This invention relates to an article carrier of the basket type adapted to accommodate a plurality of articles, such as bottles and to a blank for forming the carrier. Normally a basket carrier for bottles includes a central (medial) partition structure which incorporates a handle structure by which the carrier can be lifted and carried and the bottles are arranged in rows on either side of the partition structure. More often than not, bottles are separated from one another by transverse partition panels extending from each side of the medial partition structure to the adjacent side wall of the carrier. Hence, in this type of arrangement the bottles are accommodated in individual cells of the carrier although such cells are not essential.
Known basket carriers require a series of complex folds to form partition structures, which may require the blank to be rotated or inverted during construction, thus slowing the process down.
One example of a basket style carrier is illustrated in U.S. Pat. No. 3,570,706 which discloses a carrier having side and end walls, a bottle partition structure and bottom wall with sloping panel portions provided with bottle apertures. The bottle apertures have overlying tabs to protect part of the bottle in the cut out.
Another example is illustrated in CH 670 432 which illustrates a carrier blank having side and end walls, a medial partition structure connected to the side wall by an internal partition and to the opposing end walls.
The complex structure of known basket carriers requires a large amount of board to be used with an irregular shape of blank profile, thereby resulting in material wastage, which is undesirable.

In
The blank 80 forms one side of the partition structure and comprises a pair of transverse partition panels 82, 84 struck from a medial partition panel 86. Transverse partition panel 82 is struck from medial panel 86 by cut line 87 and is connected thereto along fold line 88. Likewise, transverse partition panel 84 is struck from medial panel 86 by cut lines 89, 90 and is connected thereto along fold line 92. In this embodiment fold line 92 is interrupted by cut line 87 which extends into transverse partition panel 84 to define a glue flap 94 foldably connected to transverse partition panel 82 along fold line 96. A second glue flap 98 may be connected to transverse partition panel 84 along fold line 99. Optionally, the glue flaps 94, 98 include protruding elements 91 defined by cut line 93 which interrupts the glue flap fold line. In use, the protruding elements increase the surface area of the glue flap to be secured. A hook 97 may be provided along a lower edge of medial panel 86 to provide a detachable connection to the base structure.
The blank 80a is similar to blank 80 and therefore like panels are designated by the same reference numeral with addition of letter “a”. Therefore, only the differences between blank 80 and blank 80a are described in more detail. An end flap 95a may be provided which is foldably connected to medial panel 86a along fold line 79a. In use, end flap 95a is secured to end panel 18. In use, tab 93a is adapted to be secured to medial support panel 12, 24 described below.
It is envisaged that the number and position of the transverse partition panels of each blank can be changed according to the number of article receiving cells required.
The construction of a completed carrier of the first embodiment shown in
Thus, blanks 80 and 80a are secured to blank 10. In this embodiment, the flaps 94, 98 are secured to side panel 16 and medial panel 86 is secured to handle panel 38 by glue or other suitable means. Likewise, glue flaps 94a and 98a are secured to side panel 20 and medial partition panel 86a is secured to handle panel 52 by glue or other suitable means. Thus the carton is at a first stage of construction, shown in FIG. 2A. Thereafter, handle support panel 68 is folded about fold line 66 and into face contacting relationship with handle panel 52 so that apertures 70 and 58 are aligned. End panel 18 is folded out of alignment with the adjacent side panels 16, 20 along fold lines 30, 19, 32 respectively such that intermediate panels 50, 64 are in face contacting relationship with each part 18a, 18b of end panel respectively. In some embodiments, intermediate panels 50, 64 are secured to end panel 18 by glue or other suitable means in the art.
Medial support panels 12, 24 are also folded into face contacting relationship with respective end panels 14, 22 and handle panels 38, 58 and may be secured together by glue or other suitable means in the art. The outer panels 18b, 20, 22 forming one side of the partition are folded into face contacting relationship with the outer panels 18a, 16, 14 forming the other side of the partition.
By folding the panels in this way, the two sides of the basket carrier are brought into a face to face relationship with each other and the handle panels 52, 68 are secured together with the inner face of handle panel 38 by glue or other means known in the art. Preferably, tab 93a is secured to medial panel 86 and medial support panels 12, 24 may be secured to the portions of respective medial panels 86, 86a respectively by glue or other means known in the art. In those embodiments with flap 95a, it is secured to end panel 18.
