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 (1) of a container and a plastics closure (2, 20) which is composed of a lower closure portion (2) with a closure foot (3), which can be fitted in an aperture of the lid (1), and a screw cap (20) which can be screwed on a pouring spout (17) of the lower closure portion (2), wherein the edge of the lid aperture is provided with an annular circumferential web (4) facing towards the outside of the lid, which is in engagement with the closure foot (3) fitted in the lid aperture, and closure foot (3) is configured U-shaped in cross-section, and grips around the web (4) with both U-arms (5, 6). 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 (1) a groove (10) surrounding the web (4) is provided, which is provided for engagement of the outer U-arm of the closure foot.
Combination of the plastics lid (1) of a container and a plastics closure (2, 20) which is composed of a lower closure portion (2) with a closure foot (3), which lower closure portion can be fitted in an aperture of the lid (1), and a screw cap (20) which can be screwed onto a pouring spout (17) of the lower closure portion (2), wherein the edge of the lid aperture is provided with an annular circumferential web (4) facing towards the outside of the lid, which is in engagement with the closure foot (3) fitted in the lid aperture, and the closure foot (3) is configured U-shaped in cross-section, and grips around the web (4) with both U-arms (5, 6), wherein on the lid (1) a groove surrounding the web (4) is provided, in which the outer U-arm of the closure foot engages, wherein the U-shaped closure foot grips around the web, characterised in that the outer U-arm of the closure engages suitably in the groove in the manner such that its lower edge is protected from external access, and in that in the region of the groove and in the region of the outer arm of the closure foot engaging in the groove, mutual engaging elements (8, 9) are provided which form a twist-proof engagement between said closure foot and said lid, thereby preventing rotation of said lower closure portion when force is applied to said screw cap.
Combination of the plastics lid (1) of a container and a plastics closure (2, 20) which is composed of a lower closure portion (2) with a closure foot (3), which lower closure portion can be fitted in an aperture of the lid (1), and a screw cap (20) which can be screwed onto a pouring spout (17) of the lower closure portion (2), wherein the edge of the lid aperture is provided with an annular circumferential web (4) facing towards the outside of the lid, said web is provided with a circumferential projection (12) projecting radially inwards, and approximately nose-shaped in cross-section, said web is in engagement with the closure foot (3) fitted in the lid aperture, and the closure foot (3) is configured U-shaped in cross-section, and grips around the web (4) with both U-arms (5,6), in which the inner arm (5) of the U-shaped enclosure foot (3) is provided with a circumferential external annular bead (4), wherein on the lid (1) a groove surrounding the web (4) is provided, in which the outer U-arm (6) of the closure foot engages, wherein the U-shaped closure foot grips around the web, characterized in that the outer U-arm of the closure engages suitably in the groove in the manner such that its lower edge is protected from external access, and in that in the region of the groove and in the region of the outer arm of the closure foot engaging in the groove, mutual engaging elements (8,9) are provided which at least limit relative twisting of the closure foot with respect to the lid.
