Description
BACKGROUND OF THE INVENTION
[0001] The present invention is generally related to containers,
and is particularly related to containers including an inner box
designed to protect an object packaged therein and an outer box
that surrounds the inner box.
[0002] There have been many efforts directed to providing
double-walled or two box containers. U.S. Pat. No. 975,121 to
Carter discloses a double-walled box formed of a single piece of
sheet material having cooperating parts that are arranged to be
folded and interlocked so as to provide two complete integrally
joined boxes, one of the boxes being contained within and protected
by the other box.
[0003] U.S. Pat. No. 3,029,008 to Membrino discloses a composite
container for shipping items including a flexible inner liner that
is adhesively secured to an outer liner. The inner liner is
typically a continuous tube that is cut and inserted within the
outer liner, the tube being sealed using heat along a bottom
portion thereof. The inner liner is typically a flexible plastic
material, such as polyethylene, and the outer casing is typically
fiberboard, cardboard or corrugated carton sheet material.
[0004] U.S. Pat. No. 3,977,593 to Rotman discloses a carton capable
of resisting collapse when stored with other cartons or handled
carelessly. The carton is made from a unitary blank and has a
double front wall and a double bottom wall. The double front wall
is designed to resist compression under load and the double bottom
wall provides a rigid bottom that resists distortion under load,
and also assures that articles stored within the container will not
fall through openings frequently present in conventional folded
cartons.
[0005] U.S. Pat. No. 4,388,999 to Berry et al. discloses a
double-walled carton including a single blank comprising a series
of hinged-together panels that are folded spirally to form a
double-walled tube having spacers at all four corners of the carton
to maintain a space between the corresponding inner and outer
walls.
[0006] There are many problems associated with the prior art
described above. First, the prior art teaches using a single blank
for making both the inner and outer walls of a double-walled
container. Using a single blank, however may result in a container
having an outer liner that is less esthetically pleasing than
desired. The prior art also requires relatively complex blank
forming machine for making complex, unitary blanks foldable into
two box containers. Thus, there is a need for a double-walled
container whereby the outer layer may be made of a more
esthetically pleasing material than the material comprising the
inner box. In addition, there is a need to provide blanks for the
inner and outer boxes that may be made using less complex blank
forming machines. There is also a need for containers that can
change in reaction to the type of object being stored in the
container. Moreover, there is a need to minimize the amount of
material used and the cost associated with preparing such
materials.
[0007] Despite the advances in the prior art described above, there
remains a need for a double-walled container made of a composite
blank that is foldable to form a complete inner box surrounded by a
complete outer box.
SUMMARY OF THE INVENTION
[0008] The present invention is directed to forming a container
including an inner box surrounded and protected by an outer box.
The container is preferably used for packaging objects therein,
such as fragile goods, cosmetic fragrances or glass containers that
may be damaged during packaging and shipment. The present invention
also minimizes the amount of labor required to form prior art
double-walled containers, whereby the inner box is typically formed
separately from the outer box. Such prior art methods are extremely
labor intensive and cost inefficient.
[0009] In certain preferred embodiments of the present invention, a
container includes a first blank having fold lines and a series of
substantially rectangular panels that are hingedly connected to one
another at the fold lines of the first blank, and a second blank
including fold lines and a series of substantially rectangular
panels that are hingedly connected to one another at the fold lines
of the second blank. The first and second blanks are preferably
adhered to one another to form a composite blank that may be
spirally folded so as to form the container, wherein the first
blank forms an inner box of the container and the second blank
forms an outer box of the container that surrounds and protects the
inner box.
[0010] In certain preferred embodiments, the first and second
blanks are made of a substantially similar material having a
similar gauge thickness. In other embodiments, however, the first
blank preferably comprises a first material and the second blank
comprises a second material that is different in composition and/or
thickness than the first material. In some of these preferred
embodiments, the first blank is made of a first material that is
sturdier than the material comprising the second blank. Preferred
first blank materials include corrugated board, corrugated plastic
and styrofoam. Preferred corrugated board materials for the first
blank may be selected from the group consisting of B, C, E and F
flute corrugated board. The second blank forming the outer box of
the container is preferably made of paperboard, PVC, PET G, A PET,
R PET, polypropylene and assorted plastic materials.
