FARQUHAR ms ATTORNE United States Patent 3,403,836 (IOMPARTMENTED CARTON AND BLANKS FOR MAKING SAME Melville T. Farquhar, Bon Air, Va., assignor to Reynolds Metals Company, Richmond, Va., a corporation of Delaware Filed Oct. 18, 1966, Ser. No. 587,557 13 Claims. (Cl. 229-27) ABSTRACT OF THE DISCLOSURE This disclosure relates to an enclosed carton, and a blank for making same, wherein such carton has two compartments one of which may be severed away to leave a fully enclosed container of reduced size.

This invention pertains to cartons and more particularly to enclosed cartons which are compartmented and to such compartmented cartons which are also reducible in size and to blanks for making such cartons, or the like.

Previously proposed compartmented containers utilize comparatively large quantities of structural material to define wall means thereof and such containers are quite complicated to make and assemble. These two factors have contributed in making such previously proposed containers comparatively high in cost.

Accordingly, it is a feature of this invention to provide an improved compartmented container or carton which is of simple construction.

Another feature of this invention is to provide an improved compartmented carton utilizing a minimum amount of structural material to define wall means thereof and thereby provide such a carton at minimum cost.

Another feature of this invention is to proivde an improved compartmented carton of the character mentioned which is also divisible (i.e. reducible) in size.

Another feature of this invention is to provide an improved carton of the character mentioned above which can be made from a single sheet of foldable material and without requiring separate inserts.

Another feature of this invention is to provide an enclosed carton of simple and economical construction and having a plurality of two enclosed compartments provided therein.

Another feature of this invention is to provide a compartmented carton having a pair of parallel spaced apart outside walls and having extension flap means extending from such outside wall which are used to form end wall means at each end of such carton and compartment wall means for insertion therewithin.

Another feature of this invention is to provide an improved compartmented carton having a pair of compartments therein which have individual access means provided in end wall means of such carton.

Another feature of this invention is to provide an improved compartmented carton having two enclosed compartments provided therewithin and having means for severing away wall means defining one of such compartments, whereby upon severing away such wall means the remaining portion of such carton defines a completely enclosed compartment.

Therefore, it is an object of this invention to provide an improved compartmented carton having one or more of the novel features of this invention as set forth above or hereinafter shown or described.

Another object of this invention is to provide improved blanks for making such a carton or the like.

Other objects, uses, and advantages of this invention are apparent from a reading of this description, which proceeds with reference to the accompanying drawings forming a part thereof and wherein:

FIGURE 7 is a perspective view similar to FIGURE 3 particularly illustrating the arrangement of compartment wall means within the reducible carton of FIGURE 6.

FIGURE 8 is a plan view of the blank used to make the carton of FIGURE 6.

While the various features of this invention are hereinafter illustrated and described as being particularly adaptable for providing improved compartmented cartons and compartmented reducible cartons which are particularly adaptable for containing food products therewithin, such as dried fruits, for example, it is to be understood that the various features of this invention can be utilized singly or in any combination thereof to provide such enclosed compartmented cartons for containing products of all types and for other uses, as desired.

Therefore, this invention is not to be limited to only the embodiments illustrated in the drawings because the drawings are merely utilized to illustrate one of the wide variety of uses of this invention.

In the exemplary embodiment of this invention illustrated in FIGURES 1-5 an improved container means such as a compartmented carton is illustrated, as well as an improved blank, shown in FIGURE 5, for making such carton. Carton 20 of this example has a plurality of two enclosed compartments shown at 21 and 22 provided therewithin and has means provided as an integral part thereof enabling individual access to

compartments

21 and 22.

As illustrated in FIGURE 4 of the drawings, carton 20 has the general shape of a parallelepiped and comprises a bottom wall 23, a top wall 24, a pair of parallel spaced apart side walls and 26, and a pair of parallel spaced apart end wall means designated by the numerals and 31.

Bottom wall 23 and top wall 24 both have extension flap means extending from their opposite end edges which are adapted to be suitably folded in position, as will be subsequently described, to define the major portion of end wall means or end wall 30 at one end of carton 20 and end wall 31 at the opposite end of such carton. Cooperating portions of extension flap means extending from bottom wall 23 and top wall 24 are also utilized to define compartment wall means such as a compartment wall designated by the numeral 32 extending within carton 20. Compartment wall 32 in this example of the invention essentially bisects the space within carton 20 and defines the previously mentioned enclosed

compartments

21 and 22 on opposite sides of wall 32.

As seen in FIGURE 1 of the drawings, top wall 24 has an extension flap 33 extending from one of its end edges defined by a score line designated by the numeral 34 and a closure flap 35 extending from its opposite end edge defined by a score line designated by the numeral 36. Extension flap 33 has score means shown as a score line 40 therein which is arranged perpendicular to and extending outwardly from end edge 34 of top wall 24.

Score line 40 defines a laterally extending portion 41 of extension fiap 33 which extends beyond score line 40 and is adapted to be folded within carton 2%) upon folding the base portion of extension flap 33 generally transverse (i.e. perpendicular) to top wall 24. Laterally extending portion 41 comprises the bottom section of the previously mentioned compartment wall 32 provided within carton 20.

In a similar manner as described in conjunction with top wall 24, bottom wall 23 has an extension flap 43 extending beyond a score line 44 defining one of its end edges and a closure flap 50 extending beyond a score line 51 defining its opposite end edge. Extension flap 43 has a score line 45 provided therein in a similar manner as score line 40 in extension flap 33 and score line 45 is arranged perpendicular to and extends outwardly of end edge 44.

Score line 45 defines a laterally extending portion 46 which extends beyond score line 45 and is adapted to be folded within carton upon folding the base portion of extension flap 43 perpendicular to bottom wall 23. Laterally extending portion 46 cooperates with portion 41 of flap 33 to define compartment wall 32 and comprises the top section of such compartment wall.

Closure flaps

35 and 50 each have perforation means comprising a series of rectilinear perforations therein designated by the

numerals

52 and 53 respectively.

Perforations

52 and 53 extend perpendicular to their associated

end edges

36 and 51 respectively and are arranged to enable severing of their

respective closure flaps

35 and 50 in two pieces to provide individual access into each

compartment

21 and 22 of assembled carton 20, if desired.

Bottom wall 23 and top wall 24 each has a

tab

55 and 56 extending beyond its

respective end edge

44 and 34. Each

tab

55 and 56 is folded perpendicular to its associated wall and in effect provides a fastening surface against which an associated closure flap is fastened, as by glue, or the like.

Tabs

55 and 56 thus provide increased strength and rigidity for

end walls

30 and 31 respectively upon fastening such end walls in position.

Each side wall and 26 has a pair of flaps extending from its opposite end edges, see FIGURE 1. Side wall 25 has a pair of substantially

rectangular flaps

60 and 61 extending from its opposite end edges while side wall 26 has a pair of similar

rectangular flaps

62 and 63 extending from its opposite end edges.

Flaps

60 and 62 are adapted to be folded and suitably fastened within the plane of end wall to provide increased strength and rigidity therefor while

flaps

61 and 63 are adapted to be similarly folded and fastened within the plane of end wall 31 to provide increased strength for end wall 31.

The preferred assembly sequence for assembling carton 20 will now be described and is particularly illustrated in a series of views in FIGURES 1-4 of the drawings. Carton 20 is initially assembled to define a tubular structure having open ends and with its various extension flaps extending from opposite ends of its bottom wall 23, top wall 24, and

side walls

25 and 26. Such extension flaps are adapted to be folded to define end wall 30 at one end of carton 20 and end wall 31 at the opposite end.

With carton 20 folded as shown in FIGURE 1,

flaps

33 and 43 are first folded so that their base portions extend perpendicular to their

respective walls

24 and 23. Laterally extending

portions

41 and 46 of

flaps

33 and 43 are then folded about their score lines and in the manner illustrated in FIGURE 3 and suitably fastened together, preferably using suitable adhesive means, or the like.

Portions

41 and 46 thus define compartment wall 32 essentially separating the space within enclosed carton 23 into two

compartments

21 and 22 arranged on opposite sides of wall 32.

