SUMMARY OF THE INVENTION The carton of the present invention has a bottom panel to which end wall and side wall panels'are foldably attached. To provide the exterior ledges, ledge panels are foldably attached to the top edge of the end wall panels. These ledge panels are generally of a smaller height dimension than the end wall panels and overlie the outer face of the end wall panel to form an exterior ledge at the top of each end of the carton. The thickness and strength of the ledge can be increased by placing additional panels between the ledge panels and the wall panels. To provide corner strength two sets of corner connector panels are used, one set foldably attached to the side edges of the end wall panels and the other foldably attached to the side edges of the ledge panels. These corner connector panels overlie the inner face of the side wall panels with the first corner connector panels located interiorly of the second corner connector panels. The structural integrity of the carton is maintained by locking panels foldably attached to the upper edge of the side wall panels which overlie the inner face of the side wall panels and sandwich the first and second corner connector panels between them.
The invention is described more specifically below in conjunction with preferred embodiments and the accompanying-drawings illustrating these embodiments.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 depicts a pre-scored'single piece blank 10 from which a preferred embodiment of the carton can be prepared. The blank comprises a rectangular bottom panel 11 containing a plurality of spaced apertures or slots 12 along its side edges. A pair of generally rectangular side wall panels 13 are foldably attached to opposite edges of panel 12 by score lines 14. Similarly, a pair of generally rectangular but slightly tapered end wall panels 15 are foldably attached to opposite edges of panel 12 by score lines 16. The purpose of the taper is to provide a carton whose walls slope slightly inwardly instead of being completely erect.
The exterior ledges of the carton are formed from the three panels l7, 18, 19 which are foldably interconnected in series, with end panel 19 of the series being foldably attached to the top edge of end wall panel 15. When the blank is assembled, panel 19 becomes an outer ledge panel while panels 17, 18 become inner ledge panels. Panels 17, 18am primarily intended to add thickness and strength to the ledges. Panel 19 is foldably attached to panel 15 by an intermediate thin shoulder panel 20 and the score lines 21 at opposite edges of shoulder panel 20. In the same fashion, inner ledge panel 18 is foldably attached to outer ledge panel 19 by a thin shoulder panel 22 and the score lines 23 at opposite edges of shoulderpanel 22. The other inner ledge panel 17, for reasons which become apparent when the assembly of the blank is described, is foldably attached to adjoining panel 18 by a slit score line 24.
The end structure of the carton is connected to the side structure by a first set of corner connector panels 25 which are foldably attached to the side edges of the end wall panels 15 along score lines 26, and by a second set of corner connector panels 27 which are foldably attached to the side edges of the outer ledge panel 19 along score lines 28. Panels 27 have a small cut-out 29 so part of panel 27 does not extend below the ledges in the assembled blank. Panels 27 also contain a tab 30 which upon assembly of the blank fits into the slots 12 of bottom panel 11 to assist in holding panels 27 in place.
To maintain the structural integrity of the carton, there are locking panels 31 foldably attached to the upper edges of side wall panels 13. Panels 31 have at their bottom edge tabs 32 which upon assembly of the blank fit into the slots 12 of panel 11 to assist in holding panels 30 in place. Panels 31 are foldably attached to panels 13 by a thin intermediate shoulder panel 33 and the score lines 34 at opposite edges of panel 33. In cases where the fold mechanism between adjoining panels includes a thin intermediate shoulder panel between the adjoining panels, it will be seen that additional panels are intended to be located between the two foldable panels. The intermediate shoulder panel provides the space required to accommodate these additional panels while at the same time facilitating the foldability of the two adjoining panels. While shoulder panels are preferred under such circumstances, it is to be understood that they are in no way essential. It will also become apparent that in the assembled carton, the shoulder panels provide flat, smooth surfaces which are aesthetically pleasing and functionally desirable.
