Description
SUMMARY OF INVENTION
This invention relates generally to a container for packaging two
different products. The products may be considered primary and
secondary where only two are involved, however, the container could
be adapted for housing several different products by employing the
same inventive technique.
More specifically, the invention pertains to a container for
shipping and dispensing at least two different products which for
the sake of convenience must be retained in a single package. The
container is designed to accomplish this result by providing a
primary large outer carton which has a proportionally sized
compartment formed therein for accommodating a smaller inner
carton. The compartment in the outer carton is formed by bracing
and positioning bridge-like panels for accepting the inner carton.
Another feature of the container resides in the easy opening top of
the primary carton whereby the secondary carton may be removed
leaving an open area for primary product flow control and
pouring.
Prior to the development of this container, there was not available
on the market a means for accomplishing the desired results. The
packages commonly found were bulky, inconvenient to handle and use,
and did not satisfactorily maintain separation of the various
packaged products. In the usual form these packages comprised
merely a main carton in which the various products were loosely
placed, or such a carton which contained loosely placed receptacles
for the various packaged products. Due to the handling these
packages inevitably received, with no satisfactory means to prevent
displacement and intermixing of the products contained therein,
there frequently resulted a most unattractive and unusable end
product.
Other prior art containers of this type included those formed from
a one piece blank and others which were formed from two individual
blanks with the individual cartons secured to one another by
cooperating tabs and slots. At least one prior device included a
plural compartment container wherein one compartment was accessible
only by destruction of the container.
With the novel container of the present invention, each of the
prior art deficiencies have been overcome. The herein described
shipping and dispensing container is constructed from any suitable
material such as, paperboard, corrugated paperboard, plastic or
other like material and is formed from two distinct blanks which
are cut and scored in the desired manner. The outer larger carton
includes a two part bridge-like interior panel for retaining and
positioning the inner smaller carton in a prescribed,
proportionally sized compartment.
As an example of the different types of products susceptible to
being packaged in the novel container, the most generally adaptable
products would include a dry food product such as rice or noodles
packed loosely in the outer carton, and a wet food product such as
tomato sauce or gravy in a can in the inner smaller carton.
Similarly, a dry soap product and a wet bleach could be packaged in
the same container with the wet product located in a bottle or can
housed in the smaller inner carton. The different products could
also take the form of a product and a prize or bonus to be used for
advertising purposes.
It will become readily apparent that the novel container described
more specifically in the detailed description herein serves to
safely and securely package different products in a single
container. In addition to the advantages and features discussed
above, numerous other advantages and features will be apparent with
reference to the drawing which forms a part of this specification,
and in which:
BRIEF DESCRIPTION OF THE DRAWING
FIG. 1 is a plan view of a flat paperboard blank from which the
outer carton of this invention is folded;
FIG. 2 is a plan view of a flat paperboard blank from which the
inner carton of this invention is folded;
FIG. 3 shows the inner carton erected and ready to be inserted into
the primary carton;
FIG. 4 is a perspective view partly in section showing the primary
carton inner compartment;
FIG. 5 is a perspective view similar to FIG. 4 but taken on a
different angle; and
FIG. 6 shows the two cartons nested together.
DETAILED DESCRIPTION
The container of the present invention takes the form of two flat,
cut and scored blanks of paperboard or the like which blanks are
adapted to form the primary and secondary cartons referred to
hereinbefore. The primary carton, or outer carton would be sized to
accommodate the product to be shipped and the blank forming the
primary carton would include panels for forming an integral
proportionally sized inner compartment for accepting the secondary
carton.
FIG. 1 shows in blank form a typical blank which could be used to
fabricate the outer or primary carton. A series of panels 10, 12,
14 and 16 separated by fold lines 11, 13 and 15 make up the
conventional four sidewalls of an ordinary container. Attached
along the opposite free edge of the side panel 16 there is located
the additional panels necessary to form the secondary product inner
compartment. These latter panels are suitably shaped, cut and
scored to form the inner compartment sidewalls and a supporting
element or shelf for the secondary carton.
In particular, attached to side panel 16 along fold line 17, there
is located a glue panel 18 which is scored to form an odd shape and
which is ultimately glued to the inside of sidewall panel 10 to
form the basic outer carton shape. The odd shape of flue panel 18
in the preferred embodiment is formed by applying to the glue panel
18 a cut line 26 for approximately one-half the width of the panel.
