United States Patent This invention relates in general to new and useful improvements in the construction of can carriers, and

more specifically relates to a novel can carrier of the wrap-around paperboard type.

At the present time, there are in use can carriers of the wrap-around paperboard type wherein the side walls of the can carrier are provided with openings along the fold'lines along which the side walls are connected to top and bottom walls of the can carrier, the openings being for the purpose of receiving the seams of cans to locate the cans within the can carrier, and the material struck from the side walls in the formation of the openings therein remaining integral with the top and bottom walls and projecting outwardly beyond the side walls to provide supports for the seams of the cans. Since the openings are disposed along the fold lines of the can carrier, the can carrier is subject to rupture along the fold lines due to the outward directed pressure on the fold lines by the seams of the cans. As a result, in instances rupture occurs along the fold lines to the extent that the endmost cans in particular are dislodged accidentally from the can carrier.

In View of the foregoing, it is the primary object of this invention to provide a novel can carrier of the wraparound paperboard type wherein the openings in side walls thereof for receiving the seams of the cans are provided with suitable reinforcing means to prevent the accidentalrupture of the can carrier along the fold lines thereof.

Another object of this invention is to provide a conventional type of can carrier with flaps struck from the walls thereof and folded into a partial overlying relation to the side, top and bottom walls of the can carrier surrounding the openings formed in the side walls of the can carrier so as to reinforce the fold lines of the can carrier at opposite ends of the openings formed in the side walls thereof.

Still another object of this invention is to provide in a conventional can carrier of the paperboard type, flaps which are struck from the top and bottom walls of the can carrier and folded towards the side walls of the can carrier, the flaps being provided with fold lines which, when the flaps are in position, are disposed coextensive with the fold lines of the can carrier and which flaps are aligned with openings in the side Walls of the can carrier so that the flaps engage the seams of the can carrier and serve to reinforce the can carrier in the areas of the openings in the side walls.

A further object of this invention is to provide a novel blank for forming a can carrier, the blank having portions thereof which are cut out and are ready to be struck therefrom to define flaps which will serve as reinforcements for openings formed in the side walls of the can carrier which is formed from the blank.

Still another object of the invention is to provide a can carrier of the customary wrap-around paperboard type with reinforcing flaps which are struck from the top and bottom walls thereof, the reinforcing flaps being foldable out of the planes of the top and bottom walls to positions generally surrounding the openings formed in the side walls of the can carrier to serve as reinforcements for the can carrier in the vicinity of the side wall openings, the flaps being disposed in alignment with only the endmost ones of the side wall openings,

"ice

and each of the flaps being provided with an edge portion for engaging the seam of a central can to restrict the outward movement of the central can and thereby resist the tearing force of a central can on the can carrier along a fold line thereof.

A still further object of this invention is to provide a novel can carrier of the customary wrap-around paperboard type wherein the can carrier is provided with suitable reinforcing means to prevent the rupture of the can carrier along the fold lines thereof, the can carrier being of the type having openings in the side walls thereof for the reception of seams of cans, and the reinforcing means being in the form of a centrally located flap aligned with each central opening of the can carrier, and the flap being provided with edge portions for engaging the seams of next adjacent cans to prevent inward movement of the cans, and the can carrier being further provided with edge flaps for engaging the seams of the outermost cans to resist outward movement thereof, whereby the can carrier is reinforced against tearing along the fold lines thereof due to pressures exerted thereon by cans disposed therein and projecting through the side wall openings.

With the above, and other objects in view that will hereinafter appear, the nature of the invention will be more clearly understood by reference to the following detailed description, the appended claims and the several views illustrated in the accompanying drawing.

FIGURE 12 is a plan view of the blank from which the can carrier of FIGURE 9 is formed.

Reference is now made to the drawings in detail, where in the specific features of embodiments of the invention are illustrated. In FIGURES 1 through 4, inclusive, there are illustrated the details of a can carrier, generally referred to by the numeral 15. six conventional cans C which are provided at the oppo- The can carrier carries site ends thereof with chimes or seams S. The details of the construction of the can carrier 15 are best understood by reference to' the details of ablank from whichthe can carrierJ'lS is formed, the blank being generally referred The blank 16' is best illustrated in FIGURE 4, and is generally of an elongated rectangular outline. For the most part,the blank 16 is of a conventional construction, but incorporates the novel details of the present invention.

Accordingly, all of the specific'details of, the will not be specifically described here.

