A disposable beverage container lid that includes a top wall with a drinking opening formed therein, an annular sidewall downwardly depending from the periphery of the top wall for engaging with the rim of a beverage container, a regulator valve formed directly underneath the drinking opening, and wave-breaker and periphery inhibitor recesses formed in the top wall, to allow the user to drink from the cup without removing the lid while greatly minimizing accidental splashing of the liquid from the cup. The regulator valve includes side and bottom walls with apertures formed therein. The wave-breaker recess has a sidewall portion that reflects waves of liquid from the regulator valve, and another sidewall portion that defines a channel with the annular sidewall in which the regulator valve is disposed. The inhibitor recesses extend down into the channel to prevent waves of liquid traveling therethrough.

1. A lid for covering a drinking cup containing a liquid, comprising:a top wall having a generally circular periphery;an annular sidewall downwardly depending from the top wall periphery;the lid including a drinking opening formed adjacent to the periphery;a regulator valve formed under the drinking opening, the regulator valve including:a first sidewall structure downwardly depending from the lid adjacent the drinking opening and terminating in a first bottom wall;a plurality of apertures formed in at least one of the first sidewall structure and the first bottom wall, wherein any of the plurality of apertures formed in the first sidewall structure are positioned in an opposing manner;a second opening formed in the first bottom wall;a second sidewall structure downwardly depending from the first bottom wall adjacent to the second opening and terminating in a second bottom wall; andat least one aperture formed in one of the second bottom wall and the second sidewall structure.2. The lid of claim 1, wherein the plurality of apertures are formed in the first bottom wall and the at least one aperture is formed in the second bottom wall.3. The lid of claim 1, wherein the plurality of apertures are formed in the first bottom wall and the at least one aperture is formed in the second sidewall structure.4. The lid of claim 1, wherein the plurality of apertures are formed in the first sidewall structure and the at least one aperture is formed in the second bottom wall.5. The lid of claim 1, wherein each of the plurality of apertures has a size that is smaller than that of the drinking opening.6. The lid of claim 1, wherein the drinking opening is formed in the top wall.7. The lid of claim 1, wherein the annular sidewall includes an annular recess for receiving a rim of the cup in a liquid tight manner.8. A lid for covering a drinking cup containing a liquid, comprising:a top wall having a generally circular periphery;an annular sidewall downwardly depending from the top wall periphery;the lid including a drinking opening formed adjacent to the periphery;a wave-breaker recess formed in the top wall having a sidewall that extends downwardly, wherein the wave-breaker recess sidewall includes a first portion facing toward the drinking opening and a second portion facing away from the drinking opening, and wherein the recess sidewall second portion is non-linear for reflecting waves of the liquid away from the drinking opening;a regulator valve formed under the drinking opening, the regulator valve including:a first sidewall structure downwardly depending from the lid adjacent the drinking opening and terminating in a first bottom wall;a plurality of apertures formed in at least one of the first sidewall structure and the first bottom wall;a second opening formed in the first bottom wall;a second sidewall structure downwardly depending from the first bottom wall adjacent to the second opening and terminating in a second bottom wall; andat least one aperture formed in one of the second bottom wall and the second sidewall structure.9. The lid of claim 8, wherein the plurality of apertures are formed in the first bottom wall and the at least one aperture is formed in the second bottom wall.10. The lid of claim 8, wherein the plurality of apertures are formed in the first bottom wall and the at least one aperture is formed in the second sidewall structure.11. The lid of claim 8, wherein the plurality of apertures are formed in the first sidewall structure and the at least one aperture is formed in the second bottom wall.12. A lid for covering a drinking cup containing a liquid, comprising:a top wall having a generally circular periphery;an annular sidewall downwardly depending from the top wall periphery;a drinking opening formed in the top wall adjacent to the periphery;a regulator valve formed under the drinking opening, the regulator valve including:a first sidewall structure downwardly depending from the top wall adjacent the drinking opening and terminating in a first bottom wall,a second opening formed in the first bottom wall,a second sidewall structure downwardly depending from the first bottom wall adjacent to the second opening and terminating in a second bottom wall,a plurality of apertures formed in the first bottom wall, andat least one aperture formed in the second bottom wall; anda wave-breaker recess formed in the top wall having a sidewall that extends downwardly, wherein the wave-breaker recess sidewall includes a first portion facing toward the regulator valve and a second portion facing away from the regulator valve, and wherein the recess sidewall second portion has one of a concave and a convex shape for reflecting waves of the liquid away from the regulator valve.13. The lid of claim 12, wherein:the wave-breaker recess sidewall first portion faces but is separated from the annular sidewall to form a channel therebetween,the regulator valve is disposed in the channel, andthe lid further comprises a plurality of inhibitor recesses formed in the top wall that downwardly extend into the channel for blocking waves of the liquid traveling along the channel.14. The lid of claim 12, wherein the wave-breaker recess extends downwardly further from the periphery than does the regulator valve.15. A lid for covering a drinking cup containing a liquid, comprising:a top wall having a generally circular periphery;an annular sidewall downwardly depending from the top wall periphery;the lid including a drinking opening formed adjacent to the periphery; anda regulator valve formed under the drinking opening, the regulator valve including:a first sidewall structure downwardly depending from the lid adjacent the drinking opening and terminating in a first bottom wall;a first aperture formed in the first sidewall structure or the first bottom wall;a second opening formed in the first bottom wall;a second sidewall structure downwardly depending from the first bottom wall adjacent to the second opening and terminating in a second bottom wall; anda second aperture formed in the second bottom wall and or second sidewall structure.16. The lid of claim 15, wherein the first aperture is formed in the first bottom wall and the second aperture is formed in the second bottom wall.17.
