Description
FIELD OF THE INVENTION
[0001] Certain embodiments of the present invention relate to
reducible and reclosable locking containers for keeping bagged
items fresh and/or for preventing items contained within the
container from spilling out.
BACKGROUND
[0002] In many instances, products are packaged in quantities that
are greater than a single serving or use, such that the product
container is not completely emptied after being opened. It is
desirable for the consumer to be able to efficiently store the
product for later use, and in the case of food products, prevent
the unused portion from becoming stale or otherwise
undesirable.
[0003] For example, many food products currently on the market are
provided in a sealed bag that is contained within a paperboard box.
The typical box has a tab and slot configuration on its lid located
at the top of the box for closing the box, but the configuration
does not prevent the contents from becoming stale or spilling out.
Consumers typically roll the inner bag down and "stuff" the bag
inside the box. There is not a seal on the bag or any other way to
prevent moisture from entering the bag and spoiling the food.
[0004] The tab and slot configuration is also not a sturdy locking
mechanism because it does not secure the open bag in place or close
the top of the bag. If the box were to tip over in the cupboard
after being opened, its contents could easily spill out. This is
the case whether the product is a food item such as cereal,
crackers, or cookies, or a household item, such as laundry
detergent or fertilizer.
[0005] Products are also packaged in boxes or containers that are
large enough to hold the full amount of the item being packaged,
but that end up being too large for the remaining product once a
serving or two has been removed. Reduction in container size once a
certain amount has been used would increase available storage
space.
[0006] Accordingly, there is a need to provide a re-closable
container that can be reduced in size once a predetermined amount
has been removed from the container. Additionally, because existing
packaging does not provide a way to secure an open bag within a box
to keep the contents fresh or prevent them from spilling, there is
a need to provide a container that allows for re-closing of the box
and fastening of the bag to protect the remainder of the
product.
SUMMARY
[0007] There is provided a re-closable container that can be
reduced in size once a predetermined amount has been removed from
the container. Containers according to certain embodiments provide
a utility flap that can be used to secure a bag in place, to help
prevent moisture from affecting the contents of the container, and
to help provide a secure closure for the container.

DETAILED DESCRIPTION
[0014] FIG. 1 shows a blank 10 according to certain embodiments of
the invention, prior to being assembled. Blank 10 has a front wall
panel 12, a back wall panel 14, and side wall panels 16. It also
includes a glue flap 18 that is preferably used to secure the box
in its assembled box-shaped position. Although glue flap 18 is
shown attached to back wall panel 14, it can alternatively extend
from any edge panel of blank 10. Blank 10 also features a series of
dust flaps 19 that are useful in preventing dust and other
particles from entering the assembled container where the panels
are joined.
[0015] Front wall panel 12, back wall panel 14, side wall panels
16, glue flap 18, and dust flaps 19 are attached to one another by
lines of weakness that allow the panels to be folded relatively
easily with respect to one another during assembly. For the
purposes of this document, "line of weakness" means any area of
weakness formed in blank 10 that allows a consumer or manufacturer
to relatively easily fold a portion of blank 10 without removing
the portion being folded from blank 10.
[0016] Front wall panel 12 features a lower portion 20 and an upper
portion 22. Lower portion 20 has a line of perforation 24, which
forms an insertion slit 26. For the purposes of this document,
"line of perforation" means a score line or other area of weakness
formed in blank 10 that allows a consumer to easily tear away a
portion of blank 10 or puncture blank 10. Insertion slit 26 stays
closed until the consumer presses against the perforation 24 to
form the slit 26. Insertion slit may be located anywhere on front
wall panel 12, may extend between front wall panel 12 and side wall
panels 16, or may be located on side wall panels 16 alone.
[0017] Extending from upper portion 22 of front wall panel 12 is
utility flap 28. Utility flap 28 is preferably joined to front wall
panel 12 by a line of weakness 30 that allows it to be folded
over.
[0018] Utility flap 28 preferably also attached to upper portion 22
of front wall panel 12 by two small lines of perforation 24 that
form tear away strip 32 (described below). Utility flap 28 may
optionally extend the full distance of front panel or may extend a
smaller distance. Although preferably associated with front wall
panel 12, utility flap 28 may be provided anywhere on blank 10 such
that it is allowed to perform the tucking functions described
below. Utility flap 28 is shown as trapezoidal in shape, but it
should be understood that it may be any shape that allows it to
perform the desired tucking function, such as square, triangular,
circular, semi-circular and so forth. Utility flap 28 is also shown
as a single flap, but it should be understood that utility flap may
be multiple flaps or a single flap with multiple panels.
[0019] Upper portion 22 of front wall panel 12 also features a
locking tab 34. In use, locking tab 34 is adapted to cooperate with
insertion slit 26 to close container, as will be described more
fully below. Locking tab 34 may be any shape or size and may be
located anywhere on carton, as long as it provides the desired
closure function. For example, it is possible for the edges of new
lid 60 (described further below) to provide the desired locking
tabs 34. Additionally, locking tab and insertion slit may have
their locations reversed such that locking tab is on the lower
portion 20 of front wall panel, extending between front wall panel
12 and side wall panels, or on side panels 16 alone 12 and
insertion slit is on the upper portion 22.
