13 Claims. (Cl. 229-33) ABSTRACT F THE DISCLOSURE A unitary carton comprising `side walls, end walls and cover flaps. Two spaced partitions are located centrally of the carton and are attached to the side walls lby aps. Flaps extending from the end walls are joined to the side Walls. The portions of the side walls and bottom wall vbetween the partitions are severable to transform the unitary carton into two separate complete cartons.

This application is a continuation of parent application Ser. No. 576,590, tiled on Sept. 1, 1966.

This invention relates to paper boxes and more particularly to an improved carton possessing certain advantages over known types of cartons for packing fruit and vegetables.

The advantages of the carton of this invention may best be understood when one considers by way of example the problems involved in the shipping of bananas in foreign commerce.

One method of shipping bananas from the country in which they are grown to other nations, is to pack them in hands separated from the :stern in cardboard boxes provided with openings yfor ventilation. It is the custom of different countries to import the resulting hands of bananas at certain weight. Thus, importers of the United States of America usually import the hands of bananas in about forty pound lots, whereas the importer in European countries usually buy the bananas in about twentyfive-pound lots. This heretofore necessitated that the exporter carry in stock cartons of different sizes to satisfy the requirements of the different countries to which the bananas are shipped.

It is the primary purpose of the present invention to provide a carton which can be employed to ship fruit and vegetables, as -for example bananas, in lthe larger quantities required by certain countries, and yet can be readily adapted to the shipment of such products in the smaller quantities customary with other countries.

Another object of the invention is to provide an irnproved fruit and vegetable box construction which can successfully withstand the crushing stresses to which this type of box is subjected in the stacking and handling thereof during shipment of the product.

A further object of the invention is to provide an improved fruit and vegetable carton construction that will provide maximum ventilation for the product when such catrons are piled in multiple stacks closely arranged together.

A still further object o-f the invention is to provide an improved banana box construction which is less expensive to manufacture, can be more readily assembled and is easier to open than known boxes of this type.

A better understanding of the invention will be obtained from the following description when read in connection with the accompanying drawings, in which:

FIG. 1 is a perspective View showing a carton embodying the invention in opened condition;

FIG. 2 is a similar view showing the carton closed;

C 3,392,904 ce Patented July 16, 1968 FIG. 3 is a plan view of the cardboard blank from which the body of the carton is formed;

FIG. 4 is a plan view of the cardboard partition blank;

FIG. 5 is a horizontal sectional vie-w through one of the cover llanges; and

FIG. 6 is an end view of a group of stacked cartons embodying the invention.

In the drawings, the numerals 10 and 11 designate the side walls of the carton, the

numerals

12 and 13, the end walls of the carton, and the numeral 14 the bottom Wall of the carton. As is shown more clearly in FIG. 3 of the drawings, the aforesaid walls are formed from a single piece lof cardboard and are separated from each other by suitable creases formed in the blank. The cardboard is preferably of the type in which a central corrugated layer of paper material is sandwiched between two plain layers of such paper material to provide a relatively stiff paperboard. The side walls 10 and 11 of the carton and the bottom wall 14 thereof are provided with ventilation `openings 15 which are preferably symmetrically arranged with respect to a transverse median plane indicated by the dotte-d line 16 in FIGS. 1-3 of the drawings.

Hingedly connected by creases to both side edges of the

end walls

12 and 13 are aps 12', 12" and 13', 13", respectively, of equal length. The aps 12', 13' overlie the interior surface of the side wall 10, and the

llaps

12, 13" overlie the interior surface of the side wall 11. It will be noted that the length of the flaps 12', 12", 13', 13" is less than one-half the length of the side walls 10 and 11 so that the ends of such flaps are spaced a substantial distance from the transverse centerline 16 of such side walls. The length of such aps, however, is sufciently great to overlie the major portion of one-half of such `side walls, as is shown in FIG. 1 of the drawings. The flaps 12', 12", 13' and 13" are provided with openings 15 which register with the openings 15 in the side walls 10 and 11.

