Description
This invention relates to a novel and useful ice molding apparatus
to be utilized in conjunction with an upstanding open top container
and the apparatus includes a plurality of selectively and
reversably superimposable planar and pocketed panels. The ice
molding apparatus may be utilized without the planar panels (in
which instance only the pocketed panels are used) or with the
planar panels disposed between adjacent pocketed panels. When only
the pocketed panels are used with the pockets of adjacent panels
registered and opening toward each other double size ice cubes as
well as single size ice cubes may be formed. In addition both
double and single size cubes may be formed when the planar panels
are also used, although a larger percentage of single size cubes
are formed when the planar panels are used. Still further, when a
planar panel is disposed between the pocketed panels of each pair
of adjacent panels only single sized ice cubes will be formed.
The ice molding apparatus of the instant invention is constructed
in a manner whereby the ice cubes formed thereby may be readily
broken loose from the molding apparatus and the latter is
constructed in a manner whereby it may be utilized in conjunction
with upright containers such as discarded milk cartons enabling the
ice molding apparatus and the associated milk carton to be stored
in an area having greater height than length or width.
The main object of this invention is to provide an ice molding
apparatus specifically designed for use in conjunction with an
upstanding milk carton or other similar container.
Another object of this invention is to provide an ice molding
apparatus constructed in a manner whereby different shaped ice
cubes of single and double volume size may be selectively formed
according to the manner in which the various panels of the
apparatus are disposed within the upright container to be used in
conjunction therewith.
A further object of this invention is to provide an ice molding
apparatus constructed in a manner whereby the various ice cubes
formed thereby may be readily dislodged therefrom.
A still further object of this invention is to provide a ice
molding apparatus adapted to be utilized in conjunction with
normally discarded milk cartons or the like.
A final object of this invention to be specifically enumerated
herein is to provide an ice molding apparatus in accordance with
the preceding objects which will conform to conventional forms of
manufacture, be of simple construction and easy to use so as to
provide a device that will be economically feasible, long lasting
and relatively trouble-free in operation.
These together with other objects and advantages which will become
subsequently apparent reside in the details of construction and
operation as more fully hereinafter described and claimed,
reference being had to the accompanying drawings forming a part
hereof, wherein like numerals refer to like parts throughout, and
in which:
FIG. 1 is a perspective view of one of the pocketed panels of the
ice molding apparatus as seen from the rear side of the panel;
FIG. 2 is a perspective view of the pocketed panel as seen from the
front side thereof;
FIG. 3 is a perspective view of the planar panel of the ice molding
apparatus;
FIG. 4 is a vertical sectional view taken substantially upon a
plane passing through the center of a disposable milk carton which
has had its upper end removed therefrom and with a plurality of the
planar and pocketed panels disposed within the carton;
FIG. 5 is a horizontal sectional view taken substantially upon a
plane indicated by section line 5--5 of FIG. 4;
FIG. 6 is a perspective view of a double size ice cube formed in
conjunction with the ice molding apparatus of the instant
invention;
FIG. 7 is a perspective view of a single size ice cube formed with
the molding apparatus of the instant invention;
FIG. 8 is a fragmentary perspective view of a further upright
carton having a plurality of modified molding panels disposed
therein; and
FIG. 9 is a fragmentary vertical sectional view similar to FIG. 4
but illustrating the manner in which five pocketed panels of
slightly less thickness may be received within a carton such as
that illustrated in FIG. 4 without a planar panel also being
used.
Referring now more specifically to the drawings, the numeral 10
generally designates the ice molding apparatus of the instant
invention which includes an upright upwardly opening carton 12, a
plurality of pocketed panels 14 and which may also include a planar
panel 16, see FIG. 4.
The carton 12 may comprise a discarded pasteboard milk carton of
the plastic or wax coated type which has had its upper end removed
therefrom or unfolded to the fully open position. The carton 12
illustrated in FIGS. 4 and 5 has a first right hand pair of panels
14 disposed therein and a second left hand pair of panels 14
disposed therein with a single planar panel 16 interposed between
the adjacent pairs of panels.