The'bla'nk 16' is provided with a first terminal fold line 17 which sets ofl? atone end of the blank 16 a bottom 1 formingpanel 18'. A similar fold line'19 is disposed adjacent theopposite end of the blank 16 and sets oif a terminal bottomforming panel 20. The

panels

18 and 20 combine to define a bottom wall 21 of the can carrier15. In order to connect together the bottom forming panels 1 8 "and 20, the panel 20 has projecting therefrom a plurality of locking tabs 22 which are hingedly connected to the edge of the panel 20 and which are engageable in openings 23 formed inthe panel 18. Thelocking tabs22 also passthrough slits 24 in thepanel 18, the slits.24 being formed in the outlining of tabs 25 which are hingedly connected to the panel 18 alongfold lines 26. Thetabs 25 project upwardlyfrom the bottom wall 21 for engagement between the cans of the two rows ofcans C in the manner best illustrated inFIGURE 3.

' The blank 16 is provided with a second set of

transverse fold lines

27 and 28 which correspond to the

fold lines

17 and 19. V The area of the blank 16'between the

fold lines

27 and 28 is inthe form of a top wall 29 of the can carrier 15 while the area of the blankj16 between

thefold lines

17 and 27 is in the form of a side wall 30 and the portionof the blank16 between the fold lines. 19

and 28 is in theforin of a side wall 31.

f Each ofthe

foldlines

17, 19, 27 and 28 is interrupted by a generally C-shaped cut 32 which is formed within the associated

side wall

30, 31. A slit 33 intersectse'ach of the Q-shaped cuts 32 andextends along the respective side wall 3%, 31 in a direction lengthwise ofthe blank 16. In

. the completed can carrier, each C-shapedcut 32 results in the formation of an opening 34 in the

respective side walls

30, 31, and a projection 35 on either the bottom wall 21 or the top wall 29. This is best shown inFIGURES 1 and 2. The purpose Oftheopenings 34 isto 'perniitthe seams S of the cans C to projectthroughthe

side walls

30,31 and to interlockthe cans C with'thecan carrier 15 s'o'as to prevent movement of the cans C relative to the can carrier .15. -The slits 33 provide for the outwardexpansion of the

side walls

30, 31 wherever inecessary.

, The top wall 29 ofthe blankl16isfprovided with a plurality of cut lines 36 which, together with associated foldjlin'es 37, define tabs 38 which, in the formation of the can carrier 15, depend intoithe, interior' o'f the can carrier 15 and extend between 'adj'a cent upper seams S of adjace'nt'cans, as is best shown inQFI GURE 2.

The top wall 29 of theblank 16'i s also proyided with a pair of oppositely facing,fgenerally C -shaped cut1ines. 39 which, together withffold linesi40, define p'ush-outs'41 I which may be pushed downwardly into the interidr of the can carrier 15 tofd efine finger-receiving openings 42 (FIG- URE 1) whereby onesfingersma'y beplacedthrough'the 7 top wall 29 of the can and carrying of the filled can carrier 15.

carrier, 15, to facilitate the lifting The foregoing featuresfof the blank 16 and the can carrier 15 whichisf'formed from the blank .16, are known in other blank constructions invented by me" However, the

can carrier 15has atendency to tear or rupture air ng the v4 foldlines .17, 19, -2 7 and',28 due'to the, pressures exerted on the portions of thesefoldlinesfby thecans'Ctherein.

This pressure is not a static pressure, but is one ,which A developed during thelcairying and handling of the filled can carriers 15. The cans C, when the can carriers 15 are fmov'ed, have a tendency to shift relative to the can carrier 15. This resistance against shifting is prevented only by the interlocking of the cans with respect to the can carrier 15, with the result that the pressure is exerted on the can carrier 15 principally along the fold lines 17,19, 27 :and 28 with a tendency to rupture the fold lines at the ljopenings 34. The present invention has to do withthe reinforcing of these fold lines.

The top wall 29 of the blank 16 is provided with a plurality of generally C-shaped cuts 43 which face respective ones of the C-shaped cuts 32. Each of the C-shaped cuts 43 terminates ina fold line 44 which is disposed parallel to a'respectiveone of the fold lines- 27 and 28. The

bottom forming panels

18 and 20 are provided with like 0- :shaped cuts 43 which terminate in fold lines'44 which are l disposed parallel to the fold lines- 17 and. Each 6- :s'haped'cut 43, together with each fold line 44, defines a flap, generally referred to by the numeral45.

