BACKGROUND OF THE DISCLOSURE
[0001] The present disclosure generally relates to reinforced packages for holding products and to methods of forming the packages. More specifically, the present disclosure is directed to a package including a bag or liner attached to a carton or blank having features to reinforce the shape of the formed package and allow access to the contents of the package, and features that facilitate forming the package and keeping the package open.
[0002] Bags or liners, such as paper or plastic bags, traditionally have been used for the packaging and transport of products from bulk materials such as rice or sand to larger items. Bags or liners generally are inexpensive and easy to manufacture and can be formed in different configurations and sizes, and can be used for storage and transport of a wide variety of products. In particular, in the food service industry, bags or liners are frequently used for packaging of prepared food items, such as sandwiches, French fries, cereal, etc. Currently, there is a growing demand for bags or liners or similar packages for use in packaging various products, including sandwiches, French fries, cereal, and other prepared food items, for presentation to consumers. However, it is equally important that the costs of such packages necessarily must be minimized as much as possible. While various packages designs including reinforcing or supporting materials have been developed, often, the manufacture of such specialty bags or liners having reinforcing layers or materials supplied thereto has required multiple stages or operations, which can significantly increase the cost of manufacture of such packages.
[0003] US 2015/083789 already shows a reinforced package as per the preamble of claim 1 and a combination of a carton blank and a bag for forming a reinforced package as per the preamble of claim 17 which, however, still leave room for improvement.

DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS
[0011] The present disclosure generally relates to a reinforced package for holding products such as food products or other articles. Packages according to the present disclosure can accommodate articles of any shape. The packages can comprises a bag, liner, or wrap material comprising a relatively flexible material attached to a reinforcing construct comprising a relatively rigid material (e.g., paperboard). The bags or liners can generally be made from a paper, plastic or other stock material and can be attached to the reinforcing construct. In one embodiment, the liners comprise polyethylene material or any other suitable heat-sealable material. The reinforcing construct can be of varying widths and can extend about or over the closed ends of the bags, in some embodiments enclosing such closed ends, and will provide support for the bags upon loading with a product or article or series of articles therein. In some embodiments, the reinforcing construct can be folded with their bags into a configuration supporting the bags in a freestanding, upright and opened condition for ease of loading and ease of use.
[0012] Fig. 1 illustrates a blank 10 for forming a reinforced package generally indicated at 1 (Figs. 4 and 5), that includes a bag 3 attached to a carton 5 according to one embodiment of the disclosure. The bag 3 has an open top end 7 (Fig. 4), a closed or sealed bottom end 9 (Fig. 3), and an interior space 17 (Fig. 4) for holding a product. In one embodiment, the bag 3 has sealed sides 19 (Figs. 3-5) extending the length of the bag between the top 7 and bottom 9. The reinforcing carton 5 has a bottom 20 that supports the sealed bottom 9 of the bag 3. The carton 5 has other features as further described herein to reinforce the package 1 by increasing the rigidity of the package 1 and to lock the package in the formed state of Figs. 4 and 5. The carton 5 can facilitate forming the package 1 and keeping the package 1 open to allow access to the contents in the interior space 17 of the bag 3. Further, the bottom 20 of the carton 5 has support features for allowing the package 1 to be positioned in the upright position of Figs. 4 and 5.
