1 Claim.

This invention relates-to-folding boxes or'cartons of foldable sheet'material such aspaperboard and which are formed from integral-blanks. particularly it aimsto'provide a polygonal device of the class described for use as a dispensing holder or package especially for rolls of waxed or other paper, foil and the like sheets, and'to provide a one-piece blank 'for such'polygonal and particularly hexagonal boxpeculiarily adapted for setting up on machines as known under the trade-mark Brightwood.

In the drawings illustrating by way of example one embodiment of the invention:

Fig. 1 is a perspective View of a dispensing box of'the invention in set-up but open condition;

Figs. 2, 3 and 4 aresectional views on a transverse plane and looking toward the inner face of one end of the set-up box as indicated by the section line on Fig. 1, showing the same in successive stages of closure;

Fig. 5 shows a blank for the'box; and" Fig. 6 is anenlarged detail of an upper corner portion of the closedbox; as at theleftin Fig. .1.

Referring now tothe drawings in more detail and first to Fig. 5, the one-piece paperboard or like blank as there shown is -generally rectangular and comprises a series of integrally united longi tudinal side panels appropriate in number for theformation'of the bodyof'a polygonal box, herein illustrated as hexagonalr- While astoisome aspects of the invention the-boxmayrbeprovided with a greater or lesser numberlof sidesth'an six the constructioniand arrangement as illustrated. is especially adapted:.tormulthpolygonal forms; wherein a loosely. insertedsheetmoll such as-Pt,

Fig. 4, will have. at. the lowerrportiomthereof at least three longitudinal wallshin: approximate" tangential relation-to it.

The several side panelsof .the. box blank will forv convenience. bev identified with referenceto their. position. in theseteup box.. They include. a top. side. or. hinged cover member ll,-.an .upper back. side II. a lower. back. side..l2',.a bottom. side. or.

floor 3, a lower front side It and anupper front side I 5 which herein also. constitutes a hinged cover. member. These longitudinal panels, numbered in the order. from top to bottom in Fig 5,

are demarkedibylongitudinal and herein parallel scored or otherfold lines a, b, c, d, .e, and 7 respectively between each two adjacent panels and upon which'the blankisfoldable'insetting up the box. The scorelinea along the outer edge of the top side ill constitutes a hinge line between the latter and. a longitudinal tuck flap lfi' carried by said top-side and defining one longitudinal" margin 0f'the=b1ank.

The top side or cover panel 10 and the tuck flap I6 thereof havefree edges at the opposite ends. The side panels Il-i5 each have end extensions, to be referred to, the panels proper be r conform to and to close the ends of the tubular box body provided by the side panels lill5 in the set-up state. Asshown said end panels I8 are polygons with as many side edges as there are sides for the box. In the illustrated six sided example they'are hexagonal. In a dispensing roll holder with which the invention is mainly but not exclusively concerned the box sides preferably are of equal width or substantially so. The end panels it accordingly are shown as equilateral hexagons.

The blank is further formed to provide dust flaps is on the end panels I8. These are shown as quadrilateralextension opposite the bottomconnected' sides 9' of the end panels and dc marked from them by score lines 71. These dust flaps is each have a longitudinal edge-with lateral projection l9c substantially in line with the front hinge line e of the bottom panel l3. In the set-up closed box'the dust flaps l 9 are turned in and lie closely parallel to the top cover 19, Fig.

flap [5- thereof. For convenience in closure the sides of the dust flaps opposite the front edges 19a are inclined toward the latter and the outer end edges substantially parallel the hinges h, giving the dust flaps herein a trapezoidal shape.

Referring again to Fig. 5 and the blank thereof, a plurality of the side panels, herein. the lower back panel I2; the upper back panel II and the lower front panel id; have extensions at both ends of the blank there providing glue flaps 20, 2| andZZ; These are so shaped and proportioned that'together they present a total area approach ing that of the corresponding end panel 18.

