Detailed Description of the Preferred Embodiments Referring to the drawings, and in particular Figure 1, there is shown a unitary blank 10 for forming an article carrier made from paperboard or similar foldable sheet material. In other embodiments there may comprise a two-part blank, for example a blank for forming the wraparound carrier and a separate blank for forming the internal article retention structure.
The blank 10 comprises a series of panels hingedly connected one to the next in series to define a top wall, opposed side walls and a base. Preferably, there comprises upper and lower side wall panels. Thus, the blank 10 comprises a plurality of panels for forming a wraparound carton, which in this embodiment comprises a first side wall panel 14, a base panel 16, second side wall panel 18, an upper second side wall panel 20 and top wall panel 22 hingedly 2o connected together in series along fold line 32, 34, 36 and 38 respectively.
In order to secure the first side wall panel 14 to the top panel 22, suitable securing means is provided. In this embodiment, the securing means is provided by a securing flap 12 that is hingedly connected to the lateral edge of side panel 14 along fold line 30.
There further comprises a plurality of panels for forming the article retention structure which are hingedly connected to the top panel 22 along fold line 40. In this embodiment, the article retention structure is provided by a first spacer panel 24, a retention panel 26 and a securing panel 28 hingedly connected together in series along fold lines 42 and 44 respectively. The spacer panel 24 spaces the retention panel 26 from the top panel 22.
There may further comprise one or more display windows which are provided by apertures 46, 48 struck from upper second side wall panel 20 that extend into top panel 22, shown in Figure 1. In use, the display apertures 46, 48 reveal a portion of the cap of the article retained within the carrier.
A brace is provided to prevent the article retention structure from collapsing. In Figure 1, there comprises a brace panel 50 struck from and hingedly connected to retaining panel 26 along fold line 54. Preferably, there further comprises a friction tab 58 struck from the adjacent spacer panel 24 and hingedly connected to bracing panel 50 along fold line 62. In use, the bracing panel 50 is folded out of alignment with retaining panel 26 to reveal an article receiving aperture 90 (Figure 7). A second bracing panel may be provided which, in this embodiment, is designated by a reference numeral 52 and is struck from retaining panel 26 and hingedly connected thereto along fold line 56. Similarly, a friction tab 60 is hingedly connected to bracing panel 52 along fold line 64.
Turning to the second embodiment illustrated in Figure 2, the blank 110 is substantially the same as the first embodiment and like features are designated by the same reference numerals with the prefix "1 ". Therefore only the differences shall be described in any further detail.
2o An end closure structure is provided to prevent the articles from inadvertently being removed, for example, before the product has been sold. The end closure structures are provided by opposing end panels 176a and 176b hingedly connected to opposing sides of side wall panel 118 along fold lines 175a and 175b respectively. Suitable securing means is provided to secure the end closure panels 176 in place, for example a locking tab and aperture arrangement could be used.
The construction of each end closure structure is the same, so like reference numerals have been used in Figure 2 with the addition of letter's 'a' and 'b' respectively.
In this embodiment, glue flaps 178 and 180 are provided to be secured to the adjacent first side wall 3o panel 114 and the base wall 116 respectively. It will be seen from Figure 2 that glue flap 178 is secured to a longitudinal edge of end closure panel 176 along fold line 182 and that glue _7_ flap 180 is secured to a lateral edge of end closure panel 176 along fold line 184, which in this embodiment is an extension of fold line 134.
Turning to the third embodiment illustrated in Figure 3, it is similar to the first embodiment in its overall construction; and it is similar to the second embodiment in that there are provided end closure panels 276. Like features of the first and second embodiments are designated by the same reference numeral with the prefix "2". Therefore, only those differences between the second and third embodiments are described in any further detail.
to In the third embodiment, there further comprises an additional aperture 270 along the opposing part of top panel 220 which is aligned with the corresponding aperture 246.
Aperture 270 is struck from top panel 220 and extends into spacer panel 224.
In use, aperture 270 provides a second display window for the upper portion of the adjacent article A.
Likewise, in those embodiments with two rows of articles, a second aperture 272 struck from 15 top panel 220 and extending spacer panel 224 is provided to be substantially aligned with aperture 248.
There are also corresponding recesses 286, 288 along the free edge of side panel 214. In use, the recesses 286 and 288 are aligned with aperture 270 and 272 respectively to provide a 2o display window.