The sequential assembly of the blank is shown in FIGS. 25. Referring to FlGl. 2, the end wall panels are elevated along fold lines 16 into an erectedposition. The outer ledge panel 19 are then folded downwardly toward the outer face of end panel 15 but not flush against panel -15.'lnner ledge panels 17 are then folded inwardly against inner ledge panels 18 along the slit score line 24 until panels 17 are in face to face relation with panels 18 as shown in FIG. 2. For this reason, a slit score line is required between panels 17 and 18. Panels 18 are then folded upwardly against the outer ledge panels 15 to sandwich panel 17 between them and panels 19, as shown in FIGS. 3 and 6A. In effect, the inner ledge panels 17, 18 have been sequentially In the completed carton shown in FIG. 5, the corner connector panels 25,. 27'are sandwiched between the side wall and locking panels as best shown in FIG. 7. This arrangement maintains the structural integrity of the carton by holding the end wall panels in an erect position. End wall panels 13 cannot collapse outwardly because the top edges of corner connector panels 25,
- FIGS. 6B-6C, respectively. Of course, additional inner folded one on top of the other to produce a stack in which, the panels 17, 18 rest ontop of each othersThis stack is then located between the outer ledge panels 19 and the end wall panels 15 to add thickness and strength to the ledges (see FIGS. 3 and 6A). Although only the two inner edge panels17, 18 are shown in the drawings, a plurality of such panels could be used in place of panels 17, 18, with the panels foldably attached to each other in series. An end panel of the series could then be foldably attached to the outer ledge panel 19 in a manner similar to that by which panels 18 are shown to be attached to panel 19. In such a case,
these panels would be sequentially folded one on top of the other to produce a stack of the panels which would ,be located between the outer ledge panel 19 and the end wall panels. Similarly, in certain cases, panel 17, or both panels 17 and 18, could be omitted having the respective ledge panels only panels 18 and 19, or 19 alone (see FIGS. (SB-6C). I
Once inner ledge panels 17 and 18 are folded into place between outer ledge panel 19 and'the end wall panels 15, the corner connector panels 25 and 27 are folded inwardly toward the bottom panel 1 1 along score lines 26,28, respectively, until they come into approximate alignment with the scored side edges 14. of bottom panel 11, as shown in FIGS. 3, 4 and 7. Panels 25 and 27 are in face to face relation, with panel 25 located interiorly of panel 27. The tabs 30 on the bottom edge of panels 27 are then inserted into the slots 12 in the bottom panel 11 to hold the corner connector panels in place. The inclusion of tabs 30 on panels 27 is an optional feature and an acceptable carton can be prepared without tabs 30. v
The side wall panels 13 are then folded upwardly along score lines 14 as shown in FIGS. 3-4 until panels 13 are in face to facerelation with the outer face of corner connector panels 27. The locking panels 31 are then folded inwardly until they overlie the inner face of sidewall panels 13 and the corner connector panels 25, 27 as shown in FIGS. 4, 5 and7. The tabs 32 at the bot tom edge of the locking panels are then inserted into the slots 12 in bottom panel 11 to frictionally hold the locking panels 31 in place. Any suitable means for holding the locking panels in place other than tabs 32' and apertures 12 could be used. For example, panels 31 could be stapled, glued or otherwise attached to side wall panels 13 and/or, corner connector panels 25, 27.
ledge panels could also be used. In such case,thc additional panels could be foldably attached to theedge of panels 17 opposite that which attaches panels 17 to panels 18. It would also be possible to use as the inner ledge panels, panels which were not necessarily attached to the blankat all. For example, a separate detached panel or a separate detached stack of panels could be inserted between outer ledge panels 19 and the end wall panels, andif necessary, glued or otherwise attached to the carton structure to. thicken and,
strengthen the carton ledges.
In the assembled carton of FIG. 5, it is seen that the shoulder panels 20 and 33 cooperate to form a broadened, smooth, flat peripheral rim around the top of the carton. This rim imparts an attractive, finished appearance to the carton. The shoulder panel 22 on the other hand provide a smooth underside for the ledge structure as best shown in FIGS. 6A and 6B, which facili' tates manual handling of the carton; especially a loaded carton, since the carton will ordinarily be grasped by the ledge with the fingers in contact with the underside of the ledge.
The dimensions and shape of the carton, the blank and the various panels of the carton can vary considerably without departing from the scope of the invention. For example, although the embodiment shown in the drawings has walls with a slight inward taper, the walls could just as well be made upright without a taper by modifying in known manner those score lines of the blank which are responsible for the tapering.
The carton can be fabricated from any suitable mate rial. Corrugated paperboard is a preferred material be cause it is relatively inexpensive and readily available. Different thickness of the corrugated paperboard can be used and if a thicker variety of paperboard, such as double-wall paperboard, is used, the ledge structure may require only a single ledge panel, such the outer ledge panel 19, for the required thickness and strength.
Single-wall paperboard, as'shown in the, drawings, is a preferred material for the carton and when single-wall paperboard is used, it is preferable to use one or more inner ledge panels, such panels 17, 18, to provide added thickness and strength for the ledges.
FIG. 8 illustrates the use of the carton in a traycarrying rack. Such racks usually comprise a frame structure consisting of a number of braced vertical beams 40 which support a plurality of horizontal guide runners 41 on which the trays are slidably mounted within the rack. As shown in FIG. 8, the carton of this invention is supported in the rack by the exterior ledges 42 of the carton resting on the runners 41. This arrangement allows the. cartons to slide along the runners while at the same time they are guided to move in a fixed direction.
