Abstract
A fluid dispensing closure is provided for use on a squeeze-type container. The closure includes a resilient dome member projecting convexly outwardly over the opening. The dome member defines at least one slit extending through the dome member. The dome member is sufficiently resilient to have a normally closed configuration in which the slit is sealed closed when the pressure inside the dome member equals the pressure outside the dome member. The dome member is sufficiently flexible to be deformed further outwardly from and relative to the normally closed configuration for opening the slit when the container is squeezed to exert a predetermined fluid pressure against the inside of the dome member whereby the fluid product can discharge from the container through the open slit.
