BACKGROUND OF THE INVENTION
This invention relates to packaging for flat articles such computer
software discs, and in particular to a combination display/storage package
which includes a hinge having a guideway for bearing indicia identifying
the contents of the package, and to a file for the display package.
Display and storage packages for articles come in a myriad of shapes and
sizes, depending on the use of the package. A typical package is made at
least partially of plastic and packages of the nature of the invention are
usually entirely plastic and formed by a thermo-forming process. Such a
package includes a top and a bottom which may be engaged as appropriate,
and a living hinge between the top and the bottom along one edge of the
package.
When the package is thermo-formed, at least one edge of the top and the
bottom includes a back draft so that the top and the bottom may be
fastened together when closed. While the package is thus securely held
together, it becomes difficult to open unless provided with a handle,
knob, recess, or other means to assist opening of the package. In the
typical thermo-formed package, the means of opening assistance is formed
in the middle of one edge of the package but, since the package is
flexible, force at the opening means tends to deform the package and
actually increase the opening force necessary to open the package.
In prior art packages, an identifying label is often applied to the package
or a visible card or other means of identification is slipped inside the
package when the product is inserted therein. While such may be adequate
in most instances, for flat packages which are stacked one above another,
it becomes almost impossible to identify the contents of the package
without removing the package from the stack and viewing either the label
or the internal card.
SUMMARY OF THE INVENTION
The invention is an improved display/storage package for flat articles
which includes, as primary components, a bottom portion and a top portion
complementary to the bottom portion, the top and bottom portions, when
engaged to constitute a closed package, forming an internal compartment
for one or more flat articles. Means is provided for securing the top
portion to the bottom portion to form the closed package, and means is
provided for assisting opening of the package when it is closed. A hinge
connects the top and bottom portions along one edge thereof and includes a
longitudinal channel forming a guideway for bearing indicia identifying
the contents of the package.
In one embodiment of the invention, a rest for articles is formed within
the package. The rest comprises a raised ledge in each corner of the
bottom portion which supports the four corners of a flat article contained
within the package. In either embodiment of the invention, the top portion
includes a central depression formed to bear against an article within the
package. In the first embodiment of the invention, the depression and the
ledges are formed to cooperate to suspend an article within the package.
In the second embodiment of the invention, the depression simply bears
against the top-most article contained within the package.
In order to secure the top and bottom portions together when closed,
complementary interlocking latch elements are formed in the top portion
and the bottom portion. Since the package is plastic which is
thermoformed, the latching elements comprise a back-draft in the forming
process which interlock when the package is closed.
In either embodiment of the invention, a peripheral flange is formed in the
top and bottom portions. The flanges contact one another when the package
is closed. In order to assist opening of the package, in one embodiment of
the invention a gap is provided between the flanges at the corners of the
package opposite the hinge. In the other embodiment of the invention, one
of the flanges overlaps the other at the same corners so that the single
extended flange can be engaged for opening.
A storage file is provided for one or more of the display/storage packages.
The storage file comprises a housing and a liner for the housing, with the
liner including at least one pair of opposed grooves shaped to guide and
retain the package within the file. The liner is composed of four
segments, a top, two sides and a bottom, with the segments being formed in
a longitudinal strip and with adjacent segments being joined with a living
hinge. Each segment includes a snap element adjacent its living hinge with
the snap element on one side of the living hinge being shaped to engage a
corresponding snap element on the other side of the living hinge so that
when the liner is folded about its living hinges to its quadrangular form
for insertion within the housing, the snap elements interlock to retain
the shape of the liner and also strengthen the housing.

DESCRIPTION OF EXAMPLES EMBODYING BEST MODE OF THE INVENTION
One embodiment of a display/storage package according to the invention is
shown generally at 10 in FIGS. 1 through 3. The package 10 includes a
bottom portion 12, a top portion 14, and a hinge 16 connecting the bottom
portion 12 to the top portion 14. Each of the portions 12 and 14 includes
a respective peripheral flange 18 and 20 which, as shown in FIGS. 1 and 3,
contact one another when the package 10 is closed.
The bottom portion 12 includes a rest for articles located within the
package 10. As best shown in FIG. 2, the rest comprises a raised ledge 22
in each corner of the quadrangular bottom portion 12. The package 10 and
its bottom portion 12 are shaped to accommodate a flat article, such as a
computer software disc 24 with the disc 24 resting on the corner ledges 22
as shown in the drawings.
The top portion 14 is formed complementary to the bottom portion 12 so that
the two portions, when closed, form an internal compartment for the
computer disc 24. The top portion 14 is further provided with a circular
depression 26 centrally in the top portion 14 in general alignment with
the center of the disc 24 when lodged within the display package 10. As
best shown in FIG. 3, the circular depression 26 includes a circular bead
28 which engages the disc 24 at the periphery of a center hole 30 of the
disc 24. Thus, as shown in FIG. 3, when the package 10 is closed, the bead
28 of the circular depression 26 bears against the top of the disc 24
while the corner ledges 22 bear against the bottom of the disc 24 to
firmly suspend the disc 24 midway between the bottom portion 12 and top
portion 14 of the package 10.
The hinge 16 is preferrably a living hinge which connects the bottom
portion to the top portion 14. As best shown is FIG. 3, the hinge 16 is
configured with a longitudinal channel 32 forming a guideway for a strip
34 of paper, plastic or other material shaped to be inserted within the
channel 32. The strip 34 carries suitable identification for the disc 24
contained in the package 10 and, as shown, is situated so that information
on the strip 34 can readily be seen when the display packages 10 are
stacked one upon the other.
