9 Claims. (Cl. 224-48) handle is the iact that a certain percentage of handle equipped carriers are not returned, but

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. e

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 o f requiring more stock than carriers within second group. Also, the desirable feature of having a handle which extends above the tops of the bottles for convenient 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 the carrier body is generally simpler and less expensive than the assembly of a carrier body with an integral handle. Prominent among carriers with a detachable handle are those in which the handle is formed from a piece of bent wire. Wire handles are sturdy and have the advantage of being salvageable 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-tripcarrlers, 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 influencing the average cost of the wire 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 oering the same advantages as the conventional wire handle, but having the additional advantage of costing only` a. 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 reinformed with fabric or other reinforcing material, if the handle is to support Van unusually great load or is to be used under 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 constructed in such a form and were attached to the carrier body in such a way, as to become detached too easily.

The present invention is based on the recognition that the strength of the board used in a strap handle must be utilized in a most advantageous manner, if the handle is to remain securely attached to the carrier body, not only under ordinary conditions of use, but also under conditions of abuse, to which bottle carriers are frequently subjected. The strap handle provided by the present invention may be attached to any carrier body equipped with a plurality of 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. 'I'he 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 157,195, led April 2l, 1950. The carrier body comprises transverse webs constructed in such a way as to provide truss structures of extraordinary strength capable of distributing the total load evenly over the entire side walls of the 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 irnproved 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 from 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.

Although the characteristic features of the invention which are believed to be novel will be particularly pointed out in the claims appended hereto, the invention itself, its objects and advantages and the manner in which it may be carried out may be better understood from the detailed description in which:

In the following description and in the claims various details will be identified by specific names for 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 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 modified in 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 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 I6, I1, I8, and I9, respectively. Elongated apertures 20 and 2| are cut in the top panel II for attachment of the handle, as will later appear.

The top panel I2 and adjoining portions of the side wall panels I I 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 I6 and I1. These cuts separate the stock into

webs

25, 26, 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 I6 and preferably include between themselves the same angles as the fold lines 29, 3D, 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

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 web structure is facilitated by a plurality

cf crease lines

49, 46', 50, 50', 5I, 5I', 52, 52', 53, 53', 54 and 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 lines 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, 59, 60, and 6I, 62, 63 and 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 of the

outer edges

65 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 fold lines

61, 68, 69, 10, 1I, 12 and 13, 14, 15, 16, 11 and 18, forming the sides of the triangles. p

The assembly of the carrier body from the blank A may proceedY as follows:

Adhesive c is rst applied to the terminal glue lap I5 and the blank is folded about the fold line IB 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 II is pressed into adhesive engagement with the glue lap I5. The resulting tubular structure 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 flat collapsed condition, requiring a minimum of space and may be set up into final 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 rst 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 fixed 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 andy the

triangular panels

51, 58, 59, 68 and 6|, 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 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 respectively, and the aforementioned supplemental pressure -exerted against these edges causes the web assembly to snap into the position shown in Figure 5.

in plan view and in end View, respectively. Itis,-

apparent from both gures that the side walls and I3 have a tendency of sloping inwardly at about the height of the-webs, and this inward slope then continues, in the manner of 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 app'ied 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 strap handle blank B consists of a central hand grip portion 82 and

end portions

83 and 84 foldaby connected to the central portion 82 along

fold lines

85 and 86. The central portion 82 of the blank B may include a plurality of scores 81 to facilitate s ubsequent ilexing of the handle into U-shape. However, the scores 81 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 should preferably run lengthwise of the handle. Ordinarily it can be used in single ply strength without any reinforcement. However, if thehandle 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 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 ofthe panels 26 and v21 of the Webs, as measured between the fold lines 55 and 56.

The ends of the handle blank B are first reinforced by one or a plurality of metal staples at each end. The number of staples depends on the load to be carried, the width of the handle, and the gauge of the staple employed. In the illustrated form of handle two staples are used at each end. The

staples

88, 89, 98 and 9| extend across the fold lines 85 and 86, respectively, and are preferably struck so that the ends of the staples within the

end panels

83 and 84 are fully bent back upon or into the board, while the other ends of the staples are bent to remain at angle with respect to the board to form a'barb 92 as shown in Figure 10 illustrating one end of the handle B after bending into hook shape at the fold line 86. The portion of the staples within the end panel 84 is preferably shorter than the portion within the panel 82 to produce a tighter grip on the transverse web of the carrier body. The assembly of the strap handle B with the carrier body A" is simple and may be performed as follows:

The blank of the handle B is rst flexed into substantially inverted U-shape, and is then hooked onto the

webs

26 and 21 of the carrier body as shown in Figure 11. The barbs engage the apertures 28 and 2| in the webs `and prevent subsequent disengagement of the handle from the carrier body. The load is sustained by the handle at the fold lines 85 and 86 which provide a surface-to-edge engagement with the lower edges of the

transverse webs

26 and 21. 'I'he load tends to unbend the handle at the fold lines 85 and 86 which is effectively opposed by the stiffness of the

staples

88, 89, 98 and 9| which thus serve the dual purpose of reinforcing the handles at critical points with regard to tear strength, and of addingr to the stiffness of the handle at the same portions.

Te assemb'ed handle is shown in perspective in Figure 1l. 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 convenience of stacking loaded carriers the handle may be depressed into a position'below the tops of bottles in the carrier.

ressure against the top of the handle causes the handle to flatten out slightly at the top. This deformation. however, does not cause the handle to become disengaged from the

transverse Webs

26 and 21 nor the barbs to be Withdrawn from the apertures 28 and 2|. The

end portions

83 and 84 of the handle are maintained in their handle securing position not `only by the staples but also by the pressure of bottles or other articles Within the

pockets

19, 88 and 8| bearing against the

handle end portions

82, 83 and 84, vrespectively. The pressure of the bottles makes it obviously impossible for the handle to become disengaged from the carrier body under load. This is a safety feature of the handle construction.

Strap handles of the type shown in Figure l1 are not limited in their use to carriers in which bottles or other articles of merhcandise are carried in single ille, but are equally useful for carrienbodies of the double row type.

A carrier for six bottles, cans, or similar articlesis shown in Figure 12. The construction of..

the carrier` body |02 is very similar to that of the carrier body A" except for the presence of a center partition 93 which divides the space between the webs |25, |26, |21 and |28 into six pockets. The Webs |26 and |21 are of double ply thickness and include apertures similar to the apertures 2U and 2| in the carrier body A" for engagement by the barbs of the handle 94. The barbs are formed by reinforcing staples in the same manner as shown in Figures 9 and 10, staples being visible at |89 and |9|.

The handle 94is of substantially the same outline as the handle B except for

slits

95 and 96. The

slits

95 and 96 facilitate the assembly of the handle 94 with the carrier body, in that the handle ts easily over the central partition 93.

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 ovel` 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 affectcd by swinging or rocking the loaded carrier about the point at which the handle is gripped by the user, The strength of the handle in this respect arises from the fact that the load is carried at creases of the handle and not at interlocks, cut edges, or projections which provide an edge-to-edge rather than an edge-to-surface engagement. This is a critical difference 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.
