Description

BEVERAGE CARTON WITH STRAP TYPE CARRYING HANDLE

This invention relates to a carton which is particularly but not only suitable for accommodating beverage containers such as cans and which incorporates a "strap-type'^'' carrying handle which is automatically set up into a position of use as the carton is being closed after having been loaded.

Beverage cartons which include carrying handles and indeed, strap type carrying

handles are known. For example. US 4,166,570 (Lazerand et al) discloses a packaging

carton for beverage cans with a strap type handle. The handle strap has a central user portion exposed to view in a handle access aperture in a top wall of the carton, extends

across the top wall and has opposite ends which terminate in respective ones of a pair of end closure flaps which are hinged to the top wall. The handle strap is reinforced by a separate strip of reinforcing material, for example, a fibrous tape.

WO 97/07031 (Riverwood International Corporation) discloses a packaging

carton for beverage cans having a handle strap secured at each end thereof to an outer

face of an end panel of the carton between a pair of cuts which extend across the hinge

between the top panel and the respective end panel. As the carton is lifted via the

handle, the provision of a fold line extending between the pairs of cuts on the top panel

allows the portions bounded by the cut lines to deflect inwardly.

The present invention has sought to overcome or at least mitigate the problems of the prior art. One aspect of the invention provides a carton for beverage containers which

carton includes a series of hinged panels forming a sleeve and end closure panels

hinged to at least one associated hinged panel for closing, at least in part, the opposite ends of a sleeve, wherein the said carton includes handle means by which the carton can

be carried, said handle means comprising a strap connected to opposed end panels having a user part which is in substantially co-planar relationship with said one hinged

panel when in a stored condition, the strap being so connected at its opposite ends to said end closure panels as to provide a surplus of material to enable said user part to be

brought into a position of use wherein ends of the strap remote from the user portion are attached to inwardly displaced parts of the end closure panels spaced from said one hinged panel and in that intermediate parts between the user portion and said ends which are unattached to said one hinged panel are free to provide said surplus of

material.

An advantage of the first aspect of the invention is that the structural integrity of

the outer panels of the carton for example the top and end panels is maintained whilst

providing additional stability from the handle structure.

According to another optional feature of this aspect of the invention a portion of

said inwardly displaced parts is positioned to be located between upper portions of

adjacent articles at that end of the carton to provide a stabilizing spacer therebetween. A second aspect of the invention provides a carton for beverage containers

which carton includes a series of hinged panels forming a sleeve and end closure panels hinged to at least one associated hinged panel for closing, at least in part, the opposite ends of a sleeve, wherein the said carton includes handle means by which the carton can be carried, said handle means comprising a strap connected to opposed end panels

having a user part which is in substantially co-planar relationship with said one hinged

panel when in a stored condition, the strap being so connected at its opposite ends to

said end closure panels as to provide a surplus of material wherein ends of the strap remote from the user portion are attached to inwardly displaced parts of the end closure

panels and intermediate parts between the user portion and said ends which are unattached to said one hinged panel are free to provide said surplus of material to enable said user part to be brought into a position of use, said inwardly displaced parts each comprising a step, the tread and riser of the step being provided by an end closure

panel

According to an optional feature of the second aspect of the invention, the step

is positioned to be located between upper portions of adjacent articles at that end of the

carton to provide a stabilizing spacer therebetween.

According to another optional feature of the second aspect of the invention the

panels. Preferably, the tread may abut a side portion of the article and wherein the riser of said step may extend inwardly of and beyond the abutment point between the tread and article side portion thereby to retain the step in a set up condition.

According to an optional feature of the second aspect of the invention the strap

may abut a side portion of the article, the strap being so constructed and arranged to improve the stability of the handle means.

According to a further optional feature of the second aspect of the invention the user part of the handle strap may be connected to a portion of a side wall of the carton.

According to a yet further optional feature of the second aspect of the invention the user part may be formed from material which is integral with the side wall.

According to a still further optional feature of the second aspect of the invention

the step may be automatically put into its operative position when the gusset panel is

folded into its end retaining position.

According to a yet further optional feature of the second aspect of the invention

the step may include a fold line intermediate the fold lines by which it is hinged to the

side panel and to the gusset panel, the step folding in a toggle action along the fold lines

when the gusset panel is folded into its end retaining position. A third aspect of the invention provides a carton for beverage containers which carton includes a series of hinged panels forming a sleeve and end closure panels

hinged to at least one associated hinged panel for closing, at least in part, the opposite

ends of a sleeve, wherein the said carton includes handle means by which the carton can

brought into a position of use.

