CROSS-REFERENCE TO RELATED APPLICATION(S)- This application is related to and claims priority benefits from U.S. Provisional Patent Application Ser. No. 61/867,030 filed Aug. 17, 2013 entitled “Beverage Container with Integral Receptacle for Interchangeable Insert”. The '030 provisional application is hereby incorporated herein by reference in its entirety. 
FIELD OF THE INVENTION- The present invention relates to beverage containers and, in particular, beverage containers with interchangeable indicia. In some embodiments an integral receptacle holds the interchangeable decorative inserts. In other embodiments the indicia is wrapped around the container. 
BACKGROUND OF THE INVENTION- In food and beverage establishments, it is common to use beverage containers that display on their exterior surface various brand names, logos, sports team names and decorative indicia generally. Such conventional beverage containers commonly have such indicia permanently printed or embossed on their exterior surfaces such that new containers are required when the establishment transitions to a different motif. For example, a sports bar may wish to promote a particular baseball team during the spring and summer when baseball is in season, and then switch to promoting a particular football team in the fall and winter. The beverage glasses with the baseball team's name and logo have to be switched out and stored when football season begins and the bar wants to use the beverage glasses with the football team's name and logo. 
- Instead of switching out permanently printed beverage containers, it would be advantageous to use the same container and switch out the printed labels displaying indicia normally printed or embossed directly on the container's exterior surface. The problem encountered with the use of interchangeable labels is their inability to remain adhered to the containers for a sufficiently long period of time. Even when adhered, labels can become scratched and pitted, diminishing the quality of the container's appearance and message intended to be conveyed by the label. 
SUMMARY OF THE INVENTION- The above and other shortcomings of conventional container designs are overcome by a fluid container comprising: 
- (a) a base having at least one wall extending upwardly from the base, the at least one wall having an interior surface for contacting the fluid and an oppositely-facing exterior surface, the at least one wall terminating in an edge defining a lip for accommodating the drinking of the fluid from the container; and
- (b) a receptacle formed in the at least one wall exterior surface, the receptacle configured to interchangeably mount an insert having indicia displayed thereon.
 
- In one embodiment, the receptacle has a side wall with a notch formed therein for accommodating a utensil for prying the insert from the receptacle. 
- In some embodiments, interior surface of the container is cylindrical. In other embodiments, it is multisided. 
- In one embodiment, the interior wall of the receptacle has a ferromagnetic substance deposited thereon. The ferromagnetic substance retains the insert against the receptacle interior wall when the insert has a corresponding ferromagnetic substance deposited thereon. In other or the same embodiment, the side wall of the receptacle contains the ferromagnetic substance. 
- In some embodiments, the receptacle interior wall has an adhesive substance deposited thereon that retains the insert against the receptacle interior wall. 
- In some embodiments, at least one receptacle side wall is at least partially convex such that the insert is capable of being press-fitted and retained within the receptacle. 
- In one embodiment, the receptacle side wall is circular and the insert is a circular disc. In another embodiment, the receptacle side is made up of a plurality of walls and the insert is polygonal. When the plurality of receptacle side walls comprises four receptacle side walls, the receptacle accommodates a rectangular insert. 
- Shortcomings of conventional designs are also overcome by making a fluid container with an integral receptacle for interchangeably mounting an insert having indicia displayed thereon. The method comprises forming a receptacle in an exterior surface of the container. The receptacle comprises a recessed interior wall and at least one side wall interconnecting the receptacle interior wall and the container exterior surface. The receptacle is configured to interchangeably mount an insert having indicia displayed thereon. 
- In some embodiments the receptacle is not recessed with respect to the exterior surface of the container. Instead the receptacle can protrude outward from the exterior surface so the receptacle and the indicia it holds are raised with respect to the exterior surface of the container. 
- In some embodiments, the method further comprises forming a notch in the at least one receptacle side wall. The notch accommodates a utensil for prying the insert from the receptacle. 
- In one embodiment, the method further comprises depositing a ferromagnetic substance on the receptacle interior wall. The ferromagnetic substance retains the insert against the receptacle interior wall when the insert has a corresponding ferromagnetic substance deposited thereon. In some embodiments, the method further comprises depositing an adhesive substance on the receptacle interior wall. The adhesive substance retains the insert against the receptacle interior wall. 
- In one embodiment of the method, a receptacle side wall is at least partially convex such that the insert is capable of being press-fitted and retained within the receptacle.