The carton is then at an intermediate stage, shown in FIG. 2B: a completed collapsed article carrier whereby second end panel 22, second side panel 20 and outer handle panel 52 are placed in a face to face relationship with first end wall 14, first side panel 16 and handle panel 38 respectively. The carton of the first embodiment is commonly referred to as an “arrow profile” pack, because the end panels are folded about a central fold line to define a leading edge 37 and two trailing edges defined by fold lines 30 and 32.
To erect the article carrier, the leading and trailing edges of the collapsed carrier are moved inwardly towards each other. This causes end panels 14, 22 and 18, and side panels 16 and 20 moved from a flat collapsed condition into a substantially rectangular configuration which facilitates the construction of individual cells. Thus, transverse partition panels 82, 84 are automatically deployed by moving out of alignment with first side panel 16 and handle panel 38; and are folded about fold lines 88 and 92 respectively such that transverse partition panels 82, 84 are in a substantially perpendicular relationship with respect to handle panel 38 and side panel 16. As illustrated in
The carton is then ready to receive articles which are loaded by relative vertical movement between the articles and carrier during forward feed movement well known in the art by which the articles enter their respective cells through the open bottom of the carrier. Alternatively, the bottles can enter their respective cells through the top of the carrier.
Thereafter, the base is formed whereby base panels 72 and 74 are brought into an overlapping relationship and connected together by securing means well known in the art. In this embodiment glue flap 76 is glued to base panel 74. The base panels may be held in place prior to loading and/or after loading by engagement of the base panels 72, 74 with the hooks 97, 97a shown in
In use, handle tabs 46, 60 are folded about handle panels 38, 52 to further secure hand structure H and the carton. Thus the carton of the first embodiment is in a set up condition as shown in
Turning to the construction of the second embodiment shown in
A first handle panel 138 is disposed adjacent first end panel 118 and first side panel 116 and is separated from the side and end panels by cut lines 140, 142 extending from fold line 126 and into end panel 118. Handle panel 138 is hingedly connected to an upper edge of end panel 118 by a nick portion. The point of connection should be in a central part, if it is desired for the handle to be centrally located. Handle panel 138 is foldably connected along its opposing edge to medial support panel 112 by an intermediate panel 150. In this embodiment, intermediate panel 150 is hingedly connected to a side edge of handle panel 138 along fold line 151, and to medial support panel along fold line 30 as shown in FIG. 4A. Handle panel 138 may include a hand aperture 144. In this embodiment, a hand cushioning flap 146 is connected along fold line 148 to an upper edge of hand aperture 44.
Preferably, a second handle panel 152 is provided which is disposed adjacent a second side panel 120 and second end panel 122 and is separated from the side and end panels by cut lines 154 and 156 respectively which extend from fold lines 132 and into end panel 122. Handle panel 152 is hingedly connected to an upper edge of end panel 122 by a nick portion and to the opposing end panel 118 by an intermediate panel 164. In this embodiment, intermediate panel 164 is foldably connected to a side edge of handle panel 152 along fold line 165 and to end panel 118 along fold line 132, shown in FIG. 4A. Second handle panel 152 includes a hand aperture 158. In this embodiment, a hand cushioning flap 160 is connected along fold line 162 to an upper edge of hand aperture 158.
In this embodiment, a triple ply handle structure is provided which includes a pair of handle support panels 168, 169. Each support panel 168, 169 is foldably connected to opposing side edges of handle panel 138 and are foldable so that the opposing side edges of each support panel are brought into abutment when the support panels are brought into face contacting relationship with handle panel 138. More particularly, handle support panel 168 is foldably connected to handle panel 138 along fold line 155 and includes a hand aperture 170, positioned intermediate upper and lower edges of handle support panel 168. Hand aperture 170 is positioned to be aligned with hand apertures 154, 158 in a set up carton. Similarly, handle support panel 169 includes hand aperture 171.
A base structure is formed from panels 172, 174 and securing means which in this embodiment is substantially the same as the first embodiment and is not, therefore described in any greater detail.
