Abstract
A rubber plug for a vial container containing medicinal chemicals according to the present invention can be smoothly conveyed by a part feeder while preventing each other's adhesion. The top surface of a discoid cap portion 1A has a Shore A hardness of 25-55 and a surface roughness Ra of 2.5-10.5 μm. Adherence of the top surface of the discoid cap portion 1A is reduced by synergy effect. The rubber plug 1 can be smoothly conveyed by a part feeder in an inverted position which turns the top surface of the discoid cap portion to the conveying surface.
