Abstract (en)
[origin: WO9615036A1] Proposed is an improvement in the shape of a fold in a tin can which will allow the use of sheet metal of lower gauge than that currently used. This is achieved with a fold geometry on a tin can which is closed off with a double fold, such as a drink or food tin; by providing a continuous or stepped contour (23) on the fold side (2c, 2b); and by ensuring that the lid hook (2a, 2b, 2c) is clearly in area-contact (positive fit) on its outer side with the free end of the body hook (1a) in its lower third. The invention, if applied to standard-gauge sheet metal, results in a better seal owing to greater clamping and locking force (2d, 21). Overall, the invention results in a stronger fold.
