U.S. Pat. No. 6,763,675, John H. Fleeman, Apparatus and Method for Preparing, Chilling and Dispensing a Beverage
The invention described herein relates generally to beverage dispensing devices and, more particularly, to reusable chilled beverage dispensers. In particular it relates to beverage dispensers which may be used in a drinking establishment or party environment, which combine elements of decor or aesthetics with those of beverage cooling in a visible way. The dispensing part of the invention is via gravity induced flow, as opposed to pumps or pressurization. Beverages as used herein refers to a liquid suitable for human consumption and also refers to any components or mixtures of such liquid, while liquid refers to any mixtures of liquids, colloids and solids, including but not limited to slushy drinks composed of ice/liquid mixtures or milkshakes, capable of flowing via gravity. Said liquids may contain dissolved gasses or solids, as well as decorative components harmless to humans including but not limited to glitter or coloring agents.
Ice sculptures are popular at drinking establishments or in party environments for the reasons discussed above. One popular way to perform the function of cooling while displaying a beverage at a party is an ice luge. An ice luge is typically a block of solid ice with one or more troughs carved or molded into a surface of the block of ice. The block of ice is then tilted on an angle and set on a slope so that a beverage can be poured into the one or more troughs. As the beverage flows down the one or more troughs, the ice block cools the beverage flowing down the one or more troughs. A person or people may position their mouths or a glass at the end of a respective trough to catch the beverage at is leaves the end of the respective trough. In other examples, blocks of ice may be formed with tubes or tunnel running through the interior portion of the ice block. Beverages are poured into the tube and are chilled as the beverage passes through the tube or tunnel within the ice block.
Generally, these ice blocks are formed in molds or carved by hand. As the ice melts the melt water runs along the table on which the ice block is placed. As such provisions must be made to contain the melt water so as to avoid damage to floors, tables, rugs, etc. In addition, the ice blocks generally can be used only once due the perishable nature of the ice block, requiring availability of a mold and storage for same, or a skilled ice carver for each event. Other disadvantages of the traditional system of using solidified blocks of frozen material include those discussed in U.S. Pat. No. 6,763,675, John H. Fleeman, Apparatus and Method for Preparing, Chilling and Dispensing a Beverage, which refer to risks of either diluting the beverage being poured down the block due to melting of the frozen material or freezing out certain components if the frozen material is extremely cold, for example, dry ice. Meanwhile, although a sculpture of ordinary material such as Lucite can be used, again as referenced in U.S. Pat. No. 6,763,675, this does not perform the function of cooling a beverage, which is important for the chilled beverage dispenser which is the subject of this invention.
It would be advantageous to have a reusable beverage chilling device into or into which a beverage can be poured and chilled as the beverage is flowing through the device.
The present invention solves these and other problems as described below. One embodiment of this invention uses one or more containers shaped in the form of a slab of an ice luge. This container would have some premade combination of channels on one or more surfaces and tubes through which a beverage could flow. Such a container is filled with a fluid, including, but not limited to, water, and chilled or frozen in a suitable location such, but not limited to, a refrigerator or freezer. This container is then placed on a stand which tilts it such that beverages can be poured onto or into the passageway, flowing to the bottom where said beverages are drunk or decanted into a container, while keeping said beverages out of contact with said fluid providing a chilling effect. Different types of ends can be placed on the outlet of the channels or tubes, including ones shaped for pouring into a glass or ones shaped for drinking directly from the outlet of the channel or tube, said ends shaped for drinking directly from said outlet potentially being used by each individual for sanitary reasons.

The present invention and its various embodiments are described below, with reference to figures as necessary. Reference numbers are used to match particular elements described in the text with those shown in figures. Although the embodiments disclosed will be described with reference to the embodiments shown in the drawings, it should be understood that the embodiments disclosed can be embodied in many alternate forms of embodiments. In addition, any suitable size, shape or type of elements or materials could be used.
Generally speaking, the present invention describes an apparatus and associated methods of construction and operation for dispensing a chilled beverage. More particularly, this invention applies to a beverage chilling system intended partially for decorative and display use and making use of gravity to dispense the beverage, rather than a conventional industrial refrigerated system for pressurized or pumped beverage dispensing. The beverage so dispensed may arrive in one or more receptacles such as glasses, or be drunk directly from the outlet(s) of the apparatus.
