Description




TECHNICAL FIELD




The present invention relates to product cartons, and more particularly, to cartons that can be converted from a shippable form to a displayable form.




BACKGROUND ART




Finished products are typically packed into cartons and shipped to merchants for sale to the general public. The merchants thereafter unpack the finished products and stack them manually on display racks or store shelves in order for consumers to easily locate and pick out products. This process is time consuming and labor intensive. Certain carton designs have attempted to address this problem through the use of convertible designs that allow the merchant to display products in the cartons in which they were shipped.




Leftwich et al., U.S. Pat. No. 5,657,872, discloses a storage/display container. The container has two removable sides and a removable top cover that enable a merchant to convert the container from a shipping container to a display container. The sides and top cover are removed from the container by the merchant and the products within the container are exposed with the two remaining sides and lips along the front and rear edges of the container defining the boundaries of the container. The front lip of the container can further be removed by the merchant to allow consumers to slide products out of the container if further containers are stacked on top.




Rosenbaum, U.S. Pat. No. 6,158,579, also discloses a storage/display container. The container includes a foldable portion comprised of the top of the container and a portion of the front of the container. A merchant utilizes the foldable portion of the container to create a fold up header at the rear of the container that displays advertising for the products within. After the fold up header is created the front of the container consists of a skirt that defines the front edge of the container and contains the products within.




These container designs allow merchants to display products within the cartons that the products were shipped in and can be placed by the merchant on the floor, countertop or shelves for consumers to view. However, placement of the cartons on a shelving unit creates problems in both designs and neither design allows a merchant to effectively choose between a floor/counter display and a shelf display. Specifically, in the case of the Leftwich et al. patent the container is placed on a shelf with the open side facing out. As a result, when the consumer views the container there is little or no surface space on the side of the container nearest the consumer to identify the products within. This problem may be magnified in regard to flat products or in situations where the products are pushed into the back of the container where the consumer cannot easily view the products within to identify them.




The Rosenbaum container can also be somewhat problematic for consumers and merchants. The container cannot easily fit in the opening between closely spaced shelves because of the fold up header created when the merchant converts the container into the display form. Furthermore, where the shelf spacing is such that the carton will fit in such opening, the fold up header is disposed in back of the shelf where consumers are unable to see printed material on the header due to obstruction and/or a lack of light. Thus, the consumer encounters the same problem as with the Leftwich et al. container, whereby the consumer is left with little viewable container surface by which to identify the products within. Also, the skirt prevents consumers from easily reaching into the bottom of the container to retrieve flat products and interferes with the ability of the merchant to readily ascertain the number of products remaining in the carton.




SUMMARY OF THE INVENTION




In accordance with one aspect of the present invention, a carton blank includes first and second spaced main panels and first and second side flaps abutting first and second side edges, respectively, of the first main panel. The carton blank further includes third and fourth side flaps abutting first and second side edges, respectively, of the second main panel and an intermediate panel disposed between first ends of the first and second spaced main panels. Also provided is a cover flap abutting a second end of the second main panel and a display flap having first and second portions adjacent to one another wherein the first portion is joined to a second end of the first main panel by a score line and the second portion is joined to the second end of the first main panel by a perforated line collinear with the score line.




A further aspect of the present invention comprehends a carton including top and bottom spaced main panels and first and second side flaps abutting first and second side edges, respectively, of the bottom main panel. The carton further includes third and fourth side flaps abutting first and second side edges, respectively, of the top main panel and secured to the first and second side flaps, respectively and an intermediate panel integral with first ends of the top and bottom spaced main panels. A display flap is also provided having first and second portions adjacent to one another wherein the first portion is joined to a second end of the bottom main panel by a score line and the second portion is joined to the second end of the bottom main panel by a perforated line collinear with the score line. A cover flap is joined to a second end of the top main panel and is secured to the display flap.




Other aspects and advantages of the present invention will become apparent upon consideration of the following detailed description.