In one class of embodiments, the friction tab 258 is not co-extensive with bracing panel 250 and terminates short, so that an aperture or notch 266 is provided. In use, the notch 266 functions to allow the tab 258 to protrude through the opening 270 to be engaged with an 25 article. There is a similar notch 268 provided adjacent to bracing tab 260 that functions in the same way.
There may further comprise an aperture 274 struck from one of the side panels and a corresponding recess portion 289 in glue flap 228 to provide an additional display window to 30 reveal part of the side wall of an article A.
_g_ Turning to the fourth embodiment illustrated in Figure 14, it is virtually identical to the third embodiment in its overall construction except for the details of the friction tabs. Like features of the third embodiment are designated by the same reference numeral with the prefix "3".
Therefore, only those differences between the third and fourth embodiments are described in any further detail.
In the fourth embodiment, the friction tab 358, again, is not co-extensive with bracing panel 350 and terminates short. However, an aperture or notch 366 is defined adjacent to the free end edge of the bracing panel 350 remote from fold line 354. In use, the notch 366 functions to to prevent the tab 358 from being exposed to view through opening 370. In other words, the notch 366 is struck from the friction tab 358 to cooperate with the opening 370 to provide a window to reveal the top portion of one of the articles. There is a similar notch 368 provided adjacent to the free end edge of bracing panel 352. The notch 368 functions to prevent friction tab 360 from being exposed to view through opening 372.
Turning to the construction of the carton formed from one of the blanks illustrated in Figures l, 2, 3 or 14, it is envisaged that the carton of the present invention can be formed by a series of sequential folding and gluing operations which can be performed in a straight line machine, so that the carton is not required to be rotated or converted to complete its 2o construction. The folding process is not limited to that described below and can be altered according to particular manufacturing requirements.
Turning now in particular to Figure 4, the blank 10 of the first embodiment is folded in direction X along fold line 40 to form the internal article retention structure. Thus, spacer panel 24 and retaining panel 26 are placed in face-contacting relationship with top panel 22 and upper second side wall panel 20 and are held in place by securing flap 28 to side wall panel 18 by glue G or other suitable securing means known in the art. The carrier is at an intermediate stage construction, shown in Figure 5, whereby it is in flat collapsed condition ready to be supplied to a user, for example a bottler, to be loaded with articles, described below.
In order to construct and load the carrier, the retention structure and brace are formed, whereby panels 20, 22, 24 and 26 forming the article retention structure are folded along fold lines 38, 40, 42 and 44 in direction Y so as to form a tubular structure T as shown in Figure 6.
This folding action reveals friction tabs 58 and 60 that are ready to form the brace.
Thereafter, the brace is formed by folding brace panels 50 and 52 in directions W and V
respectively along fold lines 54 and 56 as shown in Figure 7 to take up a bracing position.
The bracing panels 50, 52 act as braces by their free edges coming into contact with opposed spacer panels 24, 28 or, as the case may be, side walls. Additionally, or alternatively, the bracing tabs may abut the top wall to provide a brace between the top and retention panels 22, 26.
In those embodiments with friction tabs 58 and 60 are folded along fold lines 62 and 64, so as to come into face contacting relationship with spacer panel 24. It is envisaged that in some embodiments the spacer panels are dispensed with, in which case the friction tabs come into face contacting relationship with the side walls.
Turning again to the embodiment shown in Figure 7, the brace panels 50, 52 are held in place by the frictional engagement between the inner face of spacer panel 24 and the tabs 58 and 60 respectively, thereby to maintain the tubular structure in a set-up condition.
Optionally, glue 2o may be applied to friction tabs 58, 60 so that they are secured to spacer panel 24. The tabs 58, 60 may be shaped so as to protrude in part 59, 61 (Figure 9), through apertures 90, 92.
Beneficially, this allows tabs 58, 60 to be secured directly to an outer panel of the carrier, for example, securing tab 12 to provide a structure of improved rigidity.
In order to complete construction of the carton, the panels forming the wraparound carrier are formed, so that the base panel 16 and first side wall panel 14 are folded out of alignment with second side wall panel 18 along fold lines 34 and 32 respectively as shown in Figure 8.
