This invention relates to a carton and a blank for forming the carton for containing a number of articles, and in particular, to a carton, the capacity of which can be increased to accommodate additional items and provide access to the articles in the carton.
Cartons for encasing multiple articles are useful for enabling consumers to obtain and transport a desired quantity of individual articles such as soft drinks or other beverages.
It is often desirable to serve a large quantity of containers, such as beverage and foodstuff containers, in a chilled condition. It may be desirable or necessary to chill such containers at locations or events for which there is little or no access to refrigerators or freezers, or at events for which it is not desirable to use refrigerators or freezers. For example, a large quantity of beverage and foodstuff containers may be served at parties, cookouts, picnics or vacation spots where it is desired to chill the containers for an extended period of time. In such cases, it is customary to place the containers in a cooler containing ice, which often requires the containers to be removed from their original packaging. In some cases, it would be advantageous to be able to chill containers in their original packaging without having to provide a separate cooler. Such cartons need to be strong enough to support multiple articles. It is also desirable for such cartons to be easy to handle and portable. It is also useful for the consumer to be able to add ice-cubes into such a carton to cool the beverage cans or bottles contained within the carton. It is also often desirable for the cartons to be adaptable so that the capacity of the carton can be increased to accommodate the addition of ice-cubes.
Such cartons are known in the art, but each has certain drawbacks. Many such cartons do not provide a means for increasing the capacity of the carton to accommodate the addition of ice cubes and so the carton is limited in the number of ice cubes which it can receive and the degree to which the containers in the carton are adequately chilled.
A carton having additional side and end panels which can be unfolded to provide additional capacity to the carton is known, but many such cartons require a considerable quantity of material to form the carton.
The prior art devices suffer from several drawbacks. The prior art devices do not allow incorporation of refrigeration elements into a standard paperboard beverage carton. Moreover, the prior art devices fail to effectively maximize the contact areas between the beverage containers and chilling elements, which enhances the cooling function provided by such chilling elements. These and other drawbacks of the prior art are overcome by this invention.
In view of the above, it is desirable to provide a carton that is convertible from a first configuration for holding containers during storage and/or transport to a second configuration in which the carton forms a cooler configured to receive ice for chilling and serving the containers while minimizing the amount of material required to form the carton.
One aspect of this invention is a carton for holding a number of containers. In one example, the carton has a number of panels extending at least partially around an interior of the carton. The panels can include a bottom panel, a first side panel foldably connected to the bottom panel, a top panel foldably connected to the first side panel, a second side panel foldably connected to the bottom panel, and an expansion mechanism. Opposite ends of the side panels may be respectively foldably connected to gusset folds that are mounted to end flaps extending from the bottom panel. An access feature for providing access to the interior of the carton (e.g., a dispenser) may extend in at least the top panel.
The bottom panel, first and second side panels and a top panel may together extend at least partially around an interior of the carton. The gusset folds, optionally in conjunction with expansion panels, may provide expandable connections between the top panel and the side panels. The expandable connections may be spaced apart from one another, and the expandable connections may be expandable so that the side panels are moved outwardly relative to the top panel, from an inner configuration to an outer configuration, to at least partially define an upwardly open space for being open to the interior by way of the dispenser.
Each of the gusset folds may include one or more pleats. In one specific example, each expandable connection includes a gusset flap connected to one of the panels, an intermediate flap and a gusset flap connected to the bottom end flap.
The foregoing presents a simplified summary of some aspects of this invention to provide a basic understanding. The foregoing summary is not extensive and is not intended to identify key or critical elements of the invention or to delineate the scope of the invention. The purpose of the foregoing summary is to present some concepts of this disclosure in a simplified form as a prelude to the more detailed description that is presented later and other aspects will become apparent from the following.
The above-mentioned and other features and advantages of this invention, and the manner of attaining them, will become more apparent and the invention itself will be better understood by reference to the following description of embodiments of the invention taken in conjunction with the accompanying drawings, wherein:
Exemplary embodiments of this invention are described below and shown in the accompanying drawings, in which like numerals refer to like parts throughout the several views. The embodiments described provide examples and should not be interpreted as limiting the scope of the invention. Other embodiments, and modifications and improvements of the described embodiments, will occur to those skilled in the art and all such other embodiments, modifications and improvements are within the scope of this invention.
