DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS
The present disclosure generally relates to cartons that contain a single article or a plurality of articles such as containers, bottles, cans, etc., and protection features of such cartons that protect the article or articles or containers from breakage, damage, or deformation. The article(s) can be used for packaging food and beverage products, for example, or any other item. The article(s) can be made from materials suitable in composition for packaging the particular food or beverage item, or other item, and the materials can include, but are not limited to, glass or other breakable material; aluminum and/or other metals; plastics such as PET, LDPE, LLDPE, HDPE, PP, PS, PVC, EVOH, and Nylon; paperboard; and the like, or any combination thereof, or any other suitable material.
Cartons according to the present disclosure can accommodate articles of any shape. For the purpose of illustration and not for the purpose of limiting the scope of the disclosure, the following detailed description describes beverage containers (e.g., glass beverage bottles) as disposed within the carton embodiments. In this specification, the terms “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. 8) according to a first exemplary embodiment of the disclosure. The carton 5 can be used to house a plurality of articles such as containers C (FIG. 3). In the illustrated embodiment, the containers C are bottles having a wide bottom B and a narrow top T including a cap CP. In the illustrated embodiment, the carton 5 is sized to house eighteen containers C in a single layer in a 3×6 arrangement, but it is understood that the carton 5 may be sized and shaped to hold containers of a different or same quantity in more than one layer and/or in different row/column arrangements (e.g., 1×6, 2×6, 4×6, 3×8, 2×6×2, 3×4×2, 2×9, 3×4, etc.), or just a single article.
In one embodiment, the carton 5 has a first end 7 and a second end 9 each having article protection features 11, 11A, 11B (FIG. 8) for protecting at least one article C of the plurality of articles. Alternative, only a single article C could be provided in the carton 5. As will be further discussed below, the carton 5 of the first embodiment may have article protection flaps 13 for protecting the at least one article. The article protection features 11 cushion the ends 7, 9 of the carton and prevent or reduce the likelihood of breakage of the containers C. In one embodiment, the article protection flaps 13 are moveable between a first position (FIG. 10A) and a second position (FIGS. 8A and 10B) placed between adjacent containers C in the carton to reduce movement of the containers in the carton and prevent breakage of the containers. The carton 5 can have other features (e.g., handle, dispenser, etc.) without departing from the disclosure.
The blank 3 has a longitudinal axis L1 and a lateral axis L2. In the embodiment of FIG. 1, the blank includes a bottom panel 15 foldably connected to a first side panel 17 at a lateral fold line 19. A second side panel 21 is foldably connected to the bottom panel 15 at a lateral fold line 23. A top panel 25 is foldably connected to the first side panel 17 at a lateral fold line 27, and foldably connected to an adhesive panel 29 at a lateral fold line 31.
The bottom panel 15 is foldably connected to a first bottom end flap 33 and a second bottom end flap 35. The first side panel 17 is foldably connected to a first side end flap 37 and a second side end flap 39. The second side panel 21 is foldably connected to a first side end flap 43 and a second side end flap 45. The top panel 25 is foldably connected to a first top end flap 47 and a second top end flap 49. In one embodiment, when the carton 5 is erected, the end flaps 33, 37, 43, 47, close the first end 7 of the carton, and the end flaps 35, 39, 45, 49 close the second end 9 of the carton. In accordance with an alternative embodiment of the present disclosure, different flap arrangements can be used for closing the ends 7, 9 of the carton 5.
The end flaps 33, 37, 43, 47 extend along a first marginal area of the blank 3, and are foldably connected at a first longitudinal fold line 61 that extends along the length of the blank. The end flaps 35, 39, 45, 49 extend along a second marginal area of the blank 3, and are foldably connected at a second longitudinal fold line 63 that also extends along the length of the blank. The longitudinal fold lines 61, 63 may be, for example, substantially straight, or offset at one or more locations to account for blank thickness or for other factors. In one embodiment, the side panels 17, 21 have respective diamond panels 65 that are formed by a fold line 67 that is spaced inwardly from the respective longitudinal fold line 61, 63. Also, the side end flaps 37, 39, 43, 45 have a respective lateral fold line 69 extending from a diamond panel 65 to allow a respective end 7, 9 to angle inwardly so that the top of the carton 5 at each end (the portion of the fold line 61, 63 connecting the top end flap 47, 49) is closer to the center of the carton than the bottom of the carton at each end (the portion of the fold line 61, 63 connecting the bottom end flap 33, 35). In this way, the ends 7, 9 are tapered ends, but it is understood that the ends of the carton 5 could be otherwise shaped, arranged, and/or configured (e.g., straight or non-tapered) without departing from the disclosure.
