Structure/Materials
There are a variety of tumbler with convertible lid and coaster implementations. Referring to FIG. 1, a side view of a tumbler and a convertible lid and coaster assembly is illustrated. In some implementations, tumbler 2 may comprise an open end 1 (FIGS. 2 and 3), brim 3, interior side wall 8 and exterior side wall 7. Tumbler 2 may comprise one or more lugs 6 located on interior side wall 8. Lugs 6 may be formed integrally with tumbler 2 or may be formed separately and thereafter coupled with tumbler 2. The one or more lugs 6 may comprise any size or shape that may allow them to removably couple with one or more convertible lid and coaster grooves 16. In some implementations, one or more convertible lid and coaster grooves 16 may be tapered, that is, they may comprise a wide end and a narrow end. In some implementations, one or more lugs 6 may be oriented obliquely with respect to brim 3. In certain implementations, an edge of one or more lugs 6 may be oriented one of at a right angle with and parallel to brim 3. It will be understood that both lug 6 and convertible lid and coaster groove 16 may comprise any shape, size or dimension as long as, together, they provide a removably locking fit when lug 6 is nestled or wedged about a portion of convertible lid and coaster groove 16.
In particular implementations, when the position of lug 6 moves toward a comparatively narrow end of convertible lid and coaster groove 16 (with lug 6 aligned in convertible lid and coaster groove 16), lug 6 may become wedged about the narrow end of convertible lid and coaster groove 16 and may provide a removably locking fit between convertible lid and coaster 4 and tumbler 2. In contrast, when the position of lug 6 moves toward the comparatively wide end of convertible lid and coaster grooves 16 (with lug 6 still aligned in convertible lid and coaster groove 16), lug 6 may become un-wedged from about the narrow end of convertible lid and coaster groove 16 and may thus unlock the removable fit between convertible lid and coaster 4 and tumbler 2. Alternatively, it will be understood that the relative positions of lug 6 and convertible lid and coaster groove 16 may be reversed, so that the grooves are located on interior side wall 8 of tumbler 2 and the lugs are located on side edge 11 of convertible lid and coaster 4. In alternative implementations, lug 6 may comprise a pressure bump, or other protrusion configured to removably wedge or nestle, through a pressure fit, within convertible lid and coaster groove 16.
Still referring to FIG. 1, tumbler 2 may further comprise bottom portion 10 and one or more tumbler bottom grooves 12. Tumbler bottom grooves 12 may be formed integrally with the tumbler during manufacture, or may be formed after the manufacture of the tumbler. In some implementations, one or more tumbler bottom grooves 12 may be tapered, that is, they may comprise a wide end and a narrow end. It will be understood that both lug 23 and tumbler bottom grooves 12 may comprise any shape, size or dimension as long as, together, they provide a removably locking fit when lug 23 is nestled or wedged about a portion of tumbler bottom grooves 12. In particular implementations, when the position of lug 23 moves toward a comparatively narrow end of tumbler bottom grooves 12 (with lug 23 aligned in tumbler bottom grooves 12), lug 23 may become wedged about the narrow end of tumbler bottom grooves 12 and may provide a removably locking fit between convertible lid and coaster 4 and tumbler 2.
Convertible lid and coaster 4 may comprise top surface 22, side edge 11 and one or more convertible lid and coaster grooves 16 in side edge 11. Convertible lid and coaster grooves 16 may be formed integrally in side edge 11 of the convertible lid and coaster 4 contemporaneously during manufacture of convertible lid and coaster 4, or may be formed after the manufacture of convertible lid and coaster 4 by milling, routing, or any other appropriate technique known in the art.
For the exemplary purposes of this disclosure, tumbler 2 and convertible lid and coaster 4 may be formed of: polymers and/or polycarbonates or other like materials; plastics, and/or other like materials; composites and/or other like materials; glass and/or other like materials; ceramics and/or other like materials; porcelain and/or other like materials; metals and/or other like materials; alloys and/or other like materials; and/or any combination of the foregoing. Some components forming a tumbler with convertible lid and coaster may be manufactured simultaneously and integrally joined with one another, while other components may be purchased pre-manufactured or manufactured separately and then assembled with the integral components. Accordingly, manufacture of these components separately or simultaneously may involve vacuum forming, injection molding, blow molding, milling, drilling, reaming, stamping, pressing, cutting and/or the like. Various implementations may be manufactured using conventional procedures as added to and improved upon through the principles described herein.
FIG. 2 illustrates a top view of tumbler 2 and convertible lid and coaster 4. Tumbler 2 comprises open portion 1, brim 3, interior side wall 8 comprising one or more lugs 6, and exterior side wall 7.

