A one-piece dispensing closure for a pouch-like container includes an integrally formed closure body, dispensing neck, hinged cap, a tamper-evident closure system and a latch for maintaining the cap in an open position. The closure body includes a “canoe”-shaped skirt portion which is heat sealed to a film-like pouch and a neck portion having a dispensing orifice for dispensing a product from the pouch. A cap is connected to the closure body by a living hinge to allow the user to selectively open and close the container. The dispensing closure further includes a tamper-evident tear strip that is integrally formed with the cap body, and detachable from the cap body. A ledge formed on the inner surface of the tear strip engages an interfitting locking tab formed on the outer surface of the closure body to prevent opening of the cap without removing the tear strip.
