Abstract
A closure for use closing the fin panel of an associated gable top carton includes a pair of opposing side walls each defining a free end and being connected to one another at an opposing end by a bridge wall. The closure is pivotally mountable to the upstanding fin and extending along at least a portion of the fin panel. The closure is pivotal between a closed position wherein the side walls are urged over the fin panel to engage and compress separable portions of the fin panel together when the dispensing opening is closed, and an open position in which the side walls are pivoted away from the fin panel to disengage the separable portions of the fin panel to open the dispensing opening.
Description




FIELD OF THE INVENTION




This invention pertains to a closure for gable-top cartons. More particularly, the invention pertains to a hinged clip-type closure for resealing gable-top packages after initial opening.




BACKGROUND OF THE INVENTION




Gable-top and brick-type packages have become widely accepted by consumers, packagers and the like for packaging liquid foods, such as milk and juice. To a much lesser extent, these packages are in use for packaging particulate-containing liquid foods and solid foods. However, due to the nature of the arrangement of these packages, vis-a-vis the container opening or spout, their use has been limited with respect to solid foods.




The conventional gable-top package is the standard barer for packaging liquid foods. Closure technology associated with gable-top cartons has shifted toward the use of plastic or like spouts that are fixed to one of the gable panels of the carton. The spouts are typically resealable, such as by a threaded cap or a flip-type snap cap, to help prolong the life of the product after initial opening of the package. These closures impede oxidation of the packaged product in that they are liquid tight, and for the most part, gas impermeable. This has been seen as a quantum improvement over known gable-top package openings in which the sides of the gable are opened to form a spout from the underlying packaged material.




It has, however, been found that in many instances incorporating these spouts into packages is not a cost effective solution for packaging lesser expensive product. It has also been found that in some instances the spouts are not conducive for use with solid or particulate-containing product in that these spouts are not sufficiently large to allow dispensing the solid or particulate-containing product from the package. To this end, although gable-top packages are used for packaging these solid or particulate-containing products, resort is often made to the conventional panel opening gable carton,“Traditional” gable-top package drawbacks still exist, even when used with solid or particulate-containing product. For example, the product can be subject to oxidation (and in the case of packaged product that absorbs moisture, moisture ingress into the package and thus the product), and potentially spillage. While these drawbacks can discourage use of this type of package for these products, this package arrangement is nevertheless in use in that readily dispensing product from the package is of utmost importance.




Accordingly, there exists a need for a closure for a gable-top carton that provides a resealable, wide dispensing opening for the carton. Desirably, such a closure permits use of the dispensing opening that is formed by the gable panels of the package. Most desirably, such a closure provides spill proof, relatively liquid and gas impermeable resealing of the package after initial opening. Also most desirably, such a closure is a low cost component readily usable with standard gable-top cartons.




SUMMARY OF THE INVENTION




A closure for use with a gable top carton provides a resealable, wide dispensing opening for the carton by using the dispensing opening that is formed by the gable panels of the package. The closure provides spill proof, relatively liquid and gas impermeable resealing of the package after initial opening.




The closure is configured for use on a gable-top cartons having a plurality of side walls, a sealed bottom wall and a plurality of top walls including a pair of gable panels terminating at an upstanding fin panel. The fin panel has separable portions that are separable, in part, to form a dispensing opening. The separable portions are reopenable and resealable to open and close the dispensing opening.




The closure includes a pair of side walls each defining a free end and being connected to one another at an opposing end by a bridge wall. The closure is pivotally mountable to the upstanding fin and extends along at least a portion of the fin panel.




The closure is pivotal between a closed position wherein the side walls are urged over the fin panel to engage and compress the separable portions of the fin panel when the dispensing opening is closed, and an open position wherein the side walls are pivoted away from the fin panel to disengage the separable portions of the fin panel to open the dispensing opening.




In a current embodiment, the closure is permanently mounted to the carton fin panel. Alternately, the closure can be configured as an “after-market” item, in which it include a base portion and a pivotal portion pivotally mounted to the base portion. The base portion is configured for stationary receipt on the fin panel, spaced from the fin panel separable potions and the pivotal pivots from the base portion between the open and closed positions.




The closure defines a throat area for receiving the fin panel. A widened entry region can be formed adjacent the throat area. The side walls can be inwardly tapered from the bridge wall to the side wall free ends.




