A reclosable cup lid thermoformed from a polymeric material. The lid includes a closure panel and a lid member having a sidewall and a top wall. The top wall can have an upper and lower side and a drinking aperture at a periphery of the top wall. The top wall can define a pair of engagement tracks disposed on the lower side of the top wall. The engagement tracks can include a scalloped configuration and an undercut depth. The closure panel can be insertable into the scalloped engagement tracks by application of a bending force to the lid member suitable to widen the distance between the tracks.

What is claimed is: 1. A reclosable and disposable lid for a cup comprising: a thermoformed lid member comprising: a sidewall suitable for engagement with a cup brim; and a top wall having an upper and a lower side wherein the top wall comprises: a drinking aperture at a periphery of the top wall;

What is claimed is: 1. A reclosable and disposable lid for a cup comprising: a thermoformed lid member comprising: a sidewall suitable for engagement with a cup brim; and a top wall having an upper and a lower side wherein the top wall comprises: a drinking aperture at a periphery of the top wall; a pair of generally parallel engagement tracks separated by a distance, wherein the tracks are disposed in a longitudinal direction on the lower side of the top wall, wherein each of the tracks comprises a scalloped configuration and an undercut depth; and a post aperture opening at an end of the lid member in a direction opposite of the drinking aperture; and a thermoformed closure panel having a post and a top surface and a bottom surface, wherein the closure panel is insertable into the scalloped engagement tracks by application of a bending force to the lid member suitable to widen the distance between the tracks, thus allowing the closure panel to be inserted into the scalloped engagement tracks such that the post projects upwardly through the post aperture opening, wherein at least one vent hole is present in either or both of the lid member or the closure panel, and wherein the closure panel comprises a reservoir suitable to collect beverage leakage into the scalloped engagement track area from a container engaged with the reclosable cup lid. 2. The lid of claim 1, wherein the scalloped engagement tracks do not comprise C-shaped rails. 3. The lid of claim 1, wherein one of the at least one vent hole is located within a boundary of the reservoir on the closure panel, and wherein one of the at least one vent hole has a barb extending from the bottom surface of the closure panel. 4. The lid of claim 1, wherein at least one vent hole is present in the lid member and comprises a barb extending from the upper side of the top wall, and wherein at least one vent hole is present in the closure panel and comprises a barb extending from the bottom surface of the closure panel. 5. The lid of claim 1, wherein the closure panel comprises a panel locking contour in a position forward of the post aperture, the lid member comprises a lid member locking contour, wherein the locking contours are configured to cooperate, thereby providing a locking mechanism in the lid to substantially prevent the closure panel from opening without engagement by a user. 6. The cup lid of claim 5, wherein the closure member locking contour has a height of from about 0.020 to about 0.040 inches. 7. The lid of claim 1, wherein the reservoir comprises a vent hole within the boundary of the closure panel. 8. A reclosable and disposable lid for a cup comprising: a thermoformed lid member comprising =a sidewall suitable for engagement with a cup brim; and a top wall having an upper and a lower side wherein the top wall comprises: a drinking aperture at a periphery of the top wall; a post aperture opening; a top wall locking contour; and a first vent hole having a first barb extending from the upper side of the top wall; and a thermoformed closure panel comprising: a post projecting upwardly from the panel, wherein the post is configured to project upwardly through the post aperture opening; a reservoir suitable for collection of liquid contained within a container, where such liquid is retained in the area of the closure panel as a result of spillage during transport or consumption of the beverage from the container; a second vent hole having a second barb extending from a bottom side of the closure panel; and a closure panel locking contour configured to cooperate with the top wall locking contour wherein the respective locking contours cooperate to provide locking of the closure panel member so as to substantially prevent opening of the closure panel without operation by a user, wherein the locking mechanism allows the closure panel to be opened by a user with substantially one handed operation, and wherein the vent holes are not in substantial alignment in the reclosable cup lid when the lid is either in an open or a closed position. 9. The lid of claim 1, wherein one of the at least one vent hole is located within the reservoir. 10. The lid of claim 8, wherein the second vent hole is located within a boundary of the reservoir. 11. The lid of claim 8, wherein the closure panel locking contour has a height of from about 0.020 to about 0.040 inches. 12. A lid for a cup, comprising: a thermoformed lid member comprising: a top wall having an upper side and a lower side; a pair of engagement tracks disposed on the lower side of the top wall, wherein each of the engagement tracks comprises a scalloped configuration and an undercut depth; a first aperture disposed through the top wall; and a second aperture disposed through the top wall; and a thermoformed closure panel disposed within the engagement tracks of the lid member, the closure panel comprising: a post projecting through the first aperture, wherein the post is adapted to move the closure panel between an open position and a closed position, and wherein the closure panel covers the second aperture in the closed position; a reservoir; and at least one vent hole disposed in at least one of the lid member and the closure panel. 13. The lid of claim 12, wherein the scalloped engagement tracks are not C-shaped. 14. The lid of claim 12, wherein the at least one vent hole is located within a boundary of the reservoir on the closure panel, and wherein the at least one vent hole has a barb extending from a bottom side of the closure panel. 15. The lid of claim 12, wherein the at least one vent hole is formed in both the lid member and the closure panel, wherein a lid member vent hole has a barb extending from the upper side of the top wall, and wherein a closure panel vent hole has a barb extending from a bottom side of the closure panel. 16. The lid of claim 12, wherein: the closure panel comprises a panel locking contour in a position forward of the post aperture, the lid member comprises a lid member locking contour, and the locking contours are configured to cooperate, thereby providing a locking mechanism in the lid to substantially prevent the closure panel from opening without engagement by a user. 17. The cup lid of claim 16, wherein the closure member locking contour has a height of from about 0.020 to about 0.040 inches. 18. The lid of claim 12, wherein the closure panel has chamfered longitudinal edges. 19. The lid of claim 18, wherein the chamfered longitudinal edges have a chamfer angle of from about 5 to about 15 degrees with respect to an upper surface of the closure panel. 20. The lid of claim 12, wherein the undercut depth is of from about 0.02 to about 0.06 inches.