Industrial Applicability




The process of erecting the carton blank


20


to obtain an erected carton


110


is illustrated in

FIGS. 3-6

. Referring first to

FIG. 3

, the carton blank


10


is oriented by a user with the side


95


having the score line


100


separating the first and second folding panel sections


96


,


98


facing up. All of the following steps of erecting the carton


110


are preferably undertaken by equipment designed to accomplish such steps but can also be accomplished manually.




The first and second side flaps


28


,


30


are folded up along the score lines


24


,


26


, respectively, as shown in

FIGS. 3 and 4

. Before, during or after this folding step the tabs


60


,


62


,


68


,


70


are folded up/in relative to the first and second side flaps


28


,


30


along the score lines


64


,


72


,


74


and along the scored and perforated line


66


. Adhesive of any suitable type is applied to outwardly-directed faces


60




a


,


62




a


,


68




a


,


70




a


(see also

FIG. 1

) of the tabs


60


,


62


,


68


,


70


, respectively, at any suitable point in the process. Thereafter, the display flap


36


and the intermediate panel


32


are folded upwardly along the lines


38


and


34


, respectively, and adhesively attached to the outwardly-directed faces


60




a


,


62




a


,


68




a


,


70




a


of the tabs


60


,


62


,


68


,


70


(FIG.


5


).




If desired, the foregoing steps can be undertaken in any suitable sequence. For example, one or both of the tabs


60


,


62


may be folded upwardly relative to the first side flap


28


and the first side flap


28


may thereafter be folded upwardly relative to the first main panel


22


. One or both of the tabs


68


,


70


can then be folded upwardly relative to the second side flap


30


and the second side flap


30


may thereafter be folded upwardly relative to the first main panel


22


. Adhesive can then be applied to the outwardly-directed faces


60




a


,


62




a


,


68




a


,


70




a


of the tabs


60


,


62


,


68


,


70


and the display flap


36


and the intermediate panel


32


may be folded upwardly in sequence or simultaneously into contact with the outwardly-directed faces


60




a


,


62




a


,


68




a


,


70




a


of the tabs


60


,


62


,


68


,


70


.




Referring again to

FIGS. 3 and 4

, the third and fourth side flaps


84


,


86


are then folded up along the scored and perforated lines


88


,


90


, respectively, relative to the second main panel


80


. Before, during or after such folding, adhesive is applied to inner faces


84




a


,


86




a


of the third and fourth side flaps


84


,


86


. After placing product in the carton, and as seen in

FIG. 5

, the second main panel


80


is then folded down along the scored and perforated line


82


until the second main panel


80


contacts one or more of upper edges


112


,


114


of the first and second side flaps


28


,


30


and an upper edge


116


of the display flap


36


. The third and fourth side flaps


84


,


86


are then folded down into contact with and adhered to outer surfaces


28




a


,


30




a


(also see

FIG. 1

) of the first and second side flaps


28


,


30


. If desired, adhesive may be applied to the outer surfaces


28




a


,


30




a


in addition to or in place of the adhesive on the inner faces


84




a


,


86




a


of the third and fourth side flaps


84


,


86


. Alternatively or in addition, the third and fourth side flaps


84


,


86


may be held in place by adhesive tape or any other securing means (not shown). Finally, the cover flap


92


is folded down along the score line


94


and the cover flap


92


is attached to the display flap


36


, preferably by adhesive tape (not shown), so that the carton


110


assumes the erected shipping form shown in FIG.


6


.




The process of converting the erected carton


110


into a first display form is shown in

FIGS. 7-11

. Referring to

FIG. 7

, the adhesive tape seal is first broken or severed by a user and the cover flap


92


is folded up along the score line


94


. Referring to

FIG. 8

, the second main panel


80


is then pulled up and torn from the third and fourth side flaps


84


,


86


along the scored and perforated lines


88


and


90


, respectively. The third and fourth side flaps


84


,


86


remain secured to the first and second side flaps


28


,


30


after such tearing.




