Description

Background of the Invention

The present invention generally relates to cartons for holding and dispensing containers or other types of articles. Moreover, the present invention relates to a blank for forming such a combination shipping and dispensing carton and to a method of enclosing and displaying a plurality of articles making use of such a combination shipping and dispensing carton.
Cartons are typically shipped in bulk quantities. During shipping, the cartons may be vertically stacked upon each other in order to maximize the amount of product shipped in a particular vessel. The amount of product shipped may depend, however, on the load-bearing capacity of the stacked cartons. It is therefore sometimes desirable to produce cartons having high rigidity and/or strength in compression for shipping, and for other purposes such as the protection of the carton contents in general.
A conventional method for increasing the strength of a carton is to produce the carton from a blank of a different, stronger board material, or to produce the blank from the same carton material but of greater thickness. Such methods typically increase the costs associated with manufacturing the carton, with the material costs of manufacture generally increasing according to the cost of increasing the strength and/or thickness of the entire blank. Some sections of the blank, however, may not be load-bearing, and the additional costs associated with increasing the strength of non load-bearing bearing sections of the blank are wasted.
Furthermore, a need often exists for a carton suitable for containing the product or containers during shipping and for displaying and dispensing the product or containers. Combination shipping and dispensing cartons are disclosed e.g. in US 3090483 A and GB 1218016 A . Such combination shipping and dispensing cartons typically comprise tear-away portions which are confined by tear lines and are to be turn-off in order to at least partially expose the articles for easy grasping. The cartons known from US 3090483 A and GB 1218016 A moreover comprise a tear feature that allows to divide the carton into two halves.
Dispensing features typically conflict with rigidity of the carton. The present invention aims at providing for a satisfactory carton suitable for both, safely containing the articles during shipping as well as displaying and dispensing the articles.

Detailed Description of the Exemplary Embodiments

The present invention generally relates to cartons that contain articles such as pouches, containers, bottles, cans, etc. The articles can be used for packaging food and beverage products, for example. The articles can be made from materials suitable in composition for packaging the particular food or beverage item, and the materials include, but are not limited to, aluminum and/or other metals; glass; plastics such as PET, LDPE, LLDPE, HDPE. PP, PS, PVC, EVOH, and Nylon; and the like, or any combination thereof.
Cartons according to the present invention can accommodate articles, or subset of articles, of any shape. For the purpose of illustration and not for the purpose of limiting the scope of the invention, the following detailed description describes leverage containers (e.g., beverage pouches) as disposed within the carton embodiments. In this specification, the terms "lower," "bottom," "upper" and "top" indicate orientations determined in reflation to fully erected and upright carton.
Fig. 1 is a plan view of interior sides of a primary blank 6 and first and second reinforcing blanks 8, 9. The blanks 6, 8, 9 are used to form a carton 100 (illustrated in Figs. 3 and 4) according to a first embodiment of the invention. The interior sides of the blanks 6, 8, 9 will generally be disposed in the interior of the erected carton 100. The blanks 6, 8, 9 may be combined, for example, into a blank 10 (Fig. 2) having multi-ply sections formed from adhering or otherwise attaching the first and second reinforcing blanks 8, 9 to the primary blank 6. As discussed in further detail below, the primary blank 6 can have a periphery that is complimentary to portions of the peripheries of the reinforcing blanks 8, 9.
Referring to Fig. 1 illustrating a first reference example, the primary blank 6 comprises a first side panel 20 foldably connected to a bottom panel 30 at a first transversely extending fold line 31, a second side panel 40 foldably connected to the bottom panel 30 at a second transverse fold line 41, and a first top panel 50 foldably connected to the second side panel 40 at a third transverse fold line 41. A second top panel 60 is foldably connected to the first side panel 20 at a fourth transverse fold line 61, and a third top panel 70 is foldably connected to the second top panel 50 at a fifth transverse fold line 71. The bottom panel 30 is foldable at its spine or midpoint at a sixth transverse fold line 35 extending across the width of the bottom panel.
