REFERENCE TO RELATED APPLICATION 
       [0001]    This application claims the benefit of priority from Application Ser. No. 61/501,903, filed Jun. 28, 2011, the contents of which are incorporated herein by reference. 
     
    
     FIELD OF THE INVENTION 
       [0002]    The invention relates generally to beverage packages and methods of packaging and preparing beverages. More particularly, the invention relates to mixes that are distributed in containers that may be used for preparing and consuming beverages. 
       BACKGROUND OF THE INVENTION 
       [0003]    It is possible to completely prepare some beverages during the manufacturing process such that the beverages are ready to consume. However, other beverages exhibit enhanced characteristics if the ingredients are mixed together proximate to when the beverages will be consumed. 
         [0004]    For example, maintaining the ingredients separate may prevent the ingredients from interacting with each other and thereby spoiling taste and freshness. Another benefit of mixing the ingredients together proximate to when the beverage is to be consumed is that this process enables the ingredients to be mixed together in proportions that are preferred by the person who will be consuming the beverage. 
         [0005]    The ingredients for mixed drinks are generally classified as either alcohol or non-alcohol. These components are typically distributed separately such that the consumer may select one or more alcoholic components for use with one or more non-alcoholic components to prepare the mixed drink. 
         [0006]    Preparing an alcoholic or non-alcoholic mixed drink can be a time-consuming, messy and inconvenient process when a number of containers, ingredients and implements are used. It may also be difficult to accurately mix each of the ingredients such that the mixed drink has a flavor that is typically associated with that particular mixed drink. Additionally, liquid may be easily spilled while being poured, which then requires the spilled liquids to be cleaned up. 
         [0007]    It is customary to serve different types of drinks in glasses having different shapes. For example, glasses used to serve daiquiris are typically shaped differently than glasses used to serve margaritas. As such, it is typically necessary to maintain a stock of glasses that are suited for use in conjunction with a variety of mixed drinks. 
         [0008]    Various products have been developed that include two compartments that maintain the beverage components separate prior to consumption. In certain configurations, the barrier between the two compartments is severed to cause the components to be mixed together. 
         [0009]    Another configuration includes an upper chamber may be discarded so that the consumer may drink out of the lower chamber is discussed in U.S. Pat. Nos. 3,779,372 and 4,634,004. Yet another configuration uses a straw that is inserted into the upper part of the container, such as is discussed in U.S. Pat. Nos. 4,408,690 and 5,772,017. 
         [0010]    Methods of packaging and preparing mixed drinks such as the dual-chambered containers described above suffer a number of drawbacks, such as the fact that the packaging tends to be complex, expensive, and typically not reusable or recyclable. In addition, the consumer&#39;s choice of mixing ingredients is limited by the combinations that are packaged and sold together. 
         [0011]    Additionally, when a dual-chambered container is used, the contents are not guaranteed to mix together adequately when the ingredient in the upper chamber merely falls down into the liquid in the lower chamber. When the upper chamber is not removable, the opening in the top of the container may be too small to add ice cubes or crushed ice, which can contribute substantially to the appeal of the mixed drink. 
         [0012]    Thus, there is a need for a method of packaging and preparing a mixed drink that offers simplicity, low expense, ease of use, a minimum of implements for preparing the drink, and flexibility and appeal to the consumer who wishes to add his or her preferred mixing base, such as liquor or a non-alcoholic beverage.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0034]    An embodiment of the invention is directed to a beverage preparation system that generally includes a beverage container  10 , a beverage mix and a beverage container package  14 , as illustrated in the figures. 
         [0035]    The beverage preparation system thereby enables a variety of beverages to be freshly prepared proximate to when it is desired to consume the beverage. The beverage preparation system also enables the beverages to be served in the beverage container in which the product is distributed. 
         [0036]    The beverage container  10  may take a variety of forms such as the beverage containers illustrated in  FIGS. 1 and 2 . Each of the beverage containers  10  includes a receptacle region in which the beverage mix may be packaged and distributed and in which the beverage prepared from the beverage mix may be consumed. 
