Description
RELATED APPLICATION
[0001] This application claims the benefit of U.S. Provisional
Application No. 60/680,158, filed May 12, 2005, entitled
"Reclosable Carton," the entire contents of which are hereby
incorporated by reference as if presented herein.
BACKGROUND
[0002] Dispensing paperboard cartons are known. The cartons
typically accommodate a flexible bag used to store foodstuffs and
other dispensable items. Conventional cartons have a top panel
formed from four glued flaps that are separable to open a top
portion of the carton. The bag can be opened and the contents of
the carton dispensed from the opened carton, top. The top panel,
however, when reclosed, may not provide a sufficiently tight seal
for the contents of the bag. Conventional paperboard cartons also
occupy a fixed volume that is determined by the amount of product
held within the carton upon initial sale. When a portion of the
product held within the carton is consumed, the carton continues to
occupy a relatively large storage space, which may be limited, to
store a reduced amount of product.
SUMMARY
[0003] According to a first exemplary embodiment of the invention,
a carton comprises a first side panel, a first end panel, a second
side panel, a second end panel, a top panel, a bottom panel, a
flexible vessel disposed within the carton, and a tear strip
extending around the perimeter of the carton. The flexible vessel
can accommodate, for example, dispensable articles such as
foodstuffs. The tear strip at least partially defines a first
reclosure flap in the first side panel and a second reclosure flap
in the second side panel.
[0004] According to one exemplary aspect of the first embodiment,
the tear strip can be removed in order to separate the carton into
an upper section and a reclosable lower section. Removing the upper
section of the carton allows access to the flexible vessel
accommodated within the reclosable lower section, from which a user
can dispense product stored in the vessel. When the user has
dispensed a desired amount of product from the flexible vessel, the
open upper part of the vessel can be pressed between the first
reclosure flap and the second reclosure flap, and the reclosure
flaps pivoted inwardly toward one another with the upper part of
the vessel held therebetween. The reclosure flaps secure the opened
upper end of the vessel and provide a relatively tight seal for the
vessel's open end. The reclosure flaps can be selectively opened to
dispense further vessel contents and subsequently reclosed.
[0005] According to another aspect of the first embodiment, the
height of the carton can be reduced by removing the upper section
of the carton. The carton may be reduced in height when, for
example, a portion of the contents of the carton have been consumed
or otherwise dispensed. The remainder of the contents, which are
accommodated within the reclosable lower section of the carton, are
thereby stored in a carton which occupies less space than the
original carton. The reduced size of the carton also allows a
consumer to visually evaluate the reduced amount of product
remaining in the carton, which may serve as cue to purchase more
product.
[0006] Those skilled in the art will appreciate the above stated
advantages and other advantages and benefits of various additional
embodiments reading the following detailed description of the

DETAILED DESCRIPTION
[0018] The present embodiments are addressed to a carton that is
separable into an upper section and a reclosable lower section. The
reclosable lower section may accommodate a flexible vessel that is
accessible after the upper section is removed, and includes a
reclosure feature that allows an upper portion of the flexible
vessel to be relatively tightly closed after opening. In this
specification, the terms "lower," "upper," "side," "bottom," and
"top" indicate orientations determined in relation to a fully
erected, upright carton.
[0019] FIG. 1 is a plan view of a first, interior side of a blank 8
used to form a carton 150 (illustrated in FIG. 3) according to a
first embodiment of the invention. The blank 8 comprises a first
end panel 10 foldably connected to a first side panel 50 at a first
transverse fold line 51, a second end panel 70 foldably connected
to the first side panel 50 at a second transverse fold line 71, and
a second side panel 100 foldably connected to the second end panel
70 at a third transverse fold line 101.
[0020] The first end panel 10 is foldably connected to a first end
top flap 16 and a first end bottom flap 18. The first side panel 50
is foldably connected to a first side top flap 56 and a first side
bottom flap 58. The second end panel 70 is foldably connected to a
second end top flap 76 and a second end bottom flap 78. The second
side panel 100 is foldably connected to a second side top flap 106
and a second side bottom flap 108. The top flaps 16, 56, 76, 106
extend along an upper or top marginal area of the blank 8 and may
be foldably connected at an upper longitudinally extending fold
line 82. The bottom flaps 18, 58, 78, 108 extend along a lower or
bottom marginal area of the blank 8 and may be foldably connected
at a lower longitudinally extending fold line 84. The longitudinal
fold lines 82, 84 may be straight fold lines, or may be offset at
one or more locations to account for, for example, blank thickness
or other factors. When the carton 150 is erected, the top flaps 16,
56, 76, 106 close a top opening of the carton 150, and the bottom
flaps 18, 58, 78, 108 close a bottom opening of the carton 150
(illustrated in FIG. 3).
