STRUBLE BY W w M 43 ATTORNEYS New This application relates to boxes, particul-arly'to handle constructions for boxes formed from a unitary sheet of material and including .a folding lid.

The primary object of this invention is :to provide a handle construction for garment boxes and the like which folds 'flat upon the box blankfor storage and which is easily extended to provide a carrying handle .on :the

assembled TbOX. t

Another object of the invention is to provideam-improved handle construction for paperboard boxes and .the like which is inexpensive and easy to manufacture and wherein a backing and reinforcing strip'for one of the t boxlpanels has an integral flexible handle portion with r by mesne United States Patent panel 13 having inwardly extending flaps 1.4 fixed to the side panels 11 and '12, respectively, with .the flaps 14 and the side panels having diagonal fold lines '15 providing for folding of the side and front panels onto the :bottom 10 to collapse the assembled box for storage in the usual manner. At the .edge of bottom 10 opposite from the panel 13 a rear wall panel 18 (Fig. 2) extends upwardly, being connected to bottom panel 10 along a fold line =19.

The lid of the box is arranged to fold over thebot- ,tom of main body section in telescoping relation therewith,-and the lid 'thus includes a top panel 20 connected along a fold-line 21 to rearwall panel 18, and lid

side wall panels

22 and 23 extend from top panel 20 to .embrace the

side panels

11 and 12 when the lid is .closed. The lid front panel '24 .extends from the front edge of top panel '20 .and includes flaps secured to side panels 22 and-23, respectively, with diagonal fold lines 261extending across flaps 25 and the ends'of the side panels to provide for folding of

panels

22, 23 and 24 flat upon the top panel 20.

Side panels

11 and 22, 12 and 23, are integrally con- .nected by flaps '30 having V-shaped notches 32 therein,

an extensible folding connection at one end .thereoftto t :the remainder of. the strip which provides for extension of the handle portion throughan aperture-in the box panel and for =flat foldingof the handle portion for storage and shipping purposes.

Referringto the drawings, which illustratej preferred embodiments of the present invention, a typical "folding "box construction of the type used to carry garments ,and the like is shown -'er n bodying the handle 'co nstruction of the-present invention. The box includes a bottom or main -bodysectionjihaving a -bottom panel 10 and side .panels 1311 and e12=extending=upwardly therefrom. At the ttrcnt not the :box as wiewedxin Fig- "1 there is a ifront and .diagonal fold lines 33 extending from the apex of notches '32 to the. corners of the

panels

10 and 20, .re- .spectively, provide for bellows folding of the flaps 30 as :the lid is closed, and as shown in Fig. 1. The bottom front panel 13 is slit to provide tongues 35, the :opposite sides'of which are receivable within slots '36 in top front panel :24 to lock the lid in .closed position. Also, a suitable notch 37 may be cut in the free edge of front panel 2.4 to facilitate grasping of the .lid for opening thereof. 7 i

Referring to Fig. 2, panel 18 has a central :longitu- .dinally extending =slit .40 therein, and also transverse tgenerally V-shaped slits 42 .extending from opposite ends of slit .40 andhaving short longitudinally extending .por- .tions143 at .opposite'ends thereof. 'Foldxlines extend between adjacent .ends .of these slits to define longitudinally extending flaps 45 and short transverselyextending flaps 46 which are bendable to an open position wherein they define a substantially rectangular aperture in :panel 18, as shown in Fig. .4. A backing and reinforcing strip 50 is adhered to the surface of panel 18 interiorly of the box, with adhesive preferably applied to the stippled areas shown in Fig. 2. Corresponding areas of the strip which adhere to the adhesive .coated parts of panel 18 are cross-hatched inFig. 3.

Thus, one .end 52 of strip 50 is fixed to panel 118, and

the .other end '53 is free from attachment to :thebox.

