DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS
The present disclosure generally relates to constructs, sleeves, cartons, or the like, and packages for containing, holding, and displaying articles such as beverage containers (e.g., bottles, cans, jars, etc.). 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, plastics such as PET, LDPE, LLDPE, HDPE, PP, PS, PVC, EVOH, and Nylon; and the like; aluminum and/or other metals; glass; or any combination thereof.
Packages or cartons shown in the present disclosure can accommodate containers of numerous different shapes. For the purpose of illustration and not for the purpose of limiting the scope of the invention, the following detailed description describes beverage containers (e.g., plastic containers) at least partially disposed within the carton embodiments. In this specification, the terms “lower,” “bottom,” “upper” and “top” indicate orientations determined in relation to fully erected cartons.
FIG. 1 is a plan view of a blank, generally indicated at 3, used to form a construct (e.g., a sleeve or a partial sleeve) that is referred to as a carton 5 (FIG. 2) according to a first embodiment. The carton 5 can be used to hold or contain a plurality of articles such as containers C (FIG. 2). The carton 5 and the containers C may be secured together by an overwrap of shrink-wrap (e.g., shrinkable polymer film) or other packaging material M (FIG. 2) so that the carton 5, containers C, and packaging material form a package 6. The carton 5 holds the containers and provides increased rigidity to the package 6 and stabilizes the containers C so that the package may be more easily handled.
In the illustrated embodiments, the containers C are bottles containing a soft drink or other beverage but the containers may contain other beverage or food products. In the illustrated embodiments (e.g., embodiment of FIGS. 1-3), the carton 5 is sized to house fifteen containers C in a single layer in a 3×5 arrangement, but 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, 3×6, 2×6×2, 3×4×2, 2×9, 2×6, 3×4, etc.). In the embodiment of FIGS. 1-3, the carton 5 includes a first and a second handle, generally indicated at 11, 13, for grasping and carrying the carton. As will be discussed below in more detail, the handles 11, 13 are formed from various features in the blank 3.
The blank 3 has a longitudinal axis L1 and a lateral axis L2. In the illustrated embodiment, the blank 3 comprises a central panel 10 foldably connected to a first side panel 20 at a first lateral fold line 21, a front panel 30 foldably connected to the central panel 10 at a first longitudinal fold line 31, a second side panel 40 foldably connected to the central panel 10 at a second lateral fold line 41, and a back panel 50 foldably connected to the central panel 10 at a second longitudinal fold line 51.
In the embodiment of FIGS. 1-3, the central panel includes fifteen openings 12 arranged in a 3×5 pattern to correspond with the location of the containers C. Oblique fold lines 15 are arranged in the shape of a diamond between adjacent openings 12 in the three rows. Lateral fold lines 17 respectively connect the diamond-shaped fold lines 15 of adjacent rows. The oblique fold lines 15 and lateral fold lines 17 allow the central panel 10 to flex when the carton 5 is placed over the top of the containers C. The central panel 10 could be free from fold lines or could have fold lines that are otherwise shaped and arranged without departing from the invention. Further, the central panel 10 may include tear lines or other features that form a dispenser for allowing removal of the containers C from the carton 5.
The first side panel 20 is located at a first longitudinal end of the central panel 10 and includes a first panel 22 foldably connected to the central panel 10 and a second panel 24 foldably connected to the first panel at a lateral fold line 23. The first panel 22 includes an elongate handle flap 26 foldably connected to the first panel 22 at a lateral fold line 27. As shown in FIG. 1, the handle flap 26 is obstructing a handle opening in the first panel 22, and the handle flap 26 can be pivoted to expose the handle opening that it obstructs. The second panel 24 has an elongate opening 29 shaped to correspond with the handle flap 26. A reinforcement flap 32 is foldably connected to the second panel 24 at a lateral fold line 35. The reinforcement flap 32 includes three semicircular notches 37 in a lateral edge 39 of the flap.
In the embodiment of FIGS. 1-3, the second side panel 40 is located at a second longitudinal end of the central panel 10 and is generally a mirror image of the first side panel 20. Accordingly, like reference numbers have been used to designate similar or identical components (e.g., panels, flaps, fold lines, openings, etc.) that comprise the first and second side panels 20, 40. The first and second side panels 20, 40 may be otherwise shaped and/or arranged without departing from the invention.