Each flap 45 is providedwith a C-shaped cut 46 which is disposed in partconcentric with its associated C-shaped cut 43.' The 'endsof the C-shaped cut 46 terminate in fold lines '47, which in turn, terminate at the C-shaped cut 43I Thus, each C-shaped cut 46 and thefold lines 44 associated therewith divide each flap; 45 into two flap portions 4'8 and 49 as is best shown in FIGURE 3. The flap portion 45 is connected to therespective portion of the can carrier 15 while the flap portion 48 is carried by the flap portion 49. i

Considering now FIGURE 3 in detail, it will be seen that when the flap 45 illustrated therein is folded to its can carrier reinforcing position, the fold lines 47 thereof are disposed coextensive with the fold line 19 in the illusc'tration. The flap portion 49 overlies the bottom forming 'panel 20 and the flap portion 43 is disposed in opposed relation to the inner surface of the side wall'31. As a result of the C-shaped cut 46in the flap 45, an opening 50is formed in the flap portion 48, the opening 50 being aligned with a respective one of the openings 34,. Also,

a projection 51 isformedon the flap portion 49, which projection 51 projects, through the aligned openings 50 and'34 and overlies the associated carrier 15 has been wrapped therearound in the conventional manner. Each 'flap 45 extends entirelyabout its associated opening 34 and provides a double thickness of material along its associated one of the fold lines 17, 19, 27 and 28. Therefore,the flaps 45 serveto suitably reinforce the can carrier 15. All of this is done without the requirement of additional material in the formation of the blank 16.

Reference is now made to FIGURE 5 in particular, wherein a can carrier, generally referred to by the numeral 60, is illustrated. Thecan carrier'60 holds six cans C, the cans C being of a conventional type, such as a 'conventional beer can, and having chimes or seams S at opposite ends thereof. The can carrier 6t} is formed from a blank 61'.

I The blank 61 is illustrated in FIGURE 8, and is formed of a paperproduct, such as paperboard. The blank 61 has anelongatedioutline and the outline of the blank 61 is identical with that of the blank 16. Further, the basic details ofthe blank 61 are the i 16: and will therefore be. identified bylike numerals. Therefore, the can carrier has same as those of the blank a bottom wall 21 which I is formed of overlapped and interlocked bottom

wall forming panels

18 and 20,

side walls

30 and 31, and a [he can carrier 60 differs from the can carrier 15 in the means provided for reinforcing the same along the various fold lines between the top and bottom walls and the side walls. The top panel 29 and the

bottom forming panels

18 and 20 are each provided with flaps, generally referred to by the numeral 62. Each flap 62 is bounded by a fold line 63 and a cut line 64 which are disposed in parallel relation and are parallel to the fold lines 17, 19, 27 and 28, with the fold lines 63 being disposed adjacent to the respective one of these fold lines. The outer ends of the fold lines 63 and the cuts 64 are connected together by a C-shaped cut 65. A concave cut 66 is disposed at the inner end of the fold line 63 and a similar concave cut 67 is disposed at the inner end of the cut 64. The adjacent portions of the

cuts

66 and 67 are connected together by a cut line 68. Thus, each flap 62 may be folded out of the plane of its respective portion of the can carrier 6t).

Each flap 62 is provided with a C-shaped cut 69 which is aligned with and opposes the associated one of the C-shaped cuts 32. The ends of the C-shaped cut 69 are connected to the ends of the flap 62 by an interrupted fold line 70.

It is to be noted that the flaps 62 are aligned only with the outermost ones of the openings 34. Thus, the flaps 62 serve only to directly reinforce the outermost openings 34. This is accomplished by folding each flap 62 so that a portion 71 thereof overlies or underlies its respective top or bottom wall of the can carrier 60, and a second portion 72 thereof is disposed in face-to-face relation with respect to the respective one of the side walls 30', 31. This is best shown in FIGURE 6, for example. In the folding of the flap 62 to define the two flap portions 71, an opening 73 is formed in the flap portion 72 in alignment with a respective one of the openings 34. In a like manner, a projection 74 is formed on the flap portion 71 in alignment with a respective one of the projections 35. The flap 74 extends through the aligned

openings

34 and 73 and is aligned with its respective projection 35.

The flaps 62, being aligned with only the outermost ones of the openings 34, serve to directly reinforce the can body 62 in the vicinity of these outermost openings. However, the flaps 62 also serve to indirectly reinforce the can carrier 69 in the vicinity of the central openings 34.

In the formation of each flap 62, the cut 66 forms a curved edge 75 at the inner end of the flap portions .71. The position and curvature of this curved edge corresponds to the position and curvature of the seam S of an associated central can C, as is best shown in FIGURE 7. Since the two flaps 62 along each line of cans C combine to engage the seams "S on opposite sides of the center can C, it will be apparent that the centermost cans are restrained against movement by the flaps 62. Thus, in effect, the can carrier 60 is reinforced in the vicinity of the center openings 34.

Reference is now made to FIGURES 9 through 12, inclusive, and to FIGURE 9 in particular, wherein there is illustrated another form of can carrier, generally referred to by the numeral 80. The can carrier 80 is very similar to the can carriers 15 and 60*, but differs therefrom only in the means for reinforcing the same. The can carrier 89 is also intended for holding six cans C having chimes or seams S at the opposite ends thereof. The can carrier 80 is formed from a blank which is generally referred to by the numeral 81.