The carton is divided at its center by two transverse cardboard partitions 17 and 18. The partition 17 is provided with end llaps 17', 17", the former of which, as is shown in FIG. l, overliesthe interior surface of side wall 10 and the latter of which overlies the interior surface of side Wall 11. The ap 17' is disposed in the same plane as and in opposed relation to the tlap 12', and the flap 17" is disposed in the same plane as and in opposed relation to the flap 12". It will be noted that the

flaps

12', 17 and 12", 17" substantially cover the areas of such side walls 10 and 11, respectively, between the partition 17 and end wall 12. Similarly, the partition 18 is provided with end aps 1S', 18 overlying the interior surfaces of the side walls 10 and 11, respectively, and disposed in the same planes as and in opposed relation to the

aps

13 and 13", respectively. The flaps 13', 18' and 13", 18" substantially cover the areas of the side walls 10 and 11, respectively, between the partition 18 and the end wall 13. The side wall 10 is provided with top ilaps 10', 10", the former of which overlies the upper portions of the llaps 12', 17' and the latter of which overlies the upper portions of the flaps 13', 18'. Similarly, the side wall 11 is provided With top flaps 11', 11", the lformer of which overlies the upper portions of the aps 12", 17" and the latter of which overlies the upper portions of the flaps 13", 18". The aforesaid flaps of the side walls 10 and 11 are each secured at its ends by two staples 19 to the top portions of the associated end wall and partition flaps and side Wall halves, which staples secure the

end walls

12 and 13, the partitions 17 and 18, and the side walls 10 and 11 in properly assembled relation.

It will be noted that the partitions 17 and 18 are in spaced relation and that the arrangement of the afore- 3 said flaps is such that partition 17, end wall 12 and the a-ssociated halves of the side walls 1t) and 11 form one complete separate container, and that partition 18, end wall 13 and the associated other halves of the side walls and 11 form another com-plete separate container. The two containers are integrally connected together by the portions of the side walls l@ and 11 and the bottom wall 14 between the two partitions 17 and 18. The partitions 17 and 18 are preferably spaced apart a distance equal to the thickness of the flaps or ilanges of the two covers 20, 21 so that the outer end sections 20', 21 of such ilaps or flanges will tit snugly therebetween. It will also be noted from FIG. 4 of the drawings, that the two partitions 17, 18 are formed from a single blank and are integrally joined by a spacing section 23 which seats on the bottom wall 14. This spacing section 23 and the staples 19 secured to the flaps of the partitions 17 and 18 maintain such partitions properly spaced throughout their en tire areas. The central connecting portions of the side walls 10 and 11 between the spaced partitions, are provided at their upper ends with

slots

22, 22, each having vertical edges spaced apart a distance equal to the spacing between the partitions 17, 1S, and a depth approximately equal to the width of the end sections 20', 21 of the cover flanges. The upper ends of the side edges of the

slots

22, 22 are beveled to facilitate the insertion of the cover flange end sections 20', 21 into such slots. It will be noted also that the associated upper portions of the side wall flaps 10', 19, 11' and l1 are also beveled to conform to the shape of the entry end of the

slots

22, 22.

The

covers

20 and 21 are integral with and hingedly connected to the

end walls

12 and 13, respectively. Each cover is provided with an integral, rigid flap or flange which by its construction remains in assembled relation without the aid of any additional fastening means. The end and side sections of the flap or flange on cover 2t) are designated generally by the reference numerals 20', 20" and 20"', and the end and side sections of the ange on cover 21 are designated generally by the

reference numerals

21', 21 and 21". It will be noted from a comparison of FIGS. 3, 5 and 6 of the drawings that the

