s Glalms. (on. ste -1s) This invention relates to an. improvement in paper packages or cartons, suitable for packing fruit. vegetables and the like for shipment and sale, and especially adapted to display the contents of the carton when offered for sale.

In my prior U. S. Patent No. 1,741,369, granted December 31, 1929, it is pointed out that in packages of the character recited above, it is extremely desirable and advantageous to confine the contents of the package under moderate pressure sumcient to cause the cover to bulge more or less, thereby not only firmly securing and preventing injury to the fruit or other commodity thus packaged, but insuring that the cartonwill present a fully and tightly packed appearance when offered for sale, in spite of such shrinkage of the total ful merchandising demands a package having a well-filled, bulged appearance.

This obiectis attained in my aforesaid patent by providing a cover of such design as to provide a mutllatabie display panel adapted to be raised above the outer edges of the cover.

My present invention contemplates and has for an object the provision of an improved carton of the character indicated, capable of being formed from a single continuous sheet ofpaper, and a blank therefor.

A further object of my invention is to provide a carton and blank therefor oi the character indicated, having provision for filling the same from the bottom as well as for'adiusting the interior volume of the carton in a simple and efficacious manner, for ventilating the contents of the carton, for holding the contents securely in-place, and for facilitating face packing. of the carton with fruit of different'sizes and in different quan-' tities.

A still further object of my invention is to provide a carton and blank therefor of the character forth and understood, I now describe, with reerence to the accompanying drawing, a preferred form and manner in which my invention may be embodied and utilized. In the drawing,

Fig. 1 is a plan view of a pre-iormed sheet of paper or blank adapted to be folded to form a carton of the character indicated hereinabove;

Figs. 2 and 3 are bottom elevational and sectional views, respectively, of a carton formed from for the purpose of raising the display panel iii.

Figs. 5 and 6 are plan and sectional views, re- 5 spectively, of a carton formed from the blank illustrated in Fig. 1, Fig. 6 being taken along the lineVI-VI of Fig.5 and illustrating-a modified manner of foldingthe blank of Fig. 1 to provide a closure for the carton; and 10 Fig. 7 is a perspective view of a portion of the carton as illustrated in Fig. 6.

Similar reference numerals designate similar parts in the several views of the drawing.

As will be apparent from the drawing, my carv r, ton is formed from a single continuous sheet of paper of suitable character, having a cover panel A, side panels B, C, D and D, insert flaps E, E,

F and F, and a bottom panel G. I

The cover panel A isdeflned by score lines i, 2, 3 and i, forming a rectangle, the corresponding. sides of which also form sides of the side panels B, C, D and D, respectively. 'Inwardly oi the score lines i, 2, 3 and t, the cover panel A is provided with perforations or cuts 5, 8, i and B which, together with a score line or cut 9, define a mutilatabie display panel ill surrounded by a border or marginal section II, the latter preferably cut away as at it to permit the insertion of a finger The principal corners of the display panel iii are Joined to the corresponding outercorners of the panel A by diagonal score lines it.

' For the purpose of protecting and retaining the contents of the carton when the display panel I0 is thus raised, I provide a sheet it of Cellophane" or other transparent or translucent material, of a size and shape intermediate those of the display panel ill and the entire cover panel A. This window" sheet i6 is attached to 40 that surface of the cover panel Adestined to become an interior surface of the carton, preferably by means of a substantially continuous strip it of adhesive material whichsurrounds the display panel l0. The side panel B adjoining the cover panel A along the score line' i, terminates at score lines If and I8 marking the iunctures of the panel B with the side insert flaps E and E, respectively. Similarly, the side panel C terminates at score lines is and 20 marking the iunctures of the panel C with the side insert flaps F and F, respcctiveiy.

Preferably, the side panels D and D are scpa-' rated from the flaps E andF, and from E and F, respectively, by tapered cuts 22. and the score lines i1 and 18, as well. as it and Ziiyare somewhat convcrgent, thereby providing for a carton of tapered form, as willbe apparent from inspecw tion of the several figures and the descriptive matter hereinbelow.

The bottom panel G adjoins the side panel C along a score line 25, parallel to the score line 2, and while of generally rectangular shape, is preferably provided withdiagonal corner cuts 26, for a purpose to be recited hereinbelow.

. A score line 21 is provided, parallel to and relatively closely spaced from the score line 25. Parallel score lines 28 and 29 are also provided near the opposite side of the panel G. One or more, preferably two, cut-out portions 3| are provided in the panel G, one side of each of which portions 3| coincides with or forms an extension of the score line 28, while the ends of the cutout portion or portions 3| are connected to the score line 29 by cuts 32, preferably although not necessarily, located at right angles to the score lines 28 and 29, thereby. forming a fiap or flaps 33. Preferably, the score line 29 does not extend across the flaps 33, but merely connects the sides of the flaps 33 to the sides of the box and to each other, as shown, so that the flaps 33 are not separated by any score line from that portion of the panel G lying beyond the score line 29.

