Abstract
A dummy plug () is formed with only one lip () having a wide outer surface () with a fine undulated pattern () that has repeated projections () of short height. The projections () are disposed to be tangent to a plane. Inclined surfaces () are formed at opposite ends of the outer surface (). The inclined surface () guides the dummy plug () centrally into a cavity () while the outer surface () is compressed uniformly and resiliently over the entire circumference. The outer surface () closely contacts the inner surface of the cavity () due to a resilient force, thereby sealing the cavity (). The fine undulated pattern () decreases the contact area and hence decreases the frictional resistance. Thus, the dummy plug () can be inserted smoothly inserted into the cavity () with a smaller force.
