Abstract
A folding carton is described that includes a hang tab that is slidable between a first position in which the hang tab is tucked behind a first carton panel, and a second position in which the hang tab extends out of the carton for hanging the carton on a display. The carton further includes a hang tab restraint for preventing the hang tab from being pulled entirely out of the carton. The hang tab is initially held in its first position by breakaway nicks that attach the hang tab to the carton. According to further aspects of the invention, the hang tab restraint comprises a yoke flap folded over the hang tab or, alternatively, a tongue member that fits into a central slot of the hang tab.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates generally to improvements in folding cartons, and particularly to advantageous aspects of a folding carton having a built-in, sliding hang tab.




2. Description of the Prior Art




Certain retail goods, such as cosmetics, are packaged in small cartons that are typically fabricated from a sheet of cardboard or plastic that has been cut into a predetermined shape, folded, and then glued. There are two basic modes for displaying these goods in a retail store. In a first “counter display” mode, the cartons are stacked on a flat surface, such as a counter or a shelf. In a second “hang display” mode, the cartons are hung on posts extending horizontally outward from a pegboard or other vertical surface. In a hang display, the upper portion of each carton is typically provided with a tab or flap having a hole or slot that slides over the post.




The choice of display mode is governed by two major considerations: the attractiveness of the display, and the efficient use of retail space. A counter display is typically more attractive than a hang display and is therefore chosen for higher-end products. Further, a hang tab or flap on a carton can be unsightly and interfere with the esthetic design of the carton. However, a counter display typically does not use retail space as efficiently as a hang display, in which several different items can be spaced closely together in both a vertical and a horizontal direction.




It may be desired for a number of reasons to use a counter display for a particular product in one retail setting, but to use a hang display for the same product in a different retail setting. It is desirable for reasons of economy and efficiently to use the same carton for both a counter display and a hang display. However, because of esthetic considerations, it is desirable for the hang tab to be hidden from view in a counter display and yet easily accessible for use in a hang display. Further, it desirable for such a hang tab to be manufactured as economically as possible.




SUMMARY OF THE INVENTION




In one aspect, the invention provides a folding carton having a hang tab that is slidable between a first, retracted position in which the hang tab is tucked behind a first carton panel, and a second, extended position in which the hang tab extends out of the carton for hanging the carton on a display. The carton further includes a hang tab restraint for preventing the hang tab from being pulled entirely out of the carton. The hang tab is initially held in its first position by breakaway nicks that attach the hang tab to the carton. According to further aspects of the invention, the hang tab restraint comprises a yoke flap folded over the hang tab or, alternatively, a tongue member that fits into a central slot of the hang tab.




Additional features and advantages of the present invention will become apparent by reference to the following detailed description and accompanying drawings.

DETAILED DESCRIPTION





FIGS. 1A and 1B

show rear perspective views of a first embodiment of a folding carton


10


according to the present invention. The carton


10


includes a hang tab


12


that, in

FIG. 1A

, is tucked behind the rear panel


14


of the carton


10


. In

FIG. 1B

, the hang tab


12


has been pulled out into an extended position, exposing an eye


16


that is dimensioned to fit over a post in a hang display. The hang tab


12


freely slides between its tucked and extended positions.




As described below, in the first embodiment of the invention, illustrated in

FIGS. 1A-B

,


2


, and


3


A-E, and in the alternative embodiments of the invention illustrated in

FIGS. 4

,


5


, and


6


A-C and discussed below, the carton includes a yoke arrangement that acts as a restraint, preventing the hang tab from being pulled all the way out of the carton. In the alternative embodiments of the invention illustrated in

FIGS. 7A-C

,


8


,


9


A-D,


10


, and


11


, discussed further below, the hang tab is prevented from being pulled all the way out of the carton by a tongue member extending from an interior surface of the carton that engages a slot in the hang tab.




In the first embodiment of the invention, the carton


10


shown in

FIGS. 1A and 1B

is fabricated from a sheet of cardboard that is cut and scored to form a blank that is then folded and glued, as described below. Other suitable materials that can be used to fabricate the carton include paperboard, corrugated or fluted board, plastic, etc. Also, it is possible to incorporate the present invention into a carton fabricated from more than one sheet of material, such as the windowed carton shown in FIG.


5


and discussed below, in which a sheet of mylar or other clear plastic is glued over an opening in a carton panel.

