   DETAILED DESCRIPTION 
   The embodiments of the present invention described below are not intended to be exhaustive or to limit the invention to the precise forms disclosed in the following detailed description. Rather, the embodiments are chosen and described so that others skilled in the art may appreciate and understand the principles and practices of the present invention. 
   Referring now to  FIGS. 1A-1C , a multipurpose bowl  100  is shown. While the bowl  100  is shown in this aspect of the invention as being generally ellipsoidal in shape, it should be understood and appreciated herein that the bowl  100  can have any known geometrical shape (oval, round, ellipsoidal, etc.) without affecting the function or scope of the present invention. Moreover, the bowl  100  may be either circumferentially symmetrical or asymmetrical about a central, vertical axis (not shown) without straying from the scope of the present teachings. The only requirement the bowl  100  has with respect to its shape and configuration is that it be designed in such a manner that a generally concave internal hollow containment body is created for holding food or other such items. 
   In  FIGS. 1A-1C , the bowl  100  has an upstanding peripheral wall  102  that defines the generally concave internal region  104  of the bowl and a generally flat base  106  that defines the bottom surface of the internal region  104 . The peripheral wall  102  is integral with a peripheral edge  105  of the base  106  and arcs upwardly and outwardly therefrom to terminate in a substantially vertically upwardly directed rim  108 . The rim  108  defines a geometric configuration (e.g., elliptical, round, oval, etc.) centered over the base  106  and is substantially enlarged relative thereto. Noting  FIG. 1A  in particular, in certain exemplary embodiments, the rim  108  of the bowl  100  may incline and/or decline slightly from one longitudinal end of the bowl  100  to the other longitudinal end along an arcuate path. Thus, the height of the peripheral wall  102  may vary from a maximum height at one or both ends of the bowl to a minimum height at some other point or points along the arcuate path of the rim  108 . 
   The bowl  100 , integral with the upper rim  108  thereof, also may include a peripheral outwardly extending flanged lip  110  that partially or completely surrounds the upper rim  108  of the bowl  100 . The flanged lip  110  may have a constant width as it surrounds the upper rim  108  of the bowl  100  or it may be configured such that the width varies at certain regions along the periphery of the bowl. In certain aspects of the present invention, the flanged lip  110  may also serve as a handle for carrying the bowl  100 . More particularly, a user can grasp the flanged lip  110  with their fingers to lift or carry the bowl as desired. 
   In addition to serving as handles, the flanged lip  110  may also function as a base or stage for mounting one or more objects along the upper periphery of the bowl  100 . For instance, according to one aspect of the present invention, a launching device  112  can be coupled to the flanged lip  110  of the bowl  100  for launching or propelling various objects. To secure the launching device  112  to the flanged lip  110  of the bowl  100 , any coupling/attachment means known within the art can be used. For instance, the launching device  112  can be coupled to the bowl  100  by molding, fusing, bolting, screwing, gluing, snapping, press fitting or the like. Additionally, while the launching device  112  may be permanently coupled to the flanged lip  110  of the bowl  100 , the launching device may alternatively be configured to be releasably attachable to the bowl and/or the flanged lip of the bowl by way of a coupling device. 
   The bowl  100  and launching device  112  are both made from a resilient yet somewhat flexible material, such as an elastomeric material. Known elastomeric materials capable of being used to manufacture the bowl and launching device according to the present invention include, but are not limited to, thermoplastic vinyl materials, such as polyvinyl chlorides (PVC). Those skilled in the art will appreciate, however, that other resilient and flexible materials in addition to elastomeric materials may alternatively be used to manufacture the components of the present teachings while still staying within the scope of the present invention. 
   As shown in  FIGS. 2A-2C , the launching device  112  is provided at one end of the bowl and includes a resilient handle portion  114  and a scoop portion  116  for holding one or more items to be launched by the scoop. It should be understood and appreciated herein that depending on the angle to which it is desired to launch an item from the launching device  112 , the launching device may be coupled to the flanged lip  110  at any angle with respect to the upper surface  111  of the flanged lip. For instance, in certain exemplary embodiments, the launching device  112  may be coupled to the flanged lip  110  at a 45-degree angle with respect to the upper surface  111 . In other exemplary embodiments, however, it may be desirable to couple the launching device  112  to the flanged lip  110  at an angle that is either less or greater than 45 degrees. As such, the present teachings are not intended to be limiting herein. 
   To launch an object or item from the launching device  112 , a user  118  places the object to be launched in the scoop portion  116  of the launcher and presses a tab portion  117  downwardly towards the upper surface  111  of the flanged lip  110 . Because the launching device, and particularly the handle portion  114  of the launching device, is made from a resilient material, the handle is configured to bend from a first position to a second position along a substantially vertical axis in a direction of the upper surface  111  of the flanged lip  110  without much difficulty. As shown in  FIG. 3 , when the user  118  releases the tab portion  117  of the launching device, the handle portion  114  causes the scoop  116  to return to its original relaxed state thereby propelling the object  115  into the air. 