The partition structure of the article carrier is formed from a second blank 180. The blank 180 comprises a pair of transverse partition panels 182, 184 struck from a medial partition panel 186. Transverse partition panel 182 is struck from medial panel 186 by cut lines 185, 187 and 190 and is foldably connected thereto along interrupted fold line 188. It will be seen from
Likewise, transverse partition panel 196 is struck from medial panel 186 by cut lines 191, 193 and 195 and is foldably connected thereto along fold line 192. Interrupted fold line 192 is disposed intermediate the opposing ends of transverse partition panel 184 to define a two part partition panel 115, 196. There may further comprise glue flap 198 foldably connected to transverse partition panel 184 along fold line 197.
There may further comprise medial glue flaps 176, 178 foldably connected to opposing side edges of medial panel 186 along fold lines 177 and 179 respectively.
The construction of the carton is substantially identical to that described in the fifth embodiment illustrated in
A common feature shared by both the first and second embodiments relates to the handle panel structure H. More particularly, the handle panels and, as the case may be, the handle support panels are co-planar. The upper edges of the handle panels are co-linear as shown in
The construction of the third embodiment is described by reference to
It will be seen from
In this embodiment, hooks 297 and 297a are provided along lower edge of medial support panels 212 and 224 to be engaged in corresponding apertures in the base structure, thereby to maintain the carton in a set up condition prior to loading and/or after loading.
In this embodiment, the handle H (
The blanks 280, 280a for forming the medial transverse partition structures, shown in
The shape of the upper edges of the blank and more particularly the handle support panel 268, handle panel 238 and intermediate panel 250 and end panel 218a are shaped to receive the corresponding panels of the next adjacent blank 210. As illustrated in
Preferably, the shape of the base panels 274, 272 are substantially trapezoidal so that the lower edges of adjacent blanks marry up thereby to minimise the amount of board required.
The construction of the third embodiment is similar to the first embodiment whereby the medial support panels 212, 224 are folded into face contacting relationship the medial panel 286 is secured to medial support panel 212, handle panel 238 and glue flaps 294, 298 are secured to side panel 216, but medial panel is otherwise unconnected to blank 210, as shown in FIG. 7A. Likewise, medial panel 286a is secured to medial support panel 224, handle panel 252 and the glue flaps 294a and 298a are secured to side panel 220. Thus, the carton is at a first stage of construction, shown in FIG. 7A.
Thereafter the blank is folded about fold lines 230, 219 and 232 so that second end panel 222, second side panel 220 and second handle panel 252 are placed in a face to face relationship with first end wall 214, first side panel 216 and handle panel 238 respectively to provide a package in a flat collapsed condition in an “arrow profile” and lead edge is defined by fold line 226, 236 and there comprises two trailing edges defined by fold lines 230 and 232 respectively. In those embodiments with medial support flaps 295 and 295a they are secured to end panel 218 as shown in FIG. 7B.
To erect the article carrier, the leading and trailing edges of the collapsed carrier moved inwardly towards each other, as described above in the first embodiment to construct the individual cells. The articles enter their respective cells C1, C2, C3 to complete the load process, ready to be supplied to the user, and the handle structure H and base structure are also formed in like manner to provide a carton similar to that illustrated in FIG. 8.
The fourth embodiment of the carton is illustrated in
The fifth embodiment is illustrated by reference to
The shape of the upper edges of the blank 410 and more particularly handle panels 438, 452, intermediate panels 450, 464 and end panels 418 and 422 are shaped to receive corresponding panels of the next adjacent blank 410. As illustrated in
The construction of the completed carrier of the fifth embodiment shown, in
Thus, blank 480 is secured to blank 410. In this embodiment, glue flap 494 is secured to side panel 416 and medial panel 486 is secured to handle panel 438 so that handle support panel 468 is aligned with handle panel 438. Medial support flap 478 is secured to end panel 418 by glue or other suitable means known in the art. Thus, the carton is at a first stage of construction shown in FIG. 12A. Thereafter glue flap 412 is folded about fold line 426 into face contacting relationship with side panel 416 and the outer panels 420 and 422 are folded about fold line 432 into face contacting relationship with medial panel 406. End panel 422 is secured to glue flap 412 and transverse glue flap 498 is secured to side wall 420. Handle panel 452 is secured to the opposing face of handle support panel 468 and medial support panel 476 is secured to end panel 422.