         [0037]    An example of one suitable configuration for the beverage container  10  is in the shape of a margarita glass, which is illustrated in  FIG. 1 . Another example of a suitable configuration for the beverage container  10  is in the shape of a cocktail glass, which is illustrated in  FIG. 2 . 
         [0038]    The beverage container  10  may be fabricated from a variety of materials using the concepts of the invention. Examples of two such suitable materials are glass and plastic. While the figures illustrate that the beverage containers  10  are formed from a transparent material, it is possible to fabricate the beverage containers  10  that are not transparent. It is also possible to place designs, logos and/or trademarks on the beverage containers  10 . 
         [0039]    The beverage container  10  may be formed with a volume that is selected based upon a variety of factors. In certain embodiments, when the beverage container  10  is used in conjunction with preparing margaritas, the volume may be about 230 milliliters. In certain embodiments, when the beverage container  10  is used in conjunction with preparing martinis, the volume may be about 180 milliliters. 
         [0040]    To enable the packaging system to be used in conjunction with a variety of different beverage containers, the beverage containers may be formed with a height that is approximately equal. The height of the beverage container may be between about 100 millimeters and about 200 millimeters. In certain embodiments, the height of the beverage container is between about 140 millimeters and about 160 millimeters. 
         [0041]    The beverage containers may also be formed with an upper diameter that is approximately equal. The upper diameter of the beverage container may be between about 50 millimeters and about 150 millimeters. In certain embodiments, the upper diameter of the beverage container is between about 100 millimeters and about 130 millimeters. 
         [0042]    The beverage container  10  may include at least one indicia  18  that indicates the volume of the additional ingredient(s) that are intended to be added to the beverage container  10  when preparing the beverage. Such indicia  18  should be sufficiently visible so that the consumer can readily appreciate the volume of the additional component that should be added to the beverage container  10 . On the other hand, the indicia  18  should be configured to not negatively impact the aesthetic qualities of the beverage container  10 . 
         [0043]    In one such embodiment, the indicia  18  is a line that extends at least partially around the beverage container  10 . In another embodiment, the indicia  18  is the name of the product that is to be added to the beverage container  10 . Depending on the size of the beverage container  10 , the name of the product may be repeated several times around the beverage container  10 . 
         [0044]    In one embodiment, the non-alcoholic portion of the beverage may be packaged in the beverage container  10  and the alcoholic portion of the beverage may be added to the beverage container  10  when it is desired to consume the beverage. 
         [0045]    In another embodiment, where it is desired to prevent the components used in preparing the beverage from mixing together too much such that when the beverage is consumed, the flavors of the components are more readily ascertainable, one of the components may be packaged separately from the other components in the beverage container  10 . 
         [0046]    It is possible for the components that are not distributed mixed in the beverage container  10  to also be packaged in the beverage packing system  14  such that when the beverage packing system  14  is purchased, the consumer has all of the components that are needed to prepare the beverage. Alternatively, the consumer may be expected to separately purchase one of more of the components that are needed to prepare the beverage. 
         [0047]    In certain embodiments where the alcohol is intended to be used in preparing the beverage, the beverage container  10  may include a plurality of indicia at different heights that may be used to prepare alcoholic beverages having differing concentrations of alcohol. 
         [0048]    An upper edge  19  of the beverage container  10  may have a variety of shapes using the concepts of the invention. However, an upper surface of the upper edge may be generally planar to facilitate attaching a sealing lid  20 , which is illustrated in  FIG. 3 , to the beverage container  10 . 
         [0049]    The sealing lid  20  may be fabricated from a variety of materials using the concepts of the invention. In one such configuration, the sealing lid  20  is fabricated from a plastic or foil-backed material. A tab  22  may extend from an edge of the sealing lid  20 . The tab  22  may be used to assist with removing the sealing lid  20  from the beverage container  10 , such as is illustrated in  FIG. 4 . 
         [0050]    The sealing lid  20  may be attached to the upper surface of the beverage container  10  during the manufacturing process. The sealing lid  20  should resist separation from the beverage container  10  until the consumer decides to remove the sealing lid  20  so that the beverage mix does not leak. 