It should be apparent that the cut line 26 could be either raised
or lowered from its illustrated position to accommodate a shorter
or taller secondary carton. Extending from the end of cut line 26
and down to the base of glue panel 18 is a fold line 25, which,
together with the portion of cut line lying in panel 18 and fold
line 19 on the opposite side of panel 18, forms a stair step
configuration in blank form. In the constructed container, the cut
line 26 forms the upper part of the bridge-like partition panel 24
which serves to support the secondary carton in its proportionally
sized compartment. The partition panel 24 is bounded by fold line
25 which, in the illustrated embodiment, bisects the width of glue
panel 18, and fold line 23 which forms one side of a second glue
panel 22. The second glue panel 22 is oppositely shaped from that
of glue panel 18 by a continuation of cut line 26 which extends
approximately one-half the width thereof. Extending from the end of
cut line 26 in glue panel 22 to the top of the blank is a fold line
21 which together with the cut line 26 and fold line 23 forms
another stair step configuration in blank form.
Thus it should be apparent that the extension of the basic blank
for the primary carton comprises four individual panels 18, 20, 22
and 24, two of which 18 and 22, are glue panels. The remaining
panels 20 and 24 comprise the basic elements which form the
proportionally sized inner compartment and the means for supporting
the secondary product carton within the primary carton. The inner
compartment walls become panel 20, a portion of glue panel 18, the
sidewall panel 16 and the portion of the backwall panel 14. Panel
24 becomes in the completed carton a bridge-like shelf member which
supports the secondary carton within the inner compartment. This
panel need not be so constructed as to lie directly under the inner
compartment, but it may be offset if desired by simply reorienting
the fold lines 23, 25.
In addition to the conventional panel walls 10, 12, 14 and 16 for
forming the basic primary carton, conventional bottom closure flaps
are provided along the lower edge of the blank for sealing the
bottom of the carton. Closure flaps 28, 30, 32 and 34 are
illustrated as being foldably connected along fold lines 27, 29, 36
and 37 to their respective panel walls. Flaps 28 and 30 are
separated by a cut line 31 while flaps 30 and 32 are separated from
one another by a cut line 33. Similarily, flaps 32 and 34 are
separated by a cut line 35. The bottom closure flaps are capable of
being glued, stapled or stitched to seal the bottom of the primary
carton in any convenient or practical manner.
Attached to the top edge of the conventional panel walls 10, 12, 14
and 16 are top closure flaps for releasably sealing the top of the
primary carton. Top closure flaps 40, 44 and 48 are shown as being
foldably attached to their respective panels along fold lines 41,
45 and 47. For convenience in opening the primary carton and to
provide access to both the inner compartment and the contents of
the primary carton, the top closure flaps 40 and 48 are each scored
to permit ease of entry. Flap 40 includes a second portion 38 which
is separated from flap 40 along fold line 39 and from panel 10
along perforated line 42. The perforated line 42 is a part of fold
line 41 and allows the second flap portion 38 to be folded back
about fold line 39 for entry into the carton. Flap 48 includes a
second portion 50 separated from the main portion of flap 48 by a
fold line 49. Attached to the opposite free edge of second portion
50 is a closure panel and flap combination including panel 52
separated from second portion 50 by fold line 53 and a flap 54
separated from panel 52 by a fold line 55. The second portion 50 of
flap 48 is also separated from panel 14 by a perforated line 51
which is a part of fold line 47.
When the primary container is erected and filled, it is finally
sealed by means of the glue panel 52 overlapping the side panel 16.
This closure leaves tab 54 free to be used as a lever for opening
the container. When tab 54 is pulled to break the seal along panel
52, the corresponding portion 38 of flap 40 along with portion 50
of flap 48 each are allowed to be torn away from their respective
panels 10 and 14 along the perforated lines 42 and 51. In this
manner entry to the contents of the carton is accomplished. This
method for opening the outer carton is deemed the preferred
embodiment since the panels 52, 54 could be omitted if desired.
The secondary carton which is adapted to fit into the
proportionally sized inner compartment of the primary carton is
shown in detail in FIG. 2. This carton includes side, front and
back walls 56, 58, 60 and 62 separated from one another by fold
lines 57, 59 and 61. Attached to the free edge of sidewall 62 is a
sealing flap 64 separated from wall 62 by a fold line 63.
Conventional bottom closure flaps 72, 76 and 80 are shown attached
to the side and front walls 56, 58 and 60 along fold lines 73, 83
and 87. The flaps 72 and 80 are folded initially with flap 76 being
folded last to seal the bottom. Flap 76 is provided with a tuck tab
78 separated therefrom by fold line 79 which is tucked into the
secondary carton to accomplish the completed closure.
