PROBLEM TO BE SOLVED: To provide a cutting edge processing pin, a cutting edge manufacturing method and a container with a cutting edge, capable of separating only the cutting edge from a container body without becoming bulky, by reducing a variation in tearing strength from the respective container bodies of a plurality of container installing parts in one cutting edge, in the present invention.SOLUTION: The cutting edge processing pin 1 comprises a cut-raised piece forming shaft part 3. The cut-raised piece forming shaft part 3 comprises four surfaces formed so that a pair of mutually opposing opposed surfaces can be formed by two sets in a cross section, that is, the four surfaces 31-34 arranged so that the mutual width lengths L1 are the substantially same, and the adjacent two surfaces become vertical, and a distance L2 of the mutual two sets of opposed surfaces mutually becomes the substantially same. The four surfaces 31-34 are constituted so that the ratio L2/L1 of the width length L1 and the distance L2 of the opposed surface becomes 1.6-5.0. |