[0013] As shown in Fig. 1, the blank 10 has a lateral axis L1 and a longitudinal axis L2. In the illustrated embodiment, the blank 10 has a front panel 21 foldably connected to a first side panel 28 at a first fold line 33. The first side panel 28 includes two individual panel portions 28a, 28b foldably connected to one another at lateral fold line 26. A first back panel 23 is foldably connected to the first side panel 28 at a second fold line 31. A second side panel 29 is foldably connected to the front panel 21 at a third fold line 35. The second side panel 29 includes two individual panel portions 29a, 29b foldably connected to one another at lateral fold line 27. An attachment flap or second back panel 25 is foldably connected to the second side panel 29 at a fourth fold line 37. In the illustrated embodiment, the blank 10 includes a first bottom end flap or bottom panel 41 foldably connected to the front panel 21 at a longitudinal fold line 43 and a second bottom end flap 45 foldably connected to the first back panel 23 at a longitudinal fold line 47. In the illustrated embodiment, the first bottom end flap 41 includes a longitudinal fold line 49 (e.g., bottom fold line) extending across the width of the bottom end flap 41. Any of the front panel 21, the back panels 23, 25, the side panels 28, 29, the bottom end flaps 41, 45 could be omitted or could be otherwise arranged, shaped, positioned, and/or configured without departing from the disclosure.
[0014] In one embodiment, the panel portions 28a, 28b of the first side panel 28 include a longitudinal fold line 51 extending between respective V-shaped fold lines 32a, 32b that abut the respective fold lines 31, 33. As shown in Figs. 1 and 1A, the longitudinal fold line 51 extends from the vertex of the V-shaped fold line 32a to the vertex of the V-shaped fold line 32b and intersects with the lateral fold line 26. In the illustrated embodiment, the panel portions 29a, 29b of the second side panel 29 include a longitudinal fold line 53 extending between respective V-shaped fold lines 34a, 34b that abut the respective fold lines 35, 37. As shown in Fig. 1, the longitudinal fold line 51 extends from the vertex of the V-shaped fold line 34a to the vertex of the V-shaped fold line 34b and intersects with the lateral fold line 27. In one embodiment, each of the fold lines 31, 33, 35, 37 can be cut-crease style fold lines or any other suitable fold line. As shown in Figs. 1 and 1A, the fold line 31 can include an arcuate cut portion 31a and two oblique portions 31b, 31c extending from the arcuate cut portion 31a to the respective top edge of the blank 10 and bottom flap 45. Similarly, the fold line 33 can include an arcuate cut portion 33a and two oblique portions 33b, 33c, the fold line 35 can include an arcuate cut portion 35a and two oblique portions 35b, 35c, and the fold line 37 can include an arcuate cut portion 37a and two oblique portions 37b, 37c. Alternatively, the arcuate cut portions could be other suitable features (e.g., arcuate creases and/or alternatively shaped) without departing from the disclosure.
[0015] As shown in Fig. 1A, the V-shaped fold line 32a can include a vertex 52 and two spaced ends 54, 56 opposite to the vertex 52. In one embodiment, the vertex 52 can be spaced apart from the lateral fold line 26 by a distance D1 (e.g., a longitudinal distance), the ends 54, 56 can be spaced apart from one another by a distance D2 (e.g., a lateral distance), and each of the ends 54, 56 can be spaced apart from the vertex 52 by a distance D3 (e.g., an oblique distance). Stated another way, the distance D3 is the length of each of the sides of the V-shaped fold line 32a. In the illustrated embodiment, the sides of the V-shaped fold line 52 can extend at an angle A with respect to one another. In one exemplary embodiment, one or both of the distances D2, D3 can be less than the distance D1 (e.g., the distances D2, D3 could be less than or approximately equal to half the distance D1 in one example) so that the V-shaped fold line 32a is relatively small compared to the remainder of the panel portion 28a. Also, in an exemplary embodiment, the angle A could be approximately 60 degrees. Alternatively, the distances D1, D2, D3 could have any suitable relative dimensions and/or the angle A could be any suitable angle. As shown in Fig. 1A, the end 54 of the V-shaped fold line 32a can intersect with the respective ends of the arcuate cut portion 31a and the oblique portion 31b of the fold line 31, and the V-shaped fold line 32a could be continuous with the oblique portion 31b so that the end 54 could be considered a corner in one embodiment. Similarly, as shown in Fig. 1A, the end 56 of the V-shaped fold line 32a can intersect with the respective ends of the arcuate cut portion 31a and the oblique portion 31c of the fold line 31, and the V-shaped fold line 32a could be continuous with the oblique portion 31c so that the end 56 could be considered a corner in one embodiment. In the illustrated embodiment, the other V-shaped fold lines 32b, 34a, 34b are similarly configured to the V-shaped fold line 32a.
