MOLD FOR INGESTIBLE SUBSTANCES
Abstract
A reusable molding kit and method of molding ingestible
substances. The kit comprises a central mold portion and a multiple
seal closure having a depressed portion which is inwardly directed.
The central mold portion has smaller and larger end openings either
of which can be sealed by the multiple seal closure. The depressed
portion in the multiple seal closure causes a hollow well to be
formed in the molded substance. The hollow well can be filled with
various different substances to give a pleasing appearance. The
depressed portion also serves as an additional mold for ingestible
substances. A multicolored molded substance may be formed by
filling the central mold portion with a moldable substance, filling
the depressed portion with a second moldable substance having a
different color, hardening the substances, removing the substances
and inserting the second substance into the hollow well formed in
the first substance.

Description
BACKGROUND OF THE INVENTION
1. Field of Invention
This invention relates to a method and a mold for producing
decorative effects in molded materials such as gelatin desserts and
ice and more particularly to a kit in which a variety of
configurations and combinations of moldable ingestible materials
may be produced. Foodstuff material of a congealable nature such as
gelatin desserts are particularly adapted for use with the mold and
kit of the present invention in a manner so as to produce a variety
of configured salad and dessert dishes.
2. Description of the Prior Art
Ice and foodstuff molds were known in the prior art, however, the
known molds lacked flexibility in producing a variety of
configurations of molded materials and were unable to produce ice
shapes which would float high in a liquid such as punch so that the
molded form of the ice could be seen. None of the molds known in
the prior art had a dual molding capacity so that one color of
molded foodstuff could be inserted into a different color of molded
foodstuff to produce a glistening marbled effect. Foodstuff molds
in the prior art which produced a ring shape had serious
disadvantages. The center of the ring was generally filled with a
material such as whipped cream or fruit. The hole in the ring went
completely through the molded material. When whipped cream or fruit
was placed in the center hole it would pass completely through the
molded material to the surface of the dish or other container. If
the ring was accidently moved the cream or fruit would become
wedged beneath the molded material causing a messy unpleasant
appearance. Foodstuff molds in the prior art had a further
disadvantage in that when the center was filled with a material
such as whipped cream or the like the cream would have a tendency
to become dry at its surface. None of the molds in the prior art
had a reversible seal which could produce a storage space for
whipped creams, fruit or another molded material which opened
either from the top or from the bottom. None of the molds for
congealable foodstuff or the like could be used to form either a
solidly molded material, a ring, or a configuration having a large
storage space with either a top or bottom opening which could be
filled with fruit, whipped cream or the like and which did not pass
completely through the molded material. None of the molds in the
prior art had a dual molding capacity in which either molding
compartment could mold a substance having a pattern such as a star
in its surface. None of the molds in the prior art could produce a
molded shape of two different colored congealable substances in
which the top central portion of the molded material was a flat
surface having a different color than the surrounding molded
material. In the prior art foodstuff molds which had patterns on
the seal could not be easily filled. When the seal was placed on
the filled mold the pattern which projected into the liquid which
was to congeal displaced a portion of the congealable liquid
causing the liquid to run down the outside surface of the mold.
None of the molds in the prior art could be used alternatively as
molds for congealable foodstuff and for ice or other materials
wherein the formed ice had a storage space which could hold fruit
or the like while the ice was floating in a liquid such as
punch.
BRIEF DESCRIPTION OF THE INVENTION
This invention relates to a reusable molding kit for ice and
foodstuffs of the type that are introduced into a mold as a
moldable material and formed in the mold to a shape-retaining solid
conforming to the contours of the mold. The molding kit includes a
multiple-seal closure which can seal either the larger or smaller
opening in a central mold portion. The multiple-seal closure has a
depressed portion inwardly directed from a centrally located hole
located in a dish-shaped sealing wall. The depressed portion
extends into the central mold portion when the multiple-seal
closure is engaged with either the smaller base opening or the
larger opening of the central mold portion. When the mold is filled
with water, gelatin dessert or other ingestible material which
subsequently congeals or hardens to a shape retaining solid, the
molded solid has an inwardly directed hollow portion.

