The present disclosure generally relates to a carton with dispensing features that may contain products such as flowable materials or food products (e.g., cereal) or any other flowable material (e.g., powder-type mixes, granular materials, salts or other crystallines, detergents, etc.). The carton can include a liner in the carton interior. The liner can be used to protect and store product in the carton. The liner can be made from materials suitable in composition for packaging the particular product, and the materials include, but are not limited to, plastics such as PET, LDPE, LLDPE, HDPE, PP, PS, PVC, EVOH, and Nylon; metals; papers; and the like, or any combination thereof. Alternatively, the liner can be omitted. In one or more embodiments, in this specification, the terms “front,” “back,” “lower,” “bottom,” “upper” and “top” indicate orientations determined in relation to fully erected and upright cartons.
FIG. 1 is a plan view of the exterior side 1 of a blank, generally indicated at 3, used to form a carton 5 (FIG. 7) according to an exemplary first embodiment of the disclosure. The carton 5 can be used to house a flowable material F (e.g., a food product such as cereal as shown in FIG. 4) or other products. The carton 5 can have a top closed end 7 and a bottom closed end 9 (FIG. 7). In the illustrated embodiment, the carton 5 includes a dispenser, generally indicated at 11 (FIGS. 7-9) for dispensing product from within the carton at the top end 7 of the carton. A liner or bag 13 (FIGS. 2-6) can be disposed within the carton 5 to form a package 15 (FIGS. 7-9). In the illustrated embodiment, the bag 13 can include one or more dispenser features 17 for cooperating with the dispenser 11 of the carton 5 (FIGS. 8 and 9).
As shown in FIG. 1, the blank 3 has a longitudinal axis L1 and a lateral axis L2. In the illustrated embodiment, the blank 3 comprises a first end or back panel 21 foldably connected to a first side panel 23 at a first lateral fold line 25, a second end or front panel 27 foldably connected to the first side panel 23 at a second lateral fold line 29, and a second side panel 31 foldably connected to the front panel 27 at a third lateral fold line 33. In the illustrated embodiment, the blank 3 includes an attachment flap 35 foldably connected to the second side panel 31 at a fourth lateral fold line 37. Alternatively, the attachment flap 35 could be foldably connected to the back panel 21 or could be omitted without departing from the disclosure.
In the illustrated embodiment, the back panel 21 is foldably connected to a back top flap 39 and a back bottom flap 41. The first side panel 23 is foldably connected to a first side top flap 43 and a first side bottom flap 45. The front panel 27 is foldably connected to a front top flap 47 and a front bottom flap 49. The second side panel 31 is foldably connected to a second side top flap 51 and a second side bottom flap 53. The top flaps 39, 43, 47, and 51 extend along a first or top marginal area of the blank 3. The back top flap 39 is foldably connected to the back panel 21, the first side top flap 43 is foldably connected to the first side panel 23, the front top flap 47 is foldably connected to the front panel 27, and the second side top flap 51 is foldably connected to the second side panel 31 along a first longitudinal extending fold line 62 that extends along the length of the blank. The bottom flaps 41, 45, 49, 53 extend along a second or bottom marginal area of the blank 3. The bottom flaps 41, 45, 49, 53 are foldably connected to the respective panels 21, 23, 27, 31 along a second longitudinally extending fold line 64 that extends along the length of the blank. In one embodiment, the longitudinal fold lines 62, 64 may be, for example, substantially straight, or offset at one or more locations to account for blank thickness or for other factors. When the carton 5 (FIG. 7) is erected, the top end flaps 39, 43, 47, 51 can at least partially close the top end 7 of the carton 5, and the bottom end flaps 41, 45, 49, 53 can at least partially close the bottom end 9 of the carton 5.
