A one-piece dispensing closure for dispensing essential oils includes an integrally formed closure body, tubular dispensing spout, a hinged cap, a tamper-evident closure system and a latch for maintaining the cap in an open position. The cap is connected to the closure body by a living hinge to allow the user to selectively open and close the container. A tamper-evident tear strip is integrally formed with the closure body. A locking tab on the cap engages a shoulder on the tear strip to prevent opening of the cap without removing the tear strip.
