DISCLOSURE OF THE INVENTION
In the past brewing a beverage such as tea and coffee have been accomplished by pouring hot or boiling water over tea leafs or coffee grounds and letting the product steep until the desired strength is accomplished and then removing or straining the residue before use. In today's world time is important and many would like to have the ability to carry the beverage with them when in a vehicle or at work on a personal basis. Previously it is necessary to have a brew pot separate from a travel mug which requires a heat source or at least access to hot water and a separate container for carrying.
It is therefore a primary object of the invention to combine a vacuum insulated travel mug with a removable filter basket allowing the user to simply add hot water over the filter basket to the product and be able to remove and store the residue when the beverage is properly brewed. The invention provides this convenience all in one self contained multi-function package.
An important object of the invention is in its flexibility as it is not only a brewer but permits the user to enjoy the beverage while traveling as the mug is of a convenient size to fit into conventional cup holders generally provided in modern vehicles. Since it is insulated the beverage stays hot for extended periods of time.
Another object of the invention is the ease of storage of the residue remaining from the tea leafs or coffee grounds as a holding cup is nested onto the bottom portion of the travel mug and is easily removed by separating the two items. When the brewing is completed the filter basket is removed from the mug and placed in the holding cup with a cover provided that seals the cup therefore permitting the user to drink directly from the mug.
Still another object of the invention is realized with the storage container provided that retains a quantity of product for further brewing and the container also acts as a stopper when the mug is empty. The invention provides supplementary storage space within the holding cup for additional residue.
A final object of the invention is its convenience since it provides brewing directly in the travel mug for drinking with storage of the residual tea leafs or coffee grounds in a separate holding cup, both of which have lids to prevent spillage. Further the travel mug may be used by itself with hot or cold beverages or likewise the cup may be used separately for any liquid holding purpose.
These and other objects and advantages of the present invention will become apparent from the subsequent detailed description of the preferred embodiment and the appended claims taken in conjunction with the accompanying drawings.

A filter basket 26, illustrated in FIGS. 4, 5 and 11 is used for holding beverage tea leafs or coffee grounds and is removably disposed within the top opening 22 of the travel mug 20. When hot water is poured over tea leafs or coffee grounds within the filter basket 26 a brewed beverage is created within the travel mug 20. The filter basket 26 preferably utilizes a stainless steel mesh screen 28 that is inserted circumferentially within a thermoplastic cage 30. The filter basket 26 is used to contain beverage leafs and grounds. When hot water is poured over this product a consumable beverage is produced. The filter basket cage 30 incorporates a perforated bottom 32 and is constructed of a thermoplastic material such as polypropylene, acrylic, allyl diglycol carbonate, polycarbonate, polystyrene, polysulfone, polyester sulfone or polyester.
A basket/cup cover 34 is provided that fits snugly into a top surface of the filter basket 26, as illustrated in FIGS. 4, 5 and 10 and is recessed with a flange on the top and incorporates a lifting tab 36 on one side. Again the material may be polypropylene, acrylic, allyl diglycol carbonate, polycarbonate, polystyrene, polysulfone, polyester sulfone or polyester.
A storage container 38 is removably disposed onto a top portion of the basket/cup cover 34 and is used for retaining beverage tea leafs or coffee grounds. The storage container 38 is depicted in FIGS. 5, 6 and 9 and includes a storage container lid 40, shown alone in FIG. 5, which is removably attached to the storage container 38 for enclosing contents retained therein, i.e. tea leafs or coffee grounds. The storage container 38 includes a recessed groove 42 and a circumferential gasket 44 imbedded within this recessed groove 42, as illustrated in the cross section drawing of FIG. 4. Further hand gripping protrusions 46 are provided around a peripheral edge of the container 38 for use when removing the container 38 from the basket/cup cover 34.
