Other than the exemplary structural techniques just taught above for facilitating manufacture of lid designs 30 and 39 as taught herein, the processes for manufacturing such goods are well known in the art, and thus will not be further explained herein. However, those skilled in the art will recognize that various embodiments may be manufactured using other processes, and consequently, the invention is not limited to any particular method of manufacture.

[0068] In the foregoing description, for purposes of explanation, numerous details have been set forth in order to provide a thorough understanding of the disclosed exemplary embodiments for the design of a disposable lid with spill resistant tab for use in combination with a beverage container. However, certain of the described details may not be required in order to provide useful embodiments, or to practice selected or other disclosed embodiments. Further, for descriptive purposes, various relative terms may be used. Terms that are relative only to a point of reference are not meant to be interpreted as absolute limitations, but are instead included in the foregoing description to facilitate understanding of the various aspects of the disclosed embodiments. And, various actions or activities in any method described herein may have been described as multiple discrete activities, in turn, in a manner that is most helpful in understanding the present invention. However, the order of description should not be construed as to imply that such activities are necessarily order dependent. In particular, certain operations may not necessarily need to be performed precisely in the order of presentation. And, in different embodiments of the invention, one or more activities may be performed simultaneously, or eliminated in part or in whole while other activities may be added. Also, the reader will note that the phrase in an embodiment or in one embodiment has been used repeatedly. This phrase generally does not refer to the same embodiment; however, it may. Finally, the terms comprising, having and including should be considered synonymous, and open ended, and thus should be interpreted to mean including, but not limited to, unless the context expressly dictates otherwise.

[0069] From the foregoing, it can be understood by persons skilled in the art that a novel beverage container lid, and spill resistant tab for use with a beverage container lid, have been described herein. Although only certain specific embodiments of the present invention have been shown and described, there is no intent to limit this invention by these embodiments. Rather, the invention is to be defined by the appended claims and their equivalents when taken in combination with the description.

[0070] Importantly, the aspects and embodiments described and claimed herein may be modified from those shown without materially departing from the novel teachings and advantages provided, and may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. More generally, drink-through lid designs with spill resistant tabs, whether or not including a precisely V-shaped groove with slit for accommodation of a spill resistant tab, may be configured using the teaching hereof, and are thus intended to be included with the breadth of appropriate claims as set forth below. Therefore, the embodiments presented herein are to be considered in all respects as illustrative and not restrictive or limiting. As such, this disclosure is intended to cover the structures described herein and not only structural equivalents thereof, but also equivalent structures.

[0071] Numerous modifications and variations are possible in light of the above teachings. Therefore, the protection afforded to this invention should be limited only by the claims set forth herein, and the legal equivalents thereof.