In the embodiment of FIGS. 1-3, a reinforcement insert 60 is shown adjacent to the back panel 50. The reinforcement insert 60 is separate from the blank 3 and is used for overlaying at least a portion of the inner surface of the central panel 10 to reinforce the carton 5. The reinforcement insert 60 includes three circular openings 62 and two semicircular notches 64 at respective longitudinal ends of the reinforcement insert. The reinforcement insert 60 includes oblique fold lines 66 arranged to form diamond-shaped patterns between adjacent notches 64 and openings 62 in the insert. Lateral fold lines 67 extend from respective points of the diamond-shaped fold lines 66.
In the embodiment of FIGS. 1-3, the first handle 11 is formed in the first side panel 20 and the second handle 13 is formed in the second side panel 40 and has identical components as the first handle. As shown in FIG. 1, the features that form the first and second handles 11, 13 of the carton 5 include the elongate handle flaps 26 formed in the first panels 22 and the openings 29 formed in the second panels 24. The handles 11, 13 may include other features or the illustrated features may be otherwise shaped and/or arranged without departing from the invention.
The blank 3 is formed into the carton 5 by folding the second panels 24 of the side panels 20, 40 at lateral fold lines 23 so that respective second panels underlay the first panels 22 and respective reinforcement flaps 32 underlay a portion of the central panel 10. In the assembled position of the carton 5, the second panels 24 are in face-to-face contact with a respective one of the first panels 22, and the reinforcement flaps 32 are in respective face-to-face contact with a portion of the inner surface of the central panel 10. The side panels 20, 40 are downwardly folded relative to the central panel 10 to form a space for receiving containers C. The elongate handle openings 29 are aligned with the elongate handle flaps 26 and the notches 37 of each reinforcement flap 32 are aligned with respective openings 12 of the end columns of the openings. The reinforcement flaps 32 can be secured to the underside of the central panel 10 by adhesive (e.g., glue) placed on respective reinforcement flaps. The front panel 30 is folded downward at fold line 31 and the back panel 50 is folded downward at fold line 51.
The reinforcement panel 60 can be adhesively attached to a portion of the underside of the central panel 10. In one embodiment, the reinforcement panel 60 is positioned in the center of the central panel 10 so that the three openings 62 are aligned with the three middle openings 12 in the middle row of the openings in the central panel. In the illustrated embodiment, the two end notches 64 of the reinforcement panel 60 respectively cooperate with the middle notches 37 of the reinforcement flaps 32 to create a circular opening aligned with the two end openings 12 in the middle row of the openings in the central panel 10. The reinforcement panel 60 and reinforcement flaps 32 cooperate to add stiffness to the carton 5 so that the central panel 10 does not rip or tear when the carton is carried by the handles 11, 13. The reinforcement panel 60 could be otherwise shaped, arranged, positioned, and/or configured, or the reinforcement panel could be omitted, without departing from the invention.
As shown in FIGS. 2 and 3 the assembled carton 5 is placed over the top of the containers C so that portions of the containers (e.g., upper portions, which include caps) protrude through the openings 12 in the central panel 10. The containers C and the carton 5 are secured together by an overwrap of flexible polymer film (e.g., shrink-wrap) or other packaging material M with the handles 11, 13 protruding outward from the packaging material at respective sides of the carton. The handle panels 26 of the handles 11, 13 may be folded inward so that the carton 5 may be grasped and carried at the handles. The fold lines 15, 17 of the central panel 10 allow the central panels to flex and conform to the shape of the containers C when the carton 5 is pressed against the top of the containers by the tight wrapping of the packaging material M. One or more strips of flexible packaging material M is typically wrapped completely around the longitudinal axis of the carton 5 and adhered to itself so that it forms an enclosure with open opposite ends. Alternatively, one or more strips of packaging material M can be wrapped completely around the lateral axis of the carton 5 and adhered to itself and can cooperate with the packaging material wrapped around the longitudinal axis to form the enclosure.
