Abstract:
A system for providing an infusion chamber provides a clip assembly for attachment within a drinking vessel. A box assembly contains an infusion chamber and may be attached to the clip assembly. The box assembly has a top swinging lid to accept dry ice and other materials suitable for infusion. The bottom of the box assembly features a communication void or slot at the bottom of the box to allow the contents of the box assembly to mix with the surrounding drink, but yet not fall loose into the drink. The clip features contoured adhesive wedges to assist in attachment of the clip to the inside portions of a drinking container. The clip assembly has a thin stop tab or shelf that fits into the box assembly. A side hook from the box assembly is supported by the lower portion of the stop tab or shelf of the clip assembly. The upper or top side of the stop tab or shelf is trapped by a stop tab of the box assembly. The use of dry ice within the box assembly and use of liquid such as punch in the drinking vessel, may result vapor from the dry ice to rise though the drink and out of the drink, to create a witches brew effect while cooling and mixing but not diluting the drink as typical with ice made from water.

Description:
BACKGROUND OF THE INVENTION 
     (1) Field of the Invention 
     The invention generally relates to means and methods of containing dry ice within a beverage container. More particularly, the invention relates to a dry ice container box or infuser box using a retaining clip to provide an interface between the box and beverage container. 
     (2) Description of the Related Art 
     Several methods of using dry ice within a beverage container are known in the related art. The current zenith in the art was disclosed on Sep. 25, 2007 in U.S. Pat. No. 7,272,950 by Roman (the &#39;950 patent) wherein a fixed section is attached to a drinking glass and a movable section acts as a permeable cap to retain dry ice. While innovative and novel, the &#39;950 patent does not contemplate a sealant failure wherein the fixed portion may break free and allow the dry ice to escape into the glass. Thus, what is needed in the art are means and methods of securing a portion of dry ice within a drinking container, such that an attachment failure will not lead to an escape of dry ice or other contained material. 
     BRIEF SUMMARY OF THE INVENTION 
     The present invention overcomes shortfalls in the related art by presenting unique and novel methods and devices to redundantly secure dry ice or other material within a drinking container. The present invention provides unexpected results and utility by using a self enclosing box container with means of attachment to a clip, the clip being attached to a standard or customized drinking container or drinking glass. The disclosed clip or clip assembly is comprised of form fitting components to assist in the snug fit of the clip within the drinking container. The use of non toxic adhesives may be used to assist in the attachment of the clip to the inside surfaces of the drinking container. The box assembly uses a living hinge or other means to safely and conveniently secure dry ice or other contents. The disclosed box assembly includes a vent design suitable for allowing the retained dry ice (or other item for infusing) to communicate with the outer consumable liquid. But yet, the box design prevents the solid contents of the box from directly entering the mouth of the user. 
     The present invention overcomes shortfalls in the &#39;950 patent by providing insulation between the dry ice and the drink. The &#39;950 patent immediately exposes all contained dry ice to the drink, thus cooling the glass and shortening the time of fog generation. The present invention provides a box that holds and insulates the dry ice or other infusing material. The clip assembly minimizes the path of direct contact of dry ice to the glass, providing unexpected results by greatly prolonging the generation of the desired fog or witches brew effect. 
     The present invention overcomes short falls in the art by providing a two piece interlocking system that allows for one type of material, in the form of a clip assembly, to be affixed or glued to the drinking vessel or drinking glass while a different type of material, in the form of a box assembly, may be used to secure the dry ice or other infusing material. For a box assembly or container to hold the dry ice, it is desirable to have a living hinge to access the box compartment. But, the type of material ideal for construction of a living hinge is not well suited for gluing or otherwise attaching to the inside of a drinking container. Moreover, materials suited for attachment to glass have properties that are not conducive to construction of a box assembly. The disclosed invention provides unexpected results by allowing for the use of the best materials for flexibility in a box assembly and by simultaneously allowing for the best materials to be used for attachment to a drinking vessel. The invention also allows for the clip assemble to be molded into a drinking glass while the box assembly may be inserted by the consumer. 
     The disclosed assembly may interlock with the disclosed box assembly to allow for the clip assembly to be permanently attached to a drinking vessel and for the box assembly to be removed, replaced, cleaned and otherwise maintained. 
