BROWN, OF HUNTINGTON PARK, AND GEORGE IF. FORD, 0]? LOS ANGELES, CALIFORNIA, ASSIGNORS TO I FIBBE'BOARD PRODUCTS INC., 013 SAN FRANCISCO, CALIFORNIA, A CORPORATION OF DELAWARE CARTON Application filed July 6,

The invention relates to cartons, and particularly to folding cartons made from fiberboard and the like.

One of the objects of the invention is the provision of a carton .in which the bottom is supported on flanges running along the lower ed es of the carton.

other object of the invention is the provision of a folding carton made up from a single sheet of fiberboard or similar material,- and in which the supporting flanges, along the bottom edges are formed by the union of adjacent portions of the side and bottom.

Another object of the invention is the provision of a folding carton of such shape as to permit the circulation of air about the bottom and top when alone or when stacked with other similar cartons.

Our invention possesses other objects and valuable features, some of which will be set forth in the following description of our invention which is illustrated in the drawing forming part of the specification. It is to be understood that we donot limit ourselves to the showing made by the said description and drawing, as we may adopt varying forms of our invention within the scope of the claims.

Referring to the drawing: Figure 1 is a plan view of the blank from which the carton is folded up.

Figure 2 is a perspective view of the formed carton, partially collapsed.

In terms of broad inclusion, the device of fiberboard or other suitable material, having integrally formed flanges extending downwardly'from the bottom thereof to provide supports, so that the bottom is raised above 49 the plane on which the carton rests. The

bottom of the carton therefore provides a resilient seat or support for eggs and other articles of fragile nature; and the circulation ofair under the bottom is facilitated. The sides and ends of the cartonare suitably creased to provide inwardly extending folds, so that after. formation the carton may be collapsed into a flat package for storage and shipment. When the carton is set up and filled with eggs, which are preferably sepa- 1929. Serial No. 376,370.

rated by I partitions of fiberboard in the 2 prises a single sheet of fiberboard, cut by suitable dies in the form indicated in Figure 1 of the drawing, and creased and folded as indicated by the dotted lines of the figure.

The blank shown comprises the area 3 forming the bottom of the box, the areas 4 and 6 comprising the front and rear sides, the areas 7 and 8 comprising the ends, and the area 9 comprising the top.

The sides are provided with tabs 11, pref-- erably secured by adhesive to'the end areas as shown in Figure 2; and the top is provided with a flap 12, adapted to be tucked into the package after the contents are'placed therein. Each of the end areas 7 and 8 are creased along the lines 13 so that they tend to fold inwardly, as shown in Figure 2; and similar creases 14 are provided adjacent the ends of the front side 4 of the carton, so that by the united action of these creases, the front may be folded down against the bottom, the ends in upon the front, and the rear and top down over all, making a fiat package for storage and shipment.

The bottom edges of the sides are indicated I by the lines. 16; the material being creased along these lines and folded back to f the line 17, where it is again creased; the fold however being in the opposite direction. The long narrow strip 18 between these two lines 16 and 17, on each side, constitutes a flange folded downwardly from the bottom; and these strips'are preferably adhesively united respectively to those portions of the adj acentsides of similar area and with which they contact whenthe material is creased along the line 16. The adhesive union of the two strips forms a relatively heavy and stifl flange having the necessary strength for its function.

- Thus a heavy flange is formed at the lower edge of the side and underlying the bottom.

Whenthe carton is fully opened, as sug 1D i straightens out into the plane of the bottom.

a In the two-by-six size illustrated, the flanges along the two long sides of the carton are quite suflicient to perform the function desired, but it is obvious without special illustration that similar flanges could be provided across the ends of the carton if made in a three-by-four size.

Our carton is customarily used with a filler of any desirable type; and when so.

equipped an individual pocket is provided for twelve eggs, the springiness or resiliency of the bottom preventing injury under any ordinary handling. Since the bottomof the carton is raised from the plane of the support air maypass freely under it so that refrigeration o the stacked cartons is facilitated.

We claim:

1. A foldable collapsible carton formed of a single blank and having bottom, end and side walls, the portions between said bottom and side walls only being provided with double crease lines, said bottom and side walls being reversely folded on said crease lines when the carton is set up to provide depending anges of double thickness of material formed by longitudinal legs integral with the side and bottom walls and extending only along the sides of the carton, so as to elevate the bottom and provide an unobstructed passageway under the bottom between said flanges, the legs of said flanges being secured together to form rigid extensions of said sides, and said ends and one of said sides being provided with creases whereby both of the sides and ends fold inwardly to fiat collapsed position and outwardly to set up position without bending the flanges which form rigid extensions of the sides, the sides and their respective rigid extensions turning about a hinge line formed by the junction of said flanges with said bottom.

2. A. foldable collapsible carton formed of a single blank and having bottom, end and side walls, the portions between said bottom and side walls only bein provided with double crease lines, said bottom and side walls being reversely folded on said crease lines when the carton is set u to provide depending flanges of double thic ness of material formed by longitudinal legs integral with the side and bottom walls extending only along the sides of the carton, so as to elevate the bottom and provide an unobstructed passageway'under the bottom between said flanges, the legs of said flanges being secured together to form rigid extensions aevaaeo set our-hands,
