Description




FIELD OF THE INVENTION




The invention relates to a packaging blank. In particular, the invention relates to a packaging blank capable of forming a container having multiple internal compartments. The invention further relates to a container formed from the blank that includes multiple internal compartments and one or more display windows that provide a view of the internal compartments. Still further, the invention relates to a method of packaging articles in the container wherein the container is formed around the articles. The articles to be positioned can include a variety of components, including informational inserts, coupons, warranty cards, warning cards, pouches, sachets, or similar substantially flat articles.




BACKGROUND OF THE INVENTION




Conventional packaging includes top walls, bottom walls, side walls, and closure panels for containing various products. As known to those skilled in the art, packaging is typically formed from packaging blanks, or blanks for short. It will be understood that as used herein the term “blank” may include cardboard, rigid paper, flexible plastic, or similar products made of paperboard or plastic. In particular, the packaging industry favors the use of one-piece flexible blanks, which are readily incorporated into automated processes for forming packaging containers.




As used herein, the term “article” will refer primarily to an informational insert or insert for short. Typical inserts are large sheets of printed paper that are folded to a smaller size for inclusion into a packaging container. Generally, the inserts are inserted into the interior of the containers alongside the primary product.




Today, the packaging of inserts, in concert with an associated product, is managed in the product manufacturers' facilities. Actual insertion into the container is accomplished by either manual or automated processes. As an example, pharmaceutical manufacturers are often required to include one or more informational inserts along with their primary products (e.g., typically blister cards or plastic bottles of tablets). Manual insertion of inserts is slow and labor intensive. Although typically more efficient than manual insertion, automated insertion systems may result in increased waste, slower production speeds, and may also require additional labor on the line. By supplying an insert-embedded folding container, the need for manual or in-line insertion of inserts at the product manufacturer's site is eliminated, thus creating significant efficiencies in their production processes.




Product manufacturers in selected industries, such as the pharmaceutical industry, are required to incorporate Good Manufacturing Practices to ensure that the correct informational insert is married with the appropriate product being housed in the container. However, most containers lack windows that permit a view of the inserts and any identifying code (e.g., bar code) printed on the insert. Thus, once sealed, it is necessary to actually destroy the package in order to verify the process. Therefore, it is desirable to provide a packaging blank capable of forming a container that includes one or more display windows that permit viewing of one or more informational inserts contained therein. It will be understood that as used herein, the term “viewing” may include reading with the human eye or scanning with a bar code scanner.




Most current processes employed create packaging on one apparatus and then insert products and associated inserts on a separate apparatus after the container is formed. The method of packaging pharmaceuticals and inserts as described above typically uses a belt-driven conveyor for advancing a blank along a production line. In production, the blank is folded along fold lines and portions of the blank are secured to one another (e.g., by adhesive) to form a container. This process is typically completed by a packaging supplier who then ships the finished package to the product manufacturer. Subsequently, the product manufacturer mechanically inserts the primary product into the packaging. The insert can then either be manually or mechanically placed into the container.




Unfortunately, this method creates “dual inventories” at the product manufacturers' facilities. The product manufacturer is required to independently stock and track the primary product, the package, and the inserts up until the point of manufacture. Thus there is a need for a method for providing an insert-embedded folding container that simplifies the product manufacturer's inventory requirements.




OBJECT AND SUMMARY OF THE INVENTION




It is therefore an object of the present invention to provide for the packaging of a product and an associated insert suitable for use in automated processing.




Another object of the invention is the provision of a container formed from a blank that provides visual verification that the primary product is properly matched with its associated insert.




A further object of the invention is to increase the manufacturing efficiencies associated with placing informational inserts or other articles.




Yet another object of the invention is to improve inventory management by eliminating the necessity for manufacturers to track separate inventories for containers and inserts.




The invention meets these objectives with a packaging blank capable of forming a container having multiple internal compartments. In particular, the invention is a packaging blank having multiple display windows that provide a view of the internal compartments of the container upon construction. In another aspect, the invention is a method for packaging an article (e.g., insert) that incorporates the blank wherein the container is formed around the insert.