In the embodiment of FIG. 1, the blank 3 has handle features for forming a handle 71. In the illustrated embodiment, the handle features comprise handle flaps 73 foldably connected to a respective top end flap 47, 49 at a longitudinal fold line 75, and notches or openings 77 in the side end flaps 37, 39, 43, and 45. The openings 77 cooperate to provide an opening at a respective closed end 7, 9 to allow a respective handle flap 73 to be inwardly folded so that the carton 5 can be grasped at a respective end. The blank 3 can have other features for forming the handle 71, or the blank and/or carton 5 can have a handle that is alternatively shaped, arranged, and/or configured without departing from the disclosure. Further, the handle 71 can be omitted without departing from the disclosure.
In one embodiment, the blank 3 has features for forming the article protection features 11 of the carton 5. As shown in FIG. 1, the side end flaps 37, 39, 43, 45 have deformations in the form of indentations 81 on the exterior surface of the blank 3 such that the indentations from a protrusion on the interior surface of the blank. The bottom end flap 33, 35 each have two rows of deformations in the form of indentations 83 on the interior surface of the blank 3 such that the indentations on the interior surface form a protrusion on the exterior surface 1 of the blank 3. As shown in FIG. 1, the top end flaps 47, 49 each have a respective distal edge 87, 89 having corner notches 91 and a center notch 93. The indentations 81, 83 can be any deformation on a surface of a respective side end flaps 37, 39, 43, 45 or bottom end flap 33, 35 such that the deformation can be any suitable shape (e.g., a concave depression or protrusion, convex depression or protrusion, flat depression or protrusion, embossed area, debossed area, etc., or any other suitable shape). Furthermore, the indentations 81, 83 could be formed on the interior or exterior surface of one or more of the first side panel 17, second side panel 21, top panel 25, bottom panel 15, or top end flaps 47, 49 without departing from the disclosure.
In the first embodiment, the blank 3 includes nine article protection flaps 13 arranged in a 3×3 arrangement, but the blank could have more or less than nine article protection flaps, and the flaps could be otherwise arranged in other suitable row/column arrangements or in a random configuration on the bottom panel 15, including a single row or single column configuration, or any other suitable configuration. The description herein will describe the detailed arrangement and configuration of a single article protection flap 13; however, the arrangement and configuration of the other article protection flaps will be similar or identical. In other embodiments, the blank 3 can include article protection flaps that are different, similar, or identical to other article protection flaps without departing from the disclosure. In the embodiment of FIG. 1, the middle row of article protection flaps 13 are oriented 180 degrees relative to a row of article protection flaps that are closer to a respective fold line 61, 63. In other embodiments, the article protection flaps 13 could be otherwise shaped, arranged, and/or configured without departing from the disclosure.
As shown in FIGS. 1 and 10A, the article protection flaps 13 are each foldably connected to the bottom panel 15 at a respective lateral fold line 101 and are each at least partially defined by a line of weakening 103 in the bottom panel. In one embodiment, the line of weakening 103 is a cut, but the line of weakening could comprises other forms of weakening (e.g., a tear line that comprises cut lines separated by breakable nicks, a tear line that is formed by a series of spaced apart cuts, etc.) that allows the article protection flap 13 to separate from the bottom panel 15 without departing from the disclosure. The cut 103 has a first portion 105 that is generally curved and extending from a first end 106 of the fold line 101 and a second portion 107 that is generally curved and extending from a second end 108 of the fold line 101. Both the first portion 105 and the second portion 107 of the cut 103 extend away from the fold line 101 and form a respective rounded corner 109, 111 of the cut that transitions to a third portion 113 of the cut. The third portion 113 is generally straight and extends in the lateral direction L2 between the two rounded corners 109, 111. In one embodiment, a slit or cut 112 is located adjacent the third portion 113 of the cut 103. As show in FIGS. 1 and 10A, the article protection flap 13 comprises a second fold line 117 extending from the first end 106 of the first fold line 101 and a third fold line 119 extending from the second end 108 of the first fold line. In the first embodiment, the second and third fold lines 117, 119 are longitudinal fold lines that are generally parallel and extend in the longitudinal direction L1 of the blank 3. The fold lines 101, 117, 119 and cuts 103, 105 could be otherwise shaped, arranged, configured, and/or omitted such that the article protection flap 13 has any other suitable shape or configuration without departing from the disclosure.
