DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

The present disclosure generally relates to cartons and packages for holding products or articles such as food products or other articles. Packages according to the present disclosure can accommodate articles of any shape. For purpose of illustration and not for the purpose of limiting the scope of the disclosure, the terms “lower”, “bottom”, “upper”, “top”, “front”, and “back” indicate orientations determined in relation to erected cartons.

FIG. 1 is a plan view of an interior surface 1 of a carton blank 3 for forming a reinforcing carton 5 (FIG. 5) for holding a bag 6 or liner in a reinforced package 200 (FIG. 14), according to an embodiment of the disclosure. The carton blank 3 has a lateral axis L1 and a longitudinal axis L2. In the illustrated embodiment, the carton blank 3 has a front panel 21 foldably connected to a first side panel 28 at a first fold line 33, a back panel 23 foldably connected to the first side panel 28 at a second fold line 37, and a second side panel 29 foldably connected to the front panel 21 at a third fold line 40. As shown in FIG. 1, an attachment flap 25 is foldably connected to the second side panel 29 at a fourth fold line 43.

As shown in FIG. 1, the first side panel 28 includes two individual panel portions 28a, 28b foldably connected to one another along a lateral fold line 26. Similarly, the second side panel 29 includes two individual panel portions 29a, 29b foldably connected to one another along a lateral fold line 27.

In the illustrated embodiment, the first fold line 33 is segmented into two oblique fold line segments 34, 35 extending from a vertex 30a. The second fold line 37 is segmented into two oblique fold line segments 38, 39 extending from a vertex 30b. The third fold line 40 is segmented into two oblique fold line segments 41, 42 extending from a vertex 31a. The fourth fold line 43 is segmented into two oblique fold line segments 44, 45 extending from a vertex 31b. The fold lines 33, 37 can be spaced apart from lateral fold line 26 so that the vertices 30a, 30b are spaced apart from the lateral fold line 26 farther than the opposite ends of the oblique fold line segments 34, 35, 38, 39 (e.g., the panel portions 28a, 28b and the first side panel 28 are widest between or adjacent the vertices 30a, 30b). Similarly, the fold lines 40, 43 are spaced apart from lateral fold line 27 so that the vertices 31a, 31b are spaced apart from the lateral fold line 27 farther than the opposite ends of the oblique fold line segments 41, 42, 44, 48 (e.g., the panel portions 29a, 29b and the first side panel 29 are widest between or adjacent the vertices 31a, 31b). The fold lines 33, 37, 40, 43 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.

As shown in FIG. 1, the blank 3 further can include a first bottom panel 51 foldably connected to the back panel 23 at longitudinal fold line 71 and a second bottom panel 52 foldably connected to the front panel 21 at longitudinal fold line 72. As illustrated, a bottom end flap 53 is foldably connected to the second bottom panel 52 at fold lines 57. A locking tab 55 extends from the second bottom panel 52 and is separable from the bottom end flap 53 along a cut 58. Furthermore, a complementary locking notch or recess 54 is formed in the first bottom panel 51 and defines an edge of the first bottom panel 51 for engaging the locking tab 55. The locking notch 54 is sized or dimensioned to engage the locking tab 55.

In the illustrated embodiment, the blank 3 includes adhesive regions 60 on the back panel 23, and front panel 21, for receiving adhesive and being fixedly attached to an exterior surface of the bag 6. Additionally, the blank 3 can include an adhesive region 61 on the attachment flap 25 for receiving adhesive and being fixedly attached to an interior surface of the back panel 23. The adhesive regions 60, 61 could be omitted or could be otherwise arranged, shaped, positioned, and/or configured without departing from the disclosure.

As shown in FIG. 1, the carton blank 3 has a first edge 70 (e.g. free edge) generally extending in the longitudinal direction L2. The blank 3 further includes oblique edges 73, 74, 75, and 76 (e.g. free edges) arranged opposite the first edge 70. Accordingly, the edges 73, 74, 75, 76 form lower free edges of the respective panel portions 28b, 28a, 29a, 29b. The edges 70, 73, 74, 75, 76 could be omitted or could be otherwise arranged, shaped, positioned, and/or configured without departing from the disclosure.