By folding and securing the panels in this way the two sides of the basket carrier are brought into face to face relationship such that the article carrier is in a completed and collapsed condition, shown in
To erect the article carrier, the leading and trailing edges of the collapsed carrier are moved inwardly towards each other, this causes end panels 422 and 418 and side panels 416 and 420 to be moved from a flat collapsed condition into a rectangular configuration which facilitates automatic construction of the individual cells. Thus, transverse partition panels 482 and 484 are moved out of alignment with first and second side panels 416, 420 respectively and are folded about fold lines 488 and 492 such that the transverse partition panels are in a substantially perpendicular relationship with respect to handle panel 468 and side panels 416 and 420. It will be seen from
The carton is then ready to receive articles which are loaded a relative vertical movement between the articles and the carrier during forward feed movement well known in the art by which the articles enter their respective cells through the open bottom of the carrier. Alternatively, the bottles can enter their respective cells through the top of the carrier. Thereafter the base is formed in substantially the same manner as described above whereby base panels 472, 474 are connected together by securing means. Similarly handle tabs 446, 460 are folded about handle 468, 452 to further secure hand structure H and the carton. Thus the carton of the fifth embodiment is in a set up condition as shown in
The sixth embodiment of the invention is illustrated in
As regards the blank 510 for forming the outer panels, it will be seen from
A two part blank 580, 580a is provided for forming the medial and transverse partition structures shown in FIG. 14B and is substantially similar to the third embodiment illustrated in FIG. 5B. It will be seen that the position of tabs 593, 593a differ from the third embodiment although each tab is adapted to be secured to the other medial panel 586, 582 by glue or other suitable means known in the art and to separate adjacent cells. In this embodiment, the protruding elements E of each tab overlap to be secured together, shown in FIG. 15B.
The construction of the sixth embodiment is similar to the fifth embodiment described above whereby the transverse partition panels are secured to respective side panels, the medial panel is secured to the handle panel and the medial support flaps secured to respective end panels shown in FIG. 15A. Thereafter one side of the basket carrier is folded about fold line 532 into face contacting relationship with the medial structure and is secured together as described above to form a flat collapsed carrier illustrated in FIG. 15B.
To erect the carrier of the sixth embodiment, the leading and trailing edges of the collapsed carrier move inwardly towards each other as described above in the fifth embodiment to construct individual cells and the articles enter their respective cells C1, C2, C3 to complete the loading process, ready to be supplied to the user. The handle structure H and base structure are also formed in like manner to provide a fully erected carton similar to that illustrated in FIG. 16. The advantages of the shape of the upper edges of the blank and base of the present embodiment have already been referred to in respect of the fifth embodiment above and are not therefore described in any greater detail.
The seventh embodiment of the invention is illustrated in
It can be seen from
In this embodiment, the outer blank further comprises a pair of transverse partition panels 631, 633 foldably interconnecting handle panel 638 and side panel 616. There further comprises a pair of transverse partition panels 651, 653 foldably interconnecting handle panel 652 and side panel 620. Glue flaps 650 and 664 are provided to be secured to the adjacent end panel 622, 618 respectively.
A two part blank 680, 680a is provided for forming the medial and transverse partition structures shown in FIG. 17B and is substantially similar to the third embodiment illustrated in FIG. 5B. Therefore, only the differences are described. The transverse partition panels 682, 684; 682a, 684a are constructed in a different manner and, indeed, it is not necessary for glue flaps to be included because these panels can be secured to panels 631, 633; 651, 653 respectively. It will be seen that the position of tabs 693, 693a differ from the third embodiment although each tab is adapted to be secured to the other medial panel 686, 686a by glue or other suitable means known in the art by the protruding elements shown in FIG. 18B.
The construction of the seventh embodiment is similar to the some of the preceding embodiments described above, whereby the transverse partition panels are secured to respective side panels, the medial panel is secured to the handle panel and the medial support flaps secured to respective end panels shown in FIG. 18A. Furthermore, the transverse partition panels 684, 682; 684a, 682a are secured to the adjacent transverse partition panels 633, 631; 651, 653 of the outer blank 610. Thereafter one side of the basket carrier is folded about fold line 632 into face contacting relationship with the medial structure and is secured together as described above to form a flat collapsed carrier illustrated in FIG. 18B.