Prior to constructing the wraparound carrier, the articles are applied to the carrier by relative 3o movement between the article A and the tubular structure T, preferably during continuous forward movement. The articles are grouped in a two-by-two array although is anticipated that other groupings or even a single article could be packaged without departing from the scope of the invention.
As shown in Figures 9 and 10 the articles pass through apertures 90 and 92 to be held in place within the tubular structure T. In some embodiments, suitable retention means engage the upper part of the articles) to prevent any movement within the apertures 90, 92. Thereafter, the side and base walls are folded as described above and the first side wall panel 14 is secured to the article retention structure by securing glue flap 12 to spacer panel 24 by glue or other suitable means known in the art. Thus, the carton is in set-up and loaded condition as to shown in Figure 10.
It will be seen that the articles to be packaged, in this embodiment, are flexible foil pouches and so, in order to retain the articles in place, the panels forming the wraparound carrier are drawn in tightly by moving the securing flap 12 up along spacer panel 24 prior to being is secured therewith so as to provide a stable and easy stacking package.
The construction of the second, third and fourth embodiments are substantially the same as the first embodiment described and illustrated in Figures 4, 5, 6 and 7 and, therefore, only the construction of the end closure structure is described in any greater detail.
The articles A are 2o applied to the article retention structure by relative vertical movement during continuous forward feed, as shown in Figures 11 and 12, and before folding the base and side wall panels 216, 214, the end closure structure is formed. This is achieved by folding end wall panel 276 inwardly along fold line 275.

In use, the notch 266 functions to allow the tab 258 to protrude through the opening 270 to be engaged with an 25 article. There is a similar notch 268 provided adjacent to bracing tab 260 that functions in the same way.
There may further comprise an aperture 274 struck from one of the side panels and a corresponding recess portion 289 in glue flap 228 to provide an additional display window to 30 reveal part of the side wall of an article A.
_g_ Turning to the fourth embodiment illustrated in Figure 14, it is virtually identical to the third embodiment in its overall construction except for the details of the friction tabs. Like features of the third embodiment are designated by the same reference numeral with the prefix "3".
Therefore, only those differences between the third and fourth embodiments are described in any further detail.
In the fourth embodiment, the friction tab 358, again, is not co-extensive with bracing panel 350 and terminates short. However, an aperture or notch 366 is defined adjacent to the free end edge of the bracing panel 350 remote from fold line 354. In use, the notch 366 functions to to prevent the tab 358 from being exposed to view through opening 370. In other words, the notch 366 is struck from the friction tab 358 to cooperate with the opening 370 to provide a window to reveal the top portion of one of the articles. There is a similar notch 368 provided adjacent to the free end edge of bracing panel 352. The notch 368 functions to prevent friction tab 360 from being exposed to view through opening 372.
Turning to the construction of the carton formed from one of the blanks illustrated in Figures l, 2, 3 or 14, it is envisaged that the carton of the present invention can be formed by a series of sequential folding and gluing operations which can be performed in a straight line machine, so that the carton is not required to be rotated or converted to complete its 2o construction. The folding process is not limited to that described below and can be altered according to particular manufacturing requirements.
Turning now in particular to Figure 4, the blank 10 of the first embodiment is folded in direction X along fold line 40 to form the internal article retention structure. Thus, spacer panel 24 and retaining panel 26 are placed in face-contacting relationship with top panel 22 and upper second side wall panel 20 and are held in place by securing flap 28 to side wall panel 18 by glue G or other suitable securing means known in the art. The carrier is at an intermediate stage construction, shown in Figure 5, whereby it is in flat collapsed condition ready to be supplied to a user, for example a bottler, to be loaded with articles, described below.
In order to construct and load the carrier, the retention structure and brace are formed, whereby panels 20, 22, 24 and 26 forming the article retention structure are folded along fold lines 38, 40, 42 and 44 in direction Y so as to form a tubular structure T as shown in Figure 6.
This folding action reveals friction tabs 58 and 60 that are ready to form the brace.
Thereafter, the brace is formed by folding brace panels 50 and 52 in directions W and V
respectively along fold lines 54 and 56 as shown in Figure 7 to take up a bracing position.
The bracing panels 50, 52 act as braces by their free edges coming into contact with opposed spacer panels 24, 28 or, as the case may be, side walls. Additionally, or alternatively, the bracing tabs may abut the top wall to provide a brace between the top and retention panels 22, 26.
