Abstract
A body portion of the funnel has a first region of dimension h, the dimension h being measured from the seal edge surface in a direction parallel to a tube axis, and a second region excluding the first region. The second region has a thickness relatively smaller than the thickness of the first region, so that a boundary portion between the two regions forms a stepped portion on the external surface of the body portion.