In one embodiment, the first portion 105 of the cut 103, the rounded corner 109 of the cut, a portion of the third portion 113 of the cut, and the second fold line 117 at least partially define a first portion 121 of the article protection flap 13. The second portion 107 of the cut 103, the rounded corner 111 of the cut, a portion of the third portion 113 of the cut, and the third fold line 119 at least partially define a second portion 123 of the article protection flap. A central portion 125 of the article protection flap is at least partially defined by the first fold line 101, second fold line 117, third fold line 119, and a portion of the third portion 113 of the cut 103. The first portion 121 of the article protection flap 13 is foldably connected to the central portion 125 at the second fold line 117. The second portion 123 of the article protection flap 13 is foldably connected to the central portion 125 at the third fold line 119. The first portion 121 and the second portion 123 are foldable relative to each other and the central portion 125 by way of the fold lines 117, 119. Alternatively, the first portion 121 and second portion 123 could be foldably connected at a single fold line without departing from the disclosure.
FIGS. 2-8 show one exemplary method of forming the carton 5 and the article protection features 11. As shown in FIG. 2, the blank 3 can be formed into a sleeve 131 having open ends 7, 9 by folding the bottom panel 15, side panels 17, 21, and top panel 25 along respective fold lines 19, 23, 27, 31. The adhesive panel 29 can be adhesively secured to the second side panel 21 by glue or other suitable adhesive. As shown in FIG. 3, containers C can be placed into an interior space 133 of the sleeve 131. One of the ends 7, 9 can be closed prior to loading the containers C or both of the ends 7, 9 can be closed after loading the containers into the interior space 133. The closing of the first end 7 is described below, but it is understood that the second end 9 can be closed in a similar manner, with the article protection features 11 in the second end being formed in a similar manner as the article protection features in the first end. Alternatively, the second end 9 could have different flap closing sequence or arrangement and the article protection features 11 could be otherwise shaped, arranged, configured, and/or omitted without departing from the disclosure.
As shown in FIGS. 3 and 4, the first end 7 is closed by first inwardly folding the side end flaps 37, 43. As shown in FIGS. 5-7, the bottom end flap 33 is upwardly folded and the top end flap 47 is downwardly folded to close the end 7 of the carton 5. The article protection features 11 in the first end of the carton 5 are formed during the closing of the end flaps 33, 37, 43, 47. As shown in FIG. 6, the indentations 81 on the exterior surface of the side end flaps 37, 43 are aligned with the indentations 83 on the interior surface of the bottom end flap 33 to form a respective article protection feature 11. As shown in FIGS. 8 and 9, the outermost article protection features (when viewing the end 7 as shown in FIG. 9) are identified by reference number 11A and are formed by the indentation 81 on the side end flap 43 and the indentation 83 on the bottom end flap 33 that cooperate to form a pocket 135 in the overlapped end flaps. In one embodiment, the width of the pocket 135 as viewed in FIG. 9 is approximately equal to the combined amount of depression of each of the indentations 81, 83. The indentations 81 are on the exterior surface of the side end flaps 37, 43 and the indentations 83 are on the interior surface of the bottom end flap 33 so that the indentations 81, 83 cooperate to form the pocket 135. Alternatively, the article protection features 11 could comprise only a single indentation 81, 83, or one of the indentations 81, 83 could be larger or smaller than the other, or the indentations 81, 83 could be offset from one another, without departing from the disclosure. Moreover, the indentations 81, 83 could be arranged such that the protrusions are in direct contact with each other.
In one embodiment, the middle article protection features 11B (FIGS. 8 and 9A) are formed by an indentation 81 on each of the side end flaps 37, 43 and an indentation on the bottom end flap 33. As shown in FIG. 9A, the indentation 81 near the edge of the inner side end flap 43 receives the indentation 81 near the edge of the outer side end flap 37, and the indentation 83 on the bottom end flap 33 cooperates with the indentation on the outer side end flap 37 to form the pocket 137. The article protection features 11A, 11B, and pockets 135, 137 could be otherwise shaped, arranged, positioned, and/or configured without departing from the disclosure.
