Abstract
A recloseable carton produced from a paperboard blank and having
an easy opening tear tab closure flap is disclosed. When the tear
tab is torn away from the front panel of the carton and the tear
tab and attached cover panel are lifted, a tear-out cover panel and
a tear-out portion of the front panel are exposed which may be
removed, permitting the carton to be reclosed with the cover panel
covering the top of the box and the tear tab tucked along the
interior side of the front panel. Conveniently, the tear-out cover
panel which is torn out may be a coupon integral with the carton
blank and further coupons may be retained between the cover panel
and the tear-out cover panel.

Description
This invention relates to cartons and more particularly to cartons
produced from a paperboard blank, the carton having recloseable
cover means which is initially releasably sealed and when opened,
exposes a tear-out cover panel which, after being removed, permits
the cover means to be closed again and be frictionally retained in
the closed position.
More specifically, the carton construction includes a closure flap
only part of which is glued to a panel of the carton, the glued
portion of the flap being separated from another portion of the
flap called a tuck panel, by a tear line, such that the tuck flap
can be easily separated from the glued portion of the closure flap
by the user. Also the carton is provided with a tear-out panel
beneath an exterior cover panel. After the cover panel is opened
for the first time, the tear-out panel must be torn out to gain
access to the contents. The cover panel is then recloseable with
the tuck flap being inserted interiorly of the carton panel to
which it was originally glued.
The carton construction is ideally designed to include integral
coupons which may be removed and redeemed by the user.
In the merchandising of certain types of articles or commodities,
it is frequently desirable to include with each package one or more
coupons for promotional purposes. The coupons may be used by the
consumer in trade for premiums, to obtain a reduction in price of
another product produced by the same manufacturer, etc. When
packaging articles in paperboard cartons, savings are realized by
the manufacturer if the coupons are an integral part of the
paperboard carton and are detachable therefrom. The coupon may be
printed simultaneously with other printing on the exterior of the
paperboard blank. Frequently, with such arrangements, it is
necessary for the consumer to mutilate the carton when tearing out
the coupon from a panel thereof. Thus, the consumer must wait until
he is ready to use the article or has consumed the contents thereof
before he can remove the coupon, and once the coupon is removed,
the carton has been mutilated and he no longer is able to use the
carton for storage of the contents.
Frequently, when it is desirable that the paperboard carton be of
the recloseable type, the manufacturer has attached the coupon to
the exterior of the carton rather than making it an integral part
thereof so that the carton will not need to be destroyed to remove
the coupon. The disadvantage with such an arrangement is that, in
handling, the coupon frequently becomes detached and lost and in
some instances customers will pilfer the coupons from the cartons
on the shelves of self-service type stores without purchasing the
merchandise. Thus the present invention offers the advantage of a
carton of the recloseable type which has integral coupons which can
be moved without destroying the subsequent usefulness of the
carton.
Though this invention is not limited to carton constructions which
include coupons, the present construction does in fact lend itself
well where coupons are required to be an integral part of the
carton blank yet removable without damaging the carton after the
carton is opened.
An object of the present invention is to provide a paperboard
carton produced from a blank which is easily opened and is
recloseable.
A further object of the invention is to provide a paperboard carton
produced from a blank having integral therewith detachable panels
which serve as coupons.
A still further object of the invention is to provide a recloseable
paperboard carton produced from a blank having integral therewith
one or more detachable panels which may be used as coupons and
which when detached do not deform or mutilate the carton.
A still further object of the invention is to provide a recloseable
paperboard carton having one or more integral coupons which may not
be pilfered or otherwise removed without first opening the
carton.
Another object of the invention is an easy opening tear tab
arrangement whereby no glued areas must be broken away, the glued
areas being separate from the tear tab.
Another object of the invention is to provide easy access to the
tear tab when the carton is to be opened for the first time.
Other objects and features of novelty will be apparent from the
following specification when read in connection with the
accompanying drawings in which certain embodiments of the invention
are illustrated by way of example.
In the Drawings:
FIG 1 is a plan view of a novel one-piece blank from which a carton
embodying the principles of the invention may be erected;
FIG. 2 is a perspective view of an assembled carton produced from
the one-piece blank of FIG. 1;
FIG. 3 is a perspective view of the carton of FIG. 2 as it is
reclosed following opening of the sealed carton; and
FIG. 4 is a perspective view of the carton following opening of the
sealed closure.
Referring to FIG. 1 of the drawings, a novel carton blank is shown
designated by the general reference character 1. The blank is
provided with score lines 2 to form various panels and flaps
including front panel 3, bottom panel 4, back panel 5, cover panel
6, and closure flap 7. Also connected along score lines are side
panels 8 and 9 connected to opposite ends of bottom panel 4 and
dust panels 10, 11, 12 and 13 connected along score lines to
opposite ends of front panel 3 and back panel 5 respectively.
