l This invention relates to improvement in carriers made from foldable sheet material, such as paperboard, for packaging a plurality of bottles, cans, jars, or similar articles as a unit which may easily be stacked by the dealer, carried home by the consumer and which, in addition, provides protection for" the packagedr articles.

Carriers of the aforementioned type are popularly referred to as bottle carrier, and this term will be used hereinafter for convenience, although it is plain that a carrier for bottles is equally useful for the packaging of cans, jars, and similar articles of merchandise.

The commonly known carriers may be divided into two groups, a first group comprising those carriers in which the handle forms an integral, or non-detachable, part of the carrier body, and a second group comprising those carriers in which the handle constitutes a separate element which maybe attached to, or detached from, the carrier body.

A Carriers equipped with an integral handle generally have the disadvantage of requiring'v more stock than carriers within the second group. AAlso, vthe desirable feature of having a handle 3 Claims. (Cl. 224--48) which extends above the tops of the bottles or other articles for lconvenient carrying and which is depressible below the tops of the bottles or articles topermit stacking of loaded carriers complicates the construction and increases the cost of the carrier.

Carriers with a detachable handle'have`become vpopular in recent years because of `certain advantages. Firstly, less stock is required for the carrier body and, secondly, the assembly of the carrier body is generally simplerand less expensive than the assembly of a carrier body with an integral handle. Prominent among carriers with .a detachablel handle are those in which the hanvdle is formed from a piece of bent wire.

l* Wire .handles are sturdy and have the advantage of being salvagable for reuse with a new carrier body,

Yafter the initial'carrier body wears out, or is dis.-

carded by the bottler. Another advantage of the to make their use prohibitive for one-trip-car- =riers,`and.often-uneconomical for carriers which make only a few-round trips between the bottler and the consumer. In addition, the cost ofr each wire handle mounts, in effect, every time it must beAdetachedfrom a used carrier body and reas- .sembled witha new carrier body. Another factor Y influencing the average cost of the wire handle is the fact that a certain percentage of 'handle equipped carriers are not returned, but are losti The present, invention provides an improvement falling within the second of the aforementioned groups. The principalfeature of the inlvention is the provision of a strap handleoiiering the same advantages as the conventional wire handle, but havingv the additional advantage of costing' only `fraction Vof the cost of Eawire handle. rStrap-handles incorporating the present invention are conveniently made from paperboard, `The board may; but need not necessarily, be reinforced 'with fabric or other reinforcing material, if the handle is to support an unusually great load or is to be used underv unusually unfavorable conditions. "-1

The idea of equipping a bottle carrier ywith a strap handle is basically not novel. Strap handies made from paperboard have previouslyrbeen proposed for bottle carriers. However, the known strap handles, as far as can be ascertained,'were constructed in such a `form and were attached to the carrier body in such a Way, as to become detched tooeasily. l

The present invention is Ybased on rthe recognition that the `-strength of the board' used in a strap handle must be utilized in af most advanftageousumanner, if the handle is to remairi-securely attached to the carrier body, not only lnder ordinary conditions of use, Vbutalso under conditions of abuse, to which bottle carriers `are Vfre'- quently subjected. The strap handle provided l by the present invention is particularly suited-for use with a carrier body equipped with a plurality Vof transverse bottle separating top webs extending from one side wallfof theY carrier body'to the other side Wall, or from one side wall to a center partition and thence to the other iside wall. The engagement of the strap handle provided by the present invention with the top fwebs 'is suchthat the strap handleengages 'the 'Webs along the bottom edge of the webs, the handle being folded at the bottom edge andl so con- "structed that unfolding under the load of the body is prevented. Likewise accidental disengagement of the handle Yfrom'the carrier -body `when lnot Vloaded is prevented.

In the following description and in the claims yarious details will be identied by specific Ynames for conveniences. The names, however, are intended'to be as generic in their application as the vart will permit. Corresponding reference characnters refer to corresponding parts in the several figures of the drawings.

In the drawings accompanying and forming part of this specification certains'pecic disclosure of the invention is made for the purpose of explanation of broader aspects of the invention, butit is understood that the details may be modi- Q-iiedin various respects without departure from :the broad principles of the invention and that the invention may be applied to other structures than the ones shown.

The blank A is shown in Figure 1 and may be cut'an'd scored, 'in multiple, from large'rolls orl sheets of 'foldable sheet material such as paperboard, on autdmatic cutting and scoring 'mafch'ines. The several constituent partsv of the Zfblanka're set apart by fold' or' crease lines. The

blankbomprises aside wall panel II.' a top :wall x panel I2, a further side wall panel I3, a bottom Wall panel I4 and a glue lap I5 hingedly interconnected along fold lines IB, I1, I8, and I9, respectively. Slits or apertures 20 and 2l are cut in the top panel II for convenient attachment of the handle, as will later appear.

