## Background
FIELD OF THE DISCLOSURE
The present disclosure relates generally to the field of mixing containers and methods for mixing liquids. More particularly, the present disclosure relates to an improved mixing container with an integrated stirring flap that provides for the easy mixing of liquids contained therein.
BACKGROUND
The beverage mixing process requires the use of a stirrer to mix the components of the beverage contained in the mixing container. Users are required to hold the drinking cup with one hand and stir the liquid using the other hand. Cups with self-contained spoons or paddles have been used by individuals for mixing liquids. These cups are typically designed with integrated stirrers or paddles to aid in an effective mixing process. These cups include a stirrer attached to the inner side of the cup that needs to be torn off by the user which can cause damage to the cup. The user must hold the cup in his hand and stir the liquid using the other hand. This type of mixing entails inconvenience to the user.
With existing mixing devices, the user has to repetitively stir the liquid. Repetitive stifling increases the potential for spillage which in turn causes difficulty to the user, even burning if the liquid is hot. Mixing cups may be made of paper, cardboard, foam, or plastic. The stirrer, spoon or paddle may be integrated within these mixing containers. The user must tear off the stirrer from these cups and use it for stirring. While tearing off the stirrer from the cups, the cups may be easily damaged. Some of the mixing devices make use of a spring-loaded stifling device which in turn makes the manufacture of the cup complex and expensive.
Some mixing devices incorporate a plate with fins on the bottom portion. After pouring liquid in the cup, the user must grasp the bottom portion and rotate the cup alternately in a clockwise and counter-clockwise direction until the sugar is dissolved. This type of cup is also difficult to manufacture. In addition, the user may find it difficult to continuously rotate the cup to dissolve the sugar.
Some conventional beverage mixing containers include a fluid mixer to be inserted into a mixing container. The container needs to be reciprocally rotated by the user so as to mix the liquid. The fluid mixer has a plurality of blades to move the fluid upwards and downwards upon reciprocal rotation of the container. This type of mixing is time-consuming and complex. The user often finds it difficult to remove the mixer from the container.
Therefore, there is a need for a simple liquid mixing container that allows the user to easily and safely mix the liquid within. As such, the container should be easy to manufacture. The needed container contains an integrated stifling flap that allows liquid to move easily within. The needed container eliminates the need for stirring continuously to effectively mix the liquid. The liquid would be easily and safely mixed when the user grasps the container and moves it in a circular motion. Finally, the needed container also incorporates a plurality of perforations that allows liquid to move simply and effectively without causing difficulty to the user.

The present invention comprises a beverage container 1 for mixing a beverage. The beverage container 1 includes a cup 2 having a stifling flap 3 integral to an internal side wall 4 of the cup 2. The stifling flap 3 extends internally inside the cup 2. The stifling flap 3 comprises a top fin 5 protruding near the top of the internal wall 8 of the cup 2 and a bottom fin 6 protruding near the bottom of the internal wall 9 of the cup 2. The top fin 5 and the bottom fin 6 are separated by a central portion 10. The cup 2 may be swirled in a circular motion by a person's hand 14 to mix the liquid contained within. The central portion 10 has minimal material so as to allow liquid to pass freely through the middle of the cup 2 to gain momentum when the cup 2 is swirled.
The stifling flap 3 has a sine wave shape with a rounded tip 7 on the top fin 5. The rounded tip 7 extends just below the surface of liquid contents of the cup 2 when the cup 2 is full, thereby causing the liquid contents to fold on to itself when the cup 2 is swirled, thereby minimizing liquid from escaping the cup 2. The bottom fin 6 has the shape of a lower case letter ‘h’, thereby allowing solid material that may gather in the bottom of the cup 13 to pass underneath the bottom fin 6 and mix with the liquid. The stifling flap 3 is perforated and the stirring flap 3 includes perforations 11. The perforations 11 comprise a plurality of substantially circular holes 12, wherein each of the substantially circular holes 12 has a diameter between three sixteenths of an inch and six sixteenths of an inch. The top fin 5 includes exactly 3 holes 12 and the bottom fin 6 also includes exactly 3 holes 12 to allow liquid to pass and mix as the circular movement of liquid creates vortex inside the cup 2, when the cup 2 is rotated in circular motion by a user.
The beverage container 1 may be utilized for mixing liquids such as beverages. The cup 2 is made of disposable material selected from the group consisting of paper, cardboard, foam, and plastic and the stifling flap 3 comprises an extension of the disposable material that extends past a glue point of the cup 2. The top fin 5 and the bottom fin 6 are integral to the cup 2 as they are portions of the stirring flap 3 cut out of the same disposable material as of the cup 2.
As discussed in the background section, while mixing liquids, the user must rotate the mixing cup alternately in a clockwise and counter-clockwise direction until the sugar is dissolved which can cause difficulty to the user. The present invention provides the simple beverage container 1 that allows the user to easily and safely mix the liquid contained within. The container 1 is adapted for allowing the liquid to move simply and effectively without causing difficulty to the user.
The method may include providing the beverage container 1 to the user and swirling the beverage container 1 in a circular motion by the person's hand 14. The cup 2 is capable of being swirled by the person's hand 14. The rotational movement of a grasping hand 14 in a circular motion on the cup 2 will generate a circular moving liquid inside the cup 2 thereby creating a centrifugal force that pushes the liquid against the stirring flap 3 to effectively mix the liquid. While swirling, the rounded tip 7 of the sine wave shaped stirring flap 3 allows the liquid to fold on to itself thereby minimizing the liquid from escape from the cup 2. The ‘h’ shaped bottom fin 6 allows the solid material gathering at the bottom of the cup 13 to pass underneath the bottom fin 6 and mix with the liquid. This allows the solid material to mix effectively with the liquid. The substantially circular holes 12 on the top fin 5 and the bottom fin 6 allows the liquid to pass through and mix as the circular movement of the liquid creates vortex inside the cup 2 when the person's hand 14 moves up in a circular motion.
One of the main advantages of this container 1 is the integrated stifling flap 3 that allows the user to easily mix the liquid by swirling the cup 2 thereby providing a simple, convenient and ease of use. Another advantage of the present invention is that the ‘h’ shaped bottom fin 6 allows the solid material gathered at the bottom of the cup 2 to be easily mixed with the liquid.
In preferred embodiment, the present invention may be customized as an ideal liquid mixing device. The beverage container 1 may be easily manufactured with less number of components which makes it more economical. Further, the beverage container 1 may be easily swirled by the person's hand 14. Also, the container 1 is made of disposable material which makes it to be easily disposed by the user.
Although the description above contains many specifications, these should not be construed as limiting the scope of the invention but as merely providing illustrations of some of the embodiments of this invention. Thus, the scope of the invention should be determined by the appended claims and their legal equivalents rather than by the examples given.
