PATENT DESCRIPTION
INCORPORATION BY REFERENCE TO ANY PRIORITY APPLICATIONS 
       [0001]    Any and all applications for which a foreign or domestic priority claim is identified in the Application Data Sheet as filed with the present application are hereby incorporated by reference herein and made a part of the present disclosure. 
       BACKGROUND 
       [0002]    Field 
         [0003]    The present disclosure relates to containers and, more particularly, to containers that are rotatable or spinnable without tipping that would cause the container&#39;s contents to spill. 
         [0004]    Description of Related Art 
         [0005]    Beverage containers currently exist that have uneven bases. Such containers can be made to wobble. However, the range of velocity that such containers can experience is quite limited because too much movement, too much speed, or both will cause these beverage containers to spill their contents. Others have attempted to mitigate the spilling problem with caps, braces, and heavier materials. However, these approaches do not provide an easily rotatable, elegant, and versatile container that is resistant to tipping or spilling. 
         [0006]    Accordingly, what is needed are containers that can be rotated without concern for tipping or excessive wobbling of the container that may cause the contents of the container to spill or that at least provide the public with a useful choice. 
       SUMMARY OF THE INVENTION 
       [0007]    In some configurations, a glass configured for stable spinning includes a base and a container wall extending upwardly from the base. The base and the container wall cooperate to define a central axis and a receptacle for receiving a liquid. A bottom surface of the base comprises a central axis feature positioned about a central axis of the glass and a lateral feature positioned proximate an outer edge of the bottom surface of the base a radial distance from the central axis. The lateral feature encircles the base. The central axis feature extends below a plane defined by the lateral feature by an offset distance such that the glass rests on the central axis feature when placed on a flat surface and the lateral feature contacts the flat surface when the glass is tilted. The offset distance is between 0.05 mm and 0.15 mm and a ratio of the radial distance to the lateral feature to the offset distance is between 200:1 and 1000:1. 
         [0008]    In some configurations, an interior surface of the container wall comprises at least one aeration feature that extends in a circumferential direction of the container wall. 
         [0009]    In some configurations, the at least one aeration feature comprises a first aeration feature and a second aeration feature. 
         [0010]    In some configurations, a first plane defined by the first aeration feature is angled relative to a second plane defined by the second aeration feature. 
         [0011]    In some configurations, both the first plane and the second plane are angled relative to an upper edge of the container wall. 
         [0012]    In some configurations, the at least one aeration feature extends uninterrupted around the container wall. 
         [0013]    In some configurations, the base is circular or polygonal in shape. 
         [0014]    In some configurations, a glass configured for stable spinning includes a base and a container wall extending upwardly from the base. The base and the container wall cooperate to define a central axis and a receptacle for receiving a liquid. A bottom surface of the base comprises a central axis feature positioned about a central axis of the glass and a lateral feature positioned proximate an outer edge of the bottom surface of the base a radial distance from the central axis. The lateral feature encircles the base. The central axis feature extends below a plane defined by the lateral feature by an offset distance such that the glass rests on the central axis feature when placed on a flat surface and the lateral feature contacts the flat surface when the glass is tilted. A portion of the central axis feature that intersects the plane of the lateral feature defines a projection diameter, wherein a ratio of a diameter of the lateral feature to the projection diameter is between 10:1 and 40:1. 
         [0015]    In some configurations, an interior surface of the container wall comprises at least one aeration feature that extends in a circumferential direction of the container wall. 
         [0016]    In some configurations, the at least one aeration feature comprises a first aeration feature and a second aeration feature. 
         [0017]    In some configurations, a first plane defined by the first aeration feature is angled relative to a second plane defined by the second aeration feature. 
         [0018]    In some configurations, both the first plane and the second plane are angled relative to an upper edge of the container wall. 
         [0019]    In some configurations, the projection diameter is between 3 mm and 5 mm. 
         [0020]    In some configurations, the base is circular or polygonal in shape.

     DETAILED DESCRIPTION 
       [0046]    In the following description, for purposes of explanation, specific details are set forth in order to provide an understanding of embodiments of the invention. It will be apparent, however, to one skilled in the art that the invention can be practiced without these details. Furthermore, one skilled in the art will recognize that embodiments of the present invention, described below, may be implemented in a variety of ways.

Also, the appearances of the above noted phrases in various places in the specification are not necessarily all referring to the same embodiment or embodiments. 
         [0048]    The use of certain terms in various places in the specification is for illustration and should not be construed as limiting. The terms “include,” “including,” “comprise,” and “comprising” shall be understood to be open terms, and in any lists, the listed items are examples and are not meant to be limiting to only the listed items. Any headings used herein are for organizational purposes only and shall not be used to limit the scope of the description or the claims. 