The first side panel 20 is foldably connected at each and to a first side end flap 22. The bottom panel 30 is foldably connected at each end to two bottom end flaps 32. The bottom end flaps 32 are separated by transversely extending cuts 34, which more specifically typically are slits. The second side panel 40 is foldably connected at each end to a second side end flap 42. The first top panel 50 is foldably connected at each end to a first top end flap 52. The second top panel 60 is foldably connected at each end to a second top end flap 62. Handle apertures or knockouts 54 may be formed in one or both of the first and third top panels 50, 70. The end flaps 22, 32, 42, 52, 62 extend along a first and a second marginal area of the blank 6, and may be connected at first and second longitudinally extending fold lines 65, 66. The longitudinal fold lines 65, 66 may be straight, or they may be offset at one or more locations to account for, for example, blank thickness.
The primary blank 6 includes a line of separation (broadly "dispensing feature"), generally indicated 68 contending the length of the blank, In the embodiment of Fig. 1-4, the line of separation 68 comprises two spaced apart tear lines 75, 77 forming a tear strip 79 removably attached to the blank 6. In the illustrated embodiment, the tear strip 79 extends between the longitudinal ends of the blank and comprise a portion of the third top panel 7, the first top panel 50, the second side panel 40, the top panel 30, the first side panel 20, and the second top panel 60. The tear strip 79 could be otherwise shaped and arranged. For example, the tear strip 79 could be replaced with a single tear line.
The first reinforcing blank 8 has a perimeter that may be in part generally complementary to a part of the first marginal area of the primary blank 6. The first reinforcing blank 8 is meant to overlie a part of the first marginal area of the primary blank 6 in order to reinforce the blank 6. The first reinforcing blank 8 includes a strip 80 of sequentially arranged rectangular reinforcing panels 81, 82, 83, 84, 85, 86, 87, and foldably attached reinforcing end flaps 62', 22', 32', 32', 42', 52'. During erection, the blank 8 is placed over the primary blank 6 so that the reinforcing end flaps 62', 22', 32', 32', 42', 52' of the first reinforcing blank 8 overlie and generally conform in shape to corresponding end flaps 62, 22, 32, 32, 42, 52, respectively, of the primary blank 6. The sequentially arranged reinforcing panels 81, 82, 83, 84, 85, 86, 87 are aligned with respective panels 60, 20, 30, 40, 50, 70 of the primary blank 6 so that the reinforcing blank 8 folds along the transverse fold lines 61, 31, 35, 41, 51, 71 in the primary blank 6.
Similarly, the second reinforcing blank 9 has a shape that may be in part generally complementary to a part of the second marginal area of the primary blank 6, and is meant to overlie and reinforce a second part of the first blank 6. The second reinforcing blank 9 includes a strip 90 of sequentially arranged rectangular reinforcing panels 91, 92, 93, 94, 95, 96, 97, and reinforcing end flaps 62', 22', 32', 32', 42', 52'. During erection, the second reinforcing blank 9 is placed over the primary blank 6 so that the reinforcing end flaps 62'. 22', 32', 32', 42', 52' of the reinforcing bank 9 overlie and generally confirm in shape to the end flaps 62, 22, 32, 32, 42, 52 of the primary blank 6. The reinforcing panels 91, 92, 93, 94, 95, 96, 97 are aligned with respective panels 60, 20, 30, 40, 50, 70 of the primary blank 6 so that the second reinforcing blank 9 folds along the transverse fold lines 61, 31, 35, 41, 51, 71 of the primary blank 6. Portions of the second reinforcing blank 9 may be, for example, a mirror image of the first reinforcing blank 8, and certain common reference numerals are therefore used in the reinforcing blanks 8 and 9.
Fig. 2 illustrates the primary blank 6 and the reinforcing blanks 8, 9 combined into a multi-ply blank 10. In Fig. 2, the reinforcing blanks 8, 9 are placed over the respective first and second marginal areas of the primary blank 6 and secured thereto. Glue, for example, or other adhesives, or other means, may be used to secure the reinforcing blanks 8, 9 to the primary blank.
Figs. 2A-2C illustrate an exemplary method of erecting the multi-ply blank 10 (Fig. 2) into the carton 100. Certain elements of the blanks 6, 8, 9 referred to in the following description may not be visible in Figs. 2A-2C, and such elements can be found in Figs. 1 and 2. Fig. 2 illustrates the multi-ply blank 10 ready for erection. In Fig. 2A, the end flaps 22, 32, 32, 42, 52, 62 (along with the reinforcing end flaps 62', 22', 32', 32', 42', 52') and the top panels 50, 60, 70 are folded inwardly. In Fig. 2B, the exterior sides of the end flaps 62, 32 are adhered to the interior sides of the reinforcing end flaps 22', and the exterior sides of the end flaps 32 and 52 are adhered to the interior sides of the reinforcing end flaps 42'. Fig. 2C illustrates the partially erected blank 10 being folded in the direction of the arrows to bring the opposed halves of the partially erected carton together. The interior side of the third top panel 70 may be adhered to the exterior side of the second top panel 60 to complete erection of the carton 100, as shown in Fig. 3. One or more articles P (Fig. 4) may be loaded into the carton 100 at any time prior to fully closing the carton 100.
