Patent ID: 8770449

Claim:
A dispenser and container combination for dispensing a fluid; the container arranged for containing the fluid, the container comprising a portion that is able to be displaced to apply pressure to the fluid contained in the container; the dispenser comprising: a first resilient part having an inlet for connecting to the container so as to receive from the container the fluid under pressure therethrough; and, a second elastomeric part having an outlet comprising at least two upstanding walls extending from the first resilient part, each wall having a respective slit on a distal end thereof adapted to open to release fluid therefrom once a predetermined pressure has been 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 walls intersect as a point and the respective slit on each respective wall distal end extends from the point at which the walls intersect towards a lateral end of each respective wall such that the slits are co-joined at a respective proximal end thereof; and, at least one resilient support post located in the lateral end of, and covered by, each respective wall; wherein the second elastomeric part comprises at least one 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, wherein the support posts are formed with the first resilient part and the second elastomeric part is molded onto the first resilient part, and wherein at least one support region comprises a bellows.
