signor to National Folding Box Company, Ine., New Haven, Conn., a corporation of Connecticut Application December 24, 1949, Serial No. 134,887

This invention relates to improvements 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 packaged articles.

Carriers of the aforementioned type are popularly referred to as bottle carriers, 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 bottle 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 may be attached to, or detached from. the carrier body.

Carriers equipped with an integral handle generally have the disadvantage of requiring more stock than carriers within second group. Also, the desirable feature of having a handlewhich extends above the tops of the bottles for convvenient carrying and which is depressible below the tops of the bottles to permit stacking of loaded carriers complicates the construction and increases the cost of the carrier.

Carriers with a detachable handle have become popular in recent years because of certain advantages. Firstly, less stock is required for the carrier body and, secondly, the assembly of Wire handles are sturdy and have the advantage of being salvagable for reuse with a new carrier body, after the initial body wears out, or is discarded by the bottler. Another advantage of the wire handle is the ease with which the handle can be made to telescope to move out of the way for the purpose of stacking loaded carriers.

However, the cost of wire handles is so high as to make their use prohibitive for one-tripcarriers, and often uneconomical for carriers which make only a few round trips between the bottler and the consumer. In addition, the cost of each wire handle mounts. in effect, every time it must be detached from a used carrier body and reassembled with a new carrier body. Another factor inuenclng the average cost of the 4 Claims. (Cl. 224-48) wire handle is the fact that a certain percentage of handle equipped carriers are not returned, but are lost.

The present invention provides a carrier falling within the second of the aforementioned groups. The principal feature of the invention is the provision of a strap handle offering the same advantages as the conventional wire handle, but having the additional advantage of costing only fraction of the cost of a wire handle. Strap 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.

The idea of equipping a bottle carrier with a strap handle is basically not novel. Strap handles made from paperboard have previously been proposed for bottle carriers. However, the known strap handles, as far as can be ascertained, were e.constructed in such a form and were attached to the carrier body in such a way,

transverse bottle separating top webs extending from one side wall of the carrier body to the other side wall, or from one side wall to a center partition and thence to the other side wall. The engagement of the strap handle provided by the present invention with the top webs is such that the strap handle engages the webs along the bottom edge of the webs, the handle being folded at the bottom edge and so constructed that unfolding under the load of the body is prevented.

The invention will be specifically explained by reference to a particularly advantageous form of carrier body forming the subject matter of a separate copending application for letters patent of Marshall I. Williamson Serial Number A157,195 led April\21, 1950. The carrier body 3 carrier, and preventing concentration of the load at isolated transfer points to the handle, in distinction from conventional carriers equipped with wire handles which provide a point-to-point type of engagement between handle and body, rather than an engagement of the edge-to-surface type. The improved strap handles provided by this invention are equally useful for carrier bodies in which the transverse webs are of single ply strength as they are for those in which the webs are of double ply strength.

The various features, objects and advantages of the invention will appear more fully fronf` the detailed description which follows accompanied by drawings showing, for the purpose of illustration, preferred embodiments of the invention as applied to an illustrative form of carrier body. The invention also consists in certain new and original features of construction hereinafter set forth and claimed.

In the following description and in the claims various details will be identified by specific names fox` convenience. The names, however, are intended to be as generic in their application as the art will permit. Corresponding reference characters refer to corresponding parts in the several figures of the drawings.

In the drawings accompanying and forming part of this specification, a certain specific disclosure of the invention is made for the purpose of explanation of broader aspects of the invention, but it is understood that the details may be mOdied in various respects without Adeparture from the broad principles of the invention and that the invention may be applied to other structures than the ones shown.

'I'he blank A as shown in Figure 1 may be cut and scored, in multiple, from large rolls or sheets of foldable sheet material such as paperboard, on automatic cutting and scoring machines. The several constituent parts of the blank are set apart by fold or crease lines. The blank comprises a side wall panel II, a top wall panel I2, a further side wall panel I3, a bottom wall panel I4 and a glue lap I5 hingedly interconnected along fold lines I8, I1, I8, and I8, respectively. Elongated apertures 28 and 2I may be cut in the top panel II for convenient attachment of certain forms of handle, as will later appear.

The top panel I2 and adjoining portions of the side wall panels II and I3 are 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 I8 and l1. These cuts separate the stock into

webs

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

I'he webs are foldable at a plurality of fold lines. These fold lines include diagonal or

obllque fold lines

28, 38, 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, 38, 40, 4I, 42, and 43 extend from similar

short terminal cuts

44, 45 and 46 to the transverse fold line I6 and preferably include between themselves the same angle as the fold lines 29, 38, 3|, 32, 33 and 34. The

webs

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

webs

28 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 web structure is facilitated by a plurality of

crease lines

48, 48', 58, 50', 5I, 5I', 52, 52', 53, 53', and 54, 54'. 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 line I6 and I1 as well as 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, 58, and 6I, 62, 63 and 84 extend with their apex from either end of the ridges of the webs. 'I'hese ridges, as will later appear, are formed by the

ridge fold lines

41 and 48 and by the outer edge portions of the outer edges and 66 of the blank A. The triangular panels are bounded by the transverse fold lines I1 and I8, respectively, forming the bases of the triangles, and by

further fold lines

61, 68, 88, 18, 1I, 12 and 13, 14, 15, 18, 11 and 18, forming the sides of the triangles.

The assembly of the carrier body from 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 I6 and the terminal portion of the panel I I is pressed into adhesive engagement with the glue lap I5. 'Ihe resulting tubular structure l A is shown in Figure 2 and is ready for expansion into hollow form. Flat tubular blanks may 'be stored and shipped to the user in nat collapsed condition, requiring a minimum of space and may be set up into' nal form by a relatively simple assembly operation which may be performed at the bottling plant. These operations will now be described.