Then, referring to

FIG. 9

, the third section


50


is punched or knocked out (if it has not already been removed from the first and second sections


40


,


44


). The user inserts a finger into the hole left by removal of the third section


50


and grasps and removes the second section


44


of the display flap


36


from the first section


40


and the first main panel


22


by tearing at the perforated lines


42


and


48


. At this time, the second tab


62


is also separated and removed from the first side flap


28


by tearing the scored and perforated line


66


.




At this point, the user has the option of converting the carton


110


into one of two display forms. If the carton is to be placed in closely-spaced shelves, the user may elect to remove the second main panel


80


and the attached cover flap


92


from the intermediate panel


32


(and the remainder of the carton


110


) by tearing along the scored and perforated line


82


, as seen in

FIG. 10

to obtain the configuration shown in FIG.


11


. This configuration comprises a first or limited height display form. Once the carton


110


is placed on the merchant's shelf with the display flap


36


facing outwardly, purchasers can readily observe printed material provided on the first section


40


identifying and/or promoting the product in the carton


110


.




In the event that the carton


110


is to be placed at a location where vertical spacing is not a limiting factor, the user may elect to convert the carton from the configuration shown in

FIG. 9

to a second display form. Specifically, as seen in

FIG. 12

, the user folds the second main panel


80


along the score line


100


to place the second folding panel section


98


into face-to-face abutment with the first folding panel section


96


. At this point the user tucks the cover flap


92


into abutment with the tabs


60


,


68


. The side edges of the cover flap


92


and adjacent portions of the second folding panel section


98


remaining after tearing of the scored and perforated lines


88


and


90


may slightly engage inner surfaces


120


,


122


of the side flaps


28


,


30


to maintain the second folding panel section


96


in position against the first folding panel section


98


. Alternatively or in addition, the cover flap


92


may be tucked behind the product in the carton


110


and/or adhesive and/or adhesive tape may be used to maintain the second folding panel section


96


in upstanding position against the first folding panel section


98


as seen in FIG.


13


. Preferably, an outer surface


124


of the second folding panel section


96


includes printed matter thereon identifying and/or promoting the product in the carton


110


.




In either form, a purchaser or the merchant can easily observe how much product remains in the carton


110


, due to the removal of the second section


44


of the display flap


36


from the first section


40


down to the level of the first main panel


22


. This feature is particularly useful in the case of flat or small product. Further, the merchant need not unpack product from the carton


110


prior to display thereof. Promotional matter on the carton


110


is readily observed by the customer.




As an alternative to the embodiments described above, the cover flap


92


may be secured by any suitable fastening means to the display flap


36


and may further be configured substantially identically to the display flap


36


. In other words, the cover flap


92


may include three sections shaped substantially identically to the sections


40


,


44


and


50


and which are separated from one another by lines of substantially similar design and shape as the lines


42


,


52


,


54


and


56


when the cover flap


92


overlies the display flap


36


. In such an embodiment, the section of the cover flap


92


overlying the section


44


may be secured to the second main panel


80


at a scored and perforated line. During conversion, the sections


50


and


44


, and the sections of the cover flap


92


corresponding thereto may be removed, leaving the section


40


and the section of the cover flap


92


corresponding thereto in place. In this case, the remaining portion of the cover flap


92


may have printed matter thereon describing or referring to the product in the carton.




In still another embodiment, all or portions of one or more of the first through fourth side flaps


28


,


30


,


84


,


86


, the intermediate panel


32


and/or the tabs


60


,


68


and


70


may be removed during the conversion process. This may be accomplished by tearing at one or more additional perforated lines or other line(s) of weakness. This may allow a the user to remove an entire corner of the carton to enhance the visibility of the product in the carton.




Numerous modifications to the present invention will be apparent to those skilled in the art in view of the foregoing description. Accordingly, this description is to be construed as illustrative only and is presented for the purpose of enabling those skilled in the art to make and use the invention and to teach the best mode of carrying out same.
