Description
BACKGROUND OF THE INVENTION
This invention relates to packaging, and more particularly to
dual-compartment packages that are readily assembled for displaying
one stored item and concealing another, associated stored item.
For some stored items, their packaging should fulfill a multiple
role. On the one hand, some measure of storage protection should be
provided. On the other hand, the package should be able to display
the stored item to advantage. In addition, there are some items
that are desirably stored with other closely associated items that
do not require being displayed, or in some cases, should not be
displayed at all because of their negative esthetic effect.
For example, batteries that must supply large amounts of current,
either for starting or for other operations, typically employ a wet
electrolyte or an ionic fluid such as aqueous sulphuric acid
solution of appropriate concentration. Such batteries are desirably
shipped in a dry-charged state, without their electrolyte, to
reduce the chance of spillage, evaporation or other loss of
electrolyte during shipment and to prevent the "shelf-life" effect
by which a fully-charged battery with electrolyte tends to lose its
charge in time.
When a battery is shipped in its dry-charged state, it can be
readied for use immediately by having its cells filled with the
proper electrolyte. Since the electrolyte is a poisonous and
corrosive liquid that can cause severe burns, it is preferable for
each battery to be accompanied by a separate pack which contains
the correct amount and strength of electrolyte.
When a dry-charged battery is shipped to a vendor, it is often
placed on display, so that it will attract the attention of
potential users and can be easily placed in service. The
electrolyte pack that accompanies the battery does not have any
particular merchandising appeal, and as such, tend to be stored
away from the batteries on display, generally in some location
where there is little customer access. Unfortunately, the
separation of a dry-charged battery from its electrolyte pack means
that there will be delay when the time comes for placing the
battery in service. There are occasions when the correct
electrolyte pack cannot be found, or no pack at all can be
found.
Accordingly, it is an object of the invention to facilitate the
packaging of associated items. A related object is to facilitate
the display packaging of one such item, together with the
non-display packaging of an associated item. Another related object
is to provide for the display packaging of a dry-charged battery,
together with the non-display packaging of its associated
electrolyte pack.
In order for a packaged item to be displayed, its storage
compartment must be at least partially open. The open portion of
the package has less strength than the part that is closed. When
the open, display compartment is to contain a dry-charged battery,
which is comparatively bulky and heavy, the strength of the package
is important.
Consequently, it is a further object of the invention to achieve a
durable display compartment for a storage package. A related object
is to achieve such a compartment for a dry-charged battery.
In addition to being durable, the display compartment of a storage
package should provide a desirable esthetic effect. The sales
appeal of a meritorious product will be enhanced if the display
compartment sets forth the stored item to advantage. Hence, a
further object of the invention is to achieve a storage package
which provides a desirable display. A related object is to achieve
a "shadow box" affect.
In the case of a storage package with both display and closed
storage compartments, access to the former is generally easy and
direct. But access to the closed compartment can be difficult,
cumbersome and time consuming. It is the further object of the
invention to achieve easy access to the storage compartment.
Another object of the invention is to provide a reusable storage
package with both an open display compartment and a closed storage
compartment. Still another object is to achieve a storage package
that can be readily collapsed to a flat state for easy and
efficient handling until the package is to be assembled for use in
providing a display compartment and a closed storage
compartment.
SUMMARY OF THE INVENTION
In accomplishing the foregoing and related objects, the invention
provides a package with a set of panels that have both end and side
edges. At least some of the panels are hinged together at their
side edges. A set of extensions of the panels is used to form a
closed end of the package, and another set of extensions of the
panels form a partially open, opposed end of the package. In
addition, one of the panels has an extension that is used for
dividing the package into an open, display compartment and a
closed, storage compartment.
In accordance with one aspect of the invention, the separator
extension that is used to divide the package into display and
closed compartments is hinged to the top panel of the package. In
accordance with another aspect of the invention, the separator
extension of the top panel includes a tongue for establishing a
removable connection by engagement with an aperture in a base panel
of the package.
In accordance with still another aspect of the invention, some of
the panels have extensions which are interiorally foldable for the
reinforcement of the partially open end of the package. The
reinforcement extensions are desirably provided on the side panels
of the package.