[0016] In one embodiment, the fold lines 26, 27, 31, 32a, 32b, 33, 34a, 34b, 35, 37, 51, and 53 comprise strengthening features of the blank that strengthen and reinforce the package 1 formed from the blank by increasing the rigidity of the sides of the carton 5. For example, in one embodiment, the strengthening features can help retain the package in the erected or expanded configuration shown in Figs. 4 and 5 as described in more detail below. Any of the fold lines 26, 27, 31, 32a, 32b, 33, 34a, 34b, 35, 37, 51, 53 and the side panels 28, 29 could be omitted and/or could be otherwise arranged, shaped, positioned, and/or configured without departing from the disclosure.
[0017] In one embodiment, each of the panel portions 28a, 28b of the side panel 28 includes a lower edge having a support or extension 55 adjacent a respective fold line 31, 33 and an oblique edge 57 extending from the support to the lateral fold line 26. Similarly, the panel portions 29a, 29b of the side panel 29 each have a support or extension 65 and oblique edges 67. The front panel 21 has a support or extension 71 defined by a cut 73 that extends between respective ends of the fold line 43. Similarly, the first back panel 23 has a support or extension 75 that is defined by a cut 77 that extends between respective ends of the fold line 47. As shown in Figs. 4 and 5, the supports 55, 65, 71, 75 form the bottom 20 of the carton 5 that supports the formed package 1 on a surface in an upright position such that the open top end 7 of the bag 3 is accessible to provide access to the interior 17 of the bag.
[0018] In one embodiment, the bag 3 (Figs. 3-5) can be formed from similar methods and have similar features as the bag shown in U.S. Provisional Patent Application No. 62/231,723 filed July 14, 2015, and U.S. Patent Application No. 15/209,013 filed July 13, 2016. The bag 3 can be formed by a portion of suitable material 80 shown in Fig. 2 that has a central fold 82 and two outer folds 84 that form the gusseted bottom 9 of the bag 3. In addition, the portion 80 of bag material can have two edge margins 86 extending along the length of the portion 80 as indicated by the dashed lines in Fig. 2. When the gusseted bottom 9 of the bag 3 is formed, the central fold 82 and the two outer folds 84 form four layers of overlapped material at the bottom of the bag such that the bottom of the bag is expandable to accommodate various sizes of product to be held in the bag when the carton 5 is formed to the erected position of the package 1. The portion 80 of bag material is folded at the central fold 82 and outer folds 84 and the overlapping portion s of the edge margins 86 can be sealed together (e.g., heat sealed or otherwise secured together) to form the sealed sides 19 that extend into the bottom 9 of the bag so that the side portions of the overlapped layers of material in the bag 3 are sealed. In the flat configuration of the bag 3 (Fig. 3), the outer folds 84 form the lowermost edge of the bag. In one embodiment, the material for forming the bags 3 can include preprinted paper, polyethylene or other material including flexible and heat-sealable materials. The bag 3 could be otherwise shaped, arranged, and/or configured without departing from the disclosure. Further, the bag 3 could be otherwise formed without departing from the disclosure.
[0019] In one embodiment, the reinforced package 1 can be formed by similar systems and methods as shown in one or more of the patent applications cited herein, wherein the packaging system attaches a web of material for forming the bags 3 of the packages 1 to the blanks 10, and the blanks and web move through a respective packaging system and are formed into the individual packages by various portions and components of the system. The blanks 10 are formed into the reinforced cartons 5 and the web of material is formed into the bags 3, with respective portions 80 of the web of material being overlapped to form the bags. The reinforced packages 1 include the reinforced carton 5 having a bag 3 attached.
