Abstract (en)
[origin: EP0425401A1] The invention relates to a cover for a leaktight container which can be opened along a line of least resistance, by simple pulling, of the type comprising a fold (4) forming an angle which is substantially a right angle and constituting the said line of least resistance, characterised in that it is produced by stamping a sheet of steel of a thickness less than or equal to 0.16 mm. The line of least resistance permits the total or partial opening of the container. <??>The cover is preferably made from steel of a thickness of 0.10 to 0.16 mm and, at the level of the fold (4), the inner radius of curvature of the cover is from 10 to 50 mu m and the outer radius of curvature of the cover is from 100 to 200 mu m. <??>The invention applies to leaktight metal containers, such as ''beverage'' foodstuff cans or tray-type containers for precooked dishes. <IMAGE>