As shown in FIG. 1, the dispenser features that form the dispenser 11 in the illustrated embodiment can include a first dispenser flap 55 and a second dispenser flap 57, which can be foldably connected to the respective first side panel 23 and second side panel 31 along the longitudinal fold line 62. In one embodiment, the first dispenser flap 55 can be separable from the first side top flap 43 along a tear or cut line 59, and the second dispenser flap 57 can be separable from the second side top flap 51 along a cut or tear line 61. The dispenser features can also include a tear strip 63 with a starting tab 65. The tear strip 63 can be defined by two, spaced apart tear lines extending in the first dispenser flap 55. As shown in FIG. 1, the first dispenser flap 55 can include a distal or glue portion 67 between the tear strip 63 and the outer edge of the first dispenser flap 55, and the remainder of the first dispenser flap 55 after removing the tear strip 63 to open the dispenser 11 (FIGS. 8 and 9) forms a reclosable flap 69 with a closing tab 71. As shown in FIG. 1, the second dispenser flap 57 can include a notch 73 for receiving the closing tab 71 when closing the dispenser 11 after removing the tear strip 63.
In the illustrated embodiment, the dispenser 11 can also include features for forming a spout 75 (FIG. 9) when the dispenser 11 is opened. As shown in FIG. 1, the spout features can include a lateral fold line 77a generally bisecting the front top flap 47, two oblique fold lines 77b, 77c extending from an end of the lateral fold line 77a (e.g., at the intersection of the lateral fold line 77a and the longitudinal fold line 62), and a longitudinal fold line 77d extending from the ends of the oblique fold lines 77b, 77c (e.g., at the intersection of the fold lines 77b, 77c and the respective lateral fold lines 29, 33). Accordingly, as shown in FIG. 9, the front panel 27 and/or the front top flap 47 can fold along the fold lines 29, 33, 77a, 77b, 77c, 77d at the spout 75 to generally form a shape that can help direct the flowable material F as it is poured out of the package 15 at the spout 75. Any of the dispenser features, including the dispenser flaps 55, 57 and/or the spout 75, could be omitted or could be otherwise shaped, arranged, positioned, and/or configured, without departing from the disclosure.
As schematically shown in FIG. 2, two or more bags 13 can be formed in series and can have a longitudinal axis L3 and a lateral axis L4. For example, in one embodiment, the bags 13 can be formed in a generally tubular length of material (e.g., plastic or any other suitable material). The tubular material could be formed by folding a sheet of material and securing the marginal portions along the length of the bag together to form a longitudinal seam 79 (FIGS. 3-5). The seam 79 can be secured by gluing, welding (e.g., ultrasonic welding, heat welding, radio frequency welding, etc.), and/or any other suitable method. Each bag 13 can be have a respective bottom seal 81 and a top seal 83, wherein the sidewalls of the bag can be secured together at the respective top and bottom of the bag by gluing, welding (e.g., ultrasonic welding, heat welding, radio frequency welding, etc.), and/or any other suitable method. Additionally, each bag 13 can be separated from the respectively adjacent bags along a cut 85. In one embodiment, the bottom seal 81 of one bag 13, the top seal 83 of an adjacent bag 13, and the cut 85 between the two bags can be formed simultaneously or in a sequence.
As shown in FIGS. 2-5, the top seal 83 of each bag 13 can include a lateral portion 87a and an oblique portion 87b. Accordingly, the oblique portion 87b of the top seal 83 can form the dispenser feature 17 in the bag 13. For example, the oblique portion 87b can form a larger area adjacent one of the top corners of the bag 13 where the sidewalls of the bag are not secured together (e.g., are free from connection to one another) above the top seal 83. When aligned with the dispenser 11 (e.g., FIGS. 8 and 9), the dispenser feature 17 can provide a portion of the bag that is accessible through the dispenser 11 in the carton 5 where a user can easily grasp the sidewalls of the bag to pull the sidewalls apart and at least partially separate the sidewalls from one another along at least the oblique portion 87b of the top seal 83 to at least partially open the bag.
In the illustrated embodiment, each bag 13 can be filled with flowable material F (e.g., cereal; FIG. 4) before, during, or after sealing the respective bag at the top and/or the bottom. The bag 13 could be otherwise formed and/or any of the features of the bag 13 could be otherwise shaped, arranged, positioned, and/or configured, without departing from the disclosure. For example, the bag used in the package 15 could be any suitable bag. In one embodiment, the bag used in the package 15 could be any suitable bag or liner wherein at least a portion of a seal is oblique with respect to a top of the bag to at least partially form a dispenser feature 17.