According to an optional feature of the third aspect of the invention, the ends of the strap remote from the user portion may be attached to inwardly displaced parts of the end panels and intermediate parts between the user portion and the ends which are unattached to said one hinged panel and free to provide said surplus of material.

Preferably, the inwardly displaced parts may each comprise a step, the tread of which is

provided by an end panel and the riser of which is provided by the one hinged panel and

wherein the step is positioned to be located between upper portions of adjacent articles

at that end of the carton to provide a stabilizing spacer therebetween.

According to an optional feature of the third aspect of the invention, the user

portion of the handle strap may be connected to a portion of a top wall of the carton.

Preferably, the central user portion may be formed from material which is integral with said top wall. More preferably, the stabilizing step may be automatically put into its operative

position when the end panel retention means is folded into its end retaining position.

According to another optional feature of the third aspect of the invention, the

stabilizing step may include a fold line intermediate the fold lines by which it is hinged to the top panel and to the end closure panel, the stabilizing flap folding in a toggle action along the fold lines when the end closure panel is folded into its end retaining

position.

A fourth aspect of the invention provides a blank for forming a carton, which

blank comprises a series of hinged panels for forming a sleeve and end closure panels hinged to at least one associated hinged panel, wherein the blank includes handle means comprising a strap connected to opposed end panels having a user part which is in substantially co-planar relationship with one of the hinged panels, the strap being connected at its opposite ends to the end closure panels wherein ends of the strap

remote from the user portion are attached to inwardly displaceable parts of the end closure panels spaced from the one hinged panel and in that intermediate parts between

the user portion and the ends which are unattached to the one hinged panel are free to

provide the surplus of material when the carton is in use.

A fifth aspect of the invention provides a blank for forming a carton, which

blank comprises a series of hinged panels for forming a sleeve and end closure panels

hinged to at least one associated hinged panel, wherein the blank includes handle means

comprising a strap connected to opposed end panels having a user part which is in substantially co-planar relationship with the one hinged panel, the strap being so

connected at its opposite ends to the end closure panels as to provide a surplus of

FIGURE 14 is a cross sectional view of a portion of the carton and an article

showing the arrangement of handle flaps in another class of embodiments.

Referring to the drawings, and in particular Figures 1 , 2, 6, 7, 10 and 1 1 thereof, an article carrier is formed from a unitary blank 10, 210, 310 made from paper board or

other suitable foldable sheet material, which can be adapted to accommodate the variety

of articles, for example twelve bottles arranged in three rows of four bottles each. It is

envisaged the carrier can be adapted to accommodate a different number of bottles according to user requirements.

Turning to the carton blank 10 illustrated in Figure 1 , this blank includes a first

base panel 12, lower side panel 14, upper side panel 16, top panel 18, second upper

panel 20, second lower side panel 22, hingedly connected one to the next in a

longitudinal plane along fold lines 24, 26, 28, 30 and 32 respectively.

The blank further comprises an end closure structure 34, 36 including a pair of

opposed upper ends closure panels (or "adpanels")38, 40 hingedly connected to the top

panel along interrupted fold lines 42 and 44 respectively, positioned along the end

edges of the top panel 18 and a pair of lower end closure panels 39, 41 hingedly

connected to base panel 12 along fold lines 43, 45 respectively. The end closure structure 34 includes gusset panels 46 and 48 connected

together by panel portion 50. Gusset panels 46, 48 extend outwardly from lower and

upper side panels 22, 20 respectively and are connected thereto by fold lines 52, 54. A further overlapping panel 56 is connected to end panel 38 by a lateral fold line and to

gusset panel 46 along fold line 58. The gusset panels 46, 48 and overlapping panel 56 are adapted to form a corner structure as is well known in the art.

Likewise, the opposing corner of the end closure structure 34 also includes

gusset panels 60 and 62 connected together by panel portion 64. Gusset panels 60, 62 extend outwardly from lower and upper side panels 14, 16 respectively and are connected thereto by fold lines 66, 68. A further overlapping panel 70 is connected to end panel 38 by lateral fold line 28 and to gusset panel along fold line 72.

The construction along the opposing side of the top panel and bottom comprises

an end closure structure 36 which is similar and therefore like parts at one end of the

top panel are designated by reference numerals to like parts of the opposite end with the

addition of suffix 'a' and are not described in any greater detail.

