Abstract | Disclosed herein are closures that are formed via an injection molding process with a thin breakable web. When they are first placed in a fluid conduit and exposed to line pressure the web will break open so as to thereby create a duckbilled type check valve. Thus, the closure can provide a seal during long-term storage prior to use. However, once used it functions as a check valve. |