[0020] In one embodiment, the separated individual blanks 10 and attached bags 3 are conveyed in the system to a folder/gluer carton forming assembly that includes a series of folders that position the various flaps and panels of the blank 10 to form the flat cartons 5 that can be packaged and shipped for filling with product. In the illustrated embodiment, the bag 3 can be attached to the front panel 21 of the blank 10 (e.g., at glue areas G in the front panel 21) as shown in Fig. 3. The blank 10 can be folded along the lateral fold lines 26, 27 so that the back panel 23 and the attachment flap 25 at least partially overlap the bag 3 and the front panel 21. In addition, the side portions 28a, 29a can overlap the side portions 28b, 29b in the respective side panels 28, 29. In one embodiment, the bag 3 can be glued to the back panel 23 and the attachment flap 25 (e.g., by glue areas G in the respective back panel 23 and attachment flap 25). Accordingly, the bag 3 can be attached to front panel 21, the back panel 23, and the attachment flap 25 of the carton 5. In the illustrated embodiment, the attachment flap 25 can be overlapped with the back panel 23 and adhesively attached thereto. Also, the first bottom end flap 41 can be folded along the longitudinal fold line 49 to overlap the second bottom end flap 45 and the bottom end flaps 41, 45 can be adhesively attached together to form the closed bottom 20 of the carton. The package 1 could be otherwise formed without departing from the disclosure.
[0021] In the illustrated embodiment, the package 1 can be positioned to the erected configuration shown in Figs. 4 and 5 by grasping the side panels 28, 29 and pushing the sides inward at fold lines 26, 27, causing the front panel 21 and back panel 23 to separate or move away from each other to give the package its three dimensional shape and form the interior space 17 of the bag 3 for holding a product. In the erect configuration of the package 1, the supports 55, 65, 71, 75 form the lowermost portion of the bottom 20 of the carton 5 so that the package 1 can be supported on a flat surface and positioned upright in the erect configuration to allow access to the interior space 17 through the top 7 of the bag 3 (Fig. 4). In one exemplary embodiment, the sealed bottom 9 of the bag 3 can be a watertight seal that allows a user to add water or milk to the interior 17 of the bag of the reinforced package 1 to combine with a food product (e.g., cereal, oatmeal, etc.) in the interior. The package 1 can be placed in a microwave oven to heat the food product without departing from the disclosure. Further, the package 1 can be used to hold other types of food products without departing from the disclosure. In the flat configuration of the package 1, the carton 5 is folded flat by folding the side panels 28, 29 along fold lines 26, 27 and folding the bottom 20 at fold line 49 in the first bottom end flap 41.
[0022] In one embodiment, the fold lines 51, 26 in the side panel 28 and the fold lines 53, 27 in the side panel 29 can help increase the rigidity of the formed package 1. Also, the fold lines 26, 27, 31, 33, 35, 37, 51, 53 and the V-shaped fold lines 32a, 32b, 34a, 34b can be configured to allow the side panels 28, 29 to shape open and remain open. Stated another way, the fold lines 26, 31, 33, 51 and the V-shaped fold lines 32a, 32b of the first side panel 28 and the fold lines 27, 35, 37, and the V-shaped fold lines 34a, 34b of the second side panel 29 can help the side panels 28, 29 deform and/or fold inwardly according to a predetermined shape that helps retain the carton 5 in the expanded configuration by resisting forces that would tend to push the panels 28, 29 outwardly and collapse the carton 5. As shown in Figs. 4 and 5, each of the side panels 28, 29 can include an upper portion that extends upwardly and outwardly (e.g., away from the interior of the carton 5) from the respective longitudinal fold lines 51, 52 and the respective V-shaped fold lines 32a, 32b and 34a, 34b. Accordingly, the side panels 28, 29 can bow inwardly (e.g., at least at the longitudinal fold lines 51, 52) to reinforce the structure of the carton 5 so that the package 1 is urged to stay in the erected configuration once formed.