This invention generally relates to opening, dispensing, and cooling features for cartons that contain articles such as containers, bottles, cans, 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, glass; 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 this invention can accommodate articles of any shape. 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., aluminum beverage cans) as disposed within the carton embodiments.
The carton can be used to house a number of articles such as containers C (shown by way of example in
Referring to
The carton blanks 10 of
In various embodiments of the carton blank 10 according to this invention, the carton blank 10 is symmetric about both a longitudinal and a lateral line bisecting the carton blank 10 in those directions.
A gusset fold 38 joins a lateral side edge of each bottom panel flap 36 to the adjacent side panel 18 via fold lines 39, 41. Each gusset fold 38 according to various embodiments of this invention includes three gusset flaps 40, 42, 44 each separated by gusset fold lines 46, 48 as shown in
The cartons 12 erected from the respective carton blanks 10 of
Handles 61 are provided on each end of the carton 12. A handle aperture 62 is formed in each of the bottom panel end flaps 36 of the carton blanks 10 of
In the embodiment of the carton blank 10 shown in
A glue line 72 is provided on one of the top panels 22. When the carton blank 10 is folded about the various transverse fold lines 24, 26, 28, 30, the top panels 22 overlap each other and are adhered together by the glue line 72 to form a unitary top panel from the multiple top panels 22 of the blank 10.
The pairs of expansion panels 20a, 20b are likewise adhered together by one or more glue deposits 74 provided on the print side of one of the expansion panels 20 of each pair of expansion panels. The glue deposit 74 is a single line of glue on the carton blanks 10 of

Another aspect of erecting the respective cartons 12 from the associated carton blanks 10 is the expansion panels 20 positioned between the side panel 18 and associated top panel 22. As shown generally in
Once the carton blank 10 is erected into the carton 12 and filled with the containers C, the ends of the carton 12 are closed and sealed to thereby form a package including a carton 12 filled with containers C as shown generally in
Removal of the dispenser panel 54 from the carton 12 according to one embodiment is shown in
Removal of the dispenser panel 54 according to another embodiment is shown in
The dispenser panel 54 according to the third embodiment of this invention is removed from the carton 12 as shown in
Removal of the dispenser panel 54 frees the end portions 20c, 20d of the expansion panels 20 in each embodiment. As such, after the dispenser tear line 56 is torn, the outer ends 20c, 20d of the expansion panels 20 which are not adhered together expand into the configuration shown in
One aspect of the expandable beverage carton 12 according to various embodiments of this invention is that the entire bottom portion of the carton 12 in the expanded configuration remains intact thereby containing not only the beverage containers, but the ice 14 and any water which may melt within the carton 12 thereby avoiding or minimizing drainage from the carton 12. The non-print side of the carton blank 10 may be coated with an appropriate film or other fluid barrier to enhance the retention of water within the carton as desired.
Another aspect of various embodiments of this carton 12 in the expanded configuration is that the handles 61 positioned on the opposite ends of the carton 12 remain intact and structurally functional for further transport of the carton 12 in the expanded configuration and its contents as necessary even after the dispenser panel 54 has been removed.
In general, the blank 10 may be constructed from paperboard having a caliper so that it is heavier and more rigid than ordinary paper. The blank 10 can also be constructed of other materials, such as cardboard, or any other material having properties suitable for enabling the carton 12 to function at least generally as described above. The blank 10 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 blank 10 may then be coated with a varnish to protect information printed on the blank 10. The blank 10 may also be coated with, for example, a moisture barrier layer, on either or both sides of the blank. The blank 10 can also be laminated to or coated with one or more sheet-like materials at selected panels or panel sections.
While various features of this invention have been described as tear lines or fold lines, such features may have other characteristics. 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 this invention 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 this invention.
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 this invention, fold lines may 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.
From the above disclosure of the general principles of this invention and the preceding detailed description of at least one embodiment, those skilled in the art will readily comprehend the various modifications to which this invention is susceptible. Therefore, I desire to be limited only by the scope of the following claims and equivalents thereof.
