Abstract
A one-piece dispensing closure (10) for a pouch-like container (13) includes an integrally formed closure body (11), dispensing neck (30), hinged cap (20), a tamper-evident closure system (40) and a latch (62) for maintaining the cap (20) in an open position. The closure body (11) includes a “canoe”-shaped skirt portion (14) with opposing skirt walls (17,19) which are heat sealed to a film-like pouch (13) and a neck portion (30) having a dispensing orifice (34). The closure body (11) may further include reinforcing ribs (21) extending transversely between the skirt walls (17, 19) to provide support while the pouch is heat sealed to the skirt. A cap (20) is connected to the closure body (11) by a living hinge (26) to allow the user to selectively open and close the container. A tamper-evident tear strip (40) may be integrally formed with the neck portion (30). A locking tab (50) on the cap (20) engages a shoulder (42) on the tear strip (40) to prevent opening of the cap (20) without removing the tear strip (40). The closure (10) may include a liner (102) sealed over the dispensing orifice (34)
