Container pour spout with peelable tamper-proof seal

摘要

A container having an externally threaded pour spout on which an internally threaded cap is screwed. A tamper-proof, removable, membrane-like or diaphragm-like closure for the spout is secured to the circumferential lip of the spout with a peelable seal. The membrane-like closure has an elongated pull tab extending therefrom, by pulling on which the closure may be peeled off the end of the spout. The external threads on the spout are interrupted so as to provide a groove in which the pull tab resides out of engagement or interference with the external and internal threads on the spout and cap.