Figs. 3 and 4 illustrate the erected carton 100. The carton 100 may be, for example, generally parallelepipedal, and may have a closed or nearly closed configuration. In Fig. 3, the carton 100 rests on the bottom panel 30. The first and second side end flaps 22, 42 along with the reinforcing end flaps 22', 42' adhered thereto close the ends 53, 55 of the carton 100. The optional handle apertures 54 are accessible in the top panels 50, 70.
Fig. 4 illustrates the erected carton 100 with the tear strip 79 removed and the carton converted from a shipping carton to a two-piece dispensing carton. In the illustrated embodiment, the carton 100 is converted to the dispensing carton by grasping and removing the tear strip 79 to separate the carton into a first dispensing portion 25 and a second dispensing portion 45. Each of the first and second dispensing portion 25, 45 contains a respective subset of the articles P. As shown in Fig. 4, the first dispensing portion 2S is smaller than the second dispensing portion 45. Both the first and second dispensing portions 25, 45 have an open top for access to articles P contained therein. It is understood that the dispensing portions 25 could be alternatively shaped and sized. For example, in alternative embodiments, the two dispensing portions may be approximately equal in size. Further, the dispensing portions may be foldably attached along a fold line and more than two dispensing portions may be provided without departing from the scope of this invention.
The reinforcing blank 9, as well as the reinforcing blank 8 (illustrated in Fig. 1), provides additional strength and rigidity to the carton 100. For example, when the carton 100 is supported on the bottom panel 30 as shown in Fig. 3, the panels and flaps 92, 95, 22', 42' of the reinforcing blank 9, and the reinforcing panels and flaps 82, 85, 22', 42' of the reinforcing blank 8 extend vertically within the carton 100 interior and provide significant strength against vertical axial compression. Similarly, if the carton 100 is supported on either of its side panels 20, 40, the first and second reinforcing blanks 8, 9 provide significant additional axial compressive strength and rigidity to the primary blank 6.
Fig. 5 illustrates a multi-ply blank 110, according to a first embodiment of the invention. The blank 110 comprising a primary blank 106 and first and second reinforcing blanks 108, 109. In Fig. 5, like reference numbers as to the reference numbers shown in Pigs. 1 and 2 indicate like or similar elements, with the reference numbers in Fig. 5 being preceded by "1." The resultant multi-ply blank formed from the primary and reinforcing blanks 106, 108. 109 can be erected into a carton 200 (Figs. 6-8) using the method shown in Figs. 2A-2C.
The primary blank 106 is substantially identical to the primary blank 6, except the blank includes a line of separation (broadly "dispensing feature") 168 comprising a first tear line 169 in the first side panel 120 and the second top panel 160, and a second tear line 172 in the second side panel 140 and the top panels 150, 170. The two tear lines 169, 172 are connected by a longitudinal fold line 173 in the bottom panel 130 of the primary blank 106. The first tear line 169 has a first portion 141 extending longitudinally from the fold line 131 into the first side panel 120 and a second portion 143. The second portion 143 is generally V-shaped and extends from the first portion 141 into the second top panel 160 to the edge of the blank 106. The second tear line 172 has a first portion 146 extending longitudinally from fold line 141 into the second side panel 140 and a second portion 148 that is generally V-shaped and extending from the first portion across the first and second top panels 150, 170 to the edge of the blank 106.