Similarly the secondary carton is provided with conventional top
closure flaps 66, 70 and 82 separated from their respective side
and rear walls 56, 60 and 62 along fold lines 65, 69 and 85. These
top closure flaps function in the same manner as the above
identified bottom closure flaps with flaps 82 and 70 being
initially folded and flap 66 folded last. Flap 66 includes a tuck
tab 68 separated therefrom by a fold line 67 for finally securing
the top. In addition to these closure flaps, the front wall 58 of
the secondary carton includes a pull tab 74 separated from the wall
58 by a fold line 75. This tab 74 could also be incorporated with
the wall 62 where desirable. In the operative condition, the tab 74
is left on the outside of the secondary carton, but folded adjacent
the top closure flap 66. When the secondary carton is placed in the
primary carton inner compartment, the tab 74 remains exposed until
the primary carton is sealed. Ultimately, when the primary carton
is opened, after being filled and sealed, the tab 74 then becomes
reexposed and serves as a means for lifting the secondary carton
out of the primary carton inner compartment.
To more clearly show the relationship between the primary and
secondary cartons, particular attention should be directed to FIGS.
4 and 5. In these two views, the inner compartment of the primary
carton is clearly shown, ready to accept the formed secondary
carton shown in FIG. 3.
FIG. 4 shows the finally assembled primary carton with portions
broken away to show the walls of the inner compartment including a
portion of the backwall panel 14, the end wall panel 16, the glue
panel 18 and the partition panel 20 separating glue panel 18 and
glue panel 22. In this view the glue panel 22 is shown as being
secured to the inside of backwall panel 14 so that the bridge
member 24 occupies a position approximately in the center of the
inner compartment. The glue panel 18 is secured to the inside of
front wall panel 10 so that bridge member 24 effectively prevents
the front and back walls 10 and 14 from bulging. Of course bridge
member 24 also serves as the bottom support shelf member for the
secondary carton once it is slipped into the primary carton inner
compartment.
FIG. 5 shows in detail the inner compartment, but as viewed from a
different angle. The inner compartment walls 20, 14, 16 and 18 are
again illustrated with bridge member 24 clearly being shown in its
preferred position as located in the center of and directly below
the inner compartment of the primary carton. As pointed out
hereinbefore, the shelf member 24 need not be positioned directly
in the center of the primary carton inner compartment, but it may
be offset to accommodate irregular loads occasioned by the weight
and shape of the contents of the secondary inner carton.
The primary carton and the secondary carton are each preferably
cut, scored, printed and glued before being dispatched to the
customer in a knocked down condition. Conventional fabricating
machinery modified for the required sizes of cartons may be used
since no unique panels are employed. The novelty herein is one of
the particular arrangement of the different panels wherein a two
part bridge is used, elements 20, 24, which are offset from one
another to form an inner compartment sidewall, panel 20, and a
secondary carton support shelf, panel 24.
To form the primary carton, the extension panel scores 19, 21, 23
and 25 would be broken and the extension panel folded 180.degree.
about fold line 17 bringing glue panel 22 in contact to be secured
to the inside of rear panel wall 14. Next the side and front wall
panels 10, 12 would be folded 180.degree. about fold line 13. This
step would allow the previously applied glue on glue panel 18 to
secure the panel 18 to the inside of front wall panel 10. These two
gluing steps would yield a knocked down primary carton which when
erected would form the unique inner compartment illustrated in
FIGS. 4 and 5.
The orientation of the inner compartment sidewalls is assured with
the proper breaking of the previously mentioned extension panel
fold lines 19, 2-, 23, and 25. For example, to erect the carton as
shown in FIGS. 4 and 5, the fold line 19 would be scored and broken
to allow a fold on the inside of the blank while the fold line 21
would be scored and broken to permit a fold on the outside of the
blank. Similarly fold line 25 would be scored and broken on the
inside of the blank and fold line 23 scored and broken on the
outside of the blank. With these steps properly done, the primary
carton when erected would assume the configuration of FIGS. 4 and
5.
In like manner, the carton blank for the secondary product would be
scored and broken to produce the carton configuration shown in FIG.
3. The only requirement for this secondary carton being one of
leaving the tab 74 on the outside to facilitate removal of the
secondary carton from the primary carton inner compartment. This
configuration is shown in FIG. 6 wherein the secondary carton is
correctly oriented for easy removal from the primary carton. The
two cartons thus nested provide the container of this
invention.
This specification has thus described a preferred embodiment of the
container of the invention including the steps necessary for
fabricating the novel inner compartment of the primary carton. It
is to be understood, however, that even though only a preferred
embodiment has been described in detail, numerous changes and
variations could be made in the construction of the container while
retaining the novelty of the invention. For instance, the inner
compartment could be made larger or smaller or even divided by an
integrally attached partition member. The bridge element 24 has
been shown as not extending to the bottom of the sidewall panel 16,
and this element could be lengthened or shortened as desired.
Finally, other different forms of top and bottom closure flaps
including regular slotted flaps, overlap slotted, center slotted or
full overlap as shown, could be employed if desired.