[0020] Locking tab 34 is shown as a single tab, but it should be
understood that locking tab may be multiple tabs. There may also be
provided one or more locking tab and slit combinations. Locking tab
and slit need not be positioned on the center of container 100, but
may be positioned at the edges of container or be otherwise
offset.
[0021] FIG. 4 shows utility flap 28 and locking tab 34 in their
formed position once the container 100 (that is ultimately formed
from blank 10) is assembled and opened by removal of the tear away
strip 32 described below.
[0022] Referring back to FIG. 1, also extending from upper portion
22 of front wall panel 12 is tear away strip 32. (In some
embodiments, however, tear away strip 32 is not connected to front
wall panel 12. It may extend from lid panel 36a only.) Tear away
strip 32 is provided to allow the container 100 that is ultimately
formed from blank 10 to be provided in a typical box-type shape, as
shown in FIGS. 2-6. The consumer removes and discards tear away
strip 32, shown in cross-hatchings in FIGS. 3 and 4, to access the
contents of container. It should be understood that rather than
discarding tear away strip 32, tear away strip 32 may be printed
with promotional tools, including coupons or game pieces. As
discussed above, removal of tear away strip defines utility flap 28
and locking tab 34.
[0023] At the top of front wall panel upper portion 22 is lid panel
36a. Lid panel 36a (along with 36b) forms the top lid of container
100 in the container's assembled position, as shown in FIG. 3. Once
box 100 is opened and collapsed, lid panel 36a forms the front lid
36 of container 100, as shown in FIGS. 4 and 5.
[0024] Returning back to FIG. 1, back wall panel 14 preferably has
a lower portion 38 and an upper portion 40. Lower portion 38 and
upper portion 40 of back wall 14 are separated by a line of
weakness defining a hinge 42. Upper portion 40 is further divided
by another line of weakness 30 defining back lid panel 44 and upper
lid panel 36b. Upon assembly, upper lid panel 36b and lid panel 36a
are glued to form lid 36 (as shown in FIG. 2). Base panels 52a and
52b extend from front wall panel 12 and back wall panel 14.
[0025] Side wall panels 16 connect front wall panel 12 and back
wall panel 14. Side wall panels 16 have lower portions 46 and upper
portions 48. Lower portions 46 of the side walls 16 form the main
wall area and upper portions 48 form closure flaps 50 upon removal
of tear away strip 32 and assembly of blank 10.
[0026] Blank 10 is preferably formed of paperboard, fiberboard,
chip board, corrugated or any other easily assembled material.
Multiple blanks 10 may be shipped to the food producer in their
flat form for assembly and filling on site.
[0027] In order to assemble blank 10, front wall panel 12, side
wall panels 16, back wall panel 14 are folded to form a rectangular
box. Glue or any other adhesive substance or securing mechanism
secures glue flap 18 and the other panels in place. Base panels 52a
and 52b are also glued or otherwise adhered to one another and
lower dust flaps 19 (if provided) are secured.
[0028] At this point, a box 100 with an open top is provided, as
shown in FIG. 2. Typically, the box will be filled with a bagged
food product 54, such as cereal, crackers, or cookies, although it
is also possible to fill it with other items in bags, such as
laundry detergent, fertilizer, or any other item as desired.
[0029] Once inner portion of box 100 is filled with the bagged
product 54, lid panels 36a and 36b are preferably glued or
otherwise adhered to one another to form lid 36, and dust flaps 19
are then glued or otherwise adhered to cover the fold joints
formed. This provides a container like that shown by FIG. 3.
[0030] Upon purchase or receipt of the product container, a
consumer will remove tear away strip 32 to open the container 100,
as shown in FIG. 4. A new lid 60 is now formed by back lid panel 44
(upper portion 40 of back wall), lid panels 36a and 36b, and
closure flaps 50 of the side walls 18. The lid 60 also features
locking tab 34 that is defined upon removal of tear away strip 32.
Front panel 12 also features utility flap 28.
[0031] Once the bagged product 54 is opened and used, the consumer
may fold the new lid 60 back along hinge 42 and replace the bag, as
shown in FIG. 5. Once the bag 54 is placed inside container, its
open end 56 should be placed over utility flap 28 and optionally
may be crimped over utility flap. Some users may wish to use a bag
clip or a paperclip or other closure device to fully secure bag to
utility flap 28, although this is not necessary. After open end 56
of the bag has been folded over the utility flap 28, the utility
flap 28 and bag are folded forward and against front wall panel 12,
securing the bag against moisture and spillage. In other words, the
bag is preferably folded once against the front wall panel 12 of
container, over utility flap 28, and is "pinned" or secured against
the container 100 when the new lid 60 is closed to help prevent
against moisture and spillage. The new lid 60 is folded over and
the locking tab 34 (or tabs) is secured in insertion slit 26 for
closure.
[0032] Container may be printed to provide promotional or marketing
material. According to certain embodiments, it is printed so that
graphics on the box have the same appearance before and after the
box is collapsed. It is also possible, however, the provide new
graphics on the lid panels 36a and 36b that are not seen from the
front view until the container is collapsed and locked.
[0033] Changes and modifications, additions and deletions may be
made to the structures and methods recited above and shown in the
drawings without departing from the scope or spirit of the
invention and the following claims.