The foregoing and other objects and advantages of the invention and the manner in which the same are accomplished will become clearer based on the following detailed description taken in conjunction with the accompanying drawings in which:

DETAILED DESCRIPTION OF THE INVENTION




The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which a preferred embodiment of the invention is shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like numbers refer to like elements throughout.




An overall view of a container


16


formed from a preferred embodiment of a packaging blank


10


which incorporates features of the present invention is set forth in FIG.


1


. As used herein, the term “panel” is used in conjunction with the packaging blank of the present invention and refers to sections of the blank. Further, the term “wall” is used in conjunction with the container of the present invention and refers to structures forming the container.




As depicted in

FIG. 2

, the packaging blank


10


includes a top panel


11


, a bottom panel


12


, and an internal panel


13


. It will be understood by those of skill in the art that the terms top panel and bottom panel, and top wall and bottom wall, are also referred to as front panel and rear-panel in the packaging industry.




With reference to the orientation of the blank in

FIG. 2

, it will be understood that the term “width” refers to a distance measured from the lowermost portion of a side panel


14


,


15


or glue flap


21


,


22


to the uppermost portion of a side panel or glue flap. It will be further appreciated by those of ordinary skill in the art that, as used herein, the concept of a panel or wall being “between” two other panels or walls does not necessarily imply that the three panels or walls are contiguous (i.e., in intimate contact). Rather, as used herein, the concept of one panel or wall being between two other panels or walls is meant to describe the relative positions of the panels or walls within the blank or container structure, respectively. Similarly, as used herein, the concept of a first panel being connected to a second panel by a third panel, “opposite” the second panel, merely describes the relative positions of the first and second panels within the blank structure.




The bottom panel


12


of the preferred blank


10


as shown in

FIG. 2

includes opposing first and second side panels


14


,


15


, and at least two display windows


20


. An alternative embodiment of the preferred blank


10


may include a single window (not shown). The bottom panel


12


is connected to the top panel


11


by the second side panel


15


. Upon constructing the blank


10


into a container


16


, the window


20


facilitates bar code verification as discussed herein.




The internal panel


13


of the preferred embodiment is connected to the top panel


11


by a first glue flap


21


. As depicted, the top panel


11


is positioned between the bottom panel


12


and the internal panel


13


. The internal panel


13


includes a second glue flap


22


positioned opposite the first glue flap


21


. The width of the second glue flap


22


is preferably less than the width of the first glue flap


21


.




Advantageously, the blank


10


is capable of being folded such that the internal panel


13


divides the interior space defined by the top panel


11


and the bottom panel


12


in order to form more than one internal packaging compartment


23


. See FIG.


3


. Thus, the blank


10


is capable of forming a container


16


that has at least two internal compartments


23


for separately receiving a product


71


and an article


34


(e.g., insert).




In the preferred embodiment, the top panel


11


, bottom panel


12


, and internal panel


13


are substantially rectangular. Nevertheless, it will be understood that the top and bottom panels


11


,


12


and internal panel


13


are not limited to a rectangular shape and may be oval, polygonal, or elliptical in shape.




As illustrated in the preferred embodiment of

FIG. 2

, the packaging blank


10


may be a one-piece flexible blank formed from paperboard or plastic. The blank


10


includes an external planar side


24


and an internal planar side


25


. The external planar side


24


is preferably finished. As used herein, it will be understood that the term “finished” means coated with a material to produce an attractive glossy finish. The term “finished” will also be understood to mean the inclusion of printed material or other identifying indicia (e.g., a company's logo).




In order to facilitate the formation of a substantially rectangular container


16


, the widths of the first and second side panels


14


,


15


of the preferred embodiment are about equal to one another.




