The top part of the side (2) of the can (1) is truncated cone-shaped around which runs a neck made of material which is not, or only slightly, expandable and is easily torn at least at one point. The top inner diameter of the neck is smaller than the outer diameter of the flanged edge (3) of the lid.(4). The crimped neck (6) is made of coated paper, cardboard, textile, metal foil or a laminate. |