In setting upthe box the glue flaps at each end are turned into a common transverse plane so as to be received fiatwise againstthe lll!li"'f2l-CE0f' the cor esponding endpanel l8,

' or? which they overlap substantially rnore than halfthe area. In the illustrated example the total glue flap area is approximately of each hexagonal end panel. As seen in Fig. 2 the described glue flaps 28, 2|, 22 overlap substantially the entire upper half of the adjacent end panel i8 and considerably more than one-half of the lower half of the latter, approximately of such lower half in the illustrated instance.

This is accomplished by forming the several glue flaps as sectors and combinations of sectors and half-sectors of the hexagonal end walls l3. In the illustrated example the glue flap on the lower back panel I2 is of substantially equilateral triangular form, equivalent in area to one onesixth sector of the end walls. The adjacent glue flap 2| on the upper back panel H is a trapezoidal quadrilateral of approximately 1 /2 times the area of glue flap 20, that is, equivalent to one and one-half end wall sectors. The glue flap 22 on the lower front panel !4 is of pentagonal form with an area equalling that of the glue flaps 20 and 2| together, equivalent to two and one-half end wall sectors. Accordingly the three glue flaps 29, 2| and 22 will together overlaps the entirety of the corresponding end panel l8 save for the sector immediately adjacent the hinged bottom edge g thereof. At that region adequate strength and rigidity is inherent from the integral relation of the end panels to the blank as a whole.

The described end panels I8 and the several glue flaps 2s, 2 I, 22 occupy the opposite end edges of the bottom panel IS, the lower back and front panels i2 and I4 and the upper back panel H. In the set-up and secured position with the glue flaps adhesively or otherwise secured in face contact at the inner faces of the end panels It said four longitudinal panels H to It are held in relatively fixed non-opening relation.

Among the advantages for the hexagonal sideopening box of the invention is the capacity to 1 be handled in commercial box machines such as those of the Brightwood type. This is largely by reason of the fact that the glue flaps 2|, 2%, 22 at the respective sides of the blank are in line and accordingly may readily have glue applied to them during travel through the machine in the direction perpendicular to the side panels, that is, from top to bottom or the reverse as viewing the blank in Fig. 5. If the face of the blank as seen in Fig. 5 is regarded as the inside it will be understood that the glue is applied upon the underface of the glue flaps 28-42 as the blanks pass through the gluing mechanism of the Brightwood machine.

As previously noted the hinged top panel ill and its tuck flap [8 define one longitudinal margin of the blank and are free of end projections. The opposite longitudinal side of the blank is defined by the upper front side and cover panel Hi. This is hingedly connected at the score line along the adjacent side of the lower front panel M. The respective end edges of this front upper side cover element are each formed with a herein quadrilateral tuck tab 23 hinged along the score or fold line g and projecting longitudinally and angularly. The outer longitudinal edges 23a of these tuck tabs are disposed at such angle to the free longitudinal margin |5a of the openable upper front panel IE on which they are carried that in the set-up and closed condition, as seen in Figs. 3 and l, the tab edge 23a will coincide with the plane of the openable top H].

The tuck tabs 23 of the upper front panel I5 are non-glued, contrasting in this respect to the glue flaps 20, 2|, 22 and are free to contribute to an interlocking relation of the parts in the completely closed position of the box, Fig. 4. Thus the upper front side panel 15 is constituted as an openable folding hinge cover element equally with the cooperating openable top cover element to at the opposite longitudinal side of the blank. It will be understood that the terms such as top, bottom, upper and lower are herein used for identification and without necessary limitation as to the use position oi the dispenser box. The six panels it to It all constitute longitudinal side walls for the box, and the two terminal side walls to and $5 at the opposite longitudinal margins of the blank, adapted to meet along their opposed longitudinal side edges when the box is closed, together constitute openable side wall means having oppositely hinging portions connected to respectively adjacent fixed side walls It and I4. Thus the box is readily openable to receive a roll R which may initially have a diameter greater than the width of any one of the side walls of the box. In Fig. 4 the content roll R shown dotted is assumed as having been partly dispensed and hence of somewhat less-than-capacity diameter.