As depicted in

FIG. 2

, two pairs of dust flaps


30


are provided at opposing ends of the first side panel


14


and the second side panel


15


. Each pair of dust flaps


30


extend beyond the ends of the first and second side panels


14


,


15


, and are foldable along fold lines formed in the blank


10


. The dust flaps


30


form part of end closures for securing the container


16


as described herein. In the preferred embodiment, a pair of closure panels


31


is also provided at opposing ends of the bottom panel


12


. Alternatively, the pair of closure panels


31


may be attached to opposing ends of the top panel


11


. In yet another embodiment, a pair of closure panels


31


may be formed at opposing ends of both the bottom and top panel


12


,


11


so that the opposing closure panels may be folded inwardly against one another in an overlapping fashion and adhered to one another. As known to those skilled in the art, this latter embodiment forms what is known as a “sealed end” carton or container.




The outermost opposing ends of each closure panel


31


may include an outermost tuck flap


32


for insertion into the interior of the container


16


upon construction. Accordingly, the dust flaps


30


, closure panels


31


, and tuck flaps


32


form the end closures for securing the container


16


formed from the blank


10


.




As shown in

FIG. 2

, the preferred embodiment of the present invention provides a pull-flap


33


that is formed by perforations


26


in the bottom panel


12


. The pull-flap


33


is positioned on the bottom panel


12


adjacent to one of the display windows


20


and defines at least one side of a first window. As configured, the pull-flap


33


of the preferred embodiment defines the entire perimeter of a second window.




In this configuration, the pull-flap


33


formed in the blank


10


provides a consumer with easy access to an insert


34


that may be placed in one of the internal compartments


23


. Specifically, the pull-flap


33


permits the consumer to grasp the edge of the pull-flap adjacent a window, lift the flap away from the container


16


to tear the perforations


26


in the bottom panel


12


, thereby separating the pull-flap from the bottom panel and providing access to the insert


34


contained within an adjacent internal compartment


23


. See

FIGS. 4

,


5


, and


6


. Accordingly, the product


71


is preferably positioned in a first internal compartment


70


and the insert


34


is positioned in a second internal compartment


72


. See FIG.


3


.




As configured, the display windows


20


are positioned on the bottom panel


12


such that the external planar side


24


of the internal panel


13


is viewable through the display windows upon construction of the container


16


. The display windows


20


thereby provide a view of at least two different positions on the external planar side


24


of the internal panel


13


. Accordingly, two windows would provide a view of two separate inserts


34


and any indicia (e.g., bar code) printed thereon.




A perspective view of a second embodiment of the present invention is depicted in FIG.


7


. As illustrated in

FIG. 8

, the second embodiment of the invention includes a packaging blank


35


having a top panel


36


, bottom panel


37


, and an internal panel


38


. The bottom panel


37


is connected to the top panel


36


by a first side panel


39


, and includes at least one display window


40


. The internal panel


38


of the second embodiment is connected to the top panel


36


by a second side panel


41


. As depicted, the top panel


36


is positioned between the bottom panel


37


and the internal panel


38


.




The internal panel


38


includes a glue flap


42


positioned opposite the second side panel


41


. The glue flap


42


has a width that is less than the width of the first side panel


39


. As shown in

FIG. 9

, the second embodiment of the packaging blank


35


is likewise foldable such that the internal panel


38


(illustrated as an internal wall


67


) divides the interior space of a container


43


defined by the top and bottom panels


36


,


37


(illustrated as a top wall


65


and a bottom wall


66


), thereby forming a multi-compartmented container.




With reference to

FIG. 8

, the second embodiment likewise consists essentially of a one-piece flexible paperboard blank


35


that includes a finished external planar side


44


and an internal planar side


45


. In order for the second embodiment to facilitate the formation of the substantially rectangular container


43


, the width of the first side panel


39


and the width of the second side panel


41


are about equal.




The end closures of the second embodiment depicted in

FIG. 8

also include dust flaps


46


, closure panels


47


, and tuck flaps


48


similar to the first embodiment of FIG.