In accordance with a further aspect of the invention, the
additional extensions on the side panels of the package are
diagonally foldable against their associated panels to enhance the
reinforcement of the partially open end of the package. The
reinforcement is particularly enhanced when the packaging material
is of corrugated cardboard so that the diagonal folding causes the
corrugations of the extensions, when folded against the side
panels, to be perpendicular to the corrugations of the side
panels.
In accordance with yet another aspect of the invention, one of the
extensions of the panels that is used to form the partially open
end of the package includes a front panel that is hinged to a base
panel which further includes a reinforcement extension that is
hinged to the front panel.
In accordance with still a further aspect of the invention, the
package includes a base panel, a left-side panel, a top panel, and
a right-side panel; and the extensions include respective end flaps
that are hinged to each side panel, to the top panel, and to the
base panel. The end flaps are inwardly foldable with the flaps of
the side panels being folded over the flap of the top panel and the
flap of the base panel having a tongue which is pushed against and
engages a recess in the flap of the top panel. This configuration
of the end flaps facilitates the formation of the closed end of the
package.

DETAILED DESCRIPTION
Turning to the drawings, FIG. 1 shows a dual-compartment package 10
in accordance with the invention with an open display compartment D
and a closed, storage compartment S. The display compartment D
illustratively contains a dry-charged battery 70, while the storage
compartment S contains a companion package (not visible in FIG. 1)
of electrolyte for the battery 70.
In general, the dual-compartment package 10 is useful where it is
desired to display one item and simultaneously have it accompanied
by an associated, non-display item.
Thus, in the case of the battery 70, the package 10 provides an
esthetically pleasing display arrangement. At the same time, it
provides storage for an associated, although esthetically less
pleasing electrolyte package, and assures that the battery 10 will
always be accompanied by the proper electrolyte. This is by
contrast with the ordinary display situation for dry-charge
batteries where the displayed battery becomes separated from its
associated electrolyte, and there is confusion, and possible error
when the battery is to be filled with electrolyte and placed in
service.
Constituting the dual-compartment package 10 of FIG. 1 are a
right-side panel 21 (as viewed from the front or display end of the
package), a top panel 31, a left-side panel 41 (only partially
visible in FIG. 1), and a front panel 51.
The display compartment D is formed by the portion of the container
10 demarked by the front panel 51, the diagonal portions of the
side panels 21 and 41, and a separator flap 32. The latter is
hinged to the top panel 31 and has characteristics described in
detail below. In addition, the package 10 has a base panel which is
not visible in FIG. 1.
The storage compartment S is formed by the top panel 31, the
separator flap 32, and the rear portions of the side panels 21 and
41. Completing the closed storage compartment are the base panels
and exteriors of the top, side and base panels, which form the
closed end of the package and are not visible in FIG. 1.
In the case of the display compartment D, hinged extensions of the
side panels 21 and 41, and the front panel 51, are folded towards
the interior of the compartment in a manner more particularly
described below. These folded extensions reinforce the walls of the
display compartment D which is otherwise weakened by being open and
cut away. The extentions also help provide a "shadow box" display
effect because the displayed item 70 is held inwardly, i.e., is set
back, from the outer panels 21, 41 and 51.
The setback of the displayed battery 70 is shown in greater detail
in the fragmentary cross-sectional FIG. 1A. The front panel 51 has
an extension 52 that is inwardly folded over an extension 23 of the
right-side panel 21 (FIG. 1). The fold of the extension 52 alone
produces a desired setback of the battery 70 from the front panel
51. This setback is enhanced by a projection 71 of the battery 71
near the base panel 61 of the display compartment. Such projections
are typically molded in batteries in order to assist in providing
proper seating in the vehicles with which they are used. These
molded projections are used to advantage in the display compartment
D by enhancing the "shadow box" effect that is otherwise provided
by the folded extensions of the front and side panels.
As noted above, the dual-compartment package 10 of FIG. 1 provides
display storage of the battery 70 and closed storage of an
associated electrolyte package until the battery is to be put into
service. The package 10 also serves as a shipping container for the
battery and its associated electrolyte package. Since there is a
possibility that the package 10 may become upturned in handling,
permitting battery 70 to fall from its display compartment,
notwithstanding that battery tends to be grippingly held by the
folded extensions of the panels 21, 41 and 51, further packaging
techniques may be employed. For example, the entire package 10,
with its stored items, may be encased in a cellophane skin of the
pre-shrunk type. Alternatively, the front, top, back and bottom
portions of the package may be enclosed by a shipping sleeve (not
shown). Such a sleeve is illustratively formed by four hinged
panels of cardboard which are joined as an open-sided
parallelopiped into which the package 10 is inserted.
