DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS
The present disclosure generally relates to cartons (e.g., carriers) with features for containing and facilitating dispensing articles such as food products, cooked food products, fried food products, hot and/or moist articles, etc. The articles can include, but are not limited to, fast food products, take-out products, meal leftovers, and the like, or any combination thereof. Examples of such products include, but are not limited to, fish, chicken, French fries, French toast sticks, sandwich, pizza, calzone, turnover, burrito, or any other food product that may be packaged for consumption by a consumer. In this specification, the terms “inner,” “interior,” “outer,” “exterior,” “lower,” “bottom,” “upper,” and “top” indicate orientations determined in relation to fully erected and upright cartons.
FIG. 1 is a plan view of a blank, generally indicated at 1, used to form a carton 3 (FIGS. 2-7) of a first embodiment of the disclosure. The carton 3 can be used to hold a food product (not shown) such as a fast food product (e.g., French fries) in an interior 5 of the carton (FIGS. 2, 3, and 7). In one embodiment, the carton 3 can be sized to fit in a hand and/or can be generally tapered (FIGS. 2-4). In one embodiment, the carton 3 can be used for holding, packaging, and/or serving cooked/fried food products from a fast food or quick service restaurant, but the carton could hold other types of food products or other non-food products without departing from the disclosure. In the illustrated embodiment, the carton 3 includes an integrated lid or cover, generally indicated at 7, and a dispenser, generally indicated at 9 (FIGS. 3-6).
In the illustrated embodiment, the blank 1 has a longitudinal axis L1 and a lateral axis L2. The blank 1 includes a bottom panel 10 foldably connected to a first side panel 12 at a first fold line 14, a second side panel 16 foldably connected to the bottom panel 10 at a second fold line 18, and a top panel 20 foldably connected to the second side panel 16 at a tear line 22. Alternatively, the top panel 20 could be foldably connected to the second side panel 16 or the first side panel 12 along a fold line or other line of weakening. A first end panel 24 and a second end panel 26 are respectively foldably connected to the first side panel 12 along respective fold lines 28, 30. Attachment flaps 32, 34 are foldably connected to the respective first end panel 24 and second end panel 26 along respective fold lines 36, 38. As shown in FIG. 1, the fold lines 14, 18 connecting the bottom panel 10 to the respective side panels 12, 16 are generally arcuate or crescent-shaped so that the bottom panel 10 is curved toward the interior 5 of the carton 3 (e.g., concave) when the carton 3 is formed (FIGS. 3, 4, and 6).
In the illustrated embodiment, the first and second end panels 24, 26 have respective fold lines 40, 42 that divide each of the end panels into respective end portions 44a, 44b, and 46a, 46b. Similarly, the bottom panel 10 includes a fold line 48 that divides the bottom panel into portions 50a, 50b. In the first embodiment, the end portions 44a, 44b of the end panel 24 are angled with respect to each other when the carton 3 is formed from the blank 1 such that the side panel 24 is generally non-planar (FIGS. 2-6). Similarly, the end portions 46a, 46b of the end panel 26 are angled with respect to each other in the assembled carton 3 such that the end panel 26 is generally non-planar. Additionally, the fold lines 40, 42, 48 can help the carton 3 to collapse to be generally flat for shipping when the end panels 24, 26 and the bottom panel 10 are folded along the respective fold lines 40, 42, 48 so that the end portions 44a, 46a, 50a are brought into face-to-face contact with the respective end portions 44b, 46b, 50b, and the first side panel 12 is brought into face-to-face contact with the second side panel 16. The blank 1 could have other end panel arrangements without departing from the disclosure. Additionally, the bottom panel 10, the side panels 12, 16, the top panel 20, the end panels 24, 26, and/or the attachment flaps 32, 34 could be otherwise shaped, arranged, positioned, and/or configured without departing from the disclosure.
In the illustrated embodiment, the lid 7 can include the top panel 20 and closure features (FIGS. 1 and 2) for helping to close the lid 7. The closure features can include a closure tab 52 (e.g., a first closure feature) extending from an edge of the top panel 20. The closure tab 52 can be configured to engage a closure slot 54 (e.g., a second closure feature comprising an arcuate cut line or another opening or receiving feature) in the first side panel 12. In the illustrated embodiment, the closure slit 54 is spaced apart from an upper edge of the first side panel 12. The lid 7 including the closure features, the top panel 20, and/or the first side panel 12 could be omitted or could be otherwise shaped, arranged, and/or configured without departing from the disclosure. For example, alternative closure features are shown in FIGS. 3, 4, and 7, wherein the closure tab 52′ has a different shape than the closure tab 52, and the closure slot 54′ includes a slit and an opening in communication with the slit.
