A spout is disclosed, for insertion into and securement to a plastic pouch. The spout comprises a tube (11) having a piercing portion (13) separated from a delivery portion (12) by a film securement portion (22) and having fluid flow communication from the piercing portion to the delivery portion. The film securement portion (22) is adapted to secure, with a substantially liquid-tight seal, plastic film which has been pierced by the piercing portion. The piercing portion (13) appears, in one perspective, to have been sliced at an angle to the longitudinal axis from a first location (23) at one side of said tube adjacent the film securement portion to a second location (14) at the other side of the tube, distal from the film securement portion, to form a tip (14) and to provide a slot (25) which aims to aid in draining material from the pouch, and the tip appears, in a second perspective perpendicular to the first perspective, to have been sliced symmetrically about the longitudinal axis of the tube to form a pointed piercing tip furthest away from the film securement portion (22). The contours of these slices are such that when the pointed tip (14) is pushed into the film, the force required remains substantially constant. |