[0011] The substantially rectangular panels of the first blank
preferably comprise in series a first sidewall, a rear wall, a
second sidewall adapted to oppose the first sidewall, and a front
wall adapted to oppose the rear wall. The first panel may also
include one or more tabs hingedly connected to upper or lower ends
of the first and second sidewalls or the front and rear walls of
the first blank. In one particular preferred embodiment, the first
and second sidewalls of the first blank include tabs hingedly
connected to upper ends thereof and a bottom tab hingedly connected
to a lower end of the front wall.
[0012] The substantially rectangular panels of the second blank
preferably include in series a front wall, a first sidewall, a rear
wall and a second sidewall. The second blank may also preferably
include an attachment flange hingedly connected to an outer edge of
the front wall of the second blank. The attachment flange is
preferably adapted to be adhered to an inner surface of the second
sidewall of the second blank when the container is assembled. After
the attachment flange and the second sidewall have been adhered
together, the two components preferably work in unison to provide a
second sidewall for the outer box of the container, as will be
described in more detail below.
[0013] In preferred embodiments, the second sidewall of the first
blank is adhered to the attachment flange of the second blank to
form a composite blank, whereby the front wall of the first blank
is juxtaposed with and overlies the front wall of the second blank.
The first blank desirably includes at least one upper end tab
hingedly connected to an upper end of one of the first and second
sidewalls for selectively closing an upper end of the inner box. In
particular preferred embodiments, the first blank includes a first
upper tab hingedly connected to the upper end of the first sidewall
and a second upper end tab hingedly connected to the upper end of
the second sidewall. When the container is assembled for receiving
an object, the first and second upper end tabs preferably oppose
one another. After an object has been placed in the container, the
tabs are forced toward one another for closing an upper end of the
inner box. The first blank may also preferably include one lower
end tab hingedly connected to a lower end of one of the front and
rear walls for selectively closing a lower end of the inner box.
The lower end tab is preferably forced into tits closed position
before the objected being packaged is placed in the inner box.
[0014] The second blank desirably includes at least one top closure
hingedly connected to an upper end thereof for selectively closing
an opening at an upper end of the container and at least one bottom
closure hingedly connected to the lower end thereof for selectively
closing an opening at a lower end of the container. The top and
bottom closures may include tongues having curved outer edges that
are designed to fit between the inner and outer boxes after the
container has been fully assembled.
[0015] Other preferred embodiments of the present invention
preferably include a container including a first blank made of a
first material, the first blank including fold lines and a series
of substantially rectangular panels hingedly connected to one
another at the fold lines of the first blank. The container also
desirably includes a second blank made of a second material that is
different than the first material, the second blank including fold
lines and a series of substantially rectangular panels hingedly
connected to one another at the fold lines of the second blank. The
first and second blanks are desirably adhered to one another to
form a composite blank that is spirally foldable to form the
container. After the composite blank has been spirally folded, the
first blank desirably forms an inner box of the container and the
second blank desirably forms an outer box of the container that
surrounds the inner box. The first blank desirably includes one or
more tabs hingedly connected to upper and/or lower ends thereof for
selectively covering the upper end and lower end openings of the
inner box. The second blank desirably includes closures hingedly
connected to upper and lower ends thereof for selectively closing
upper and lower end openings of the outer box. When the closures
are in their closed position, the closures of the second blank
preferably cover the tabs of the first blank.
[0016] These and other preferred embodiments of the present
invention will be described in more detail below.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0024] Referring to FIGS. 1-3, a double-walled container includes a
first blank 10, shown in FIG. 1, which is attached to a second
blank 70, shown in FIG. 2, to form a composite blank 130, shown in
FIG. 3. Referring to FIG. 1, first blank 10 includes a series of
fold lines 12, 14 and 16 that are preferably substantially parallel
to one another for dividing first blank 10 into a series of
substantially rectangular panels 18, 20, 22 and 24. The
substantially rectangular panels are hingedly connected to one
another at respective fold lines 12, 14 and 16. In the particular
preferred embodiment shown in FIG. 1, the rectangular panels
include a first sidewall 18 that is hingedly connected to a rear
wall 20 at fold line 12. Rear wall 20, in turn, is hingedly
connected with second sidewall 22 at fold line 14, and second
sidewall is hingedly connected with front wall 24 at fold line
16.
[0025] In preferred embodiments, first sidewall 18 includes upper
end 26 having an upper end tab 28 hingedly connected thereto along
fold line 30 and lower end 32 remote therefrom. An outer edge 34 of
first sidewall 18 includes an elongated projection 36. Rear wall 20
has an upper end 38 and a lower end 40 remote therefrom. Second
sidewall 22 has an upper end 42 hingedly connected to a second
upper end tab 44 at fold line 46 and lower end 48 remote therefrom.