To completely form end wall 30, tab 55 is then folded in position followed in folding sequence by flaps 66' and 62 and finally by closure flap 35. Flap 35 is fastened in position by any suitable means, as desired.

End wall 31 is completed in a similar manner as wall 30 whereby tab 56 is folded in position followed in folding sequence by

flaps

61 and 63. Closure flap 50 for end wall 31 is then folded in position and suitably fastened.

Thus, it is seen that the various extension flaps extending from each end of the open ended tubular carton as illustrated in FIGURE 1 are folded into a common plane at their respective end to define end wall 30 at one end of carton 20 and end wall 31 at the opposite end.

Perforations

52 and 53 provided in closure flaps 35 and 50 of

end walls

30 and 31 respectively enable such closure flaps to be severed and thereby provide separate and individual access into

compartments

21 and 22 without tearing apart the entire carton 20.

As seen in the drawings extension flap 33 extends from top wall 24 and defines the inside surface means of end wall 31 while closure flap 50 for such end wall extends from bottom wall 23. In a similar manner extension flap 43 extends from bottom wall 23 at the opposite end of carton 2t and defines the inside surface means of end wall 30 while closure flap 35 for end wall 30 extends from top wall 24. This arrangement assures that carton 20 has higher structural strength enabling various types of products to be carried within such carton.

Extension flaps 33 and 43 have base portions which are substantially identical in configuration and area such that upon folding such flaps in position compartments 21 and 22 are of equal cross sectional area. In addition,

portions

41 and 46 of

flaps

33 and 34 respectively are also of substantially identical configuration and area and cooperate to define compartment wall 32 as previously mentioned.

Closure flaps 35 and 50 with their

perforations

52 and 53 define the outside surface of

end walls

30 and 31 respectively.

Perforations

52 and 53 are provided so as to lie parallel to and immediately adjoining

score lines

45 and 40 respectively in the assembled carton. Thus, it will be appreciated from FIGURE 3 of the drawings that by tearing along perforations 53 and unfastening that portion of flap 50 adjoining side wall 25 easy access is provided into compartment 21. Likewise easy access to compartment 22 is preferably provided by tearing along perforations 52 and unfastening that portion of closure flap 35 adjoining side wall 26. Of course, it will be appreciated that individual access may be provided into

compartments

21 and 22 without following the above suggested access sequence.

The particular arrangements and sizes of the various extension flaps of carton 20 enable the forming of

compartments

21 and 22 which are substantially identical in size and peripheral configuration. It will be appreciated that such extension flaps may be varied as desired to provide enclosed compartments within carton 20 which are of different sizes.

The compartmented carton 20 can be formed in any suitable manner and made from any suitable foldable material. It is preferably formed from the blank 70, illustrated in FIGURE 5. Blank 70 is made of cardboard or the like, having a side such as the exposed surface thereof laminated with metallic foil, such as aluminum-containing metallic foil, or the like, suitably colored, embossed, imprinted, or remaining plain as desired.

Blank 70 is suitably cut and scored and includes a series of parallel rectilinear score or fold

lines

71, 72, 73, and 74 defining the extent in one direction of bottom Wall 23 between

score lines

71 and 72, side wall 25 between

score lines

72 and 73, top wall 24 between score lines 73 and 74, and side wall 26 extending beyond score line 74. An extension flap 75 extends beyond score line 71 and provides a closure flap for carton 20. Closure flap 75 is suitably fastened as by glue, or the like, to side wall 26 to define the open ended tubular structure illustrated in FIGURE 1 of the drawings.

The extent of the various rectangular walls 23-26 in a direction perpendicular to the above described direction will now be described. As seen in FIGURE 5 of the drawings, bottom wall 23 has a pair of opposite end edges defined by

score lines

44 and 51 respectively, side wall 25 has a pair of opposite end edges defined by a pair of score lines 76 and 77, top wall 24 is defined by

score lines

34 and 36 at its opposite ends, and side wall 26 is defined by a pair of score lines 80 and 81 at its opposite ends.

Blank 70 has a plurality of

flaps

63, 33, 61, 56 and 50 defined therein along one end portion and such flaps are adapted to be folded into a common plane to define end wall 31.

