Abstract
Plastic snap-on hinged closures each having a bottom part and a cap that are attached to each other by a snap-on hinge tend to tear on the lateral borders. This is due to the geometry of closures having a round or oval shape when viewed from the top since only the flexibility of the outer walls have been used so far. This unresolved problem can be solved by a curvature with varying height and wall thickness extending along the joint. The curvature is elastic when pressure is exerted in the middle and when pulled from the sides.
