Abstract: A dispenser (10) for dispensing a fluid from a container T comprises an inlet (14) for connecting to the container so as to receive the fluid therethrough, and an outlet (16). The outlet comprises at least two walls (18), each with a respective slit (22) thereon adapted to open to release fluid therefrom when a predetermined pressure is applied to the fluid in the dispenser at the outlet, and to close to retain fluid in the dispenser at a pressure less than the predetermined pressure.

Abstract: A dispenser for dispensing a fluid from a container T having an inlet for mounting to the container so as to receive therethrough the fluid, and an outlet which is adapted to open to release fluid therefrom when a predetermined pressure is applied to the fluid in the dispenser at the outlet, and to close to retain fluid in the dispenser at a pressure less than the predetermined pressure. A wall of resilient material at the outlet has one or more panels of elastomeric material provided therein, each panel being deformable to enable the adjacent resilient material to flex at the predetermined pressure and thus enable the outlet to open.