2


. In other words, the first and second side panels


39


,


41


each include a pair of dust flaps


46


formed at respective opposing ends. In addition, a pair of closure panels


47


and associated tuck flaps


48


is likewise provided at opposing ends of either the bottom panel


37


or top panel


36


to secure the container


43


. In another embodiment, a pair of closure panels


47


may be formed at opposing ends of both the bottom and top panel


37


,


36


so that the opposing panels may be folded against one another (i.e., overlapping) and adhered to form a sealed end carton.




The second embodiment also provides a pull-flap


49


formed by perforations


50


in the bottom panel


37


. As illustrated in

FIG. 8

, the edge of the pull flap


49


is positioned adjacent the display window


40


. As configured, at least one display window


40


is positioned on the bottom panel


37


such that the external planar side


44


of the internal panel


38


is viewable through the display window upon construction of the container


43


.




The multiple windows of the preferred embodiment and the single window of the second embodiment are similar with respect to their positioning. Stated differently, each window


20


,


40


of the first and second embodiments is positioned on the bottom panels


12


,


37


such that a portion of the external planar sides


24


,


44


of the internal panels


13


,


38


is viewable through each window when the packaging blanks


10


,


35


are formed into containers


16


,


43


.




Another aspect of the present invention, as illustrated in

FIG. 1

, includes a container


16


formed from the packaging blank


10


that has multiple internal compartments


23


. As described above, the term “wall” is used in conjunction with the container of the present invention—as opposed to the previously described blank. Further, the term wall refers to structures forming the container as opposed to the sections of the blank. With reference to the orientation of the container in

FIG. 1

, it will be understood that the term “width” refers to a distance measured from the base of the container to the top of the container.




A preferred embodiment of the container includes a top wall


55


, a bottom wall


56


, and an internal wall


57


. In the preferred embodiment the top wall


55


, bottom wall


56


, and internal wall


57


are substantially rectangular in shape, but may be oval, polygonal, or any similar shape supporting the construction of a container. The bottom wall


56


is connected to the top wall


55


by a first and second side wall


58


,


59


. At least one display window


20


is provided in the bottom wall


56


for viewing the internal wall


57


that is positioned between the top and bottom walls. See FIG.


3


. Alternatively, it will be understood that a preferred embodiment of the container


16


may include a single window. The internal wall


57


is connected at each end to the first and second side walls


58


,


59


. The positioning of the internal wall


57


thereby defines multiple internal packaging compartments


23


, that is to say, a first internal compartment


70


and a second internal compartment


72


, within the container


16


, as illustrated in FIG.


3


.




The internal wall


57


of the preferred embodiment of the, container


16


includes a first glue flap


61


that connects the internal wall to the first side wall


58


. The internal wall


57


also includes a second glue flap


62


attached to the second side wall


59


. The width of the second glue flap


62


is preferably less than the width of the second side wall


59


. The container


16


is preferably formed from a one-piece flexible paperboard blank


10


that includes an external planar side


18


and an internal planar side


25


. The container


16


may also be formed from a one-piece flexible plastic blank. A preferred embodiment of the container


16


includes a finished external planar side that may include printed matter or similar indicia. In this configuration, the top wall


55


, bottom wall


56


, and internal wall


57


form substantially parallel planes. See FIG.


3


.




The width of the first and second side walls


58


,


59


are about equal to facilitate the formation of a substantially rectangular container


16


. The first and second side walls


58


,


59


each include a pair of dust flaps


30


formed at opposing ends of the respective side walls. In the preferred embodiment, the bottom wall


56


includes a pair of closure panels


31


formed at opposing ends of the bottom wall. It will be understood that the pair of closure panels


31


may, alternatively, be positioned at opposing ends of the top wall


55


.




Each of the closure panels


31


may include a tuck flap


32


formed at opposing ends of the closure panels for insertion into the interior of the container


16


. In an alternative embodiment lacking tuck flaps


32


, an end closure may be formed from a pair of closure panels formed at opposing ends of both the bottom and top panel. In this configuration, the opposing panels may be folded inwardly against one another (i.e., overlapping) and adhered to one another, thus forming sealed end carton. It will be understood that an end of the container


16


may be secured in any number of ways consistent with standard packaging practices.