As shown in Figs. 6-8, the carton 200 has a dispenser 107 including a removable dispenser panel 111 for forming a dispenser opening 113 in the carton. The dispenser panel 111 is formed in the top panels 150, 160, 170 and the first and second side panel 120, 140 by tearing along the tear lines 169, 172. To convert the carton 200 from the shipping carton to the dispensing carton, the dispenser panel 111 is removed by tearing along the respective second portions 143, 148 of the first and second tear lines 169, 172. Next, the carton 200 is further separated along respective first portions 141, 146 of the tear lines 169, 172. The carton 105 is then folded along fold line 173 to form the first and second dispensing portions 125, 145 that are foldably connected. As in the previous embodiments, the first dispensing portion 125 contains a first subset of articles P and the second dispensing portion 145 contains a second subset of articles to be dispensed from the carton 105. As shown in Fig. 8, the dispensing portions 125, 145 have an open top for grasping of articles P from the carton 106 and a profile formed by the dispenser 107 that facilitates access to the articles. In the illustrated embodiment, the first and second dispensing portions 125, 145 are adjacent each other and are foldably attached at fold line 173. Alternatively, the dispensing portions 125, 145 could be separated (e.g., the fold line 173 could be replaced with a tear line) without departing from the scope of the invention.
Fig. 9 shows a multi-ply blank 210 according to a second embodiment of the invention. The second embodiment is like the prior embodiment, except for variations noted and variations that will be apparent to those of ordinary skill in the art. For example, the blank 210 is formed into a shipping and dispensing carton 300 (Figs. 10-12) in a similar manner as the previous embodiment. The carton 300 includes a dispenser 207 having a removable dispenser panel 211 forming a dispenser opening 213. In the illustrated embodiment, the dispenser panel 211 comprises a portion of the second side panel 240, the bottom panel 230, and the second top panel 250. The blank 210 includes a line of separation 268 (broadly "dispensing feature") that includes a longitudinal tear line 241 in the second top panel 260, a longitudinal tear line 243 in the bottom panel 230, and a longitudinal tear line 248 in the third top panel 270. The line of separation 268 includes a dispenser tear line 246 in the bottom panel 230, the second side panel 240, and the first top panel 250. A longitudinal fold line 273 in the first side panel 220 connects 1be tear lines 241, 243. The carton 300 is converted from the shipping carton to the dispensing carton having the two foldably attached dispensing portion 225, 245 (Fig. 12) in a similar manner as the previous embodiment.
Fig. 13 shows a blank 305 for a second reference example. In accordance with this reference example, the blank 305 is a single ply. Nonetheless, the blank 305 is formed into a shipping and dispersing carton 400 (Figs. 14-16) in a similar manner as the previous embodiment, In this embodiment, the line of separation 368 comprises a tear strip that includes a first portion 323 in the top panel 330 and the first side panel 340 of the blank 305, and a second portion 325 in the bottom panel 310. Each of the first and second portions 323, 325 of the tear strip 368 extends generally in the longitudinal direction and is formed by respective spaced-apart, longitudinally extending tear lines 375, 377. The first portion 323 extends longitudinally from the lateral fold line 341 across the top panel 330 and the first side panel 320, and across an adhesive panel 360 adjacent to the first side panel to the edge of the blank 305. The second portion 325 of the tear line 368 extends from the lateral fold line 351 across the bottom panel 350 to the edge of the blank 305. A longitudinal fold line 327 connect the first portion 323 to the second portion 325 of the tear line 368.
The carton 400 includes two dispensers 307, 309. In the illustrated embodiment, the two dispensers 307 include identical components and are arranged to be a mirror image of each other, thus common references numerals are used to indicate common components of the dispensers. Each dispenser 307 includes a dispenser panel, generally indicated at 372, removably attached to the blank 1 at a tear line, generally indicated at 374. When the dispenser panel 372 is removed from the carton 400, a dispenser opening 375 (Figs. 15 and 16) is exposed to allow the containers C to be selectively dispensed from the carton. In the illustrated embodiment, the dispenser panel 372 includes a first portion 376 in the top panel 330 of the blank 1, a second portion 378 in the first side panel 320, and a third portion 380 in the second side panel 340. The dispenser panel 372 includes a foldable flap 381 fofdably attached to the third portion 380 at a lateral fold line 383. Each dispenser 307 includes an access opening 385 in the first side panel 320 for grasping the flap 381 to initiate removal of the dispenser panel 372 from the carton 400.
