Further, the various features of the drawings discussed below are not necessarily drawn to scale. Dimensions of various features and elements in the drawings may be expanded or reduced to more clearly illustrate the embodiments of the disclosure.
Corresponding parts are designated by corresponding reference numbers throughout the drawings.
The present disclosure generally relates to cartons that contain articles such as containers, bottles, cans, etc., and handle reinforcement features of such cartons. The articles can be used for containing 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 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; and the like, or any combination thereof.
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.
In one embodiment, the carton 5 has first and second ends 7, 9 each having article protection features 11, 13 that project into the interior of the carton to contact respective containers. In one embodiment, the article protection features 11, 13 project towards the interior of the carton from the end 7, 9 and are located between respective rows of the containers C. The carton has features for forming a handle 14 in a respective end 7, 9 of the carton, but the carton could be otherwise shaped, arranged, and/or configured without departing form the disclosure.
The blank 3 has a longitudinal axis L1 and a lateral axis L2. A bottom panel 15 is 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 second side panel 21 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. 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.
The blank 3 has a lateral fold line 65 extending through side end flap 37 and side end flap 39 so that each of these flaps may be folded along the fold line 65 to have an upper portion that tapers inward relative to a lower portion. A lateral fold line 67 extends through the side end flap 43 and side end flap 45 so that each of these flaps may be folded along the fold line 67 to have an upper portion that tapers inward relative to a lower portion. The blank 3 includes four diamond corners 71 formed by the portion of the fold line 61, 63 connecting a respective side panel 17, 21 to a respective end flap 37, 39, 43, 45, a first fold line 73 in a respective side panel, and a second fold line 75 in a respective side panel. The fold lines 73, 75 of the diamond corners 71 are shaped, arranged, and positioned to create a corner of the carton 5 that is in a tight fit with the container C adjacent the corner. In one embodiment, the fold lines 65, 67 allow the ends 7, 9 of the carton 5 to angle inward toward the interior of the carton 5. The diamond corners 71 could be otherwise shaped, arranged, and/or configured without departing from the disclosure.
In one embodiment, the top panel 25 of the blank 3 can have a length less than a respective length of the bottom panel 15. In the illustrated embodiment, the shorter length of the top panel 25 as compared to the bottom panel 15 causes both ends 7, 9 of the carton 5 to be shaped to contact both the top and bottom of the containers C housed in the carton to restrain the movement of the containers in the carton. The bottom panel 15 and/or top panel 25 can be otherwise shaped, arranged, and/or configured without departing from the disclosure. For example, the bottom panel 15 and top panel 25 could have a different width, and the same length, or both the same width and length without departing from the disclosure.
The blank 3 comprises features that form the handle 14 of the carton 5. In one embodiment the features include a handle flap 81 foldably connected to a respective top end flap 47, 49 at a curved fold line 83. In one embodiment, the handle flap 81 is formed by a cut or tear line 85 extending from respective ends of the fold line 83. The handle flap 81 could be otherwise shaped, arranged, and/or configured without departing from the disclosure.
The handle features of the blank 3 further comprise a notch 105 in a respective end flap 43, 45 attached to the second side panel 21 and a notch 107 in a respective end flap 37, 39 attached to the first side panel 17. The handle features comprise a portion 109 of the end flap 43, 45 above or adjacent the notch 105 and a portion 113 of the end flap 37, 39 above or adjacent the notch 107. The handle features could be otherwise shaped, arranged, and/or configured, and could have other reinforcement features without departing from the disclosure. Further, the handle 14 could be omitted without departing from the disclosure.
In the illustrated embodiment, the article protection features 11 of the blank 3 are formed in respective end flaps 43, 45 and include an article retention actuator flap 115 foldably connected to a respective portion 109 of the end flaps 43, 45 at two spaced apart, oblique fold lines 117. The article retention actuator flap 115 may be termed an actuator portion in some embodiments. In one embodiment, a curved cut 119 extends between the oblique fold lines 117 to form an article retention tab 121. A curved cut 123 is spaced apart from the curved cut 119 and forms a line of weakening that foldably connects the article retention tab 121 to the article retention actuator flap 115. The article retention tab 121 is separated from a respective top end flap 47, 49 by an oblique cut 125. The article protection features 11 could be otherwise shaped, arranged, and/or configured without departing from the disclosure.
In one embodiment, the article protection features 13 of the blank 3 are formed in respective end flaps 37, 39 and include an article retention actuator flap 135 foldably connected to a respective portion 113 of the end flaps 37, 39 at two spaced apart, oblique fold lines 137. The article retention actuator flap 135 may be termed an actuator portion in some embodiments. In one embodiment, a curved cut 139 extends between the oblique fold lines 137 to form an article retention tab 141. A curved cut 143 is spaced apart from the curved cut 139 and forms a line of weakening that foldably connects the article retention tab 141 to the article retention actuator flap 135. The article protection features 13 could be otherwise shaped, arranged, and/or configured without departing from the disclosure.

As shown in
The cartons 5 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 5 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 blank 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 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.
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. Additionally, the disclosure shows and describes only selected embodiments, but various other combinations, modifications, and environments are within the scope of the disclosure 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.
