Throughout theseveral views of drawings similar reference characters are employed to denote theV same or similar parts.

As is noted above, this invention pertains to a carton which may be employedrfor a `display carton; as well as a vshipping,containeiaancl wherein the contour of the deviceenclosed therein cooperates with ,the structural elements of the carton.

Specifically, and referring to the drawings, la blank is cut or died from.cardboard or like material"to-'the form substantially illustrated in Fig.V

1, and which, in the set-up box, provides a rectangular panel I5 constituting the back of the carton.

The panel l5 is Adeined along its longitudinal edges by fold or crease lines `I6 and I1, and along its transverse edges by fold or crease lines I8 and I9.'l The said creasek Vor V-fold Jlines respectively,

hingedly connect flaps to the back panel, which, in the erected carton, form the walls thereof.

The naps connected by hinge oiold lines I6 and l1 are substantially identical, and it -is deemed suilicientif but one of them be described in detail. Accordingly, hinge or fold line ll connects with the back panel I5 nap 20 longitudinally divided by hinge oriold lines 2I, 22, 23 and l2li, thereby providing outer Ywall panel 25 between crease or fold lines I1 and 2l.

vFold or crease lines` 2| and 22 define the upper portion wall-panel 26 whilei -fold or crease linesV 22 and 23 define an internal shoulder panel-2'l. Fold -or crease lines 23 and 24 denne between them the inner wall lower portion panel'28 with the fold or crease line 24 and outer edge of the ilap 20 dening a glue flap 29 which, while being processed, has applied to'it on the surface ex-v posed in Fig. 1, glue or other attaching mediumv The ends of the outer wall panel 25 are deiined by fold or crease lines v3l and 32, while the re-` mainder of the panels of the flap 20 have their ends definedv by outlines.

The opposite` corner of the inner wall top portion panel'adjacent the fold or vcrease line 2l is 3 cut by right angle cuts 33 to provide ears 34 and 35 at the said opposite ends of the panel 2B, and which ears are hingedly connected to the outer wall panel 25 by the fold or crease line 2l. The lower end, in the-erected carton, the shoulder panel 21, is cut back as at 36, thereby providing a stepped back edge 31. The inner Wall lower portion panel 23 adjacent the stepped back 31 of shoulderpanel 21 is likewise inwardly out as at 33,.havingra cut back 39 behind the cut back 31of the shoulder21, and=which, inthe erected carton is higher than the stepped back 31. The shoulder panel 21 near its other end is pro- 4 trated in the upper portion of Fig. 1. In other words, the blank upon leaving the machine has both flaps 25 in the position of that illustrated at 2B in Fig. 1.

The user then sets Vup the carton as illustrated at cne end in Fig. 2, which is accomplished by merely raising the wall panels from their flat position to the up-standing position illustrated in Fig. 2, which automatically places the l* inner'wall portion panelf2$g adjacent the outer tion 28 parallel with the outer wall 25, but invided with an elongated aperture inwardly spaced from its cut end a distance substantially equal to the inward spacing ofthe outback 31 from `its cut end. The inner wall lower portion panel 28 adjacent the fold Yor crease `line 24 lisy provided with elongated apertures 4I and 42, eachy spaced from its cut line a distance substantially I` 9 and I4 denne between them outerwall panel 41,

while fold Vor cre'ase'lines 44 and 45 d-enelbetween them 'top wall panel 48.. vFold or crease lines 45 and 45 define Vb'etxflfeer them inner wall panel 49 with the fold or crease'line 45 and outer g end of flap 43 providing a tucking flap 5D. Transverselyv theouter Wall panel 41 is defined by fold or crease lines 5I and 52, while the top, panel 48 is defined transversely by'cu't lines.

fold orcrease lines 53and54 and partly by fold or crease lines 55 and 56, of Which fold` or crease lines and 55 are inwardly spaced a greater distance than the fold or crease lines 53 and 54. The inward spacing of said fold or crease linesbeing substantially equal to the width ofthe shoulder panels 21 otapshz. The fold or crease lines 53 4and'5lll respectively,hingedlyfconnect to the inner wall panel 49 tucking aps 51 and 58, While the fold or crease lines 5 5 and 55 of said inner wall panel 49 likewise hingedly connect thereto tucking fiaps 59 land 69. The inner wall panel 49 between the inwardlyysteppedhfold or crease lines. thereof is provided wthtabsl and 62 separated from the tucking iiaps. 59 and 65 by the cut `lines thereof. I

At the same time the vrcorner' pieces 65' are arranged vertically to the back panel I5 with the ears 35 likewise upwardlyv projecting. Y

l 'lhegiaps 1D and ears 35 are then folded on their vrespective hinge lines to lie parallel with the back panel I5. The end wall naps-43 are then upwardly bent on fold or hinge line I5, which automatically foldsY the corner pieces 65 on them-fselves about the diagonal score or liold lines 66',

and at the Sametime causes the portions 61 and. 68 to be transverselydisposed across the end oi" the carton with th'e'tucking flaps 10 above the` ears 35.

