Case 62-11003/GC 810 Canada SQUEEZE BOTTLE - TYPE DISPENSER Abstract of the Disclosure A squeeze bottle type dispenser is described which comprises a resiliently squeezable container for the liquid to be dispensed, a cover on the container which cover has a resilient central portion flexible outwardly of the cover away from the container, and, when flexed away therefrom, having a dispensing orifice therein and having an interior surface about the orifice facing toward the container, a dispensing valve body fixed in position in the container adjacent and underneath the cover and having at its outer end an exterior surface about the orifice of the outwardly flexible cover portion and with which the interior sur- face of the latter portion engages with gas tight seal when the parts of the dispenser are in the non-dispensing position, the interior of the valve body being hollow and the valve body having product-dispensing apertures opening from the hollow interior through the exterior surface thereof and being normally covered by the said inner surface of the flexible cover portion when the parts of the dispenser are in the non-dispensing position. The dispenser further comprises air return valve means therein opening an air return flow path into the container when the pressure outside the container is greater than the pressure inside the container, and liquid delivery means within the container connected to the valve body and adapted for delivering liquid to the hollow interior of the valve body when the container is squeezed. The dispenser has a space around the outside of the valve body which space is in communication with the upper portion of the interior of the container and opens into the gap between the exterior surface of the valve body and the interior surface of the resilient central portion of the cover, when the latter portion is moved away from the valve body for permitting compressed gas from within the container to flow through the gap when the container is squeezed.
