FOOD CONTAINER CONSTRUCTION
Abstract
A container construction comprising front, back, side and bottom
walls and an open top. The respective walls are separated from each
other by means of fold lines, and additional fold lines extend
across the bottom and side walls whereby the construction can be
folded into a flat configuration. A still further fold line extends
across the bottom wall between the front and back walls. When the
bottom is pushed upwardly along this fold line, the container will
lock in the open position. A caricature is displayed on the outer
surface of the front wall and on the inner surface of the back
wall. When the side walls are cut away after use of the container,
the caricature provides a toy which will change in appearance when
the front and back walls are moved relative to each other.

Description
This invention relates to a container construction useful for
holding food products. The invention is particularly directed to a
container of the disposable type.
Because of the wide popularity of drive-in eating establishments,
there has been an increased need for disposable food containers.
Such containers must be relatively inexpensive and, therefore, they
must be capable of being economically manufactured. Complex cutting
or scoring techniques, or containers which require special
materials or multiple parts, are totally unsuitable for volume
operations of the type referred to.
It is also desirable to provide containers which can be easily
marked to identify the establishment using the container. Since
heavy paper or cardboard material is relatively inexpensive and can
be readily printed, such materials are ideally suited for the
production of large numbers of containers. These materials are also
easily disposed of after use.
Containers which are compact and which can, therefore, be stored in
a minimum of space are preferred. Containers which are held flat
during storage and which can then be opened up for use are
particularly suitable for holding food products.
It is a general object of this invention to provide an improved
design for a container construction which is particularly suitable
for use in drive-in type eating establishments or in similar
establishments where large volumes of disposable containers are
employed.
It is a further object of this invention to provide a container
construction which can be economically manufactured from heavy
paper or cardboard, which is produced from an easily assembled,
one-piece blank, which can be folded flat for storage in compact
fashion, and which can be easily snapped into an open and locked
position for use.
It is a still further object of this invention to provide a
container construction which is readily adapted for the display of
a caricature as well as other printed material whereby the
container can be used as an amusement device after use as a food
container.
These and other objects of this invention will appear hereinafter
and for purposes of illustration, but not of limitation, specific
embodiments of the invention are shown in the accompanying drawings
in which:
FIG. 1 is a front perspective view, partly cut away, illustrating a
container construction of this invention;
FIG. 2 is a rear perspective view of the container construction
shown in FIG. 1;
FIG. 3 is a front plan view of the container construction having a
caricature printed thereon;
FIG. 4 is a rear plan view of the container construction;
FIG. 5 is a plan view of a blank employed in producing the
container construction;
FIG. 6 is a plan view of the caricature after it has been cut away
from the remainder of the container; and,
FIG. 7 is a side view of the caricature shown in FIG. 6.
The container construction of this invention comprises front and
back walls, side walls, a bottom wall, and an open top. The bottom
wall is separated from the front and back walls by means of a fold
line, and additional fold lines extend between the side walls and
the front and back walls. Still further fold lines extend
transversely across the bottom wall and upwardly across the side
walls, and this arrangement permits folding of the construction
into a flat unit.
An additional fold line extends across the bottom wall between the
front and back walls. This fold line permits the bottom wall to be
forced upwardly, and this action operates to open the container.
Furthermore, the configuration described provides a locking action
which holds the container in the open position.
By providing a caricature on the exterior surface of the front
wall, and on at least the visible portion of the interior surface
of the back wall, the construction can be developed into an
amusement device. Specifically, the side walls can be cut away, and
relative vertical movement between the front and back walls can
then be achieved. If the caricature comprises a face, then the
expression thereof can be changed for amusement purposes.
The structure illustrated in the accompanying drawings comprises a
container 10 defining a front wall 12, a back wall 14, side walls
16 and a bottom wall 18. The top of the construction is open so
that food, for example French fried potatoes, can be loaded into
the construction. As best shown in FIG. 5, the construction is
manufactured from a one-piece blank 20. The front wall portion 12
of the blank is separated from the bottom wall portion 18 by means
of a first fold line 22. A corresponding fold line 22 separates the
bottom wall from the back wall portion 14. A second fold line 24
bisects the bottom wall 18 and extends between the front and back
wall portions. A third fold line 26 extends perpendicular to the
fold line 24.
The side walls 16 define a fourth fold line 28. As shown in FIGS. 1
and 2, this fold line 28 bisects the respective side walls when the
structure is in the assembled condition.
Fifth fold lines 30 extend along the intersection of the side walls
16 and front wall 12. Corresponding fold lines 30' are formed in
the side walls 16, and as shown in FIGS. 1 and 2, these fold lines
30 and 30' define the corners of the construction in its assembled
condition.
The blank 20 is also provided with a pair of tabs 32 which extend
outwardly from the edge of side walls 16 adjacent bottom wall 18.
As shown in FIG. 1, the tabs 32 extend outwardly over the bottom
wall when the structure is in the locked position, these tabs
serving as closing means for openings which are defined at the
bottom edge of the side walls where they intersect with the bottom
wall. The tabs 32 define a fold line 34 which is employed when the
structure is in the flattened position.
The blank 20 also includes flap portions 36 formed integrally with
the side walls 16. As shown in FIGS. 2 and 4, these flap portions
extend over the back wall 14, and a suitable adhesive is employed
for securing the flap portions to the back wall. This connection of
the flap portions to the back wall represents the sole means for
securing the container in the assembled condition.
In the preferred form of the invention, a caricature is displayed
on the container construction as shown in FIG. 3. This caricature
may comprise many different arrangements, and in some instances, it
may be accompanied by or replaced by printed advertising or other
information. The invention is used to best advantage, however, when
the caricature comprises a face having its major portion displayed
on the exterior surface of the front wall 12 with the upper lip of
the caricature extending along the upper edge of the front wall.
The lower lip and mouth of the caricature is then provided by means
of the extended portion 38 defined by the back wall.
A plurality of dots 40 extend around the limits of the caricature
for defining cut out lines. Similarly, dots 42 are provided on the
back wall, and when the structure is cut along the lines by these
dots, then the arrangement shown in FIGS. 6 and 7 is achieved. The
cutting operation removes substantially all of the side wall
portions, and relative vertical movement between the front and back
walls can then be achieved. With this arrangement, the expression
of the caricature can then be changed. It will be appreciated that
this provides increased appeal for the structure once it has been
used as a food container.
It will be understood that various changes and modifications may be
made in the above described construction which provide the
characteristics of this invention without departing from the spirit
thereof particularly as defined in the following claims.