Connected by perforations 36 to front panel 3 opposite bottom panel
4 is a tear-out panel 14 to which are connected by further
perforations 33, 34 and 35 back tab 15 and end panels 16 and 17.
The panel 14 may be in the form of a premium coupon.
The front panel 3 comprises in part a top panel 18 defined by
perforations 31, the top panel being narrower than a tuck panel 20
for reasons which will be apparent later. A slit 19 extends
tranversely away from the midpoint in the perforations 31, the
function of which will be described later.
Closure flap 7 comprises a tuck panel 20 and a pair of sealing
panels 21 and 22 spaced from each other. The sealing panels 21 and
22 are attached to the tuck panel by perforations 23, 24. An
exposed tear edge 25 on tuck panel 20 is provided between the
sealing panels 21, 22 and extends between the ends of perforations
23, 24.
Optionally, an integral coupon 26 may be detachably connected to
cover panel 6 along perforations 27.
In assembling the carton, the blank is folded along the various
fold lines, and back tab 16 is glued to the interior of back panel
5 at the glue area 28. An enclosure is thus formed comprising
bottom panel 4, tear-out panel 14, front panel 3, and back panel 5.
End panels 8 and 16 and dust panels 10 and 12 are then folded and
sealed closing one end of the carton.
Optional coupon 26 is folded along perforations 27 against the
underside of cover panel 6 after which the cover panel is extended
over tear-out panel 14, and closure flap 7 is folded downwardly
over front panel 3 after which sealing panels 21, 22 are glued to
the front panel 3 at glue area 29, 30. It will be noted that since
top panel 18 of front panel 3 is narrower than tuck panel 20,
perforations 31 in front panel 3 are closer to the top of the
carton than perforations 23 in closure flap 7 which closure flap
covers the front panel.
The merchandise is subsequently inserted through the open end of
the container after which end panels 9, 17 and dust panels 11, 13
are folded over the opening and sealed. The finally assembled
carton appears as in FIG. 2.
When the sealed carton is opened, the consumer places his thumbnail
under tear edge 25 of tuck panel 20 peeling back the tuck panel
along perforations 23, 24 separating it from sealing panels 21, 22.
The tear edge 25 is easily accessible between sealing panels 21 and
22, and the tuck panel is easily separated from the sealing panels
since glue for securing the closure flap 7 to front panel 3 is
limited to the sealing panels. The tuck panel 20 and cover panel 6
may then be lifted upwardly exposing optional coupon 26 lying
against the underside of the cover panel and tear-out panel 14
covering the top of the carton. The coupon 26 may be conveniently
removed by tearing along perforations 27, and tear-out panel 14 may
be conveniently removed by inserting a thumbnail under the central
portion of top panel 18 and peeling away the top panel along
perforations 31 separating it from the remainder of the front panel
3 in essentially the same manner as tuck panel 20 is opened.
Conveniently, a slit 19 is provided in front panel 3 permitting
easy access to the leading edge of the top panel 18. The tear-out
panel 14 is then conveniently torn away from end panels 16, 17
along perforations 33, 34 and from back tab 15 along perforations
35 by inserting a thumb through the opening created where the top
panel 18 was located and beneath the tear-out panel 14. This step
is shown in FIG. 4.
Following removal of the tear-out panel, the consumer is ten able
to reclose the carton to store the contents thereof by covering the
opening with cover panel 6 and simultaneously inserting the tuck
panel 20 inside front panel 3 where it is frictionally retained
since the leading edge of the tuck panel extends downwardly below
the top edge of front panel 3. Easy access to tuck panel 20 for
reopening the carton is provided by the opening in front panel 3
where top panel 18 was formerly located.
The tear-out panel 14 serves to securely seal the carton at the
time of packaging and it eliminates the need for end panels to be
secured to the cover panel 6 which would be inserted inside the
opposite ends of the carton. End panels attached to a recloseable
cover are inconvenient as far as the user is concerned since upon
reclosing the cover, the user must manipulate the end panels so
that they descend into the opposite ends of the carton. Frequently
such end panels cannot be inserted easily because, as they descend,
they press upon the contents of the carton which is lying against
the interior surface of the ends of the carton. With the present
invention, the cover may be easily reclosed with no resistance
caused by end panels attached to the cover.
The tear-out panel 14 in addition to securely closing the carton at
the time of packaging, offers the further optional advantage of
serving as a coupon panel which is an integral part of the carton
but can be removed without destroying the usefulness of the carton.
When the tear-out panel is used, as a coupon, it offers the further
advantage of being concealed within the sealed carton such that it
cannot be pilfered except by opening the carton.
It will be readily appreciated that a recloseable carton is
provided which is easily opened without permanently deforming the
closure panels thereby making the carton attractive for continued
use after being opened.
It is understood that various changes and modifications may be made
in the embodiments illustrated and described herein, without
departing from the scope of the invention as defined by the
following claims.
