DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

)018] The present disclosure generally relates to cartons that contain articles such as containers.

The articles can be used for packaging food and beverage products, for example. The articles can be made from materials suitable in composition for packaging the particular food or beverage item, and the materials include, but are not limited to, paperboard; cardboard; aluminum and/or other metals; glass; plastics such as PET₅ LDPE, LLDPE, HDPE, PP, PS, PVC, EVOH, and Nylon; and the like, or any combination thereof.

0O19] 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 food product containers (e.g., paperboard boxes) 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.

D020] Fig. 1 is a plan view of the exterior side 102 of a blank, generally indicated at 100, used to form a carton 200 (Fig. 6) according to the exemplary embodiment of the disclosure. The carton 200 can be used to house a plurality of articles such as containers C (Fig. 4). In one embodiment, the carton 200 is of the type commonly referred to as a "Biers" or "Biers" carton or tray. The carton 200 has an erected and open shape shown in Fig. 2 and a flattened shape 201 shown in Fig. 3. In the illustrated embodiment, the carton 200 is sized to house thirty-six parallelpiped containers C in a 3x6x2 arrangement, but the carton 200 may be sized and shaped to hold containers of a different or same quantity in one or more layers and/or in different row/column arrangements (e.g., 1x6, 3x5, 2x6x2, 3x4x2, 2x9, 2x6, 3x4, etc.). The carton 200 may further be alternatively sized and shaped to hold containers of a different shape.

0021] The blank 100 has a longitudinal axis Ll and a lateral or transverse axis L2. In the illustrated embodiment, the blank 100 comprises a bottom panel 110 foldably connected to a first side panel 120 at a first lateral line 121, a top panel 130 foldably connected to the first side panel 120 at a second lateral fold line 131, and a second side panel 140 foldably connected to the bottom panel 110 at a third lateral fold line 141.

9022] The bottom panel 110 is foldably connected to a first bottom end flap 112 and a second bottom end flap 114. The first side panel 120 is foldably connected to a first side end flap 122 and a second side end flap 124. The top panel 130 is foldably connected to a first top end flap 132, a second top end flap 134, and an extension flap 136. The extension flap 136 is connected to the top flap 130 by a transverse tear line 133 and can include a finger aperture 138 defined by the tear line 133 and an arcuate edge 139. The second side panel 140 is foldably connected to a first side end flap 142 and a second side end flap 144. The second side panel 140 can include a recess 146 shaped to provide clearance for a finger accessing the finger aperture 138 when the carton 200 is fully assembled in the shipping state (Fig. 6).

)023] In the illustrated embodiment, the first top and bottom end flaps 132, 112 and first side end flaps 122, 142 extend along a first marginal area of the blank 100, and are foldably connected at a first longitudinal fold line 162 that extends along the length of the blank. The second top and bottom end flaps 134, 114 and second side end flaps 124, 144 extend along a second marginal area of the blank 100, and are foldably connected at a second longitudinal fold line 164 that also extends along the length of the blank. The longitudinal fold lines 162, 164 may be, for example, substantially straight, or offset at one or more locations to account for blank thickness or for other factors. When the blank 100 is erected into the carton 200, the first top and bottom end flaps 132, 112 and first side end flaps 122, 142 close a first end 151 of the carton, and the second top and bottom end flaps 134, 114 and second side end flaps 124, 144 close a second end 153 of the carton. In accordance with an alternative embodiment of the present disclosure, different flap arrangements can be used for closing the ends 151, 153 of the carton 200. 0024] In the illustrated embodiment, the first and second bottom end flaps 112, 114 each comprise an oblique edge 170, a longitudinal edge 171, and a generally transverse edge 172 that is generally aligned with the transverse fold line 141. The first and second bottom end flaps 112, 114 each further include a proximal portion 175 connected to a distal portion 177 at an oblique fold line 174 extending from the oblique edge 170 to a clearance notch 176. The clearance notch 176 reduces excess material at the comers of the carton 200 for easier folding into the flattened state 201 shown in Fig. 3. In the illustrated embodiment, the transverse edge 172 extends from an end of the longitudinal edge 171 to the clearance notch 176. The first and second bottom end flaps 112, 114 could be otherwise shaped, arranged, and/or configured.