As seen in Fig. 5, also Figs, 1 and 6, cover locking formations or notches Efix are formed at the opposite ends of the openable top cover panel Ill. extending in from the respective end edges and in line with the scored hinge line a for the tuck flap l5. In the fully closed condition, noting particularly Fig. 6, these locking notches Illa: are adapted to receive the described locking pro ections E90. on the adjacent longitudinal edges of the flaps [9, thus affording a positive interlock for retaining both hinged cover portions H! and i5 closed.

Assuming the blank to have been glued, folded and set up to the completed form of Figs. 1 to 4, with the four side walls I I to I4 secured adhesively or otherwise by flatwise attachment of the glue flaps 20-22 against the adjacent end panels l8, the content roll R of wax paper or other sheet in roll form is inserted, the box being open as in Figs. 1 and 2. The free tuck tabs 23 are turned in and the openable front side cover 15 is swung inwardly to the position as in Fig. 3. The dust flaps l9 carried by the secured end panels [8 are bent in over the adjacent ends of the roll. The other or top openable cover I0 is closed down with its tuck flap 15 inserted inside the free longitudinal edge of the front cover member I5; Fig. 4. As the cover members are brought to full closed position the locking notches I02: come opposite the adjacent longitudinal edges ISa of the dust flaps I9 allowing the latter to spring laterally or forwardly out into the locking notches, positively locking the parts in closed position. The tuck tabs 23 cooperate in this closin and locking function, limiting down movement of the top cover it and aiding in providing rigidity and a tight closure for the several interrelated hinged closure elements.

The described construction further facilitates the dispensing of the contained supply roll R as will be apparent by reference to Fig. 4. There the leading edge of the overwound roll R is indicated as turned upwardly around the free edge of the tuck flap I8 and extending outwardly in the crevice between the two closed and locked front and top cover panels I0 and IS. The free edge of the front panel l5 may be constructed or treated to serve as a cutting edge, serrated or otherwise, as y p egnation with stiffening material or by attachment of a metal or other cutting edge. To facilitate access to the leading edge of the sheet or strip material of the roll without opening of the box the top cover Hi and tuck flap it may be formed with one or more cut-scored areas or aperture-forming portions Illa, l6a, Figs. 1 and 5, for access by the thumb and forefinger of the user.

My invention is not limited to the particular embodiment thereof illustrated and described herein, and I set forth its scope in my following claim.

I claim:

In a folded paperboard box for use in a dispensing package for sheet rolls, an elongate tubular hexagonal body for use in horizontal position, comprising an elongate rectangular horizontal bottom wall, lower front and lower back side walls continuously along and integral with the respective horizontal longitudinal edges of the bottom Wall, an upper back side wall coextensively along and integral with the lower back side wall, glue flap extensions hinged at the opposite ends of each of said lower front, lower back and upper back side Walls and infolded at right angles thereto, the bottom wall having extensions at each end by an amount equal to the thickness of said side wall glue flap extensions and having integrally formed across each of said end extensions an hexagonal vertical end wall turned flatwise against and adhesively secured to said side wall glue flap extensions in fixed relation thereto permanently closing the ends of said tubular hexagonal body, said hexagonal vertical end walls having at the transverse edges opposite the respective bottom wall extensions infolded quadrilateral dust flaps each with a longitudinal edge portion having a lateral projection positioned to intersect the vertical plane containing the bottom wall front longitudinal edge, a pair of hinged openable non-sealed adhesivefree elongate rectangular top and upper front side closure Walls coextensive with the mentioned side walls and hinged along opposite longitudinal edges to the upper longitudinal edges respectively of the upper back side wall and the lower front side wall and hingingly closeable toward each other into longitudinal juncture respectively in horizontal and in inclined planes completing the closure of said tubular hexagonal body, said hinged top closure wall carrying an adhesivefree longitudinal tuck flap, said hinged upper front side wall having at each end a transverse tuck tab receivable in closed position along the inner face of the adjacent end wall and with the upper longitudinal edge of each said tuck tab abuttively underlying the closed hinged top wall, and longitudinal locking recesses at the ends of the top wall longitudinal tuck flap engageable respectively with the aforementioned projections of the longitudinal edge portion of the dust flap of the adjacent hexagonal end wall thereby to retain both the hinged closure walls in closed position.