From FIGS. 1 and 2 of the drawings it may be seen that the panels
14 have vertically spaced rows of transversely spaced apart areas
20 displaced outwardly to the back side of the panel whereby
correspondingly forwardly opening pockets 22 are defined. Each of
the pockets 22 includes a bottom wall 24, upper and lower end walls
26 and 28, and opposite side walls 30, see FIGS. 4 and 5. The walls
26 and 28 are slightly convergent toward the bottom wall 20 as are
the walls 30. Thus, the pockets 22 are isosceles trapezoidal in
horizontal and vertical cross sectional shape as taken upon planes
disposed normal to the bottom wall 24. In addition, with attention
now invited more specifically to FIG. 1, a plurality of rearwardly
opening pockets 32 of similar shape are defined between the areas
20 on the back sides of the panels 14.
Thus, when the panels 14 and 16 are disposed within the carton 12
as illustrated in FIG. 4 of the drawings, single size ice cubes
such as that designated as at A are formed in the pockets 32 and
double size ice cubes such as that designated B in FIG. 6 are
formed in the double size pockets formed by the opposing pockets
22, see FIG. 4. Of course, if the panels 16 were removed, double
size ice cubes such as ice cubes B would be formed in the opposing
pockets 32 in the center of the container 12 while the single size
ice cubes A would be formed in the pockets 32 which open toward the
sides of the container 12.
The panels 14 and 16 are of course to be constructed of any
suitable material such as plastic which is reasonably stiff and yet
resilient and from which ice cubes formed in the container may be
readily separated. Further, inasmuch as the carton 12 comprises a
milk carton or the like, it may be readily torn to quickly remove
the panels 14 and 16 as well as the ice cubes formed thereby. On
the other hand, if it is desired to re-use the carton, after the
entire assembly 10 has been removed from the freezer, it may be
allowed to set at room temperature for 5 or 10 minutes during which
time the fiberous walls of the container 12 will transmit
sufficient heat to loosen the walls of the container 12 from the
ice cubes and adjacent portions of the panels 14 whereby the panels
14 and 16 may be readily withdrawn from the open upper end of the
container 12.
With attention now invited more specifically to FIG. 9 of the
drawings there will be seen a plurality of panels 14' which are
substantially identical to the panels 14 except that the pockets
22' and 32' formed thereby are not as deep as the pockets 22 and
32. Accordingly, five of the panels 14 may be received within the
carton 12 and in this manner a greater number of single and double
size ice cubes similar to ice cubes A and B may be formed without
utilizing one of the planar panels 16.
With attention now invited more specifically to FIG. 8 of the
drawings, there will be seen a plurality of still further modified
panels 40 which may be considered somewhat corrugated in form and
may be nested within the container 12 so as to divide the interior
of the latter into a plurality of individual compartments in which
water may be frozen to form cylindrical ice cubes as well as ice
cubes of a shape corresponding to the voids between those adjacent
panels 40 arranged in back-to-back relation.
Thus, if may be seen that numerous shapes of ice cubes may be
formed by utilizing divider panels of various configurations within
an upstanding carton such as a discarded milk carton which has had
its upper end removed or unfolded to the fully open position. Of
course, suitable other cartons made especially to receive the
panels 14 and 16 may be used. Such other cartons may also be
constructed of stiff but resilient plastic material which will
separate readily from the ice cubes to be formed and such other
cartons will of course be re-usable.
With attention again invited to FIGS. 1-3 of the drawings it will
be noted that each of the panels 14 and 16 includes an upwardly
projecting tab portion 42. These tab portions project above the
upper end of the container 12 as illustrated in FIG. 4 of the
drawings and are of course provided to enable the panels 14 and 16
to be readily withdrawn from the container 12. In addition, the tab
portions 42 are provided with apertures 44 whereby they may be
readily stored on a nail or hook in an otherwise unusable storage
space. Further, the apertures 44 may be utilized to hang the panels
14 and 16 while drying after being washed.
The foregoing is considered as illustrative only of the principles
of the invention. Further, since numerous modifications and changes
will readily occur to those skilled in the art, it is not desired
to limit the invention to the exact construction and operation
shown and described, and accordingly all suitable modifications and
equivalents may be resorted to, falling within the scope of the
invention as claimed.