The top panel 18 can further comprise a central user portion 74, frangibly

connected to the top panel 18. In this embodiment, the central user portion 74 is

substantially rectangular in shape and comprises a pair of support panels 76, 78

extending into a central user aperture 79 and connected to the side edges of central user

portion along fold lines 80, 82 respectively. Additionally, a handle strap 98, shown in

the Figure 2 can be applied to the inner surface of the blank 10, preferably being secured to the central user portion 74 and the opposed end closure panels 38. 40 by glue at glue points G or by other means known in the art. It is further preferred that the

handle strap is formed from paper board, laminated paper board, fibrous tape or other suitable plastics material.

In one class of embodiments, a stabilizing (or bottle neck spacer) flap 84 shown

in Figure 1 is struck from the blank in the end closure panel 38 so that the flap 84 is hinged to that panel, but otherwise cut out from the blank. Likewise, a second flap 88

is struck from the other end closure panel 40 and is hingedly connected thereto.

The second embodiment shown in Figure 6 and 7 corresponds substantially to

the first embodiment and therefore like parts are designated by reference numerals which are prefixed with the numeral "2". Only those parts of the second embodiment which differ from the first embodiment are hereinafter described. Thus, a stabilizing

(or bottle neck spacer) flap 284 shown in Figure 6 is struck from the blank in the end

closure panel 238 so that the flap 284 is hinged to that panel and to the top panel about

fold line 286, but otherwise cut out from the blank. Flap 284, preferably comprises a

tread panel 285 and a riser panel 287, connected together along fold line 289, which

panels are adapted during carton construction to define a step (or keel element).

The top panel 218 can further comprise a central user portion 274, frangibly

connected to the top panel 218. In this embodiment, the central user portion 274 is

substantially rectangular in shape and comprises a pair of support panels 276, 278

extending into a central user aperture 279 and connected to the side edges of central user portion along fold lines 280, 282 respectively. Additionally, a handle strap 2^C.8, shown in Figure 7 can be applied to the inner surface of the blank 210. being secured to

the central user portion 274 and the opposed end closure panels 238, 240 by glue at glue points G or by other means known in the art. Preferably, the handle strap 29 θ is also glued, or otherwise secured, to the tread panels 285, 287 of each step as shown in Figure 7. It is further preferred that the handle strap is formed from paper board,

laminated paper board, fibrous tape or other suitable plastics material.

The third embodiment shown in Figures 10 to 13 corresponds substantially to

the first and second embodiments in many respects and therefore, where possible, like

parts are designated by numerals which are prefixed with the numeral "3". Turning to the carton blank 310 illustrated in Figure 10, this blank includes a base panel 312, lower side panel 314, upper side panel 316, top panel 318, second upper panel 320, second

lower side panel 322, hingedly connected one to the next in a longitudinal plane along fold lines 321, 326, 328, 330 and 332 respectively.

The blank further comprises one or more end closure structures 334, 336 including a pair of opposed upper ends closure panels (or "adpanels") 338, 340

hingedly connected to the top panel along fold lines 342 and 344 respectively,

positioned along the opposing end edges of top panel 318. In this embodiment, the end

closure structures 334, 336 also include a pair of lower end closure panels 339, 341

hingedly connected to base panel 312 by fold lines 343, 345 respectively formed along

the opposed longitudinal edges of base panel 312. End closure structure 334 may also include gusset panels 346 and 348

connected together by panel portion 350. Gusset panels 346, 348 extend outwardly

from lower and upper side panels 322, 320 respectively and are connected thereto by

fold lines 352, 354. A further overlapping panel 356 is connected to upper end panel 338 by a lateral fold line and to gusset panel 346 along fold line 358. The gusset panels

346, 348 and overlapping panel 356 are adapted to form a corner structure, as is well

known in the art.

Likewise, the opposing corner of the end closure structure 334 also includes

gusset panels 360 and 362 connected together by panel portion 364. Gusset panels 360,

362 extend outwardly from lower and upper side panels 314, 316 and are connected thereto by fold lines 366, 368. A further overlapping panel 370 is connected to upper end panel 338 by a lateral fold line and to gusset panel along fold line 372.

The construction along the opposing side of the top panel and bottom, which

includes end closure structure 336, is similar and therefore, like parts at one end of the

top panel are designated by reference numerals to like parts of the opposite end, but

with the addition of suffix 'a' and are not therefore described in any greater detail.

One or more handle flaps 384, 384a, shown in Figure 10, is struck from the

blank, which in this embodiment is formed from the gusset panel 360 and/or side panel

314, so that the flap 384 is hinged to that panel 360 and preferably to the side panel 314

about fold line 386, but is otherwise cut out from the blank by opposed cut lines 392,

394 in substantially parallel spaced arrangement. Flap 384, preferably comprises a tread panel 387 and a riser panel 389. connected together along a fold line, which panels are adapted during carton construction to define a step (or keel element). In this embodiment the tread panel 387 is separated from the gusset panel 360 by panel 385 and hingedly connected thereto along fold line 390 described in more detail below.

