A lid facilitates opening a sealed container and includes a connecting rim engageable with the sealed container and encircling a lid surface, and threads disposed on an inside surface of the connecting rim. A cutting tab is disposed on the lid surface. The cutting tab is sized and positioned to engage a seal of the sealed container when the lid is threaded onto the sealed container via the threads. In one application, the lid is applied to a pre-filled container including a product sealed in the container. The lid serves to open the seal and provide access to the product.

1. A lid for opening a sealed container, the lid comprising: a connecting rim engageable with the sealed container and encircling a lid surface;threads disposed on an inside surface of the connecting rim;a drinking spout disposed offset from a center of the lid surface;a stabilizing base disposed on the lid surface surrounding the drinking spout;a circular internal rim disposed on the lid surface, the internal rim being spaced from the connecting rim by an amount sufficient to receive a top rim of the container between the internal rim and the connecting rim; anda cutting tab disposed on the lid surface, wherein the cutting tab is engaged with the stabilizing base and extends between the stabilizing base and the circular internal rim, wherein a radial distance from the center of the lid surface to the cutting tab in a plane of the lid surface varies along a length of the cutting tab such that the cutting tab is displaced across a cutting path to engage and displace a seal of the sealed container when the lid is threaded onto the sealed container via the threads. 2. A lid according to claim 1, further comprising a peel-away extension disposed adjacent an end of the connecting rim, the peel-away extension being removable and effectively extending a depth of the lid, wherein the peel-away extension is sized to prevent the cutting tab from coming in contact with the seal of the sealed container. 3. A lid according to claim 1, further comprising an air vent formed in the lid surface. 4. A lid according to claim 1, wherein the connecting rim, the threads, and the cutting tab are molded in a one-piece assembly. 5. A lid according to claim 1, wherein the drinking spout is a no-spill drinking spout. 6. A lid according to claim 1, wherein the cutting tab is rectangular. 7. A lid according to claim 1, wherein the cutting tab extends from a position adjacent the drinking spout and a first radial distance from the center of the lid surface toward the connecting rim a second radial distance from the center of the lid surface. 8. A lid according to claim 7, wherein the second radial distance is greater than the first radial distance. 9. A method of opening a sealed container using the lid of claim 2, the method comprising removing the peel-away extension, and tightening the lid on the sealed container. 10. A pre-filled container comprising: a container body having a top rim with external threads, the top rim defining a container opening;a product disposed in the container body;a seal disposed over the container opening and sealing the product in the container body; anda lid engageable with the top rim, wherein the lid comprises: a connecting rim engageable with the top rim and encircling a lid surface,threads disposed on an inside surface of the connecting rim,a drinking spout disposed offset from a center of the lid surface,a stabilizing base disposed on the lid surface surrounding the drinking spout,a circular internal rim disposed on the lid surface, the internal rim being spaced from the connecting rim by an amount sufficient to receive a top rim of the container between the internal rim and the connecting rim, anda cutting tab disposed on the lid surface, wherein the cutting tab is engaged with the stabilizing base and extends between the stabilizing base and the circular internal rim, wherein a radial distance from the center of the lid surface to the cutting tab in a plane of the lid surface varies along a length of the cutting tab such that the cutting tab is displaced across a cutting path to engage and displace the seal of the container body when the lid is threaded onto the container body top rim via the threads. 11. A pre-filled container according to claim 10, wherein the lid further comprises a peel-away extension disposed adjacent an end of the connecting rim, the peel-away extension being removable and effectively extending a depth of the lid, wherein the peel-away extension is sized to prevent the cutting tab from coming in contact with the seal of the container body. 12. A prefilled container according to claim 10, wherein the cutting tab is positioned to create an opening in the seal through which the product can be dispensed through the lid when the lid is threaded onto the container body top rim via the threads. 13. A pre-filled container according to claim 10, wherein the drinking spout is a no-spill drinking spout. 14. A method of manufacturing a lid for opening a sealed container, the method comprising: (a) forming a connecting rim engageable with the sealed container, the connecting rim encircling a lid surface;(b) providing threads on an inside surface of the connecting rim;(c) forming a drinking spout positioned offset from a center of the lid surface;(d) forming a stabilizing base on the lid surface surrounding the drinking spout;(e) disposing a circular internal rim on the lid surface, the internal rim being spaced from the connecting rim by an amount sufficient to receive a top rim of the container between the internal rim and the connecting rim; and(f) forming a cutting tab on the lid surface in engagement with the stabilizing base and extending between the stabilizing base and the circular internal rim, the forming step being practiced such that a radial distance from the center of the lid surface to the cutting tab in a plane of the lid surface varies along a length of the cutting tab and such that the cutting tab is displaced across a cutting path to engage and displace a seal of the sealed container when the lid is threaded onto the sealed container via the threads. 15. A method according to claim 14, wherein steps (a)-(e) are practiced by molding the connecting rim, the threads, the drinking spout, the stabilizing base, and the cutting tab in a one-piece assembly. 16. A method according to claim 15, wherein the lid is constructed of plastic, and wherein the molding step comprises injection molding.
