DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
For the purposes of illustration only, and not to limit the generality, the present invention will now be described in detail with reference to the accompanying figures. This invention is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced or being carried out in various ways. Also the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. The use of “including,” “comprising,” “having,” “containing” “involving,” and variations thereof herein, is meant to encompass the items listed thereafter and equivalents thereof as well as additional items.
Referring to the drawings, and more particularly to FIG. 1, there is generally indicated at 10 a single serve or individual frozen drink dispenser. The dispenser 10 includes a housing 12 with a forwardly protruding bottom shelf 14 arranged to support a blender cup 16 for the dispensed frozen beverage. A blender drive 18 is provided on the bottom shelf 14 to drive the operation of blades 20 provided in the blender cup 16. The housing 12 further includes a dispensing chamber 22 positioned above the bottom shelf 14. The housing 12 further includes a water reservoir 24 positioned at the rear of the housing and an electronic control panel 26 provided on a front surface 28 of the housing to control the operation of the dispenser 10.
Referring to FIG. 2, the dispensing chamber 22 includes a cartridge receptacle 30 and a door 32 that provides access to the cartridge receptacle. The cartridge receptacle 30 is configured and dimensioned to receive a disposable, frozen beverage cartridge 34 (not shown in FIG. 2). The frozen beverage cartridge 34 will be shown and described with reference to FIGS. 3-5. The dispensing chamber 22 further includes a dispense plunger 36 that is controlled by the electronic control panel 26. The dispense plunger 36 drives the downward movement of ingredients contained within the frozen beverage cartridge 34 through a mesh or serrated disc 38 to separate the frozen ingredients being pushed through the disc. The mesh disc 38 may be fabricated from stainless steel material, or any other suitable material, that is capable of separating the frozen material. In an alternative embodiment, the serrated disc could be embedded within a serrated platform under the product to allow more efficient and timely blending.
In some embodiments, the frozen beverage cartridge 34 includes an impermeable container fabricated from cardboard or plastic material to contain frozen edible ingredients. In one embodiment, the frozen beverage cartridge 34 is cylindrical in shape. However, other suitable shapes that correspond to the shape of the dispense plunger 36. The frozen beverage cartridge 34 contains ingredients in liquid or non-frozen condition that are placed in a freezer for cooling. As used herein, a “cartridge” may take any suitable form depending on the size and form factor of the dispenser 10. The frozen beverage cartridge 34 may be impervious to air and/or liquid. The frozen beverage cartridge 34 may include edible frozen ingredients, such as fruit, milk, a drink mix, and/or any other suitable ingredient for creating a frozen beverage, such as a smoothie or the like. In preparing a frozen drink, such as a smoothie, the process of preparing a beverage may include infusion, mixing, dissolving or otherwise forming a drinkable substance using water or other beverage precursor (e.g., flavored or otherwise treated water, or other liquid) with the edible ingredient contained within the frozen beverage cartridge. Also, reference to “water” herein is to any suitable water formulation, e.g., filtered, de-ionized, softened, etc., as well as any other suitable precursor liquid used to form a frozen beverage, such as sweetened or flavored water, milk, etc.
Referring to FIGS. 3-5, the dispensing chamber 22, in addition to the dispense plunger 36, includes a cover 40 that is disposed over the dispense plunger to prevent the ingredients from exiting up through the frozen beverage cartridge 34 as the dispense plunger moves downward through the frozen beverage cartridge. The cover 40 assists in maintaining the cartridge receptacle 30 in a sanitized condition while operating the dispense plunger 36. The dispensing chamber 22 further includes a water inlet 42 for introducing measured pumped water into the dispense plunger 36 from the water reservoir 24. Thus, the water is introduced into the blender cup 16 via the dispense plunger 36. The water is used to prepare the frozen beverage and to rinse the dispense plunger 36 and the disc 38.
Referring to FIG. 3, the dispense plunger 36 is shown in a pre-dispense or upper position. In this position, the frozen beverage cartridge 34 may be inserted into the cartridge receptacle 30 with the dispense plunger and the cover 40 disposed above the frozen beverage cartridge.
