Description
BACKGROUND OF THE INVENTION

1. Field of the Invention


This invention relates generally to the field of consumer packaging, and more specifically to containers that are used to package a beverage mixture and to facilitate use of the beverage mixture by a consumer


2. Description of the Related Technology


A variety of beverage mixture materials such as dehydrated pastes, granules, powders or frozen material have been packaged for sale to consumers for eventual reconstitution into a beverage, soup or edible slurry.


Some mixture materials are packaged in such a manner that the consumer must remove the mixture material from the packaging and place it within a separate vessel or container for mixing with a liquid such as water or milk. This can be done by removing a portion of the mixture material from the packaging container using an implement such as a spoon, or by pouring it directly from the packaging after opening.


In other cases, the original packaging container has been constructed in a manner that will permit a liquid additive to be mixed with a liquid or other material while it is still in the original packaging. However, it has often challenging for the consumer to thoroughly mix the respective materials within the original packaging to the extent that is necessary to ensure optimal food or beverage quality.


Using an agitator such as a stir straw or a spoon can take an extended period of time to achieve the optimal amount of mixing. In addition, such an article may not be readily available. Shaking the container in order to mix the material in the liquid additive can also be limited in its effectiveness because the geometry of conventional containers is not optimized to promote mixture by shaking. Shaking some containers when a liquid is inside can also result in leakage from the container.


A need exists for an improved method and apparatus for packaging a beverage mixture that will permit thorough mixing of the beverage mixture with an additive material to be achieved within the original product packaging with minimal effort by the consumer and with minimal risk of leakage.


SUMMARY OF THE INVENTION

Accordingly, it is an object of the invention to provide an improved method and apparatus for packaging a beverage mixture that will permit thorough mixing of the beverage mixture with an additive material to be achieved within the original product packaging with minimal effort by the consumer and with minimal risk of leakage.


In order to achieve the above and other objects of the invention, a container for packaging a beverage that needs to be agitated before drinking according to a first aspect of the invention includes a main body portion having a side wall that defines an interior space. The main body portion has an upper mounting portion defining an opening that is in communication with the interior space, and a closure member that is releasably securable to the upper mounting portion. The main body portion is shaped so as to define a lower portion having a first volume, an upper head portion having a second volume and an agitator portion defined in the side wall between the lower portion and the upper head portion. This facilitates amplified mixing of the contents of the container when the container is shaken by a consumer.


According to a second aspect of the invention, a method of making a beverage that needs to be agitated before drinking includes steps of providing a container assembly having a main body portion that has a side wall that defines an interior space and an upper mounting portion to which a closure is releasably secured. The main body portion has a lower portion that is at least partially filled with a first substance. The lower portion defines a first volume, an upper head portion having a second volume and an agitator portion defined in the side wall between the lower portion and the upper head portion. The closure will then be removed, and a second substance will be added to the container assembly. The closure will be replaced, and the container assembly will be shaken so that the agitator portion promotes mixing of the contents therein.


These and various other advantages and features of novelty that characterize the invention are pointed out with particularity in the claims annexed hereto and forming a part hereof. However, for a better understanding of the invention, its advantages, and the objects obtained by its use, reference should be made to the drawings which form a further part hereof, and to the accompanying descriptive matter, in which there is illustrated and described a preferred embodiment of the invention.