In an alternative embodiment, shown schematically in FIG. 6, the alternative bags 13′ each have an alternative top seal 83′, which is oblique along its entire length. Accordingly, each of the bags 13′ has a longer dispenser feature 17′ that tapers from one top corner of the bag to the other.
According to one exemplary method of construction, the carton 5 may be erected by folding the blank 3 about the lateral fold lines 25, 29, 33, 37 so that the attachment flap 35 is adhesively secured to or otherwise attached to the back panel 21 (e.g., by a glue strip G; FIG. 1), and the blank 3 is formed into a generally open-ended sleeve (not shown) with an interior 89 (FIGS. 8 and 9). In one embodiment the bottom of the partially erected carton 5 can be closed by folding the bottom flaps 41, 45, 49, 53 inwardly, to at least partially overlap the bottom end flaps and close the bottom end 9 of the carton 5. In one embodiment, the first side bottom flap 45 can overlap the back and front bottom flaps 41, 49 and can be glued to the same (e.g., by glue strips G; FIG. 1), and the second side bottom flap 53 can overlap the first bottom closure flap 45 and can be glued to the same (e.g., by glue strips G; FIG. 1).
Similarly, the top 9 of the carton 5 can be closed by folding and at least partially overlapping the top flaps 39, 43, 47, 51, 55, 57. As shown in FIG. 7, the flaps 51, 57, which are connected at the tear line 61, are folded over the top of the carton 5 to overlap the respective back and front top flaps 39, 47, and the back top flap 39 can be glued to the second side top flap 51 (e.g., at a glue strip G; FIG. 1). In one embodiment, the front top flap 47 is not glued to the second dispenser flap 57. The flaps 43, 55 can be folded over to overlap the respective flaps 51, 57. In the illustrated embodiment, the first side top flap 43 can be glued to the second side top flap 51 (e.g., by glue strips G; FIG. 1), and the glue portion 67 of the first dispenser flap 55 can be glued to the second dispenser flap 57 (e.g., by glue strips G; FIG. 1). In one embodiment, the tear strip 63 and the reclosable flap 69 of the first dispenser flap 55 are not glued to the second dispenser flap 57. The erected carton 5 is shown in FIG. 7. The carton 5 could be otherwise formed without departing from the disclosure.
In one embodiment, the bag 13 with a product such as the flowable material F (FIG. 4) may be placed in the interior space of the partially formed carton 5 (e.g., before either or both of the ends 7, 9 is closed). The bag 13 can be loaded and/or sealed prior to, during, or after the bag is loaded into the carton 5. The bag 13 and/or the product can be otherwise loaded and/or inserted into the carton 5 without departing from the disclosure. For example, in one embodiment, the carton 5 could be formed around a formed or partially formed bag 13. The assembled package 15 is shown in FIGS. 7-9.
In the illustrated embodiment, the dispenser 11 is positionable between an initially closed position (FIG. 7) and an open or dispensing position (FIGS. 8 and 9) that provides access to the products held in the carton 5. Additionally, the dispenser 11 includes features that allow the dispenser to be closed (e.g., reclosed) after access to the products is no longer needed. To activate the dispenser 11, the tear strip 63 is first torn and removed so that the reclosable lid flap 69 is free from attachment to the distal or glue portion 67 of the first dispenser flap 55, wherein the distal portion 67 is adhesively attached to the second dispenser flap 57. After removing the tear strip 63, the reclosable lid flap 69 can be pivoted upwardly about the longitudinal fold line 62, separating the first dispenser flap from the first side top flap 43 along the cut or tear line 59. The second dispenser flap 57 also can be separated from the second side top flap 51 along the tear line 61 and pivoted upwardly about the longitudinal fold line 62. As shown in FIGS. 8 and 9, the front top flap 47 can be pivoted upwardly along the longitudinal fold line 62 so that the dispenser 11 is in the open position providing access to the interior 89 of the carton 5. The dispenser 11 could be otherwise opened without departing from the disclosure.
