Abstract
A closure () is provided to selectively permit or restrict communication between the exterior and the interior of a system that has an opening between the exterior and interior. The closure () includes a closure body () that defines an access passage () and a membrane () that initially occludes the access passage (). The connection of the membrane () to the body () is defined by a tearable portion () of material that defines a tear path along which the material can be torn. The tear path has; (A) a first separation path () where separation of the membrane () from the body () initially originates; and (B) a second separation path () where separation of the membrane () from the body () terminates. The second separation path () has a generally tapered configuration.