FIGS. 9B and 9C show alternative configurations of the article protection features 11A, 11B having pockets 135, 137 similar to the embodiments of FIGS. 9 and 9A but filled with shock absorbing material 139. In one embodiment, the shock absorbing material 139 is a thermoplastic adhesive. The shock absorbing material 139 can comprise thermoplastic adhesive that can be hot-melt adhesive including a low temperature hot melt thermoplastic adhesive or a high temperature hot melt thermoplastic adhesive such as are commercially available. Such hot melt adhesive can include ethylene vinyl acetate (EVA) or any other suitable material. For example, the shock absorbing material 139 can comprise any suitable foam, gel, liquid, or solid, that can be located in the pocket 135, 137 and provide cushioning of the impact forces exerted on the carton 5. For example, the shock absorbing material could comprise any suitable heat activation material, UV activation material, laser activation material, Styrofoam, thermoplastic, hot melt adhesive, or any material that takes up space in the pocket 135, 137 to provide cushioning to the containers C. The article protection features 11 can comprise the same or different thermoplastic adhesive that is used to form and close the carton 5 without departing from the disclosure. In one embodiment, the adhesive used to form the shock absorbing material 139 can be further applied to one or more of the end flaps 33, 37, 43, 47 to secure the end flaps in the closed configuration of the end 7.
As shown in FIG. 9, the lower article protection feature 11, 11A, 11B is spaced apart from the bottom panel 15 by a first distance D1 and the upper article protection feature 11, 11A, 11B is spaced apart from the bottom panel by a second distance D2. In one embodiment, the second distance D2 is greater than the first distance D1. The distances D1 can be selected so that the lower article protection feature 11 contacts the container C near a bottom portion B of the container. The distance D2 can be selected so that the upper article protection feature 11 contacts the container C near the shoulder S of the container. The positioning of the upper and lower article protection features 11 provides a respective container C with two contact points with the shock absorbing features at the end 7 of the carton 5 so that each respective container C is stabilized and cushioned against impacts occurring at the end of the carton. The article protection features could be otherwise arranged and positioned without departing from the disclosure.
FIG. 4A shows an alternative configuration of the end 7 wherein the side end flap 37 has two notches 141 instead of the indentations 81. The notches 141 allow the indentations 81 near the edge of the exterior surface of the side end flap 43 to cooperate with the middle indentations 83 on the bottom end flap 33 to form a pocket similar to the pocket 135 shown in FIG. 9, but with the pocket 135 being wider as a result of the intervening layer of material from the side end flap 37.
FIGS. 5A and 5B show an alternative configuration of the end 7 wherein the bottom end flap 33 is modified from the bottom end flap shown in FIG. 4. In the embodiment of FIGS. 5A and 5B, the indentations 83 on the interior surface near the peripheral edge of the bottom end flap 33 of FIG. 4 are replaced by a deformation 149 at the peripheral edge of the bottom end flap 33. The deformation 149 includes a series of indentations 151 on the interior surface of the bottom end flap 33 that are adjacent to a respective indentation on the exterior surface 153 of the bottom end flap. The indentations 151 on the interior surface of the bottom end flap 33 communicate with the upper indentations 81 on the side end flaps 37, 43 to form a respective pocket or series of pockets. Alternatively, the upper indentations 81 on the side end flaps 37, 43 could be replaced with a deformation similar to the deformation 149 of the bottom end flap, or any other configuration that is suitable for creating a pocket or series of pockets that form the article protection features.
FIG. 5C shows an alternative configuration of the end 7 wherein the side end flaps 37, 43 and bottom end flap 33 are modified from the flaps shown in FIG. 4. In the embodiment of FIG. 5C, the bottom end flap 33 has indentations 155 on the interior surface near the peripheral edge of the bottom end flap that are modified from the embodiment of FIG. 4. Further, the side end flaps 37, 43 each have upper indentations 157 that are modified from the embodiment of FIGS. 4 and 5. Both groups of indentations 155, 157 are elongated from the embodiment of FIGS. 4 and 5, and the indentations 155 on the bottom end flap are each sized to extend between two adjacent indentations 157 on the side end flaps 37, 43. The indentations 155 are in communication with multiple indentations 157 so that the pocket faulted by the cooperating indentations forms an article protection feature 11 that is elongated and contacts two adjacent articles C. The elongated article protection feature can be filled with shock absorbing material in a similar manner as described above for the first embodiment. Alternative, the lower indentations on the interior surface of the bottom end flap 33 and the lower indentations 81 on the side end flaps 37, 43 could be similar to the indentations 155, 157 without departing from the disclosure.