         [0051]    It is also possible to fabricate the seal between the sealing lid  20  and the beverage container  10  to be tamper-evident such that consumers can be assured of the purity of the beverage mix. A variety of techniques may be used to create the tamper-evident seal. 
         [0052]    One suitable technique for attaching the sealing lid  20  to the beverage container  10  is an adhesive. Another technique that may be used to attach the sealing lid  20  to the beverage container  10  is a thread mechanism that includes mating thread surfaces on the sealing lid  20  and the beverage container. 
         [0053]    The invention also includes a beverage container package  14  that enables a plurality of the beverage containers  10  to be marketed as a unit. The beverage container package  14  thereby enhances the ability to handle the multiple beverage containers  10  to thereby reduce the potential of the beverage containers being broken or the beverage mix being spilled. 
         [0054]    In certain embodiments, the beverage container package  14  is suited for use in conjunction with the beverage container  10  that is conventionally referred to as a margarita glass, which is illustrated in  FIG. 5 . The beverage container package  14  only covers a portion of each of the beverage container  10 , as illustrated in  FIG. 6 . 
         [0055]    In this configuration, the beverage container package  14  includes a top panel  50 , a bottom panel  52  and a pair of side panels  54  positioned on at least two sides of the top panel  50  and the bottom panel  52  to thereby interconnect the top panel  50  and the bottom panel  52 . 
         [0056]    The top panel  50  may be substantially continuous, as illustrated in  FIG. 6 . The top panel  50  thereby enables sets of the beverage containers to be stacked on top of each other such as for display in a retail store or storage after purchase. 
         [0057]    The bottom panel  52  includes a plurality of apertures  60 . Each of the apertures  60  has a diameter that is smaller than a maximum diameter of the beverage container  10 . The diameter of each of the apertures  60  may also be greater than a diameter of a base portion of the beverage container  10 . 
         [0058]    The beverage container package  14  should have sufficient rigidity to resist bending when the device is lifted. The beverage container package  14  should also have sufficient structural integrity so that the top panel  50  resists breakage when multiple beverage container packages  14  are stacked upon each other. 
         [0059]    The beverage container package  14  may be formed from a sheet of material that is folded to define the top panel  50 , the bottom panel  52  and the side panels  54 . In other embodiments at least one of the top panel  50 , the bottom panel  52  and the side panels  54  are formed separately and then attached to each other to fabricate the beverage container package  14 . 
         [0060]    A variety of materials may be used to fabricate the beverage container package  14  depending upon factors such as the shape and size of the beverage containers  10 . In one such configuration, cardboard is used to fabricate the beverage container package  14 . The cardboard may be fabricated with or without corrugations. 
         [0061]    In another configuration of the beverage container package  114  that is suited for use in conjunction with the beverage container  110  that is conventionally referred to as a cocktail glass and which is illustrated in  FIG. 7 , the beverage container package  114  includes a top panel  150 , a bottom panel  152  and a pair of side panels  154  positioned on at least two sides of the top panel  150  and the bottom panel  152  to thereby interconnect the top panel  150  and the bottom panel  152 , as illustrated in  FIG. 8 . 
         [0062]    The configuration of the beverage container package  114  may also include an intermediate panel  60  that is positioned between the top panel  150  and the bottom panel  152  and which extends between the side panels  154 . While not illustrated, the intermediate panel  160  includes a plurality of apertures that are similar to the apertures  60  formed in the beverage container package  14  illustrated in  FIG. 6 . 
         [0063]    The side panels  154  may be formed with a height that is greater than a height of the beverage container  110  and the intermediate panel  160  may be positioned to support the lower surface of the beverage container  110  above lower edges of the side panels  154  and above the bottom panel  152 . This configuration positions the upper surface of the beverage container  110  below upper edges of the side panels  154  and below the top panel  150 . 
         [0064]    Using this configuration minimizes that forces placed on the beverage container package  114  during the stacking process will be transferred to the beverage containers  110  that are stored in the beverage container package  114  to thereby reduce the potential of the beverage containers  110  being damaged during the shipping and distribution process. 