As shown in FIGS. 8 and 9, the dispenser feature 17 of the bag 13 in the interior 89 of the carton 5 can be accessed via the open dispenser 11. A user can grasp the sidewalls of the bag 13 in the dispenser feature 17, and pull the sidewalls apart to separate the sidewalls along at least a portion of the top seal 83 to open the bag 13 at the dispenser feature 17. The flowable material F in the bag 13 can be poured and/or otherwise removed from the package 15 through the opened dispenser feature 17 in the bag and the open dispenser 11 in the carton 5 such as by tipping the package 15 (FIG. 9). The spout 75 can be shaped to help direct the pouring of the flowable material F. For example, in one embodiment, the side panels 23, 31 of the carton 5 can be squeezed together slightly, which can cause the front top flap 47 and/or the front panel 27 to fold along the fold lines 77a, 77b, 77c, 77d as shown in FIG. 9. As shown in FIGS. 8 and 9, the top end 7 of the carton 5 remains closed where the back top flap 39, the first side top flap 43, and the second side top flap 51 overlap even when the dispenser 11 is open. Accordingly, the overlapped flaps 39, 43, 51 can help retain the bag 13 in the interior 89 of the carton 5 while the package 15 is tipped to dispenser the flowable material F. The flowable material F could be otherwise removed from the package 15 without departing from the disclosure.
In the illustrated embodiment, the dispenser 11 can be moved to a closed position after the initial opening. For example, the front top flap 47, the second dispenser flap 57 and the reclosable flap 69 can be folded along the longitudinal fold line 62 so that the reclosable flap 69 partially overlaps the second dispenser flap 57. The closing tab 71 can be inserted into the notch 73 and tucked under the edge of the second dispenser flap 57 to help retain the dispenser 11 in the closed position. Subsequently, the dispenser 11 could be opened by pivoting the flaps 69, 57, 47 upwardly. The dispenser 11 could be otherwise repositioned between the open and closed positions without departing from the disclosure.
FIG. 10 is a plan view of a blank 103 for forming a carton 105 and a package 115 (FIGS. 11 and 12) 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. 10, a liner patch 191 (e.g., comprising paper, foil, polymer film, and/or laminates and/or other combinations thereof) can be attached to the blank 103. For example, the liner patch 191 can overlap portions of the side panels 23, 31, the front panel 27, the first and second dispenser flaps 55, 57, and the front top flap 47. In one embodiment, the liner patch 191 is glued to these panels and flaps or to a portion thereof. In the second embodiment, the liner patch 191 is glued and/or otherwise secured to an interior surface of the blank 103. While FIG. 10 shows an exterior view of the blank 103, the liner patch 191 is visible through the blank 103 for the purpose of illustration. The liner patch 191 could be otherwise shaped, arranged, positioned, and/or configured, without departing from the disclosure.
As shown in FIGS. 11 and 12, the liner patch 191 can form a barrier in the open dispenser 11 that can help protect the flowable material F while it is poured through the dispenser and/or can provide a smooth continuous surface around the interior of the flaps 47, 57, 69 at the open dispenser 11. Accordingly, the liner patch 191 extends from the interior 89 of the carton 5 through the dispenser 11. The liner patch 191 can help guide the flowable material F through the dispenser 11 as it is poured from the package 115, and it can help to improve sift resistance and reduce clumping and bridging of the flowable material in the dispenser 11. In one embodiment, the closing the dispenser 11 can form a gusset in the liner patch 11. For example, as the flaps 47, 57, 69 are folded downwardly portions of the liner patch 191 are overlapped (e.g., in a triangle shape). Accordingly, the liner patch 191 can help to reduce leaking of the product through the reclosed dispenser 11.
FIG. 13 is a plan view of a blank 203 for forming a carton 205 and a package 215 (FIGS. 14-16) of a third embodiment of the disclosure. The third 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. 13, the blank 203 includes features for forming a dispenser 211 that extends in an oblique direction between the top 207 and the front panel 27 (FIGS. 14-16). In the illustrated embodiment, the portions 262a, 262b of the fold line 262 that connect the respective dispenser flaps 255, 257 to the respective side panels 23, 31 are oblique so that the front top flap 47 is recessed with respect to the side top flaps 243, 251. The dispenser flaps 255, 257 can be separated from the respective side top flaps 243, 251, and a tab 293 can be foldably connected to the second side top flap 251 along a fold line 261. The blank 203 could be otherwise shaped, arranged, positioned, and/or configured, without departing from the disclosure.
