapsbeing y ilssa layer.

When, asis usually the caser-the pacliing" 5,A pail flares toward the top .it is necessary, in order that the boxes may lit the pail closely, to make them of tapered form but with ythe arc sides only inclined, Athe radius sides being f necessarily perpendicular tothe planes of the top and bottom ends'of the box-'in .order'that the contiguous boxes may come closely in lcontact wthfeach other when'packed within.

the pail. Y yTo this; end' therefore, the radius sides are made of trapezoidal'shape with their top edges longer than their bottom edgesand with their acute angles. toward ,the arcside of f thelboir' (see Figs. 1y and 2),-whilethe-seetiops forming are side 'aretmade of 'thfe'shapebf f truncated isosceles triangles'with `their fto'p edges also longer than( their bottom edges; 'the result being that rthe boxy is larger'at its top or open end than atits bottom orclosed f Y fend, asclearly'shown'in Figs.;1 to' S inclu-v sive. Said'bottoin forclosed end of the boxV Yis formed by'folding together the flaps c. ai',

as a* attached respectively to the sides 'A'. A2

provided with a tuckan'd an'otherwith a slit for engaging said tuck; such engagement serving both to lock the liaps in place and to aidin resisting distortion of the box. "f t Y i -f .To further stiften the box and tosecure a f rmersmoother bottom, one of the remaining flaps (one which is adjaccntto thstuck'ilaps) is' so shaped that when "the: flaps are turned one edge the side to which the tuck yflap-is attached and with its opposite edge will engage thetuck at the place where vthe'l'atter enters the slit, said remaining flap being folded over the outer end of the slit flap and under the tuck flap.' This improved construction and manner of folding the end apswe, regard as cause of the superior rigidity of 'the box th`u`s formed. Such rigidity is`due both' to the more intimate interlocking'of the tuck and slit aps `'with the third flap thanwhen saidtuck and' slit flaps are, as is usually the case, both folded lover said third dap, and to the 'additional engagement secured between the edge'of 'the Athird flap and the tnckat the'place where it enters the slit. Furthermore,the end thus produced is of unusual smoothness owingto 6c the opposite arc side section A", or in the liap 'a' attached to the adjacent. radius side A', the former construction being shown in Figs. 1, 2, 3, ltand 5, and the latterin Figs. 6, 7 and 8. Said lisp a' attached to the rad'ns side A is ofthe bodyof the box and. (except for one small lcorner which, to save stock, is preferdownto form they bottom f it will. engage ywithV bethns-folded.