Upper and lower cutouts 50A, 50B may be provided between rear wall
20 and second sidewall 22 in order to facilitate folding of first
blank 10 and assembly of a double-walled container, as will be
described in more detail below.
[0026] Front wall 24 of first blank 10 includes upper end 52 and
lower end 54 having lower end tab 56 hingedly connected thereto
along fold line 58. Fold line 58 may include a scored portion 60
whereby a cut line passes intermittently through front wall 24, as
well as an elongated cut line 62 that passes completely through
front wall 24 for an extended length. Although the present
invention is not limited by any particular theory of operation, it
is believed that providing the elongated cut line 62 facilitates
bending of lower end tab 56 during an assembly operation. Absence
of an elongated cut line would generally increase the amount of
force required to fold the lower end tab 56. An outer edge 64 of
front wall 24 includes an elongated slot 66 that preferably mates
with projection 36 of first sidewall 18 when first blank 10 is
folded to form a container.
[0027] Referring to FIG. 2, second blank 70 includes a series of
fold lines 72, 74, 76 and 78 that are preferably substantially
parallel to one another. The fold lines of second blank 70 divide
second blank into attachment flange 80, front wall 82, first
sidewall 84, rear wall 86 and second sidewall 88. As will be
described in more detail below, when the double-walled container is
fully assembled, the second sidewall 88 is preferably adhered to
flange 80 for securing second blank 70 in a tubular configuration.
Second sidewall 88 desirably includes an upper end 90 having flap
92 hingedly connected thereto along fold line 94 and lower end 96
having flap 98 hingedly connected thereto along fold line 100. Rear
wall 86 preferably includes upper end 102 and lower end 104
including closure 106 hingedly connected to lower end 104 along
fold line 108.
[0028] Second blank 70 also includes first sidewall 84 having upper
end 110 including upper end flap 112 hingedly connected thereto
along fold line 114 and lower end 116 including lower end flap 118
hingedly connected thereto along fold line 120. Front wall 82
desirably includes upper end 122 having closure 124 hingedly
connected thereto along fold line 126 and lower end 128 remote
therefrom.
[0029] Attachment flange 80 is hingedly connected to front wall 82
along fold line 72, which in turn, is hingedly connected to first
sidewall 84 along fold line 74, which in turn, is hingedly
connected to rear wall 86 along fold line 76, which in turn, is
hingedly connected to second sidewall 88 along fold line 78.
[0030] In certain preferred embodiments, the first and second
blanks may comprise similar materials. In other preferred
embodiments, however, the first blank 10 may be made of a material
that is different than the material comprising the second blank 70.
In particular preferred embodiments, first blank 10 comprises a
material that is thicker than the material of second blank 70. In
these embodiments, the first blank may comprise B, C, E and/or F
flute corrugated board, PVC corrugated plastic or styrofoam. The
second blank 70 may be made of paperboard having a gauge different
than that of the first blank. The second blank may also be made of
PVC, PET G, A PET or R PET. The two blanks 10, 70 are preferably
aligned and glued together to form the composite blank 130 (FIG. 3)
using a machine such as that disclosed in U.S. Pat. No. 4,549,878,
the disclosure of which is hereby incorporated by reference herein.
The machine that assembles the two blanks 10, 70 may also fold the
composite blank and apply glue where necessary to form a flattened
container including the first blank 10 comprising an inner box and
the second blank 70 comprising the outer box. The flat container
may then be shipped to a packaging plant where the container is
expanded into a shape suitable for having an object packaged
therein.
[0031] Referring to FIGS. 1-3, first blank 10 and second blank 70
are preferably adhered to one another, such as by using adhesive
(not shown), to form a composite blank 130 that may be assembled to
form a container. In one particular embodiment, an adhesive is
preferably provided between attachment flange 80 and second
sidewall 22 of first blank 10 for adhering flange 80 and second
sidewall 22 together which, in turn, adheres first and second
blanks 10, 70 together. During this assembly step, the fold lines
of the respective first and second blanks 10, 70 as preferably
positioned in substantially parallel alignment with one another.
After attachment flange 80 and second sidewall 22 have been
attached together, the front wall 24 of first blank 10 preferably
overlies the front wall 82 of second blank 70.
