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.