spacing between the slits 54 being no greater than :the

width of the aperture in panel ;18,.as .defined by the space between the longitudinally extending fold lines .44 therein. A fold line 55 extends transversely of the strip between adjacent ends of slits 54 at the fixed .end 52, and at the other end .of .slits 54-there is a fold line 56 which extends transversely of the entire free end 53 of the strip. The outward .portions 58 of strip 50 between slits 54 and the sides of the strip are preferably adhered over asubstantial part :oftheir length :to panel :18, and fold lines 60 extend across outward portions 58 at a point spaced fromfold line 56 to .provideextendable foldingconnections between the free -end of the handle portion 62 and the remainderof the strip. The

spacing between fold lines 56 andc60p'referablyis such that the length of 'the' outward portions 63 (between these lines .is equal to about one-half the.distanceibetweenthe adjacent -transverse fold eline 44 "in panel -18iand tfold :.line 56 with the strip 1 in Tits .flat folded or retracted 'aPDSitiQH- "53f. 3 Referring to Figs. 4-8, the carrying handle is extended simply by pressing the handle portion 62 against the

flaps

45 and 46, causing these flaps to bend outwardly as shown in Fig. "7. ;As handle portion 62 is flexe'd;.the free end 53 of the strip consequently is'drawn toward the central'aperture in panel 18 by the folding over of the extensible Connection between it and the freeend of handle portion 62. The outward strip 'portions 63 are 1 thus folded between the free end 53 and the adjacent outward portions 58, asshown in Fig. 8, 'and the'carrying handle is locked in its extended or carrying position as shown in Figs. 5 and 8 with thefree .end of handle portion 62 below the adjacent end of' theaperture. When the handle is fully extended flaps .45fmay .fold inwardly to their original position, substantiallyclosingthe-aperture in panel 18, and flaps 46 extendalong the ends 'of handle portion 62.

' A modified handle construction accordance with the invention is illustrated in Figs; 912. Fig. 9 shows the same box construction as in Fig. 2, and accordingly like a reference numerals have been applied to the parts, since slits 72 may be curved as shown at 76 toprovide for additional flexibility in .the extendable folding connections between the ends of handle portions 75 and the outward ends of strip 70, which are not attached to the box.

These 'exte'ndable connections. are provided by fold lines 78 extending across the strip at opposite ends of the handle portion and generally tangent to the curved ends 76 of slits 72. Spaced inwardly of these'fold lines 78 are additional transverse fold lines 79 which extend across the outward portions 80 of the strip between slits 72 and the'sides' thereof, and which define outwardly folding portions 82 in the strip between the

fold lines

78 and 79. The outward portions 80 are cross-hatched in Fig. 10 to indicate the sections thereof which adhere to the adhesive coated parts of panel 18 in Fig. 9, indicated by the stippling thereon. The dimensions of the parts, particularly the outward folding parts 82 are.

such that when handle portion 75 is pushed against the

flaps

45 and 46, as shown in Fig. 11, the extendable folding connections provide for movement of the fold lines 78 to a position substantially directly beneath the transversely extending fold lines 44 of flaps 46. The.

of said strip between .said slits and the sides thereof being secured to the interior surface of said wall panel on opposite sides of said aperture, at least one end of said strip being free from attachment to said box, and an integral folding connection between said free end of said strip and the adjacent end of said handle portion providing for retraction ofsaid handle portion to a flat folded position within the box and for extension of said handle portion through the aperture to a carrying position outwardly of the box.

2. In a box having a top and bottom integrally connected through an end 'wall panel thereof, said end wall panel having a central slit extending-longitudinally there of and a plurality of I slits extending laterally of said central slit, the adjacent ends of said slits being joined by fold lines defining therewith flaps movable to provide an aperture in said panel located substantially centrally thereofpa backing strip'for said Well panel having longitudinally extending slits therein defining a flexible handle portion therebetween'of a width no greater than the width of said aperture, the outward portions of said strip between said slits and the sides thereof being secured to the'interior surface of said wall panel on opposite sides of said aperture, at least one end of said strip being free from attachment to said box, and an integral folding connection between said'free end of said strip and the adjacent'end of said handle portion providing for retraction of said handle portion to a fiat folded position within the box and for extension of said handle portion through the aperture to a carrying position outwardly of the box.

3. In a box having a wall panel with an aperture therein of substantially greater length than width, the combination of a backing strip secured at one end to an interior surface of said panel and extending across said aperture, the other end of said strip being free from attachment to said box, said strip having a pair of slits extending lengthwise therein spaced apart no greater distance than the width of said aperture, said slits terminatingfat one end adjacent the edge of said aperture at said secured one'end of said strip, the length of said slits being greater than the length of said aperture to define relative position of the parts in the extended position i of handle portion 75 are shown in'Fig. 12,1wherein the flaps 45 are folded inwardly to substantiallyclose the aperture in panel 18.

The present invention thus provides a handle construction which is relatively simple and inexpensive to manufacture, which is easily extended to its carrying position, which is firmly secured to the box, and which is readily adaptable to use with a wide variety of types and sizes of boxes.