The preferred embodiment of the container


16


may also include a pull-flap


33


for providing access to the interior of the container. Specifically, perforations


26


in the bottom wall


56


define the pull-flap


33


that is positioned adjacent the display windows


20


. As discussed, the pull-flap


33


provides easy access to multiple inserts


34


positioned on the internal wall


57


without destroying the sealed and secured package. As configured, at least one display window


20


is positioned on the bottom wall


56


such that a portion of internal wall


57


is viewable through display windows


20


.




As shown in

FIG. 3

, the preferred embodiment includes any number of informational inserts


34


positioned on the internal wall


57


. In this fashion, the inserts are viewable through the display windows


20


.




An alternative embodiment of the container


43


also includes a top wall


65


, a bottom wall


66


, and an internal wall


67


. See FIG.


9


. The bottom wall


66


is likewise connected to the top wall


65


by a first and second side wall


68


,


69


. The bottom wall


66


, however, includes a single display window


40


. The internal wall


67


is similarly connected to the first and second side walls


68


,


69


. The internal wall


67


is also positioned between the top and bottom walls


65


,


66


, thereby forming more than one internal packaging compartment


23


. The internal wall


67


also includes a single glue flap


42


. In the second embodiment of the container


51


, however, the glue flap


42


is attached to the first side wall


68


. In this configuration, the top wall


65


, bottom wall


66


, and internal wall


67


form substantially parallel planes.




The second embodiment of the container


43


likewise may be formed from a one-piece flexible paperboard or plastic blank


35


that has an external planar side


44


and an internal planar side


45


. Preferably, the external planar side is finished.




In regards to end closures, the first side wall


68


includes a pair of dust flaps


46


formed at opposing ends of the first side wall. The second side wall


69


likewise includes a pair of dust flaps


46


formed at opposing ends of the second side wall. The bottom wall


66


includes a pair of closure panels


47


formed at opposing ends of the bottom wall. Alternatively, the top wall


65


may include a pair of opposing closure panels


47


. It will be understood that a pair of closure panels


47


may also be provided at opposing ends of both the top and bottom walls


65


,


66


for forming a sealed end. Each closure panel


47


may also include a tuck flap


48


formed at the outermost opposing ends of the closure panels.




A pull-flap


49


is also provided in the second embodiment of the container


43


. The pull-flap is similarly formed by perforations


50


in the bottom wall


66


, and positioned adjacent to the display window


40


. As described, the display window


40


is positioned on the bottom wall


66


such that a portion of the internal wall


67


is viewable through the display window.




Another aspect of the invention includes the use of the packaging blanks


10


,


35


of the present invention in conjunction with a method-for packaging articles (e.g., informational inserts). This method is preferably accomplished at a packaging supplier's facility, thereby eliminating the requirement for a product manufacturer to package the product and its associated article (e.g., insert) in separate insertion steps. Stated differently, the product manufacturer is not required to independently stock and track the primary product, the associated inserts, and the package. As depicted, a flexible blank that includes an internal planar side and an external planar side is provided on a work station.




In a preferred method, a blank


10


is provided that includes a bottom panel


12


having first and second side panels


14


,


15


, and a top panel


11


connected to the bottom panel by the second side panel. The preferred method further provides a blank


10


having an internal panel


13


that is connected to the top panel


11


by a first glue flap


21


positioned opposite the top panel.




The internal panel


13


is then folded over the top panel


11


to form, upon construction, a first internal compartment


70


in which a product


71


to be packaged is positioned, for example, at a product manufacturer's facility during the final stages of packaging. See FIG.


3


. Alternatively, a packaging manufacturer may incorporate the step of placing a product associated with the article on an internal planar side


25


of the flexible blank


10


. It will be understood that the product may be placed on the top panel


11


, the second side panel


15


, or the internal panel


13


in this alternative method.