Referring to FIG. 4, the dispense plunger 36 is shown in a dispense or substantially lower position. In this position, the dispense plunger 36 is moved into the frozen beverage cartridge 34 to push the ingredients contained within the frozen beverage cartridge through the disc 38 and into the blender cup 16.
Referring to FIG. 5, the dispense plunger 36 is further shown in the dispense position with water or another suitable fluid being dispensed through the dispense plunger from the water inlet 42 through the disc 38 and into the blender cup 16. Once the blender cup 16 is filled with the edible ingredients and water, the blender drive 18 is operated to rotate the blades 20 provided in the blender cup. This operation mixes the ingredients within the blender cup 16 to create the finished drink, e.g., the smoothie. As shown, a bottom edge 44 of the dispensing chamber 22 and a bottom surface 46 of the disc 38 are closely proximate to a top edge 48 of the blender cup 16 to prevent the ingredients and water from splashing out of the blender cup.
FIG. 6 illustrates other components of the dispenser 10. As shown, the water reservoir 24 is connected to a water pump 50, which drives the movement of the water from the water reservoir to the dispense plunger 36. The dispenser 10 further includes an electronic control box or controller 52 that is coupled to the water pump 50, the blender drive 18, and to the electronic control panel 26. The electronic control box 52 is further coupled to a drive motor 54 to drive the up-and-down movement of the dispense plunger 36, and to the blender drive 18 to rotate the blades 20 of the blender cup. The electronic control box 52, via the electronic control panel 26, controls the operation of these component parts of the dispenser 10.
In light of the foregoing, it will now be understood that the dispenser 10 of the present disclosure is capable of preparing an individual frozen drink from a disposable frozen beverage cartridge 34 containing the necessary ingredients for preparing the frozen drink. In operation, the door 32 of the dispensing chamber 22 is opened and a new frozen cartridge 34 is inserted into the cartridge receptacle 30. Once inserted, the door 32 is closed and the dispense plunger 36 is driven downwardly to expel the frozen ingredients from the frozen beverage cartridge 34 through the disc 38 and into the blender cup 16. Once fully expelled, a pre-measured amount of water is delivered to the blender cup 16 from the water reservoir 24 by operating the water pump 50. This part of the process also rinses the dispense plunger 36 and the disc 38 so as to maintain a clean environment. Once the frozen ingredients and the water are disposed in the blender cup 16, the blender drive 18 is operated to rotate the blades 20. This action blends or mixes the frozen ingredients and the water to create the frozen drink that is suitable for consumption. Once the frozen drink is prepared, the door 32 to the dispensing chamber 22 may be opened to remove the depleted cartridge 34. At this point the process of preparing another frozen beverage may begin again.
A method of dispensing a frozen drink can be achieved by using the dispenser 10 of embodiments of the present disclosure. For example, the method may include inserting a frozen beverage cartridge 34 into the cartridge receptacle 30 of the individual frozen drink dispenser 10. Next, the contents of the frozen beverage cartridge 34 are pushed through the meshed or serrated disc 38 positioned at a bottom of the cartridge receptacle 30. Next, the contents of the frozen beverage cartridge 34 are dispensed from the meshed or serrated disc 38 into the blender cup 16. Next, the contents of the frozen beverage cartridge dispensed in the blender cup 16 are blended with blades 20 provided in the blender cup. Optionally, when pushing the contents of the frozen beverage cartridge 34 through the meshed or serrated disc 38, the method further may include injecting fluid from the water reservoir 24 into the cartridge receptacle 30 when pushing contents of the frozen cartridge to add flavor, for example, to the contents being pushed through the meshed or serrated disc.
Having thus described at least one embodiment of the present disclosure, various alternations, modifications and improvements will readily occur to those skilled in the art. Such alterations, modifications and improvements are intended to be within the scope and spirit of the disclosure. Accordingly, the foregoing description is by way of example only and is not intended to be limiting. The disclosure's limit is defined only in the following claims and equivalents thereto.