       A. General Overview 
       [0049]    Presented herein are embodiments of a container that does not topple, without excessive force, despite being designed to rotate about a central axis. In embodiments, the container may be made any material, including but not limited to plastic, glass, wood, metal, and the like, and may accommodate variety of payload in the receptacle of the container, including but not limited to liquids and solids. 
         [0050]    In embodiments, prevention of tipping may be achieved by the container having a ratio of a base radius to its central axis height being within a range of approximately 1:2 to 1:5. In some embodiments, the value of ratio of distances between centers of the central axis feature and a lateral feature to the difference between their heights being within a range of approximately 50:1 to 1000:1, approximately 200:1 to 1000:1 or approximately 275:1. In some embodiments, the ratio of the base&#39;s lower surface area and a projection area of the central axis feature being within a range of approximately 200:1 to 800:1, approximately 400:1 to 750:1, or approximately 395:1. It shall be noted that, while the above-identified ratios work well m producing a container that is stable when rotated, one skilled in the art shall recognize that numerous other ratios may be used to similar effect. It shall also be noted that the central axis feature, lateral feature(s), and the container may be shaped in almost any way and constructed using almost any material. 
       B. Exemplary Embodiments 
       [0051]    Presented herein are some embodiments provided by way of example only and not by way of limitation. One skilled in the art shall recognize other embodiments, which fall within the spirit and scope of the present patent document, may also be made. 
         [0052]      FIG. 1A  (“ FIG. 1A ”) depicts a perspective view of a container according to embodiments of the present invention.  FIG. 1B  depicts the base view of the container of  FIG. 1A  according to embodiments of the present invention. 
         [0053]    As shown in  FIGS. 1A and 1B , the container  100  comprises a receptacle portion  105  for receiving a payload, such a liquid or solid, and a base  110 . In embodiments, the container has a central axis  115  about which it can rotate. 
         [0054]    Turning now to  FIG. 2  depicts a section view  200  and a side view  250  of the container of  FIG. 1A  according to embodiments of the present invention. In embodiments, the rotational container comprises a central axis feature on the base (e.g., base rotation area  215 ) upon which the container  200  may easily rotate, and one or more lateral features  240  on the base to provide stability. As shown in the  FIG. 2 , the container  200  includes a hollowed portion, otherwise known as the container storage area  245  or receptacle, sits above and is attached to the base, which comprises the rotation feature  215  and the lateral feature  240 . In embodiments, the central axis feature  215  is a center of balance for the container. 
         [0055]    In embodiments, the container rotates about its central axis  210  on the base rotation feature  215  and is stabilized by the lateral features  240 , as well as by the proportionality and structural quality of these features. In embodiments, the container&#39;s stability when rotating may be achieved by maintaining an appropriate ratio of the base&#39;s radius  225  to the central axis fixture&#39;s height  220  (e.g., a ratio around 1:2 to 1:5) and with a base possessing at least one lateral feature  240  of lesser height (e.g., height  235 ) than the central base rotation feature  215 . It shall be noted that since the lateral feature extends around the base, in a cross-section of the container, it may be thought of as being two lateral features. However, it shall also be noted that there may be additional or different lateral features present at or near the base to provide stability. In such embodiments, the lateral features may be located at equal distances from the central axis feature  215  or may be at different distances. 
         [0056]    In embodiments, the ratio of the surface area between the base rotation area  215  and the overall base (e.g., area calculated using the base radius  225 ) of the container may be around 1:25. 
         [0057]    Furthermore, in embodiments, the height  235  of the central axis feature  215  in relation to the lateral feature  240  may be in the range of 0.05-0.15 mm when the base size (e.g., the base diameter) is within 20-100 mm. 
         [0058]    In embodiments, good rotation is achieved when the container also has appropriately set base and lateral features for the container and an appropriate center of gravity when loaded. Such a container will rotate about the axis using the base rotational feature (e.g., feature  215 ) and using the lateral feature(s) (e.g., feature  240 ) for stability. 
         [0059]    When a container processes these proportions, each of the central axis feature, the lateral feature or features, and the container structure groupings may be different shapes. Furthermore, when these proportions are present, the material or materials of the container may vary; however, the more uniform and solid the material, the more the proportions are likely to be maintained under load. 
         [0060]    Turning now to  FIG. 3A  and  FIG. 3B , depicted is a perspective view and a base view, respectively, of an alternative embodiment of a container  300 . As shown in  FIGS. 3A and 3B , the container  300  comprises a central axis  315  about which it may rotate and a hollowed portion/container storage area  305  that sits above and is attached to a base  310 . As illustrated in  FIG. 4 , the base  310  comprises the base rotation feature  415  and lateral features  445 . Also illustrated in  FIG. 3B  is an approximation of the surface area  320  of the base feature  415  upon which the container rotates when on a supporting surface, and the surface area  325  of the lateral feature  445 , part or all of which may, at times, also contact the supporting surface to provide stability. 