In the first embodiment, the loaded and closed carton 5 of FIG. 8 is further processed so that the article protection flaps 13 are activated. The article protection flaps 13 are foldably connected to the bottom panel 15 and moveable between a first position (FIG. 2) that is substantially parallel to the bottom panel and a second position (FIG. 8A) wherein the article protection flaps are folded relative to the bottom panel. In one embodiment, the article protection flaps 13 are raised or activated to the position of FIG. 8A, and the article protection flaps have features for preventing the folding of the article protection flaps from the second position back to the first position. FIG. 8A illustrates an outermost row of containers C removed and the end flaps 33, 37, 43, 47 at the end 7 open so that the article protection flaps 13 are visible. It is understood that the article protection flaps 13 will be activated to the second position (FIG. 8A) after the ends 7, 9 of the carton 5 have been closed. Alternatively, the article protection flaps 13 could be activated prior to closing one or both of the ends 7, 9 of the carton 5 without departing from the disclosure.
The article protection flaps 13 can be activated by various forming apparatus, some of which will be described below in further detail, or any other suitable method. The activation of a single article protection flap 13 will be described in detail herein, but it is understood that the other article protection flaps can be activated in a similar or different manner without departing from the disclosure. FIGS. 10A and 10B are enlarged portions of the interior surface of the bottom panel 15, with FIG. 10A showing the interior surface of the bottom panel prior to activation of the article protection flap 13, and FIG. 10B showing the interior of the bottom panel after activation of the article protection flap. In one embodiment, a finger or other portion of an apparatus for forming the carton 5 presses against the central portion 125 (FIG. 10A) of the article protection flap 13 to initiate separation of the article protection flap from the bottom panel 13 along the cut 103. As shown in FIGS. 8A, 10A, and 10C, the article protection flap 13 is pivoted upward relative to the bottom panel 15 at the fold line 101 in the direction of arrow A1 to create an opening 161 in the bottom panel. As the article protection flap 13 is activated, the first portion 121 and the second portion 123 are folded relative to each other. In one embodiment, the first portion 121 and the second portion 123 of the article protection flap are folded inwardly relative to each other and relative to the central portion 125. As such, the article protection flap 13 provides two layers of material (e.g., the inwardly folded first portion 121 and second portion 123) between adjacent containers C in the carton 5.
In one embodiment, the article protection flaps 13 are upwardly folded to the second (raised) position shown in FIG. 8A, or the article protection flaps can be upwardly folded to a second (raised) position shown in FIG. 10C. In one embodiment, the upwardly folding of the article protection flaps 13 causes the containers C in the carton 5 to move to accommodate the space required for the article protection flaps in the second position with the first portion 121 and second portion 123 folded relative to each other. The movement of the containers C when the article protection flaps 13 are upwardly folded and located between adjacent containers, tightens the packing of the containers in the carton 5 so that the movement of the containers is limited by the positioning of the article protection flaps 13 and the respective end flaps 33, 37, 43, 47 and 35, 39, 45, 49 at the closed ends 7, 9 of the carton. The article protection flaps 13 are pressed against two adjacent containers C to initiate movement of the containers and provide the tightening feature of the article protection flaps.
In one embodiment, the configuration of the first portion 121 and the second portion 123 prevents the article protection flap 13 from being downwardly folded from the second or raised position of FIG. 8 to the first or lowered position of FIG. 2. As shown in FIG. 10B, when the first portion 121 and the second portion 123 of the article protection flap 13 are inwardly folded relative to each other, the first and second portions extend beyond the edge 163 of the opening 161 created at the third portion 113 of the cut 103. In one embodiment, an edge 165 (FIG. 10C) of the first portion 121 of the article protection flap 13, formed by the rounded corner 109 of the cut 103 extends beyond the edge 163 of the opening 161. Also, an edge 167 (FIG. 10C) of the second portion 123 of the article protection flap 13 formed by the rounded corner 111 of the cut 103 extends beyond the edge 163 of the opening 161. The positioning of the distal portions 166, 168 of the first portion 121 and second portion 123, including the edges 165, 167 of the article protection flap 13, relative to the edge 163 of the opening 161 prevents the article protection flaps 13 from being downwardly folded to the first position wherein the article protection flaps are substantially parallel to the bottom panel 15. As such, once the article protection flaps 13 are raised to the second position and positioned between adjacent containers C, the article protection flaps stay in the upwardly folded position providing cushioning and protection between adjacent containers. The article protection flaps 13 could be otherwise shaped, arranged, and/or configured to have other features for preventing the article protection flaps from returning to the first or lowered position without departing from the disclosure.