9025J In the illustrated embodiment, the first and second side end flaps 122, 124 each comprise an oblique edge 180, a longitudinal edge 181, and a generally transverse edge 182 that is generally aligned with the transverse fold line 131. The first and second side end flaps 122, 124 each further include a proximal portion 185 connected to a distal portion 187 at an oblique fold line 184 extending from the oblique edge 180 to a clearance notch 186. The clearance notch 186 reduces excess material at the corners of the carton 200 for easier folding into the flattened state 201 shown in Fig. 3. In the illustrated embodiment, the transverse edge 182 extends from an end of the longitudinal edge 181 to the clearance notch 186. In the illustrated embodiment, the first and second end flaps 122, 124 include a lateral edge 183 extending from the longitudinal fold line 166 to the oblique edge 180. The first and second side end flaps 122, 124 could be otherwise shaped, arranged, and/or configured.

)026] In one embodiment, the first and second side end flaps 142, 144 are each defined, in part, by an oblique edge 190 and a drag edge 191. The first and second top end flaps 132, 134 are each defined, in part, by an oblique edge 192 and a drag edge 193. The side end flaps 142, 144 and/or the top end flaps 132, 134 could be otherwise shaped, arranged, and/or configured.

)027] In accordance with the exemplary embodiment, the blank 100 can be erected into the carton 200 by folding the second side panel 140 upward about fold line 141 and folding the first side end flap 142 and the first bottom end flap 112 upward about the longitudinal fold line 162. The first bottom end flap 112 is folded such that it is at least partially in face-to-face contact with the first side end flap 142 such that the transverse edge 172 is generally aligned in an overlapping relationship with the portion of the longitudinal fold line 162 joining the second side panel 140 and the first side end flap 142. In the illustrated embodiment, the oblique edge 170 is aligned with the oblique edge 190 to form a generally straight edge. A portion of the first side end flap 142 can be glued to the distal portion 177 of the first bottom end flap 112 to form the first end panel 202 (Fig. 2). It should be noted that the fold line 174 should have an angle Al (Fig. 1), relative to the fold line 162, sufficient to allow the first bottom end flap 112 to be folded inward while attached to a portion of the first side end flap 142 when collapsing the carton 200 into the flattened state 201 (Fig. 3). For example, a sufficient angle Al may be approximately 45° with respect to the longitudinal fold line 162.

9028] In the illustrated embodiment, the second bottom end flap 114 and the second side end flap 144 are folded about the longitudinal fold line 164 and are at least partially overlapped with a portion of the second side end flap 144 glued to the distal portion 177 of the second bottom end flap 114 to form the second end panel 204 (Fig. 2) in a similar manner as the first bottom end flap 112 and first side end flap 142. The bottom end flaps 112, 114 form respective first end flaps of the end panels 202, 204, and the side end flaps 142, 144 form respective second end flaps of the end panels 202, 204. The first side panel 140, the bottom panel 110, and the end panels 202, 204 form a tray portion 155 of the container (Fig. 2).

D029] In one embodiment, the top panel 130 is folded upward about fold line 131, and the first side end flap 122 and the first top end flap 132 are folded upward about the longitudinal fold line 162. The first side end flap 122 is folded such that it is at least partially in face-to-face contact with the first top end flap 132 such that the transverse edge 182 is generally aligned in an overlapping relationship with the portion of the longitudinal fold line 162 connecting the first top end flap 132 to the top panel 130. In the illustrated embodiment, the oblique edge 180 is aligned with the oblique edge 192 to form a generally straight edge. The distal portion 187 of the first side end flap 122 is glued to a portion of the first top end flap 132 to form a third end panel 206 (Fig. 2). It should be noted that the fold line 184 should have an angle A2 (Fig. 1), relative to the longitudinal fold line 162 sufficient to allow the first side end flap 122 to be folded inward while attached to a portion of the first top end flap 132 when collapsing the carton 200 into the flattened state 201 (Fig. 3). For example, a sufficient angle A2 may be approximately 45° with respect to the longitudinal fold line 162. 3030] In the illustrated embodiment, the second top end flap 134 and the second side end flap

124 are folded about the longitudinal fold line 164 and are at least partially overlapped with a portion of the second top end flap 134 glued to the distal portion 187 of the second side end flap 124 to form the fourth end panel 208 (Fig. 2) in a similar manner as the first top end flap 132 and first side end flap 122. The side end flaps 122, 124 form respective first end flaps of the end panels 206, 208, and the top end flaps 132, 134 form respective second end flaps of the end panels 206, 208. The second side panel 120, the top panel 130, and the end panels 206, 208 form atop portion 157 of the container (Fig. 2).

