• and
• said self-sealing liner including an exposed target surface and a deformable interior surface facing toward said pierceable membrane to one side of said parting line, said deformable interior surface defining a recess aligned with said exposed target surface and providing an inwardly enlarging passageway for a piercing spike while supplying increased resistance against removal of said piercing spike when inserted through said target surface.
