Plastic closure member with flowed-in liner

摘要

This relates to a closure member for containers wherein products are packaged under pressurized conditions. The closure member has a flowed-in liner, and in order to prevent relative movement between the liner and the closure member of the closure assembly, there is provided an interlock between the base of the liner and the base of a channel in which the liner is formed. This abstract forms no part of the specification of this application and is not to be construed as limiting the claims of the application.
