Abstract:
1. A dispenser for dispensing a fluid from a container, the dispenser comprising: an inlet for mounting to the container so as to receive therethrough the fluid; and an outlet which is configured to open to release fluid therefrom when a predetermined pressure is applied to the fluid in the dispenser at the outlet, and biased closed to retain fluid in the dispenser at a pressure less than the predetermined pressure; wherein a wall of a stiff resilient first material is provided at the outlet with one or more deformable elastomeric panels within the first material wall, adjacent to and contiguous with the first material, wherein the one or more panels are of a deformable elastomeric second material that is a different material-type from the stiff resilient first material, wherein the one or more deformable elastomeric panels being formed contiguously with the adjacent stiff resilient material defines a unitary wall surface construction comprising both the stiff resilient first material and the one or more deformable elastomeric panels second material at an outer surface of the outlet when biased closed, such that, when the predetermined pressure is applied to the fluid in the dispenser, the one or more panels deform to enable the adjacent stiff resilient material to flex and thus enable the outlet to open.