[0021] According to one exemplary aspect of the present invention,
the blank 8 includes a tear strip 40 that divides the first end
panel 10 into upper and lower first end panel sections 12, 14, the
first side panel 50 into upper and lower first side panel sections
52, 54, the second end panel 70 into upper and lower second end
panel sections 72, 74, and the second side panel 100 into upper and
lower second side panel sections 102, 104. An adhesive panel 112
may be foldably connected to the upper second side panel section
102, and adhesive panels 114, 116 may be foldably connected to the
lower second side panel section 104. A longitudinal fold line 62
extends along the length of the blank 8, and defines a bottom edge
of a first reclosure flap 64 in the lower first side panel section
54. The longitudinal fold line 62 also defines a bottom edge of a
second reclosure flap 66 in the lower second side panel section
104. The tear strip 40 defines the upper edges of the first and
second reclosure flaps 64, 66, and may include a pull tab 42
defined by at least one tear line 44.
[0022] The first end panel 10 includes a first reclosure pattern 20
at an upper portion of the first lower end panel section 14. The
second end panel 70 includes a second reclosure pattern 80 at an
upper portion of the second lower end panel section 74. The first
and second reclosure patterns 20, 80 comprise lines of disruption
that allow the end panels 10, 70 to deform in order to facilitate
reclosable sealing of the carton, as discussed in detail below. In
the exemplary embodiment, the first reclosure pattern 20 includes a
longitudinal or horizontal cut/crease line 24 and a transverse or
vertical cut/crease line 26 that intersect one another in the first
end panel 10. Oblique crease lines 22 form an inverted V-shape over
the intersecting cut/crease lines 24, 26. Similarly, the second
reclosure pattern 80 includes intersecting cut/crease lines 84, 86
and crease lines 82 arranged in an inverted V-shape.
[0023] Each end panel 10, 70 includes a respective transverse or
vertical crease line 19, 79 extending from the vertical cut/crease
lines 26, 86, respectively, to the longitudinal fold line 84. The
crease line 19 extends vertically through the first end panel 10
and intersects with a V-shaped crease line 30 near the bottom of
the first end panel 10. The crease line 79 extends vertically
through the second end panel 70 and intersects with a V-shaped
crease line 90 near the bottom of the second end panel 70. The
crease lines 19, 79, 30, 90 also facilitate reclosure of the first
and second reclosure flaps 64, 66, as discussed in further detail
below.
[0024] The first side top flap 56 can include a closure tab 60 that
is sized to be received in a closure slit 110 formed in the second
side top flap 106. The closure tab 60 and closure slit 110 provide
for an optional method of reclosable sealing of the carton 150
(illustrated in FIG. 3) after the top panel of the carton is
opened.
[0025] An exemplary process of erecting the carton 150 from the
blank 8 will now be discussed with reference to FIGS. 1-4.
Referring to FIGS. 1 and 2, glue or other adhesive is applied to
the adhesive panels 112, 114, 116 on the exterior side of the blank
8. The adhesive can be, for example, liquid glue, glue strips, or
other materials. The blank 8 is then folded so that the exterior
sides of the adhesive panels 112, 114, 116 adhere to the interior
side of the first end panel 10. The glued blank is then opened to
have the closed, generally tubular form shown in FIG. 2.
[0026] FIG. 3 is a front perspective view of the erected carton
150. Referring also to FIG. 2, the carton 150 is fully erected when
the top flaps 16, 56, 76, 106 are folded over and adhered to form a
top panel 160, and the bottom flaps 18, 58, 78, 108 are folded over
and adhered to form a bottom panel 170. A bag 140 (illustrated in
FIGS. 8 and 11) or other flexible vessel may be inserted in the
carton 150 in a conventional manner at any time before closing the
flaps 16, 56, 76, 106, 18, 58, 78, 108. The bag 140 may be filled
with product and then inserted into the carton, or, the bag 140 may
be inserted empty and filled with product afterwards. The tear
strip 40 may extend around all or substantially all of the
perimeter of the carton 150.