D031] The resulting carton 200 of the illustrated embodiment is erected and ready for loading as shown in Fig. 2. However, the carton 200 can be collapsed into a flattened state 201 shown in Fig. 3 by folding the first and second end panels 202, 204 inward along the respective longitudinal fold lines 162, 164 and the oblique fold lines 174, and folding the third and forth end panels 206, 208 inward along the respective longitudinal fold lines 152, 164 and the oblique fold lines 184. Upon folding the end panels 202, 204, 206, 208 inward, the second side panel 140 pivots downwardly about the transverse fold line 141 toward the bottom panel 110, and the top panel 130 pivots downwardly about the transverse fold line 131 toward the first side panel 120. In the collapsed state 201, the second side panel 140 overlaps and is in face-to-face contact with the inwardly folded end panels 202, 204 and the bottom panel 110. In the flattened state 201, the top panel 130 overlaps and is in face-to-face contact with the inwardly folded end panels 206, 208, the first side panel 120, and the bottom panel 110. Further, for each bottom end flap 112, 114 the distal portion 177 is in face-to-face contact with the respective proximal portion 175, and for each side end flap 122, 124 the distal portion 187 is in face-to-face contact with the proximal portion 185. As shown in Fig. 3, the extension flap 136 connected to the top panel 130 overlaps and is in face-to-face contact with a marginal portion of the second side panel 140.

0032] In the illustrated embodiment, the respective drag edges 191, 193 of the first and second side end flaps 142, 144, and the first and second top end flaps 132, 134 have only slight tapers. This causes the end flaps to drag against the bottom panel 110 or the first side panel 120 and thus resist collapsing. Thereby, the carton 200 is less likely to collapse without a deliberate action by the user. The carton 200 lays generally flat in the flattened state 201, shown in Fig. 3, which allows the carton 200 to be efficiently stored or shipped prior to loading the carton with the containers C.

0033] The carton 200 may be opened from the flat configuration 201 of Fig. 3 by pivoting the top panel 130 and the second side panel 140 upward and away from the respective first side panel 120 and the bottom panel 110, which straightens the first end panel 202, the second end panel 204, the third end panel 206, and the fourth end panel 208 to the position generally shown in Fig. 2. As shown in Fig. 4, the containers C may then be placed in the carton 200. In the illustrated embodiment, the containers C are loaded into the carton 200 such that the printed front faces of the containers are directed upward with the bottoms of the containers C contacting the second side panel 140. This allows the containers C to be properly displayed when the container 200 is converted to a display tray 300 as described below. The loaded carton 200 is closed for shipping, storage, or both by first folding about the transverse line 121 (Fig. 5) and then gluing the extension flap 136 to the marginal portion of the second side panel 140 (Fig. 6). Alternatively, the container 200 could be loaded and closed by other folding or positioning steps.

1)034] With reference to Figs. 7-9, the carton 200 can be converted to a display tray 300. A user grasps the top panel 130 using fmger aperture 138 and recess 146 and tears the top panel 130 away from the extension flap 136 along tear line 133 and pivots the top panel 130, the first side panel 120, and the third and fourth end panels 206, 208 about the line 121. The user then tears the first side panel 120 away from the bottom panel 110 along the line 121, which may be a tear line, as shown in Fig. 8. The remaining display tray 300 is set up with the second side panel 140 forming a bottom of the display tray that can be supported on a surface S (e.g., shelf or counter). In one embodiment, the display tray 300 has an open front that displays the front faces of the containers C in an upright position as shown in Figs. 8 and 9. The display tray has a back formed by the bottom panel 110 of the container 200 and two sides formed by the end panels 202, 204.

0035] Alternative folding and loading sequences to that described above may be used to erect carton 200 and convert it to display tray 300 without departing from the scope of the disclosure. Further, the blank 100 can be otherwise configured to have multiple top panels, multiple bottom panels, multiple side panels, or combinations thereof without departing from the scope of this disclosure. Even further, the carton 200 may be a wrap-around type carton, with the blank 100 including locking features that can include primary and secondary locking features as is known in the art.

The blank according to the present disclosure can be, for example, formed from coated paperboard and similar materials. For example, the interior and/or exterior sides of the blank can be coated with a clay coating. The clay coating may then be printed over with product, advertising, price coding, and other information or images. The blank may then be coated with a varnish to protect any information printed on the blank. The blank may also be coated with, for example, a moisture barrier layer, on either or both sides of the blank. In accordance with the above-described embodiments, the blank may be constructed of paperboard of a caliper such that it is heavier and more rigid than ordinary paper. The blank can also be constructed of other materials, such as cardboard, hard paper, or any other material having properties suitable for enabling the carton to function at least generally as described herein. The blank 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 may 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.

9039] 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.

0040] The foregoing description of the disclosure illustrates and describes various embodiments of the present disclosure. 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 without departing from the scope of the disclosure.