In the illustrated embodiment, the carton blank 3 and carton 5 can comprise any material which is relatively rigid such as paperboard, clay-coated paperboard, solid bleached board (SBB) paperboard, solid bleached sulphate (SBS) paperboard, Kraft line paperboard, or any other suitable material without departing from the disclosure. In alternative embodiments, the carton blank 3 could be otherwise shaped and could have alternative panel, flap, fold line, and/or panel portion arrangements.

Turning to FIG. 2, a plan view of an interior surface 101 of an insert blank 103 or portion of liner material for forming a bag 6 (FIG. 6) of the reinforced package 200 (FIG. 12) is illustrated. As illustrated in FIG. 2, the lateral axis L1 and the longitudinal axis L2 of the liner blank 103 are oriented so that the lateral axis L1 and the longitudinal axis L2 of the liner blank 103 comport with the respective lateral axis L1 and longitudinal axis L2 of the carton blank 3 established in FIG. 1. The liner blank 103 or liner material may be formed of generally non-permeable material or layers of material, such that a formed bag 6 may hold liquid. The liner blank 103 can comprise any suitable material which is relatively flexible and relatively fluid impervious. The liner blank 103 can comprise plastics such as polyethylene, polypropylene, polyethylene terephthalate, polystyrene, poly vinyl chloride, or any other suitable material without departing from the disclosure. Alternatively, the liner blank 103 could comprise a fluid pervious material without departing from the disclosure.

As shown in FIG. 2, the liner blank 103 may include sidewalls 105, 106 foldably connected to gusset panels 107, 108 at fold lines 109, 110, respectively. The gusset panels 107, 108 may be foldably connected to one another at fold line 113. The liner blank 103 may include glue areas 115, 116 extending along respective marginal areas of the blank and at least partially defined between a respective laterally-extending edge 117, 118 and a respective line 119, 120. In one embodiment, the lines 119, 120 only schematically indicate the inner periphery of the glue areas 115, 116. In an alternative embodiment, the lines 119, 120 are drawn on and/or formed in the liner blank 103. For example, guide lines may be drawn on the liner blank 103 and/or creases may be formed in the liner blank 103. Each of the glue areas 115, 116 can include sealing regions 121, 122 at opposite ends of the respective sidewalls 105, 106 along lateral portions of the lines 119, 120 and sealing corner portions 123, 124 at opposite ends of the respective sidewalls 105, 106 adjacent oblique portions of the respective lines 119, 120 and adjacent the respective fold lines 109, 110. Additionally, the glue areas 115, 116 can include respective sealing corner portions 125 at opposite ends of the gusset panel 107 between fold lines 109, 113 and adjacent an oblique portion of the respective lines 119, 120 and respective sealing corner portions 127 at opposite ends of the gusset panel 108 between fold lines 110, 113 and adjacent an oblique portion of the respective lines 119, 120. The sidewalls 105, 106, the gusset panels 107, 108, and/or the glue areas 115, 116 could be omitted or could be otherwise arranged, shaped, positioned, or configured without departing from the disclosure.

The bag 6 can be formed, in one exemplary embodiment, as shown in FIG. 3. Accordingly, the liner blank 103 can be folded along the fold lines 113, 109, 110 so that the gusset panels 107, 108 are at least partially in face-to-face contact with one another and with the respective sidewalls 105, 106. Additionally, the sidewalls 105, 106 are disposed at least partially in face-to-face contact with one another above the gusset panels 107, 108. Glue can be applied to at least a portion of each of the glue areas 115, 116 (e.g., the shaded regions in FIG. 3) on the interior surface 101 of the liner blank 103 before, after, and/or during folding along the fold lines 109, 110, 113. Accordingly, when the sealing regions 121 of the sidewall 105 are disposed in face-to-face contact with the respective sealing regions 122 of the sidewall 106, the sealing regions are glued together to at least partially form a seam 130 at each end of the bag 6 (FIG. 3). Additionally, each of the sealing corner portions 123 of the sidewall 105 is glued to the respective sealing corner portions 125 of the gusset panel 107 and each of the sealing corner portions 124 of the sidewall 106 is glued to the respective sealing corner portion 127 of the gusset panel 108 to form two sealed corners 132 at the bottom ends of each of the seams 130. The bag 6 could be formed from the liner blank 103 by alternative steps without departing from the disclosure.