         [0065]    In other embodiments, the lower surface of the beverage container  110  is in contact with the bottom panel  152  and the upper surface of the beverage container  110  is in contact with the top panel  150 . Using this configuration, the beverage container and the beverage container package  114  contribute to support when the packages are placed in a stacked configuration. 
         [0066]    This configuration of the beverage container package  114  substantially encloses a plurality of beverage containers  110 . While it is illustrated that opposite ends of the beverage container package  114  are open, it is possible to include end panels on the beverage container package  114 . 
         [0067]    To enhance the ability to carry the beverage container package  114 , at least one handle  170  is provided on the beverage container package  114 . The at least one handle  170  may be cut from the same material that is used to fabricate the other portions of the beverage container package  114 . 
         [0068]    The at least one handle  170  may be positioned in a retracted position, which is illustrated in  FIG. 8 . When in the retracted position, the at least one handle  170  may be substantially aligned with the outer surface of the beverage container package  114 . 
         [0069]    The at least one handle  170  may be moved to the extended position, which is illustrated in  FIG. 9 . When the at least one handle  170  is in the extended position, an opening  172  is provided through which a person can extend a portion of his/her hand to grasp the handle  170 . 
         [0070]    In another configuration of the beverage container package  214  that is suited for use in conjunction with the beverage container  210  that is conventionally referred to as a pint glass and which is illustrated in  FIG. 10 , the beverage container package  214  includes a top panel  250 , a bottom panel  252  and a pair of side panels  254  positioned on at least two sides of the top panel  250  and the bottom panel  252  to thereby interconnect the top panel  250  and the bottom panel  252 , as illustrated in  FIG. 11 . 
         [0071]    This configuration of the beverage container package  214  is particularly suited for use in conjunction with the beverage container  10  having the shape of a beverage container having a generally cylindrical shape or a generally cylindrical but tapered shape where a diameter of the upper end is larger than a diameter at the lower end. 
         [0072]    The configuration of the beverage container package  214  may also include an intermediate panel  260  that is positioned between the top panel  250  and the bottom panel  252  and which extends between the side panels  254 . 
         [0073]    The intermediate panel  260  includes a plurality of apertures  270  that are similar to the apertures  60  formed in the beverage container package  14  illustrated in  FIG. 6 . In particular, the apertures  270  have a shape and size that generally conforms to a shape and size of the beverage container  210  proximate to where the intermediate panel  260  is positioned. 
         [0074]    This configuration of the beverage container package  214  substantially encloses a plurality of beverage containers  210 . While it is illustrated that opposite ends of the beverage container package  214  are open, it is possible to include end panels on the beverage container package  214 . 
         [0075]    To enhance the ability to carry the beverage container package  14 , at least one aperture  280  may be provided in the beverage container package  214 . While it is illustrated that the at least one aperture  280  is formed in the top panel  250 , it is possible for the at least one aperture  280  to be formed in the bottom panel  252  or the side panels  254 . 
         [0076]    The at least one aperture  280  may have a diameter that is sufficiently large so that a person can extend his/her finger into the aperture  280  when it is desired to lift the beverage container package  214 . 
         [0077]    Another configuration of the beverage container package  314  is illustrated in  FIG. 12 . This configuration is similar to the beverage container package  214  illustrated in  FIG. 11  except that instead of the beverage containers  210  being placed in two rows that are adjacent to each other, the beverage containers  310  are placed into two rows that are stacked upon each other. 
         [0078]    The packaging system may include at least one cutout  316  on a surface thereof. In certain embodiments, at least one of the side panels  354  or the top panel  350  may include the at least one cutout  316  to enable potential customers to see the color of the beverage packaged in the beverage container  310 . 
         [0079]    The at least one cutout  316  can be formed with a shape that generally conforms to the shape of the beverage container  310  to enhance the ability to view the contents of the beverage container  310 . In certain embodiments, at least one of a height and a width of the at least one cutout  316  are less than the height and the width of the beverage container  310 . The at least one cutout should be formed with a height and a width and be positioned on the beverage container  310  so not as to negatively impact the structural integrity of the beverage container  310 . 
