Patented Apr. 24, 1951 DEVICE FOR CHILLING LIQUID COMESTIBLES Albert M. Zalkind, Arlington, Va.
Application July 15, 1944, Serial No. 545,055
This invention relates to devices for chilling liquid comestibles and more particularly to those devices in which ice is used for obtaining the cooling effect. It is an object of my invention to provide a, container adapted to hold a quantity of water for freezing into an ice mass therein when the container is placed in a refrigerator, and proriding such container with means for directing liquid comestibles to andfrom the interior thereof whereby the comestibles are chilled by contact with the ice mass therein. Another object of my invention is to provide a device for chilling liquid comestibles rapidly and conveniently. A further object of my invention is to provide a structure adapted for ready rinsing to enhance cleanliness thereof. A still further object of my invention is to provide a compact structure suitable to be manufactured by mass production methods.
In accordance with the above objects, I provide various embodiments of a device having features in common, viz., a substantially rectangular container of sheet aluminum or equivalent material having at least one large flat exterior surface for contact with the freezing shelf of a refrigerator and adapted to have a quantity of water poured into the interior of the container through an opening provided at one end thereof. By placing the container thus charged with water in a horizontal position with the large flat area in contiguity with the freezing shelf Of a refrigerator, I obtain a block or slab of ice therein having a relatively large surface area exposed in the interior of the container. The container may then be removed from the refrigerator and rested in substantially vertical position, whereby a quantity of relatively warm liquid comestible may be conveniently poured through the opening into contiguity with the slab of ice. Inasmuch as the container is substantially closed except for the end opening, the comestible is retained therein and becomes chilled by contact with the ice, and the container may be agitated to effect rapidity of heat transfer. After the comestible is thus chilled, it may be poured out of the container into a tumbler or other drinking vessel.
Other objects and features Of my invention will be apparent from the detailed description which follows with reference to the appended drawings in which:
Fig. 1 shows an embodiment of my invention, in the preferred form, adapted to retain two parallel slabs of ice; I
Fig. 2 shows a section through 1-2 of Fig.1;
Fig. 3 is a section through 3-3 of Fig. 2;
; Fig. 4 shows a modified funnel for use in conjunction with various embodiments of my device;
Fig. 5 shows a further embodiment of my invention adapted for use in conjunction with the modified funnel of Fig. 4;
Fig. 6 shows a still further embodiment of my invention; and I Fig. 7 shows a section through XX of Fig. 6. With reference to Figs. 1, 2, and 3, a. container I is shown of substantially rectangular-shape having a funnel-shaped opening 2 with a constricted portion 2d at one end thereof and having relatively large fiat wall areas 3 and 4 and side walls Stand 6. A plurality of ice retaining lugs 3a, b, c, and d, and 4a, b, c, and d, substantially wing-shaped, as shown, are secured to the interior surfaces of the walls 3 and 4 ofv the container by soldering, spot welding, or the like. A spreader bar 9 is secured between the walls 5 and 6 interiorly of the container and disposed below the constricted portion of the funnel-shaped opening 2. Ice blocks or slabs A and B having substantially flat parallel surfaces facing interiorly are shown retained within container l jby virtue of having been frozen around the retaining lugs. The manner of obtaining the ice slabs A and B in the container I is as follows: with the container in a substantially vertical position, as shown in Fig. 1, a charge of water is poured through the opening 2 and then frozen into the slab of ice A by placing the container with the surface 3 horizontal upon the freezing shelf in of a refrigerator, as shown in Fig. 3. It will be understood that the initial charge of Water, can be any amount up to the point where it commences to spill over the constrictionjZaQbf the funnel shaped opening when the container I. is horizontally disposed on the freezing shelf jlll. After the slab A has been obtained, the container is removed from the freezing shelf and is once more held in a vertical position and another charge of water poured in, the slab of ice A being retained in position by means of the lugs 3a, b, c, and d. The container is then returned to the freezing shelf in inverted relation to the view shown in Fig. 3 so that the surface 4 is now in contact with shelf Ill, whereby the new charge of water will be frozen into the ice slab B and retained in the container by the lugs to, b, c,-and d. In this manner I obtain a container having two relatively large substantially parallel ice blocks each filling approximately one-third the interior volume of the container with a space therebetween of approximately one-third the interior volume thereof. 'In use, thecontainer l is held vertical (Fig. 1) and a warm comestible poured through the opening 2 into the space between the i-ce slabs A and B, impinging during the pouring process (Fig. 2) against the spreader bar 9 which has the effect of causing the comestible to be directed against the ice slabs at the top thereof and cascade downwardly in contact therewith. The container may be agitated to hasten the chilling effect and when suitably cooled the comestible may be poured out through opening 2 into a drinking vessel.