When the carton 205 is formed (e.g., in the same or a similar manner as in the first embodiment), the dispenser 211 extends obliquely in the front, top corner of the carton. The second dispenser flap 257 generally overlaps the front top flap 47 and the tab 293, and the first dispenser flap 255 generally overlaps the second dispenser flap 257. The glue portion 267 of the first dispenser flap 255 can be glued to the second dispenser flap 257. In the illustrated embodiment, the dispenser 211 can be opened (FIG. 15) and closed (FIG. 16) in a similar or the same manner as the dispenser 11 of the first embodiment. In one embodiment, the oblique configuration of the dispenser 211 can help provide differentiation of the package 215 on a store shelf. The carton 205 and/or the dispenser 211 could be otherwise formed without departing from the disclosure.
FIG. 17 is a plan view of a blank 303 for forming a carton 305 and a package 315 (FIGS. 18-21) of a fourth embodiment of the disclosure. The fourth 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. 17, the back panel 321 is foldably connected to the second side panel 31 along lateral fold line 325, and the attachment flap 335 is foldably connected to the back panel 321 along lateral fold line 337. In the illustrated embodiment, the blank 303 has dispenser features 311 that extend along the top portion of the blank, including a first dispenser flap 355, a second dispenser flap 369, a front top flap 347, and a back top flap 339. The front top flap 347 can be foldably connected to the first dispenser flap 355 and the second dispenser flap 357 along respective gusset panels 390a, 390b, and the back top flap 339 can be foldably connected to an attachment tab 388 and the second dispenser flap 357 along respective gussets panels 392a, 392b. In one embodiment, the gusset panels 390a, 390b are foldably connected to the front top flap 347 along respective oblique fold lines 394 and to the respective dispenser flaps 355, 357 along the respective lateral fold lines 29, 33. Similarly, the gusset panels 392a, 392b can be foldably connected to the back top flap 339 along respective oblique fold lines 395 and to the respective attachment tab 388 and second dispenser flap 357 along the respective lateral fold lines 337, 325.
As shown in FIG. 17, the second dispenser flap 357 can include a distal glue portion 367 separable from a reclosable flap 369 along a tear line 363. An access aperture 365 can be formed in the reclosable flap 369 for grasping the reclosable flap 369 and pulling upwardly to tear the reclosable flap 369 from the glue portion 367 along the tear line 363 to open the dispenser 311 (FIG. 19). As shown in FIG. 17, a longitudinal fold line can extend across the distal glue portion 367. The blank 303 could be otherwise shaped, arranged, positioned, and/or configured, without departing from the disclosure.
In the fourth embodiment, when the carton 305 is formed, the attachment flap 335 is attached (e.g., glued) to the interior surface of the first side panel 23 and the attachment tab 388 is attached (e.g., glued) to the interior surface of the first dispenser flap 355. Accordingly, the gusset panel 392b connects the back top flap 339 to the first dispenser flap 355 via the attachment tab 388. In the illustrated embodiment, the top 307 of the carton 305 can be closed by folding the top flaps 339, 347 inwardly over the open top. In one embodiment, this can cause the gusset panels 390a, 390b, 392a, 392b to fold inwardly and overlap the respective top flaps 347, 339 and the dispenser panels 355, 357 to fold downwardly and overlap the respective gusset panels 390a, 392a and 390b, 392b. The second dispenser flap 357 can partially overlap the first dispenser flap 355, and the glue portion 367 of the second dispenser flap 357 can be glued to the first dispenser flap 355 (e.g., by a glue strip G; FIG. 17). The carton 305 could be otherwise formed and/or the top 307 could be otherwise closed without departing from the disclosure.