Additionally, in the illustrated embodiment, the blank 1 can include dispensing features for forming the dispenser 9 (FIGS. 4-6) so that the carton 3 can be opened to form a serving vessel 56 (FIG. 7) for the food product in the carton 3. As shown in FIG. 1, the dispensing features include a dispenser panel 57, which comprises the top panel 20 in the first embodiment, and the tear line 22, which foldably connects the top panel 20 to the second side panel 16 in the first embodiment. In an alternative embodiment, the dispenser panel 57 could include at least a portion of any of the side and/or end panels of the blank 1 and/or could include less than the entire top panel 20. An access flap 58 can be included in the top panel 20 and/or the side panel 16 to help initiate tearing along the tear line 22 when removing the top panel 20 to access the food product in the interior 5 of the carton 3. The dispensing features could be otherwise shaped, arranged, and/or configured without departing from the disclosure. For example, the access flap 58 could be an access opening or other feature. In one embodiment, the access flap 58 can serve as a vent flap in the carton 3. Further, the dispensing features could include additional or alternative tear lines and/or tear strips for removing at least portions of the top panel 20, the side panels 12, 16, the end panels 24, 26, the attachment flaps 32, 34, and/or the bottom panel 10.
As shown in FIG. 2, the carton 3 can be at least partially formed from the blank 1 by folding along fold lines 14, 18 so that the side panels 12, 16 are generally opposed, and folding along fold lines 28, 30, 40, 42, 36, 38 so that the end flaps 24, 26 at least partially close the ends of the carton 3 and the attachment flaps 32, 34 are at least partially in face-to-face contact with the second side panel 16. In the illustrated embodiment, the attachment flaps 32, 34 can be glued to an exterior surface of the second side panel 16 (e.g., at glue areas 60). Alternatively, the attachment flaps could be glued or otherwise secured to the interior surface of the second side panel 16. In one embodiment, the carton 3 can be shipped to a restaurant or other food service location in a partially assembled and laid-flat condition, wherein the end panels 24, 26 are folded along the respective fold lines 40, 42 and the bottom panel 10 is folded along the fold line 48 so that the portions 44a, 46a, 50a are at least partially in face-to-face contact with the respective portions 44b, 46b, 50b and the side panels 12, 16 are at least partially in face-to-face contact with one another. Prior to placement of food product within the carton 3, the blank 1 can be formed into the carton 3 having an open top (FIGS. 2 and 3) by folding the end panels 24, 26 and the bottom panel 10 along the respective fold lines 40, 42, 48. The interior 5 of the carton 3 is at least partially enclosed by the side panels 12, 16, the end panels 24, 26, and the bottom panel 10. As shown in FIGS. 2-6, the bottom edges 25, 27 of the respective end panels 24, 26 are generally straight and horizontal so that the carton 3 can be generally free standing on a flat surface (e.g., the carton 3 can rest on the bottom edges 25, 27 of the end panels 24, 26). The carton 3 could be otherwise shaped, arranged, and/or configured without departing from the disclosure.
The carton 3 can be filled with a food product, such as by using a scoop (e.g., fry scoop, not shown) or other tools, or by using the open carton 3 as a scooper. The lid 7 can be closed by folding the top panel 20 along the tear line 22 and bending the top panel so that the top panel is curved and the closure tab 52 or 52′ extends generally downwardly. The closure tab 52 or 52′ can be inserted into the closure slot 54 or 54′ from the interior side or the exterior side of the first side panel 12. The closed carton 3 with the closed integrated lid 7 is shown in FIGS. 4-6. Accordingly, the food product (e.g., cooked and/or fried potatoes or other products) can be protected and experience reduced product degradation relative to an open carton when transporting the carton 3 and the food product from a store or restaurant (e.g., a quick service restaurant or other stores or restaurants). For example, the closed carton 3 can help maintain product attributes (e.g., heat retention, crispness/crunch, texture—bite, break, just-cooked taste, and/or other features), product protection (e.g., product uniformity, reduced product breaking, reduced crushing, reduced loss of product by spilling, etc., and/or other attributes), and/or minimum product degradation (e.g., heat/moisture balance maintained so that the product is not soggy or limp and/or other features). Alternative loading and closing steps could be used without departing from the disclosure.
As shown in FIG. 7, the dispenser 9 can be actuated to open the closed carton 3 by tearing the dispenser panel 57 (including the top panel 20) away from the second side panel 16 along the tear line 22 and removing the closure tab 52 or 52′ from the closure slot 54 or 54′ to form a dispenser opening 59. Alternatively, the carton could be opened by removing the closure tab 52 from the closure slot 54 and folding the lid 7 upwardly along the tear line 22. The top panel 20 could then remain attached to the side panel 16 (e.g., FIGS. 2 and 3) or be torn away from the side panel 16. Accordingly, the carton 3 forms the serving vessel 56 where the food product in the interior 5 of the carton can be accessed through the open top of the carton 3. Accordingly, the dispenser 9 provides easy access to the food product at the dispenser opening 59. Other opening and serving steps could be used without departing from the disclosure.
