Abstract

PURPOSE: To reduce the decrease in strength of the central part of an outer blade and decrease of the cutting quality accompanying with its deformation by forming the diameter of the blade holes at the central part of a dorm state outer blade having many pill-introducing blade holes as small, and the diameter of the blade holes at outer peripheral parts as large. CONSTITUTION: This blade for a pill-removing tool is provided by arranging and installing an outer blade 41 having many pill-introducing blade holes and an inner blade 42 making a contact with the outer blade 41 and sliding, forming the diameter of the blade holes 53 in the central part of the outer blade 41 having a dorm state as small and the diameter of the blade holes 53 at the peripheral parts as large. Further, by constituting the blades so as to have a relationship of the diameter of the outer blade 53 (D mm) with the blade thickness of the outer blade 41 (T μm) as 278D-430<=T<=278D-330, the reduction of strength at the central part having a large contacting pressure with a cloth, etc., becomes small, the deformation of the outer blade 41 is small, the reduction of cutting quality accompanying with the deformation can be suppressed at its minimum, and the introduction and cutting rate of the pill is not reduced, because the diameter of the blade hole 53 is large at the outer peripheral part where the relative speed with the inner blade is large.