FIG. 2

shows an interior plan view of a blank


20


according to the present invention. When the blank


20


is fabricated from cardboard, the blank typically includes a glossy, coated side forming the exterior surfaces of the finished carton and a matte, uncoated side forming the interior surfaces of the finished carton. The exterior surface of the blank typically includes a graphic design, as well as printed text identifying the product and its ingredients. Although it would be theoretically possible to use cardboard having two glossy, coated sides, this adds to the cost of the carton. In

FIG. 2

, the blank


20


is shown from its uncoated, interior side.




As shown in

FIG. 2

, the blank


20


includes the following components: a right side panel


22


, a front panel


24


, a left side panel


26


, a rear panel


28


, a glue flap panel


30


having two sections


30




a


and


30




b,


and a hang tab support panel


32


. A hang tab


34


is affixed to the right section of the glue flap panel


30




b


by a breakaway nick


38


. The hang tab


34


is also affixed to a support arm


36


extending upward from the hang tab support panel


32


by breakaway nicks


40


. The hang tab


34


includes a head section


42


having an eye


44


punched therein, the eye


44


being dimensioned to fit over a display rod. The size and shape of the eye


44


may be modified, as needed. The hang tab


34


further includes a pair of shoulders


46


and


48


. In addition, the hang tab


34


, hang tab support arm


36


, hang tab support panel


32


and glue flap panel


30




b


together define a square opening


50


, the function of which is described further below.




The blank


20


further includes a top panel


52


with an integrally formed tuck


54


and a pair of dust flaps


56


,


58


for closing the top of the finished carton and a bottom panel


60


with its own integrally formed tuck


62


and dust flaps


64


,


66


for closing the bottom of the finished carton. This particular configuration of tucks


54


and


62


relative to the carton panels


22


-


28


is known as a French tuck. However, alternative configurations may also be used in conjunction with the present invention. In addition, the bottom panel


60


and tuck


62


include a pair of slit locks


68


,


70


that fit over corresponding locking projections


72


,


74


on the bottom dust flaps


64


,


66


for holding the bottom panel


60


and tuck


62


in place after they have folded to close the bottom of the finished carton.




Extending from the top of the rear panel


28


is a yoke flap


76


and yoke flap glue tab


78


. Between the base of the yoke flap


76


and the rear panel


28


is a yoke opening


80


. The yoke opening


80


is dimensioned such that the head section


42


of the hang tab


34


passes freely through the yoke opening


80


. However, the sides of the yoke opening


80


engage the shoulders


46


and


48


of the hang tab


34


to prevent the hang tab


34


from being pulled all the way through the yoke opening


80


. As shown in

FIG. 2

, score lines


82


and


84


are provided at either side of the yoke opening


80


to facilitate the folding of the yoke flap


76


down over the rear carton panel


28


.




In the first embodiment of the invention, the score line


86


between the rear panel


28


and the glue flap panel


30


, and all of the score lines to the left of that score line, are pressed into the blank


20


without penetrating the surface of the cardboard. The score line


88


between the two sections


30




a


and


30




b


of the glue flap panel


30


is cut part way through the cardboard because of the length of the score line


88


and because the two sections


30




a


and


30




b


of the glue flap panel


30


must be folded 180 degrees so that the two section


30




a


and


30




b


abut each other. The score line


90


between the glue flap panel


30


and the hang tab support panel


32


is perforated. This perforation is desirable because the blank


20


is first folded along score line


88


, and then folded along score lines


86


and


90


simultaneously. The use of a perforated score


90


allows both the exterior fold along score line


86


and the interior fold along score line


88


to be made cleanly.





FIGS. 3A through 3E

are sequential perspective views illustrating the construction and functioning of a sliding tab using the blank


20


shown in FIG.


2


. As shown in

FIG. 3B

, a first fold is made along score line


90


. After this fold is made, the two sections


30




a


and


30




b


of the glue flap panel


30


abut each other, and the hang tab support panel


32


abuts the rear panel


28


. In addition, the hang tab


34


is now positioned directly underneath the yoke opening


80


.