As shown in FIGS. 1 and 3, the flanges 18 and 20 of the bottom portion 12
and top portion 14 separate the hinge 16 from the remainder of the package
10, thus forming the hinge 16 as a handle which is particularly useful in
connection with the file described below in connection with FIGS. 7
through 10. The hinge 16 therefore performs at least three functions, a
hinging function, a display function for the strip 34, and a handle
function for manipulating the closed package 10.
The flange 18 is extended at 36, forming corner recesses 38. Similarly, the
flange 20 is extended at 40, forming corner recesses 42. Preferrably, the
recesses 42 and 38 are configured such that when the package 10 is closed,
the flange 20 adjacent the extension 40 overlaps the flange 18 adjacent
the extension 36 so that the corners 42 of the top portion 14 can be
engaged to open the package 10.
A second embodiment of the invention is shown in FIGS. 4 through 6. In this
embodiment, the display/storage package, generally designated 50, includes
a bottom portion 52, a top portion 54 and a hinge 56 interconnecting the
bottom and top portions 52 and 54. The hinge 56 is identical to the hinge
16 of the first embodiment of the invention and, in a similar fashion, may
carry a strip 58 having suitable identification for a disc 60 to be
contained within the display package 50.
Like the embodiment of FIG. 1, the bottom portion 52 includes a peripheral
flange 62. Likewise, the top portion 54 includes a peripheral flange 64.
The flanges 62 and 64 contact one another when the package 50 is closed,
as best shown in FIG. 5.
Similar to the embodiment of FIGS. 1 through 3, the top portion 54 includes
a circular depression 66 having a circular bead 68. Unlike the package 10
of the first embodiment of the invention, the package 50 does not include
corner ledges such as the ledges 22, and therefore more than one disc 60
can, depending on the depth of the depression 66 and bead 68, be
accommodated within the package 50. The bead 68 is, similar to the first
embodiment of the invention, intended to engage the periphery of the
central hole of the top-most disc 60 within the package 50.
A dimple 70 is formed in the flange 62 at each corner of the bottom portion
opposite the hinge 56. Similarly, a dimple 72 is formed in the flange 64
at each corner of the top portion 54 opposite the hinge 56. When the
package 50 is closed, and as best shown in FIG. 6, the dimples 70 and 72
form a gap 74 at the corners of the package 50 which permit one to easily
insert a finger tip between the dimples 70 and 72 to open the package 50.
In either embodiment of the invention, the top portion 14 or 54 fits over
the respective bottom portion 12 or 52 when the respective package 10 or
50 is closed. The top and bottom portions are snapped together in order to
lock them in the closed orientation. While the particular means of
interfitting the top and bottom portions for secure closure forms no part
of the present invention, a particular means is shown in FIG. 5. As seen,
the top 54 has a back drafted mostly vertical leg 76 to which the flange
64 is attached. Similarly, the bottom portion 52 has a back drafted mostly
vertical leg 78 to which the flange 62 is attached. The back drafts of the
legs 76 and 78 cause the top portion 54 to snap over the bottom portion 52
when closed, in a conventional fashion. The back draft of the legs 76 and
78 may continue about the entire peripheries of the top portion 54 and
bottom portion 52, or any part thereof, as desired.
One form of a file, generally designated at 80, for the display/storage
packages 10 or 50 is shown in FIGS. 7 through 10. Although the
display/storage package 50 is shown in association with the various
elements of the file 80, it is evident that the display/storage package 10
or any similar, flat package, could be employed in conjunction with the
file 80, as set forth in greater detail below.
The file 80 is composed of two basic components, a housing 82 and a liner
84 for the housing 82. As shown, the housing 82 is a simple, box-like
structure having a top 86, opposed side walls 88 and a bottom 90. Although
it is preferred that the housing 82 also include a rear wall 92, such is
not essential and may be omitted if desired. The housing 82 is preferably
formed from plastic in a conventional fashion, such as by thermo-forming.
It may, as well, be made of other materials such as cardboard which is
formed into the cubical shape shown.
The liner 84 is, similar to the housing 82, formed having a top 94, opposed
sidewalls 96, and a bottom 98. The dimensioning of the liner 84 is such
that there is a close fit between the liner 84 when assembled and inserted
within the housing 82.
The side walls 96 are provided with a series of pairs of opposed grooves
100 shaped to guide and retain the package 50 within the file 80 when
assembled. The dimensioning of the grooves 100 is dependent on the width
of the package 50 and its flanges 62 and 64 (FIGS. 4 through 6) on the
opposite sides thereof. It is evident that the shape of the grooves 100
can be varied to accommodate the particular package housed therein.
As shown in FIG. 8, the liner 84 may be thermo-formed from a single strip
of material with adjacent elements being interconnected by a living hinge
102. In order to maintain the configured shape of the liner 84 prior to
insertion within the housing 82, each of the top 94, side walls 96 and
bottom 98 is provided with a snap element adjacent the living hinges 102
so that when the liner 84 is folded into the quadrangular configuration
shown in FIG. 7, that configuration is maintained. As shown best in FIG.
10, the snap elements comprise a male snap element 104 which engages a
corresponding female snap element 106. The elements 104 and 106 are
configured such that there is a close, tightly-retaining fit between the
two so that the liner 84 is at least temporarily held in the assembled
configuration (FIG. 7) before insertion within the housing 82. A pair of
respective snap elements 104 and 106 can be located in each edge of the
top 94, side walls 96 and bottom 98, as shown in FIG. 7.
When the file 80 is assembled, several of the display/storage packages 50
can be accommodated therein in the opposed grooves 100, and in the
embodiment illustrated, five of the display/storage packages 50 can be so
accommodated. Because of the configuration of the hinge 56, the hinge 56
serves as a handle to permit the user to readily grasp the package and
insert the display/storage package 50 into or withdraw it from the file
80.
Various changes can be made to the invention without departing from the
spirit thereof or scope of the following claims.
