Description:
[0001]    This application is a Continuation-In-Part application of Ser. No. 09/089,283, filed Jun. 2, 1998.  
     
    
     
       BACKGROUND OF THE INVENTION  
         [0002]    This invention pertains to methods and apparatuses for chilling beverages, and more specifically to methods and apparatuses for freezing substances into useful forms such that the freezable substances, once frozen, have an elongated, narrow form such that they are insertable into a beverage container, beverage can, juice can, water bottle, sports bottle or the like and can more effectively cool the entire depth of the beverage.  
         DESCRIPTION OF THE RELATED ART  
         [0003]    Basic “cube-shaped” ice “cubes” and ice cube trays are known in the prior art. Typically, ice cube trays are designed to produce ice cubes having a cubic or rectangular form. The prior art also teaches ice cube trays which produce ice cubes having a variety of forms. For example, in U.S. Pat. No. 4,417,716 an ice tray is disclosed which forms completely enclosed chambers of different shaped ice. Further, in Des. 287,856 another shaped ice cube tray is disclosed. Other designs are disclosed in U.S. Des. Pat. Nos. D244,275; D292,802; and D318,281.  
           [0004]    Notwithstanding the fact that the prior art teaches both ice cubes having a variety of forms and the ice cube trays for making these ice cubes, the prior art does not teach a frozen substance or a method of freezing a substance such that the freezable substance, once frozen, has an elongated form such that the frozen substance is insertable into a beverage container, beverage can, juice can, water bottle, sports bottle or the like and resultingly more effectively cools the entire depth of the beverage.  
           [0005]    For example, a conventional beverage can has a depth of about 5.0 inches (127 mm) and has an opening with a width of about 0.75 inches (19.05 mm). Beverage containers such as water, soda or beverage bottles have various depths ranging from about 11.0 inches (279.4 mm) for a typical polyester two liter bottle to about 6.0 inches (152.4 mm) for a typical bottled water bottle. These containers also have openings of various widths. Neither the conventional cubic or rectangular ice cubes, nor the various forms of ice cubes that the prior art teaches, are insertable within these containers because of the narrowness of the containers&#39; openings. Consequently these beverages can not be easily cooled in their containers by the addition of ice cubes or other frozen substances. The only way to cool these beverages while they are in their containers is to place them into a cool environment such as a refrigerator, freezer, ice box, ice bucket, cooler, tub of ice, or the like. However, the introduction of a beverage container into a very cold environment can lead to a messy result as the beverage container may rupture as the freezable substance within the container expands during freezing.  
           [0006]    Furthermore, when a straw is used to consume a beverage, the use of conventional ice cubes in the beverage does not achieve the advantages offered by the current invention. It is common knowledge that when ice is added to a beverage, the ice floats. Consequently, the upper, rather than the lower, portion of the beverage is cooled. When a straw is used to consume the beverage, the non-cooled lower portion of the beverage is sucked up through the straw and introduced into the consumer&#39;s mouth rather than the cooled upper portion of the beverage wherein the ice cubes reside. This is dissatisfying and contrary to the motives behind adding ice cubes to beverage containers; namely, consuming a cool beverage. The current invention solves this problem. The elongated form of the current invention assures that the frozen substance is narrow and insertable into a beverage container, beverage can, juice can, water bottle, sports bottle or the like and that the lower portion of the beverage, from which the beverage is consumed when the consumer uses a straw, is cooled.  
         SUMMARY OF THE INVENTION  
         [0007]    According to one aspect of the invention, a body is provided which has at least one elongated cavity within it. The cavity has a top, a bottom and sidewalls between the top and bottom. The freezable substance is placed into the cavity through the top or bottom. The top and/or bottom have a maximum width, Wm, which is less than or equal to 0.875 inches (22.23 mm).  
           [0008]    According to another aspect of the invention, a body is provided which has at least one elongated cavity within it. The cavity has a top, a bottom and sidewalls between the top and bottom. The freezable substance is placed into the cavity through the top or bottom. The top and/or bottom have a maximum width, Wm, which is less than or equal to 1.1875 inches (30.1625 mm).  
           [0009]    According to another aspect of the invention the top and/or bottom have a maximum width, Wm, which is less than or equal to 0.625 inches (15.875 mm).  
           [0010]    According to another aspect of the invention the cavity has a depth, X. The depth X of the cavity is measured from the top of the cavity to the bottom of the cavity, or vice versa. The depth X is greater than or equal to 1.5 inches (38.1 mm).  
           [0011]    According to another aspect of the invention the top may be circular, having a diameter Dt. The bottom may also be circular, having a diameter Db, where Db is less than or equal to Dt.  
           [0012]    According to another aspect of the invention the width of the cavity is less than or equal to 0.875 inches (22.23 mm) at any point along its depth.

     DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0027]    Referring now to the drawings wherein the showings are for purposes of illustrating a preferred embodiment of the invention only and not for purposes of limiting the same, FIGS. 1, 2 and  3  show the preferred embodiment of the invention. Throughout this specification, the term “ice cube” and “ice cube tray” will be used for convenience of the reader, even though the shape and form of the ice formed by the inventive structure may not be cubic. In addition, while the invention will be referred to in the context of freezing water to form ice, any freezable substance is within the scope of the invention.  
         [0028]    In the preferred embodiment, a body  12  of an article  10  contains multiple cavities  14 . Each cavity  14  has an open top  16  and open bottom  18  and side walls  20  between the top  16  and bottom  18 . The top  16  and/or bottom  18  of each cavity  14  has a maximum width Wm of less than or equal to 0.625 inches (15.875 mm). Each cavity  14  has a depth X of greater than or equal to 1.5 inches (38.1 mm). The depth X is measured from the top  16  to the bottom  18 , as shown in the FIG. 1.  
         [0029]    The maximum width Wm is important, as the primary goal of the invention is to cool drinks within their respective containers. Because most of the drink containers presently have interior diameters less than 0.625 inches (15.875 mm), the present invention provides a way to effectively cool the beverage within its original container. Further, because the ice cube is now “narrow”, and because cooling is a function of surface area, the length of the ice cube is necessarily lengthened in order to provide the requisite level of cooling. Therefore, in an ice cube formed by the inventive article, the depth X is greater than a conventional ice cube. Also because of the greater surface area afforded, the preferred form of the cavity is one that will provide a generally cylindrical shaped ice cube. However, it is within the scope of this invention to have ice cubes having shapes not generally cylindrical.  
         [0030]    [0030]FIG. 4 shows a side view of a cavity  14  wherein the freezable substance is formed as it freezes. The top  16  may be circular having a diameter Dt. The bottom  18  may be circular having a diameter Db.  
         [0031]    In addition to the foregoing, FIG. 1 also shows another embodiment wherein a sealing means  24  is used to prevent the freezable substance from spilling out of the cavity  14  prior to freezing. The sealing means  24  may comprise any type of sealing that does not allow the freezable substance from exiting the cavity  14  prior to its freezing. Typically, the sealing means comprises a cap  25  that may be attached to the body  12 . The sealing means may also be a screw-type of arrangement whereby the sealing means comprises a threaded attachment to either the top  16  or bottom  18  of the body  12 .  
         [0032]    In addition to the foregoing another embodiment is contemplated wherein the maximum width Wm of the top  16  and/or bottom  18  is less than or equal to 0.625 inches (15.875 mm).  
         [0033]    In addition to the foregoing another embodiment is contemplated wherein the cavity has a width less than or equal to 0.875 inches (22.23 mm) at any point along its depth, which is typically less than soda bottles. However, for drinks typically having a wider cavity or “mouth”, the width is less than or equal to 1.1875 inches (30.1625 mm). These containers are typically found on wider “mouth” sport and/or soda bottles.  
         [0034]    In addition to the foregoing another embodiment is contemplated wherein the cavity has a width less than or equal to 0.625 inches (15.875 mm) at any point along its depth.  
         [0035]    In addition to the foregoing, with reference to FIG. 5, another embodiment is illustrated wherein the diameter of the bottom Db is less than or equal to the diameter of the top Dt.  
         [0036]    In addition to the foregoing, with continued reference to FIG. 5, another embodiment is contemplated wherein the width of the cavity at any point along its depth is less than or equal to the width of the top and greater than or equal to the width of the bottom. Also shown in FIGS. 4 and 5 is another preferred embodiment in which the bottom  18  has a rounded, somewhat spherical surface  80 . It is believed the rounded surface  80  will ease the removal of the ice cube or ice structure  88 .  
         [0037]    With reference to FIG. 6, the method of chilling a beverage within its original container will now be described. In a typical beverage container  90 , the lid  92  is removed, typically by unscrewing the lid  92  from the container  90  via threads  94 , depending upon the beverage used. The frozen ice structure  88  is then inserted into the container  90  so that the longitudinal centerline of the structure  88  is coaxial with the longitudinal centerline of the beverage container  90 . The entire depth of the beverage  96  becomes cooled and chilled by the article  88 .  
         [0038]    With reference to FIG. 7, a tray  50  for freezing water to form the ice cubes mentioned hereinabove is shown. The tray comprises a plurality of body&#39;s  12  having one cavity  14  within the body  12 . The tray also has the sealing means for selectively sealing the top and/or the bottom, so that the freezable substance is not spillable from the cavity  14  prior to the freezable substance becoming frozen. The tray  50  also has attachment means  51  to attach the plurality of body&#39;s  12  to one another thus making the body&#39;s  12  are integral with one another and forming the tray  50 .  
         [0039]    The preferred embodiments have been described. It will be apparent to those skilled in the art that the above methods may incorporate changes and modifications without departing from the general scope of this invention. It is intended to include all such modifications and alterations in so far as they come within the scope of the appended claims or the equivalents thereof.  
         [0040]    Having thus described the invention, it is now claimed:
