E P M O H W R DI SPLAY CARTON Filed July 27, 1954 FIE-E FIE-'3 v INVENTOR. #05527 M Home:

Patented Dec. 3, 1935 UNITED STATES ATENT OFFICE 1 Claim.

My invention pertains to a display carton adapted to serve the alternative function of a closed box, the whole being constructed from a single sheet of material appropriately scored, creased and folded while addition-ally formed with a slit through which a tongue is adapted to be inserted as an interlock and also provided with a struck-out tab.

I am well aware that the patented art of folding paper boxes, from stock having slits and creases, is highly developed, but believe my origination of established commercial favor to comprise patentable features, being of truncated, partially-pyramidal form adapted, when its cover 15 fiap is held in a raised position, to display contents through an oblique open side.

My familiarity with prior patents includes the following: Smith No. 944,46l-Burzynski No. 1,370,279Chaney No. 1,563,687Lasher No. 1,717,456, and Larkin No. 1,881,707.

economical shipping box adapted to have one side flap held in a displaced position while folded upon itself to display surmounted advertising thereby revealing a plurality of stacked commodities arranged as tier-rows with progressively fewer in each superimposed row; together with a front, low panel adapted to cooperate with the back and two sides to prevent disarrangement of the s stacked contents which, if of cylindrical form, would otherwise occur owing to gravitational thrust. Other minor features will have their merits better understood during reading of the specification which follows explanation of the 25 figures of the drawing in which:-

' Figure l is a plan view of the blank used for the construction of a display carton embodying my invention.

Figure 2 is a somewhat enlarged plan view 49 with back and two sides raised to a vertical position.

Figure 3 is a sectional view from front to rear showing the carton fully assembled and filled with confection packages (merely exemplified by A disclosure of twenty cylinder shaped packages) and further showing a rear end wall exercising the function of a cover flap to convert the display carton into a closed box.

Figure 4 is a perspective view of my display carton showing the cover flap raised, folded upon itself and held in an upright display position by engagement of its free end edge behind a projecting tongue.

My carton may be formed from a single piece 55 of cardboard stock shown in Figure 1 to com- The objects of my invention are to provide an prise a bottom i two side walls 2 and 3 each of which has converging front and rear edges connected by edges 2a and 3a which will constitute the top edges when the hinged side walls are swung to a vertical position as facilitated by 5 their creased-line connections with opposite sides of the bottom l. A rear end wall designated in its entirety by the numeral l includes a section 5 of the same width as, and in creased connection at 30: with, the bottom i. The side edges of the section 5 have the same length as the side edges of the side walls 2 and 3 to which they are to conform when the section 5 is elevated to constitute the back of the carton or box. Adjacent to the back section 5, the rear end wall t includes a smaller section 6 of the same width as the length of the edges 2a and 3a. Along the creased line connection which the section 5 has at l with the section 5 there is provided a struck-out tab 8 the function of which will hereinafter appear. The remainder of the rear end wall i, designated in its entirety by the numeral 9, is of somewhat greater width than its line of connection it with the section 6 and comprises two sections it and I2 which are separated by a creased line Hi. The section 5 l is wider than the section I? and is partially bounded by the free end edge 14. Both sections I l and ii are transversely creased in line with the lateral edges of the section 6 to provide flaps Ma and Wu.

A shorter front end flap I?) attached to the bottom 5 along iiict comprises two sections it and ii of equal width as determined by the middle creased line it. The bottom of the section it may carry advertising matter because it is ultimately to be exposed to view as shown in Figure 4. Likewise, the bottom of the section l i is to be supplied with some advertising message because ultimately to appear to view as shown in Figure 4 when the contents of the carton are to be displayed during 0 retail sales therefrom.

The forward oblique edges of the side walls 2 and 3, commencing at their points of. junction with the bottom l, are provided each with an ear or small flap which are numbered iii and 2% respec- 45 tivelyand which have creased line connections indicated by the broken lines Wu and 28a. The rear edges of the side flaps 2 and 3 have creased line connection, the former with a full length and otherwise larger flap 2! supplied with an oblique 50 slit 22, and the latter with a flap 23 fashioned at one end with a tongue adapted for insertion through the slit 22 preparatory to overlapping the flaps 2i and 23 outside of the raised back or rear Wall section 5, whereby to reinforce and es- 55 tablish an interlocking connection designed to hold the side walls 2 and 3 in vertical parallelism. The tongue 25 is insertable through the slit 22 from either side of the flap 2!, but in Figure 4 is shown to have been inserted through the rearward side of the flap 2! whereby the tongue 22 also contacts with the back 5 when the carton is assembled, as shown by the broken lines in Fig. 4.

The cylindrical confection packages, shown packed in my carton in Figure 3, are designated by the numeral 25 and are twenty in number with six in the bottom row, one less in each superimposed. row and two in the upper row.

In assembling the side walls 2 and 3 are first swung up and then the flaps 2! and 23 interlocked outside of the back section 5. Next, the ears I9 and 2e are bent to extend towards each other and the front end wall folded therearound until the crosswise extremity of the section I"! bears against the bottom l thus besides forming a front stiffening connection between the side walls 2 and 3 also providing a forward retaining Wall to prevent dislodgment of the stacked contents. During shipment as a closed box the short marginal flaps i la Gila are bent at right angles to their sections l i and i2 and caused to engage the inner front margins of the end walls 2 and 3 whereby the section ii forms the small top of the box and the sections I l and I2 together form the front cover flap, the extremity l4 being inserted behind the folded section I! and brought into engagement with the bottom as appears in Figure 3. When the contents are to be displayed the cover flap is withdrawn and folded along the creased line l3 to double it upon itself preparatory to securing a middle portion of the edge 14 behind the projecting tab 8 whereby the folded cover flap is maintained in its elevated position as shown in Figure 4.

I claim:

A carton formed of a single piece of material creased to define a bottom, a rear wall, side walls of substantially triangular formation having upwardly converging front and rear edges and a front fiap creased from side to side intermediate its ends and adapted by itself to be folded in a position at an angle to said bottom with the ends thereof in the plane of the forward inclined edges of the side walls, each of said side walls being provided with an ear projecting from only a portion of its front converging edge and adjacent to said bottom, said ears adapted to extend toward each other when the side walls are raised and further adapted to be confined between the folds of said folded front flap, each of said side walls being provided with a flap projecting from its rear converging edge and adapted in overlapped arrangement to cover said rear wall, said. side wall flaps to each other being fashioned one with a slit and the other with a tongue adapted for insertion through said slit, said rear wall having attached to'its upper edge a cover flap adapted to conform to the tops and front converging edges of said side walls, said cover flap being provided with an inwardly struck-out tongue on a fold line thereof at the top of the side walls and adapted to engage and hold the bottom edge of said cover flap when raised and folded upon itself whereby to display the step-like arrangement of piled contents of the carton during retailed sale thereof.