[0023] In the illustrated embodiment, the V-shaped fold lines 32a, 32b, 34a, 34b are aligned with the respective arcuate cut portions 31a, 33a, 37a, 35a at the edges of the side panels 28, 29. The cut portions 31a, 33a, 35a, 37a and V-shaped fold lines 32a, 32b, 34b, 34a can help to create a relief tension in the side panels 28, 29 that facilitates positioning the package 1 in the open position and resists movement of the side panels 28, 29 from the open position of the package 1 when pressure is applied to the package. As shown in Figs.4 and 5, when the package 1 is formed, the arcuate cut portions 31a, 33a, 35a, 37a can form openings in the carton 5 when the side panels 28, 29 are positioned relative to the front panel 21 and back panel 23. The package 1, carton 5, blank 10, and/or bag 3 could have other features, or be otherwise shaped, arranged, and/or configured without departing from the disclosure.
[0024] Fig. 6 is a plan view of a blank 110 for forming a construct 105 (Figs. 8 and 9) of a second embodiment of the disclosure. The second embodiment is generally similar to the first embodiment, except for variations noted and variations that will be apparent to one of ordinary skill in the art. Accordingly, similar or identical features of the embodiments have been given like or similar reference numbers. As shown in Fig. 6, the blank 110 is similar to the blank 10 of the first embodiment except that the V-shaped fold lines 132a, 132b, 134a, 134b of the side panels 128, 129 of the second embodiment are larger than the V-shaped fold lines 32a, 32b, 34a, 34b in the side panels 28, 29 of the first embodiment (as shown in Figs. 1 and 1A). Accordingly, the longitudinal fold lines 151, 153 extending between the respective V-shaped fold lines 132a, 132b and 134a, 134b in the side panels 128, 129 of the blank 110 are shorter than the fold lines 51, 53 of the blank 10 of the first embodiment. In addition, the fold line 131 can have a larger arcuate cut portion 131a and shorter oblique portions 131b, 131c in the second embodiment. Similarly, the fold line 133 can have a lager arcuate cut portion 133a and shorter oblique portions 133b, 133c in the second embodiment, the fold line 135 can have a lager arcuate cut portion 135a and shorter oblique portions 135b, 135c in the second embodiment, and the fold line 137 can have a lager arcuate cut portion 137a and shorter oblique portions 137b, 137c in the second embodiment.
[0025] As shown in Fig. 6A, the vertex 152 of the V-shaped fold line 132a can be spaced from the lateral fold line 26 by a distance D1' (e.g., a longitudinal distance), the ends 154, 156 of the V-shaped fold line 132a can be spaced from one another by a distance D2' (e.g., a lateral distance), and each of the ends 154, 156 can be spaced apart from the vertex 152 by a distance D3' (e.g., an oblique distance). In addition, the sides of the V-shaped fold line can extend at an angle A with respect to one another. In the illustrated embodiment, the V-shaped fold line 132a can be configured similarly to the V-shaped fold line 32a of the first embodiment, except that the distance D3' is larger than the distance D1' (e.g., the distance D3' could be at least twice as long as the distance Dl') so that the V-shaped fold line 132a is relatively large compared to the overall width of the panel portion 28a. In one embodiment, the distance D2' can be similar to the distance D3'. In an exemplary embodiment, the angle A could be approximately 60 degrees. Alternatively, the distances Dl', D2', D3' could have any suitable relative dimensions and/or the angle A could be any suitable angle. The other V-shaped fold lines 132b, 134a, 134b are similarly configured to the V-shaped fold line 132a in the illustrated embodiment. Any of the V-shaped fold lines 132a, 132b, 134a, 134b and the fold lines 26, 27, 131, 133, 135, 137, 151, 153 could be otherwise shaped, arranged, and/or configured without departing from the disclosure.