Convertible lid and coaster 4 may be situated within open portion 1 (FIGS. 1 and 3) of tumbler 2. One or more lugs 6 located on interior side wall 8 of tumbler 2 may be aligned and engaged with one or more convertible lid and coaster grooves 16 on convertible lid and coaster 4. It will be understood that the interaction of the one or more lugs 6 with one or more convertible lid and coaster grooves 16 may provide a removably locking fit.
FIG. 6 illustrates a perspective view of tumbler 2 removably coupled with a convertible lid and coaster 4. Convertible lid and coaster 4 may comprise one or more finger recesses 18 that may be grasped by one or more fingers (or other extensions) of a user. Convertible lid and coaster 4 may further comprise securable straw hole 20 that may be opened or closed, maintained in an open or closed position, and may accommodate the insertion of a drinking straw when in an open position. Convertible lid and coaster 4 may further be removably coupled with open end 1 of tumbler 2 such that one or more lugs 6 on interior wall 8 of tumbler 2 may removably interlock with one or more convertible lid and coaster grooves 16. Significantly, when convertible lid and coaster 4 is removably locked within the open end of tumbler 2, top surface 22 of convertible lid and coaster 4 may remain flush with respect to brim of glass 3.
Use
Referring to FIG. 1, the operation of a tumbler with a convertible lid and coaster is illustrated. It will be understood that convertible lid and coaster 4 may be removably coupled within either open end 1 of tumbler 2 or with bottom portion 10 (FIG. 1) of tumbler 2. A user desiring to removably couple convertible lid and coaster 4 within open portion 1 of tumbler 2 may grasp and thereafter insert convertible lid and coaster 4 into the open end of tumbler 2 so that top surface 22 of convertible lid and coaster 4 faces skyward and is oriented substantially parallel to bottom portion 10 of tumbler 2. A user desiring to grasp convertible lid and coaster 4 may do so by inserting their finger into one or more finger recesses 18. Alternatively, a user may grasp any other portion of convertible lid and coaster 4 that may allow a user to manipulate convertible lid and coaster 4 in a desired manner.
Once convertible lid and coaster 4 is inserted by a user within the open end of a tumbler 2 in the foregoing manner, a user may align one or more lugs 6 with one or more convertible lid and coaster grooves 16. Once a user has aligned one or more lugs 6 with one or more convertible lid and coaster grooves 16, a user may thereafter rotate convertible lid and coaster 4 with respect to tumbler 2 in order to removably lock convertible lid and coaster 4 into a fixed position relative to tumbler 2.
In particular, when convertible lid and coaster 4 is rotated (with lug 6 aligned in convertible lid and coaster groove 16) so that the position of lug 6 moves toward the comparatively narrow end of convertible lid and coaster groove 16, lug 6 may become wedged in the narrow end of convertible lid and coaster groove 16 in order to provide a removably locking fit between convertible lid and coaster 4 and tumbler 2. In contrast, when convertible lid and coaster 4 is rotated (with lug 6 aligned in convertible lid and coaster groove 16) so that the position of lug 6 moves toward the comparatively wide end of convertible lid and coaster groove 16, lug 6 may become un-wedged from the narrow end of convertible lid and coaster groove 16 and may thus unlock the removable fit between convertible lid and coaster 4 and tumbler 2. It will be understood that convertible lid and coaster 4 and tumbler 2 may be configured so that a clockwise or a counterclockwise rotation of convertible lid and coaster 4 with respect to tumbler 2 may cause to convertible lid and coaster 4 to removably tighten with respect to tumbler 2.
The operation of tumbler 2 removably coupled with a convertible lid and coaster 4 illustrated in the top view of FIG. 2 will now be described. Once again, convertible lid and coaster 4 may be removably coupled with either open portion 1 of tumbler 2 or bottom portion 10 (FIG. 1) of tumbler 2. A user desiring to removably couple convertible lid and coaster 4 within open portion 1 of tumbler 2 may grasp convertible lid and coaster 4 by one or more finger recesses 18 and thereafter insert convertible lid and coaster 4 into the open end of tumbler 2 so that top surface 22 of convertible lid and coaster 4 faces skyward and is oriented substantially parallel to bottom 10 of tumbler 2. Once a convertible lid and coaster 4 is inserted within the open end of a tumbler 2 in the foregoing manner, a user may align one or more convertible lid and coaster grooves 16 with one or more lugs 6 and thereafter rotate convertible lid and coaster 4 while securely holding tumbler 2, in order to removably lock convertible lid and coaster 4 into a fixed position relative to tumbler 2. Alternatively, a user may rotate tumbler 2 while securely holding convertible lid and coaster 4, in order to removably lock tumbler 2 into a fixed position relative to convertible lid and coaster.

