Notch blade, processing device, notch forming device, and notch forming method

摘要

A notching-blade plate (85) is used which positions the center axis of a product guide part (87) and the center axis of a notching blade (85B) along the same axis. When the product guide part (87) is inserted into the storage recess (24) of a container body (2) and contacts the inner surface of the storage recess (24), an automatic eccentricity guide part (81) moves the notching-blade plate (85) in the horizontal direction, and the position of the notching blade (85B) is determined so as to be coaxial with the opening (24A) of the container body (2).