[0027] In an optional method of opening and reclosing the carton
150, the top panel 160 of the carton 150 can be opened by pulling
up on the top flap 56 and breaking the connection to the top flap
106. The opened top panel 160 can be subsequently reclosed by
engaging the closure tab 60 with the closure slit 110. FIG. 3
illustrates the top panel 160 in a reclosed state, with the closure
tab 60 inserted in the closure slit 110. The top panel 160 can be
selectively opened and closed, for example, in order to dispense
product from the flexible vessel 140 (illustrated in FIGS. 8 and
11) accommodated within the carton 150.
[0028] FIG. 4 is a partial end view of the carton 150 illustrating
a portion of the first end panel 10 and the tear strip 40. The tear
strip 40 with pull tab 42 is disposed adjacent to the top of the
inverted V-shaped crease lines 22 of the first reclosure pattern
20, with the pull tab 42 extending from the corner of the carton
150 so that it may be easily grasped. The cut-crease line 26 and
the crease line 19 extend generally vertically through the first
end panel 10. Similarly, at the second end of the carton 150 (not
shown in FIG. 4), the cut-crease line 86 and the crease line 79
extend vertically through the second end panel 70.
[0029] A method of opening and reclosure of the carton 150 will now
be discussed with reference to FIGS. 5-11. According to the method
illustrated in FIGS. 5-11, the carton 150 can be selectively opened
and reclosed so that the contents of a bag 140 or other vessel
accommodated within the carton 150 may be dispensed and then
securely retained in a reclosable section of the carton.
[0030] Referring to FIGS. 5 and 6, the tear strip 40 is grasped at
the pull tab 42 and pulled away from the surface of the carton 150.
The tear strip 40 is then pulled around the entire perimeter of the
carton 150. The upper section of the carton 150 located above the
tear strip 40 can now be separated from the lower section of the
carton and discarded along with the tear strip.
[0031] FIG. 7 is a partial top perspective view of the carton 150
with the tear strip 40 removed, and the upper section of the carton
150 discarded. A reclosable lower carton section 200 of the
original carton 150 remains. For illustrative purposes, the bag 140
disposed within the reclosable lower carton section 200 is not
shown in FIG. 7.
[0032] The bag 140 can accommodate, for example, foodstuffs and
other dispensable product. Referring to FIGS. 7 and 8, with the
upper section of the carton 150 removed, the bag 140 can be opened
and the contents of the bag can be accessed and/or dispensed from
the open top of the lower section 200. After a desired amount of
product is dispensed, the reclosable lower section 200 can be
reclosed to seal the bag 140. Reclosure of the lower section 200 is
discussed below with reference to FIGS. 8-11.
[0033] Referring to FIG. 8, the reclosure process is illustrated at
the lower first end panel 14 end of the reclosable lower section
200. The lower second end panel 74 at the opposite end of the lower
section 200 undergoes the same process when reclosing the lower
section 200. Reclosure is initiated by pulling the lower first end
panel 14 outwardly at the reclosure pattern 20, so that the lower
first end panel 14 deforms outwardly at the cut-crease line 26
(illustrated in FIG. 1) and also bends at the lines 22, 24. The
lower second end panel 74 (not shown) is similarly pulled outwardly
at the reclosure pattern 80 and deforms at the lines 82, 84, 86
(illustrated in FIG. 1). The bag 140 is pressed between the first
reclosure flap 64 (not shown in FIG. 8) and the second reclosure
flap 66 as the upper portions of the lower end panels 14, 74 extend
outwardly. The folded upper portions of the lower end panels 14, 74
are then pivoted downwardly in the direction of the curved
arrow.
[0034] FIG. 9 illustrates the second end of the lower section 200
during reclosure of the section. The bag 140 is not shown in FIG. 9
or 10 so that folding of the lower end panels 14, 74 is more
clearly illustrated. Referring to FIG. 9, the deformed portion of
the lower second end panel 74 is pivoted downwardly in the
direction of the curved arrow.
[0035] Referring to FIG. 10, as the deformed upper portions of the
lower end panels 14, 74 are pivoted downwardly, the second
reclosure flap 66 rotates inwardly in the direction of the curved
arrow. At the same time, the first reclosure flap 64 pivots
inwardly in the direction of the other curved arrow. The bag 140 is
pressed between the first and second reclosure flaps 64, 66, as
illustrated in FIG. 11.
[0036] Referring to FIG. 11, the bag 140 is tightly pressed between
the underside of the first reclosure flap 64 and the upper side of
the second reclosure flap 66, and extends toward one side of the
section 200 from beneath the first reclosure flap 64. The lower
section 200 is now in its reclosed state, with the upper portion of
the bag 140 held between the first and second reclosure flaps 64,
66 in a relatively tight seal.
