Claims
What I claim as new and desire to secure by Letters Patent is:
1. An improved, reusable, heart-shaped container for packaging
merchandise, said container consisting of:
a. a molded, foam polystyrene top section having a base wall and an
outwardly flared sidewall integral therewith, a plurality of said
top sections being nestable one within the other; and
b. a molded, foam polystyrene bottom section having a base wall and
an outwardly flared sidewall integral therewith, a plurality of
said bottom sections being nestable one within the other.
2. The containers in accordance with claim 1 wherein said sidewalls
of said top and bottom sections terminate in outwardly flared
peripheral lips.
3. The containers in accordance with claim 1 wherein said base
walls of said top and bottom sections include a recess therein and
wherein there is further included a decorative insert secured
within said recesses.
4. The containers in accordance with claim 1 wherein the sidewall
of at least one of said sections includes a plurality of bulges
directed towards said sidewall of said other section.
Description
This invention relates generally to containers and more
specifically to a foamed plastic box in the shape of a heart.
BACKGROUND OF THE INVENTION
Heart-shaped boxes are in great demand for the packaging of
Valentine's Day gifts, and in particular, candy. In the past the
boxes were generally assembled from pieces of cardboard, plastic or
the like. Frequently, combinations of cardboard and plastic were
used. While the prior art did in many ways provide the highly
desirable feature of reuseability, it did so at a considerable
cost, per box. Assembly time of the various components is chiefly
responsible for the relative costliness of the prior art structure.
The different types of material used also adds to the cost of the
prior art boxes.
The present invention fills a long standing need of the packaging
industry. Molded foam polystyrene is used to form top and bottom
sections of a heart-shaped box. The bulk of the candy for the St.
Valentine's Day market is packaged many months in advance, and then
it is stored under refrigeration. This places difficult demands on
the package. The package must not contaminate the product.
Additionally the package should be attractive, inexpensive and
reusable. The foamed polystyrene package of this invention meets
these requirements.
The foamed polystyrene is an excellent insulator and the resulting
package does not require outer insulated packing during the summer
season when a customer purchases a refrigerated package of candy
from a store.
In the present invention a peripheral lip is formed at the edge of
the inner box sections. This construction, which is obtainable
through existing technology, provides a seal between the two box
sections and thereby minimizes deterioration when perishable goods
are packaged. Similarly, a depression may very easily be formed at
the time of molding to accommodate a decorative insert that is
secured thereto by a suitable adhesive. Alternatively, the box
sections can be decoratively embossed or printed such as by silk
screening. The foamed polystyrene, while light in weight, is
sufficiently rigid to make reuse of the box practical.
Accordingly it is the primary object of this invention to provide
an improved container.
Another object of this invention is to provide the improved
container in the shape of a heart.
An additional object of this invention is to provide an improved,
heart-shaped box molded of foam polystyrene.
A further object of this invention is to provide an improved,
heart-shaped box, as described above, consisting of top and bottom
sections of unitary construction.
An advantage of this invention is that the top and bottom sections
are each nestable among themselves.
A feature of this invention is the provision of a peripheral lip to
provide means for sealing the interior of the box.
These and other features, advantages and objects of the invention
will, in part, be pointed out with particularity and will, in part,
become obvious from the following, more detailed description of the
invention, taken in conjunction with the accompanying drawing which
forms an integral part thereof.
In the various figures of the drawing, like reference characters
designate like parts.
BRIEF DESCRIPTION OF THE DRAWING
FIG. 1 is an exploded, perspective view of the top and bottom
sections of the box comprising this invention;
FIG. 2 is an exploded, sectional elevational view illustrating the
relationship of the top and bottom sections of this invention in
the assembled condition;
FIG. 3 is a fragmentary, sectional elevational view illustrating
the relationship of the top and bottom sections of this invention
in the assembled condition;
FIG. 4 is a fragmentary, sectional elevational view showing a
plurality of the top sections in a nested condition;
FIG. 5 is a fragmentary, sectional elevational view showing a
plurality of the bottom sections in a nested condition; and
FIG. 6 is a fragmentary elevational view of a typical box section
with the cover broken away illustrating an alternative form of
construction; and
FIG. 7 is a section taken along lines 7--7 of FIG. 6.
Turning now to the drawing there is shown a box 10 forming the
present invention. The box 10 consists of an outer or top section
12 and a bottom section 14 both of which are molded of foam
polystyrene in the shape of a heart. As is well known in the art,
the sections 12 and 14 may be molded or pressure formed between
male and female dies using foamed sheet polystyrene.
As is best shown in FIG. 2 the top section 12 is comprised of a
base wall 16 in which a recess or depression 18 is formed during
molding. The recess 18 is convenient for accurately receiving and
locating a decorative insert 20 which is secured thereto by means
of a compatible adhesive. A peripheral outwardly flared wall 22
depends from the base wall 16.
FIG. 2 also illustrates the configuration of the inner or bottom
section 14 which is comprised of a base wall 26 having a recess or
depression 28 formed therein during the molding operation. The
recess 28, like the recess 18, is sized and shaped to accommodate a
decorative insert 30. It should be noted that the provision of the
recesses 18 and 28, in addition to acting as locating means for the
inserts 20 and 30, serve to prevent inadvertent peeling of the
members secured therein. The base wall 26 of the bottom section 14
also includes an outwardly flared wall 32 integral therewith and an
outwardly flared lip or bead 34 at the extremity of the wall 32.
The tips 24 and 34 are both continuous about their respective walls
22 and 32.
The assembled relationship of the top and bottom sections 12 and 14
is shown fragmentarily in FIG. 3. It will be noted that the
outwardly flared lip 34 of the bottom section 14 fits snugly in the
corner defined by the juncture of the base wall 16 and the sidewall
22 of the top section 12. This construction very inexpensively
provides an effective seal for the contents of the box. The
frictional engagement also helps to hold the two sections 12 and 14
together.
FIG. 4 and FIG. 5 illustrate a feature of the present invention
that permits it to be used in conjunction with high-speed,
automatic filling machinery. Because the walls 22 and 32 are flared
outwardly, a plurality of respective sections can be nested
together. Reference characters 22a, 22b, 22c, 22d and 32a, 32b,
32c, 32d, illustrate the nested relationship that permits automatic
feeding of the two sections as required by the filling machine. In
this connection it will be appreciated that the outwardly flared
lip at the end of each sidewall serves the additional function of a
pilot when the sections are nested.
An alternative embodiment of this invention is shown in FIGS. 6 and
7. Sidewall 22', depending from base wall 26' is provided with a
plurality of outwardly bulged portions 36 that provide frictional
engagement with the sidewall of the mating section.
From the foregoing it will be apparent that an improved foamed
polystyrene container in the shape of a heart has been
provided.
There has been disclosed heretofore the best embodiment of the
invention presently contemplated. However, it is to be understood
that various changes and modifications may be made by those skilled
in the art without departing from the spirit of the invention.