Upon folding the internal panel


13


over the top panel


11


, the external planar side


24


of the blank


10


is presented for receiving at least one article


34


as described herein. In a preferred method, the internal panel


13


is folded along a fold line connecting the first glue flap


21


to the top panel


11


such that the internal panel is substantially parallel and adjacent to the top panel. In a preferred method, the blank provided includes a second glue flap


22


that is connected to the internal panel


13


, and positioned opposite the first glue flap


21


. As provided, the external planar side


24


of the second glue flap


22


is then adhered to the internal planar side


25


of the second side panel


15


. In the preferred method, the internal panel


13


is folded over the top panel


11


such that the folded blank


10


is substantially flat.




After folding the internal panel


13


over the top panel


11


and adhering the second glue flap


22


to the second side panel


15


, at least one article


34


is positioned on the external planar side


24


of the internal panel. It will be understood, that upon construction of the container, a second internal compartment


72


is formed in which the article is positioned. A preferred method of positioning the article


34


includes adhering the article to the external planar side


24


of the internal panel with adhesive or static charge.




The step of positioning an article may incorporate a conventional device that includes an arm having a suction means which retrieves an article and then positions the same on a panel of the blank. For example, an article


34


may be retrieved and then selectively placed on the blank


10


such that a bar code


63


on the article is viewable through a display window


20


upon construction of the container


16


. Accordingly, a bar code scanner positioned along an automated production line may scan the bar code

, thereby expediting pharmaceutical compliance. In other words, the product manufacturer can ensure that the appropriate article-embedded container is married with the appropriate product


71


(e.g., pharmaceutical) to be packaged in the container


16


.




Subsequently, the bottom panel


12


is folded over the internal panel


13


. In a preferred method, the bottom panel


12


is folded over the top panel


11


and the internal planar side of the first side panel


14


is adhered to the external planar side of the first glue flap


21


, thereby forming a substantially flat container suitable for shipment and capable of being constructed into a substantially rectangular container


16


.




Accordingly, the bottom panel


12


is folded over the internal panel


13


such that one or more articles


34


positioned on the internal panel are viewable though multiple display windows


20


formed in the bottom panel. The substantially flat container having an article


34


embedded therein, may subsequently be shipped to a product manufacturer where a product


71


can be married with its respective article-embedded container


16


. Specifically, the substantially flat container can be constructed in a rectangular container


16


and the product


71


associated with the article


34


can be positioned in the first internal compartment


70


.




Subsequently, the container may be secured by folding a pair of dust flaps


30


formed at opposing ends of the first and second side panels


14


,


15


against the internal panel


13


. A pair of tuck flaps


32


formed at the outermost opposing end of the bottom panel


12


is then inserted into the first internal compartment


70


. Consequently, a pair of closure panels


31


formed at opposing ends of either the top panel


11


or the bottom panel


12


are positioned adjacent each pair of dust flaps


30


and the container


16


is secured. Nevertheless, it will be understood that an end closure may be formed from closure panels


31


formed at opposing ends of the top and bottom panels


11


,


12


that do not include tuck flaps


32


, such that an end of the container


16


may be secured by overlapping and adhering the closure panels to form a sealed end, thus securing the container.




Accordingly, the present method whereby an article is positioned on the blank, and the container is subsequently formed around the article, promotes substantially higher assembly speeds and lower waste than existing methods, whereby the container is formed and then the article is inserted into the finished container. Stated differently, the present method positions an article during the formation of the container, as opposed to inserting the article after construction of the container. Accordingly, upon construction of the container, the finished package includes an article and is ready to accept an associated product. Moreover, the present method is capable of incorporating a wide variety of products into the present container. For example, cosmetics, gifts, small toys, and the like may be packaged along with an associated insert in accordance with the present invention. In addition, multiple products can be placed in the same package. In cases where the container forming equipment allows faster construction speeds than the capability of one retrieval arm device, additional retrieval units can be placed along the production line and synchronized to deliver the finished product at a faster rate than previously achieved.




In the drawings and specification, there have been disclosed typical embodiments on the invention and, although specific terms have been employed, they have been used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention being set forth in the following claims.