Preferably, the handle flap 384 is separated from gusset panel 360 and lower

side panel 314 by apertures 393, 395 to make it easier for the flaps to be folded out of alignment with the gusset panel 360 and lower side panel 314.

The side panel 314 may further comprise a user portion 374, frangibly

connected to the side panel 314 along frangible lines 375 and positioned in a central region of the side panel. In this embodiment, the user portion 374 is substantially rectangular in shape and comprises a pair of support panels 376, 378 extending into a central user aperture 379 and connected to the side edges of central user portion along fold lines 380, 382 respectively.

Additionally, a handle strap 398, shown in the Figure 11 can be applied to the

inner surface of the blank 310, preferably being secured to the user portion 374 and the

opposed gussett panels 338, 340 by glue 416, 414 or other means known in the art.

Preferably, the handle strap 398 is also glued to the tread panels 385, 387 of each step.

It is further preferred that the handle strap is formed from paper board, laminated paper

board, fibrous tape or other suitable plastics material. Along the opposed lateral edges of user portion 374, there may further comprise a handle tab 400 struck from lower side panel 314 by lateral cut lines 402, 404. In use

the handle tabs guide the handle strap when displaced outwardly.

Cut lines 406, 406a struck from lower end panels 339 and 341 may be included to co-operate with handle flaps 384, 384a.

In another class of embodiments, the handle structure may comprise one or more handle flaps (not shown) struck from the gusset panel 360 or other suitable panel

so that the flap is hinged to that panel along one edge but is otherwise cut out from the blank in a manner similar to the first embodiment. Likewise a second flap could be

struck from the opposing gusset panel 360a or other suitable panels and be hingedly connected thereto. A handle strap would be secured to the opposing handle flaps and preferably a user portion, but would otherwise be unconnected to the blank.

Turning to the construction of the carton, illustrated in Figures 3, 4, 5, 8, 9 and

12, 13 the blank 10, 210, 310 requires a series of sequential folding and/or gluing

operations which can be performed in a straight line machine so that the carton is not

required to be rotated or inverted to complete its construction. The folding process is

not limited to that described below and can be altered according to particular manufacturing requirements.

The carton is usually supplied to a bottler in a flat collapsed tubular condition:

the base panel 12, 212, 312 already connected to lower side panel 22, 222, 322 by securing the glue flap 94, 294, 394 to the lower side panel 22, 222, 322 by glue or other

suitable means. In order to set up the carton, the sides and top and base panels are separated to form a tubular structure, as is well known.

Thereafter, articles are introduced to the part constructed carton and the end closure structure is formed. In the first embodiment, the end closure panels 38 and 48

are folded downwardly at each end of the sleeve formed by the wrap around folding

action. Gusset panels 46, 48, 50 and 60, 62, 70 are folded inwardly about fold lines 52, 54 and 66, 68 respectively whereby gusset panels 46, 48, 60, 62 come into face to face relationship with side panels 22, 20 and 14, 16 respectively. Panels 56, 70 come into

face to face contact with their respective adjacent gusset panels 46, 62.

Optionally, the faces of gusset flaps 46, 60 in contact with upper side panels 16,

20 respectively may be secured together by means known in the art to hold the end

closure panels in place. Thereafter, lower end closure panels are folded about fold lines

and into abutment with upper end closure panels 38, 40 and are secured together by

glue or other means known in the art. The end structures of the second and third

embodiments are formed in a substantially identical manner and construction thereof is

not therefore described in any greater detail.

Thus, the cartons of the first, second and third embodiments are in a set up and

loaded condition as shown in Figures 3, 8 and 12 respectively. The first embodiment

advantageously allows the top and the end of the carton to remain intact thereby improving the structural integrity of the carton during handling and storage, caused in part because the fold lines connecting the top and upper side panels are continuous.

The embodiment shown in Figure 12 allows the top of the carton to remain intact and thereby also improves the structural integrity of the carton during handling and storage, again caused in part because the fold lines connecting the top and upper

side panels are continuous.

In order to form the handle in the first embodiment illustrated in Figures 4 and

5, the central user portion 74 can be detached from the top panel 18 whereby at least a portion of the handle strap stands proud of the top panel, shown in Figure 4. It will be

seen from Figure 5 that the strap is so connected at the opposite ends of the end closure panels as to provide a surplus of material to enable the central user portion 74 to be

brought into a position of use. The support panels 76, 78 are folded under the handle

strap, such that the central user portion 74 is wrapped around the strap, the central user

portion 74 provides a cushion for the strap, shown in Figure 4. Further, the central user portion 74 is designed for ease of use.