In one embodiment, the portions of the sidewalls 105, 106 and the gusset panels 107, 108 outside the glue areas 115, 116 remain generally free of glue so that the sidewalls and gusset panels generally are not glued together outside the glue areas. Accordingly, the bag 6 can be expanded to open up an interior space of the bag by moving the sidewalls 105, 106 apart from one another and by folding the gusset panels 107, 108 along fold lines 109, 110, 113 so that the gusset panels 107, 108 are generally coplanar and extend between the spaced-apart sidewalls 105, 106. The seams 130 and the sealed corners 132 can form closed ends or sides of the bag 6, and the gusset panels 107, 108 and the sealed corners 132 can form a closed bottom 136 of the bag 6 while the bag is in either the collapsed configuration (e.g., FIG. 3) or the opened configuration (e.g., FIG. 17). The bag 6 can be positioned from the opened configuration to the closed configuration by folding the gusset panels 107, 108 inwardly along the fold lines 109, 110, 113 so that the fold line 113 and the gusset panels 107, 108 are disposed between the sidewalls 105, 106. The bag 6 could be positioned or moved between the collapsed configuration and the opened configuration by alternative steps without departing from the disclosure.

Generally, the carton blank 3 may be folded about fold lines 26, 27 to form an open-ended sleeve 134 (e.g., a reinforcing sleeve formation). For example, referring to FIGS. 4-6, the bag 6 can be aligned with the carton blank 3 (FIG. 4) and distal oblique edges 46, 47 of the back panel 23 may be overlapped and/or brought into registration with fold line segments 44, 45 (FIG. 5) such that the back panel 23 at least partially overlaps the attachment flap 25 and adhesive region 61 to form the open-ended sleeve 134 (FIGS. 5 and 6). Accordingly, the back panel 23 can be glued to the attachment flap 25 by the adhesive region 61. During this sequence, the reinforcing sleeve 134 can be attached (e.g., glued) to the bag 6 through adhesive regions 60. For example, the sidewalls 105, 106 can be glued to the respective front panel 21 and back panel 23 at adhesive regions 60. Further, the seams 130 and the outer portions of the sealed corners 132 of the bag 6 may be folded to rest against the sidewall 106 as illustrated in FIG. 5. Alternatively, the seams 130 and the outer portions of the sealed corners 132 of the bag 6 may be folded to rest against the sidewall 105. The bag 6 could be otherwise attached to the carton blank 3/carton 5 without departing from the disclosure. For example, the either of the sidewalls 105, 106 could be glued to either of the front panel 21 and/or back panel 23 prior to folding the carton blank 3 or during or after formation of the carton 5.

Upon attachment of the reinforcing sleeve 134 to the bag 6, bottom panel 51 may be folded inwardly against the bag 6 as illustrated in FIG. 7. Thereafter, bottom panel 52 and bottom end flap 53 may be folded inwardly against the bottom panel 51 such that the locking tab 55 is brought into locking engagement with the locking notch 54, as illustrated in FIGS. 8-10. According to some embodiments, the bottom end flap 53 may receive adhesive and can be fixedly attached to the bottom panel 51. Alternatively, the bottom end flap 53 can remain free from attachment to the bottom panel 51. Furthermore, the folding sequences described above may be altered or omitted in some embodiments, without departing from the scope of the disclosure.

Upon folding the bottom panels 51, 52 and bottom end flap 53, a reinforcing carton 5 exists about the bag 6 forming a reinforced package 200. In one embodiment, the bag 6 is glued to an interior surface of the front panel 21 and/or the back panel 23 in an interior 148 of the carton 5. Accordingly, the closed bottom 136 of the bag 6 can be disposed in the interior 148 of the carton 5. In the illustrated embodiment, the package 200 can be in a first, non-erected position or configuration (FIGS. 11-13) or in a second, erected position or configuration (FIGS. 17-20). In the first position, the individual panel portions 28a, 28b, 29a, and 29b are folded along the respective lateral fold lines 26, 27 so that the panel portions 28a, 29a generally oppose the respective panel portions 28b, 29b. The first, non-erect position illustrated reduces and/or minimizes (e.g., collapses) a volume of an interior space 150 of the bag 6 such that the reinforced package is in a non-erect or semi-flattened state (FIGS. 12A and 13). As shown in FIG. 12B, the carton 5 and bag 6 could be fully or substantially fully flattened in one embodiment. The non-erect state may facilitate easy stacking of a plurality of packages into, for example, a shipment container and subsequent organization at a destination facility. However, as illustrated in FIG. 13, the non-erect state may still facilitate the filling of the interior volume 150 at least partially with a product. Thereafter, the interior volume 150 may be sealed in any feasible manner in one embodiment.