ing flaps 51, 58,', 59 and 6I) are folded normalV to the inner wall panelA 49, while the end spacing' flap 5 is likewise folded to be normal to thev outer wall 49. The Vtop* wall portion 43 'is then folded to be parallel vwith the back panel, and

which fold takes place about the fold o'r score' line 44, whereupon the'inner wall panel is folded on the score or fold line 45 to lie parallel with the'y outer wall 41, Vand be normal tothe back I5 .The said inner wall 49 is locked in this position by causing the tongue'sSI and 62 to engage behind the shoulder or cut back 31 of the internalshoulder panel 21 at one side or one end of the carton, "while the s'aid tonguesfBI"andIZA at the yother end of the carton are adapted to" snap into the It will bel notedfrom Fig. 3, that the top wall, panels '48 provide surfaces admirably adapted for' printing for advertising purposes or explanatory information with respect to the article packed therein. A y

It "will be further noted from Figs. 3, 4, and 5 that the vcarton can readily and advantageously display the article therein.

ACut back 38 in the panel portion 28 Ycooper-` atingwiththe'cutback 36 in shoulder panel 21 in the erected box provides a Ynotch 1I immediately above the*end-wall?construction, and

which is the bottom of the carton when used as' a display. This notch 1I is utilizedto receive.

theradio ange. 12, illustrated in phantom lines in the drawings, of the articlegpacked therein. The body' portion 13,;likewise illustrated in phantom lines in the drawingsy closely engages the inner wall lowerrpanels28 to thereby snugly fit the article and prevent lateralumovement thereefwithinfthe carton. AThe ropas shcwn in phantom lines in the drawings, closely engages wth the inner end Wall panel,v and which The router wall panel :41 'is thereby placed in its nal position whereupon the tuck' end *wallonstruction forms thetop of ,thedisplayxcarton..

A, Aslgillustrated-in Figs. 6, 7 and 8, the, various tucking fiapse, 51;.5B 59and-60 extend between the inner and louter bottom and top panels 47 and 49,A andact-asbraces to prevent the collapse of f said inner and outer panels toward one another. In addition, the tucking flaps '10. of the corner pieces actas braces asdo the. ears 35., By the construction just described, considerable pressure can be applied either from the .outside-of the carton in an` axial. di-

rection with respect to :the article therein, or

the article ,packed can exertv a considerable outward pressure and be retained againstinjury within the carton, both while on display andin shipment. u o

In .other words,.by this invention there has been provided a shipping and.y display carton adapted to conform withr the 'several contours andl dimensions of the article to be shipped therein and securely hold said article against relative or independent movement while in shipment, and at the same time hold the article regardless of its weight when on display.

Thev construction .of vthe carton conveniently enables the use of an advertising nap attach able kto theA carton by the shipper. As. illustrated in-Figs. .3 and .9, the advertising panel 'i6 is of a length .substantially equal to the lengthvof the carton,land a width that is substantially equal to the widthof the carton. Secured vto the advertising panel 16 by means of hinge, tabs 11. and 18 is a flap 19, which has projecting beyond the tabs 11 and 78 ears 'Z9 and y8G..

Afterthe carton has been erected, the ears 'Hiand BQ .are inserted between the bottom and topinner portion ioldable tabs 5i) and the adjacent portion of the inner vertical .wall panel 2'5 .whereby .the-,hinge tabs are inwardly lof said top and.4 bottom, vbut substantially adjacent thereto. By. this construction the advertising panel may be; opened to stand parallel with the carton, or atanyangle iorwardlyvor rear.- w'ardly .thereof as desired,.and as illustrated in Fig.., 5. in solid. and: dottedlines. yIn order to hold theadvertising panel .in ang/position of adj'usftinent,...its outerlower .corner is., provided with/'a drag tabfSi which. frictionally engages the surface, as a counter or shelf, on which the article in its cartonis being displayed.

By. a.- substantially similar construction a shorter tab, such as -a pricetag 82, may beattached to the other side of the carton.

The shipper would fold the tab or tag 82 onto the front. of the carton, and would accordingly fold the display panel lonto thefront of the carton and apply a lidto, or other slip cover,

overv the carton,v;whereupon itand its article.`

is.- ready. for shipment .tothe .seller ,or user.

The modication illustrated in Figs. 11 to 14 provides additional strength or vsupport to` the.

top.; and bottom to .resist additional pressure axially-of thearticle. The modication of the blank .consists .in yhingedly connecting. to. each tucking iiap 1li',V (in Fig.. 1 tucl ing-fiap-iil byV a hinge or fold line 33, a horizontal streng h` ening hap i.