   It should be understood and appreciated herein that a variety of objects may be propelled from the launching device  112  in accordance with the present invention. According to certain aspects of the invention, it may be desirable to launch food related items (e.g., the contents of the bowl) from the launching device. Some food related items that may be launched from the launching device  112  include, but not limited to, popcorn, candy, peanuts, pretzels, raisins, etc. 
   In addition to the launching device  112 , in certain exemplary embodiments, it may also be desirable to couple a target to the bowl  100  for receiving the launched object  115 . For instance, as shown in  FIG. 3 , a miniature basketball goal is attached to the flanged lip  110  portion of the bowl  100  to serve as a target  120  for receiving the object  115  (shown here as a piece of popcorn) that is being launched by the launching device  112 . According to this embodiment, the target  120  is placed relatively directionally across from the launching device  112  so that when the object  115  is propelled into the air, it will be launched in the general direction of the target. 
   Depending on what type of game the user desires to play (e.g., basketball, football, etc.), the target is adapted to be formed into many different shapes, such as basketball goals, football goals, etc. Additionally, while the target may be permanently coupled to the bowl  100 , the target may alternatively be configured to be releasably attachable to the bowl and/or the flanged lip of the bowl by way of a coupling device. For instance, as best shown in  FIGS. 4A-4B  and  5 A- 5 B, the targets (basketball goal and football goal, respectively)  120 ,  121  are removably attachable to the flanged lip  110  of the bowl  100  by two different attachment means. More particularly,  FIGS. 4A-4B  illustrate an attachment means in which the target  120  has a c-shaped cut-out or recess  122  at a bottom portion of the target that is adapted to be slid over the flanged lip  110 . The shape of the recess  122  is designed in such a manner that it will tightly conform to an outer rim  113  of the flanged lip  110  as it is slid over such rim. To achieve this tight fit, the amount of space between the top  122   a  and bottom  122   b  portions of the recess define a width that is slightly less than the thickness of the outer rim  113  of the flanged lip. Despite having a width less than the thickness of the outer rim  113 , the recess  122  is constructed of a resilient yet flexible material as described above. This material will allow the top portion  122   a  and the bottom portion  122   b  of the recess to slightly separate from one another as the recess is slid over the outer rim of the bowl thereby achieving a snug-like attachment of the target to the bowl. 
   An alternative means for attaching a target in accordance with the present invention is shown with reference to  FIGS. 5A-5B . According to this exemplary embodiment, the target  121  has a vertical pole  123  with an upper-flanged structure  124  and lower-flanged structure  126  that together define an internal recess  128 . To attach the target  121  to the flanged lip  110  of the bowl  100 , the bottom portion  125  of the vertical pole  123  is fitted over a hole  130  located on the upper surface  111  of the flanged lip  110 . After placing the bottom portion  125  over the hole  130 , the vertical pole is advanced downwardly until the lower-flanged structure  126  encounters the outer circumference of the hole  130  on the upper surface of the flanged lip. To advance the lower flanged structure  126  through the hole  130 , the circumference of the lower-flanged structure is configured such that it is slightly less than the circumference of the hole. After the lower-flanged structure  126  is advanced through the hole  130 , eventually the upper-flanged structure  124  will also encounter the hole  130 . Unlike the lower-flanged structure  126 , the upper-flanged structure  124  of the target  121  is shaped such that its circumference is larger than that of the hole  130 . As such, the upper-flanged structure  124  is prevented from advancing through the hole, whereby the target  121  is essentially snapped into place by sandwiching the hole with the upper and lower flanged structures. 
   After the target  121  has been attached to the flanged lip  110  of the bowl  100 , it may also be desirable to discourage the target  121  from wobbling from side-to-side as it rests upon the upper surface  111  of the flanged lip  110 . To discourage this side-to-side movement, the upper-flanged structure  124  may also comprise horizontal wings  132  that extend outwardly from the upper-flanged structure  124 . According to this embodiment, the hole  130  on the upper surface  111  of the flanged lip  110  also includes a pair of divots  131  that serve as a complementary set of horizontal wings that are designed to correspond to the horizontal wings  132  of the upper-flanged structure  124 . As such, when the target  121  is inserted into the hole  130  as explained above, the horizontal wings  132  of the upper-flanged structure  124  are aligned with the pair of divots  131  of the hole  130 . When the upper-flanged structure  124  is completely lowered into the hole  130 , the horizontal wings  132  snuggly fit into the recess formed by the pair of divots  131 . As these horizontal wings  132  extend horizontally outward from the upper-flanged structure, the target  121  is prevented from being wobbled from side-to-side. In other words, when the target  121  is moved from side-to-side, the horizontal wings  132  of the upper-flanged structure  124  will encounter the bottom surface of the pair of divots  131  and thereby be prohibited from exhibiting further horizontal movement. It should be understood that these horizontal wings are not required according to the present invention, yet may be utilized for further stability of the target if desired. Moreover, it should also be appreciated that other means for attaching a target to a bowl (or attaching a target to the flanged lip of the bowl) are possible, whereby the present teachings are not intended to be limiting herein. 