When convertible lid and coaster 4 is rotated (with convertible lid and coaster lug 23 aligned in tumbler bottom groove 12) so that the position of convertible lid and coaster lug 23 moves toward the comparatively narrow end of tumbler bottom groove 12, convertible lid and coaster lug 23 may become wedged in the narrow end of tumbler bottom groove 12 and may provide a removably locking fit between convertible lid and coaster 4 and tumbler 2. In contrast, when convertible lid and coaster 4 is rotated (with convertible lid and coaster lug 23 aligned in tumbler bottom groove 12) so that the position of convertible lid and coaster lug 23 moves toward the comparatively wide end of tumbler bottom groove 12, convertible lid and coaster lug 23 may become un-wedged from the narrow end of tumbler bottom groove 12 and may thus unlock the removably locking fit between convertible lid and coaster 4 and tumbler 2.
Still referring to FIG. 3, a user desiring to removably couple convertible lid and coaster 4 within open portion 1 of tumbler 2, may grasp convertible lid and coaster 4 by inserting one or more fingers into the one or more finger recesses 18 and thereafter inserting convertible lid and coaster 4 into the open end of tumbler 2 so that top surface 22 of convertible lid and coaster 4 faces skyward and is oriented substantially parallel to bottom 10 of tumbler 2. Once a convertible lid and coaster 4 is inserted within the open end of a tumbler 2 in the foregoing manner, a user may align one or more convertible lid and coaster grooves 16 with one or more lugs 6 and thereafter rotate convertible lid and coaster 4 while securely holding tumbler 2, in order to removably lock convertible lid and coaster 4 into a fixed position relative to tumbler 2. It will be understood that when convertible lid and coaster 4 is removably coupled with bottom portion 10 of tumbler 2, convertible lid and coaster 4 may act as a coaster and may prevent condensation or spill damage to tabletops, countertops and the like. It will be further understood that when convertible lid and coaster 4 is removably coupled with bottom portion 10 of tumbler 2, open portion 1 (FIG. 1) of tumbler 2 may remain open.
Referring to FIGS. 4 and 5, the operation of tumbler 2 with convertible lid and coaster 4 is illustrated. Convertible lid and coaster 4 may be removably coupled either within open portion 1 of tumbler 2 or with bottom portion 10 of tumbler 2. When convertible lid and coaster 4 is removably coupled within open portion 1 of tumbler 2, top surface 22 of convertible lid and coaster 4 may be substantially flush with brim 3 (FIG. 5). Alternatively, convertible lid and coaster 4 may be removably coupled with bottom 10 of tumbler 2, as described above in the use of FIG. 3.
The operation of tumbler 2 removably coupled with convertible lid and coaster 4 illustrated in the top perspective view of FIG. 6 will now be described. A user may introduce a beverage into tumbler 2 (with convertible lid and coaster 4 removed from open portion 1 of tumbler 2). A beverage may include one or more of any of the following: a ready-to-drink beverage; constituent components of a beverage; flavor mixes, syrups or other additives; coloring; fruit; olives; vegetables; ice; seltzer; tonic water; uncarbonated water; carbonated water; a decorative item; soup, broth, consommé, or any other beverage or component thereof.
Once a user has introduced a beverage or beverage component into tumbler 2, a user may thereafter place and removably couple convertible lid and coaster 4 within open end 1 of tumbler 2 in the manner described with regard to FIG. 2, above. Additionally, a user may manipulate into an open position (and thereafter maintain the open position) securable straw hole 20, so that it may accept therethrough a drinking straw or other similar device. Alternatively, a user may manipulate into a closed position securable straw hole 20, so that it may further prevent spillage, contamination or adulteration of a beverage contained within tumbler 2. It will be understood that when securable straw hole 20 is maintained in an open position (with convertible lid and coaster 4 removably coupled within open portion 1 of tumbler 2), top surface 22 of convertible lid and coaster 4 may be in fluid communication with the interior of tumbler 2.
In places where the description above refers to particular implementations of a tumbler with convertible lid and coaster, it should be readily apparent that a number of modifications may be made without departing from the spirit thereof and that these implementations may be applied to other than tumblers with convertible lid and coasters. The accompanying claims are intended to cover such modifications as would fall within the spirit and scope of the disclosure set forth in this document. The presently disclosed implementations are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the disclosure being indicated by the appended claims rather than the foregoing description.
