Abstract

A carton and blank (10) for forming a carton for beverage containers which carton includes a series of hinged panels (12, 14, 16, 18, 20, 22) forming a sleeve and end closure panels (34, 36, 38, 40) hinged to at least one associated hinged panel (12, 14, 16, 18, 20, 22) for closing, at least in part, the opposite ends of a sleeve. The said carton includes handle means by which the carton can be carried, said handle means comprising a strap (38) connected to opposed end panels (38, 40) having a user part (74) which is in substantially co-planar relationship with said one hinged panel (18) when in a stored condition. The strap (98) is so connected at its opposite ends to said end closure panels (38, 40) as to provide a surplus of material to enable said user part to be brought into a position of use.

Description

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 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 carton includes a handle by which the carton can be carried, the handle comprising a strap connected to the end closure panels having a user part revealed in one of the hinged panels forming an upper wall of the carton, characterised in that the strap is connected at its opposite ends to end flaps struck from the end closure panels, which end flaps are adapted to flex inwardly so as to provide a surplus of material to enable the user part to be brought into a position of use.

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.

In one class of embodiments, the end flaps may flex inwardly to deform about the shape of an adjacent article contained within the carton.

Preferably there further comprises an intermediate panel to hingedly interconnect the end flap to the upper wall panel. More preferably, the intermediate panel is struck from the upper wall panel.

According to an optional feature of the first aspect of the invention, a portion of said end flap is located between upper portions of adjacent articles at that end of the carton to provide a stabilising spacer therebetween.

Optionally, the end flap abuts the side portion of the article and wherein the intermediate panel extends inwardly of and beyond the abutment point between the end flap and the article side portion thereby to retain the end flap in a flexed condition. The lengths of the end flap and/or intermediate panel may be greater than the distance between the upper wall panel and the article and thereby substantially preventing the user portion from collapsing back into a co-planar relationship with the upper wall panel, once the handle is in a position of use.

According to another optional feature of the first aspect of the invention, the user part may be formed from material which is integral with the upper wall panel.

According to yet another optional feature of the first aspect of the invention the upper wall panel may further comprise a pair of support flaps struck from and hingedly connected to the upper wall panel which flaps are adapted to flex upwardly and outwardly when the strap is placed in face contacting arrangement with the support flaps as the user part is brought into a position of use.

According to a second aspect of the invention there is provided a blank for forming 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, a handle by which the carton can be carried is characterised in that the blank comprises an end flap struck from each of the end closure panels, which end flaps are secured to the handle and are adapted to flex inwardly so that the handle is provided a surplus of material to enable the user part to be brought into a position of use in a set up carton. Preferably there further comprises an intermediate panel to hingedly interconnect the end flap to the upper wall panel. More preferably the intermediate panel is struck from the upper wall panel.

According to an optional feature of the second aspect of the invention, the lengths of the end flap and/or intermediate panel may be greater than the distance between the upper wall panel and the article and thereby substantially preventing the user portion from collapsing back into a co-planar relationship with the upper wall panel, once the handle is in a position of use. According to another optional feature of the second aspect of the invention the user part is formed from material which is integral with the upper wall panel.

According to a further optional feature of the second aspect of the invention the upper wall panel further comprises a pair of support flaps struck from and hingedly connected to the upper wall panel which flaps are adapted to flex upwardly and outwardly when the strap is placed in face contacting arrangement with the support flaps as the user part is brought into a position of use.

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 comer 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 arc 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.

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 preferably, 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.
