, `z claims. (cram- 11) Company, ,St. Paul,

"The ypresent invention relates to the packaging, dispensing ,and feeding of grit, feed, `and the like for live- Jst'ock, particularly for poultry.

.aging means and as a feeding trough.

Such combined containers and feeders'have been heretofore attempted, and although those known to me have been operative, they are of such complicated construction as to be prohibitive from the point of view of cost.

A further objective, therefore is to provide a containerfeeder of simple construction and low cost.

The present invention provides a combined packaging and dispensing carton and feeding trough that can be made or set up complete from a single blank stamped from a sheet of cardboard or other suitable sheet material.

When the said single blank is folded and secured, it forms a carton having four vertical walls and a bottom closure. The bottom closure comprises a rst panel hinged to the bottom of the front wall and eX- tending to the rear wall to form the inside bottom surface of the carton, a second panel hinged to the bottom of the rear wall and extending underneath the rst panel to a position below the front wall, a trough-forming panel hinged to the front edge of the second panel and extending upwardly therefrom in front of the front wall, two end aps hinged to the two ends, respectively, of the trough-forming panel, two vertical slots in the Walls at the front corners of the carton to receive the two end flaps, respectively, stopmembers on the end flaps to engage the walls when the flaps are partially withdrawn from the carton a given distance, and two side closure flaps hinged to the bottom edges of the two side walls,

respectively, each extending across the bottom of the carton underneath the second panel toward the opposite side wall to form the outside bottom surface of the carton. At least one aperture is provided in the front wall opposite the trough-forming panel to permit the contents of the carton to flow into the trough that is formed between the front wall and the trough-forming panel when the end flaps are partially withdrawn from the carton.

An illustrative embodiment is described below and shown in the accompanying drawings, in which:

Figure l shows a closed carton in use as a packaging means for poultry grit or feed;

Figure 2 shows the carton of Figure 1 in readiness for use as a feeder, with the feeding trough open;

Figure 3 is a vertical sectional view of the lower por- Tice 2 tion ofthe carton, showingthe trough in closed position (solid lines) an'd in Iopen position (dotted lines);

Figure :f4 shows `the single blank from which the carton .isformedg and Figures 5, 6, 7 and 8 show successive ystages in the formation of the carton from the blank.

HThe carton has four vertical walls, namely, a front .wail 15, a rear wall 16, .a left sidewall 117 and a right side wall '18. A 'fastening flap 19 hinged to the right edge -of the front wall 15, is glued, stapled or otherwise `fastened to the frontmargin .of the right side wall 18 when the blank of Figure 4 "is folded into the `form shown Yin Figure '5. Conventional fulloverlap V.glue-seal closure iiaps 2l) are provided at the top.

A iirstpanel '25, hinged at `26 to the bottom of the front wall 15, extends tothe rear wall 16.and is secured thereto by a fastening `flap 27, to form the inside bottom surface `of the .carton A second panel 28, hinged at '29.to the bottom of the rear wall 16., extends underneath the first panel 25 to a ,position below the front wall 15. A trough-forming panel 30, "hinged at 31 to the front edge of the second panel 28, extends `upwardly therefrom in front of the front wall 15. Two end ilaps 32, hinged at 33 to the two ends, respectively, of the trough-forming .panel 30, extend into the carton through `two slots '34 and 35, respectively, inthe walls at thefront corners of -the carton, to 'form the end walls of `the trough.

Referring to Figure 3, the top edges 36 of the trough end flaps 32 are arcuate about the hinge 31, the radius of the arc being `of a length to permit clearance of the tops of the slots 34 and 35 by the edges 36 as the trough is opened and closed in use.

The rear portions of the trough end flaps 32 are shaped to extend upwardly above the arcuate top edges 36 to form stop members 37 for engagement with the inside surface of the front wall 15 after the flaps 32 are partially withdrawn from the carton a given distance when the trough is opened.

In making or assembling the carton, the folding of the second bottom panel 28 into its permanent position as a part of the oor or bottom of the carton, and the insertion of the trough end flaps 32 through the slots 34 and 35, are performed as a single operation following the step that is shown in Figure 6. At this point in the assembly process, the side closure flaps 40 are not yet in position, so that the trough end flaps 32 can temporarily extend downwardly between the side edges` of the rst panel 25 and the respective side walls 17 and 18 a sumcient distance to permit the tops of the stop members 37 to clear the tops of the slots 34 and 35 (Figure '7), as'the flap 28 and the attached vtrough members 30 and 32 are being moved into their respective positions in the finished carton.

Thereafter a strip of tape 42 is alixed to hold the trough shut, and the two side closure aps 40 which are hinged at 43 to the bottom edges of the left and right side walls 17 Vand 18, respectively, are then folded into position (Figure 8). The flaps 40 extend across the bottom of the carton underneath the second panel 28 toward the respec tive opposite side walls 17 and 13, to form the outside bottom surface of the carton.

The carton is then filled with the grit, feed, or other flowable material, the top closure flaps 20 are fastened in position, and the carton is ready for shipment and storage (Figure 1).

`When the grit or other material s to be fed, the tape 42 is removed (or slit, as by a suitable tear string) and the trough is opened (Figure 2), whereupon the grit flows into the trough through the one or more `apertures 45` that are provided in the lower portion of the front wall 15, these apertures being in a position to be covered by -the trough-forming panel 30 when the trough is shut.

The panels 30 and 15 lform the front and rear walls 'of the open' trough, respectively, the flaps 32the end thescope of the invention described and/or claimed herein. n