The top panel I2 and adjoining portions of the side wall panels II and I3 lare cut and scored to provide a cellular web structure forming individual compartments for bottles or other forms of merchandise.

Cuts

22, 23 and 24 extend at right angles to the fold lines I6 and I1. These cuts separate the stock into

webs

25, 2B, 21 and 28 which after appropriate folding form article receiving cells as will later appear.

The webs are foldable at a plurality of fold lines. These fold lines include diagonal or

oblique fold lines

29, 30, 3|, 32, 33 and 34 extending from

short terminal cuts

35, 36 and 31 to the transverse fold line I1 at an angle. Similar

diagonal fold lines

38, 39, 40, 4I, 42 and `43 extend from similar short terminal cuts 44, 45, and 46 to the transverse fold line I5 and preferably 'include between themselves the same angle as the fold lines 23, 30, 3|, 32, 33 and 34. The

webs

25 and 28 constitute terminal webs since they Alie at the outer edges of the blank. The

webs

26, and 21 constitute intermediate webs. These intermediate webs comprise ridge fold lines'41 and 48 to provide for double ply thickness of the intermediate webs, as will later appear.

Folding of the webstructure is facilitated by a plurality of crease lines 49, 49', 5I), 50', 5I,`5I, 52, 52', 53, 53 and 54, v54. These crease lines subdivide the several webs into individual 'web portions. It is evident that the angles at which these crease lines intersect, as well as their outline, depends on the width of the panel I2, measured between the fold lines I6 and I1, as well as on the depth or height of the respective webs in the finished carrier body.

Further

transverse fold lines

55 and 56 extend across the blank to facilitate folding of the Webs as will later become apparent.

Triangular panels

51, 58, 59,60, 6I, 62, 63and 64, extend with their apexes from either end of the ridges of the webs. These ridges,` as will later appear, are formed by

the'ridge fold lines

41 and 48 and by the outer edge portions ofthe outer edges and 66 of the blank A. The triangular panels are bounded by the transverse fold lines I1 and I6, respectively, forming the bases of the triangles, and by

further foldlines

61, 68, 69, 10, 1I, 12 and 173, 14, 15, 16, 11 and 18, forming the sides of the triangles.

The assembly of the carrier body vfrom the blank A may proceed as follows:

Adhesive a is first applied to the terminal glue lap I5 and the blank is folded about the fold line I8 to bring the panel I4 face-to-face with the panel I3. Thereafter the blank is folded about the fold line I9 and the terminal portion of the panel II is pressed into vadhesive engagement with the glue lap I5. The resulting tubular structure A is shown in Figure 2 and isreacly for expansion into hollow form. Flat tubular blanks may be stored and shipped tothe user: in flat collapsed condition, requiring a minimum of space and may be set up in expanded form by a relatively simpleassembly operation vwhich may be performed at the bottling plant. These operations-will now be described.

VThe tubular blank A is first squared-to assume "asubstantia-lly rectangular shape as shown'n Figure-3. `Article receiving cells 19, 8D and8 Ifare then formed, and the blank is xedin expanded position by exertion of force in the direction of arrows F against the

several web panels

25, 26, 21 and 28. This force causes the web panels to move towards a vertical position withrespect to the bottom panel I4. Simultaneously the

ridges

65, 41, 48 and B6. are raised and the

triangular panels

51, 58, 59, 68 and.6.l, 62, 63 and 64 assume a slanting position as shown in Figure 4. Further pressure against the web panels and supplementary pressure against the tilting edges I6 and l1 .causes the web panels to assume their nal vertical position which they then automatically maintain due toa peculiar behavior inherent in the illustrated structure which may be compared to the action of the commonly known over-center spring which snaps into one or the other of two extreme positions after being forced past its center position. A center position is encountered in the present assembly between the positions of the edges I6 and I1.. in Figures 4 and 5 respectively, and the aforementioned supplemental pressure exerted against these edges causes the web assembly to snap into the position shown in Figure 5.

The carrier body thus formed is extremely rigid and. resistant to deformation due to the trusslike construction of the webs dividing the cells 19; 80 and 8l from one another.

p Figures 6 and '1 show the completed carrier body in plan view and in end view respectively. It is apparent from both figures that the side walls ll and I3 have Aa tendency of sloping inwardly at about the height of the webs, and this inwardslope then continues, in the manner of a mansard roof, in the triangular panels from whose apexes the

horizontal ridges

65, 41, 48 and lextend. Y A

The resulting carrier body possesses a surprising amount of strength and rigidity to a lifting force applied at the lower edges of the bottle separating webs, particularly to the

webs

26 and 21 which are of double ply thickness. This peculiarity makes the carrier bodyY admirably suited for usewith a strap handle which will now be described. l

Referring to Figure 8 the flat blank B of the strap handle consists of a central hand Igripportion 82,

intermediate portions

83 and 84 and

end portions

85 and 85. The

intermediate portions

83 and 84 are hingedly connected to the central portion 82 along fold lines S1 and 88, and the

end portions

85 and 86 are articulated to the

intermediate portions

83 and 84 in a similar manner along fold lines 88 and 98. The central portion 82 of the strap handle blank may includea plurality of scores 9| to facilitate subsequent flexing of the handle into U-shape. However, the scores 8| are not indispensable and may be omitted.