In those embodiments with friction tabs 58 and 60 are folded along fold lines 62 and 64, so as to come into face contacting relationship with spacer panel 24. It is envisaged that in some embodiments the spacer panels are dispensed with, in which case the friction tabs come into face contacting relationship with the side walls.
Turning again to the embodiment shown in Figure 7, the brace panels 50, 52 are held in place by the frictional engagement between the inner face of spacer panel 24 and the tabs 58 and 60 respectively, thereby to maintain the tubular structure in a set-up condition.
Optionally, glue 2o may be applied to friction tabs 58, 60 so that they are secured to spacer panel 24. The tabs 58, 60 may be shaped so as to protrude in part 59, 61 (Figure 9), through apertures 90, 92.
Beneficially, this allows tabs 58, 60 to be secured directly to an outer panel of the carrier, for example, securing tab 12 to provide a structure of improved rigidity.
In order to complete construction of the carton, the panels forming the wraparound carrier are formed, so that the base panel 16 and first side wall panel 14 are folded out of alignment with second side wall panel 18 along fold lines 34 and 32 respectively as shown in Figure 8.
Prior to constructing the wraparound carrier, the articles are applied to the carrier by relative 3o movement between the article A and the tubular structure T, preferably during continuous forward movement. The articles are grouped in a two-by-two array although is anticipated that other groupings or even a single article could be packaged without departing from the scope of the invention.
As shown in Figures 9 and 10 the articles pass through apertures 90 and 92 to be held in place within the tubular structure T. In some embodiments, suitable retention means engage the upper part of the articles) to prevent any movement within the apertures 90, 92. Thereafter, the side and base walls are folded as described above and the first side wall panel 14 is secured to the article retention structure by securing glue flap 12 to spacer panel 24 by glue or other suitable means known in the art. Thus, the carton is in set-up and loaded condition as to shown in Figure 10.
It will be seen that the articles to be packaged, in this embodiment, are flexible foil pouches and so, in order to retain the articles in place, the panels forming the wraparound carrier are drawn in tightly by moving the securing flap 12 up along spacer panel 24 prior to being is secured therewith so as to provide a stable and easy stacking package.
The construction of the second, third and fourth embodiments are substantially the same as the first embodiment described and illustrated in Figures 4, 5, 6 and 7 and, therefore, only the construction of the end closure structure is described in any greater detail.
The articles A are 2o applied to the article retention structure by relative vertical movement during continuous forward feed, as shown in Figures 11 and 12, and before folding the base and side wall panels 216, 214, the end closure structure is formed. This is achieved by folding end wall panel 276 inwardly along fold line 275. In addition, glue flaps 278 and 280 are folded along fold lines 282 and 284 respectively around the articles A, as illustrated in Figure 12.
Thereafter, the 25 base and/or first side wall panel 214 may be secured to the glue flaps 278 and/or 280 respectively to retain the end closure panels 276 in place. Thus, the carton is in a set-up condition as shown in Figure 13.
a In the embodiment shown in Figure 12, the friction tabs 258 and 260 axe engaged in apertures 30 270 and 272 respectively, to retain the brace panels 250 and 252 in a bracing position.
The present invention and its preferred embodiments relate to an arrangement for forming a brace in an article retention structure formed from material that also forms one or more article receiving apertures. However, it is anticipated that the invention can be applied to a variety of carriers and not limited to those of a wraparound type described above.
It will be recognised that as used herein, directional references such as "top", "base", "end", "side", "inner", "outer", "upper" and "lower" do not limit the respective panels to such orientation, but merely serve to distinguish these panels from one another.
Any reference to "hinged connection" or fold line should not be constructed as necessarily referring to a single 1o fold line only; indeed, it is envisaged that "hinged connection" can be formed from one or more the following, score line, a frangible line or a fold line, without departing from the scope of the invention.
It should be understood that various changes can be made within the scope of the present 15 invention. For example, the size and shape of the panels and apertures rnay be adjusted to accommodate articles of different size or shape, alternatively top and base closure structures may be used. The carton may accommodate more than one article in different arrays. In the illustrated embodiment, there comprise four articles arranged in two-by-two array although, of course, other arrays are envisaged.