     One aspect of the invention includes the use of dry ice or solidified CO 2  to be introduced within a consumable beverage. Solidified CO 2  starts in the form of a cold solid, and when exposed to typical ambient room temperature, sublimates directly into a vapor or gas state, bypassing the liquid state, unlike frozen water. Hence, solidified CO 2  is commonly referred to as “dry ice” as no liquid is formed by CO 2  at any household temperature. When solidified CO 2  reaches room temperature, a visible fog, is created. Solidified CO 2  may be inserted within a consumable liquid, such as punch, wherein the warming of the CO 2  results in a fog mysteriously rising out of the punch and into the ambient air. This effect is sometimes referred to as “witches brew”. In the Halloween season and on other occasions there is a commercial demand for means of creating witches brew. 
     Solidified CO 2  is typically sold in large blocks or in pellet form. For individual beverages, the use of solidified CO 2  in pellet from is common. While solidified CO 2  is not toxic, the unanticipated consumption of any pellet or solid object within a beverage may lead to choking and is very undesirable. The present invention overcomes a shortfall in the art by providing a self closing box or infusion box that remains closed even in the event of detachment from the user&#39;s glass or drinking container. 
     In addition, the sublimation creates bubbles which causes a mixing action which obviates the need for stirring or shaking a drink to mix. Furthermore, the dry ice does not dilute the drink as compared to the use of ice wherein water from the ice mixes with the drink. 
     These and other objects and advantages will be made apparent when considering the following detailed specification when taken in conjunction with the drawings.

       FIG. 17  is a top plan view of a box assembly  200  attached to the clip assembly  300  and a drinking vessel  500  attached to the clip assembly. In this embodiment, the optional bar  305  can be seen in the clip assembly as well as the top surface  251  of the lid. 
       FIG. 18  is a cross sectional view of one embodiment of the invention displaying a communication void  240  located within lower portion of a box assembly  200 . The communication void  240  allows the contents of the box assembly to mix or interact with the contents of the drinking vessel  500 , but yet not fall into the contents of the drinking vessel. The unobvious combination of a lower communication void within a otherwise solid dry ice container box provides unexpectedly good results in prolonging or extending the melting time of dry ice as compared to the related art. The insulation qualities of a nearly enclosed box assembly keep the dry ice cold and keep the drink contents warm, thus extending the time in which the dry ice is infused into the drink, allowing for a greater time period of witches brew emanating from the surface of the drink. The slot configuration of the disclosed invention places the mixing of dry ice with the drink at points in the bottom of the drink, and thus adds emphasis the effect of fog rising from the bottom of the drink to the surface of the drink. (See above for explanation of the insulating effect). 
       FIG. 19  is an enlarged cross section view of a clip assembly  300  and box assembly  200  showing a side hook  201  of the box assembly engaged with the lower side of the stop tab shelf  302  of the clip assembly. The upper side of the stop tab shelf  302  rests under the stop tab  220  of the box assembly. Just above each side retaining hook  201  is a matching void or recess  304  within portions of the stop tab shelf  302 . Void  304  acts as side retaining hook release. In order to remove the box from the clip, pressure may be applied within recess  304  within the stop tab for shelf  302  in order to release the stop tab for shelf  302  from the grasp of the side retaining hook  201  of the box assembly and stop tab  220  of the box assembly. 
       FIG. 20  is a cross sectional view of a drinking glass  500 , clip assembly and box assembly  200  showing an area  510  for garnish or similar items. Dry ice  50  or other material is shown within the box assembly  200 . 
       FIG. 21  is a side, cross sectional view of a box assembly  200  with a closed lid, resulting in the top surface  251  of the lid facing away from the box. Lid cantilever hook  253  is shown in a locked position.  FIG. 22  is a side cross sectional view of a box assembly  200  with the lid in an open position, exposing the bottom surface  252  of the lid. Lid cantilever hook  253  is shown in an unlocked position.  FIG. 23  is a top view of a box assembly with the lid in an open position. A communication slot  240  is visible at the bottom of the box assembly. A stop tab  220  and side hook  201  are also marked.