   In addition to having a launching device and/or a target, the exemplary bowls of the present invention may also comprise one or more modular inserts or compartments designed to hold a variety of items, such as food/beverage items, napkins, crayons, etc. These inserts may be permanently attached to the bowl or removably attachable thereto. One such exemplary insert is shown with reference to  FIG. 6A . According to this exemplary embodiment, insert  140  is configured to function as a dual beverage holder or carrier. It should be understood and appreciated herein that such beverage holders may vary in size and shape to accommodate different sizes of beverages as desired. Here, insert  140  has a frusto-conical figure-eight arrangement having a curved/tapered sidewall  142 , a flat or slightly concave bottom (not shown) and an open top  144  for inserting a beverage. 
   Another exemplary modular insert is shown in  FIG. 6B . According to this embodiment, the insert  146  has two recessed portions  148 ,  150  that are configured to hold a variety of items. These recessed portions  148 ,  150  each have a curved/tapered sidewall  152  and a flat or slightly concave bottom  154  and an open top  156  for inserting the objects to be held. The modular inserts can be formed of a molded pulp or a form plastic material (such as described above) that is inexpensive, disposable, heat and cold resistant, and yet capable of providing adequate resilience, strength or rigidity for simultaneously supporting a plurality of objects as described above. 
   To attach the modular inserts to the bowl, any attachment means known within the art may be used. Such exemplary attachment means include, but are not limited to, sliding, bolting, screwing, gluing, snapping or press fitting the insert to the bowl. In one aspect of the invention, the insert may include a recessed slot section that is configured to align with a complementary ridge located on the inner surface of the bowl (not shown). According to this embodiment, the user aligns the recessed slot of the insert with the internal ridge of the bowl and presses down on the insert, thereby advancing the ridge into the slot to achieve a locking fit. In yet other exemplary embodiments, the insert may include the ridge section and the bowl will have the recessed slot. It is envisioned that many other attachment means for inserting modular inserts in accordance with the present invention may also be used by those skilled within the art. As such, the present teachings are not intended to be limiting herein. 
   Turning now to  FIGS. 7A and 7B , another exemplary bowl in accordance with the present invention is illustrated. According to this embodiment, bowl  200  is shown having a substantially round upper rim  202  that together with upstanding peripheral wall  204  define a concave internal hollow containment body  206  for holding an item, such as popcorn  207 . The bowl  200 , integral with the upper rim  202  thereof, also includes a peripheral outwardly extending flanged lip  210  that surrounds the upper rim  202  of the bowl  200 . While the flanged lip  210  may have a constant width as it surrounds the upper rim  202  of the bowl  200 , in this exemplary embodiment the width of the flanged lip  210  varies at certain locations along the periphery of the bowl. The varying width of the flanged lip  210  is configured in such a manner that a variety of modular inserts  212  may be placed at desirable locations along the outer periphery of the bowl. In this illustration, the modular inserts  212  are designed to hold items such as crayons  214 , raisins  216 , napkins  218  and a drink box  220 . However, it should be understood and appreciated herein that various other alternative items may also be placed within the modular inserts as desired. 
   The upper rim  202  of the bowl  200  also includes a launching device  222  that is adapted to launch or propel an item into the air as described in detail above. In certain exemplary embodiments, the bowl may also include a divider  224  that extends vertically upward from the base (not shown) of the internal hollow containment body  206  (see FIG.  7 A). While only popcorn  207  is shown within the bowl  200  of this embodiment, it is envisioned that one may decide to use the divider  224  as a means for separating two different food and/or non-food items in other applications. Also, according to this embodiment, a target  226  to which the launching device  222  is adapted to launch an object towards is shown directly coupled to the divider  224 . As such, it should be understood that the target does not need to be attached directly to the flanged lip  210  or to the bowl itself (as explained above) to stay within the scope of the present teachings. In fact, it is also possible for the target to be placed directly into the contents of the bowl so that it is held up vertically by the weight of the bowl&#39;s contents itself. Such an arrangement is illustrated, for instance, with reference to  FIG. 7B . Here, the vertical pole  228  of the target  226  is placed down into the popcorn  207  so that it is held upright by the weight of the surrounding popcorn. 
