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.
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.
In one aspect, the present disclosure is generally directed to a reinforced package comprising a carton comprising a plurality of panels that extend at least partially around an interior of the carton. The plurality of panels can comprise a front panel, a first side panel foldably connected to the front panel, a second side panel foldably connected to the front panel, and at least one back panel foldably connected to at least one of the first side panel and the second side panel. A bag can be attached to the carton. The bag can have an at least partially open end, an at least partially closed end, and an interior space for holding a product. The carton can be positionable in a non-erect position wherein the interior space of the bag is at least partially collapsed and in an erect position wherein the interior space of the bag is increased. The carton can be configured to support the bag in the erect position and the first side panel, and the second side panel can have retention features for at least partially retaining the carton in the erect position.
In one aspect, the present disclosure is generally directed to the combination of a carton blank and a bag for forming a reinforced package for holding a product. The carton blank can be for forming a carton and can comprise a plurality of panels comprising a front panel, a first side panel foldably connected to the front panel, a second side panel foldably connected to the front panel, and at least one back panel foldably connected to at least one of the first side panel and the second side panel. The bag can comprise an at least partially open end, an at least partially closed end, and an interior space for holding a product. The bag can be at least partially attached to the carton blank. The reinforced package formed from the carton blank and the bag can be positionable in a non-erect position wherein the interior space of the bag is at least partially collapsed and in an erect position wherein the interior space of the bag is increased. The first side panel and the second side panel can have retention features for at least partially retaining the carton formed from the carton blank in the erect position.
In one aspect, the present disclosure is generally directed to a method of forming a reinforced package. The method can comprise obtaining a carton blank at least partially attached to a bag.

In the illustrated embodiment, the first fold line 33 is segmented into two oblique fold line segments 33a, 33b extending from a vertex 38a. The second fold line 31 is segmented into two oblique fold line segments 31a, 31b extending from a vertex 38b. The third fold line 35 is segmented into two oblique fold line segments 35a, 35b extending from a vertex 39a. The fourth fold line 37 is segmented into two oblique fold line segments 37a, 37b extending from a vertex 39b. The fold lines 33, 31 can be spaced apart from the lateral fold line 26 so that the vertices 38a, 38b are spaced apart from the lateral fold line 26 farther than the opposite ends of the oblique fold line segments 33a, 33b, 31a, 31b (e.g., the panel portions 28a, 28b and the first side panel 28 are widest between or adjacent the vertices 38a, 38b). Similarly, the fold lines 37, 35 are spaced apart from the lateral fold line 27 so that the vertices 39a, 39b are spaced apart from the lateral fold line 27 farther than the opposite ends of the oblique fold line segments 37a, 37b, 35a, 35b (e.g., the panel portions 29a, 29b and the first side panel 29 are widest between or adjacent the vertices 39a, 39b). The fold lines 33, 31, 37, 35 could be omitted or could be otherwise arranged, shaped, positioned, and/or configured without departing from the disclosure. For example, the fold lines could be arcuate fold lines rather than segmented fold lines as shown.
In one embodiment, the panel portions 28a, 28b of the first side panel 28 can include a longitudinal fold line 51 extending between the fold lines 31, 33. The panel portions 29a, 29b of the second side panel 29 include a longitudinal fold line 53 extending between the fold lines 35, 37. As shown in
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. Stated another way, the two oblique edges 57 meet at an end of the lateral fold line 26 and extend from one another to the respective support 55. Similarly, the panel portions 29a, 29b of the side panel 29 each have a support or extension 65 and oblique edges 67 extending from the support to the lateral fold line 27. Stated another way, the two oblique edges 67 meet at an end of the lateral fold line 27 and extend from one another to the respective support 65. As shown in
In one embodiment, the bag 3 can be formed from similar methods and have similar features as the bag shown in incorporated by reference U.S. Provisional Patent Application No. 62/231,723. The bag can be formed by a portion of suitable material (e.g., a web of material can be folded, sealed, and cut to form the bag). A portion 150 of a web of material is shown schematically in
As shown in
In one embodiment, the reinforced package 1 can be formed by a packaging system that attaches the web of material for forming the bags 3 to respective 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. In another embodiment, the reinforced package 1 can be formed by similar systems and methods as shown in the incorporated by reference U.S. Provisional Patent Application No. 62/231,723, wherein the bags 3 can be at least partially formed and then attached to the respective blanks 10 and the blanks and web can be moved through a respective packaging system and formed into the individual packages by various portions and components of the system. The reinforced package 1 could be otherwise formed without departing from the disclosure.
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 sealed side portions 19 of each bag 3 are formed by bonding (e.g., heat sealing such as by a rotary heat sealer) the overlapped edge margins 119 of the web of material 150. The bags 3 can be attached to the respective blanks 10 by glue. For example, the bag 3 can be attached to the front panel 21 of the blank 3 at glue strips G1. The bag 3 could be otherwise formed and/or attached to the blank 10 without departing from the disclosure.
In one embodiment, the individual blanks 10 with 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 one embodiment, the blank 10 can be folded along lateral fold lines 26, 27 so that the panel portions 28b, 29a at least partially overlap the respective panel portions 28a, 29b and the second back panel 25 is overlapped with the first back panel 23 and adhesively attached thereto. As shown in
As shown in
In the erected configuration of the package 1 (
In one embodiment, the sealed bottom 9 of the bag 3 can be a water-tight 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.
The fold lines 51, 26 in the side panel 28 and the fold lines 53, 27 in the side panel 29 increase the rigidity of the formed package 1. The side panels 28, 29 can fold along the fold lines 51, 26; 53, 27 to bow inward to reinforce the structure of the carton 5 so that the package 1 is urged to stay in the erected configuration once formed. The package 1, carton 5, and/or blank 10 could have other features, or be otherwise shaped, arranged, and/or configured without departing from the disclosure.
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.
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.
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.
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.
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 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.