FIGS. 10D-10F show an article protection flap 13 having alternative features. In the embodiment of FIGS. 10D-10F, the first portion 121 and the second portion 123 of the article protection flap 13 each have a respective deformation 171, 173 in the form of an indentation on the exterior surface of the article protection flap 13. The article protection flap 13 of the embodiment of FIGS. 10D-10F is activated in a similar manner as described above for the previous embodiment, wherein the first portion 121 is folded relative to the second portion 123 of the article protection flap. As shown in FIG. 10F, the indentations 171, 173 of the respective first and second portions 121, 123 cooperate to form a space 175 between the first portion and the second portion of the article protection flaps 13. The space 175 can comprise shock absorbing material, such as the shock absorbing material 139 discussed above for the article protection features 11, or any other suitable material. The space 175 between the first and second portions 121, 123 of the article protection flap 13 of FIG. 10F provides enhanced article protection and reduction of breakage of the containers C. The deformations 171, 173 could be otherwise shaped, arranged, configured, positioned, and/or omitted without departing from the scope of the disclosure.
One embodiment of a system 181 for activating the article protection flaps 13 is illustrated in FIGS. 11 and 12. In one embodiment, the cartons 5, having containers C loaded and the ends 7, 9 closed, are conveyed via an inlet conveyor 183 to a first or inlet end 185 of the system 181. However, the system 181 could also be used to activate the article protection flaps 13 of the cartons 5 prior to closing one or both of the ends 7, 9. The system 181 comprises a sled 187 that receives a carton 5 from the inlet conveyor 183 such that the bottom panel 15 of the carton is in contact with the top surface 189 of the sled. The sled 187 is operatively attached to a cam track array or section 191 that includes a series of spaced rails 193 (FIG. 12) with a series of cam tracks 195 mounted therebetween. The sled 187 comprises a series of actuating fingers 197 pivotally mounted to the sled and moveable through a respective slot 199 in the top surface 189 of the sled. The actuating fingers 197 have a lower portion that engages a respective cam track 195 such that the actuating finger 197 is raised or lowered in the slot 199 by the slope of the cam track. As the sled 187 with carton 5 mounted on the top surface 189 moves in the direction of arrow A2 (FIG. 11), the fingers 197 are raised and lowered in the slots 199 to activate the article protection flaps 13 in the bottom panel 15. After the article protection flaps 13 are activated by the system 181, the carton 5 exits an exiting end 201 of the system for further handling and packaging. The system 180 could be alternatively shaped, arranged, and/or configured without departing from the disclosure.
FIG. 13 illustrates an alternative embodiment of a system 207 for activating the article protection flaps 13 of the carton 5. The system 207 comprises a cassette 209 that can be mounted along the path of travel of the carton 5 in a packaging machine. In one embodiment, the cassette 209 comprises a series of actuating fingers 211 mounted to a chain 213. The fingers 211 move along a cam track 215 that receives a portion of the fingers 211 as the fingers are conveyed around the cassette. As the fingers 211 move along the cam track 215, the fingers can be positioned between non-engaging and engaging positions for selectively activating the article protection flaps 13 of the carton 5. The system 207 could be alternatively shaped, arranged, and/or configured without departing from the disclosure.
FIG. 14 shows features of an alternative embodiment of a system 221 for activating the article protection flaps 13 of the carton 5.