The closure defines a sealing region and a hinge region. A pivot is disposed at the hinge region for pivotally moving the closure between the open position and the closed position. The carton includes an opening formed in the fin panel, and the pivot is configured for receipt in the fin panel opening.




The pivot can be formed as a projection extending inwardly from an inner surface of one of the side walls. An opening can be formed in the other of the side walls in a projecting manner to the projection to facilitate forming (e.g., molding) a the projection integral with the side wall from which it extends. The projection can be formed having an angled end distal from the side wall from which the projection extends.




Alternately, the pivot can be formed as a portions of the side wall urged inwardly to define wing-like elements. Preferably, the wing-like elements have arcuate outermost portions to facilitate pivoting the closure between the open and closed positions.




Still alternately, the pivot can be formed as a stub extending outwardly from the side wall from which it is formed. In this configuration, the stub is connected to the side wall by at least one frangible portion. The frangible portions break wherein the stub is urged into the fin panel opening.




To assure that the stub remains in place in the closure, a receiving opening is formed in an opposing, projecting position on the opposite side wall. The receiving opening is configured for receiving the stub when the stub is urged from the side wall into the fin panel opening and the opposing side wall. Preferably, the receiving opening has angled walls for frictionally securing the stub therein.




In one configuration, the bridge wall extends along only the sealing region. This permits 180 degree rotation of the closure between the open and closed positions. The closure can be configured with one or more serrations formed in an inner surface of one or both side walls. The serrations extend inwardly of the side walls for frictionally engaging the fin panel when the closure is in the closed position.




Optionally, the closure includes one or more detents extending inwardly from an inner surface of the side walls near the pivot. The detents are engagable with the fin panel to maintain the closure in the open position.




Other features and advantages of the present invention will be apparent from the following detailed description, the accompanying drawings and the appended claims.

DETAILED DESCRIPTION OF THE REFERRED EMBODIMENTS




While the present invention is susceptible of embodiment in various forms, here is shown in the drawings and will hereinafter be described presently preferred embodiments with the understanding that the present disclosure is to be considered an exemplification of the invention and is not intended to limit the invention to the specific embodiments illustrated.




Referring to the figures and in particular to

FIG. 1

, there is shown a standard gable-top package or carton


10


that will be well recognized by those skilled in the art as well as most consumers. The gable-top package


10


includes upstanding side walls


12


, a sealed bottom wall (not shown) and the familiar gable top


14


. The gable top


14


is defined by exterior panels


16


that are sealed to one another at a fin


18


. The gable portion


14


also includes interior gable panels


20


that fold inwardly, under the exterior gable panels


16


.




The fin is formed from panels


18




a-f


. The panels


18




a,b


(in part) and


18




c,d


can be separated from one another, as seen in

FIG. 2

, to form the familiar dispensing opening or pour spout


22


. The spout


22


is merely urged open to dispense product from the carton


10


, and folded inwardly to close the carton


10


. As will be recognized by those skilled in the art as well as consumers, although this dispensing opening


22


provides a wide area for dispensing product from the carton


10


, closing this traditional carton spout


22


does not effect a good seal for the stored product. To this end, moisture and/or oxygen can enter the carton


10


or the carton


10


can be turned onto an end, possibly resulting in spillage.




A closure


24


is fitted to the gable portion


14


at the fin


18


. The closure


24


permits use of the wide opening


22


that is made by separating the gable panels (portions of


16


,


20


) and fin panels


18




a,b


and


18




c,d


at the top fin


18


, and provides a positive reseal of the container


10


by exerting pressure on the fin panels


18


when it is in place.




Referring to

FIGS. 1-3

, the closure


24


is configured as a pivotable clip. It includes a pair of elongated side walls


26


,


28


connected to one another at an upper end


30


,


32


by a bridge wall


34


. The clip


24


is configured so that free ends


36


,


38


of the side walls


26


,


28


, opposite the bridge wall


34


, define a throat area


40


. The side walls


26


,


28


can include outwardly turned portions


42


,


44


, at the free ends


36


,


38


to provide an entrance into the constricted throat area


40


. The walls


26


,


28


can be tapered (as seen in

FIG. 8

, one wall tapered at


27


) to provide for readily applying he clip


24


over the fin panels


18




a,b


and to further provide the restricted or reduced throat area


40


.