   Another feature of the present invention as shown in  FIGS. 7A and 7B  is the incorporation of a soft outer casing  230  to the bottom of the bowl  200 . When the soft outer casing is attached to the bowl, a user  232  can hold the bowl easily and comfortably in their lap. The soft outer casing  230  can be attached to the bowl by any known attachment means known within the art such as, but not limited to, snapping, bolting, screwing, sewing, threading, gluing, molding, or by a Velcro® means. In certain aspects of the present invention, the soft outer casing  230  is attached to the flanged lip  210  of the bowl, while in other aspects of the present invention the soft outer casing is attached to the upper rim  202  of the bowl  200 . 
   The soft outer casing  230  may be permanently attached to the bowl  200  or removable from the bowl to be washed or replaced as needed. To achieve the soft characteristics desired of the outer casing, the casing  230  can be formed of a typical upholstery material or fabric and filled with small chunks of a soft and resilient material, such as styrofoam, PVC pellets or other like materials. Useful fabrics for the casing include, but are not limited to, leather, vinyl, cloth, velvet, imitation suede, canvas, etc. One exemplary example of such a material that can be used for the outer casing of the present invention is a beanbag material. Beanbag materials are known within the art and do not require further discussion herein. 
   As explained in detail above, the launching devices and targets of the present invention may be attached directly to the bowl or its flanged lip and/or attached to a divider placed into the internal hollow containment body of the bowl. In yet other aspects of the present invention, the launching device and/or target may alternatively be attached to one or more modular inserts of the bowl. For instance, as shown in  FIGS. 8A-8C , launching device  302  and target  304  are coupled to a modular insert  306  of the bowl  300 . 
   In addition to a flanged lip that is integral with the upper rim of the bowl, in other aspects of the invention, a curved ridge or shelf may also be used to discourage spillage of the contents held within the bowl. For instance, as shown within  FIGS. 9   a - 9   c , the bowl  300  includes an inwardly directed shelf  302  that is integral with the upper rim  310  of the bowl. The shelf  302  is designed in such a manner that it is curved or positioned slightly inward to create a lip at the upper surface of the bowl. In the event the bowl  300  is tilted or rotated from the horizontal, the contents contained therein will encounter the inwardly positioned shelf  302  and thereby be prevented or discouraged from spilling out of the bowl. 
   The shelf  302  may be permanently attached to the bowl  300  or configured to be removable in nature. For instance, as shown in  FIGS. 10A-10B , shelf  302  contains pegs  308  on its bottom surface, which can be aligned with a series of complementary holes  309  contained on the upper rim  310  of the bowl  300  to attach the shelf. To attach the shelf  302  to the upper rim  310  of the bowl  300 , the user inserts the pegs  308  within the holes  309  and presses down to achieve a snap fit. While this aspect of the invention shows a snap-fit arrangement of the shelf to the bowl, it is envisioned that many other attachment means known within the art can be used to achieve a similar effect. As such, the present teachings are not intended to be limiting herein. It should also be understood and appreciated that the size and shape of the shelf  302  may be modified as desired to achieve various levels of protection for preventing the contents of the bowl from spilling out when the bowl is tilted past the horizontal. 
   In addition to attachable shelves, the exemplary bowls of the present invention may also comprise one or more attachable handles to the outside surface of the bowl. For instance, as shown in  FIGS. 11A and 11B , curved handle  312  is coupled to the outside surface  314  of the bowl  300 . Once attached to the bowl  300 , a user can grasp underneath the curved handle  312  with their fingers to lift or carry the bowl as desired. Such exemplary handles can be attached to the bowl  300  by any attachment means known within the art, such as, but not limited to, molding, fusing, bolting, screwing, gluing, snapping, press fitting or the like. 
   Another feature of the present invention as shown in  FIG. 12  is the incorporation of a curved or contoured shape to one or more of the end walls  316  of the bowl. By designing the bowl to include such an exaggerated contoured shape, a user can hold the bowl  300  in their lap easily and comfortably during use. 
   Still other features of the present invention include the incorporation of a bottom section to the bowl that is designed to separate popped popcorn from unpopped popcorn kernels. For instance,  FIG. 13  shows a bowl  400  having an upstanding peripheral wall  402  that defines a generally concave internal region  404  of the bowl and a generally flat base  406  that defines the bottom surface of the internal region  404 . Peripheral wall  402  is integral with a peripheral edge  405  of the base  406  and arcs upwardly and outwardly therefrom to terminate in a substantially vertically upwardly directed rim  408 . In addition to the flat base  406  that defines the bottom of the bowl, the bowl  400  also includes a horizontal separator section  410  that is substantially parallel to the base  406  of the bowl. The separator section  410  includes a series of openings (not shown) each of which have a diameter or width that is larger than the diameter or width of a typical popcorn kernel, yet smaller than the typical diameter or width of a piece of popped popcorn.