The carton 5 is particularly useful in providing space for printing of graphics such as advertising or other information to be displayed for the consumer. For example, the front panel 30, back panel 50, central panel 10 and first and second side panels 20, 40 may have graphics printed on the respective exterior surfaces of the panels to convey information to the consumer. In the embodiment of FIG. 1, the central panel 10 is a top panel that fits over the top of the containers C, but the central panel may be otherwise configured so as to fit over the bottom of the containers without departing from the invention. Typically, the packaging material M is transparent so that advertising displayed on any of the panels (e.g., front panel 30, back panel 50, central panel 10, and/or side panels 20,40) is visible after the packaging material is applied to the carton 5.
Also, the reinforcement insert 60 and/or reinforcement flaps 32 may be otherwise shaped and/or arranged or may be omitted without departing from the invention. The reinforcement insert 60 may be foldably attached to any of the various panels or flaps without departing from the invention. Also, the reinforcement insert 60 may be otherwise located on the interior surface or exterior surface of the central panel 10 without departing from the invention.

In the embodiment of FIGS. 12-13, the second side panel 440 is located at a second longitudinal end of the central panel 410 and is generally a mirror image of the first side panel 420. Accordingly, like reference numbers have been used to designate similar or identical components or features that comprise the first and second side panels 420, 440. The first and second side panels 420, 440 may be otherwise shaped and arranged without departing from the invention.
In the embodiment of FIGS. 12-13, the first handle 411 is formed in the first side panel 420 and the second handle 413 is formed in the second side panel 440 and has identical components as the first handle. The features that form the first and second handles 411, 413 of the carton include the elongate handle flaps 426 formed in the first panels 422 and the elongate handle openings 429 formed in the second panels 424. The handles 411, 413 may include other features or the illustrated features may be otherwise shaped and/or arranged without departing from the invention.
The blank 403 is formed into the carton by folding the handle reinforcement flaps 424 at lateral fold lines 423 so that respective handle reinforcement flaps are in face-to-face relation with the central portions 422 of the side panels 420, 440. The elongate handle openings 429 in the handle reinforcement flaps 424 are aligned with the elongate handle flaps 426 in the central portions 422. The handle reinforcement flaps 424 can be secured to the central portions 422 by adhesive (e.g., glue). The side panels 420, 440 are upwardly folded relative to the central panel 410 at respective fold lines 421, 441 to form a space for receiving the containers. Containers C are placed on the central panel 410 either before or after the folding of the side panels 420, 440 so that the containers are supported on the central panel 410. The lateral extensions 430 of the side panels 420, 440 can be folded relative to a respective central portion 422 of the side panels to be respectively shaped to curve around a corner of the package and at least partially form the front of the package. The lateral extensions 450 of the side panels 420, 440 can be folded relative to a respective central portion 422 of the side panels to be respectively shaped to curve around a corner of the package and at least partially form the back of the package. The lateral extensions 430, 450 are useful reinforcing the corners of the carton 405 and for providing front and back surfaces for presenting advertising or other information. As with the previous embodiments, the containers C and the carton 405 are secured together by an overwrap of shrink-wrap or other packaging material M. In some embodiments, the lateral extensions 430, 450 may be formed to curve around the corners of the carton 405 as the packaging material M is applied to the carton. The handles 411, 413 can be activated by uncovering the handles from the packing material M, or alternatively, the packaging material can be punctured, pushed and/or folded inward through the handle openings when the handles are activated. Regardless of the positioning of the packaging material M, the handles are further activated by inwardly folding the handle panels 426 into handle openings 429 so that the carton may be grasped and carried by the handles 411, 413.
In alternative embodiments, the first panels 422 can be downwardly folded relative to the central panel 410 and the central panel can be placed on top of the containers C prior to the application of the packaging material M.
In alternative embodiments, the packaging material M can be omitted from any of the embodiments shown herein without departing from the invention. Further, the packaging material can partially or fully enclose the exterior surface of the carton and the containers C held therein to form the package. The various handle panels illustrate herein may have fold lines or other features to facilitate actuation of the handles and grasping of the carton.
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, 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 invention, 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 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 invention.
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.