[0037] According to one aspect of the above-described embodiment,
the lower carton section 200 can be reclosed with a relatively
tight seal. The seal is particularly advantageous when product held
within the carton is perishable or otherwise sensitive to the
outside environment.
[0038] According to another aspect of the first embodiment, the
height of the carton 150 is reduced when the carton is separated
into the upper and lower sections. Referring to FIGS. 3 and 11, the
height of the carton 150, which may generally coincide with the
height of the side panels 50, 100, is larger than the height of the
bottom carton section 200 in its reclosed state. The height of the
bottom carton section 200 may be, for example, less than about 80%
of the height of the carton 150. Therefore, after a portion of the
carton contents have been dispensed, the remainder of the contents
can be stored in the bottom carton section 200 that occupies less
space than the carton 150. The reduced size of the carton also
allows a consumer to roughly visually evaluate the reduced amount
of product remaining in the carton, which may serve as cue to
purchase more product.
[0039] In the illustrated embodiment, the flexible vessel in the
carton 150 is a bag 140. The bag may be formed from, for example,
plastics or other materials. Other types of vessels, such as paper,
etc. may be used depending upon the nature of the product to be
accommodated within the flexible vessel.
[0040] In the illustrated embodiment, the tear strip 40 is
illustrated as a single continuous filament tear strip that may be
removed in a single operation. The tear strip may, however, be a
segmented strip that is removeable in stages. In practice, any tear
strip form that allows a user to separate the carton 150 into upper
and lower sections may be used. The tear strip may be combined with
100% and/or partial cuts or scores in the blank 8 to facilitate
removal of the tear strip.
[0041] In the illustrated method of reclosing the lower section
200, the second reclosure flap 66 is illustrated as folded under
the first reclosure flap 64, with the bag 140 extending toward the
lower second side panel 104. The lower section 200 may, however,
alternatively be reclosed by folding the first reclosure flap 64
under the second reclosure flap 66. In this method of reclosure,
the bag 104 would extend toward the lower first side panel 54.
[0042] The lower section 200 may, for example, be reclosed without
pressing a flexible vessel between the reclosure flaps 64, 66. For
example, if no flexible vessel were present in the lower section
200, the reclosure flaps 64, 66 could be closed as illustrated in
FIG. 10. Or, a user may elect to tuck a flexible vessel into the
interior of the lower section 200 and close the flaps 64, 66 over
the vessel.
[0043] The blank 8 can be, for example, formed from hard paper,
paperboard and similar materials. In the exemplary embodiment
discussed above, the blank is formed from clay coated newsprint
(CCN). In general, the blank may be constructed of paperboard,
having a caliper of at least about 14, so that it is heavier and
more rigid than ordinary paper. The blank, and thus the carton, can
also be constructed of other materials, such as cardboard, or any
other material having properties suitable for enabling the carton
to function at least generally as described above.
[0044] The first and second sides of the blank can be coated with,
for example, a clay coating. The clay coating may then be printed
over with product, advertising, and other information or images.
The blank may then be coated with a varnish to protect any
information printed on the blank. The blank may also be coated
with, for example, a moisture barrier layer, on either or both
sides of the blank. The blank can also be laminated to or coated
with one or more sheet-like materials at selected panels or panel
sections.
[0045] In accordance with the exemplary embodiments, a fold line
can be any substantially linear, although not necessarily straight,
form of weakening that facilitates folding therealong. More
specifically, but not for the purpose of narrowing the scope of the
present invention, fold lines include: a score line, such as lines
formed with a blunt scoring knife, or the like, which creates a
crushed portion in the material along the desired line of weakness;
a cut that extends partially into a material along the desired line
of weakness, and/or a series of cuts that extend partially into
and/or completely through the material along the desired line of
weakness; and various combinations of these features.
[0046] The above embodiments are described as having one or more
panels adhered together by glue. The term "glue" is intended to
encompass all manner of adhesives commonly used to secure carton
panels in place.
[0047] The foregoing description of the invention illustrates and
describes the present invention. Additionally, the disclosure shows
and describes only selected embodiments of the invention, but it is
to be understood that the invention is capable of use in various
other combinations, modifications, and environments and is capable
of changes or modifications within the scope of the inventive
concept as expressed herein, commensurate with the above teachings,
and/or within the skill or knowledge of the relevant art.
