Abstract

The diameter of the external and/or internal surface in the edge side of the neck portion which connects for the funnel portion gradually expands to the edge. Then, the expansion rate of the part located in the open end vicinity (the edge side) was decreased in this expansion part. By this, the V character groove is avoided between stem dowel and neck portion inwall, and the swelling of the external wall in the flare shape division in the sealing portion vicinity is prevented.