Melting of the ice slabs takes place during the process of cooling a comestible, and sufiicient melting may occur to loosen the grip of the walls of the container on the ice slabs. Due, however, to the restraining action of the retaining lugs,- the ice slabs are prevented from floating upwardly to choke or constrict the opening 2a. Should the slabs break away from the lugs due to substantial melting or rough handling, bar 9 will effectively block them from closing the opening 2a when the chilled comestible is being poured out of the container;
With particular reference to Fig. 2, the base of the container l is shown as having a central aperture I2 closed by a closely fitting plug l3. The aperture and plug are provided for the purpose of enhancing rinsibility of the device, since by removing plug I3 flow of water from a sink tap can be directed through the opening 2, draining downwardly through th container and washing the ice surfaces and the walls, the plug being removed to permit continuous draining. The par ticular function of the plug is to prevent leakage through the aperture when the container is being charged with water for freezing therein in the manner heretofore described. Also, providing an aperture as shown renders the device capable of having a comestible continuously poured therethrough, container 1 being held vertically over or resting on the edges of a receiving receptacle and the chilled comestible draining thereinto. Rinsing may also be accomplished in the same manner that a bottle or other elongated vessel would be rinsed, namely, by pouring clean water thereinto and shaking the container, thereby agitating thewater to scour the interior.
After rinsing, the container is charged with a quantity of water to compensate for loss of ice due to melting, the correct quantity being determined by pouring an excessive quantity of water therein while it is in the vertical position and then holding it with either wall 3 or lhorizontal to permit the excess to drain out through the opening 2. The ice slabs A and B are replenished alternately in this manner, fresh ice being formed adhering to one or the other of the ice slabs after each use.
In Fig. 4 is shown a modified flow directing means comprisin a funnel-shaped structure l5 of generally trapezoidal configuration having a depending channel [6 provided with a plurality of perforations [1. The structure shown in Fig. 4 may be used in conjunction with the container I by being inserted in the funnel-shaped opening 2 with the bottom of the channel 16 resting on the spreader bar 9, for the purpose of straining the comestible. Further, the structure shown in Fig. 4 could be used in conjunction with a container in which the upwardly flared position of the opening 2 and the spreader bar Bare eliminated, as illustrated in Fig. 5. By elimination of the upwardly flaring portion of the opening 2, the over all length of the container is shortened, it being understood that the modified flow directing means is removed when the container is placed on the freezing shelf of a refrigerator.
With reference to Figs. 6 and '7, a substantially rectangular container 20 is disclosed having a completely open upper end 2| adapted to have fitted therein, with sliding, but sealing fit, a plug 23 having a funnel-like interior structure 24 and ice retaining grids 25 and 2G integrally secured thereto protruding into the container 20. A container 23 is provided having an opening 29 adapted to fit over the opposite end of the plug 23, with a sliding, but sealing fit, as shown. A block of ice C is frozen in the interior of the container 20 around the grids 25 and 26 in the same manner as the block A or B was frozen in the container in the form shown in Fig. 1, the container 28 being removed from the plug 23, and not forming part of the structure, when the container 20 is in the refrigerator. In use, a warm comestible is poured into the container 28 which is adapted to rest on the end 3E, and the container 29 having been removed from the refrigerator, is held in vertical alignment over container 23 and joined thereto by sliding plug 23 into aperture 29. As viewed on Fig. 5, the assembled structure would then be upside down. The whole structure is then turned end over end several times and shaken so that the comestible is thoroughly agitated and uniformly chilled, whence the assembled structure is again held vertical permitting the comestible to drain entirely into container 28, the structure then being disassembled and the chilled comestible poured out of container 23 as desired. In this manner, a volume of comestible larger than the volume of free space in container 2s may be conveniently chilled. Plug 23 may be made of plastic material, or the equivalent, and the grids 25 and 26 of flexible stainless steel, so that as the comestible warms the sides of the container 20 and the ice block C melts away therefrom, it is free to swing in space although re strained from floating upwardly to constrict the opening, whereby th comestible has access to substantially the entire surface area of the ice block. Alternatively, the rids 25 and 26 may be hinged in any suitable manner to the plug 23 to perform the same function. It is to be understood that although two grids 25 and 26 are shown, in practice the device is not limited to any specific number. A feature of the structure resides in the fact that, after use, plug 23 may be pulled out of the container 23, the ice block C remaining attached to the plug and being exposed for convenient and thorough rinsing.