The tubular blank A is first squared to assume a substantially rectangular shape as shown in Figure 3.

Article receiving cells

19, 88 and 8| are then formed, and the blank is xed in 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 with respect to the bottom panel |4. Simultaneously the

ridges

65, 41, 48 and 66 are raised and the

triangular panels

51, 58, 59, 60 and 8|, 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 final vertical position which they then automatically maintain due to a 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 |1 in Figures 4 and 5 respectively, and the aforementioned supplemental pressure exerted against these edges causes the web assemblies to snap into the position shown in Figure 5.

The carrier body thus formed is extremely rigid and resistant to deformation due to the truss-like construction of the webs dividing the

cells

19, 80 and 8| from one another.

Figures 6 and 'I show the completed carrier body in plan view and in' end view respectively. It is apparent from both figures that the side walls and |3 have a tendency of sloping inwardly at about the height of the Webs, and this a mansard roof, in the triangular panels from whose apexes the

horizontal ridges

65, 41, 48 and 66 extend.

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 body admirably suited for use with a strap handle which will now be described.

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

intermediate portions

83 and 84 and

end portions

85 and 86. The

intermediate portions

83 and 84 are hingedly connected to the central portion 82 along

fold lines

81 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 89 and 9|). The central portion 82 of the strap handle blank may include a plurality of scores 9| to facilitate subsequent flexing of the handle into U-shape; However, the scores 9| 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 rthe grain should preferably run length wise 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 is4 desired to use stock of lower grade 8 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 portion 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 substantially equal to the Width of the

panels

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

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

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

intermedate panel portions

83 and 84 are then folded at their

respective fold lines

81 and 88 about the

webs

26 and 21, respectively, and the end panel portions and 86 are folded at their

fold lines

89 and 80 and inserted between the

webs

26 and 21 and the upwardly extending central portions 82 of the handle. The stiffness of the stock keeps the

end portions

85 and 86 securely clamped against the

webs

26 and 21.

The assembled handle is shown in perspective in Figure 9. The handle is very secure, and comparable in strength andv load carrying capacity to the best conventional wire handles in spite of its far lower cost. For convenience of stacking loaded carriers the handle may be depressed into a position below the tops of bottles in the carrier, the height of the bottles being indicated by a line 9| in Figure 10. Pressure on the top of the handle causes the handle to become deformed substantially into the shape shown in broken lines in Figure v10. This deformation, however, does not cause the handle to become disengaged from the

vtransverse webs

26 and 21.

The end portions of the

handle

8,5 and 86 are maintained in their handle securing position not only by the stiffness of the stock of the handle but also by the pressure of bottles or other articles within the

pockets

19, 88 and 8| bearing against the

handle portions

82, 84 and 83, 85, respectively. The pressure of the bottles makes it obviously impossible to disengage the handle from the carrier body. I'his is a particular safety feature of the handle construction.

As will be shown, the ends of the handle may be secured in other ways. Figures 11, 12 and 13 illustrate a suitable modification of the handle construction and assembly. Primed reference numerals are employed to identify corresponding blank portions.

The handle blank C comprises a central handle panel 82', intermediate panels 83' and 84', and end panels 85' and 86', hingedly connected to one another along fold lines 81', 88', 89' and 88'. The length of the end panels 85' and 86 is preferably less than the length of the intermediate panels 83', and 84', and the intermediate panels, in turn, are shorter than the height of the webs of the carrier body the handle is to engage. This relationship is more particularly apparent from Figures 12 and 13.

Auxiliary fold lines 9| and 92 may be provided within the central hand grip portion to facilitate assembly of the handle with the carrier body. These auxiliary fold lines may be spaced from the fold lines 81' and I8 a distance substantially equal to the height of the

webs

26 and 21, but

the spacing may be greater or less.

The assembly of the handle with the carrier body is evident from Figure 12. The handle blank is first ilxed into substantially U-shape and the ends of the blank are then folded at their respective fold lines l1' and Il to engage the

webs

26 and 21, and the end of the blank 85' and 86' are folded back and inserted into the apertures v20 and 2| to rest between the two plies of the webs. It is apparent that if the engaged webs were only of single ply strength the ends 85' and 86' will rest between the plies of the webs and the upwardly extending central portion of the handle in assembled position. Insertion of the

ends

85 and 86 into the apertures 20 and 2l is facilitated by folding the blank at the auxiliary fold lines 9| and 92. Subsequent upward pull at the centralfportion then causes the handle to assume the position shown in Figure 12, and the handle to straighten out at the auxiliary fold lines.

Figure 12 illustrates an assembly in which the handle passes through the outer cells of the carrier and the ends of thehandle blank extend upwardly within the central cell. It is evident that the handle may also extend with its central portion through the central cell so that its ends fold upwardly within the space of the outermost cells. This arrangement is shown in Figure 13, in which the same handle blank C is used, the carrier body differing only in one detail, namely in the position of the

apertures

20 and 2| 'i which are found in the outer plies of the

webs

26 and 21. p

The invention thus provides a strong and eilicient handle for carriers comparable in strength to the best wire handles heretofore proposed. The 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 'affected by swinging or rocking the loaded carrier about the point at which the handle is gripped by the user.

creases of the handle and not at inter-locks, cut edges, or projections which provides an edge-toedge rather than an edge-to-surface engagement. This is a critical diierence over known carriers which are extremely sensitive to such rocking which tends to disengage lock tabs at the ends of the strap handle from the carrier body. The present design avoids this weakness by critical changes of design without complicating the assembly of the carrier and handle or increasing their cost.