When my' carton is to be formed and filled, the insert flaps E, E, F and F are first bent at substantially right angles to the corresponding side panels B and C along the score lines l7, |8, l9 and 20, respectively, and the side panels B and C are then bent along the score lines and 2, respectively, to substantially right angles with re spect to the cover panel A until the upper edges of the insert panels E, E, F and F coincide with the score lines 3 and 4. The side panels D and D are then bent along the score lines 3 and 4 respectively, until they meet the insert panels E, F, E and F, and the'panels: D and D are then fastened by means of staples 40 or other suitable fastening means to the adjacent insert flaps E, F, E and F, respectively. The carton is thus formed and ready to be filled.

I have found that the mere act of forming and securing the carton, as hereinabove described, tends to cause the cover panel A to bulge upwardly to some extent, slight bends being made along the score lines l2, thus raising the display panels l above the outer edges of the cover panel A. This bulge is further accentuated, however, when the carton is packed.

In the event that the fruit or other commodities placed within the carton are of sufficient bulk to well fill the carton, the bottom panel G is bent along thescore line 23, the portion of the panel G lying beyond the score line 28 being turned inwardly and placed inwardly of and adjacent to the side panel B, to which it is then fastened by means of staples H or other suitable fastening device. The cut-out portions 3| provide for insertion of a portion of the stapling instrument.

The bottom panel G is so positioned with respect to the remaining portions of the carton that it acts through the medium of the contents of the carton to create or accentuate the bulge in the cover panel, thereby raising the display panel I0 above the outer edges of the cover panel A and giving the carton a well filled appearance. This position is illustrated in Figs. 6 and 7.

In the event, however, the fruit is small or the bulk thereof does not well fill the carton, the bottom panel G is bent sharply along the score line 28 to turn the flaps 33 inwardly of the carton as shown in Figs. 3 and 4. In this instance sufficient bending is permitted at the score lines 21 and 23 to provide for this difference from the position shown in Figs. 6 and '7 and to permit raising or lowering the principal portion of the bottom panel G to such a position as to cause the contents of the carton to be firmly pressed upwardly 5 against the cover panel A.

In this position that portion of the bottom panel G lying beyond the score lines 29 acts as an additional support together with the flaps 33, forming extensions thereof, to maintain the bottom panel 9 in the desi ed position. Staples 4| are used as before, exce t that in this instance these are preferably located in the flaps 33.

It will be noted that with the bottom panel G thus closed and fastened to the' side panel B as at 4|, the beveled corners 26 provide ventilating spaces 42 in the lower corners of the carton which permit circulation of-air and maintain the fruit or other contents in a fresh condition. It will further be observed in Figs. 3 and- 6 that the shape of the cut-out portions 22 provides small ventilating spaces 43 located in the upper-and outer corners of the carton which, while small, are nevertheless adapted to cooperate with the ventilating spaces 42 to permit circulation of air 25, through the contents of the carton.

My carton and the blank from which it is formed are preferably manufactured from paper or fibre of sufiicient strength and rigidity to prevent injury to the contents thereof under the ordinary conditions of shipment and storage, but I prefer to employ what is generally known as double-faced corrugated kraft board.

When the filled, carton is placed ondisplay and offered for sale the display panel ID is readily raised by inserting a finger through the opening l2 between the display panel I0 and the Cellophane window sheet l5 and bending the display panel Ill upwardly along the score line 9. In this manner a prospective purchaser is afforded a good view of the contents of the carton without permitting the latter to become soiled or otherwise damaged.

The display panel l0 may be completely .detached, if so desired, this being facilitated by 45 making the score line 9 of such character as to permit detachment of the panel l0 along the score line Ill as well as along the score lines 5, 6,

If desired, the bottom panel'G may also be provided with a ,mutilatable display panel similar to the panel l0, and the same is true of the other sides of the carton, more particularly the panels B and C. Each of said display panels is' preferably provided with a window pane of "Cel- 5.

lophane or other transparent material.

In the event that several of the sides of th carton are thus provided with mutilatable display panels, I may provide a single panel of Cellophane" and the like, which panel may cover substantially the entire blank, thereby forming in substance, when the carton is formed and the display panels removed, a Cellophane bag having a structural outer casing supporting the same but not seriously impairing the view of the contents.

While, for packaging fresh fruit and vegetables. I prefer to so form the blank and carton that the latter will be tapered, as shown in the drawing, for many other purposes, a tapered form is unnecessary, and the carton may then be made rectangular in shape.

It will therefore be obvious to those skilled in the art that my invention is susceptible of considerable modification in detafl without de- 7 parting from the essential teaching'thereoi and is therefore not limited to the details of the preferred example given hereinabove by way of exemplification and illustration, but may variously be embodied within the scope of the claims hereinafter made.