The blank B is made from paperboard, preferably board having substantial tear strength. Kraft is suitable stock for the handle and the grain should preferably run lengthwise of the handle. Ordinarily it can be used in single ply strength without reinforcement. However, if the handle is to be used under particularly unfavorable conditions, if the load is exceptionally great, or if it is desired to use stock of lower grade for the handle, the blank B may be made of laminated stock particularly stock including a fabric ply.

The shape of the blank B is optional. It may be made of equal width throughout, or, as shown in Figure 8, the central portion may be made progressively narrower for more convenient gripping of the strap by hand. In the latter case the handle blanks may suitably be laid out in a continuous strip of board in such a way that the Wider end portions of two handle blanks lie adjacent the narrow portion of an adjacent handle blank. It is preferable, although not necessary, to make the

intermediate portions

83 and 84 of a width w substantially equal to the width of the

panels

26 and 21 of the webs, ,as measured between the fold lines 55 and 56. l

VThe length L of the

intermediate portions

83 and 84 is less than the length of the

panels

26 and 21, as measured between the fold line 41 and the

edges

22, 23 and, with respect to panel 21, measured between the fold line 48 and the

edges

23 and 24. The length Z of the

end portions

85 and 86 is so dimensioned that in folded-over position indicated in Figure 8 in dotted lines, the terminal edge of the end portions and 86 is at a distance h from the fold lines 81 and 88. This distance h should be equal to, or slightly more than, the distance of the cuts 26 and 2 I from the edges 23. The relative dimensions are also shown in Figure 10 in lwhich the end of the handle is illustrated inserted into the web 21.

,The assembly of the strap handle B with the carrier body A is simple and may be performed as follows: Y

The blank B of the handle is flexed into substantially-inverted U-shape. The

intermediate panel portions

83 and 84 are folded at their respective fold lines B1 and 88, and the

end panel portions

85 and 86 are folded at their

fold lines

89 and 58. Thus folded the ends of the handle are insertedk into the slits 28 and 2l' far enough to cause the terminal edges of the

end portions

85 and 86 to snap past the lower edges of the cuts 2U and'2l, as shown in Figure 10.

The assembled handle is shown in perspective in Figure 9. The handle is very secure, and comparable in strength and load carrying capacity to the best conventional wire handles in spite of its far lower cost. For convenienceof stacking loaded carriers the handle may be depressed into a position below the tops of bottles, cans, jars, or other articles in the carrier. Pressure on the top of the handle deforms the handle slightly. This deformation, however, does not cause the handle to become disengaged from the 'transverse webs- 26' and 21. The

portions

83 and 84 of the handle are maintained in locked position by the end flaps 85 and 86 which engage with their terminal edges the edges' formed in

thewebs

26 and 21 by the cuts 20 and 2l.

Even if,`in depressing the handle as mentioned above, the terminal edges of the

flaps

85 and 86 do not engage the edges of the web cuts 28 and 2 l, the handle still will not disengage from the carrier body since the stiffness of the handle material at the fold line 90 causes the flaps to pass inside-not outside-the cuts in the webs.

The invention thus provides a strong anden-icient handle for carriers comparable in strength to the best wire handles heretofore proposed. 'I'he improved strap handle can be produced at a fraction of the cost of a, wire handle, and rests in the hand of the user more comfortably than a wire handle because of its larger grip surface. It has the advantage over the Wire handle of engaging the carrier blank along the extended bottom edges of the webs rather than at isolated points of engagement as would be the case if a wire handle were used.

The carrier is considerably more reliable than any paperboard carrier with strap handle heretofore proposed in that its strength is not affooted by swinging orrocking the loaded carrier about the po-int at -which the handle is gripped bythe user. The strength of the handle iii this respect arisesffrom the fact that'the load is carried at creases of the handle and not at interlocks, out edges, orprojections-which provide an edge-to-edge rather thanan edgetosur face engagement. `This is a critical difference over known carriers'which are extremely-sensitive to such rocking which tendsto disengage lock tabs at the ends of the strap handle from the carrier body. The presentdesign avoids this Weakness by critical changesoi? design without complicating the assembly of the carrier and handle or increasing their oost.