         [0080]    A method of packaging a mixed drink according to the present invention thus includes pre-packaging a flavorful and/or colorful, pre-measured ingredient or mixture of ingredients into a beverage container that is marketed and sold with extra head-space for the consumer to add alcohol, ice or other ingredients if desired. The beverage container is even suitable for use as a drinking vessel. 
         [0081]    The invention therefore provides a method of packaging the ingredients that are desired for a mixed drink, to which ice may be added. Alternatively, the method of packaging provides all the ingredients for making a mixed drink recipe except for alcohol, which may be added as desired by the preparer or consumer. 
         [0082]    The package may be marked and/or labeled to indicate that additional ingredients may be added to the contents, such as ice or alcohol, and optionally some other beverage and/or garnish, to customize the drink according to the consumer&#39;s taste. 
         [0083]    Because the mixture can be combined and consumed, the number of containers and implements that are needed to make the mixed drink is substantially reduced, thus minimizing the time, effort and inconvenience that are associated with prior art methods of packaging the ingredients for mixed beverages. The ease and enjoyment of selecting, preparing, serving and consuming a mixed drink that is packaged according to the inventive method are thereby enhanced. 
         [0084]    When it is desired to consume the beverage, the partially filled beverage container  10  is opened by removing the sealing lid  20 . Whatever additional components desired by the consumer are then added to the beverage container  10  and the components are mixed together to provide the finished beverage. The consumer may drink directly out of the beverage container  10 . 
         [0085]    The invention thereby eliminates the need for separate implements to be used for measuring the components used in preparing the beverage. Thus, the process of preparing the beverage is greatly simplified, because the storage, transport, set-up and clean-up of additional ingredients, containers and implements are virtually eliminated. 
         [0086]    Examples of beverages that may be prepared using the invention include Long Island ice tea, cosmopolitan, strawberry daiquiri, mojito, appletini, classic margarita, whiskey sour, blood orange martini, peach bellini and pina colada. 
         [0087]    Depending on the beverage that is desired to be prepared, different ingredients may be used to prepare the beverage mix. For example, when the beverage mix is intended to be used in preparing margaritas, the beverage mix may include water, at least one sweetener and at least one flavoring agent. 
         [0088]    A variety of compositions may be used for the at least one sweetener. The compositions may be naturally or artificially derived. An example of compositions that may be used as the at least one sweetener include sugar and aspartame. 
         [0089]    A variety of compositions may be used for the at least one flavoring agent. The compositions may be naturally or artificially derived. An example of compositions that may be used as the at least one flavoring agent include citric acid and lemon juice concentrates. 
         [0090]    The beverage mix may also include at least one coloring agent. The coloring agent may be naturally derived or artificially derived. An example of one such suitable coloring agent is FD&amp;C blue #1. 
         [0091]    Depending on the ingredients used in fabricating the beverage mix and the anticipated length of time between when the beverage mix is prepared and consumed, it may be desirable to add at least one preservative to the beverage mix. Examples of suitable preservatives include sodium benzoate and potassium sorbate. 
         [0092]    Depending on the type of beverage being prepared, it is possible for additional ingredients to be added to the beverage container prior to the beverage being consumed. Examples of the additional ingredients include ice cubes/chips, olives and slices of fruit. 
         [0093]    Such additional ingredients may be distributed with the invention. For example, in certain embodiments, a container of olives is distributed with the product. The container of olives may be sufficiently large so that the container contains at least one olive that may be placed in each of the beverage container. However, the container may be sufficiently small so that an excess amount of olives is not included in the package. 
         [0094]    An example of another product that may be distributed with the invention is ground salt or sugar that is intended to be placed on the rim of the glass when the beverage is prepared for consumption. 
         [0095]    The invention may also include at least one additional container (not shown) of alcohol that may be used in conjunction with the beverage mix contained in the beverage container  10  when preparing the beverage. In certain embodiments, the at least one additional container attached to the beverage container package. In other embodiments, the at least one additional container is placed adjacent to or proximate
