<p>A combined closure and pouring spout includes a neck (14) for fitting into the filling opening of a container and a pouring spout (16) connected to the neck by an annularfrang- ible diaphragm (48). The spout (16) includes a sleeve (46) and a conical wall (28). The sleeve (46) extends into the neck (14) to guide the spout during opening of the closure. A pull ring (56) is provided which enables the spout (16) to be pulled through the neck to break the diaphragm. Elements (62) are deformed by the neck as the spout is pulled through it and thereafter engage a neck surface to prevent the spout returning to its initial position. For pouring purposes the spout )16) is pulled further through the neck to a position in which a sealing face (42) thereof engages the neck. Pouring occurs through an opening (32) and air enters through an aperture (38) and passage (36).</p> |