In this example, the beverage dispenser includes a stand 103 for supporting the container 100 thereon. It is noted that while the container 100 is shown as being separate and distinct from the stand, in alternate embodiments the one or more containers may be formed integrally with the stand in a unitary construction so that the container 100 has a substantially flat base and an angled top surface. It is also noted that while stand 103 is shown as a single piece, it can be rigid or collapsible, can be built to fold for storage, and can also be built as part of the container 100, i.e. the container can have panels which fold downwards in a variety of configurations known to those skilled in the art in order to support itself. The visible surfaces of the stand may be textured in such a way as to match or complement the container. The frame may have any suitable shape and size and be constructed of any suitable material including, but not limited to, metals, plastics, wood and composites. The surface supporting the container may take several forms including, but not limited to, a solid surface, a frame with solid side panels, a frame with legs, or individual legs attached to the container. The stand 103 is shown to have flanges or brackets 104 in order to hold the container 100 in place when the container is tilted. These flanges can take many forms known to those skilled in the art, including being hidden under the container on the stand surface where they could take forms including, but not limited to, one or more wires such as are used in hanging a picture, interlocking grooves, or magnets. It is also possible to make the stand such that the tilt angle of the container on top is adjustable, or to interchange stands to change the tilt angle of the container. This would allow the container 100, for example, to have a steeper slope if used for a relatively viscous beverage such as a frozen Daiquiri or a milkshake, and a shallower one for a pure liquid such as lemonade. It would also allow for adjustment of tilt angle if necessary for particular configurations of troughs or tubing on or in the container which may have shallower or steeper angles in them, such that they can empty fully. As with the container itself the stand can be made in such a way that it disassembles into pieces for display, storage or transport. Finally, it is possible to mount the container on a pivot or axel such that its tilt could be adjusted while in use or on display, perhaps revealing a particular picture or pattern only when desired as part of the exhibition, or even reversing the inlet and outlet of the dispensing system.
The container 100 may be a hollow container having any suitable size and shape and be configured to contain or house a cooling fluid or gel. This fluid or gell should have high heat capacity, ideally undergoing a phase change which stores large amounts of energy, such as but not limited to water, which freezes into ice. The container may also be refillable and thus equipped with fill and/or drain plugs to facilitate addition and removal of a particular cooling fluid. It may also be desirable to use solid materials such as dry ice inside the container to chill it, and a completely solid object can be used for this dispenser for reasons of convenience but is likely to be less advantageous for reasons of lower total heat capacity then a material capable of undergoing a phase change. The container 100 may be formed in any suitable manner including, but not limited to, blow molding, bending, stamping, welding, extruding, etc. The container 100 may have funnels or other larger openings 105 and 106 to facilitate pouring a beverage into the upper end of the channels 101 and 102 The container 100 may also be constructed of any suitable material including, but not limited to, plastics, composites, metals, vinyls, acrylics, or any other suitable material. It is desirable to make the container 100 out of a material with good heat transfer, such as metal, but metals may transfer an unpleasant taste to the beverage, so it may be desirable to use a non flavor inducing coating on the container. This coating may be applied to the entire container 100, or just to the side with troughs, or just to the troughs 101 and 102. It may be important to use a “food grade” coating for this coating or the entire material of the container, as it will be in contact with beverages intended to be drunk by humans. It may also be important to use a material which can be cleaned and sterilized, since a primary purpose of the invention is to provide a reusable beverage chilling and dispensing system. The container may have insulation on one or more sides to prevent heat loss and condensation. In particular it may have insulation between it and the stand, on the sides, and on the front or top surface, with the exception of on the passage surfaces where heat transfer from the beverage through the container wall to the fluid or solid inside may take place. In particular this insulation could be designed to enhance the theme of the dispenser, for example foamy material if it is to be used as a display for a bubble bath product or a beer. In one example, the walls of the container 100 may be transparent, translucent, opaque or otherwise configured so the walls are substantially solid in color. The walls of the container 100 may be configured with any suitable textures, patterns or other visual features. For example, the container 100 may be textured such that the containers mimic a block of ice or any other suitable item. The texture may include graphics, text or other indicia. In another example, the container 100 may include a colored cooling fluid or a cooling fluid having glitter or other visual effect such as UV active fluorescent dyes as is known in the display arts. Thus, although it is likely that due to wide availability, low cost and a freezing point which is accessible in a wide variety of commercial refrigeration apparatus, water will be a major component of the fluid used in the container, other materials may be added to it for reasons including, but not limited to, stability (e.g. a biocide), visual decoration, or viscosity changes. The amount of said additives may vary depending on the effects which are desired. In still other examples, lighting may be placed within or behind the container 100 or under, behind or inside stand 103 for ambience lighting or otherwise visually stimulating users of the beverage dispenser 100.
While troughs 101 and 102 are shown in this example, it is possible to use channels of a variety of cross sections including, but not limited to, U shaped and V shaped. It is also possible to use enclosed tubes for part or all of the passage of the liquid. If tubes are used, this also allows for the possibility of more complex 3-dimensional patterns in the container 100, as they can cross each other. It also allows for the outside surface of the container to remain flat, which may permit some decorative designs or effects which would otherwise be difficult. Said 3-dimensional patterns could include, but are not limited to, spirals, zigzags, and shapes matching pictures or figures on surfaces of the container 100. More complex, lengthy passages allow both for more elaborate displays and more effective cooling of the beverage due to longer times in contact with the cooling surface. The term passages will be used in this patent to refer to any shaped surface including, but not limited to, channels, troughs, passages and tubes along which or through which beverages can pass by gravity. The container can also be made with channels on its back surface, facing the stand. This allows both for more than one pattern to be made on a container, increasing its flexibility of usage, and if the seal between the container 100 and the stand 103 is liquid tight, usage of the channels on the rear of the container 100 to chill beverages as well as the channels 101 and 102 depicted on the front.