side flange sections

20, 20', 21 and 21' are each cornposed of an intermediate ap 25 hinged to the body of the cover blank and an outer flap 26 hinged to the intermediate ap 25, the two flaps being folded inwardly on each other as shown in FIGS. 5 and 6. The end flange section 20', 21 are each composed o-f an intermediate ap 27 which is hinged to the body of the cover blank and an outer flap 28 hinged to such intermediate flap, the two flaps being folded inwardly on each other as indicated in FIGS. l and 5. The intermediate flaps 27 are each provided with end flaps 29, 29 which are located between the folded

aps

25, 26 of the associated side flange sections (note FIG. 5). It will also be noted from FIGS. 1 and 5, that the

outer aps

26, 26 of the two side flange sections of each cover are locked in folded position by the outer flap 28 of the associated end flange section, thereby maintaining all of the flange flaps of each cover in such assembled relation as to provide a rigid cover flange.

It will be understood yfrom the foregoing that the two integrally connected separate containers formed from the single body blank and the single partition blank, may both be lled and closed by their

covers

20, 21, and utilized as a single, unitary container for shipment of the content thereof. The hingement of the two covers on the ends of the unitary container makes for easy access to its two compartments and the ready opening and closing of such compartments. As is shown in FIG. 2 of the drawings, in the closed condition of the unitary container the end ange sections 20', 21 of the covers will be inserted between the partitions 17, 18 and into both the

slots

22, 22, the

side flange sections

20, 21" overlying the outer surface of the side wall 10, and the side ange

sections

20 and 21 overlying the outer surface of the side wall 11.

The end ange sections 20', 21' snugly tit between the partitions 17, 18 and in the

slots

22, 22 so that the

covers

20, 21 will be elfectively locked in closed condition by the coaction of such parts. If it is desired to make the single unitary container into two separate containers either at the place of shipment, or at the place of delivery, this may readily be accomplished by cutting the side walls 10 and 11, the spacing section 23 of the partition blank, and the bottom wall 14 along the dotted line 16 in FIGS. 1-3 of the drawings. When such cut is made, there will result two separate complete containers each capable of holding one half the quantity of product capable of being held by the unitary container from which they were formed. The region of cut may be better defined by securing two staples 19' to the `bottom portions of the partition flanges 177 17, 18 and 18" (see FIGS. l and 2). The addition of these staples 19' will also further increase the stability of the structure of 4the carton. The line of cut may also be made more definite by printing lines on the side and bottom walls of the carton coincident with the dotted line 16.

The cardboard material of the

end walls

12 and 13 of the unitary container are cut to provide two

hand holes

30, 30 by which such container may be carried and which also functions as ventilation holes for the product. Preferably also, the partitions 17, 18 are provided with sirnillar hand hold openings 31, in FIG. 4, to provide ventilation through the length of the unitary carton and to provide hand holds for the divided cartons. The

covers

20 and 21 are also provided with ventilation holes 15" which may be arranged, as illustrated, to be aligned with the ventilation holes 15 provided in the bottom wall 14 of the carton when the covers are closed. As a result of such ventilation holes, and the construction of the covers, there is provided ample ventilation for the product when such cartons are in stacked relation. It is usual in the shipment of such cartons to place stacks of about eight or ten thereof closely adjacent of one another to form a row of stacks. As is indicated in FIG. 6 of the drawings, when the cartons of this invention are so stacked, the relatively thick side ange

sections

20, 20"', 21, 21'" will cause substantial spacings 32 to be formed between the cartons in adjacent stacks. These spaces 32 are Suthciently wide, at least one-half inch, to provide for adequate ventilation through the ends of such spaces and through the openings 15 in the side walls of the cartons. It will be noted also that in such stacked relation of the cartons, the increased strength afforded them by the end wall flaps 12, 12, 13', 13, the partition flaps 17', 17", 18' and 18, the partitions 17, 18, and the association with the latter of the rigidified cover flanges, will prevent destruction of the cartons under the crushing stresses they will be subjected to during shipment.

While I have hereinabove described and illustrated in the drawings, a preferred embodiment of my invention, it will be apparent to those skilled in the art that various changes may be made therein without departing from the spirit of the invention or the scope of the appended claims.