As illustrated in

FIG. 3C

, the yoke flap is then folded down over the hang tab


34


along score lines


82


and


84


. Score lines are provided through yoke side sections


82


and


84


to facilitate this fold. After the fold is made, the yoke flap glue tab


78


lies directly over the opening


50


underneath the hang tab


34


. As illustrated in

FIG. 3D

, the yoke flap glue tab


78


is glued to the rear panel


28


through the opening


50


. The gluing of the yoke flap glue tab


78


to the rear panel


28


traps the hang tab


34


underneath the yoke flap glue tab


78


. The uppermost portion of the hang tab


34


peeks through the yoke opening.




In the finished carton, the hang tab


34


is held in its tucked position by a first set of breakaway nicks


38


that connect it to the glue flap panel


30


and a second set of breakaway nicks


40


that connect it to the hang tab support arm


36


. However, these nicks


38


and


40


are easily broken by pulling upward on the exposed uppermost portion of the hang tab


34


. As illustrated in

FIG. 3E

, the hang tab


34


is prevented from being pulled all of the way out of the carton by the yoke flap


76


that engages the hang tab shoulders


46


and


48


.




The carton is further assembled by folding the front panel


24


, rear panel


28


, and side panels


22


and


26


so that they form a rectangular tube and by gluing the glue flap panel


30


to the inside of the right side panel


22


. The bottom dust flaps and tuck are then folded to close the bottom of the carton. The carton is filled, and then the top dust flaps and tuck are folded to close the top of the carton. These operations are typically performed by machine, but can also of course be performed by hand.




It will be appreciated that once the carton has been constructed, filled and closed, the lateral motion of the hang tab


34


underneath the yoke flap


76


is limited on one side by the left side panel


26


and on the other side by the glue flap panel


30


that has been glued to the right side panel


22


, which are now perpendicular to the rear panel


28


. If desired, the carton blank


20


may initially only be partially folded and assembled for shipping purposes and then completed at a later point in time.




Thus, the carton


10


illustrated in

FIGS. 1A and 1B

is suitable for use in both a counter display mode, shown in

FIG. 1A

, and a hang display mode, shown in FIG.


1


B. In the counter display mode, the hang tab


18


is in a first, retracted position, in which the hang tab


18


is tucked behind a first carton panel


14


. In the hang display mode, the hang tab


18


protrudes out of the carton


10


in a second, extended position, in which the hang tab


18


extends out from behind the first carton panel


14


for hanging the carton on a display. Further, the carton


10


may be converted back and forth between its counter display and hang display modes as many times as needed. This provides a retailer with maximum flexibility, without requiring different cartons for each display mode.





FIG. 4

shows a plan view of the interior side of a carton blank


100


according to a second embodiment of the present invention. As shown in

FIG. 4

, the blank includes a hang tab


102


having a pair of shoulders


104


and


106


and a narrower head section


108


. The hang tab


102


is mounted to a hang tab support panel


110


by a set of breakaway nicks


112


. The hang tab support panel


110


extends from the right side of a glue flap panel


114


having two sections


114




a


and


114




b


that are folded along a score line


116


, such that they abut each other in the finished carton.




The glue flap panel


114


extends from the right side of a rear carton panel


118


. Extending upward from the rear carton panel


118


is a yoke flap


120


. Between the yoke flap


120


at the rear carton panel


118


is a yoke opening


122


that is dimensioned so that the hang tab head section


108


passes freely through the yoke opening


122


. However, the hang tab


102


is prevented from being fully pulled through the yoke opening


122


by the engagement of the hang tab shoulders


104


and


106


by the sides of the yoke opening


122


.




The hang tab


102


and the yoke flap


120


are positioned with respect to each other such that when the glue flap panel


114


is folded along its central score


116


, the hang tab


102


is aligned directly under the yoke flap


120


. When the yoke flap


120


is then folded over the hang tab


102


, an upper portion of the hang tab


102


protrudes through the yoke opening


122


, thereby providing user access to the hang tab


102


. Further the yoke flap


120


includes at either side a pair of rectangular glue sections


124


and


126


, which are glued to the rear panel


118


on either side of the hang tab


102


. This traps the hang tab


102


beneath the yoke flap


120


, preventing lateral movement of the hang tab


102


.




When the carton has been fully assembled, if the user wishes to use the carton in a hang display, the user grasps the upper portion of the hang tab


102


protruding through the yoke opening


122


and pulls upward. This breaks the nicks


112


holding the hang tab


102


to the hang tab support panel


110


, along the hang tab


102


to be pulled upward until the sides of the yoke opening


122


engage the hang tab shoulders


104


and


106


.