In the second embodiment, the handle is formed by folding each of the

stabilising (or bottle neck spacer) flaps 284 and 284a.. Flaps 284 and 284a are formed

with cut lines 292, 294 preferably divergent from fold line 289 and cut lines 293, 295

intermediate and substantially perpendicular to fold lines 286 and 289 about which

flaps can fold in a toggle action to define a step at each end of the top panel 18. This

action can occur automatically upon folding the end closure panels which brings the flaps into their operative position in which the flaps are displaced out of the plane of the

top panel inwardly of the carton, as shown in Figure 9. Optionally, cut lines 292, 294;

293, 295 are shaped to define a shaped edge adapted to cooperate with a neck portion of

an article. Once displaced the, or each, stabilizing flap 284 is disposed between neck portions of adjacent rows of articles within the package to assist in maintaining the articles in their correct upright positions within the package, particularly to prevent the

articles topping inwardly whereas the end closure panels prevent the bottles toppling end wise of the package.

In order to form the handle of the third embodiment as illustrated in Figure 13

the user portion 374 can be detached from the side panel 314 and, the handle is then formed automatically by folding each of the handle flaps 384. More particularly, a keel

structure is formed by folding panels 385, 387 and 389 inwardly of gusset panel 360 such that tread panel 385, 387 and riser panel 389 are substantially perpendicular or

more preferably in an acute angular relationship. Thus, the flaps 384 can fold in a

toggle action to define a step at each end of the lower side panel 314. This action can

occur automatically when a user pulls on the handle strap which brings the flaps into

their operative position by which the flaps are displaced out of the plane of the top

panel inwardly of the carton, as shown in Figure 13. Once displaced, the or each panel

385 abuts the product. Advantageously, the strap 398 is held between the product and

carton which permits additional resistance.

In other embodiments, the keel structures 418, 420 are so formed to allow the

tread panel 385, 387 to abut the article as shown in Figure 14. Preferably, once the step is formed and the tread and riser panels are folded into perpendicular (or angular)

relationship, they are so constructed to be held in place. More preferabK'. when the user forms the step, it is "overcentre" of the notional plane X-X between the tangential point

of contact between the article and strap and the fold line between the riser and side

panel and therefore is prevented from collapsing back to a co-planar relationship with the side and gusset panels. In some embodiments, this is achieved because the tread

panel 387 and/or riser panel 389 is greater in length than the distance "d"' between the side panel 314 and the article A.

One advantage of this arrangement of handle structure is that the handle

structure is more rigid and once the user part has been separated from the side panel it continues to protrude beyond the side panel whilst providing a handle strap that can be shaped to the contour of the outermost article A carried by the carton.

When the carrier of any of the embodiments is in use there is a tendency for the

handle strap to draw the end closure structures 34, 36, 234, 236, 334, 336 inwardly

thereby to improve the integrity of the carton and providing a self tightening effect.

Furthermore, in those embodiments where the strap and/or tread and riser flaps are

positioned between neck portions of adjacent bottles, the stability of the carton is

improved due to support from the articles.

Advantageously, the preferred embodiments of the present invention illustrate a

carton having a strap handle type, the strap being reinforced by a separate strap formed

from material at one end of the blank from which the carton is formed. The handle strap is connected to a handle and has a user portion exposed to view in a handle access aperture but which is otherwise disposed internally of the carton.

The carton is set up as an open-ended sleeve for loading and is then end-loaded whereafter the carton is completed by closure of the end closure panel. The end closure panel closing has an effect on the disposition of the handle strap. As the top end

closure panels are folded into their closing positions the handle strap becomes slack

into a position ready for use. When the carton is lifted by the central user part of the handle strap, the strap bows upwardly and protrudes through the handle access aperture proud of the top/side wall. The load is transmitted from the handle strap to the end wall

of the carton at each of the opposite ends of the handle access aperture and is

distributed through the end wall.

The present invention and its preferred embodiment relate to an article carrier

which is shaped to provide satisfactory strength to hold articles securely but with a

degree of flexibility so that load transfer to the handle is absorbed by the carrier. The

shape of the blank minimises the amount of paper board required and the carrier can be

applied to an array of articles by hand or automatic machinery. It is anticipated that the

invention can be applied to a variety of carrier and is not limited to the wrap around

type. For example the top panel 18, side panels 14, 16, 20, 22 and end closure structure

34, 36 of the aforementioned carton can be applied to other carton types for example

top gripping cartons, without departing from the scope of the invention.