As shown in FIG. 19, the dispenser 311 can be opened by grasping the reclosable flap 369 at the access feature 365, pulling upwardly to tear the reclosable flap 369 away from the glue portion 367 along the tear line 363, and pivoting the reclosable flap 369 upwardly top open the top 307 of the carton 305. Since the first dispenser flap 355, the reclosable flap 369, and the top flaps 347, 339 are interconnected by the gusset panels 390a, 390b, 392a, 392b, the pivoting of the reclosable flap 369 can cause the first dispenser flap 355 and the top flaps 347, 339 to pivot upwardly as well. As shown in FIGS. 20A and 20B, the top 307 can be closed by folding the first dispenser flap 355, the reclosable flap 369, and the top flaps 339, 347 downwardly over the top and tucking the first dispenser flap 355 partially under the reclosable flap 369. In one embodiment, the top of the bag 13 can be at least partially trapped between the reclosable flap 369 and the first dispenser flap 355 to help close (e.g., at least partially seal) the top of the bag 13, which can help keep the contents of the bag fresh. The reclosed carton 305 is shown in FIG. 21 in one example. In one exemplary embodiment, a top portion of the bag 13 can be glued to the reclosable flap 369 so that the top of the bag is folded and sandwiched between the reclosable flap 369 and the first dispenser flap 355 when the dispenser 311 is closed. The dispenser 311 could be otherwise opened and/or closed without departing from the disclosure.
FIG. 22 is a perspective view of a package 415 including a carton 405 formed from at least one blank (not shown) in a fifth embodiment of the disclosure. The fifth 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. 22, the dispenser 411 includes a flip top 496 that is separable from the side panels 423, 431 and the front panel 427 by a tear strip 463. The flip top 496 is foldably connected to a top wall 497 of the carton 405 formed by the first side top flap 443, the second side top flap 451 (FIGS. 24A and 24B), and/or other top flaps (not shown) along a fold line 459. As shown in FIGS. 23-24A, the dispenser 411 can be opened by tearing the tear strip 463 away from the carton and pivoting the flip top 496 upwardly along the fold line 459.
As shown in FIGS. 24A and 24B, the dispenser 411 can include features for helping the flip top 496 to stay open during dispensing of the flowable material F and/or to stay closed for storage. For example, a front wall insert 498 can be glued to the interior surface of the front panel 427 and the side panels 423, 431. The front wall insert 498 can include a foldably-connected front locking tab 471, and a locking insert 499 can be glued or otherwise secured to an interior of the flip top 496. The locking insert 499 can have an aperture 473 for receiving the front locking tab 471 so that the interaction between the front locking tab 473 and the locking insert 499 can help retain the flip top 496 in the closed position. In the illustrated embodiment, a first interference tab 472 can extend from the second side top flap 451 and a second interference tab 474 can extend from a rear portion of the flip top 496. As shown in FIGS. 24A and 24B, the interference tabs 472, 474 can interfere with the movement of one another so that the interference tab 474 forces the interference tab 472 and the second side top flap 451 to flex and/or pivot downwardly as the flip top 496 pivots open or closed. Accordingly, the interference tabs 472, 474 can help retain the flip top 496 in the open or closed position. In one embodiment, the interaction of the locking features can cause an audible noise (e.g., a “click,” “snap,” or other sound) to indicate to the user that the dispenser 411 is closed. The package 415 could be otherwise shaped, arranged, positioned, 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. Further, the panels, flaps, dispensers, bags, and/or other features shown and described in conjunction with the blanks 3, 103, 203, 303, the cartons 5, 105, 205, 305, 405, and/or the packages 15, 115, 215, 315, 415 of the above embodiments are included by way of example. The dispensers, bags, and/or other features of the disclosure can alternatively be associated with any suitable carton having any panel and flap configuration.
The cartons according to the present disclosure can be, for example, formed from blanks of coated paperboard and similar materials. For example, the interior and/or exterior sides of the blanks 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 blanks may then be coated with a varnish to protect any information printed on the blank. The blanks 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 blanks may be constructed of paperboard of a caliper such that it is heavier and more rigid than ordinary paper. The blanks 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 blanks 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 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.
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, flaps, or features, 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 that are within the scope of the claims. Additionally, the disclosure shows and describes only selected embodiments of the disclosure, but the disclosure is capable of use in various other combinations, modifications, and environments and is capable of changes or modifications within the scope of the inventive concept 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.