PREFERRED EMBODIMENT
In the preferred embodiment of this invention the reusable molding
kit for ice and foodstuffs of the type that are introduced into the
mold as a moldable material and formed therein to a molded shape
retaining solid is fabricated from plastic materials and as best
seen in FIGS. 1, 3 and 5 includes a central mold portion 10, a
multiple-seal closure 15, a substantially flat plastic closure 28
and a base seal 29. The central mold portion 10 is contoured from a
larger opening 11 at one end thereof to a smaller base opening 12
at the other end. The larger opening 11 is provided in the central
mold portion 10 for the removal of the shape-retaining product from
the mold. The larger opening 11 is defined by an upstanding
peripheral rim 13 and the smaller base opening 12 is defined by
downwardly extending peripheral rim 14. The smaller base opening 12
and the integral downwardly extending rim 14 are adapted to
maintain the central mold portion 10 in a stable-resting position
when placed on a supporting surface.
As shown in FIGS. 3, 5 and 6, multiple seal closure 15 has a
disk-shaped sealing wall 16 which includes substantially flat inner
and outer surfaces 17 and 18 and a peripheral edge 32. The
disk-shaped sealing wall also has a centrally located circular hole
19 passing from outer surface 18 to inner surface 17 and a rim 20
upstanding from outer surface 18 and attached to the periphery of
centrally located hole 19. A cup-shaped central portion 21 is
inwardly directed from disk-shaped sealing wall 16. Cup-shaped
central portion 21 has a base peripheral edge 22 and terminates in
a hemispherical end wall 23. A connecting wall 24 joins upstanding
rim 20 and base peripheral edge 22 to form central U-shaped groove
25 which opens on inner surface 17 of disk-shaped sealing wall 16.
Central U-shaped groove 25 is adapted for sealing engagement with
peripheral rim 14 of smaller base opening 12. Disk-shaped sealing
wall 16 also has a peripheral U-shaped groove 26 opening on inner
surface 17 proximate peripheral or circumferential edge 32 of
disk-shaped sealing wall 16 which is adapted for sealing engagement
with upstanding peripheral rim 13 of larger opening 11 when central
U-shaped groove 25 is disengaged from downwardly extending
peripheral rim 14. An intermediate opening 27 passes through
disk-shaped sealing wall 16 between central U-shaped groove 25 and
peripheral U-shaped groove 26 which permits the mold to be easily
filled when multiple seal closure is engaged with larger opening
11.
As previously mentioned the molding kit preferably includes a
substantially flat plastic closure 28 for engagement with
upstanding peripheral rim 13 in a moisture-tight sealing
relationship and may be employed subsequent to removal of the
multiple-seal closure 15 after molding or alternatively when either
closure 15 or seal 29 are used on opening 12 during molding.
The kit also includes base seal 29; FIGS. 1, 2, 3, 4, 7 and 8; for
smaller base opening 12. Base seal 29 has base seal U-shaped
peripheral groove 30 adapted to engage with downwardly extending
peripheral rim 14 in a moisture-tight sealing relationship when
multiple seal closure 15 is engaged with upstanding peripheral rim
13. Base seal 29 preferably has a central wall 31 configured to
form a design on the molded product, however, a plain seal may be
similarly employed.
If desired, multiple-seal closure 15 need not be used and base seal
29 can be used to seal smaller base opening 12 while substantially
flat plastic closure 28 is being used to seal larger opening
11.
In an alternative embodiment, FIGS. 7 and 8, it is contemplated
that the base seal 29 may also be used to form a configured pattern
in a solid formed in depressed cup-shaped portion 21. This
particular embodiment includes a sealing flange 34 that extends
outwardly from the connecting wall 24 of the multiple-seal closure
15. The flange 34, as is readily apparent from FIGS. 6 and 7, is
adapted to matingly receive the base seal 29 or a similar seal in a
substantially air-tight relationship. Thus, it is possible in one
aspect of the invention to simultaneously but separately mold
congealable material in the central mold portion 10 and in the
multiple-seal closure 15. Further, the material molded in the
cup-shaped portion 21 may be configured using the base seal 29.