It is also possible to produce textures in or on the surfaces of the passages, such as but not limited to, ridges, stair steps, and cooling fins. These textures can have purposes such as, but not limited to, enhancing the decorative nature of the invention, causing turbulence to aerate the beverage flowing over them or improve heat transfer, and increasing surface area of the container in order to increase heat transfer. Passages may undulate back and forth parallel to the face of the container, as shown in
The outside surface of the containers may be configured with any suitable texture and have any suitable indicia, such as for advertising or any other suitable purpose. The indicia may be formed onto the surface of the container, may be applied to the surface of the container (such as with adhesive or painted) or the indicia may be removably applied to the surface so that the indicia may be changed depending on, for example, an event as which the beverage dispenser 100 is used. The container 100 can be translucent or transparent, allowing lights to be shined into or through it, such as, but not limited to, lights from the back or stand side of the container. In one example, the one or more troughs 101, 102 may form the indicia. For example, as can be seen in
Beverage passages/internal heat exchange surfaces formed within the containers may also be configured with different shapes in a manner substantially similar to that described herein with respect to the troughs. In one exemplary embodiment, where the container 100 includes internal heat exchange surfaces, the container may include removable inserts where the inserts include the beverage passages. Each removable insert may have a different configuration of passages so that a design or indicia formed by the passages may be changed by swapping out the removable inserts. Tubes or hoses may be inserted into the container 100, passing through the walls, such that they extend out of the container 100 at one or both ends, allowing beverage to be conducted through the container 100 and being chilled through heat transfer through the walls of said tubes or hoses.
The space under the stand 103 may have a drip tray, to catch any condensation on the beverage dispensing system or dripping/overflow from the troughs or container. The space under the stand may also have additional decorative features intended to produce special effects, including, but not limited to, a fog or mist machine and its water supply, lights, which may be static, multicolored, moving and/or flickering, sound systems, laser light show system, or slide or video projectors, in order to enhance the ambience of the gathering and potentially reinforce any commercial messages associated with the system.
As seen in
For the inlet of the beverage dispensing apparatus, several different systems can be used. The simplest was shown in
In a more decorative example, a cooling fluid, possibly containing decorative elements including, but not limited to, glitter, coloring agents, or UV active fluorescent dyes can reside in a reservoir in the chilling unit or mounted near the container 500, with this cooling fluid being cooled in the chilling unit and recirculated through the container 500. This reservoir can be hidden or exposed depending on the effect desired. In such an embodiment tubes or hoses can be used to circulate a cooled fluid generated by the refrigeration system to a coil 501 or other closed circuit heat transfer system attached to or within the container 500, or surrounding passages within the container for chilling of beverages passing through said passages, or can by means of inlets and outlets in container 500 directly recirculate the fluid in container 500 through the heat exchanger in the refrigeration system keeping said fluid in container 500 cold. As is apparent to one skilled in the art, many variants of cooling system could be used to actively chill the container 500, including, but not limited to, thermoelectric or Peltier effect coolers if silent or ruggedized operation is desirable at some cost in efficiency.
The exemplary embodiments described herein may be provided as beverage dispenser kits. The kits may be provided with multiple containers 100 or 500 each having the same or different configurations (e.g. surface texture, opacity, translucency, transparency, colors, fluid flow passages/troughs, cooling fluids, etc.) such as those described herein. The kits may also be provided with multiple beverage dispensing attachments 200 and/or mouth pieces 300 and other accessories including, but not limited to, the rotisserie device. In alternate embodiments the beverage dispenser kits may include any suitable components. It would also be possible to use any of these embodiments to heat a beverage, by placing container 100 into an oven which heats it to some temperature suitable for the container material, placing them out on display and pouring beverages through them, or by connecting container 500 to a recirculating fluid system which heats fluid instead of cooling it. Parties are more frequently held in “room temperature” environments wherein temperatures are generally in the 62 to 80 F (17 to 27 Celsius) range or, in the case of outdoor parties, in temperatures as high as around 120 F (49 Celsius). In warmer times of year and warmer climates parties tend to both be more frequent and to be more likely to feature “ice cold” beverages wherein the subject invention may be employed.
It should be understood that the foregoing description is only illustrative of the embodiments. It should also be understood that the embodiments disclosed herein may be used individually or in any suitable combination thereof. Various alternatives and modifications can be devised by those skilled in the art without departing from the embodiments. For example the actively cooled version of this invention could embody a largely solid dispensing device with channels through which cooling fluid flows, rather than a largely liquid filled container as described in the detailed embodiments herein. Accordingly, the present embodiments are intended to embrace all such alternatives, modifications and variances.
In one exemplary embodiment, a beverage dispenser is provided. The beverage dispenser includes: at least one hollow container configured to hold a cooling fluid, the container having at least one heat transfer surface, a first end and a second end; at least one fluid passage in communication with the at least one heat transfer surface, the fluid passage being configured to carry fluid from the first end of the container to the second end of the container, wherein the fluid carried by the at least one fluid passage is cooled as it is carried by the fluid passage; and a stand configured to support the heat transfer surface at an angle for effecting fluid flow as the fluid is carried by the at least one fluid passage.