FIG. 5

shows a plan view of the interior side of a carton blank


130


according to a third embodiment of the present invention. In this embodiment of the invention, the hang tab


132


again is provided with a pair of shoulders


134


and


136


and a narrow head section


138


. However, in the

FIG. 5

embodiment of the invention, the hang tab


132


is attached by a pair of nicked sections


140


and


142


to the top of a yoke flap


144


, which in turn extends from the top of a rear carton panel


146


. A yoke opening


148


is provided between the yoke flap


144


and the rear carton panel


146


. The yoke opening


148


is dimensioned to allow the hang tab head section


138


to pass freely through the opening


148


. However, the hang tab


132


is prevented from being pulled all the way through the opening


148


by the engagement of the hang tab shoulders


134


,


136


by the sides of the yoke opening


148


. The top of the yoke flap


144


includes a semicircular glue tab


150


that is used to glue the yoke flap


144


to the rear carton panel


146


around the hang tab


132


.




The construction of the yoking arrangement of the

FIG. 5

carton blank


130


is illustrated in

FIGS. 6A through 6C

. As shown in

FIG. 6A

, the hang tab


132


is folded downward along its nicked sections


140


and


142


, which function as score lines, until the hang tab


132


abuts the yoke flap


144


. This folding exposes the yoke flap glue tab


150


. As shown in

FIG. 6B

, the folded hang tab


132


and yoke flap


144


are then folded down over the rear carton panel


146


, and the yoke flap glue tab


150


is glued to the rear carton panel


146


. For purposes of illustration, in

FIG. 6B

, the yoke flap


144


is transparent, showing the position of the hang tab


132


. Typically, yoke flap


144


will be opaque. The dimensions and position of the hang tab


132


and the yoke opening


148


are chosen such that after this operation is performed, an upper portion of the hang tab


132


protrudes through the yoke opening


148


for user access.




If a user wishes to use the finished carton in a hang display, the user grasps the upper portion of the hang tab


132


protruding through the yoke opening


148


and pulls upward. This causes the hang tab


132


to break away from the yoke flap


144


along the nicked sections


140


and


142


. As illustrated in

FIG. 6C

, the hang tab


132


can then be pulled upward until the hang tab shoulders


134


and


136


engage the sides of the yoke opening


148


. It will be seen that the gluing of the glue tab


150


to the rear carton panel


146


traps the hang tab


132


between the yoke flap


144


and the rear carton panel


146


.





FIG. 7A

shows a further embodiment of a folding carton


160


according to the present invention. The carton


160


includes a hang tab


162


that, in

FIG. 7A

, is tucked behind the rear panel


164


of the carton


160


.

FIG. 7D

shows the hang tab


162


pulled out to its fully extended position, exposing an eye


166


in the hang tab


162


that is dimensioned to fit over a post in a hang display.

FIG. 7C

is a front view of the hang tab


162


, removed from the carton


160


. In addition to the eye


166


, the hang tab


162


further includes a central slot


168


and a bottom crossbar


170


.




As shown in

FIGS. 7A and 7B

, the rear panel


164


of the carton


160


further includes a tongue member


172


that pushes into the interior of the carton


160


. The tongue member


172


is dimensioned to closely fit within the central slot


168


of the hang tab


162


. Thus, as illustrated in

FIG. 4B

, when the tongue member is inserted into the hang tab slot


168


, the upward movement of the hang tab


168


is restrained by the hang tab crossbar


170


engaging the base of the tongue member


166


.





FIG. 8

shows a blank


180


that can be used to construct the carton


160


shown in

FIGS. 7A and 7B

. The blank


180


is shown from its unfinished interior side, and includes the following elements: a right side panel


182


, a front panel


184


, and left side panel


186


, a rear panel


188


with an integrally formed tongue member


190


, and a glue flap panel


192


. The top of the blank


180


includes a top panel


194


with a tuck


196


and a pair of dust flaps


198


and


200


for closing the top of the finished carton. The bottom of the blank


180


includes a bottom panel


202


with a tuck


204


and a pair of slit locks


206


and


208


, and a pair of dust flaps


210


and


212


with projections


214


and


216


that interlock with the slit locks


206


and


208


to close the bottom of the finished carton.