         [0061]      FIG. 4  depicts a section view  400  and a side view  405  of the container of  FIG. 3A  according to embodiments of the present invention. As shown in  FIG. 4 , the lateral feature comprises a wave-like feature that extends from the base rotation area  415 , moves upward to a maximum lateral feature depth  440 , and then extends back downward to a height (i.e., the lateral feature height  435 ) that is still slightly above the base rotation area  415 . This height difference (i.e., the lateral feature height  435 ) allows the container to easily rotate about the central rotation point  415  but still provides stability from the lateral feature. In embodiments, the container may possess the same or similar ratios as previously described. 
         [0062]      FIG. 5  depicts additional section views and side views of embodiments of containers  500  according to embodiments of the present invention. 
         [0063]      FIG. 6  depicts additional perspective views of alternative embodiments of containers  600  according to embodiments of the present invention. 
         [0064]    Turning now to  FIG. 7A , depicted is a perspective view of yet another alternative embodiment of a container according to embodiments of the present invention.  FIG. 7B  depicts the base view of the container of  FIG. 7A  according to embodiments of the present invention. As previously noted, the container may take numerous shapes and sizes provided the base comprises a central rotation point and one or more lateral features for stability. It shall be noted that the shape of a container may be suited for particular purposes. For example, the prior embodiments of  FIG. 3A  may be well suited for serving whiskey; whereas, the shape of the container in  FIG. 7A  may be better suited for serving wines. 
         [0065]    As shown in  FIGS. 7A and 7B , the container  700  comprises a central axis  715  about which it may rotate and a hollowed portion/container storage area  705  that sits above and is attached to a base  710 . 
         [0066]      FIG. 8  depicts a section view  800  and a side view  805  of the container of  FIG. 7A  according to embodiments of the present invention. As shown in  FIG. 7 , the lateral feature  840  comprises a slope feature that extends from the base rotation area  815  to the edge of the container and is slightly above the base rotation area  815 . This height difference (i.e., the lateral feature height  835 ) allows the container to easily rotate about the central rotation point  815  but still provide stability from the lateral feature. In embodiments, the container may possess the same or similar ratios as previously described. 
         [0067]      FIG. 9A  depicts a perspective view of yet another alternative embodiment of a container according to embodiments of the present invention, and  FIG. 9B  depicts the base view of the container of  FIG. 9A  according to embodiments of the present invention. 
         [0068]      FIG. 10  depicts a section view  1000  and a side view  1005  of the container of  FIG. 9A  according to embodiments of the present invention. As shown in  FIG. 10 , the lateral feature  1045  comprises a wave-like feature similar to that depicted and described above with respect to  FIG. 4 . 
         [0069]      FIG. 11  depicts additional section views and side views of embodiments of containers  1100  according to embodiments of the present invention. 
         [0070]      FIG. 12  depicts additional perspective views of alternative embodiments of containers  1200  according to embodiments of the present invention. 
         [0071]    It shall be reiterated that the containers may take a variety of shapes and sizes, including that the base may vary from the container receptacle portion. Consider, for example, the embodiments shown in  FIGS. 13A-16 . 
         [0072]      FIG. 13A  depicts a perspective view of an octagonal-based container  1300  according to embodiments of the present invention.  FIG. 13B  depicts the base view of the octagonal-based container of  FIG. 13A  according to embodiments of the present invention. 
         [0073]      FIG. 14  depicts a section view  1400  and a side view  1450  of the octagonal-based container of  FIG. 13A  according to embodiments of the present invention. 
         [0074]      FIG. 15  depicts the octagonal-based container  1500  flared out according to embodiments of the present invention. 
         [0075]      FIG. 16  depicts a section view  1600  and a side view  1650  of a pentagonal-based container according to embodiments of the present invention. 
         [0076]    It shall also be noted that rotating the container may be done for a variety of purposes. The container may be spun to help aerate a beverage contained within the container. The container may be spun simply for amusement. And, the container may be incorporated into a game and spun as an indicator or random indicator generator. Consider, for example, the container  1700  depicted in  FIG. 17 . 
         [0077]      FIG. 17  depicts a side view of a container  1700  that includes at least one indicator according to embodiments of the present invention. In embodiments, the indicator may be one or more words, a logo  1710 , a graphic  1715 , or any combination thereof. Thus, the container may be a basis for a game, whereby having a marker or indicator (e.g., logo  1710  and/or graphic  1715 ) at any of the peripheries of the container may be used as an indicator. For example, after rotating, a person or object in front of the marker may indicate the next step or the next player of a game. 