To erect the carrier, the leading and trailing edges of the collapsed carrier move inwardly towards each other as described above in the fifth embodiment to automatically construct individual cells and the articles enter their respective cells C1, C2, C3 to complete the loading process, ready to be supplied to the user. The handle structure H and base structure are also formed in like manner to provide a fully erected carton similar to that illustrated in FIG. 19. The advantages of the shape of the upper edges of the blank and base of the present embodiment have already been referred to in respect of the fifth embodiment above and are not therefore described in any greater detail. A further advantage of the present invention is that the blanks forming the partition structure can be reduced in width because, it is not necessary for the transverse partition panels 682, 684 to extend the width W of the cell as the outer transverse panels provide the rigidity.
Referring now to
In this embodiment, the carrier is formed from a two part blank and the blank 710, forming the outer panels, includes in longitudinal series a first medial support panel 712, first end panel 714, first side panel 716, second end panel 718, second side panel 720, third end panel 722 and second medial panel 724 hingedly connected one to the next along lateral fold lines 726, 728, 730, 732, 734 and 736 respectively. There may further comprise a lateral fold line 719 intermediate fold lines 730 and 732 for dividing second end panel 718 into two parts (718a, 718b) to form an “arrow profile” basket carrier, hereinafter described.
A first handle panel 738 is disposed adjacent second end panel 718 and first side panel 716 and is separated from these side and end panels by cut line 742. Cut line 742 extends between fold lines 728 and 719. Handle panel 738 is hingedly connected to second end panel 718 along an extension of fold line 719 which forms part of one side edge of first handle panel 738. Handle panel 738 is connected to the first end panel 714 by means of an intermediate panel 750 which is hingedly connected to the side edge of handle panel 738 along fold line 751, and to first end panel 714 along fold line 728.
Handle panel 738 may include a hand aperture 744. In this embodiment, a hand cushioning flap 746 is connected along fold line 748 to an upper edge of hand aperture 744.
A second handle panel 752 is disposed adjacent second side panel 720 and second end panel 718 and is separated from these side and end panels by cut lines 754, 765. Cut lines 754, 756 extend between fold lines 719 and 734. Handle panel 752 is hingedly connected to handle panel 738 along fold line 719. Handle panel 752 is connected to the third end panel 722 by means of an intermediate panel 764 which is hingedly connected to the side edge of handle panel 752 along fold line 766, and to end panel 722 along fold line 734.
Handle panel 752 may include a hand aperture 758. In this embodiment, a hand cushioning flap 760 is connected along fold line 762 to an upper edge of hand aperture 760.
In this embodiment, a triple ply handle structure is provided. Handle support panel 768 is disposed adjacent part of intermediate panel 750 and the medial support panel 712. Handle support panel 768 is hingedly connected to a side edge of first handle panel 738 along fold line 751, but is otherwise separated from the blank. In alternative embodiments, handle support panel may alternatively be connected to second handle panel 752. A hand recess 770 is provided and is preferably positioned to be aligned with the hand apertures 744 and 758 in a set up carton.
Hooks 797, 797a may be provided along lower edges of first and second medial panels 712 and 724 to provide a detachable connection to the base structure.
There further comprises a base structure which in this embodiment is provided by base panels 772, 774 foldably connected to side panels 716, 720 respectively. Suitable securing means is provided for securing the base panels together. For example, a glue flap 776 is connected to the base panel 772. Alternatively, locking tabs struck from base panel and a complementary pair of locking apertures are struck from second base panel to receive and retain the locking tabs, as is well known. It will be understood by those skilled in the art that other methods of interlocking the base panels together during construction can be adopted and the invention is not limited to those features illustrated in the embodiments or described above.
As shown in
A second medial partition panel 786a substantially mirrors the first 786, along fold line 791 and therefore like panels are designated by the same reference numeral with addition of letter “a”. Therefore, only the differences between blank 780 and blank 780a are described in more detail.
A projecting portion 785 of panel 786a is provided so as to cooperate with handle support panel 768 and thereby ensure that the handle is triple ply throughout. A corresponding cutaway portion is included in the opposite edge of the blank to minimise paperboard wastage if multiple blanks are struck in a tessellating pattern.
It is envisaged that the number and position of the transverse partition panels of each blank can be changed according to the number and size of article receiving cells required.
The construction of a completed carrier of the eighth embodiment shown in
In this embodiment, the flaps 794, 798 are secured to side panel 716 and medial panel 786 is secured to handle panel 738 by glue or other suitable means. Likewise, glue flaps 794a and 798a are secured to side panel 720 and medial partition panel 786a is secured to handle panel 752 by glue or other suitable means. Thus the carton is at a first stage of construction, shown in FIG. 21A.