Extending from the top of the rear panel is a hang tab


218


, which is upside-down in the blank


180


, as during fabrication of the carton, it will be folded down towards the rear panel


188


along a pair of breakaway nicked sections


220


and


222


that, until they are broken, function as score lines. The hang tab


218


includes an eye


214


dimensioned to fit over a post in a hang display. The hang tab


218


further includes a central square


226


that is cut through on three sides and is held in place by a series of nicks


228


at its bottom. The central square


226


is positioned such that when the hang tab


218


is folded down over the rear panel


188


along nicked sections


220


and


222


, the central square


226


is positioned directly over the tongue member


190


in the rear panel


188


. A cut


230


is provided between nicked sections


220


and


222


. The cut


230


is shaped such that when the hang tab


218


is folded down over the rear panel


188


, the uppermost portion of the hang tab


218


projects upward, allowing ready access to the hang tab by the user of the carton.





FIGS. 9A through 9D

show a series of sequential perspective views illustrating the construction and operation of the hang tab


218


shown in FIG.


5


. As shown in

FIGS. 6B

and


6


C, the hang tab is folded along score lines


220


and


222


until it abuts the rear panel


188


. In addition, the central square


226


lies directly over and abuts the tongue member


190


in the rear panel


188


.




The central square


226


is glued onto the tongue member


190


, such that when the tongue member


190


is pushed into the interior of the carton, the central square


226


breaks off and becomes part of the tongue member


190


. This construction serves to reinforce the tongue member


190


and also ensures a close fit of the tongue member


190


into the central slot remaining in the hang tab after the central square


226


has been broken away. As illustrated in

FIG. 6D

, after the tongue member


190


has been pushed into the interior of the carton and the central square


226


has been broken away, the hang tab


218


can then be pulled upward by breaking the nicked sections


220


and


222


at either side of the hang tab


218


. As described above, the tongue member


190


and the attached central square


226


prevent the hang tab from being pulled completely out of the carton by engaging the cross bar at the bottom of the hang tab's central slot.




When the box is fully constructed, the front panel


184


, right and left side panels


182


and

, rear panel


188


and glue flap panel


192


are folded into a rectangular tube, and the glue flap panel


192


is glued to the interior surface of the right side panel


182


. It will be seen that the lateral movement of the hang tab


218


after it has been broken away from the rear panel


188


is limited by the left side panel


186


and the right side panel

FIG. 10

shows a plan view of the interior side of a carton blank


240


according to a further embodiment of the present invention. Although the overall shape of the carton is somewhat flatter and wider, this carton blank


240


is similar in structure and function to the carton blank shown in

FIGS. 7A-C

,


8


, and


9


A-D. Of particular interest in the

FIG. 10

carton blank


240


is the cutout section


242


between the hang tab


244


and the rear carton panel


246


. The cutout


242


is crescent-shaped and serves to facilitate the folding of the hang tab


244


down over the rear carton panel


246


and to facilitate access to the hang tab


244


in the finished carton. In particular, the cutout


242


prevents the unattached portion of the hang tab


244


immediately adjacent to the rear carton panel


246


from getting caught by the rear carton panel


246


during the folding operation. It is this unattached portion of the hang tab


244


that protrudes upward in the finished carton to provide ready access by the user. Again, after the hang tab


244


is folded down over the rear carton panel


246


, a breakaway central square section


245


of the hang tab


244


is glued to a tongue member


247


formed in the rear carton panel


246


.





FIG. 11

shows a plan view of the interior side of a carton blank


250


according to a further embodiment of the present invention. Here, instead of being cut into the rear carton panel, the tongue member


252


is disposed inside of a supporting frame


254


that extends from a glue flap panel


256


, which in turn extends from the carton's right side panel


258


. The blank


250


further includes a front panel


260


, a left side panel


262


, and a rear panel


264


. A hang tab


266


having a breakaway central square portion


268


extends upward from the rear panel


264


. During construction of a carton from the blank


250


, the hang tab


266


is folded down over the rear carton panel


264


. After the tongue member


252


, supporting frame


254


and glue flap panel


256


have been folded into position, the hang tab's central breakaway square portion


268


is glued to the tongue member


252


, and the glue flap panel


256


is glued to a corresponding portion of the rear carton panel


264


. In the finished carton, when the hang tab


264


is pulled upward, it causes the central square member


268


to break away, remaining attached to the tongue member


252


which engages the central slot remaining in the hang tab


266


after the central square member


268


has been broken away.