FIGS. 31A-31C illustrate various features of a blank 1103 for forming a carton 1105 of an alternative embodiment having similar features as the previous embodiments of the disclosure. Accordingly, like or similar features will be indicated with like or similar reference numbers. The blank 1103 is a single panel for supporting the plurality of containers C. The blank 1103 comprises article protection flaps 1113 similar to the article protection flaps 13 of the earlier embodiments. The carton 1105 is formed by placing the plurality of containers C on the blank 1103 and then activating the article protection flaps 1113 by moving the article protection flaps from the first position that is substantially parallel to the blank 1103 to the second position wherein the article protection flaps are folded relative to the panel of the blank. In one embodiment, the carton 1105 can be further assembly by applying an overwrap of shrink-wrap (e.g., shrinkable polymer film) or other packaging material M so that the containers are securely attached to the blank 1103. In the embodiment of FIGS. 31A-31C the blank 1103 is a bottom panel, but the blank could be otherwise shaped, arranged, or configured without departing from the disclosure.
In an alternative embodiment, blank 1103 and articles C with activated article protection flaps 113 can be positioned relative to a construct to at least partially enclose the blank and the at least two articles. In one embodiment the construct can be a sleeve similar to the sleeve 131 of FIG. 2. Further the construct can have at least one open end, such as the ends 7, 9 that can be closed by respective end flaps. The blank 1103 and articles C can be positioned in an interior of the sleeve prior to closing both the ends 7, 9, or one of the ends can be closed prior to positioning the blank and articles. Alternatively, the construct could be a lid that fits over the tops of the articles C, and the lid could have one or more side panels extending down from a top panel.
FIGS. 32A-32C illustrate various features of a blank 1203 for forming a carton 1205 of an alternative embodiment having similar features as the previous embodiments of the disclosure. Accordingly, like or similar features will be indicated with like or similar reference numbers. The blank 1203 comprises a bottom panel 1214 and four side panels 1218, 1220, 1222, 1224 for forming a tray 1226 (FIG. 32B) having an interior space for holding the container C. The blank 1203 comprises article protection flaps 1213 similar to the article protection flaps 13 of the earlier embodiments. The carton 1205 is formed by placing the plurality of containers C on the bottom panel 1214 of the blank 1203 and upwardly folding the side panels 1218, 1220, 1222, 1224 to form the tray 1226. The article protection flaps 1213 are activated by moving the article protection flaps from the first position that is substantially parallel to the bottom panel 1214 to the second position wherein the article protection flaps are folded relative to the bottom panel of the blank 1203. In one embodiment, the carton 1205 can be further assembled by applying an overwrap of shrink-wrap (e.g., shrinkable polymer film) or other packaging material M so that the containers are securely attached to the tray 1226. In the embodiment of FIGS. 32A-32C the blank 1203 is configured for forming the tray 1226, but the blank could be otherwise shaped, arranged, or configured without departing from the disclosure.
FIGS. 33A-33C illustrate various features of a blank 1303 for forming a carton 1305 of an alternative embodiment having similar features as the previous embodiments of the disclosure. Accordingly, like or similar features will be indicated with like or similar reference numbers. The blank 1303 is generally similar to the blank 3 of the first embodiment in that the blank of FIGS. 33A-33C comprises a bottom panel 1315 and a first side panel 1317, a second side panel 1321, and a top panel 1325. The blank 1303 comprises article protection flaps 1313 similar to the article protection flaps 13 of the earlier embodiments. The carton 1305 is formed by placing the plurality of containers C on the bottom panel 1214 of the blank 1203 and upwardly folding the side panels 1317, 1321 around the containers on the bottom panel to partially form the carton as shown in FIG. 33B. Next, the top panel 1325 is downwardly folded to close the interior of the carton 1305 and the ends 1307, 1309 are closed by closing respective end flaps 1333, 1337, 1343, 1347 and 1335, 1339, 1345, and 1349. The article protection flaps 1313 are activated by moving the article protection flaps from the first position that is substantially parallel to the bottom panel 1315 to the second position wherein the article protection flaps are folded relative to the bottom panel 1315 of the blank 1303. The blank 1303 could be otherwise shaped, arranged, or configured without departing from the disclosure.
The cartons of any of the illustrated or non-illustrated embodiments of the disclosure could have other features (e.g., dispenser features, handle features, reinforcement features, etc.) without departing from the disclosure. Also, the cartons could be otherwise shaped, arranged, or configured and the cartons could be configured to hold articles other than beverage containers C without departing from the disclosure.
In general, the blanks of any of the illustrated or non-illustrated embodiments 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 of 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.