When the contents of the package 10 of FIG. 1 are to be used, the
battery 70 is removed and the separator flap 32 is lifted upwardly
in the direction indicated by the clockwise arrow A as shown in
FIG. 2. There is then direct access to the stored package 80. When
the display compartment D contains a battery 70, the stored package
80 contains electrolyte (battery fluid) of sulphuric acid. In that
event the container 80 is illustratively a cardboard package with a
plastic liner that has a clamped dispensing hose.
Since the top panel 31 of the package 10 is just above the filling
ports of the battery 70 (FIG. 1), it provides a convenient surface
for filling the battery from the electrolyte pack 80. For that
purpose the separator flap 32 of FIG. 2 can be moved to its closed
position and the battery 70 reinserted into the display
compartment. The electrolyte pack 80 is placed on the top panel 31,
the vent caps of the battery 70 are removed, and the cells of the
battery are filled from the dispensing hose of the electrolyte pack
80.
When the separator flap 32 of FIG. 2 is in its closed position (see
FIG. 6), a tongue which may be the shown split tongue 32t of the
separator flap 32 is inserted into a slot 61a in the base 61 of the
package 10. The two portions of the split tongue 32t are separated
by an aperture 32a that allows the user to pull upwardly on the
separator flap 32 when access to the internally stored container 80
is desired. It will be understood that the access aperture 32a may
take other forms, being, for example, a circular port in a unitary
form of the tongue 32t.
Also indicated in FIG. 2 is the reinforcement action of the
extension 42 of the left side panel 41. The material of the package
10 is desirably of corrugated cardboard so that when the extension
42 is folded diagonally against the side panel 41, with a tongue
42t of the extension 42 inserted into an aperture 61d in the base
panel 61, the corrugations of the panel 41 are at right angles to
the corrugations of the extension 42.
When the dual-compartment container 10 of FIGS. 1 and 2 is in its
completely disassembled state, it has the configuration shown in
FIG. 3. The disassembled container 10 is realized from a single
sheet of stock that is advantageously of the corrugated cardboard
variety. It is oriented in FIG. 3 such that the constituents which
form the back of the package 10 in FIG. 1 are at the bottom of the
sheet, while the constituents which form the front of the package
are at the top of the sheet. Accordingly, the configuration of FIG.
3 is realized by rotating the package of FIGS. 1 and 2 through
approximately 150.degree. clockwise and separating its right side
end 21 from the base panel 61.
The particular manner of separation will become apparent from FIG.
6 which shows an extension 62 of the base 61 adjoining the inside
wall of the panel 21. When the flaps of the panels 21, 31, 41, 51
and 61 are extended, the result is the planar, multi-panel
configuration of FIG. 3.
Each of the panels 21, 31, 41, 51 and 61 has end and side edges. At
least some of the panels are hinged together at their side edges;
thus one side panel 21 is hinged to the top panel 31 along a score
line 21x; the top panel 31 is, in turn hinged along a score line
41x to the other side panel 41. The latter is hinged to the base
panel 61 along a score line 61x, and the base panel 61 is hinged to
the front panels 51 along a score line 51x.
The side panels 21 and 41, together with the top panel 31 and the
base panel 61, have a set of extensions 24, 44, 34 and 64 which can
be folded along respective score lines 24x, 44x, 34x and 64x to
form a closed end of the package 10 of FIG. 1. The side panels 21
and 41, have another set of extensions 23 and 43. These extensions
together with an extension 52 of the front panel 51, which are
foldable along respective score lines 23x, 43x and 52x form the
partially open end of the package 10.
An extension 32 of the top panel 31, foldable, along score line
32x, is used to divide the package into the open, display
compartment D and the closed, storage compartment S.
In addition to the end flaps 23 and 24 in the right side panel 21,
and the end flaps 43 and 44 on the left-side panel 41, the side
panels 21 and 41 have additional extensions 22 and 42 which are
hinged to their respective panels along score lines 22x and 42x.
These additional extensions 22x and 42x have tongues 22t and 42t
and are diagonally foldable over the panels 21 and 41 so that the
tongues 22t and 42t engage apertures 61c and 61d in the base panel
61 when the package 10 is being assembled.