[0032] Referring to FIGS. 3 and 4, first blank 10 is then folded
along fold line 14 so that rear wall 20 and first sidewall 18 of
first blank 10 overlie front wall 24 of first blank 10 and front
wall 82 of second blank 70.
[0033] Referring to FIGS. 4A and 4B, the second blank is then
preferably folded along fold line 74 so that the front wall 82 of
second blank 70 overlies rear wall 86 of second blank 70.
[0034] Referring to FIGS. 4B and 4C, an adhesive material, such as
glue, is preferably placed atop an outer face of attachment flange
80 or second sidewall 88 of second blank 70 is folded along fold
line 78 for adhering second sidewall 88 to attachment flange 80. In
the particular embodiment shown in FIG. 4C, the assembly is
preferably maintained substantially flat and includes the first
blank forming an inner box which is surrounded by second blank 70
forming an outer box of a container. The joined together second
sidewall 88 and attachment flange 80 of second blank 70 are
hereinafter referred to as the second sidewall of outer box.
[0035] The container shown in FIGS. 4C and 5A is preferably shipped
in a flat condition to a packaging plant wherein objects, such as
bottles, may be packed into the containers. Referring to FIGS.
4A-5D, the container is then expanded into a three-dimensional
configuration suitable for receiving an object packed therein. In
FIG. 5A, the container is substantially flat, with front wall 82
and second sidewall 88 of second blank 70 overlying rear wall 86
and first side 84 of second blank 70. Referring to FIG. 5B, first
blank 10 forming an inner box and second blank 70 forming an outer
box of the container are subjected to external forces so that the
respective front walls 24 and 82 of the first and second blanks
move away from the opposing rear walls 20 and 86 of the first and
second blanks. Simultaneously, first and second sidewalls of the
inner and outer boxes swing about pivot points at lower ends
thereof relative to rear walls 20, 86. Referring to FIG. 5C, the
first and second sidewalls continue to move in a direction
indicated by the arrows until the container is arranged in the
expanded configuration shown in FIG. 5D. As shown in FIG. 5D, first
blank 10 forms an inner box 140 that is surrounded by second blank
70 that forms an outer box 150 surrounding inner box 140. The
container includes adhesive 160 securing second sidewall 88 to
flange 80.
[0036] Referring to FIG. 4D, after the container has been opened to
the expanded configuration shown in FIG. 5D, an object may be
placed inside the container. Although the present invention is not
limited by any particular theory of operation, it is believed that
providing a container including an inner box surrounded by an outer
box will better protect an object stored within the container.
[0037] In order to place an object within the container of FIG. 4D,
the tab enclosures at the upper and lower ends of the container may
be closed either manually or automatically using a packing machine.
In one preferred embodiment, a packing machine selectively engages
the tab enclosures at the upper and lower ends of the container in
a systematic fashion in order to secure an object therein. In one
preferred embodiment, a force is applied to lower end tab 56 for
folding lower end tab along its fold line (not shown) so as to
partially cover an opening at a lower end of the container. The
opposing lower end flaps 98, 118 are then forced towards one
another so as to cover lower end tab 56 and further enclose the
lower end of the container. The lower end closure 106 is then
folded so that tongue 107 is preferably secured between the front
walls of the first and second blanks (not shown). Once the lower
end closure 106 has been secured in place so as to effectively
close the lower end of the container, an object, such as a bottle,
may be placed through an opening at the upper end of the container.
The lower end tab 56 and opposing lower end flaps 98, 118
preferably abut against and/or support a lower end of the packaged
object. The opening at the upper end of the container is then
preferably closed by first forcing the opposing upper end flaps 92,
112 toward one another so as to cover the upper end opening.
Although not shown in FIG. 4D, preferred embodiments of the present
invention may also include opposing upper end tabs 28, 44 hingedly
connected to first blank 10, the upper end tabs 28, 44 being
movable toward one another to selectively cover the opening at the
upper end of the container. The upper end closure 124 is then
folded whereby tongue 125 is secured in place between the rear
walls 20, 86 of the respective first and second blanks.
[0038] Although the invention herein has been described with
reference to particular embodiments, it is to be understood that
these embodiments are merely illustrative of the principles and
applications of the present invention. For example, the number,
size and shape of the panels may be readily modified depending upon
the size and shape of an object being packed in the container.
Moreover, the number of tabs and closures and the location of the
tabs and closures may be modified. The materials used to form the
