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.

A dispenser for dispensing a fluid from a container, the dispenser comprising:
- an inlet for connecting to the container so as to receive the fluid therethrough;
- and,
- an outlet comprising at least two walls each with a respective slit 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;
- a respective support region between and integral with at least one pair of walls positioned away from the slits and arranged so as to bias the slits towards a closed condition when no pressure is applied to the fluid.
A dispenser for dispensing a fluid from a container, the dispenser comprising:
- an inlet for connecting to the container so as to receive the fluid therethrough;
- and,
- an outlet comprising at least two upstanding intersecting walls each with a respective slit on a distal end thereof 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 respective support region between and integral with at least one pair of walls positioned away from the slits and arranged so as to bias the slits towards a closed condition when no pressure is applied to the fluid.
A dispenser for dispensing a fluid from a container, the dispenser comprising:
- a first resilient part having an inlet so as to receive the fluid therethrough;
- and,
- a second elastomeric part having an outlet 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, wherein the second part comprises two or more walls each with a respective slit thereon to provide the opening;
- a respective support region between and integral with at least one pair of walls positioned away from the slits and arranged so as to bias the slits towards a closed condition when no pressure is applied to the fluid.
A dispenser for dispensing a fluid from a container, the dispenser comprising:
- a first resilient part formed from a first material and having an inlet so as to receive the fluid therethrough;
- and,
- a second elastomeric part formed from a second material and having an outlet 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 wherein the first material and the second material are incompatible.
