If the projection is formed on the entire circumference of the projection 18, the opening piece portion including the projection 18 separates from the plate 17, which is the lid body, and falls into the container. It is evident that, if the part is only part of the periphery of the projection, only that part is torn open, and the opening piece still remains in a state of being disconnected from the lid body.
  • the convex portion is not a flat plate must be formed, firstly, the pushing force is used as the shearing force of the cutting guide line 19.
  • the pressing force When simply forming a cutting guide line on a flat plate and pressing the opening surrounded by it, the pressing force is decomposed into shearing force and tensile force of the thin plate, and the effect is reduced, but the protrusion is reduced. If it is formed, the pushing force acts on the cutting guide line as a shearing force as it is through the side wall of the projection.

Therefore, in this case, when the flat surface 58 of the convex portion 57 is pressed, the pressing force is more effective as the rising angle of the side wall 60 of the convex portion 57 from the lid body 59 becomes closer to vertical, and the local five-part tearing occurs. I will guide you. As shown in the figure, the dehiscence starts at about 61 at the cutting guide line. When the rupture is locally performed in this manner, this type of cutting guide line is subsequently ruptured by a very strong pressing force, which is advantageous in reducing the maximum pressing force. .
