A drink-through lid with spill resistant tab for use on a beverage container. The lid provides a drink outlet that allows liquid to fill a drink well base, from which a consumer may sip a beverage similar to using a cup. The lid is provided with a spill resistant tab. The tab may include a blade portion which fits through a slit in the drink-through lid. The blade extends outward to a distal blade edge adjacent an interior wall of the beverage container. The blade has a width W2 as wide or wider than the effective outlet width W1 of the drink outlet. The lid may be provided with a generally V-shaped groove having a slit at the bottom thereof for passage of the blade therethrough. In an embodiment, the tab may include a Z-shaped connector portion sized and shaped for interlocking mating engagement with the V-shaped grove.

1. A drink-through lid for a beverage cup having an open end, comprising: a base comprising a rim having a bottom edge, and an interior bead sealing portion, said base sized and shaped to sealingly engage the open end of the beverage cup;a raised lip portion having an exterior portion extending upwardly from said base, an outer lip portion, and an interior portion sloping downwardly from said outer lip portion to lower end portions;a drink well base having a floor extending from a peripheral side adjacent said lower end portions, the drink well base located downward from said outer lip portion, said drink well having an underside;at least one drink outlet, said at least one drink outlet defined by a first edgewall extending upward into said interior portion of said raised lip portion and by an elongated second edgewall of effective opening width W1 extending along an outlet portion of said drink well base, said at least one drink outlet oriented at least in part as if along a first surface extending from said elongated second edgewall substantially at an angle alpha (α) in the range of from about forty-five degrees (45°) to about ninety degrees (90°), so that said at least one drink outlet is substantially vertically oriented;a downwardly extending valley shaped wall, said valley shaped wall comprising first and second sidewalls extending across at least a portion of said lid, and a slit of length LS between said first and second sidewalls;a spill resistant tab, said spill resistant tab comprising a blade portion, a handle portion, and a connector portion between said blade portion and said handle portion, said blade portion sized and shaped to fit through said slit, said blade portion secured in a working position below said underside of said drink well adjacent said at least one drink outlet, said blade portion having a width W2 sufficient to resist movement of liquid outward through said at least one drink outlet; andwherein said blade portion is sized, shaped, and positioned to resist splash of liquid from inside the beverage cup toward said at least one drink outlet, while allowing liquid to flow around said blade portion to said at least one drink outlet before escaping to said drink well base. 2. A drink-through lid as set forth in claim 1, wherein said valley shaped wall comprises a V-shaped wall. 3. A drink-through lid as set forth in claim 1, wherein said beverage cup has an interior wall, and wherein said blade portion comprises a distally located blade edge sized and shaped for close fitting engagement near or with said interior wall. 4. A drink through lid as set forth in claim 3, wherein said bladed edge comprises a smooth radiused edge. 5. A drink through lid as set forth in claim 4, wherein said smooth radiused edge has a radius of curvature along a radius of 1.620 inches. 6. A drink-through lid as set forth in claim 1, wherein said at least one drink outlet has an effective opening width W1 of about 1.0 inches. 7. A drink-through lid as set forth in claim 1, or in claim 6, wherein said blade portion has a width W2 of about 1.5 inches. 8. A drink-through lid as set forth in claim 1, wherein said blade portion of said spill resistant tab is substantially planar. 9. A drink-through lid as set forth in claim 1, wherein said blade portion comprises substantially planar portions and one or more stiffening ribs. 10. A drink-through lid as set forth in claim 1, wherein said handle portion of said spill resistant tab is substantially planar. 11. A drink-through lid as set forth in claim 1, wherein said handle portion of said spill resistant tab comprises a substantially planar portion, and an upwardly extending ear portion. 12. A drink-through lid as set forth in claim 1, wherein said connector portion of said spill resistant tab is substantially planar. 13. A drink-through lid as set forth in claim 1, wherein said connector portion of said spill resistant tab comprises a substantially planar central portion. 14. A drink-through lid as set forth in claim 13, wherein said connector portion further comprises a pair of stiffening panels, one of said stiffening panels located along each of first and second sides of said connector portion. 15. A drink-through lid as set forth in claim 1, wherein said blade portion comprises a substantially planar blade proximal portion adjacent said connector portion, and wherein said blade proximal portion, and said connector portion are joined at a first hinge fold having an angle delta. 16. The drink-through lid as set forth in claim 15, wherein said angle delta of said first hinge fold is in a range of from about 55 to about 75 degrees. 17. The drink through lid as set forth in claim 15, wherein said angle delta of said first hinge fold is in a range of from about 60 to about 70 degrees. 18. A drink-through lid as set forth in claim 1, wherein said handle portion comprises a substantially planar handle proximal portion adjacent said connector portion, and wherein said handle proximal portion and said connector portion are joined at a second hinge fold having an angle phi. 19. The drink-through lid as set forth in claim 18, wherein said angle phi of said second hinge fold is in a range of from about 40 to about 60 degrees. 20. The drink through lid as set forth in claim 19, wherein said angle phi of said second hinge fold is in a range of from about 45 to about 55 degrees. 21. The drink-through lid as set forth in claim 1, wherein said blade portion width W2 is equal to or larger than said effective opening width W1. 22. The drink-through lid as set forth in claim 1, wherein said blade portion width W2 is larger than said effective opening width W1 by about 0.25 inches, or more. 23. The drink-through lid as set forth in claim 1, wherein said blade portion width W2 is larger than said effective opening width W1 by about 0.5 inches, or more. 24. The drink-through lid as set forth in claim 1, wherein said connector portion of said spill resistant tab is sized and shaped for secure mating engagement with at least a portion of said valley shaped wall, wherein said spill resistant tab is secured to allow drinking from said beverage cup while providing resistance to liquid flow through said at least one drink outlet. 25. The drink-through lid as set forth in claim 1, wherein said spill resistant tab has a Z-shaped profile, as examined in vertical cross-section, between said blade portion and said handle portion. 26. The drink-through lid as set forth in claim 25, wherein said connector portion of said spill resistant tab is sized and shaped for close fitting engagement with said downwardly extending valley shaped wall, wherein said spill resistant tab is secured to allow drinking from a beverage cup while providing resistance to liquid flow through a drink outlet in a drink-through lid.
