ABSTRACT:
A hermetically sealed container formed from thermoplastic material is provided with a hollow body having an open end terminating in a tapered wall defining a sealing region about an opening with a decreasing cross-sectional area in the direction toward the interior of the hollow body. A hollow plug insert is provided in the opening and has a peripheral sealing surface generally complementary with the defined sealing region. Over the opening is a closure structure that is unitary with the hollow body, that encloses the plug insert, and that retains the plug insert in the opening. A severable frangible web joins the closure structure to the hollow body outwardly of the opening.