The clip


24


is configured to fit over the fins panels


18




a,b


and squeeze or compress them together. This provides an excellent seal, and prevent the ingress of moisture and oxygen and the egress (i.e., leakage or spillage) of liquid, even if the carton


10


is inadvertently turned onto its side.




Referring to FIG.


3


. the clip


24


includes a sealing region


46


, a hinge region


48


and a hinge pin or pivot


50


. The side walls


26


,


28


extend along a length of the fin panels


18




a,b


and exert pressure on (i.e., compress) the panels


18




a,b


when in place. The walls


26


,


28


have a height h


w


that is sufficient to permit positioning the clip


24


down over a sufficient height h


f


of the fin panels


18




a,b


to assure that it remains in place when positioned thereon.




The height h


w


of the walls


26


,


28


can be shortened at about the hinge region


48


. This can be formed by removing the bridge wall


34


at the hinge region


48


. Referring to

FIG. 2

, this permits “flipping” the clip


24


rearward, out of the way of the fin panels


18




a,b


to open the carton


10


. The height h


w


of the walls


26


,


28


can be such that the clip


24


can be “flipped” about 180 degrees from the closed position (

FIG. 1

) to the open position (FIG.


2


).




As will be described below, the pivot


50


can take many forms. In one embodiment, as seen in

FIGS. 5

,


8


and


11


, the pivot


50


is formed as a projection


52


that extends as a simple, cylindrical element that is integral with and extends inwardly from one of the side walls, such as wall


26


of the closure


24


. The projection


52


is formed having an angled end wall


54


to facilitate placement over the fin


18


. An opening


56


is formed in the opposing side wall


28


in projecting fashion to the projection


52


. Such an arrangement permits readily manufacturing the closure


24


. This is particularly so in that it is contemplated that the closure


24


will be formed in a molding process (such as an injection molding process) in which mold tools (not shown) will be required to form the pivot projection


52


. The side wall opening


56


permits ready access for a mold tool into the interior portion of the closure


24


to form the projection


52


.





FIGS. 6 and 6A

illustrate an alternate pivot


150


that can be used with the present closure


124


. In this alternate pivot


150


arrangement, a portion of the side wall


126


is partially punched or urged from the plane P


w


of the side wall


126


, into the interior portion of the clip


124


. The punched portions


152




a,b


(which as seen in

FIG. 6

have a wing-like appearance) can be made having cured or arcuate upper and lower surfaces


154




a,b


to facilitate the pivoting function. In this manner, a relatively simple and straight forward pivot is formed from the side wall


126


material of the clip


124


. Although now shown in

FIGS. 6 and 6A

, the wing-like, pivot elements


152




a,b


can be punched sufficiently deeply into the central portion of the clip


124


so as to extend essentially to the opposing side wall


128


.




Referring to

FIG. 7

, still another alternate embodiment of the pivot


250


is formed as a projecting plug


252


in the side wall


226


of the clip


224


. Again, an opening


256


is formed in the opposing side wall


228


in projection fashion to the plug


252


. The plug


252


is formed integral with the side wall


226


and is connected thereto by relatively thin, frangible sections


254


. In this manner, when the clip


224


is placed over the package


10


and appropriately positioned (as will be discussed in detail below) the plug


252


can be readily urged or pushed from the side wall


226


through the fin


18


and into the opposing side wall opening


256


. In a contemplated embodiment, the opening


256


formed in the opposing side wall


228


has tapered surfaces


256




a,b


that taper inwardly toward the outer portion of that side wall


228


. In this manner, when the plug


252


is urged through the fin


18


and into the opposing side wall


228


, a friction fit is established at that side wall


228


to maintain the plug


252


properly positioned and secured on the fin


18


.




Other pivot arrangements will be recognized by those skilled in the art, which other arrangements are within the scope and spirit of the present invention.