In the illustrated reference example, the tear line 374 includes a first portion 384 extending in the lateral direction in the side panel 320 from the access opening 385 to a curved second portion 386. The second portion 386 extends from the first portion 384 to the longitudinal fold line 331. The tear line 374 includes a third portion 390 extending laterally in the top panel 330 between the longitudinal fold line 331 and the longitudinal fold line 341. A fourth portion 392 of the tear line 374 extends from the intersection of the third portion 390 with the longitudinal fold line 341. The fourth portion 392 of the tear line 374 is curved and extends down from the longitudinal fold line 341 into the side panel 340 and extends upward to the fold line. In the illustrated reference example, the fourth portion 392 is generally semicircular in shape but it is understood that it may be otherwise shaped. The tear line 374 includes a fifth portion 394 extending generally in the lateral direction in the top panel 330 between the intersection of the fourth portion 392 with the longitudinal fold line 341 to the access opening 385 in the side panel 320. In the illustrated reference example the fifth portion 394 of the tear line 374 is generally parallel to the fourth portion, but the tear line may be otherwise sized and shaped.
In the illustrated reference example, the dispensers 307 each include a hinge, generally designated 405 that allows the dispenser opening 375 of each dispenser to be expanded to facilitate access to the container in the carton 400. Each side end flap 322,342 of the blank 305 includes a respective longitudinal fold line 409, 412 parallel to the longitudinal fold lines 365, 366. The hinge 405 includes a first curved tear line 411 that extends from the second portion 386 of the tear line 374 in the first side panel 320, across the lateral fold line 365, 366 and across the longitudinal fold line 409 in the end flap 322. A second curved tear line 413 extends from the fourth portion 392 of the tear line 374 in the second side panel 340, across the lateral fold line 365, 366 and across the longitudinal fold line 412 in the end flap 342. The first and second curved tear lines 411, 413, respective portions of the second and fourth portions 386, 392 of the tear line 374, and the third portion 390 of the tear line define a pivotable flap 415 of the carton 400.

Articles or containers P may be removed from the carton 900 through the dispenser opening 819. Alternatively, the dispenser panel 825 may remain foldably attached to the carton 900 by only partially tearing the dispenser panel 825 along tear line 823.
The blanks according to the present invention can be, for example, formed from coated paperboard and similar materials. For example, the interior and/or exterior sides of the blank can be coated with a clay coating. The clay coating may then be printed over with product, advertising, price coding, and other information or images. The blank may then be coated with a varnish to protect any information printed on the blank. The blank may also be coated with, for example, a moisture barrier layer, on either or both sides of the blank. In accordance with the above-described embodiments, the blank may be constructed of paperboard of a caliper such that it is heavier and more rigid than ordinary paper. The blank can also be constructed of other materials, such as cardboard, hard paper, or any other material having properties suitable for enabling the carton to function at least generally as described herein. The blank can also be laminated or coated with one or more sheet-like materials at selected panels or panel sections.
In accordance with the above-described embodiments of the present invention, a fold line can be any substantially linear, although not necessarily straight, form of weakening that facilitates folding therealong. More specifically, but not for the purpose of narrowing the scope of the present invention, fold lines can include: a score line, such as lines formed with a blunt scoring knife, or the like, which creates a crushed portion in the material along the desired line of weakness; a cut that extends partially into a material along the desired line of weakness, and/or a series of cuts that extend partially into and/or completely through the material along the desired line of weakness; and various combinations of these features.
As an example, a tear line can include: a slit that extends partially into the material along the desired line of weakness, and/or a series of spaced apart slits that extend partially into and/or completely through the material along the desired line of weakness, or various combinations of these features. As a more specific example, one type tear line is in the form of a series of spaced apart slits that extend completely through the material, with adjacent slits being spaced apart slightly so that a nick (e.g., a small somewhat bridging-like piece of the material) is defined between the adjacent slits for typically temporarily connecting the material across the tear line. The nicks are broken during tearing along the tear line. The nicks typically are a relatively small percentage of the tear line, and alternatively the nicks can be omitted from or torn in a tear line such that the tear line is a continuous cut line. That is, it is within the scope of the present invention for each of the tear lines to be replaced with a continuous slit, or the like. For example, a cut line can be a continuous slit or could be wider than a slit without departing from the present invention.
The above embodiments may be described as having one or more panels adhered together by glue during erection of the carton embodiments. The term "glue" is intended to encompass all manner of adhesives commonly used to secure carton panels in place.
The foregoing description of the invention illustrates and describes various embodiments of the present invention. As various changes could be made in the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. Furthermore, the scope of the present covers various modifications, combinations, alterations of the above-described embodiments that are within the scope of the claims.