It has been discovered that a molding kit in accordance with this
invention makes possible several unique and unexpected results. For
example, an unusual shimmering multicolored molded gelatin dessert
can be prepared by molding a gelatin dessert having one color in
the central mold portion and subsequently filling the hollow well
portion in the molded gelatin dessert with a molded gelatin dessert
having a second color formed in the shape of the hollow well
portion. The gelatin dessert having the second color may be molded
in the depressed portion of the reversible seal. Since the
multiple-seal closure may be placed on either the smaller base
opening or the larger opening of the central mold portion the
hollow well portion in the molded ice or foodstuff may be in either
the top or bottom surface of the molded material. The gelatin
dessert having a different color may be placed in either the top or
the bottom of the molded material having the first color depending
upon whether the multiple-seal closure was placed on the smaller
base opening or the larger opening of the central mold portion. Two
multicolored molding effects may, therefore, be obtained from the
same molding kit.
As was discussed in the previous paragraphs the molding kit has a
dual molding capacity in that a material may be molded in the
central mold portion while another material is being molded in the
depressed portion of the reversible seal.
The multiple-seal closure gives the molding kit additional
flexibility in that the hollow well may be formed in either the top
or bottom surface of the material which is molded in the central
mold portion. Many of the effects possible with the molding kit are
obtainable, however, when the seal having the depressed portion is
not reversible but can be placed on only one end of the central
mold portion. Further, it should be noted that an integral
construction employing an inwardly directed depressed portion
extending from the smaller end of the mold will similarly yield
pleasing results. Such a well might also include a sealing flange
to accommodate a seal, thus retaining the dual molding capability.
The integrally connected depressed portion should extend over
one-half of the distance from the smaller end to the larger end of
the mold.
A molded congealable foodstuff having a hollow well portion in the
top has particular advantages in that the well portion can be used
as a storage space which gives a particularly pleasing aesthetic
appearance. The hollow portion can be used to store such things as
fruit or whipped cream. When the hollow well portion appears in the
top of the congealable substance such as gelatin dessert another
advantage was unexpectedly discovered. Substances such as whipped
cream do not pass completely through the molded foodstuff to the
plate below thus unsightly smearing of substances such as whipped
cream on the plate does not occur. Molded ice having a hollow well
portion in the top also has similar advantages. The molded ice can
be floated in a punch bowl and the hollow well portion in the
molded ice can be used as a storage space which gives the punch
bowl an interesting, unusual and pleasing appearance.
A hollow well portion in the bottom of a congealable foodstuff such
as a gelatin dessert also has particular advantages. When the
hollow well portion is filled with substances such as fruit,
whipped cream or the like a particularly pleasing appearance
results. The fruit or whipped cream is viewed from the top through
the gelatin dessert or the like which gives an interesting and
unusual effect. In addition substances such as whipped cream have a
tendency to dry when exposed to air. When the cream is stored in a
well formed in the bottom of the foodstuff such as gelatin dessert
or the like exposure to the air is eliminated.
It was unexpectedly discovered that a well portion formed in the
bottom of molded ice had a particular advantage. When the ice is
placed in a liquid such as punch or the like it floats higher thus
exposing the molded ice form.
If for some reason a ring structure is desired, the reversible seal
may be placed on the smaller base opening and the mold may then be
partially filled to form a ring.
As indicated above it is preferred that a seal for the smaller base
opening be provided with the molding kit. The smaller vase seal is
used to seal the smaller base opening of the central mold portion
when the multiple-seal closure is engaged with the larger end
opening. The smaller base seal may be provided with a pattern which
imparts an aesthetic appearance to the top of the molded ice or
moldable foodstuff. The smaller base seal may be used to seal the
depressed cup portion in the multiple-seal closure thus permitting
a molded pattern to be formed in ice or a molded foodstuff which is
molded in the depressed cup portion of the multiple-seal
closure.