The basic construction of the blank 81 is the same as that of the

blanks

16 and 61. Accordingly, only the differences between the blank 16 and blank 81 will be described in detail, and like parts of the two blanks will be provided with like numerals.

A noticeable difference between the blanks 16 and 8 1 is that the blank 81 is provided with a pair of extension strips 82 which extend along the opposite sides thereof and which overlap small portions of the

bottom forming panels

18 and 20 and extend alongside the ends of the top wall 29 and the

side walls

30 and 31. These strips 52 are connected to the main portion of the blank 81 along elongated fold lines 83. It is to be noted that the fold lines 17, 19, 27 and 28 extend to the outer edges of the blank 81, that is, these fold lines extend across the strips 82. In the forming of the carrier from the blank 81, the strips 82 are folded into overlying relation with the inner surface of the blank 81 and are adhesively secured thereto in a known manner.

The strips '82 form reinforcing for the can carrier 80 in a manner to be described in detail hereinafter. The can carrier 80 also has other reinforcing which is different from the reinforcing of the

can carriers

15 and 66.

Each of the

bottom forming panels

18 and 20 is provided with a single flap, generally referred to by the numeral 8 4, and the top panel 29 is provided with a pair of the flaps 84. Each flap 84 is aligned with a central one of the openings 34 in the final can carrier 80. Each flap 8 4 is defined by a fold line 85 and a out line 86 which are in parallel relation and are parallel to the fold lines 17, 19, 27 and 28, with the fold line 85 being closest to these fold lines. At each end of each fold line 85 is a concave cut 87, and a similar concave cut 88 is formed at each end of the cut line 86. The

concave cuts

87 and 88 adjacent each other have their adjacent ends connected together by a straight cut 89.

Each flap 8 4 is divided into a pair of fia-p portions 9!) and 91 by a generally centrally located fold line 92 which extends the full length thereof. The fold line 92 is interrupted by a C-shaped cut 93 which is aligned with and opposes a respective one of the C-shaped cuts 32.

In the folding of the blank 81 to form the carton 80, each flap 84 is folded along its fold line 92 so that the flap portion thereof either underlies the top wall 29 or overlies the bottom wall 21 formed from the bottom

wall forming panels

18 and 20. At the same time, the flap portion 91 of each flap 84 is disposed in opposed relation to a respective one of the

side walls

30, 31. At this time, the fold line 92 of the flap 84 becomes aligned with a respective one of the fold lines 17, 19, 27 and 28. Also, in the folding of each flap -84, due to the provision of the C-shaped cut 93, and opening 94 is'formed in the flap portion 91 in alignment with a respective one of the central openings 34 (see FIGURE 11). In the -formation of the opening 94, a projection 95 on the flap portion 90 is formed in alignment with a respective one of the projections 35. Thus, the flaps 84 serve to directly reinforce the can carrier 80 along the centermost ones of the openings 34 formed in the side walls thereof.

In the forming of the flap 84, the concave cuts 87 define curved edges 96 at opposite ends of the flap portion 90. The positions and curvature of the curved edges 96 correspond to the positions and curvatures of the seams S of the endmost ones of the can-s C, as is best shown in FIGURE 10. Thus, each flap 84 serves to prevent the corresponding ends of the corresponding endmost ones of the cans from moving inwardly towards the center of the can carrier 80. In a like manner, the inner edges of the folded strips 82 serve as abutments for the seams of the outermost ones of the cans C. Thus the strips 82 and the flaps 84combine, to prevent relative shifting of the outermost cans C with respect to the can carrier 80 and in this manner serve to reinforce the can carrier 86 to prevent tearing along the fold lines 17, 19, 27 and 23 at the ends of the outermost ones of the openings 34.

The formation of the various reinforcements of the several forms of can carriers does not attract from the appearance of the can carriers since the materials primarily required for the reinforcing flaps are formed from the tops and bottoms of the can carriers. Further, the formation of the flaps does not remove critical material from the top and bottom walls of these can carriers and 7 therefore does not weaken these portions of the can oarriers.

'The specific examples of can c-arriens illustrated and described have can seam engaging .projections aligned With-the side wall openings. However, in other similar forms of can carriers these projections are not provided. When can carriers of this type are modified in accordance with the present invent-ion, the reinforcing flaps will normally correspond to the construction of the can carrier and will not be provided with the projections illustrated and described herein.

From the foregoing, it will be seen that novel and advantageous provision has been made for carrying out the desired end.- However; attention is again directed to the fact that variations maybe made in the example apparatus disclosed herein without departing from the spirit and scope of the invention, claims.