Extension flap '63 is defined by score line 80 at its base portion and by an elongated rectilinear cut 83 extending perpendicular to the inner end of score line 80 and generally in line with score line 7 4.

Extension flap 33 is defined by score line 34 at its base portion, an angled cut 86, and its opposite side edges are defined by elongated cut 83 at one side and an elongated rectilinear cut 84 at its opposite side generally extending in line with and outwardly of score lines 73. Flap 33 has an extension portion 41 which extends laterally beyond score line 40 provided therein and arranged to extend perpendicular to score line 34.

Flap or tab 56 is defined at its inner edge or base portion by score line 34 and its outer periphery is defined by

cuts

84 and 86.

Extension flap 61 is defined by score line 76 at its inner end and its opposite edges are defined by cut 84 at one edge and another rectilinear cut 85 at its opposite edge. Cut 85 is arranged perpendicular to one end of score line 76 and extends in line with and outwardly of score line 72.

Closure flap 50 is defined by score line 51 at its inner end and by rectilinear cut 85. A series of rectilinear perforations also referred to as a perforation line 53 is provided in extension flap 50 essentially bisecting such flap and perforation line 53 is arranged perpendicular to score line 51 as illustrated.

In a similar manner as described in connection with end wall 31, blank 70 has a plurality of extension flaps 62, 35, 60, 43, and 55 provided therein along its opposite end portion and such flaps are adapted to be folded into a common plane to define end wall 30.

Extension flap '62 is defined by score line 81 and by an elongated rectilinear cut 90 extending perpendicular to the inner end of score line 81 and arranged to extend in line with and outwardly of score line 74.

Extension flap 35 is defined by score line 36 at its inner end edge, by cut 90 defining one side edge and another cut 91 defining its opposite side edge. Cut 91 is arranged to extend in line with and outwardly of score line 73. A series of rectilinear perforations or perforation line 52 is provided in extension flap 35 essentially bisecting such extension flap and arranged perpendicular to score line 36.

Extension flap 60 has a score line 77 defining its base portion, cut 91 defining one edge, and a cut 92 defining its opposite edge.

Extension flap 43 is defined by score line 44 at its inner end, by cut 92 along one edge, and by an angled cut 93. A score line 45 is also provided in extension flap 43 defining flap portion 46 extending beyond score line 45.

The small flap or tab 55 is defined by score line 44 at its base portion and by angled cut 93 at its outer end.

Thus, it is seen from the above description that carton 20 utilizes a plurality of extension flap means which are provided therein in an efiicient manner without unnecessary duplication of the various wall means to thereby provide carton 20 at a very low cost as compared with previously proposed compartmented containers. The structural arrangement provided also assures that a compartmented carton of high strength is provided.

Another exemplary embodiment of this invention is illustrated in FIGURES 68 of the drawings. In the embodiment of FIGURES 68 the illustrated carton and blank from which it is made are practically identical to carton 20 and associated blank 70 previously illustrated and described. Therefore, the carton of this latter embodiment will also be designated by the numeral designation 20 followed by the letter designation A and the associated blank shown in FIGURE 8 will be designated by the numeral 70 followed by the letter designation A. Corresponding practically identical components of carton 20A and blank 70A will also be designated by the same numerals as previously also followed by the letter designation A and not described again. The only changes in carton 20A which make it different from carton 20 are changing the position of two of the flaps provided therein and adding perforations in its bottom and top wall. Such perforations will be designated by new numerals also followed by the letter designation A.

Exemplary carton 20A has a pair of completely

enclosed compartments

21A and 22A arranged therein on opposite sides of its compartment wall 32A. In addition to being compartmented, carton 20A is also divisible into two parts essentially by severing along perforation means provided in wall means immediately adjoining the entire peripheral edge of compartment wall 32A. Thus, carton 20A is divisible (i.e. reducible) into two substantially equal volume parts corresponding to the volume of

compartments

21A and 22A.

As seen particularly in FIGURE 8 showing blank 70A from which carton 20A is made, bottom wall 23A has perforation means shown as a series of rectilinear perforations A provided therein which extend completely thereacross. Perforations 100A are arranged substantially in line with score line 45A at one end and perforations 53A in closure flap 50A at its opposite end. In a similar manner top wall 24A has a series of rectilinear perforations 101A provided therein which extend completely across such top wall and are arranged substantially in line with score line 40A at one end and with perforations 52A provided in closure flap 35A at its opposite end.

