The present invention relates to a plastics lid of a container with a plastics closure fitted in an aperture of the lid, in particular a combination of the plastics lid ( ) of a container and a plastics closure ( ) which is composed of a lower closure portion ( ) with a closure foot ( ), which can be fitted in an aperture of the lid ( ), and a screw cap ( ) which can be screwed on a pouring spout ( ) of the lower closure portion ( ), wherein the edge of the lid aperture is provided with an annular circumferential web ( ) facing towards the outside of the lid, which is in engagement with the closure foot ( ) fitted in the lid aperture, and closure foot ( ) is configured U-shaped in cross-section, and grips around the web ( ) with both U-arms ( ). In order to design a closure substantially only in two parts in combination with a lid such that in spite of a simple design, it offers a high degree of protection against tampering, furthermore the closure sealing capability is also guaranteed even under very rough transportation conditions, and in use the closure has a reliable functioning capability, it is proposed according to the invention that on the lid ( ) a groove ( ) surrounding the web ( ) is provided, which is provided for engagement of the outer U-arm of the closure foot.