Upon receipt of a reinforced package 200 in the first, non-erect position (with or without a sealed interior volume 150), the individual panel portions 28a, 28b, 29a, and 29b may be flexed or positioned to form first and second sides 28, 29 of the package in a second, erect position of the package as illustrated in FIGS. 14-17. Accordingly, in one embodiment, the side panels 28, 29 are pushed inwardly at the respective fold lines 26, 27. The side panel 28 can be folded along fold lines 26, 33, 37 until the panel portions 28a, 28b are generally coplanar, extending between the front panel 21 and the back panel 23. Similarly, and, in one embodiment, at the same time, the side panel 29 can be folded along fold lines 27, 40, 43 until the panel portions 29a, 29b are generally coplanar, extending between the front panel 21 and the attachment flap 25 and the back panel 23. Additionally, as the front panel 21 and the back panel 23 move away from one another, the bottom panels 51, 52 can fold along fold lines 71, 72 to be generally coplanar, extending between the front panel and the back panel to form a closed bottom of the carton 5. Further, the sidewalls 105, 106 of the bag 6 are glued to the respective front panel 21 and back panel 23, and the bag can be positioned in the open position by the front and back panels as the side panels 28, 29 are moved inwardly.

In one embodiment, since the side panels 28, 29 are widest between the vertices 30a, 30b and 31a, 31b, when the package 200 is in the second, erected position, the side panels 28, 29 can push against the front panel 21 and the back panel 23 at the vertices 30a, 30b and 31a, 31b. This can create tension that can help retain the panel portions 28a, 28b and 29a, 29b in the generally coplanar position (e.g., can help resist folding of the side panels 28, 29). Additionally, since the front panel 21 and the back panel 23 are widest at the edge 70 and at the lower edges (e.g., fold lines 71, 72), the oblique fold line segments 34, 35, 38, 39 and 41, 42, 44, 48 further can help resist folding of the side panels 28, 29. In one embodiment, the side panels 28, 29 can be generally concave from the exterior of the carton 5 because of the oblique fold line segments of the fold lines 33, 37, 40, 43. Accordingly, the oblique fold line segments 34, 35, 38, 39, 41, 42, 44, 48, the vertices 30a, 30b, 31a, 31b and the panel portions 28a, 28b, 29a, 29b can cooperate with one another and with the interlocked bottom panels 51, 52 (including the locking tab 55) to form locking features that can help retain the package 200 in the erected configuration. In one embodiment, for example, the locking features can be at least partially disengaged, by pushing outwardly on one or both of the fold lines 26, 27 and moving the front panel 21 and the back panel 23 toward one another. The package 200 can be reconfigured between the non-erected and erected positions using alternative steps and/or features without departing from the disclosure.

The second, erect position, illustrated in FIG. 17, increases and/or maximizes a volume of the interior space 150 such that the package 200 is in an erect or self-supporting state. Bottom edges 71, 72, 73, 74, 75, 76 can cooperate to form a support when the package 200 is in the erect state for contacting a surface S (e.g., FIG. 17). The support formed of the bottom edges 71, 7273, 74, 75, 76 (e.g., in a locking interaction due to side panels 28, 29) maintains the package in an upright position on the surface S. Furthermore, due to the impermeable nature of the bag 6, a user may fill the interior volume 150 at least partially with a liquid (e.g., water, heated water, etc.) for rehydrating a product within the volume 150. Moreover, according to some embodiments, the entire package 200 (filled with liquid or not) may be heated in a microwave oven to facilitate cooking and/or rehydrating of the contents of the bag 6. Other intervening states of the package 200 including intermediate states whereby the package is not fully erected are also applicable according to some embodiments. Furthermore, automatically erecting reinforced packages 200 are also applicable, for example, if bag 6 is filled with an expanding food product such as popcorn that expands when heated to move the front panel 21 and the back panel 23 apart to at least partially form side panels 28, 29 during the cooking process.

Generally, as described herein, bags can be formed from a bag stock material, although various plastic or other bag materials also can be used, and can be lined or coated with a desired material. The reinforcing cartons 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.

The blank according to the present disclosure 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 above. The blank can also be laminated to 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 disclosure, 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 disclosure, fold lines 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. 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 or other line of disruption.

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.

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.