[0026] As shown in Fig. 6, the supports 55, 57 of the side panels 28, 29 of the first embodiment are omitted in the second embodiment. The side panels 128, 129 can have longitudinal support edges 155, 165, respectively. In one embodiment, the support edges 155, 165 can generally line up with the supports 71, 75 to help support the package 101 in the erect configuration (Figs. 8 and 9). The side panels 128, 129, including the support edges 155, 165, could be otherwise shaped, arranged, and/or configured without departing from the disclosure.
[0027] As shown in Fig. 7, the bag 3 can be glued to the blank 110 with glue areas G in a similar manner as described in the first embodiment. However, in the second embodiment, the bag 3 can at least partially overlap all of the V-shaped fold lines 132a, 132b, 134a, 134b before the blank 110 is folded to form the carton 105. In contrast, the bag 3 is spaced from the V-shaped fold lines 32a, 34a in the first embodiment (Fig. 3).
[0028] The erected package 110 with the bag 3 and the carton 105 is shown in Figs. 8 and 9. As shown in Figs. 8 and 9, in one embodiment, the side panels 128, 129 can partially separate from the front panel 21 and the respective back panels 23, 25 along the arcuate cut portions 133a, 135a, 131a, 137a to form respective openings 190. The package 101, including the carton 105 and the bag 3, could be otherwise shaped, arranged, and/or configured without departing from the disclosure.
[0029] Fig. 10 is a plan view of a blank 210 for forming a construct 205 (Figs. 11 and 12) of a third embodiment of the disclosure. The third embodiment is generally similar to the previous embodiments, except for variations noted and variations that will be apparent to one of ordinary skill in the art. Accordingly, similar or identical features of the embodiments have been given like or similar reference numbers. As shown in Fig. 10, the fold lines 231, 233, 235, 237 have respective cut portions 231a, 233a, 235a, 237a that generally extend in the lateral direction L1 of the blank 210 between the respective oblique portions 231b, 231c; 233b, 233c; 235b, 235c; 237b, 237c. The blank 210 and/or the carton 205 could have other features or the features shown could be otherwise shaped and/or arranged without departing from the disclosure.
[0030] Any of the features of the various embodiments of the disclosure can be combined with, replaced by, or otherwise configured with other features of other embodiments of the disclosure without departing from the scope of this disclosure.
[0031] Generally, as described herein, liners or bags can be formed from a paper stock material, although various plastic or other liner materials also can be used, and can be lined or coated with a desired material. The constructs, blanks, and/or reinforcing sleeves described herein can be made from a more rigid material such as a clay-coated natural kraft ("CCNK"). Other materials such various card-stock, paper, plastic or other synthetic or natural materials also can be used to form the components of the packages described herein.
[0032] In general, the blanks of the present disclosure may be constructed from paperboard having a caliper so that it is heavier and more rigid than ordinary paper. The blank can also be constructed of other materials, such as cardboard, or any other material having properties suitable for enabling the carton to function at least generally as described above. The blank can be coated with, for example, a clay coating. The clay coating may then be printed over with product, advertising, and other information or images. The blanks may then be coated with a varnish to protect information printed on the blanks. The blanks may also be coated with, for example, a moisture barrier layer, on either or both sides of the blanks. The blanks can also be laminated to or coated with one or more sheet-like materials at selected panels or panel sections.
[0033] 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 disclosure 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 disclosure.
[0034] In accordance with the exemplary embodiments, a fold line can be any substantially linear, although not necessarily straight, form of weakening that facilitates folding there along. More specifically, but not for the purpose of narrowing the scope of the present disclosure, fold lines include: a score line, such as lines formed with a blunt scoring knife, or the like, which creates a crushed or depressed 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. In situations where cutting is used to create a fold line, typically the cutting will not be overly extensive in a manner that might cause a reasonable user to incorrectly consider the fold line to be a tear line.
[0035] 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.
[0036] The foregoing description of the disclosure illustrates and describes various embodiments. As various changes could be made in the above construction without departing from the scope of the disclosure, 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.