         [0078]      FIGS. 18 and 19  illustrate an additional embodiment of a container or glass  1800  that is configured to stably rotate about a central axis  1810 . The container  1800  can be similar to other containers described herein. Accordingly, features not specifically described with respect to the container  1800  can be assumed to be the same as or similar to corresponding features from other containers described herein, or can be of another suitable arrangement. The container  1800  includes a base  1802  and a container wall  1805  that extends upwardly from the base  1802 . The container wall  1805  is a hollow cylinder that defines a receptacle portion  1845  configured to receive a liquid or other contents. Unless otherwise noted, the term cylinder is used in a broad sense, which includes an extruded closed loop of any shape, such as circular or polygonal, for example. The container wall  1805  can taper along its length such that a cross-sectional dimension (e.g., diameter) of the container wall  1805  varies along its height. 
         [0079]    The container  1800  preferably includes at least one feature  1850  in the container wall  1805 . In the illustrated configuration, the feature  1850  is an aeration feature that facilitates aeration of the contents within the receptacle portion  1845  as a result of spinning the container  1800 . However, in other embodiments, the feature  1850  can be purely decorative and, thus, may be located only on an outer surface of the container  1800 . The illustrated feature  1850  comprises a band that extends uninterrupted in a circumferential direction of the container  1800 . The illustrated band  1850  is an inward curve in the container wall  1805  that defines a concave curvature on an outer surface of the wall and a convex curvature on the inside/interior surface of the container wall  1805  that protrudes inwardly relative to adjacent portions of the container wall  1805 . However, in other configurations, the band  1850  can be positioned on only one of the inner and outer surfaces of the container wall  1805 . 
         [0080]    A plane defined by the band  1850  is angled relative to an upper edge of the container  1800  and/or is non-perpendicular with respect to the central axis  1810 . Thus, the band  1850  provides an appearance of vertical or wave-like movement during spinning of the container  1800 , which can facilitate aeration of the liquid within the receptacle portion  1845 . In the illustrated configuration, the container  1800  includes two aeration features  1850  that define planes that are angled relative to one another. In other configurations, the features  1850  could comprise interrupted bands or more complex shapes that do not define a flat plane. However, in some such configurations, an average plane of such a band can be angled relative to the upper edge of the container  1800  and/or non-perpendicular with respect to the central axis  1810 . Because the illustrated bands  1850  extend in a circumferential direction of the container wall  1805 , aeration can be facilitated while avoiding excess splashing of the liquid, which can occur with features that extend in a vertical direction or in alignment with the central axis  1810 . 
         [0081]      FIG. 19  illustrates an enlarged view of the base  1802 , which can generally be similar to other containers described herein. However, the configuration of  FIG. 19  is notable for the relatively small central axis feature  1815 . The lateral feature  1840  extends uninterrupted about a circumference or perimeter of the base  1802  and is located at or adjacent an edge of the base  1802  to maintain the look of a conventional glass. The lateral feature  1840  can be configured to contact a flat surface upon which the container  1800  rests along a small surface area. Thus, the lateral feature  1840  can be relatively narrow in comparison to an overall diameter of the base  1802 . 
         [0082]    The lateral feature  1840  can define or approximately define an overall diameter  1870  of the base  1802 . A bottom surface of the lateral feature  1840  can also define a plane that extends perpendicular to the central axis  1810 . As described with respect to the other containers herein, the central axis feature  1815  extends below the lateral feature  1840  such that the container  1800  rests on the central axis feature  1815  when placed on a hard, flat surface. As described above, in some configurations, the central axis feature  1815  protrudes beyond the plane of the lateral feature  1840  by a lateral feature height or offset distance  1835  that can be about 0.05 mm to about 0.15 mm for a base diameter  1870  between about 20 mm to about 100 mm. A ratio of the radial distance to the lateral feature to the offset distance can be between about 200:1 and about 1000:1 taking into account manufacturing variations. 
         [0083]    A portion of the central axis feature  1815  that intersects the plane of the lateral feature  1840  defines a projection cross-sectional dimension or projection diameter  1872  that can be a small portion of the overall base diameter  1870 . In some configurations, the projection diameter  1872  can be between about 3 mm and about 5 mm and the base diameter  1870  can be between about 60 mm to about 100 mm, or about 70 mm to about 90 mm, or about 80 mm. In some configurations, a ratio of the base diameter  1870  to the projection diameter  1872  can be about 10:1 to about 40:1. Thus, an area defined by the intersection of the central axis feature  1815  and the plane of the lateral feature  1840  can be small relative to the area defined by the lateral feature  1840  or the area of the base  1802 . In some configurations, the ratio between these areas can be about 1:200 to about 1:1000, about 1:400 to about 1:750, or about 1:500.