FIG. 8 is a plan view of a blank 101 for forming a carrier 103 (FIGS. 9-15) according to 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. 8, the blank 101 includes vent features 170 in integrated lid 107 (including the top panel 120) and in the portions 144b, 146b of the respective end panels 124, 126. Additional or alternative vent features could be included in the panels and flaps of the blank 101 without departing from the disclosure. Each of the vent features 170 can include a vent flap 172 foldably connected to the top panel 120, the first end panel 124, or the second end panel 126 along a respective fold line 174. Each of the vent features 170 can be at least partially defined by a cut or tear line 176. In one embodiment, the tear lines 176 can include one or more nicks to help hold the vent flap 172 in place until the vent features 170 are actuated.
As shown in FIGS. 13-15, the vent features 170 can be actuated to form vent openings 178 by folding the vent flaps 172 inwardly along the fold lines 174. Alternatively, one or more of the vent flaps 172 could be folded outwardly. Accordingly, the vent flaps 172 can be folded inwardly or outwardly along the respective fold lines 174 to move the vent features 170 from a closed position (FIGS. 9-11) to an open or actuated position (FIGS. 13-15). When the vent flaps 172 are actuated, the vent features 170 can at least partially vent the carton 103 so that gases (e.g., steam and/or other forms of moisture and/or other gases or liquids) can enter and/or escape the interior 5 of the carton 103. Accordingly, the vent features 170 can help the carton 103 maintain the product quality as described above. For example, the enclosed interior 5 of the carton with the closed integrated lid 7 can help maintain the heat of fried potatoes, for example, while moisture (e.g., from steam from the fried potatoes) in the interior 5 can escape the carton 3 via one or more of the vent openings 178. Accordingly, the build-up of moisture in the interior 5 of the carton 3 is reduced or eliminated, and the fried potatoes can maintain their product attributes (e.g., can remain hot and crisp) longer than if they were contained in an open container (e.g., no lid) or an enclosed container with no vent features. The vent features 170 could be otherwise shaped, arranged, positioned, and/or configured without departing from the disclosure.
As shown in FIG. 8, the bottom panel 110 can include oblique edges so that the fold line 148 connecting the portions 150a, 150b of the bottom panel is longer relative to the fold line 48 of the first embodiment. The blank 101 and the carton 103 could be otherwise shaped, arranged, and/or configured without departing from the disclosure.
FIG. 16A is a plan view of a blank 201 for forming a carrier 203 (FIGS. 16B-16D) according to a third embodiment of the disclosure. The third embodiment is generally similar to the second 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. 16A, the blank 201 includes a first top panel 220 foldably connected to the second side panel 16 along an arcuate fold line 222 and a second top panel 221 foldably connected to the first side panel 12 at an arcuate fold line 223. The top panels 220, 221 cooperate to form the integrated lid 207 (FIGS. 16B-16C) in the carton 203. In the illustrated embodiment, blank 201 includes closure features, including a closure tab 252 extending from the second top panel 221 and a closure slot or opening 254 disposed in the first top panel 220. In one embodiment, the closure slot 254 is spaced apart from the edge of the first top panel 220. The closure features can help retain the lid 207 in a closed position (FIGS. 16C and 16D) when the top panels 220, 221 are downwardly folded along the respective fold lines 222, 223 from the open position (FIG. 16B) to the closed position (FIGS. 16C and 16D), the closure tab 252 can be at least partially inserted into the closure slot 254. As shown in FIGS. 16C and 16D, the second top panel 221 partially overlaps the first top panel 220 so that the closure tab 252 is received in the closure slot 254 from above. Alternatively, the first top panel 220 can partially overlap the second top panel 221 so that the closure tab 252 extends upwardly into the closure slot 254. The lid 207 could be otherwise shaped, arranged, positioned, and/or configured without departing from the disclosure.
In the illustrated embodiment, the blank 201 includes vent features 270. The vent features 270 can include two spaced apart vent openings 278 in each of the end portions 244b, 246b of the respective end panels 224, 226. The vent openings 278 can perform similarly to the vent openings 178 formed by the vent flaps 172 in the second embodiment (FIGS. 13-15). As shown in FIGS. 16C and 16D, the vent features further can include upper vent openings 280 defined between the integrated lid 207 and the respective end panels 224, 226. In one embodiment, the end portions 244a, 244b of the end panel 224 extend in an oblique direction from the side panels 12, 16 to the fold line 40 so that the end panel 224 has a generally V-shaped cross-section. Similarly, the end portions 246a, 246b of the end panel 226 extend in an oblique direction from the side panels 12, 16 to the fold line 42 so that the end panel 226 has a generally V-shaped cross-section. Accordingly, at the top of the carton 203, the fold lines 40, 42 of the respective end panels 224, 226 are spaced apart from the lid 207, and at least a portion of each of the end portions 244a, 244b, 246a, 246b proximate the respective fold lines 40, 42 are spaced apart from the lateral edges 282 of the top panels 220, 221 to form the upper vent openings 280. The vent openings 278, the vent openings 280, and/or other vent features could be omitted or could be otherwise shaped, arranged, positioned, and/or configured without departing from the disclosure.
As shown in FIG. 16A, the end panels 224, 226 of the third embodiment can have a generally different shape than the side panels of the first and second embodiments. The blank 201 and the carton 203 could be otherwise shaped, arranged, and/or configured without departing from the disclosure.
FIG. 17A is a plan view of a blank 301 for forming a carrier 303 (FIGS. 17B-17D) according to a fourth embodiment of the disclosure. The fourth embodiment is generally similar to the third 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. 17A, the blank 301 includes a first top panel 320 foldably connected to the second side panel 16 along an arcuate tear line 322, and the first top panel 320 forms a first portion 357a of the dispenser panel 357 (FIGS. 17B-17D). Alternatively, the first top panel 320 could be connected to the second side panel 16 along a fold line or other line of weakening. The second top panel 321 is foldably connected to the first side panel 312 along an arcuate fold line 323, and the second top panel 321 can include several vent features 170. The vent features 170 could be omitted, or any suitable number of vent features could be included in the blank 301.
As shown in FIGS. 17B and 17C, the top panels 320, 321 cooperate to form the integrated lid 307 of the carton 303. In the illustrated embodiment, the lid 307 includes closure features, including a closure tab 352 in the first top panel 320. The closure tab 352 can be defined by a cut line or closure slit 354, which is spaced apart from the edges of the first top panel 320 and the fold line 322. The closure features can also include an edge 353 of the second top panel 321 that is at least partially received in the closure slit 354 when the lid 307 is closed (FIGS. 17B and 17C). The closure edge 353 can include a notch (FIG. 17A) in the second top panel 321. Alternatively, the edge 353 could be continuous with the outer edge of the second top panel. As shown in FIGS. 17B and 17C, when the lid 307 is closed, the closure edge 353 of the second top panel 321 can be at least partially received in the closure slot 354 in the first top panel 320 so that the closure tab 352 at least partially overlaps the second top panel 321 adjacent the closure edge 353. Alternatively, the first top panel 320 can at least partially overlap the second top panel 321 and the edge 353 can be at least partially received in the closure slit 354 from below the first top panel 320 so that the second top panel 321 adjacent the edge 353 at least partially overlaps the closure tab 352. The integrated lid 307, including the top panels 320, 321 and/or the closure features, could be omitted or could be otherwise shaped, arranged, positioned, and/or configured without departing from the disclosure.
As shown in FIG. 17A, the blank 301 includes a vent feature 370 in each of the end panels 324, 326. Alternatively, the blank 301 could include any suitable number of vent features 370, or the vent features 370 could be omitted. The vent features 370 can include a vent flap 372 foldably connected to the respective end panel 324, 326 along a respective fold line 374 and can be separable from the respective end panel 324, 326 along a respective cut or tear line 376. In the illustrated embodiment, the vent feature 370 in the first end panel 324 extends in both of the end portions 344a, 344b so that the fold line 40 extends across the vent flap 372. Similarly, the vent feature 370 in the second end panel 326 extends in both of the end portions 346a, 346b so that the fold line 42 extends across the vent flap 372. The vent features 370 and/or the end panels 324, 326 could be omitted or could be otherwise shaped, arranged, positioned, and/or configured without departing from the disclosure.
As shown in FIGS. 17B and 17C, the carton includes a dispenser 309 including a dispenser panel 357 at least partially defined by tear lines 322, 384a, 384b. As shown in FIG. 17A, the blank 301 includes dispenser features for forming the dispenser 309 in the carton 303. The dispenser features can include a first dispenser panel portion 357a, comprising the first top panel 320 and at least partially defined by the tear line 322. The dispenser features can also include a second dispenser panel portion 357b, comprising the second top panel 321, a portion of the first side panel 312 defined between the arcuate fold line 323 and the tear lines 384a, 384b, and portions of the end panels 324, 326 respectively defined between a respective edge of the end panel 324, 326 and the respective tear line 384a, 384b.

The blanks 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 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 blanks. 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 blanks can also be constructed of other materials, such as cardboard, hard paper, or any other material having properties suitable for enabling the cartons, to function at least generally as described above. The blanks 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.
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 spaced apart slits to be replaced with a continuous slit, a continuous score, 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. Also, a tear line can be a series of cut scores passing completely, or partially, through the material, that are separated by nicks.