Thus, upon folding blank 70A to form carton 20A as illustrated in FIGURES 6 and 7 of the drawings, it will be seen that

perforations

52A, 101A, 53A, and 100A are positioned immediately adjacent the peripheral edge of compartment wall 32A and as previously mentioned this enables carton 20 to be severed into two equal volume sections.

One of such sections, illustrated in this example as the section comprising compartment 21A, remains completely enclosed upon severing carton 20A in two. This feature makes it possible to first use the product within compartment 22A until it is exhausted and then sever away the outside wall means defining such compartment thereby leaving compartment 21A intact and with its product completely enclosed.

Carton 20A thus provides an inexpensive and easily formed compartmented container which is useable, in effect, as a dispensing container which can be reduced to half its original size once the product has been removed from within compartment 22A. Of course, the resulting reduced size package uses less storage space and is easier to handle.

The manner of providing the various fiaps in this exemplary embodiment of the invention is such that onehalf of carton 20A may be severed away. However, the flap arrangement could be easily changed so that any desired fractional portion of carton 20A could be severed away in a similar manner.

A comparison of blank 70A shown in FIGURE 8 of the drawings with blank 70 shown in FIGURE 5 will show that flap 33A with its terminal outwardly extending portion 41A is turned to extend in a directly opposite direction from the corresponding flap in blank 79. Accordingly, flap or tab 56A is also positioned to correspond to the arrangement of extension flap 33A with its laterally extending portion 41A. This change in the arrangement of

flaps

33A and 56A does not require that a detailed description be made of the various cuts and

scores defining flaps

33A and 56A and the previous description in connection with blank 70 is also fully applicable in this latter instance.

As seen particularly in FIGURE 7, extension flaps 33A and 43A are fastened to carton 20A so that their base portions are connected to the same end portion of such carton, i.e. adjacent side wall 25A. Upon folding portions 41A and 46A of

flaps

33A and 43A respectively within carton 20A compartment wall 32A is integrally fastened to the end portion of carton 20A defining compartment 21A. Thus, upon severing away compartment 22A as previously described, the remaining compartment 21A is retained as a completely closed package occupying one-half of the space previously occupied by carton 20A.

Blanks 7t) and 70A are each preferably made from a single piece of foldable material and are substantially rectangular in peripheral outline. Such blanks utilize the blank material in an efficient manner so that there is practically no waste and so that every component portion of the blank is utilized without unnecessary duplication or unnecessary overlapping of adjoining wall means. Also, the simplicity of

blanks

70 and 70A enables each of them to be easily and readily formed using suitable conventional cutting and scoring equipment thereby providing such blanks at minimum cost.

As seen particularly in the assembly sequence illustrated in greater detail in connection with carton 20, it will be appreciated that carton 20 as well as carton 20A are easy to assemble. Therefore, it may be desirable in some applications to ship

blanks

70 and 70A in their flat form shown in FIGURES 5 and 8. However,

such blanks

70 and 70A may be partially assembled by fastening their

respective flaps

75 and 75A in position to thereby define tubular enclosures in each case having open ends essentially as illustrated in FIGURE 1 of the drawings. Each partially assembled

carton

20 and 20A may then be collapsed or flattened from its tubular form and shipped in such flattened condition to the user thereof for assembly and insertion of a product therewithin. The manner of assembly is, of course, very simple and was illustrated and described previously.

Terms such as inwardly, outwardly, bottom wall, top wall, side wall, end wall, and the like, have been used throughout this disclosure for ease of description and merely to correspond to the arrangement of various wall means as shown in the drawings and such terms should not be considered as limiting the scope of this invention in any way.

Thus, it is seen that an improved compartmented carton has been provided by this invention which is of simple and economical construction, which provides individual access to each of its compartment means, and which can be readily assembled without requiring special equipment.

In addition, this invention provides such a compartmented carton which is also reducible in size.

Further, this invention provides improved blanks for making such compartmented cartons, or the like.