Thereafter, handle support panel 768 is folded about fold line 751 and into face contacting relationship with handle panel 738 so that recess 770 and aperture 758 are aligned. First and third end panels 714 and 722 are folded inwardly along fold lines 728 and 734 respectively, such that medial support panels 712 and 724 may be secured to medial panels 786 and 768a respectively using glue or other suitable means known in the art. Second end panel 718 is folded in half along fold line 719 such that intermediate panels 750, 764 are in face contacting relationship with first end panel 714. In some embodiments, intermediate panels 750, 764 are secured to first end panel 714 by glue or other suitable means in the art.
Handle panels 738, 752 may be secured together by glue or other suitable means in the art. The outer panels 718b, 720, 722 forming one side of the partition are folded into face contacting relationship with the outer panels 718a, 716, 714 forming the other side of the partition.
By folding the panels in this way, the two sides of the basket carrier are brought into a face to face relationship with each other and the handle panels 752, 768 are secured together with the inner face of handle panel 738 by glue or other means known in the art. Preferably, tab 793a is secured to tab 793.
The carton is then at an intermediate stage, shown in FIG. 21B: a completed collapsed article carrier whereby third end panel 722, second side panel 720 and outer handle panel 752 are placed in a face to face relationship with first end panel 714, first side panel 716 and handle panel 738 respectively. The carton of the first embodiment is commonly referred to as an “arrow profile” pack, because the end panels are folded about a central fold line to define two trailing edges 736, 726 and a leading edge defined by fold lines 719.
To erect the article carrier, the leading and trailing edges of the collapsed carrier are moved inwardly towards each other. This causes end panels 714, 722 and 718, and side panels 716 and 720 moved from a flat collapsed condition into a rectangular configuration which facilitates the construction of individual cells. As illustrated in
The carton is then ready to receive articles which are preferably loaded by relative vertical movement between the articles and carrier during forward feed movement as is well known in the art, by which the articles enter their respective cells through the open bottom of the carrier. Alternatively, the bottles can enter their respective cells through the top of the carrier.
Thereafter, the base is formed whereby base panels 722 and 724 are brought into an overlapping relationship and connected together by securing means well known in the art. In this embodiment glue flap 776 is glued to base panel 774. The base panels may be held in place prior to loading and/or after loading by engagement of the base panels 772, 774 with the hooks 797, 797a shown in
In use, handle tabs 746, 760 are folded about handle panels 738, 752 to further secure hand structure H and the carton. Thus the carton of the first embodiment is in a set up condition as shown in
Turning to the construction of the ninth embodiment shown in
A first handle panel 838 is disposed adjacent first end panel 818 and first side panel 816 and is separated from the side and end panels by cut line 842 extending from fold line 826 and into end panel 818. Handle panel 838 is hingedly connected to an upper edge of end panel 818. The point of connection should be in a central part, if it is desired for the handle to be centrally located. Handle panel 838 is foldably connected along its opposing edge to glue flap 812 by an intermediate panel 850. In this embodiment, intermediate panel 850 is hingedly connected to a side edge of handle panel 838 along fold line 851, and to glue flap along fold line 826 as shown in FIG. 23A. Handle panel 838 may include a pair of hand/finger apertures 844, 844a. In this embodiment, a pair of hand cushioning flaps 846, 846a are connected along fold lines 848, 848a to upper edges of respective hand apertures 844, 844a.
A second handle panel 852 is disposed adjacent a second side panel 820 and second end panel 822 and is separated from the side and end panels by cut lines 854 and 856 respectively which extend from fold lines 832 and into end panel 822. Handle panel 852 is hingedly connected to an upper edge end panel 822 and to the opposing end panel 818 by an intermediate panel 864. In this embodiment, intermediate panel 864 is foldably connected to a side edge of handle panel 852 along fold line 865 and to end panel 818 along fold line 832. Second handle panel 852 preferably includes a pair of hand/finger apertures 858, 858a. In this embodiment, hand cushioning flaps 860, 860a are connected along fold lines 862 and 862a to an upper edge of respective hand apertures 858, 858a.
In this embodiment, a triple ply handle structure is provided which includes a handle support panel 868, hingedly connected to a side edge of handle panel 852 along fold line 855. Support panel 868 further includes a hand aperture 870, positioned intermediate upper and lower edges of handle support panel 868. Hand aperture 870 is positioned to be aligned with hand apertures 854, 858 in a set up carton. In alternative classes of embodiment, two apertures may be provided in handle support panel 868 that are arranged to be in register with the apertures on the handle panels in a set up carton.
A base structure is formed from panels 872, 874 which in this embodiment is substantially the same as the eighth embodiment and is not, therefore described in any greater detail.
The partition structure of the article carrier is formed from a second blank 880. The blank 880 comprises a pair of transverse partition panels 882, 884 struck from a medial partition panel 886. Transverse partition panel 882 is struck from medial panel 886 by cut lines 885 and 881 and is foldably connected thereto along fold line 888. Transverse partition panel 882 is further hingedly connected to glue flap 894 along fold line 896. As in the first embodiment, it is envisaged the number and position of the transverse panels can be altered according to the number of article receiving cells required.
Likewise, transverse partition panel 884 is struck from medial panel 886 by extensions of cut lines 885 and 881 and is foldably connected thereto along fold line 892. Transverse panel 884 is further hingedly connected to glue flap 894 along fold line 899. Medial partition panel is further hingedly connected at opposing edges thereof to glue flaps 883, 887 and 889.
A second medial panel 886a is hingedly connected to panel 886 along fold line 891. The second medial panel 886a is similar to panel 786, and therefore like panels are designated by the same reference numeral with the addition of the letter “a”. The only difference between the panels is that glue panel 894a does not in this embodiment extend into panel 886, in contrast to panel 894 which does extend into panel 886a.
The construction of the completed carrier of the ninth embodiment shown, in
Thus, referring to
By folding and securing the panels in this way the two sides of the basket carrier are brought into face to face relationship such that the article carrier is in a completed and collapsed condition, shown in FIG. 24B. The carton of the ninth embodiment is, commonly, referred to as a “parallelogram profile” pack because the leading edge is defined by fold line 432 and the trailing edge is defined by diametrically opposed edge provided by fold line 426.
To erect the article carrier, the leading and trailing edges of the collapsed carrier are moved inwardly towards each other, this causes end panels 822 and 818 and side panels 816 and 820 to be moved from a flat collapsed condition into a rectangular configuration which facilitates construction of the individual cells. Thus, transverse partition panels 882, 884, 882a, 884a are moved out of alignment with first and second side panels 820, 816 respectively and are folded about fold lines 888, 892, 888a and 892a, such that the transverse partition panels are in a substantially perpendicular relationship with respect to handle panel 868 and side panels 816 and 820. It will be seen from
The carton is then ready to receive articles which are preferably loaded a relative vertical movement between the articles and the carrier during forward feed movement well known in the art by which the articles enter their respective cells through the open bottom of the carrier. Alternatively, the bottles can enter their respective cells through the top of the carrier. Thereafter the base is formed in substantially the same manner as described above whereby base panels 472, 474 are connected together by securing means. Similarly handle tabs 446, 460 are folded about handle 468, 452 to further secure hand structure H and the carton. Thus the carton of the ninth embodiment is in a set up condition as shown in
A common feature shared by both the eighth and ninth embodiments relates to the handle panel structure H. More particularly, the handle panels and, as the case may be, the handle support panels are co-planar. The upper edges of the handle panels are co-linear as shown in
A further common feature is the use of a single medial blank which is folded along one edge to form the medial and transverse panels along both sides of the handle panel. In certain circumstances this may simply mechanisation of the erection process.
It will be recognised that as used herein, directional references such as “top”, “base”, “end”, and “side” do not limit the respective panels to such orientation, but merely serve to distinguish these panels from one another. Any reference to hinged connection should not be construed as necessarily referring to a single fold line only: indeed it is envisaged that hinged connection can be formed from one or more of one of the following, a score line, a frangible line or a fold line, without departing from the scope of invention.
The present invention and its preferred embodiments relate to an article carrier which is shaped to provide satisfactory strength to hold the bottle securely but with a degree of flexibility so that load transferred to the handle is absorbed by the carrier. The shape of the blank minimises the amount of paperboard required. The carrier can be applied to an array of bottles by hand or automatic machinery. It is anticipated that the particular features of each of the embodiments described above are interchangeable, without departing from the scope of the invention.