Optionally, as seen in

FIG. 9

, the clip


24


can include an arrangement by which an audible indication, such as a click, provides that the clip


24


has been fully urged on to the fin panels


18


. In a contemplated embodiment, the clip


24


can include flexible, finger-like elements


58


extending inwardly from the side walls


26


,


28


into the central portion of the clip


24


. These flexible finger-like elements


58


, when flexed as a result of passing over the fin panels


18




a,b


can be configured to provide this audible “click” to indicate that the clip


24


is properly secured on to the fin


18


. Also optionally, as seen in

FIG. 10

, the clip


24


can be configured having one or more retaining members or detents


60


proximal to the pivot


50


location to maintain the clip


24


in an open position when the spout


22


is opened. To this end, the retaining detents


60


can be configured as projections that extend inwardly from about the free ends


36


,


38


of the clip


24


, near the pivot


50


location so that they interfere with the clip


24


if it inadvertently “falls” back on to the fin


18


when the carton


10


is open and in use.




In one embodiment, as discussed above, and as seen in

FIG. 8

, the throat area


40


is constricted relative to the space between the side walls


26


,


28


near the bridge wall


34


. This provides greater pressure or compression on the fin panels


8




a,b


at a location close to the gable panels


16


. Optionally, as seen in

FIG. 11

, one or more serrations or gripping elements


62


can be formed on the inner surfaces


64


,


66


of the side walls


26


,


28


. This too provides positive securing of the clip


24


to the fin


18


when in place.




As seen in

FIGS. 12 and 13

, the present clip


24


can be used on a variety of different sizes of gable-top packages


10


. To this end, it is contemplated that a single size clip


24


can be used for most standard gable-top carton packages


10


. For example,

FIG. 12

illustrates the top and fin portion


18


of a standard gable-top package


10


(having a substantially square cross section) and in which the inner fin panels


18




c,d


and


18




e,f


essentially abut one another when the package


10


is sealed. The clip


24


is positioned on the package


10


such that the pivot


50


extends through the fin


18


at a portion that is spaced from those panels


18




c,d


that ultimately open to form the spout


22


. This is necessary so that the pivot


50


does not interfere with opening the panels


18




c,d


that form the spout


22


. To this end, a hole or opening


68


is formed in the fins


18


for receiving the pivot


50


. As will be recognized by those skilled in the art, the opening


68


can be formed in the carton material during the converting process. Alternately, the opening


68


can be formed, such as by punching or cutting after the carton


10


has been filled and sealed.





FIG. 13

illustrates the top and fin


118


portion of a carton


110


in which the inner gable panels


118




c,d


and


118




e,f


do not extend all the way to a center line C


110


of the package


110


. This would, perhaps, be the case in which a package


110


has a rectangular, rather than a square cross-sectional shape. In such a case, the pivot


50


can extend through only the exterior gable fin panels


118




a,b


. To this end, the clip


24


does not have to be as long as the entirety of the fin panels


118




a,b


and can, in fact, be considerably shorter in that back or rear end of the clip


24


does not have to extend all the way to or near an end of the fin


118


. In such a configuration, the clip


24


will likely not pivot 180 degrees from the open position to the closed position, but will lie at an upward angle relative to the fin


118


. As such, this embodiment


24


can include the retaining members


60


(best seen in

FIG. 10

) to maintain the clip


24


up and away from the dispensing opening


122


when in use.




Although it is contemplated that the present clip-type closure


24


is permanently affixed to the gable-top carton, it can also be configured as an after-market element


324


that is affixed to a carton


10


prior to use. Referring to

FIG. 13

, the clip


324


can include a first base portion


372


that is snuggly fitted on to the carton fin


18


and a pivotal portion


374


that is as described above. In this manner, the closure


324


can be used on a carton


10


until the carton is emptied and can subsequently be removed and replaced onto a subsequent or next carton package for use.




As described above, it is contemplated that the present closure


24


-


324


will be formed as a molded product, such as by injection molding. Material such as styrene or the like can be used for making the closure. Such materials are relatively light weight and sufficiently strong to provide the necessary gripping or compression force on the fin panels


18




a,b


,


118




a,b


when the closure or clip


24


-


324


is positioned thereon for resealing the carton


10


,


110


. Other materials will be recognized by those skilled in the art which the other materials are within the scope and spirit of the present invention.




In the present disclosure, the words “a” or “an” are to be taken to include both the singular and the plural. Conversely, any reference to plural items shall, where appropriate, include the singular.




From the foregoing it will be observed that numerous modifications and variations can be effectuated without departing from the true spirit and scope of the novel concepts of the present invention. It is to be understood that no limitation with respect to the specific embodiments illustrated is intended or should be inferred. The disclosure is intended to cover by the appended claims all such modifications as fall within the scope of the claims.