In the case of the top panel 31, the end flap extension 34 has two
apertures 34a and 34b. The smaller aperture 34a is of triangular
configuration and permits easy grasp of the end flap 34. The larger
aperture 34b is at the end of the flap 34 and is a rectangular
recess that receives a tongue portion 64t of an extension 64 of the
base panel 61 when the package 10 of FIG. 1 is being assembled.
Besides having an end flap 64 with a tongue 64t, the base panel 61
has a side flap 62 to which it is hinged along a score line 62x.
This side flap 62 forms a hinge for connecting the base 61 to the
otherwise unconnected side panel 21. The base 61 also has an
aperture 61a for receiving the tongue 32t of the separator
extension 32 of the top panel 31 and a parallel aperture 61b for
the tongue 52t of an extension 52 of the front panel 51.
To form a collapsed package for storage from the unfolded package
configuration of FIG. 3, the base panel 61, and associated
elements, and the right-side panel 21, and associated elements, are
manipulated as indicated by FIG. 4.
The base panel 61, and its associated elements shown in the phantom
position 61' in FIG. 4, is folded in a clockwise direction
indicated by the arrow X over the left-side panel 41 and its
extensions. As a result, the side extension 62 of the base panel 61
overlies the top panel 31. The right-side panel 21 and its
associated elements shown in phantom position 21' in FIG. 4, is
folded in a counterclockwise direction indicated by the arrow Y, so
that the right-side panel 21 overlies the side flap 62 and the
remainder of the top panel.
The flap 62 is then secured to the contacting surface of the side
panel 51. The result is a collapsed dual-compartment storage
package which can be readily opened and assembled to realize the
dual-compartment package 10 of FIG. 1.
In manipulating the collapsed package of FIG. 4 for the open
display and closed storage of associated components, the package is
desirably turned over, since the base 61 has an upper position in
FIG. 4. Next, the right-side panel 21 is grasped with the left
hand, and the left-side panel 41 with the right hand and rotating
the panels that are grasped in a clockwise direction. The result is
to open the package to the rectangular cross-sectional form shown
in FIG. 5, which is a back view of the package of FIG. 1 in the
course of assembly.
The top end flap extension 34 is folded along the edge 34x at an
angle of 90.degree. with the top panel. The base end flap extension
64 is in planar alignment with the base, before being folded
upwardly along the score line 64x. The respective side flap
extensions 22 and 44 have been partially folded inwardly at edges
24x and 44x.
To close the back of the package in FIG. 5, the side panel
extensions 24 and 34 are folded against the top extension 34 until
they are aligned with the score mark 64x between the base extension
64 and the base panel.
Assembly of the back of the package is then completed by folding
the extension 64 of the base upwardly about the score-line 64x
until the tongue 64t contacts the upper extension 34 to move
inwardly until the tongue 64t clears the rectangular opening 34b,
at which point the top extension 34 springs back so that rear of
the package has the configuration indicated in FIG. 5A. The
triangular aperture 34a provides a convenient grasping point for
pulling the back of the package into the desired position, or
disassembling the back, if that is desired.
When the partially assembled package of FIG. 5 is viewed from the
front, it has the configuration shown in FIG. 6 during the course
of final assembly.
The package 10 of FIG. 6 has the tongue 32t of its separator flap
in engagement with the corresponding slot 61a of the base panel.
The assembly of the package is otherwise complete, except for the
right-side panel 21 and the front panel 51.
To complete the assembly, the extension 22 of the right-side panel
21 is diagonally folded along the score line 22x, over the side
flap 62 of the base panel, with the tongue 22t in engagement with
the slot 61c of the base panel. The final assembly of the front
panel 51 is achieved by positioning the end flap 23 of the
right-side panel 21 in alignment with the score line 51x; then
folding the front panel 51 upwardly; followed by folding the
extension 52 over the end flaps 23 and 43 until the tongue 52t
engages the slot 61b of the base panel.
While the various aspects of the invention have been set forth by
the drawings and the specification, it is to be understood that the
foregoing detailed description is for illustration only and that
various changes in parts, as well as the substitution of equivalent
constituents for those shown and described may be made without
departing from the spirit and scope of the invention as set forth
in the appended claims.
