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.
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 general, one aspect of the disclosure is directed to a reinforced package comprising a carton comprising a plurality of panels that extends at least partially around an interior of the carton. The plurality of panels can comprise a front panel and a back panel disposed opposite to the front panel. The carton can comprise a bottom wall foldably connected to the front panel along a first curved fold line and to the back panel along a second curved fold line. The reinforced package further can include a bag at least partially attached to the carton. The bag can be at least partially defining 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 at least the bottom wall and the first curved fold line can be configured to retain the carton in the erect position.
In another aspect, the disclosure is generally directed to, in combination, 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 and a back panel, the carton blank comprising a first bottom end flap foldably connected to the front panel along a first curved fold line and a second bottom end flap foldably connected to the back panel along a second curved fold line. The first bottom end flap and the second bottom end flap can at least partially form a bottom wall when the carton is formed from the carton blank. A bag can be at least partially attached to the carton blank, and the bag can at least partially define an interior space for holding a product. The carton formed from the carton blank 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 when the reinforced package is formed from the carton blank and the bag. The carton formed from the carton blank can be configured to support the bag in the erect position when the reinforced package is formed from the carton blank and the bag. At least the bottom wall and the first curved fold line can be configured to retain the carton in the erect position when the reinforced package is formed from the carton blank and the bag.
In another aspect, the disclosure is generally directed to a method of forming a reinforced package for holding a product. The method can comprise obtaining a carton blank comprising a plurality of panels comprising a front panel and a back panel, the carton blank comprising a first bottom end flap foldably connected to the front panel along a first curved fold line and a second bottom end flap foldably connected to the back panel along a second curved fold line. The method further can comprise forming a bag at least partially attached to the carton blank, the bag at least partially defining an interior space for holding a product, and forming an interior of a carton at least partially defined by the plurality of panels with the back panel disposed opposite to the front panel. The forming the interior of the carton can comprise forming a bottom wall comprising the first bottom end flap and the second bottom end flap. 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, and the carton can be configured to support the bag in the erect position. At least the bottom wall and the first curved fold line can be configured to retain the carton in the erect position.

In the illustrated embodiment, the curved fold lines 43, 47 can comprise strengthening or retention features of the blank that strengthen and reinforce the package 1 formed from the blank by increasing the rigidity of the bottom and/or 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
In one embodiment, the bag 3 (
In one embodiment, the reinforced package 1 can be formed by similar systems and methods as shown in one or more of the incorporated by reference patent applications, 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 90 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. In one embodiment, the bags 3 can be partially or fully formed prior to being attached to the carton blanks 10 and/or the bags 3 and/or the cartons 5 could be formed by hand.
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 as shown in

In the erect configuration of the package 1, the carton 5 can rest on the bottom edges 42 of the side panels 28, 29 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 (
In the illustrated embodiment, the package 1 can be moved from the erected configuration to the flattened configuration by folding the bottom panels 41, 45 outwardly along fold lines 43, 47, 49 and pressing the front panel 21 and the back panel 23 inwardly. As the carton 5 collapses, the side panels 28, 29 can fold outwardly along fold lines 26, 30, 31 and 27, 32, 33. The package 1 could be otherwise moved from the erected configuration to the flattened configuration without departing from the disclosure.
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.
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.
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. Furthermore, the scope of the present disclosure covers various modifications, combinations, alterations, etc., of the above-described embodiments. Additionally, the disclosure shows and describes only selected embodiments, but various other combinations, modifications, and environments are within the scope of the disclosure as expressed herein, commensurate with the above teachings, and/or within the skill or knowledge of the relevant art. Furthermore, certain features and characteristics of each embodiment may be selectively interchanged and applied to other illustrated and non-illustrated embodiments of the disclosure.
