PROBLEM TO BE SOLVED: To provide a seal breaker for tearing and opening seals of compact multiple-containers of which openings are near to each other, by pressing the seal breaker along edges of the openings, capable of minimizing trouble generated when the seals cannot be properly torn and opened.SOLUTION: The seal breaker includes: multiple cusped bodies each having, at a tip, a polygonal pyramid shaped blade part having at least three ridge lines; a fixing member for fixing the multiple cusped bodies so that pressing the multiple cusped bodies along edges of openings of multiple-containers simultaneously tears and opens seals sealing the multiple openings of the multiple-containers; and drive means capable of driving the fixing member so as to be movable in a vertical direction. The fixing member fixes the multiple cusped bodies so that, with respect to a straight line connecting axes of the adjacent cusped bodies among the multiple cusped bodies, the sum of a minimum angle between the straight line and the ridge lines of the blade part of one of the adjacent cusped bodies and a minimum angle between the straight line and the ridge lines of the blade part of the other of the adjacent cusped bodies is equal to or over 45 degrees, when viewed from an axial direction of the cusped bodies. |
